Check CSVTAM_CSM_STG_LIMIT determined that the value specified for the maximum CSM storage for the FIXED or ECSA storage types (or both) as defined in the CSM Parmlib member IVTPRM00 is less than the minimum value specified for the check.
Message ISTH002I is displayed prior to this message for each CSM storage type that failed the check.
The system continues processing. However, eventual action might need to be taken to prevent a critical depletion of CSM storage resources.
Contact the system programmer.
The default values in IVTPRM00 are 100M for both FIXED and ECSA. However, IBM® suggests that they initially be coded at 120M MAX ECSA and 120M MAX FIXED. Monitor the system for one week with DISPLAY CSM command to determine peak usage. Adjust IVTPRM00 MAX ECSA and MAX FIXED values to 1.5 times the highest value indicated in the DISPLAY CSM outputs. You must adjust your IEASYSxx CSA ECSA subparameter to include the additional amounts of ECSA that CSM will be using. It is recommended that the CSA ECSA subparameter in IEASYSxx be at least 20% more than the ECSA value specified for CSM use in IVTPRM00.
