E CRSCTL Utility Reference

CRSCTL Overview

CRSCTL is an interface between you and Oracle Clusterware, parsing and calling Oracle Clusterware APIs for Oracle Clusterware objects.

Oracle Clusterware 11g release 2 (11.2) introduces cluster-aware commands with which you can perform check, start, and stop operations on the cluster. You can run these commands from any node in the cluster on another node in the cluster, or on all nodes in the cluster, depending on the operation.

You can use CRSCTL commands to perform several operations on Oracle Clusterware, such as:

• Starting and stopping Oracle Clusterware resources

• Enabling and disabling Oracle Clusterware daemons

• Checking the health of the cluster

• Managing resources that represent third-party applications

• Integrating Intelligent Platform Management Interface (IPMI) with Oracle Clusterware to provide failure isolation support and to ensure cluster integrity

• Debugging Oracle Clusterware components

Clusterized (Cluster Aware) Commands

You can run clusterized commands on one node to perform operations on another node in the cluster. These are referred to as remote operations. This simplifies administration because, for example, you no longer have to log in to each node to check the status of the Oracle Clusterware on all of your nodes.

Clusterized commands are completely operating system independent; they rely on the OHASD (Oracle High Availability Services daemon). If this daemon is running, then you can perform remote operations, such as the starting, stopping, and checking the status of remote nodes.

Clusterized commands include the following:

• crsctl check cluster

• crsctl start cluster

• crsctl stop cluster

Operational Notes

Usage Information

• The CRSCTL utility is located in the Grid_home/bin directory. To run CRSCTL commands, type in crsctl at the operating system prompt followed by the command and arguments, as shown in the following example:

  crsctl stop crs
  

• There are three categories of CRSCTL commands:

  • Those that you use in either the Oracle Real Application Clusters (Oracle RAC) environment or in the Oracle Restart environment

  • Those that you use in the Oracle RAC environment, only

  • Those that you use in the Oracle Restart environment, only

• Many CRSCTL commands use the -f option to force the command to run and ignore any checks.

  For example, if you specify the force option for the crsctl stop resource command on a resource that is running and has dependent resources that are also running, then the force option omits the error message and instead stops or relocates all the dependent resources before stopping the resource you reference in the command.

• Do not use versions of CRSCTL earlier than 11g release 2 (11.2) to manage Oracle Clusterware 11g release 2 (11.2).

Using CRSCTL Help

To print the help information for CRSCTL, use the following command:

crsctl -help

If you want help for a specific command, such as start, then enter the command and append -help to the end, as shown in the following example:

crsctl start -help

You can also use the abbreviations -h or -? (this option functions in Linux, UNIX, and Windows environments) instead of -help.

Deprecated Subprograms or Commands

The following commands are deprecated in Oracle Clusterware 11g release 2 (11.2) and are not supported in an Oracle Restart environment:

• crs_stat

• crs_register

• crs_unregister

• crs_start

• crs_stop

• crs_getperm

• crs_profile

• crs_relocate

• crs_setperm

• crsctl check crsd

• crsctl check cssd

• crsctl check evmd

• crsctl debug log

• crsctl set css votedisk

• crsctl start resources

• crsctl stop resources

CRSCTL Command Reference

This section is separated into three categories of CRSCTL commands:

• Dual Environment CRSCTL Commands

• Oracle RAC Environment CRSCTL Commands

• Oracle Restart Environment CRSCTL Commands

Dual Environment CRSCTL Commands

You can use the following commands in either the Oracle RAC or the Oracle Restart environments:

• crsctl add resource

• crsctl add type

• crsctl check css

• crsctl delete resource

• crsctl delete type

• crsctl get hostname

• crsctl getperm resource

• crsctl getperm type

• crsctl modify resource

• crsctl modify type

• crsctl setperm resource

• crsctl setperm type

• crsctl start resource

• crsctl status resource

• crsctl status type

• crsctl stop resource

crsctl add resource

Use the crsctl add resource command to register a resource to be managed by Oracle Clusterware. A resource could be an application process, a database, a service, a listener, and so on.

Syntax

crsctl add resource resource_name -type resource_type [-file file_path |
-attr "attribute_name=attribute_value,attribute_name=attribute_value,..."]
[-i] [-f]

Parameters

resource_name

-type resource_type

-file file_path

-attr "attribute_name=
attribute_value

-i

-f

Usage Notes

• Both the resource_name and -type resource_type parameters are required. You can create an associated resource type using the crsctl add type command.

