This chapter describes how to extend the domain with Oracle Internet Directory (OID) in the enterprise deployment.
This chapter includes the following topics:
Section 7.1, "Prerequisites for Configuring Oracle Identity Directory Instances"
Section 7.2, "Configuring the Oracle Internet Directory Instances"
Section 7.3, "Post-Configuration Steps"
Section 7.4, "Validating the Oracle Internet Directory Instances"
Section 7.5, "Backing up the OID Configuration"
Before configuring the Oracle Internet Directory instances on OIDHOST1 and OIDHOST2, ensure that the following tasks have been performed:
Synchronize the time on Oracle Internet Directory, as described in Section 7.1.1.
Install and upgrade the software on OIDHOST1 and OIDHOST2 as described in Section 4.5.4 and Section 4.6.1.
If you plan on provisioning the Oracle Internet Directory instances on shared storage, ensure that the appropriate shared storage volumes are mounted on OIDHOST1 and OIDHOST2 as described in Section 2.4.
Make sure that the load balancer is configured.
Before setting up Oracle Internet Directory in a high availability environment, you must ensure that the time on the individual Oracle Internet Directory nodes is synchronized.
Synchronize the time on all nodes using Greenwich Mean Time so that there is a discrepancy of no more than 250 seconds between them.
If OID Monitor detects a time discrepancy of more than 250 seconds between the two nodes, the OID Monitor on the node that is behind stops all servers on its node. To correct this problem, synchronize the time on the node that is behind in time. The OID Monitor automatically detects the change in the system time and starts the Oracle Internet Directory servers on its node.
Follow these steps to configure the Oracle Internet Directory components, OIDHOST1 and OIDHOST2 on the directory tier with Oracle Internet Directory. The procedures for the installations are very similar, but the selections in the configuration options screen differ.
This section contains the following topics:
Section 7.2.1, "Configure the First Oracle Internet Directory Instance"
Section 7.2.2, "Configuring an Additional Oracle Internet Directory Instance"
Ensure that ports 389 and 636 are not in use by any service on the computer by issuing these commands for the operating system you are using. If a port is not in use, no output is returned from the command.
On UNIX:
netstat -an | grep "389" netstat -an | grep "636"
If the ports are in use (that is, if the command returns output identifying either port), you must free the port.
On UNIX:
Remove the entries for ports 389 and 636 in the /etc/services file and restart the services, as described in Section 19.1, "Starting and Stopping Oracle Identity Management Components,"or restart the computer.
Copy the staticports.ini file from the Disk1/stage/Response directory to a temporary directory.

Note:
See the "Configuring Your Environment" section of Oracle Fusion Middleware Reference for Oracle Identity Management for a list of the environment variables you must set before using the ldapbind command.Follow the steps in this section to complete the configuration of the Oracle Internet Directory instances on OIDHOST1 and OIDHOST2.
All the Oracle Fusion Middleware components deployed in this enterprise deployment are managed by using Oracle Enterprise Manager Fusion Middleware Control. To manage the Oracle Internet Directory component with this tool, you must register the component and the Oracle Fusion Middleware instance that contains it with an Oracle WebLogic Server domain. A component can be registered either at install time or post-install. A previously un-registered component can be registered with a WebLogic domain by using the opmnctl registerinstance command.
To register the Oracle Internet Directory instances installed on OIDHOST1 and OIDHOST2, follow these steps:
Set the ORACLE_HOME variable. For example, on OIDHOST1 and OIDHOST2, issue this command:
export ORACLE_HOME=/u01/app/oracle/product/fmw/idm
Set the ORACLE_INSTANCE variable. For example:
On OIDHOST1, issue this command:
export ORACLE_INSTANCE=/u01/app/oracle/admin/oid_inst1
On OIDHOST2, issue this command:
export ORACLE_INSTANCE=/u01/app/oracle/admin/oid_inst2
Execute the opmnctl registerinstance command on both OIDHOST1 and OIDHOST2:
ORACLE_INSTANCE/bin/opmnctl registerinstance -adminHost WLSHostName -adminPort WLSPort -adminUsername adminUserName
For example, on OIDHOST1 and OIDHOST2:
ORACLE_INSTANCE/bin/opmnctl registerinstance \
-adminHost idmhost1.mycompany.com-adminPort 7001 -adminUsername weblogic
The command requires login to WebLogic admin server (idmhost1.mycompany.com)
Username: weblogic
Password: *******
Note:
For additional details on registering Oracle Internet Directory components with a WebLogic Server domain, see the "Registering an Oracle Instance or Component with the WebLogic Server" section in Oracle Fusion Middleware Administrator's Guide for Oracle Internet Directory.Update the Enterprise Manager Repository URL using the emctl utility with the switchOMS flag. The emctl utility is located under the ORACLE_INSTANCE/EMAGENT/EMAGENT/bin directory.
