This chapter describes how to complete the postinstallation tasks after you have installed the Oracle Database 12c Release 1 (12.1) with Oracle Real Application Clusters (Oracle RAC) software. This chapter contains the following topics:
Note:
This chapter describes only basic configurations. See also:Oracle Database Platform Guide for Microsoft Windows and the product administration and tuning guides for more detailed configuration and tuning information
Oracle Database Installation Guide for Microsoft Windows for additional postinstallation configuration information
Perform the following tasks after completing your installation:
Creating the OraMTS Service for Microsoft Transaction Server
Configuring Storage for External Tables, Shared Files, or Directory Objects
If you did not choose to download software options during installation, then after installing Oracle RAC, verify if there are any patches needed for your system. To determine if any patches are required for your system, review the Oracle Database Readme and the Oracle Database Release Notes for Microsoft Windows.
If the Windows Firewall feature is enabled on one or more of the nodes in your cluster, then virtually all TCP network ports are blocked to incoming connections. As a result, any Oracle product that listens for incoming connections on a TCP port does not receive any of those connection requests and the clients making those connection requests report errors.
If the Windows Firewall feature is enabled on one or more nodes of your Oracle RAC cluster, then you must create exceptions for Oracle RAC applications and ports as described in Oracle Grid Infrastructure Installation Guide if you have not done so already.
Oracle Services for Microsoft Transaction Server (OraMTS) permit Oracle databases to be used as resource managers in Microsoft application coordinated transactions. OraMTS acts as a proxy for the Oracle database to the Microsoft Distributed Transaction Coordinator (MSDTC). As a result, OraMTS provides client-side connection pooling and allows client components that leverage Oracle to participate in promotable and distributed transactions. In addition, OraMTS can operate with Oracle databases running on any operating system, given that the services themselves are run on Windows.
On releases earlier than Oracle Database 12c, the OraMTS service was created as part of a software-only installation. Starting with Oracle Database 12c, you must use a configuration tool to create this service.
To create the OraMTS service after performing a software-only installation of Oracle RAC or after adding a node to an existing cluster, perform the following steps:
Open a command window.
Change directories to %ORACLE_HOME%\bin.
Run the OraMTSCtl utility to create the OraMTS Service, where host_name is a list of nodes on which the service should be created:
C:\..bin> oramtsctl.exe -new -host host_name

Before using individual Oracle Database 12c Release 1 (12.1) products or options, refer to the appropriate manual in the product documentation library, which is available on the Oracle Technology Network (OTN) website at:
Refer to these sections for information about configuring various products and features after installation:
OUI installs Oracle Database Vault by default when you install the Oracle RAC software, but you must register Oracle Database Vault with the Oracle RAC database and create database user accounts before you can use it. You must create the Database Vault Owner user and, optionally, the Database Vault Account Manager administrative user accounts.
To enable or disable the database security configuration after installation, you must use command-line Oracle Database Configuration Assistant (DBCA) options. By design, the DBCA graphical user interface (GUI) does not have the option to enable or disable secure configuration. For example, to enable the security settings after installation, you would use a command of the following form, where myRACdb1.example.com is the either the name of the local database instance or the DB_UNIQUE_NAME:
dbca –configureDatabase –sourceDB myRACdb1.example.com -SID –enableSecurityConfiguration true

Oracle Database Installation Guide for Microsoft Windows for more information about enabling and disabling the database security optionAfter installation, you must configure Oracle Label Security in a database before you use it. You can configure Oracle Label Security in two ways: with Oracle Internet Directory integration and without Oracle Internet Directory integration.
| Configuration | Requirements |
|---|---|
| With Oracle Internet Directory integration | To configure Oracle Label Security with Oracle Internet Directory integration, Oracle Internet Directory must be installed in your environment and the Oracle database must be registered in the directory. |
| Without Oracle Internet Directory integration | If you configure Oracle Label Security (OLS) without Oracle Internet Directory integration, then you cannot configure it to use Oracle Internet Directory at a later stage. To configure Oracle Label Security with Oracle Internet Directory on your database at a later time, you must remove the OLS option on the database and configure the OLS with Oracle Internet Directory integration option. |

Oracle Label Security Administrator's Guide for information about configuring Oracle Label SecurityOracle Database Extentions (ODE) for .NET depends on a Windows service to operate properly. This service is called the OraClrAgnt service.
In earlier versions of Oracle Database, this CLR service was created automatically by the installer. Starting with Oracle Database 12c, after installation you use the OracleClrCtl.exe utility to create, start, stop, and delete the OraClrAgnt service. When you use the OraClrCtl.exe utility to create the service, a new service is created named OracleHomenameClrAgent, where Homename represents an Oracle Home name. The OraClrAgnt service is configured by this tool using the Oracle Home User account specified during the Oracle Database installation..