• Any user can create a resource but only clusterware administrators can create resources of type local_resource or resources of type cluster_resource that have SERVER_POOLS=*.

  Once a resource is defined, its ACL controls who can perform particular operations with it. The Oracle Clusterware administrator list is no longer relevant.

  On Windows, a member of the Administrators group has full control over everything.

  See Also:

  "crsctl setperm resource" for more information about setting ACLs

• If an attribute value for an attribute name-value pair contains commas, then the value must be enclosed in single quotation marks ('').

• Following is an example of an attribute file:

  PLACEMENT=favored
  HOSTING_MEMBERS=node1 node2 node3
  RESTART_ATTEMPTS@CARDINALITYID(1)=0
  RESTART_ATTEMPTS@CARDINALITYID(2)=0
  FAILURE_THRESHOLD@CARDINALITYID(1)=2
  FAILURE_THRESHOLD@CARDINALITYID(2)=4
  FAILURE_INTERVAL@CARDINALITYID(1)=300
  FAILURE_INTERVAL@CARDINALITYID(2)=500
  CHECK_INTERVAL=2
  CARDINALITY=2
  

• Do not use this command for any resources with names that begin with ora because these resources are Oracle resources.

Example

Example 1

To register a VIP as a resource with Oracle Clusterware:

$ crsctl add resource app.appvip -type app.appvip.type -attr "RESTART_ATTEMPTS=2,
START_TIMEOUT=100,STOP_TIMEOUT=100,CHECK_INTERVAL=10,
USR_ORA_VIP=172.16.0.0,
START_DEPENDENCIES=hard(ora.net1.network)pullup(ora.net1.network),
STOP_DEPENDENCIES=hard(ora.net1.network)"

Example 2

To register a resources based on the test_type1 resource type:

$ crsctl add resource r1 -type test_type1 -attr "PATH_NAME=/tmp/r1.txt"
$ crsctl add resource r1 -type test_type1 -attr "PATH_NAME=/tmp/r2.txt"

crsctl add type

Use the crsctl add type command to create a resource type in Oracle Clusterware.

Syntax

Syntax

crsctl add crs administrator -u user_name [-f]

Parameters

-u user_name

-f

Usage Notes

• You must run this command as root or a cluster administrator, or an administrator on Windows systems

• By default, root, the user that installed Oracle Clusterware, and the * wildcard are members of the list of users who have Oracle Clusterware administrative privileges. Run the crsctl delete crs administrator command to remove the wildcard and enable role-separated management of Oracle Clusterware.

  See Also:

  "Role-Separated Management" for more information

Example

To add a user to the list of Oracle Clusterware administrators:

# crsctl add crs administrator -u scott

crsctl add css votedisk

Use the crsctl add css votedisk command to add one or more voting disks to the cluster on storage devices other than an Oracle ASM diskgroup.

Syntax

crsctl add css votedisk path_to_voting_disk [path_to_voting_disk ...] [-purge]

Parameters

path_to_voting_disk

-purge

Usage Notes

• You should have at least three voting disks, unless you have a storage device, such as a disk array, that provides external redundancy. Oracle recommends that you do not use more than 5 voting disks. The maximum number of voting disks that is supported is 15.

Example

To add a voting disk to the cluster:

$ crsctl add css votedisk /stor/grid/ -purge

crsctl add serverpool

Use the crsctl add serverpool command to add a server pool that is for hosting non-database resources (such as application servers) to Oracle Clusterware.

Syntax

crsctl add serverpool server_pool_name {-file file_path | 
                  -attr "attr_name=attr_value[,attr_name=attr_value[,...]]"}
                  [-i] [-f]

Parameters

server_pool_name

-file file_path

attribute_name

attribute_value

-attr "MAX_SIZE=30, IMPORTANCE=3"

-i

-f

Usage Notes

• The server_pool_name parameter is required.

• If an attribute value for an attribute name-value pair contains commas, then the value must be enclosed in single quotation marks ('').

• Do not use this command for any server pools with names that begin with ora because these server pools are Oracle server pools.

• Running this command may result in Oracle Clusterware relocating other servers between server pools to comply with the new configuration.

• You must run this command as root or a cluster administrator.

• Use the crsctl add serverpool command to create server pools that host non-database resources. To create server pools that host Oracle databases, use the SRVCTL command utility.

