IGWRH0151E
The check detects SHCDS that is not big enough on your system. SHCDS needs to be at least MinSize MB.

Explanation

If SHCDS is too small, the system might potentially experience problems. The initial size of the SHCDS needs to be at least the size indicated in the message text. A larger size should be used if a large number of recoverable data sets will be opened between a large number of recoverable subsystems. The recommended minimum size displayed by this health check is rounded up to the nearest MB.

In the message text:
MinSize
SHCDS minimum size.

System action

The system continues processing.

System programmer response

Increase the SHCDS size to a value greater than the minimum value specified in the message text.

Problem determination
