When formatting the couple data set to support CFRM policy data, the value specified for MAXSYSTEM should match the value specified for MAXSYSTEM when formatting the sysplex couple data sets. For a CFRM couple data set — DATA TYPE(CFRM), valid data names are POLICY, CF, STR, CONNECT, SMREBLD, SMDUPLEX, and MSGBASED.

ITEM NAME(POLICY) NUMBER( )

Specifies the number of administrative policies that can be defined within the data set. (Default=6, Minimum=1, Maximum=32)

ITEM NAME(CF) NUMBER( )

Specifies the number of coupling facilities that can be defined within a policy. (Default=8, Minimum=1, Maximum=16)

ITEM NAME(STR) NUMBER( )

Specifies the number of coupling facility structures that can be defined in one policy. Note that this number refers to structure definitions, not to the number of allocated structure instances (one structure definition can refer to more than one allocated structure instance, as would be the case for a structure that was being rebuilt or duplexed). (Default=50, Minimum=1, Maximum=2048)

ITEM NAME(CONNECT) NUMBER( )

Specifies the number of connections that can be defined for a coupling facility structure. (Default=32, Minimum=1, Maximum=255)

ITEM NAME(SMREBLD) NUMBER(1)

Specifies that this CFRM couple data set supports the system-managed rebuild process.

ITEM NAME(SMDUPLEX) NUMBER(1)

Specifies that this CFRM couple data set supports the system-managed duplexing rebuild process. Use this statement only when formatting a CFRM couple data set for systems at z/OS® Release 2 or higher. Specifying SMDUPLEX implies support for SMREBLD, regardless of whether SMREBLD was explicitly specified.

ITEM NAME(MSGBASED) NUMBER(1)

Specifies that this CFRM couple data set supports message-based event and confirmation processing. Use this statement only when formatting a CFRM couple data sets at systems at z/OS Release 8 and higher. Specifying MSGBASED implies support for SMREBLD and SMDUPLEX, regardless of whether they were explicitly specified.