  See Also:

  Oracle Real Application Clusters Administration and Deployment Guide for information about using the SRVCTL command utility to create server pools

Example

Example 1

To add a server pool named testsp with a maximum size of 5 servers, run the following command as root or the Oracle Clusterware installation owner:

# crsctl add serverpool testsp -attr "MAX_SIZE=5"

Example 2

Create the sp1_attr file with the attribute values for the sp1 serverpool, each on its own line, as shown in the following example:

IMPORTANCE=1
MIN_SIZE=1
MAX_SIZE=2
SERVER_NAMES=node3 node4 node5
PARENT_POOLS=Generic
EXCLUSIVE_POOLS=testsp
ACL=owner:oracle:rwx,pgrp:oinstall:rwx,other::r--

Use the following command to create the sp1 server pool using the sp1_attr file as input:

$ crsctl add serverpool sp1 -file /tmp/sp1_attr

crsctl check cluster

Use the crsctl check cluster command on any node in the cluster to check the status of the Oracle Clusterware stack.

Syntax

crsctl check cluster [-all | [-n server_name [...]]

Usage Notes

• You can check the status of the Oracle Clusterware stack on all nodes in the cluster with the -all option or you can specify one or more space-delimited nodes. If you do not specify either option, Oracle Clusterware checks the status of the Oracle Clusterware stack on the local server.

• You can use this cluster-aware command on any node in the cluster.

Example

The crsctl check cluster command returns output similar to the following:

$ crsctl check cluster -all
*****************************************************************
node1:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
*****************************************************************
node2:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
*****************************************************************

crsctl check crs

CRS-4638: Oracle High Availablity Services is online
CRS-4537: Cluster Ready Services is onlin
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online

crsctl check resource

Use the crsctl check resource command to initiate the check action inside the application-specific agent of a particular resource. Oracle Clusterware only provides output if something prevents the system from issuing the check request, such as a bad resource name.

Syntax

crsctl check resource {resource_name [...] | -w "filter" }
      [-n node_name] [-k cardinality_id] [-d degree_id] }

Parameters

resource_name

-w "filter"

-n node_name

-k cardinality_id

-d degree_id

Usage Notes

• You must have read and execute permissions on the specified resources to check them

• Do not use this command for any resources with names that begin with ora because these resources are Oracle resources

• If this command is successful, it only means that a check was issued; it does not mean the CHECK action has been completed

Example

To initiate the check action inside the application-specific agent of a particular resource:

$ crsctl check resource appsvip

crsctl check ctss

Use the crsctl check ctss command to check the status of the Cluster Time Synchronization services.

Syntax

crsctl check ctss

Example

The crsctl check ctss command returns output similar to the following:

CRS-4700: The Cluster Time Synchronization Service is in Observer mode.

or

CRS-4701: The Cluster Time Synchronization Service is in Active mode.
CRS-4702: Offset from the reference node (in msec): 100

crsctl config crs

Use the crsctl config crs command to display Oracle High Availability Services automatic startup configuration.

Syntax

crsctl config crs

Example

The crsctl config crs command returns output similar to the following:

CRS-4622: Oracle High Availability Services autostart is enabled.

Parameters

-u user_name

-f

Usage Notes

• The user_name parameter is required

• You must run this command as root or a cluster administrator, or an administrator on Windows systems

• To enable role-separated management, you must remove the * value enclosed in double quotation marks ("")

Example

To remove a user from the list of cluster administrators:

# crsctl delete crs administrator -u scott

crsctl delete css votedisk

Use the crsctl delete css votedisk to remove a voting disk from the Oracle Clusterware configuration.

Syntax

crsctl delete css votedisk voting_disk_GUID [voting_disk_GUID [...]]

Parameters

voting_disk_GUID

Usage Notes

• You can use this command only to remove voting disks from non-Oracle ASM storage devices

• You can obtain the file universal identifiers of each current voting disk by running the crsctl query css votedisk command

Example

To remove a voting disk:

$ crsctl delete css votedisk 26f7271ca8b34fd0bfcdc2031805581e

crsctl delete node

Use the crsctl delete node to remove a node from the cluster.

Syntax

crsctl delete node -n node_name

crsctl delete serverpool

Use the crsctl delete serverpool command to remove a server pool from the Oracle Clusterware configuration.

