Scaling Up the Directory Tier

Managing Enterprise Deployments 20-11

20.3.1 Scaling Up the Topology

The Oracle Identity Management topology described in the guide has three tiers: the directory tier, application tier and web tier. The components in all the three tiers can be scaled up by adding a new server instance to a node that already has one or more server instances running. The procedures described in this section show you how to create a new managed server or directory instance. If you add a new managed server, after adding the managed server you must update your Oracle HTTP Server configuration files on all nodes and add the new server to the existing WebLogic cluster directives. For example if you add a new Oracle Access Manager server, you must update oam.conf to include the new managed server. Update oam.conf as follows: Location oam SetHandler weblogic-handler WebLogicCluster idmhost1.mycompany.com:14100,idmhost2.mycompany.com:14100,idmhost3.mycompany.com:1 4100 Location Once you have updated oam.conf, restart the Oracle HTTP servers as described in Section 20.1, Starting and Stopping Oracle Identity Management Components. Oracle recommends that you do this sequentially to prevent loss of service.

20.3.1.1 Scaling Up the Directory Tier

The directory tier consists of the two Oracle Internet Directory nodes OIDHOST1 and OIDHOST2, each running an Oracle Internet Directory instance and the two Oracle Virtual Directory nodes OVDHOST1 and OVDHOST2, each running an Oracle Virtual Directory instance. The Oracle Internet Directory or Oracle Virtual Directory instances can be scaled up on one or both the nodes.

20.3.1.1.1 Scaling Up Oracle Internet Directory The directory tier has two Oracle Internet

Directory nodes OIDHOST1 and OIDHOST2, each running an Oracle Internet Directory instance. The existing Oracle Identity Management binaries on either node can be used for creating the new Oracle Internet Directory instance. To add a new Oracle Internet Directory instance to either Oracle Internet Directory node, follow the steps in Section 7.3.2, Configuring an Additional Oracle Internet Directory Instance with the following variations: 1. In step 2 and step 4, choose ports other than 389 and 636 since these ports are being used by the existing Oracle Internet Directory instance on the node. 2. Follow the steps in Section 7.4.1, Registering Oracle Internet Directory with the WebLogic Server Domain to register the new Oracle Internet Directory instance with the WebLogic domain. Use the location for the new Oracle Internet Directory instance as the value for ORACLE_INSTANCE. 3. Reconfigure the load balancer with the host and port information of the new Oracle Internet Directory instance. 4. If you have enabled Single Sign-on in the topology, you must update the WebTier configuration for Single Sign-on as described in Section 19.5, Installing and Configuring WebGate. 5. Register the new Oracle HTTP Server instance as described in Section 6.10, Registering Oracle HTTP Server with WebLogic Server. 20-12 Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity Management

20.3.1.1.2 Scaling Up Oracle Virtual Directory The directory tier has two nodes

OVDHOST1 and OVDHOST2, each running an Oracle Virtual Directory instance. The existing Oracle Identity Management binaries on either node can be used for creating the new Oracle Virtual Directory instance. To add a new Oracle Virtual Directory instance to either Oracle Virtual Directory node, follow the steps in Section 9.3.2, Configuring an Additional Oracle Virtual Directory with the following variations: 1. In step 2 and step 4, choose ports other than 6501 and 7501 since these ports are being used by the existing Oracle Virtual Directory instance on the node. 2. Follow the steps in these sections to register the new Oracle Virtual Directory instance with the WebLogic domain. Use the location for the new Oracle Virtual Directory instance as the value for ORACLE_INSTANCE. ■ Section 9.4, Post-Configuration Steps ■ Section 9.6, Validating the Oracle Virtual Directory Instances ■ Section 9.7, Creating ODSM Connections to Oracle Virtual Directory ■ Section 9.8, Creating Adapters in Oracle Virtual Directory ■ Section 10.4.9, Updating Oracle Virtual Directory Adapters 3. Reconfigure the load balancer with the host and port information of the new Oracle Virtual Directory instance.
