4. Select None for Hostname Verification.

5. Click Save.

6. Click Activate Changes in the Change Center of the Administration Console.

7. Restart all servers. If the Managed Server is started in Admin mode, perform these steps: 1. If you have not already done so, in the Change Center of the Administration Console, click Lock Edit.

2. In the left pane of the Console, expand Servers and the name of the server that is

running in ADMIN mode.

3. Select the Control StartStop tab.

4. Select the name of the server.

5. Click Resume.

6. Select Yes to resume servers.

If WebLogic Node Manager fails to start, ensure that you copied the following domains file from IDMHOST1 to IDMHOST2: WL_HOME commonnodemanagernodemanager.domains

8.6.6.3 Oracle Directory Services Manager Failover Using Oracle HTTP Server is Not Transparent

When you perform an Oracle Directory Services Manager failover using Oracle HTTP Server, the failover is not transparent. You will see this behavior when you perform the following steps:

1. Oracle Directory Services Manager is deployed in a high availability active-active

configuration using Oracle HTTP Server.

2. Open an Oracle Directory Services Manager page using the Oracle HTTP Server

name and port number. 3. Make a connection to an LDAP server, for example, an Oracle Internet Directory server or an Oracle Virtual Directory server. 4. Work with the LDAP server using the current Oracle Directory Services Manager Oracle HTTP Server host and port. 5. Shut down one Managed Server at a time using the Oracle WebLogic Server Administration Console. 6. Go back to the Oracle Directory Services Manager page and port, and the connection which was established earlier with Oracle Internet Directory or Oracle Virtual Directory. When you do, a message is displayed advising you to reestablish a new connection to the Oracle Directory Services Manager page. In this situation, you must do the following: 1. In your web browser, exit the current Oracle Directory Services Manager page. 2. Launch a new web browser page and specify the same Oracle Directory Services Manager Oracle HTTP Server name and port. 8-106 Oracle Fusion Middleware High Availability Guide 3. Reestablish a new connection to the LDAP server you were working with earlier Oracle Internet Directory or Oracle Virtual Directory. 8.6.6.4 Oracle Directory Services Manager Displays LDAP Server is down Message During Oracle Internet Directory Failover In a high availability configuration where Oracle Directory Services Manager is connected to Oracle Internet Directory through a load balancer, Oracle Directory Services Manager opens the LDAP Server is down message during failover from one instance of Oracle Internet Directory to another. The connection reestablishes less than a minute after the Oracle Internet Directory failover is complete and you can continue without logging in again. 8.6.6.5 Oracle Directory Services Manager Temporarily Loses Its Connection During Oracle RAC Failover Oracle Directory Services Manager temporarily loses its connection to an Oracle Internet Directory instance that is using an Oracle RAC database during an Oracle RAC failover. Oracle Directory Services Manager may display the message Failure accessing Oracle database oracle errcode=errcode, where errcode is one of the following values: 3113, 3114, 1092, 28, 1041, or 1012. The connection will be reestablished in less than a minute after the Oracle RAC failover is complete, and you will be able to continue without logging in again.

8.6.7 Additional Considerations for Oracle Directory Services Manager High Availability

When using Oracle Directory Services Manager to manage an Oracle Internet Directory cluster, use the load balancer virtual address as the connect string. However, when using Oracle Directory Services Manager to manage an Oracle Virtual Directory cluster, you must specify the host name and port for a specific Oracle Virtual Directory instance.

8.7 Collocated Architecture High Availability

This section describes how to design and deploy Oracle Internet Directory, Oracle Directory Integration Platform, Oracle Virtual Directory, and Oracle Directory Services Manager in collocated high availability environments. The introduction to these components is provided in previous sections of this manual. This section describes the collocated architecture for Oracle Internet Directory, Oracle Directory Integration Platform, Oracle Virtual Directory and Oracle Directory Services Manager when deployed in a high availability configuration. This section includes the following topics: ■ Section 8.7.1, Collocated Architecture Overview ■ Section 8.7.2, Collocated Architecture High Availability Deployment ■ Section 8.7.3, Validating the Collocated Components High Availability ■ Section 8.7.4, Troubleshooting Collocated Components Manager High Availability ■ Section 8.7.5, Additional Considerations for Collocated Components High Availability