Syntax

crsctl delete serverpool server_pool_name [server_pool_name [...]] [-i]

Usage Notes

• The server_pool_name parameter is required

• If you specify -i, then the command fails if Oracle Clusterware cannot process the request immediately

• Do not use this command for any server pools with names that begin with ora because these server pools are Oracle server pools

• While you can use this command in either environment, it is only useful in the Oracle RAC environment

Example

To delete a server pool, run the following command as root or the Oracle Clusterware installation owner:

# crsctl delete serverpool sp1

crsctl disable crs

Use the crsctl disable crs command to prevent the automatic startup of Oracle High Availability Services when the server boots.

Syntax

crsctl disable crs

Usage Notes

• This command only affects the local server

• If you disable Oracle High Availability Services automatic startup, you must use the crsctl start crs command to start Oracle High Availability Services

Example

The crsctl disable crs command returns output similar to the following:

crsctl stop cluster

Use the crsctl stop cluster command on any node in the cluster to stop the Oracle Clusterware stack on all servers in the cluster or specific servers.

Syntax

crsctl stop cluster [-all | -n server_name [...]] [-f]

Usage Notes

• If you do not specify -all or one or more space-delimited server names, then Oracle Clusterware stops the Oracle Clusterware stack on the local server.

• You can use this cluster-aware command on any node in the cluster.

• This command attempts to gracefully stop resources managed by Oracle Clusterware while attempting to stop the Oracle Clusterware stack.

  If any resources that Oracle Clusterware manages are still running after you run the crsctl stop cluster command, then the command fails. Use the -f option to unconditionally stop all resources and stop the Oracle Clusterware stack.

• If you intend to stop Oracle Clusterware on all or a list of nodes, then use the crsctl stop cluster command, because it prevents certain resources from being relocated to other servers in the cluster before the Oracle Clusterware stack is stopped on a particular server. If you must stop the Oracle High Availability Services on one or more nodes, then wait until the crsctl stop cluster command completes and then run the crsctl stop crs command on any particular nodes, as necessary.

Example

To stop the Oracle Clusterware stack on a particular server:

# crsctl stop cluster -n node1

crsctl stop crs

Use the crsctl stop crs command to stop Oracle High Availability Services on the local server.

Syntax

crsctl stop crs [-f]

Usage Notes

• This command attempts to gracefully stop resources managed by Oracle Clusterware while attempting to stop Oracle High Availability Services on the local server.

  If any resources that Oracle Clusterware manages are still running after you run the crsctl stop crs command, then the command fails. Use the -f option to unconditionally stop all resources and stop Oracle High Availability Services on the local server.

• If you intend to stop Oracle Clusterware on all or a list of nodes, then use the crsctl stop cluster command, because it prevents certain resources from being relocated to other servers in the cluster before the Oracle Clusterware stack is stopped on a particular server. If you must stop the Oracle High Availability Services on one or more nodes, then wait until the crsctl stop cluster command completes and then run the crsctl stop crs command on any particular nodes, as necessary.

Example

To stop Oracle High Availability Services on the local server:

# crsctl stop crs

crsctl stop ip

Use the crsctl stop ip command to stop a given IP name or IP address on a specified interface with a specified subnet mask. Run this command on the server on which you want to stop the IP.

Syntax

crsctl stop ip -A {IP_name | IP_address}/interface_name

Parameters

{IP_name | IP_address}

interface_name

crsctl unpin css

Use the crsctl unpin css command to unpin many servers. If a node is not pinned, its node number may change if the lease expires while it is down.

Syntax

crsctl unpin css -n node_name [node_name [...exit]]

Usage Notes

• You can specify a space-delimited list of nodes.

• Unpinned servers that stop for longer than a week are no longer reported by olsnodes. These servers are dynamic when they leave the cluster, so you do not need to explicitly remove them from the cluster.

• Deleting a node with the crsctl delete node command implicitly unpins the node.

• During upgrade of Oracle Clusterware, all servers are pinned, whereas after a fresh installation of Oracle Clusterware 11g release 2 (11.2), all servers you add to the cluster are unpinned.

• You cannot unpin a server that has an instance of Oracle RAC that is older than 11g release 2 (11.2) if you installed Oracle Clusterware 11g release 2 (11.2) on that server.

Example

To unpin two nodes:

$ crsctl unpin css -n node1 node4

crsctl unset css

Use the crsctl unset css command to restore the value of a Cluster Synchronization Services parameter to its default value.

