Customizing BBPARM members for an IMS system

SUBSYS

Use this parameter to identify the subsystem name of the BBI PAS that the IMS region should communicate with. The subsystem should be the same as the one specified in the BBIJNT00 member of the UBBPARM data set or an ibbparm data set.

MSGLVL1

Set the message level to MTO, WTO, BOTH, or NONE.

KEYWARN

Use this parameter to set a minimum number of days before expiration warning messages are issued for product keys. The default is 45 days. (The KEYWARN parameter applies to MVIMS Online, MVIMS Offline, and MainView for DBCTL only, and it is used only in the IMS control region, not the BBI-SS PAS.)

AOEINIT

This parameter is used with the DFSAOE00 initialization call. (See BBPARM member IMFSYS00 for more information.)

This is ignored if you define your user exits in an IMS DFSDFxxx PROCLIB member. If you do, you must also define the BMC exit, DFSAOE00, as the last one in EXITDEF list.

AOEEXIT and AOIEXIT

Use these parameters to specify the names of user-written AO exit routines. You can also use AOEEXIT and AOIEXIT to specify the order in which AO exit routines get control and whether a return code is padded. See Enabling AO exit routines for more information. These are ignored if you define your user exits in an IMS DFSDFxxx PROCLIB member. If you do, you must also define the BMC exit, DFSAOE00, as the last one in EXITDEF list.

As distributed, IMFSYS00 activates all MVIMS components in IMS. You can use imsidSYS in the UBBPARM data set or IMFSYS00 in an ibbparm data set to temporarily deactivate one or more components. BBPARM member IMFSYSBB contains information about how to deactivate components. Copy what you need from IMFSYSBB to your UBBPARM imsidSYS member or ibbparm IMFSYS00 member.
