This chapter explains how to use the Enterprise Manager command line utility (emctl) to start and stop the Management Service, the Management Agent, the Grid Control Console, the Fusion Middleware Control Console, and Database Control.
This chapter also explains the various emctl commands, exit codes, and how to use log information to troubleshoot emctl.
Following are the sections in this chapter:
Guidelines for Starting Multiple Enterprise Manager Components on a Single Host
Starting and Stopping Oracle Enterprise Manager 11g Grid Control
The following sections describe how to use the Enterprise Manager command line utility (emctl) to control the Oracle Management Agent:
To start, stop, or check the status of the Management Agent on UNIX systems:
Change directory to the AGENT_HOME/bin directory.
Use the appropriate command described in Table 7-1.
For example, to stop the Management Agent, enter the following commands:
$PROMPT> cd AGENT_HOME/bin
$PROMPT> ./emctl stop agent
Table 7-1 Starting, Stopping, and Checking the Status of the Management Agent
| Command | Purpose |
|---|---|
|

|
|
Stops the Management Agent |
|
|
If the Management Agent is running, this command displays status information about the Management Agent, including the Agent Home, the process ID, and the time and date of the last successful upload to the Management Repository (). |

On IBM AIX environment with a large memory configuration where the Management Agent is monitoring a large number of targets, the Agent may not start. To prevent this issue, prior to starting the Management Agent, set the following variables in the shell:
LDR_CNTRL="MAXDATA=0x80000000"@NOKRTL AIX_THREADSCOPE=S
The LDR_CNTRL variable sets the data segment size and disables loading of run time libraries in kernel space. The AIX_THREADSCOPE parameter changes AIX Threadscope context from the default Processwide 'P' to Systemwide 'S'. This causes less mutex contention.
When you install the Oracle Management Agent on a Windows system, the installation procedure creates three new services in the Services control panel.
The procedure for accessing the Services control panel varies, depending upon the version of Microsoft Windows you are using. For example, on Windows 2000, locate the Services Control panel by selecting Settings and then Administrative Tools from the Start menu.
Note:
Theemctl utility described in Controlling the Management Service on UNIX is available in the bin subdirectory of the Oracle home where you installed the Management Agent; however, Oracle recommends that you use the Services control panel to start and stop the Management Agent on Windows systems.Table 7-2 describes the Windows services that you use to control the Management Agent.

Use this service only if you are using the advanced features of the Simple Network Management Protocol (SNMP). For more information, see the Oracle SNMP Support Reference Guide. |
|
Oracle<oracle_home>SNMPPeerMasterAgent For example: OracleOraHome1PeerMasterAgent |
Use this service only if you are using the advanced features of the Simple Network Management Protocol (SNMP). For more information, see the Oracle SNMP Support Reference Guide. |
Note:
If you are having trouble starting or stopping the Management Agent on a Windows NT system, try stopping the Management Agent using the following emctl command:$PROMPT> <AGENT_HOME>\bin\emctl istop agent
After stopping the Management Agent using the emctl istop agent command, start the Management Agent using the Services control panel.
This problem and solution applies only to the Windows NT platform, not to other Windows platforms, such as Windows 2000 or Windows XP systems.
To check the status of the Management Agent on Windows systems:
Change directory to the following location in the AGENT_HOME directory:
AGENT_HOME\bin
Enter the following emctl command to check status of the Management Agent:
$PROMPT> .\emctl status agent
If the Management Agent is running, this command displays status information about the Management Agent, including the Agent Home, the process ID, and the time and date of the last successful upload to the Management Repository ().
The following sections describe how to control the Oracle Management Service:
To start and stop the Oracle Management Service on UNIX systems, use a set of emctl commands.
To start, stop, or check the status of the Management Service with the Enterprise Manager command-line utility:
Change directory to the ORACLE_HOME/bin directory in the Management Service home.
Use the appropriate command described in Table 7-3.