Syntax

crsctl unset css parameter

Usage Notes

• There are four Cluster Synchronization Services parameters you can specify:

  • diagwait:

  • disktimeout:

  • misscount:

  • reboottime:

Example

To restore the reboottime Cluster Synchronization Services parameter to its default value:

$ crsctl unset css reboottime

crsctl unset css ipmiconfig

Use the crsctl unset css ipmiconfig command to clear all previously stored IPMI configuration (login credentials and IP address) from the Oracle Local Registry. This is appropriate when deconfiguring IPMI in your cluster or if IPMI configuration was previously stored by the wrong user.

Syntax

crsctl unset css ipmiconfig

Usage Notes

• This command must be run under the user account originally used to configure IPMI or by a privileged user.

• This command only clears the IPMI configuration on the server on which you run it.

• If Oracle Clusterware was able to access and use the deleted configuration, then it will continue to do so until you restart Oracle Clusterware.

Example

To clear the IPMI configuration data from the Oracle Local Registry and restart Oracle Clusterware to prevent further use of IPMI, log in as root or a member of the Administrator's group on Windows and run the following commands:

crsctl unset css ipmiconfig
crsctl stop crs
crsctl start crs

Oracle Restart Environment CRSCTL Commands

The commands listed in this section control Oracle High Availability Services. These commands manage the Oracle High Availability Services stack in the Oracle Restart environment, which consists of the Oracle High Availability Services daemon (ohasd), Oracle ASM (if installed), and Cluster Synchronization Services (if Oracle ASM is installed). These commands only affect the local server on which you run them.

Each server in the cluster is in one of two possible states:

• The whole stack is up, which means that Oracle High Availability Services is active

• The whole stack is down, which means that Oracle High Availability Services is inactive

You can use the following commands in the Oracle Restart environment, only:

• crsctl check has

• crsctl config has

• crsctl disable has

• crsctl enable has

• crsctl query has releaseversion

• crsctl query has softwareversion

• crsctl start has

• crsctl stop has

crsctl check has

Use the crsctl check has command to check the status of ohasd.

Syntax

crsctl check has

Usage Notes

Example

The crsctl check has command returns output similar to the following:

CRS-4638: Oracle High Availability Services is online

crsctl config has

Use the crsctl check has command to display the automatic startup configuration of the Oracle High Availability Services stack on the server.

Syntax

crsctl config has

Usage Notes

Example

The crsctl config has command returns output similar to the following:

CRS-4622 Oracle High Availability Services autostart is enabled.

crsctl disable has

Use the crsctl disable has command to disable automatic startup of the Oracle High Availability Services stack when the server boots up.

Syntax

crsctl disable has

Usage Notes

Example

The crsctl disable has command returns output similar to the following:

CRS-4621 Oracle High Availability Services autostart is disabled.

crsctl enable has

Use the crsctl enable has command to enable automatic startup of the Oracle High Availability Services stack when the server boots up.

Syntax

crsctl enable has

Usage Notes

Example

The crsctl enable has command returns output similar to the following:

CRS-4622 Oracle High Availability Services autostart is enabled.

crsctl query has releaseversion

Use the crsctl query crs releaseversion command to display the release version of the Oracle Clusterware software on the local node.

Syntax

crsctl query has releaseversion

Usage Notes

Example

The crsctl query has releaseversion command returns output similar to the following:

Oracle High Availability Services release version on the local node is [11.2.0.0.2]

crsctl query has softwareversion

Use the crsctl query has softwareversion command to display the software version on the local node.

Syntax

crsctl query has softwareversion

Usage Notes

• If you do not provide a server name, then Oracle Clusterware displays the version of Oracle Clusterware running on the local server.

Example

The crsctl query has softwareversion command returns output similar to the following:

Oracle High Availability Services version on the local node is [11.2.0.2.0]

crsctl start has

Use the crsctl start has command to start Oracle High Availability Services on the local server.

Syntax

crsctl start has

Usage Notes

Example

To start Oracle High Availability Services on the local server:

# crsctl start has

crsctl stop has

Use the crsctl stop has command to stop Oracle High Availability Services on the local server.

Syntax

crsctl stop has [-f]

Usage Notes

• This command attempts to gracefully stop resources managed by Oracle Clusterware while attempting to stop Oracle High Availability Services.

  If any resources that Oracle Clusterware manages are still running after you run the crsctl stop has command, then the command fails. Use the -f option to unconditionally stop all resources and stop Oracle High Availability Services.

