Title

SYS(x).PARMLIB(IGDSMSxx), SMS parameter settings are not properly specified. (Cat II impact)

Discussion

Configuration properties of DFSMS are specified in various members of the system parmlib concatenation (e.g., SYS1.PARMLIB). Statements within these PDS members provide the execution, operational, and configuration characteristics of the system-managed storage environment. Missing or inappropriate configuration values may result in undesirable operations and degraded security. This exposure could potentially compromise the availability and integrity of some system services and customer data.

Check Content

a) Review the logical parmlib data sets, example: SYS1.PARMLIB(IGDSMSxx), for the following SMS parameter settings: Parameter Key SMS ACDS(ACDS data set name) COMMDS(COMMDS data set name) b) If the required parameters are defined, there is NO FINDING. c) If the required parameters are not defined, this is a FINDING.

Fix Text

The Systems programmer will review the DFSMS-related PDS members and statements specified in the system parmlib concatenation. Ensure these elements are configured as outlined below: Parameter Key SMS ACDS(ACDS data set name) COMMDS(COMMDS data set name)