For example, to stop the Management Service, enter the following commands:
$PROMPT> cd bin $PROMPT> ./emctl stop oms

| Component | Service Name Format | Description |
|---|---|---|
OracleWeblogicNodeManager_EMGC_OMS1_1 |
Use this service to start and stop the node manager of the WebLogic Server that was installed and configured to deploy the Management Service J2EE application. |
|
OracleManagementServer_EMGC_OMS1_1 |
Use this service to start and stop all components that were installed and configured as part of the Management Service J2EE application. |
Fusion Middleware Control is a component of Oracle Fusion Middleware 11g that is installed as part of any WebLogic Server installation. For information about starting and stopping Fusion Middleware Control, see the chapter on Starting and Stopping Oracle Fusion Middleware in the Oracle® Fusion Middleware Administrator's Guide available on OTN.
To control the Database Control, you use the emctl command-line utility that is available in the ORACLE_HOME/bin directory after you install Oracle Database 11g.
To start the Database Control, as well the Management Agent and the Management Service associated with the Database Control:
To stop the Database Control, as well the Management Agent and the Management Service associated with the Database Control:
To start or stop the Database Control on Windows systems:
Open the Services control panel.
For example, on Windows NT, select Start, point to Settings, select Control Panel, and then double-click the Services icon.
On Windows 2000, select Start, point to Administrative Tools, and select Services.
Locate the Database Control in the list of services.
The name of the service is usually consists of "Oracle", followed by the name of the home directory you specified during the installation and the database system identifier (SID), followed by the word "DBControl." For example, if you specified DBd11g as the Oracle Home, the Service name would be:
OracleDB11gDBControl
After you locate the service, you can use the Services control panel to start or stop the Database Control service.
By default, the Database Control service is configured to start automatically when the system starts.
Oracle Enterprise Manager 11g components are used to manage a variety of Oracle software products. In most cases, in a production environment, you will want to distribute your database and WebLogic Server instances among multiple hosts to improve performance and availability of your software resources. However, in cases where you must install multiple WebLogic Servers or databases on the same host, consider the following guidelines.
When you start Fusion Middleware Control, the Management Agent, or the Database Control, Enterprise Manager immediately begins gathering important monitoring data about the host and its managed targets. Keep this in mind when you develop a process for starting the components on the host.
Specifically, consider staggering the startup process so that each Enterprise Manager process has a chance to start before the next process begins its startup procedure. When you start up all the components (for example, after a restart of the system), use a process such as the following:
Use the emctl start command to start all the OPMN-managed processes in the WebLogic Server home directory.
Wait 15 seconds.
Run the StartWebLogic.sh script to start HTTP services for WebLogic Server.
Wait 15 seconds.
Use the emctl start agent command to start the Management Agent for the host.
Using a staggered startup procedure such as the preceding example will ensure that the processes are not in contention for resources during the CPU-intensive startup phase for each component.
As described in the previous sections, you use separate commands to control the Oracle Management Service, Oracle Management Agent, and the Oracle Fusion Middleware components on which the Grid Control depends.
The following sections describe how to stop and start all the Grid Control components that are installed by the Oracle Enterprise Manager 11g Grid Control Console installation procedure.
You can use this procedure to start all the framework components after a system reboot or to shutdown all the components before bringing the system down for system maintenance.
The following procedure summarizes the steps required to start all the components of the Grid Control. For example, use this procedure if you have restarted the host computer and all the components of the Grid Control have been installed on that host.
To start all the Grid Control components on a host, use the following procedure:
If your Oracle Management Repository resides on the host, change directory to the Oracle Home for the database where you installed the Management Repository and start the database and the Net Listener for the database:
Set the ORACLE_HOME environment variable to the Management Repository database home directory.
Set the ORACLE_SID environment variable to the Management Repository database SID (default is asdb).
