Coupling facility structure definition

Your MVS system programmer needs to define the coupling facility structure to use sysplex variables.

If both the BBPARM member BBISSPxx XCFGRP parameter and the AAOPRMxx member SPLXSTR parameter use the defaults, the default structure name is as follows, where BMCAB is the default value for the XCFGROUP and MVAO_ is a hard-coded prefix:

Run the appropriate IBM utility to define the coupling facility structure. For example, this utility might be the IXCMIAPU program that is also known as the Administrative Data Utility.

Run the IBM Administrative Data Utility program named IXCMIAPU to define the coupling facility structure.  For more information about the Administrative Data Utility, see the IBM publication z/OS MVS Setting Up a Sysplex.

An example input statement follows for the utility to create a 2 Megabyte (2,000 KB) structure.

STRUCTURE NAME(MVAO_BMCAB)
SIZE(2000)

If XCFGROUP=YOURCOMP and SPLXSTR=MYCOMP is specified, the effective structure name is BMCAB_MYCOMP. See Specifying-the-name-of-the-coupling-facility for more examples.
