DFS0431I STORAGE NOT AVAILABLE FOR VSAM BUFFER POOL, RETURN CODE nn
Explanation
An error was encountered while attempting to GETMAIN storage for the DL/I VSAM buffer pool. nn is the return code from the IMODULE GETMAIN macro. For a description of these return codes, see the IMODULE return codes information.
System action
IMS terminates abnormally with abend 0430.
Programmer response
If insufficient storage is available, increase
the main storage available to IMS. If LSO (local storage option)
is selected for the DL/I SAS region, then subpool 251 (low private
storage) for the DL/I region is not large enough for the DL/I buffer
pool. Increase the region parameter in DL/I startup JCL. If LSO=N (no
separate DL/I address space) is selected, then there is not enough
subpool 231 available. Increase the region parameter in the control
region JCL.