Start the Net Listener:
$PROMPT> $ORACLE_HOME/bin/lsnrctl start
Start the Management Repository database instance:
ORACLE_HOME/bin/sqlplus /nolog
SQL> connect SYS as SYSDBA
SQL> startup
SQL> quit
See Also:
Oracle Database Administrator's Guide for information about starting and stopping an Oracle DatabaseStart the Oracle Management Service:
$PROMPT> ORACLE_HOME/bin/emctl start oms
Run the StartWebLogic.sh script to start HTTP services for WebLogic Server:
Change directory to the home directory for the Oracle Management Agent and start the Management Agent:
$PROMPT> AGENT_HOME/bin/emctl start agent
Note:
Be sure to run theemctl start agent command in the Oracle Management Agent home directory and not in the Management Service home directory.The following procedure summarizes the steps required to stop all the components of the Grid Control. For example, use this procedure if you have installed all the components of the Grid Control on the same host you want to shut down or restart the host computer.
To stop all the Grid Control components on a host, use the following procedure:
Stop the Oracle Management Service:
$PROMPT> $ORACLE_HOME/bin/emctl stop oms
Run the StartWebLogic.sh script to start HTTP services for WebLogic Server.
Change directory to the home directory for the Oracle Management Agent and stop the Management Agent:
$PROMPT> AGENT_HOME/bin/emctl stop agent
Note:
Be sure to run theemctl stop agent command in the Oracle Management Agent home directory and not in the Oracle WebLogic Server home directory.If your Oracle Management Repository resides on the same host, change directory to the Oracle Home for the database where you installed the Management Repository and stop the database and the Net Listener for the database:
Set the ORACLE_HOME environment variable to the Management Repository database home directory.
Set the ORACLE_SID environment variable to the Management Repository database SID (default is asdb).
Stop the database instance:
$PROMPT> ORACLE_HOME/bin/sqlplus /nolog SQL> connect SYS as SYSDBA SQL> shutdown SQL> quit
See Also:
Oracle Database Administrator's Guide for information about starting and stopping an Oracle DatabaseStop the Net Listener:
$PROMPT> $ORACLE_HOME/bin/lsnrctl stop
The following sections describe additional emctl commands you can use to control the Management Agent:
Under normal circumstances, the Management Agent uploads information about your managed targets to the Management Service at regular intervals.
However, there are two Enterprise Manager commands that can help you force an immediate upload of data to the Management Service or a reload of the target definitions and attributes stored in the Management Agent home directory.
To use these commands, change directory to the AGENT_HOME/bin directory (UNIX) or the AGENT_HOME\bin directory (Windows) and enter the appropriate command as described in Table 7-5.
Table 7-5 Manually Reloading and Uploading Management Data
| Command | Description |
|---|---|
|
Use this command to force an immediate upload of the current management data from the managed host to the Management Service. Use this command instead of waiting until the next scheduled upload of the data. |
|
|
This command can be used to modify the Note: Oracle does not support manual editing of the |
To monitor the performance of your database targets, Enterprise Manager connects to your database using a database user name and password. This user name and password combination is referred to as the database monitoring credentials.
Note:
The instructions in this section are specific to the monitoring credentials for a database target, but you can use this procedure for any other target type that requires monitoring credentials. For example, you can use this procedure to specify new monitoring credentials for your Oracle Management Service and Management Repository.When you first add an Oracle9i Database target, or when it is added for you during the installation of the Management Agent, Enterprise Manager uses the DBSNMP database user account and the default password for the DBSNMP account as the monitoring credentials.
When you install Oracle Database 11g, you specify the DBSNMP monitoring password during the database installation procedure.
As a result, if the password for the DBSNMP database user account is changed, you must modify the properties of the database target so that Enterprise Manager can continue to connect to the database and gather configuration and performance data.
Similarly, immediately after you add a new Oracle Database 11g target to the Grid Control, you may need to configure the target so it recognizes the DBSNMP password that you defined during the database installation. Otherwise, the Database Home page may display no monitoring data and the status of the database may indicate that there is a metric collection error.
You can modify the Enterprise Manager monitoring credentials by using the Oracle Enterprise Manager 11g Grid Control Console or by using the Enterprise Manager command line utility (emctl).
To modify the password for the DBSNMP account in the Oracle Enterprise Manager 11g Grid Control Console:
Click the Targets tab in the Grid Control Console.
