10.3.2.1 Adding a Node in Oracle Advanced Database Multimaster Replication

The detailed steps for adding a node in an Oracle Advanced Database multimaster replication deployment are in the Adding a Node for Oracle Database Advanced Replication-Based Multimaster Replication Group section in Oracle Fusion Middleware Administrators Guide for Oracle Internet Directory. Table 10–1 Steps for Setting Up Oracle Database Advanced Multimaster Replication Subsection Instructions Task 1: Install Oracle Internet Directory on the Master Definition Site MDS This task should already have been performed based on the Note in Section 10.3, Setting up Multimaster Replication. Task 2: Install the Oracle Internet Directory on the Remote Master Sites RMS This task should already have been performed based on the Note in Section 10.3, Setting up Multimaster Replication. If an Existing Master is Used as a Remote Master Site Set up one site as the master definition site MDS, for example, the New York site. Then set up one Oracle Internet Directory node in the cluster at the master site for example, OIDHOST1 to be the master host. OIDHOST1 will be the host in the master site cluster where the replication server will be configured and will run. When the setup steps require a reference to a replication server, process, or port for the MDS, specify the correct value for OIDHOST1. Set up another site as the remote master site RMS, for example, the Los Angeles site. Then set up one Oracle Internet Directory node in the cluster at the remote site for example, OIDHOST3 to be the replica host. The replica host is referred to as the new node in the If an Existing Master is Used as a Remote Master Site section. OIDHOST3 will be the host in the Los Angeles cluster where the replication server will be configured and will run. When the setup steps require a reference to a replication server, process, or port for the RMS, specify the correct value for OIDHOST3. Task 3: Set Up Advanced Replication for a Directory Replication Group Follow the instructions for this task. On All Nodes, Prepare the Oracle Net Services Environment for Replication Perform the steps in this subsection in all the database Oracle homes and in all the Oracle Internet Directory Oracle homes in the New York site and the Los Angeles site. From the MDS, Configure Advanced Replication For Directory Replication Perform the steps in this subsection in all of the Oracle Internet Directory Oracle homes in New York and Los Angeles, with one exception: When you configure Advanced Replication using the Replication Environment Management Tool, execute the command on only the master host at the MDS site for example, on OIDHOST1 in New York. The replication must be started on only one Oracle Internet Directory host. Task 4 Optional: Load Data into the Directory If you choose to use the bulkload utility, stop all the Oracle Internet Directory instances in all the Oracle Internet Directory homes, and use only one of the Oracle Internet Directory instances to perform the bulkload operation. Task 5: Ensure that Oracle Directory Server Instances are Started on All the Nodes Perform this task in all the Oracle Internet Directory Oracle home directories. Task 6: Start the Replication Servers on All Nodes in the DRG Start the replication server on only OIDHOST1 in New York and OIDHOST3 in Los Angeles. 10-8 Oracle Fusion Middleware High Availability Guide Table 10–2 shows the subsections of the Adding a Node for Oracle Database Advanced Replication-Based Multimaster Replication Group section in Oracle Fusion Middleware Administrators Guide for Oracle Internet Directory. It also describes the instructions to perform in each subsection to add a node to the maximum high availability Oracle Internet Directory deployment shown in Figure 10–1 .
