To configure SADTA:
1. Create two CRS sub-clusters; one at the Site A and the other at the Site B.
2. Install the Oracle Clusterware software at each site in the Metrocluster.
3. Configure the CRS daemons at the sub-clusters as a Serviceguard package using SGeRAC
toolkit.
4. Install CRS Home on a file system that is local to a site.
NOTE: The CRS voting and OCR disks must not be configured for replication.
Table 16 lists the CRS packages and other resources that form the CRS sub-cluster at each site.
