E Disaster Recovery for Collocated Infrastructure Deployments

E.1 Setting Up Disaster Recovery for Infrastructure Deployments with Collocated Identity Management and Metadata Repository

The steps in this section are for an Identity Management deployment which has Oracle Internet Directory and the OracleAS Metadata Repository collocated in one Oracle home and Single Sign-On Server installed in another Oracle home.

The steps below assume that the proper host names, ports, and other configuration described in Chapter 2, "Implementing the Solution" have been set up for the production site and standby site.

Follow these steps to set up Disaster Recovery for this deployment:

1. Use a remote copy mechanism such as rcp to copy the Oracle Internet Directory Oracle home from the production site host to the peer standby site host. A variation of this is to not include the data files in the copy operation to reduce the copy time. See the step below about RMAN.

2. Perform an RMAN backup of the production site Infrastructure database (which includes Oracle Internet Directory and which is in the Oracle Internet Directory Oracle home) and apply it to the standby site Infrastructure database. This is a one time operation.

3. Set up Oracle Data Guard for the Infrastructure (Oracle Internet Directory) database. See Appendix A, "Using Databases in the OracleAS Disaster Recovery Solution" for more information about setting up Oracle Data Guard.

4. Exclude the Infrastructure (Oracle Internet Directory) Oracle home from any future peer to peer file copy operations. Oracle Data Guard is synchronizing this database for the production and standby sites.

5. Use disk replication for the other Oracle homes (for this example, the Single Sign-On Server Oracle home) on a periodic basis.