Click the Database subtab to list the database targets you are monitoring.
Select the database and click Configure.
Enterprise Manager displays the Configure Database: Properties page.
Enter the new password for the DBSNMP account in the Monitor Password field.
Click Test Connection to confirm that the monitoring credentials are correct.
If the connection is successful, continue to the end of the Database Configuration wizard and click Submit.
To enter new monitoring credentials with the Enterprise Manager command-line utility:
Change directory to the AGENT_HOME/bin directory (UNIX) or the AGENT_HOME\bin directory (Windows).
Enter the following command to specify new monitoring credentials:
$PROMPT>./emctl config agent credentials [Target_name[:Target_Type]]
To determine the correct target name and target type, see "Listing the Targets on a Managed Host".
shows an example of the prompts and the output you receive from the command.
Example 7-2 Modifying the Database Monitoring Credentials

There are times when you need to provide the name and type of a particular target you are managing. For example, you must know the target name and type when you are setting the monitoring credentials for a target.
To list the name and type of each target currently being monitored by a particular Management Agent:
Change directory to the AGENT_HOME/bin directory (UNIX) or the AGENT_HOME\bin directory (Windows).
Enter the following command to specify new monitoring credentials:
$PROMPT>./emctl config agent listtargets
To list targets fully, use the following command:
$PROMPT>./emctl config agent listtargetsfully

Blackouts allow Enterprise Manager users to suspend management data collection activity on one or more managed targets. For example, administrators use blackouts to prevent data collection during scheduled maintenance or emergency operations.
See Also:
The "Systems Monitoring" chapter in Oracle Enterprise Manager Concepts for more information about Enterprise Manager blackoutsYou can control blackouts from the Oracle Enterprise Manager 11g Grid Control Console or from the Enterprise Manager command line utility (emctl). However, if you are controlling target blackouts from the command line, you should not attempt to control the same blackouts from the Grid Control Console. Similarly, if you are controlling target blackouts from the Grid Control Console, do not attempt to control those blackouts from the command line.
See Also:
"Creating, Editing, and Viewing Blackouts" in the Enterprise Manager online help for information about controlling blackouts from the Grid Control ConsoleFrom the command line, you can perform the following blackout functions:
Starting Immediate Blackouts
Stopping Immediate Blackouts
Checking the Status of Immediate Blackouts
Note:
When you start a blackout from the command line, any Enterprise Manager jobs scheduled to run against the blacked out targets will still run. If you use the Grid Control Console to control blackouts, you can optionally prevent jobs from running against blacked out targets.To use the Enterprise Manager command-line utility to control blackouts:
Change directory to the AGENT_HOME/bin directory (UNIX) or the AGENT_HOME\bin directory (Windows).
Enter the appropriate command as described in Table 7-6.
Note:
When you start a blackout, you must identify the target or targets affected by the blackout. To obtain the correct target name and target type for a target, see "Listing the Targets on a Managed Host".Table 7-6 Summary of Blackout Commands
Use the following examples to learn more about controlling blackouts from the Enterprise Manager command line:
To start a blackout called "bk1" for databases "db1" and "db2," and for Oracle Listener "ldb2," enter the following command:
$PROMPT> emctl start blackout bk1 db1 db2 ldb2:oracle_listener -d 5 02:30
The blackout starts immediately and will last for 5 days 2 hours and 30 minutes.
To check the status of all the blackouts on a managed host:
$PROMPT> emctl status blackout
To stop blackout "bk2" immediately:
$PROMPT> emctl stop blackout bk2
To start an immediate blackout called "bk3" for all targets on the host:
$PROMPT> emctl start blackout bk3 -nodeLevel
To start an immediate blackout called "bk3" for database "db1" for 30 minutes:
$PROMPT> emctl start blackout bk3 db1 -d 30
To start an immediate blackout called "bk3" for database "db2" for five hours:
$PROMPT> emctl start blackout bk db2 -d 5:00
The Management Agent may fail to start after the upgrade if it realizes that it is no longer in the same time zone that it was originally configured with.
