Task 10: Configure Fusion Middleware Control to Monitor the Upgraded Components

16 Performing an Oracle Identity Management Multimaster and Fan-Out Replication Upgrade 16-1 16 Performing an Oracle Identity Management Multimaster and Fan-Out Replication Upgrade This appendix describes how to upgrade to Oracle Identity Management 11g Release 1 11.1.1 in an Oracle Internet Directory replicated environment. Refer to the following sections for more information: ■ Task 1: Review the Terminology, Prerequisites, and Key Concepts For Upgrading a Replication Environment ■ Task 2: Prepare for the Oracle Identity Management Multimaster or Fan-Out Replication Upgrade ■ Task 3: Perform the Oracle Internet Directory Replica Upgrade ■ Task 4: Completing the Upgrade of Each Replica 16.1 Task 1: Review the Terminology, Prerequisites, and Key Concepts For Upgrading a Replication Environment Review the following prerequisites and requirements before proceeding with the upgrade procedures in this chapter: ■ Terminology Conventions for This Chapter ■ Valid Starting Points When Upgrading a Replication Environment ■ Oracle Recommendations When Upgrading a Replication Environment

16.1.1 Terminology Conventions for This Chapter

In this chapter, the destination replica is the newly installed and upgraded 11g Release 1 11.1.1 replica; the source replica is the 10g Release 2 10.1.2 or 10g 10.1.4.0.1 replica you are upgrading.

16.1.2 Valid Starting Points When Upgrading a Replication Environment

The upgrade procedures in this chapter are designed for administrators who have installed and configured an Oracle Internet Directory 10g Release 2 10.1.2 or 10g 10.1.4.0.1 multimaster or fan-out replication environment. This chapter assumes that the Oracle Identity Management components in the replication environment are distributed. In other words, you have installed the Oracle Internet Directory and optionally Oracle Directory Integration Platform components 16-2 Oracle Fusion Middleware Upgrade Guide for Oracle Identity Management in one or more Oracle homes, and you installed the Oracle Single Sign-On and Oracle Delegated Administration Services components in one or more additional Oracle homes. Figure 16–1 shows a typical Oracle Identity Management 10g Release 2 10.1.2 multimaster replication environment, which is described in detail in Deploying Identity Management with Multimaster Replication, in the 10g Release 2 10.1.2 Oracle Fusion Middleware High Availability Guide. Figure 16–1 A Typical Oracle Identity Management 10g Release 2 10.1.2 Multimaster Replication Environment Information about deploying Oracle Identity Management with fan-out replication can be found in the Oracle Application Server 10g 10.1.4.0.1 Oracle Identity Management Concepts and Deployment Planning Guide, which is available in the Oracle Application Server 10g Release 2 10.1.2 documentation library.

16.1.3 Oracle Recommendations When Upgrading a Replication Environment

Oracle Corporation recommends the following during the upgrade procedure: ■ After you upgrade the destination replica, disable replication between the destination replica and the source replica. The destination replica can receive and process changes from source replica, but the source replica cannot process changes originated and received from destination replica.

16.2 Task 2: Prepare for the Oracle Identity Management Multimaster or Fan-Out Replication Upgrade

Before you begin upgrading Oracle Internet Directory in a replicated environment, you must perform the following steps for all replicas other than Master Definition Site MDS Replica or Primary supplier replica: 1. Locate the database registration entry of the database of replica to be upgraded. On Window systems: SOURCE_ORACLE_HOME \bin\ldapsearch -h hostname_of_replica_being_upgraded -p port -D cn=orcladmin -w superuser_password -b cn=oraclecontext -s one objectclass=orcldbserver dn On UNIX systems: SOURCE_ORACLE_HOME binldapsearch -h hostname_of_replica_being_upgraded -p port -D cn=orcladmin -w superuser_password -b cn=oraclecontext -s one objectclass=orcldbserver dn This will return a list of Distinguished Names DNs corresponding to all the Databases registered in Oracle Internet Directory in the following form: cn=database_name,cn=oraclecontext From the returned list of entries, locate and make a note of the DN of the following entry, which corresponds to the replica upgraded: cn=dbname_of_replica_to_be_upgraded,cn=oraclecontext 2. Identify the replica ID of the replica to be upgraded by issuing following command: On Windows systems: SOURCE_ORACLE_HOME \bin\ldapsearch -h hostname_of_replica_being_upgraded -p port -D cn=orcladmin -w superuser_password -b -s base objectclass= orclreplicaid On UNIX systems: SOURCE_ORACLE_HOME binldapsearch -h hostname_of_replica_being_upgraded -p port -D cn=orcladmin -w superuser_password -b
