Requirements
Installing Oracle Internet Directory in Replicated Mode 6-3
Figure 6–2 Example of Multimaster Replication (Advanced Replication)
In multimaster replication, Oracle Internet Directory instances use the Oracle Database
Advanced Replication protocol to communicate with each other. The Select Oracle
Internet Directory Replication Mode screen in the installer uses the term Advanced
Replication
to refer to multimaster replication.
The procedure for installing a master Oracle Internet Directory is the same as installing
a "regular" (non-replicated) Oracle Internet Directory.
The procedure for installing replicas is different. When installing a replica, you must
select the High Availability and Replication option in the Select Configuration
Options screen, and you need to provide connect information to the master Oracle
Internet Directory.
The Oracle Application Server instance that runs the Oracle Internet Directory (master
or replica) can also run other Oracle Application Server components, such as the
OracleAS Metadata Repository, OracleAS Single Sign-On, Oracle Delegated
Administration Services, and/or Oracle Directory Integration Platform.
6.2 Requirements
Check that you meet the following requirements for installing Oracle Internet
Directory in replication mode:
■
Section 6.2.1, "Database Requirements"
■
Section 6.2.2, "Clock Synchronization"
6.2.1 Database Requirements
Each Oracle Internet Directory, whether master or replica, needs its own OracleAS
Metadata Repository. You can install it with a new OracleAS Metadata Repository, or
against an existing OracleAS Metadata Repository.
If installing against an existing OracleAS Metadata Repository, you can create an
existing OracleAS Metadata Repository in two different ways:
■
You can install it by selecting the OracleAS Metadata Repository option in the
Select Installation Type screen.
■
You can install the OracleAS Metadata Repository in an existing database. See the
Oracle Application Server Metadata Repository Creation Assistant User’s Guide for
details on how to load the OracleAS Metadata Repository in an existing database.