You can reset the time zone used by the Management Agent using the following command:
emctl resetTZ agent
This command will correct the Management Agent side time zone and specify an additional command to be run against the Management Repository to correct the value there.
IMPORTANT:
Before you change the Management Agent time zone, first check to see if there are any blackouts that are currently running or scheduled to run on any target managed by that Management Agent.
To check for blackouts:
In the Grid Control Console, go to the All Targets page under the Targets tab, and locate the Management Agent in the list of targets. Click on the Management Agent's name. This brings you to the Management Agent's home page.
The list of targets monitored by the Management Agent are listed in the "Monitored Targets" section.
For each of target in the list:
Click the target name. This brings you to the target's home page.
In the Related Links section of the home page, click the Blackouts link. This allows you to check any currently running blackouts or blackouts that are scheduled in the future for this target.
If such blackouts exist, then:
From the Grid Control Console, stop all currently running blackouts on all targets monitored by that Management Agent.
From the Grid Control Console, stop all scheduled blackouts on all targets monitored by that Management Agent.
Once you have stopped all currently running and scheduled blackouts, you can run the emctl resetTZ agent command to change the Management Agent's time zone.Once you have changed the Management Agent's time zone, create new blackouts on the targets as needed.
If you are running a Management Agent Release 10.2, then you can use the following command to perform an immediate reevaluation of a metric collection:
emctl control agent runCollection <targetName>:<targetType> <colletionItemName>
where <collectionItemName> is the name of the Collection Item that collects the metric.
Performing this command causes the reevaluated value of the metric to be uploaded into the Management Repository, and possibly trigger alerts if the metric crosses its threshold.
Related metrics are typically collected together; collectively a set of metrics collected together is called a Metric Collection. Each Metric Collection has its own name. If you want to reevaluate a metric, you first need to determine the name of the Metric Collection to which it belongs, then the CollectionItem for that Metric Collection.
When you run the previous command to reevaluate the metric, all other metrics that are part of the same Metric Collection and Collection Item will also be reevaluated.
Perform the following steps to determine the Metric Collection name and Collection Item name for a metric:
Go to $ORACLE_HOME/sysman/admin/metadata directory, where $ORACLE_HOME is the Oracle Home of the Management Agent.
Locate the XML file for the target type. For example, if you are interested in the host metric 'Filesystem Space Available(%)' metric, look for the host.xml file.
In the xml file, look for the metric in which you are interested. The metric that you are familiar with is actually the display name of the metric. The metric name would be preceded by a tag that started with:
<Label NLSID=
For example, in the host.xml file, the metric 'Filesystem Space Available(%)" would have an entry that looks like this:
<Label NLSID="host_filesys_pctAvailable">Filesystem Space Available (%) </Label>
Once you have located the metric in the xml file, you will notice that its entry is part of a bigger entry that starts with:
<Metric NAME=
Take note of the value defined for "Metric NAME". This is the Metric Collection name. For example, for the 'Filesystem Space Available(%)' metric, the entry would look like this:
<Metric NAME="Filesystems"
So for the 'Filesystem Space Available(%)' metric, the Metric Collection name is 'Filesystems'.
The Collection Item name for this Metric Collection needs to be determined next. Go to the $ORACLE_HOME/sysman/admin/default_collection directory, where $ORACLE_HOME is the Oracle Home of the Management Agent.
In this directory, look for the collection file for the target type. In our example, this would be host.xml.
In cases where a Metric Collection is collected by itself, there would be a single Collection Item of the same name in the collection file. To determine if this is the case for your Metric Collection, look for an entry in the collection file that starts with:
<CollectionItem NAME=
where the value assigned to the CollectionItem NAME matches the Metric NAME in step (4).
For the 'Filesystem Space Available(%)' metric, the entry in the collection file would look like:
<CollectionItem NAME = "Filesystems"
If you find such an entry, then the value assigned to "CollectionItem NAME" is the collection item name that you can use in the emctl command.
