SUP_LCCA_ABOVE_16M

Description:

Checks to see whether the residency mode (RMODE), specified for the LCCA control block in the CBLOC parameter of the DIAGxx parmlib member, is the expected value. The default RMODE for the LCCA control block is RMODE 31. The check will look for RMODE 31 for the LCCA control block unless you specify an RMODE of 24 in the RMODE parameter for the check.

Reason for check:

The suggested RMODE for the LCCA control block is RMODE 31.

z/OS® releases the check applies to:

z/OS V1R12 and higher.

Type of check (local or remote):

Local

User override of IBM values:

The following sample shows the defaults for customizable values for this check. Use this sample to make permanent check customizations in an HZSPRMxx parmlib member used at IBM Health Checker for z/OS startup. If you just want a one-time only update to the check defaults, omit the first line (ADDREPLACE POLICY) and use the UPDATE statement on a MODIFY hzsproc command. Note that using non-POLICY UPDATEs in HZSPRMxx can lead to unexpected results and is therefore not recommended. End of change

Parameters accepted:

CBLOC(31), which is the default, specifies that you want the check to generate an exception if it finds that IHALCCA had been specified within the CBLOC VIRTUAL24 parameter of the DIAGxx parmlib member.
CBLOC(24) specifies that you want the check to generate an exception if it finds that IHALCCA either:
- Had been specified within the CBLOC VIRTUAL31 parameter of the DIAGxx parmlib member.
- Had not been specified within the CBLOC VIRTUAL24 parameter of the DIAGxx parmlib member (because CBLOC VIRTUAL31 is the default for the LCCA)..

Reference:

See the CBLOC parameter in the DIAGxx parmlib member in z/OS MVS Initialization and Tuning Reference.