Example

To stop Oracle High Availability Services on the local server:

# crsctl stop has

Troubleshooting and Diagnostic Output

You can use crsctl set log commands as the root user to enable dynamic debugging for Cluster Ready Services (CRS), Cluster Synchronization Services (CSS), and the Event Manager (EVM), and the clusterware subcomponents. You can dynamically change debugging levels using crsctl debug commands. Debugging information remains in the Oracle Cluster Registry (OCR) for use during the next startup. You can also enable debugging for resources.

This section covers the following topics:

• Dynamic Debugging

• Component Level Debugging

• Enabling Debugging for Oracle Clusterware Resources

• Enabling Additional Tracing for Oracle Clusterware Components

Dynamic Debugging

This section includes the following CRSCTL commands that aid in debugging:

• crsctl set log

crsctl set log

Use the crsctl set log command to set log levels for Oracle Clusterware.

Syntax

crsctl set log {[crs | css | evm "component_name=log_level, [...]"] | 
[all=log_level]}

You can also set log levels for the agents of specific resources, as follows:

crsctl set log res "resource_name=log_level, [...]"

Usage Notes

• You can set log levels for various components of the three modules, CRS, CSS, and EVM. If you choose the all option, then you can set log levels for all components of one module with one command. Use the crsctl lsmodules command to obtain a list of components for each module.

• Enter a comma-delimited list of component name-log level pairs enclosed in double quotation marks ("").

  Note:

  Separate component name-log level pairs with an equals sign (=) in Oracle Clusterware 11g release 2 (11.2). Previous Oracle Clusterware versions used a colon (:).

• The log_level is a number from 1 to 5 that sets the log level for the component or resource, where 1 is the least amount of log output and 5 provides the most detailed log output. The default log level is 2.

• To set log levels for resources, specify the name of a particular resource, or a comma-delimited list of resource name-log level pairs enclosed in double quotation marks ("").

Examples

To set log levels for the CRSRTI and CRSCOMM components of the CRS module:

$ crsctl set log crs "CRSRTI=1,CRSCOMM=2"

To set log levels for all components of the EVM module:

$ crsctl set log evm all=2

To set a log level for a resource:

$ crsctl set log res "myResource1=3"

Component Level Debugging

You can use crsctl set log and crsctl set trace commands as the root user to enable dynamic debugging for the various Oracle Clusterware modules.

This section includes the following topics:

• Enabling Debugging for Oracle Clusterware Modules

• Creating an Initialization File to Contain the Debugging Level

Enabling Debugging for Oracle Clusterware Modules

You can enable debugging for Oracle Clusterware modules and their components, and for resources, by setting environment variables or by running crsctl set log commands, using the following syntax:

crsctl set {log | trace} module_name "component:debugging_level
[,component:debugging_level][,...]"

Run the crsctl set command as the root user, and supply the following information:

• module_name: The name of one of the following modules:

  
  mdns: Multicast domain name server
  gpnp: Grid Plug and Play service
  css: Cluster Synchronization Services
  crf: Cluster Health Monitor
  crs: Cluster Ready Services
  ctss: Cluster Time Synchronization Service
  evm: Event Manager
  gipc: Grid Interprocess Communication
  

• component: The name of a component for one of the modules. See Table E-40 for a list of all of the components.

• debugging_level: A number from 1 to 5 to indicate the level of detail you want the debug command to return, where 1 is the least amount of debugging output and 5 provides the most detailed debugging output. The default debugging level is 2.

  You can dynamically change the debugging level in the crsctl command or you can configure an initialization file for changing the debugging level, as described in "Creating an Initialization File to Contain the Debugging Level".

The following commands show examples of how to enable debugging for the various modules:

• To enable debugging for Oracle Clusterware:

  crsctl set log crs "CRSRTI:1,CRSCOMM:2"
  

• To enable debugging for OCR:

  crsctl set log crs "CRSRTI:1,CRSCOMM:2,OCRSRV:4"
  

• To enable debugging for EVM:

  crsctl set log evm "EVMCOMM:1"
  

• To enable debugging for resources

  crsctl set log res "resname:1"
  

To obtain a list of components that can be used for debugging, run the crsctl lsmodules command, as follows:

crsctl lsmodules {mdns | gpnp | css | crf | crs | ctss | evm | gipc}

Table E-40 shows the components for the CRS, CSS, and EVM modules, respectively. Note that some component names are common between the CRS, EVM, and CSS daemons and may be enabled on that specific daemon. For example, COMMNS is the NS layer and because each daemon uses the NS layer, you can enable this specific module component on any of the daemons to get specific debugging information.