Otherwise, this means the Metric Collection is collected with other Metric Collections under a single Collection Item. To find the Collection Item for your Metric Collection, first search for your Metric Collection. It should be preceded by the tag:
<MetricColl NAME=
Once you have located it, look in the file above it for: <CollectionItem NAME=
The value associated with the CollectionItem NAME is the name of the collection item that you should use in the emctl command.
For example if the you want to reevaluate the host metric "Open Ports", using the previous steps, you would do the following:
Go to the $ORACLE_HOME/sysman/admin/metadata directory where $ORACLE_HOME is the Oracle Home of the Management Agent. Look for the host.xml file and in that file locate: <Metric NAME="openPorts".
Then go to the $ORACLE_HOME/sysman/admin/default_collection directory. Look for the host.xml file and in that file look for <CollectionItem NAME="openPorts".
Failing this, look for <MetricColl NAME="openPorts".
Look above this entry in the file to find the <CollectionItem NAME= string and find <CollectionItem NAME="oracle_security".
The CollectionItem NAME oracle_security is what you would use in the emctl command to reevaluate the Open Ports metric.

The emctl.log file is a file that captures the results of all emctl commands you run. The log file resides in the $ORACLE_HOME/sysman/log directory of the Management Agent, and is updated every time you run an emctl command. If your emctl command fails for some reason, access this log file to diagnose the issue.
For example, run the following command from the Oracle home directory of the Management Agent to check its status:
<Oracle_Home>emctl status agent
After running the command, navigate to the log directory to view the following information in the emctl.log file:
1114306 :: Wed Jun 10 02:29:36 2009::AgentLifeCycle.pm: Processing status agent 1114306 :: Wed Jun 10 02:29:36 2009::AgentStatus.pm:Processing status agent 1114306 :: Wed Jun 10 02:29:37 2009::AgentStatus.pm:emdctl status returned 3
Here, the first column, that is, 1114306, is the thread that was used to check the status. The second column shows the date and time when the command was run. The third column mentions the Perl script that was run for the command. The last column describes the result of the command, where it shows the progress made by the command and the exit code returned for the command. In this case, the exit code is 3, which means that the Management Agent is up and running.
Another example, run the following command from the Oracle home directory of the Management Agent to upload data:
<Oracle_Home>emctl upload agent
After running the command, navigate to the log directory to view the following information in the emctl.log file:
1286220 :: Tue Jun 9 07:13:09 2009::AgentStatus.pm:Processing upload 1286220 :: Tue Jun 9 07:13:10 2009::AgentStatus.pm:emdctl status agent returned 3 1286220 :: Tue Jun 9 07:13:41 2009::AgentStatus.pm: emdctl upload returned with exit code 6
Here, the entries are similar to the entries in the first example, but the exit code returned is 6, which means the upload operation is failing for some reason.
Table 7-9 describes the different exit codes of an emctl command:
| Exit Code | Description |
|---|---|
|
0 |
Operation was successful. No action required from user. |
|
1 |
Failed to connect to the Management Agent. Maybe the Management Agent is not running. Restart the Management Agent, and then try the emctl command again. |
|
2 |
Timed out while connecting to the Management Agent. Maybe the Management Agent is hanging. Restart the Management Agent, and then try the emctl command again. |
|
3 |
Management Agent is up and running. No action required from user. |
|
4 |
Management Agent is up but not ready. Wait for some more time, and then try the emctl command again. |
|
5 |
Input/output error while sending Management Agent-related request or receiving Management Agent-related response. |
|
6 |
Unable to upload. Check the status of the Management Agent, and then try the emctl command again. |
|
7 |
Management Agent is in an abnormal state. Check the status of the Management Agent, and then try the emctl command again. |
|
8 |
Operation was incomplete. The command might have timed out. Try again. |
|
9 |
Usage error. Check the command you are running and try again with the correct command. |
|
10 |
SSL handshake error while communicating with the Management Agent. Secure the Management Agent, and then try the emctl command again. |
|
11 |
Key mismatch while communicating with the Management Agent. Secure the Management Agent, and then try the emctl command again. |
|
255 |
Unable to open the temporary file. Try the emctl command again. |