Syntax:
./emctl switchOMS <ReposURL>.
For Example:
./emctl switchOMS http://idmhost-vip.mycompany.com:7001/em/upload
Output:
./emctl switchOMS http://idmhost-vip.mycompany.com:7001/em/upload Oracle Enterprise Manager 10g Release 5 Grid Control 10.2.0.5.0. Copyright (c) 1996, 2009 Oracle Corporation. All rights reserved. SwitchOMS succeeded.
Validate if the agents on OIDHOST1 and OIDHOST2 are configured properly to monitor their respective targets. Follow these steps to complete this task:
Use a web browser to access Oracle Enterprise Manager Fusion Middleware Control at http://ADMINVHN.mycompany.com:7001/em.
Log in as the weblogic user.
From the Domain Home Page navigate to the Agent-Monitored Targets page using the menu under Farm -> Agent-Monitored Targets.
Validate that the hostname in Agent URL under the Agent column matches the hostname under the Host column. In case of a mismatch, follow the steps below to correct the issue:
Click the configure link to bring up the Configure Target Page.
On the Configure Target Page, click Change Agent and choose the correct agent for the host.
Click OK to save your changes.
To validate the OID instances, ensure that you can connect to each Oracle Internet Directory instance and the load balancing router using these commands:
Note:
See the "Configuring Your Environment" section of Oracle Fusion Middleware Reference for Oracle Identity Management for a list of the environment variables you must set before using the ldapbind command.ldapbind -h oidhost1.mycompany.com -p 389 -D "cn=orcladmin" -q ldapbind -h oidhost1.mycompany.com -p 636 -D "cn=orcladmin" -q -U 1 ldapbind -h oidhost2.mycompany.com -p 389 -D "cn=orcladmin" -q ldapbind -h oidhost2.mycompany.com -p 636 -D "cn=orcladmin" -q -U 1 ldapbind -h oid.mycompany.com -p 389 -D "cn=orcladmin" -q ldapbind -h oid.mycompany.com -p 636 -D "cn=orcladmin" -q -U 1
Note:
The-q option above prompts the user for a password. LDAP tools have been modified to disable the options -w password and -P password when the environment variable LDAP_PASSWORD_PROMPTONLY is set to TRUE or 1. Use this feature whenever possible.It is an Oracle best practices recommendation to create a backup file after successfully completing the installation and configuration of each tier or at a logical point. Create a backup of the installation after verifying that the install so far is successful. This is a quick backup for the express purpose of immediate restoration in case of problems in later steps. The backup destination is the local disk. This backup can be discarded once the enterprise deployment setup is complete. After the enterprise deployment setup is complete, the regular deployment-specific Backup and Recovery process can be initiated. More details are described in the Oracle Fusion Middleware Administrator's Guide.
For information on database backups, refer to Oracle Database Backup and Recovery Advanced User's Guide.
To back up the installation to this point, follow these steps:
Back up the OID instances in the directory tier:
Shut down the instance using opmnctl located under the ORACLE_INSTANCE/bin directory:
ORACLE_INSTANCE/bin/opmnctl stopall
Create a backup of the Middleware home on the directory tier as the root user:
tar -cvpf BACKUP_LOCATION/dirtier.tar MW_HOME
Create a backup of the Instance home on the directory tier as the root user:
tar -cvpf BACKUP_LOCATION/instance_backup.tar ORACLE_INSTANCE
Start up the instance using opmnctl located under the ORACLE_INSTANCE/bin directory:
ORACLE_INSTANCE/bin/opmnctl startall
Perform a full database backup (either a hot or cold backup). Oracle recommends that you use Oracle Recovery Manager. You can use an operating system tool such as tar for cold backups.
Back up the Administration Server domain directory. This saves your domain configuration. The configuration files all exist under the ORACLE_BASE/admin/domainName/aserver directory:
IDMHOST1> tar cvf edgdomainback.tar ORACLE_BASE/admin/domainName/aserver
Note:
Create backups on all machines in the directory tier by following the steps shown in this section.For more information about backing up the directory tier configuration, see Section 19.4, "Performing Backups and Recoveries."
