DFS2026 INSUFFICIENT STORAGE AVAILABLE IN MAIN POOL (WKAP) TO PROCESS COMMAND

Explanation

A command was not processed because of insufficient storage in the main pool.

Important: The WKAP cannot be specified at system definition time. System definition sets a value of 5000. You can override the value at execution time by the WKAP= operand on the IMS procedure or the DFSPBxxx member of IMS.PROCLIB.

System action

The command is ignored.

Programmer response

Do one of the following actions:
  • Increase the size of the main pool with the WKAP parameter in the JCL used to start IMS.
  • Reenter the command later, since this problem can be a temporary condition.
  • Reduce storage requirements by reentering the command as multiple commands.
