Upgrading Control-M in a Disaster Recovery configuration

This procedure describes how to upgrade Control-M/EM and Control-M/Server in a Disaster Recovery configuration on UNIX and Windows. In a disaster recovery environment, the database in the recovery site is set to read-only, which enables replication from the primary site. This procedure allows you to upgrade without changing the read-only status of the database and without interrupting the database replication.

The database in the disaster recovery environment must have read access.

To upgrade Control-M in a Disaster Recovery configuration:

1. Set the inst_skip_db_changes environment variable to Y where the upgrade is executed.
2. Do one of the following:
   • To upgrade Control-M/EM, see Upgrading Control-M/EM on UNIX or Upgrading Control-M/EM on Windows.
   • To upgrade Control-M/Server, see Upgrading Control-M/Server on UNIX or Upgrading Control-M/Server on Windows.
3. Set the inst_skip_db_changes environment variable to N.
