Start-up in Failover Mode

This section contains recommendations for UVMS start-up in failover.

In failover mode, only one UVMS can be started at a time. A configuration can be implemented to verify upon start-up of a UVMS that no other instance in the failover is already started. If a UVMS instance is already started, all new start-ups are refused.

The database should not support other products.

To activate this configuration, the UVMS node setting ADV_ARCH_ENABLE_CHECK_DB_CONFLICTS must be set to "Y".

This configuration is based on the lock verification for a database table. This verification requires the read right for the external database processes and is therefore not activated by default.

The following scripts can be run by a database administrator:

SQL script to give the right:

MS SQL SERVER: grant VIEW SERVER STATE to <user>;

ORACLE:        grant select on v_$session to <user>;

SQL script to take off the right:

MS SQL SERVER: revoke VIEW SERVER STATE from <user>;

ORACLE:        revoke select on v_$session from <user>;

As of version 6.10.41, documentation new updates are posted on the Broadcom Techdocs Portal.
