DBRSE= parameter for procedures
Use the DBRSE= parameter in procedure to specify the 8-character RSENAME.
It is used by a primary and an alternate DBCTL region
in a DBCTL standby
configuration, and it must be the same in both DBCTL regions.
A cold start is required for any change to this parameter to take effect.