CRSCOMM
CRSRTI
CRSMAIN
CRSPLACE
CRSAPP
CRSRES
CRSCOMM
CRSOCR

^Footnote 1 Obtain the list of CRS components using the crsctl lsmodules crs command.

^Footnote 2 Obtain the list of CSS components using the crsctl lsmodules css command.

^Footnote 3 Obtain the list of EVM components using the crsctl lsmodules evm command.

Example 1    

To set debugging levels on specific cluster nodes, include the -nodelist keyword and the names of the nodes, as follows:

crsctl set log crs "CRSRTI:1,CRSCOMM:2" -nodelist node1,node2

Table E-41 describes the Cluster Synchronization Services modules.

Table E-42 describes the function of each communication (COMM) module.

Table E-43 describes the functions performed by each CRS module.

Using the crsctl set log crs command, you can debug the OCR components listed in Table E-44. The components listed in Table E-44 can also be used for the Oracle Local Registry (OLR) except for OCRMAS and OCRASM. You can also use them for OCR and OLR clients, except for OCRMAS and OCRSRV. Some OCR and OLR clients are OCRCONFIG, OCRDUMP, and so on.

Table E-45 describes the OCR tool modules.

Creating an Initialization File to Contain the Debugging Level

This section describes how to specify the debugging level in an initialization file. This debugging information is stored for use during the next startup.

For each process to debug, you can create an initialization file that contains the debugging level.

The initialization file name includes the name of the process that you are debugging (process_name.ini). The file is located in the Grid_home/log/host_name/admin/ directory. For example, the name for the CLSCFG debugging initialization file on node1 would be:

Grid_home/log/node1/admin/clscfg.ini

You can also use an initialization file when using OCR utilities. The initialization file for ocrconfig, ocrdump, and ocrcheck is:

Grid_home/srvm/admin/ocrlog.ini

The format of the initialization file is as follows:

mesg_logging_level=2
comploglvl=”OCRAPI:0;OCRSRV:0”
comptrclvl=”OCRAPI:0;OCRSRV:0”

You can specify component names, logging, and tracing levels.

Enabling Debugging for Oracle Clusterware Resources

You can enable debugging for Oracle Clusterware resources by running the crsctl set log command, using the following syntax:

crsctl set log res "resource_name=debugging_level"

Run the crsctl set log command as the root user, and supply the following information:

• resource_name: The name of the resource to debug.

• debugging_level: A number from 1 to 5 to indicate the level of detail you want the debug command to return, where 1 is the least amount of debugging output and 5 provides the most detailed debugging output. The default debugging level is 2.

  You can dynamically change the debugging level in the crsctl command or you can configure an initialization file for changing the debugging level, as described in "Creating an Initialization File to Contain the Debugging Level".

To obtain a list of resources that can be used for debugging, run the crsctl status resource command.

Example 1    

To generate a debugging log for the VIP resource on node1, issue the following command:

crsctl set log res "ora.node1.vip:1"

Enabling Additional Tracing for Oracle Clusterware Components

My Oracle Support may ask you to enable tracing to capture additional information. Because the procedures described in this section may affect performance, only perform these activities with the assistance of My Oracle Support.

You can enable tracing for Oracle Clusterware resources by running the crsctl set trace command, using the following syntax:

crsctl set trace "component_name=tracing_level,..."

Run the crsctl set trace command as the root user, and supply the following information:

• component_name: The name of the component you want to trace. The command accepts the following:

  {mdns | gpnp | css | crf | crs | ctss | evm | gipc}
  

  The components are, as follows:

  
  mdns: Multicast domain name server
  gpnp: Grid Plug and Play service
  css: Cluster Synchronization Services
  crf: Cluster Health Monitor
  crs: Cluster Ready Services
  ctss: Cluster Time Synchronization Service
  evm: Event Manager
  gipc: Grid Interprocess Communication
  

• tracing_level: A number from 1 to 5 to indicate the level of detail you want the trace command to return, where 1 is the least amount of tracing output and 5 provides the most detailed tracing output.

Example 1    

To generate a trace file for Cluster Synchronization Services, use the following command:

crsctl set trace "css=3"
