Recovering from primary CONTROL-M/Server failure (Server failover)

These procedures assume that a failover server has already been installed and initialized on a secondary computer. Two procedures are used during failover situations:

1. Verify that:
• Both primary and secondary CONTROL-M/Server installations and CONTROL-M/Server Configuration Agent are not running.
• Both the primary and mirror database servers are running.
2. Log on to the secondary computer as the CONTROL-M/Server owner.
3. Specify the ctm_menu command to open the CONTROL-M Main Menu.
4. Type 4 to select Database Mirroring and press <Enter>.
5. From the Database Mirroring menu, type 7 to select Start Failover and press <Enter>.

WARNING


Do not start the secondary CONTROL-M/Server while the primary CONTROL-M/Server is running, or before the Start Failover procedure finishes executing. If the secondary CONTROL-M/Server is started too early, the following message may be displayed: 

** Unable to start CONTROL-M due to path specified for PROCLIB directory $PROCLIB. This path is invalid **

6. The following message is displayed:

This operation disables CONTROL-M database mirroring, and starts FailOver CONTROL-M !!!

Confirm that CONTROL-M in the primary data center is not running.Continue [y/n] :

7. Type y and press <Enter> to continue with Failover.

The following message is displayed:
CONTROL-M/Server database mirroring 

Mirroring of the CONTROL-M/Server database allows rapid recovery of CONTROL-M/Server functionality in the event of a failure of the CONTROL-M/Server database. You can implement mirroring during or after CONTROL-M/Server installation.

To implement CONTROL-M/Server database mirroring

1. Review the database requirements for mirroring as described in the CONTROL-M/Server for UNIX and Microsoft Windows Installation Guide. 


2. Verify that CONTROL-M/Server, CONTROL-M/Server Configuration Agent, and CONTROL-M/Server utilities are not running. Ensure that the SQL database is running.


3. Choose Database Mirroring => Initialize Mirroring from the CONTROL-M Main Menu.


4. At the conclusion of the procedure, restart CONTROL-M/Server and the CONTROL-M/Server Configuration Agent
