Changing the QNAME List

The first system active in a complex is the system that reads the MIMQNAME parameter member and builds the QNAME list for the entire complex. The second through nth systems activated in the complex have the QNAME list passed to them during synchronization, and the contents of the MIMQNAME member are ignored with respect to the QNAME list already in use by the complex. This implies that changing the MIMQNAME parameter member results in changing the QNAME list in use by the complex only if accompanied by a global shutdown.

The only way to change the QNAME list in use by an active complex is to use the ADDQNAME, ALTER, and DELQNAME commands. These commands make changes to the active complex dynamically, but their effect is temporary. Changes made with these commands persist until the last instance of CA MII in the complex is shut down.

We recommend the following procedures for making permanent QNAME list changes:

1. Make the desired change to the active complex using the ADDQNAME, ALTER, or DELQNAME commands.
2. Promptly make the corresponding updates in the MIMQNAME member.

   Note: This procedure assumes you have GDIINIT MISMATCHQNAME=ACCEPT specified or defaulted.

-- OR --

1. Make the desired modifications in the MIMQNAME member.
2. Shut down CA MII on all systems in the complex.
3. Restart CA MII on all systems in the complex.