However, you must manually configure the FTP and HTTP ports for Oracle XML DB.
See Also:
Oracle XML DB Developer's Guide for information on configuring the FTP and HTTP protocols for Oracle XML DBRun the utlrp.sql script after creating or upgrading a database. This script recompiles all PL/SQL modules that might be in an invalid state, including packages, procedures, and types. Run the utlrp.sql script immediately following installation, not at a later date.
(Optional) Complete setting up the Oracle Installation User environment, as described in Section 4.2.1, "Setting the Oracle User Environment Variables."
Log in as an Administrator user, or as the Oracle Home user.
Start SQL*Plus, as follows:
Click Start, select Programs (or All Programs), then Oracle - HOME_NAME, then Application Development, and then SQL*Plus.
Login as a SYSDBA user.
Run the utlrp.sql script, where Oracle_home is the Oracle home path:
SQL> @Oracle_home\rdbms\admin\utlrp.sql
If your Oracle RAC database uses files that are external to the database, then the external files should be located on shared storage that is accessible to all nodes. Each node should use the same mount point to access the file. Acceptable shared file systems include Database File System (DBFS), Oracle ASM Cluster File System (Oracle ACFS), or a supported network file system (NFS) using the Direct NFS Client.
The database directory object used to write and read files external to the database must point to a shared storage location, and each node must use the same mount point for the same shared storage location. For example, each node might have a directory object called DPUMP for the mount point C:\app\acfsmounts\dpump, which accesses Oracle ACFS shared storage.
Note:
There is no checking of the contents of the external files or directory object specified as part of the external table to ensure that the directory contents are consistent on each node. To avoid unpredictable results, you must ensure that the same file is accessed from all nodes, or that the same file is used on all nodes.See Also:
Oracle Grid Infrastructure Installation Guide for more information about configuring storageOracle recommends that you complete the following tasks after completing an Oracle RAC installation:
Unlike on other platforms, you should not set ORACLE_HOME as a fixed environment variable when running Oracle Database on Windows operating systems. This is because the Oracle software determines where executable files reside at run time.
When you invoke an Oracle executable program on Windows, for example sqlplus.exe, the ORACLE_HOME, ORACLE_BASE, and ORACLE_SID variables are determined by the PATH environment variable and the location of the executable program (which Oracle home it resides in). To use SQL*Plus to manage a different database or Oracle ASM instance, click the Windows Start button, select the correct Oracle Home for the instance you want to manage, and then select the SQL*Plus utility.
You can use Oracle Universal Installer (OUI) to specify an Oracle home as the default Oracle home and update the PATH environment variable to point to that Oracle home. Refer to Section 6.5, "Working with Multiple Oracle Home Directories on Windows" for detailed instructions on how to change the default Oracle home.
You can set up additional user accounts to manage your database. For information about setting up additional optional user accounts, see Oracle Database Platform Guide for Microsoft Windows and Oracle Database Security Guide.
Oracle Administration Assistant for Windows requires the Microsoft Management Console and HTML Help 1.2 or later to run. Microsoft Management Console (MMC) version 3.0 of MMC is available with Windows Server 2008 and later. Oracle recommends that you use the latest version of MMC that is available.

Under certain circumstances you may have to perform additional configuration steps for the Oracle Home user, such as:
Creating an OCR wallet for Oracle Home user
Changing the password for the Oracle Home user
See the Oracle Database Platform Guide for Microsoft Windows for details on performing these tasks.
If you have installed Oracle Configuration Manager, then you must run a script to create a database account to collect database configuration collections. You must create this account in both Connected and Disconnected modes. The database account stores the PL/SQL procedures that collect the configuration information, and the account owns the database management system (DBMS) job that performs the collection. After the account has been set up, the account is locked because login privileges are no longer required.
To configure the database for configuration collection, run the following script:
The script installCCRSQL.exe creates an Oracle Configuration Manager user and loads the PL/SQL procedure into the database defined by the ORACLE_SID environment variable. You can also specify the database SID by using the -s option in the command line, as in the following example, where the SID is orcl:
For Oracle RAC, you must run the database script against only one instance, such as the local instance on which you performed the installation. However, Oracle Configuration Manager must be installed in all instance homes.

Oracle Database Administrator's Guide for information about connecting to the database using SQL*PlusTo enable or disable a particular database feature for an Oracle home, shut down the database and use the chopt tool. The chopt tool is a command-line utility that is located in the Oracle_home\bin directory. The syntax for chopt is as follows:
chopt [ enable | disable] db_option
Table 4-1 describes the possible values for db_option:
Table 4-1 Database Options for Chopt Tool Command
| Value | Description |

Oracle Data Mining Database Files |
|
|
Oracle OLAP |
|
|
Oracle Partitioning |
|
|
Oracle Real Application Testing |
|
|
Oracle Database Extensions for .NET |
Before you run the chopt tool, shut down any Oracle databases running from the Oracle home being modified.
Example 4-1 How to Enable the Oracle Label Security Database Option Using Chopt
In this example, the chopt tool enables Oracle Label Security in the database oradb1:
Shut down the Oracle RAC database, and any other databases running out of the Oracle home directory, using the Server Control Utility (SRVCTL).
srvctl stop database -db oradb1
Change directories to the Oracle_home\bin directory:
Run the chopt tool, as follows:
chopt enable lbac
Use SRVCTL to restart the databases you stopped in Step 1, for example:
srvctl start database -db oradb1
