CSVTAM_T1BUF_T2BUF_NOEE

Description:

Checks the T1BUF and T2BUF buffer pool allocations for the system when Enterprise Extender (EE) is not being used.

Reason for check:

The T1BUF and T2BUF buffer pool is used exclusively for Enterprise Extender (EE) functions that use QDIO or HyperSockets. If EE is not being used, the T1BUF or T2BUF buffer pool allocations are not optimal if set above their default values (16 for T1BUF and 8 for T2BUF).

z/OS® releases the check applies to:

z/OS V1R9 and later.

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
