Installation of CICS resources

You can use Business Application Services (BAS) to install CICS resources. As with CICS® itself, CICSPlex® SM can install resources either automatically at system initialization time or dynamically into an active system.

CICS regions can be running different releases of CICS, but not all resources are available on all levels of CICS regions; for details, see the individual descriptions of the resource definition objects. The installation facility uses the EXEC CICS CREATE command to create resources independently of the CSD.

When you use CICSPlex SM to install CICS resources, those resources can replace any identical resources that might exist in the system.
Note:
  1. If you are using BAS to install resources automatically when a CICS system initializes, you should specify the CICSPlex SM system parameter MASPLTWAIT(YES) for that system. This parameter suspends PLT processing until all CICS resources are installed and the MAS is fully initialized. For information on specifying this parameter, see Preparing an MVS MAS .
  2. There are special considerations when arranging for activation of a DB2® connection via a DB2 connection definition (DB2CDEF object). For details, see Activating DB2 connections during CICS startup.
  3. It is not possible to use BAS to install a WebSphere® MQ connection before the CICSPlex SM environment has been initialized.
  4. It is not possible to install journal definitions (JRNLDEF objects).
  5. Enqueue models forming nested generic enqueue names must be installed either in the disabled state or in order, from the most specific (for example, ABCD) to the least specific (for example, AB*). You can install disabled enqueue models in any order, but you must enable them in order from most specific to least specific. For more information, see Installing BAS global enqueue model definitions.
  6. If the MAS supports the LOGMESSAGE option of the EXEC CREATE command, then you can use the CICSPlex SM system parameter BASLOGMSG(NO) to prevent CICS from logging the BAS CICS resource definitions to the CSDL transient data queue. You can also set BASLOGMSG(YES) to allow this logging to occur to help with problem determination.
