Storage messages

The following messages are issued for TCP/IP common or private storage shortage problems. The messages are documented in greater detail in z/OS Communications Server: IP Messages Volume 4 (EZZ, SNM).

Specifying a nonzero ECSALIMIT value enables warning messages EZZ4360I, EZZ4361I and EZZ4362I to be issued when a storage shortage occurs. Details regarding the TCP/IP profile GLOBALCONFIG parameter ECSALIMIT can be found in z/OS Communications Server: IP Configuration Reference.

Specifying a nonzero POOLLIMIT enables warning messages EZZ4364I, EZZ4365I, and EZZ4366I to be issued when a storage shortage occurs. Details regarding the TCP/IP profile, GLOBALCONFIG parameter POOLLIMIT, can be found in z/OS Communications Server: IP Configuration Reference. If storage limits were set using the TCP/IP profile GLOBALCONFIG ECSALIMIT statement or the GLOBALCONFIG POOLLIMIT statement look for the TCP/IP warning messages described previously that are issued each time a storage limit boundary is crossed. These messages might indicate a need to raise the limits.

CSM messages always start with the message prefix IVT. For a complete list of messages issued by CSM, see z/OS Communications Server: SNA Messages.

CSM messages identify whether the storage problem is related to CSM ECSA or CSM fixed storage. Examine the IVTPRM00 parmlib member to determine whether the limits for the particular type of CSM storage that is depleted should be increased. Issue the Display CSM command to get more details on current CSM allocation and limits. As previously described, CSM limits can be increased using the Modify CSM command without reloading the initial program.

For more information about the Display CSM and Modify CSM commands, see z/OS Communications Server: SNA Operation.
