Migrating the role of primary site to the secondary site


Migrating the role of primary site to the secondary site
Prev	Using VVR commands on SF Oracle RAC global clusters	Next

After configuring the replication objects within VCS, you can use VCS commands to migrate the role of the cluster on the primary site to the remote cluster. In the procedure below, VCS takes the replicated database service group, database_grp, offline on the primary site and brings it online on the secondary site; the secondary site now assumes the role of the primary site.

Note:

The hagrp -switch command cannot migrate a parallel group within a cluster or between clusters in a global cluster environment.

To migrate the role of primary site to the remote site

From the primary site, use the following command to take the Oracle service group offline on all nodes.
```
# hagrp -offline database_grp -any
			
```
Wait for VCS to take all Oracle service groups offline on the primary site.
Verify that the RLINK between the primary and secondary is up to date. Use the vxrlink -g command with the status option and specify the RLINK for the primary cluster. You can use the command from any node on the primary cluster.

For example:
```
# vxrlink -g data_disk_group status rlk_rac_cluster101_priv_rac1_rvg
			
```
Where rlk_rac_cluster101_priv_rac1_rvg is the RLINK.
On the secondary site, which is now the new primary site, bring the Oracle service group online on all nodes:
```
  # hagrp -online database_grp -any
			
```
