Installation of CICS resources

This section describes how you can use Business Application Services (BAS) to install resources. Systems must be running CICS®/ESA 4.1 and later, but not all resources are available on all levels of CICS systems; for details, see the individual descriptions of the resource definition objects. The installation facility uses the EXEC CICS CREATE command to create resources independent of the CSD.

As with CICS itself, CICSPlex® SM can install resources either automatically at system initialization time or dynamically into an active system. When you use CICSPlex SM to install CICS resources, those resources may replace any identical resources that may exist in the system.

Notes:
  1. If you are using BAS to automatically install resources 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 the CICS Transaction Server for z/OS® Installation Guide.
  2. There are special considerations when arranging for activation of a DB2® connection via a a DB2CDEF definition. For details, see the CICS Transaction Server for z/OS Installation Guide.
  3. It is not possible to use BAS to install an MQSeries® connection before the CICSPlex SM environment has been initialized.
  4. It is not possible to install journal definitions (JRNLDEF).
  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 enqueue model definitions.
  6. If the MAS supports the LOGMESSAGE option of the EXEC CREATE command, then the CICSPlex SM system parameter BASLOGMSG(NO) may be used to prevent CICS from logging to the CSDL Transient Data Queue, the BAS-CICS resource definitions. BASLOGMSG(YES) may also be set to allow this logging to occur and may be useful for problem determination.
