DFS3902W IMS DUMP REQUEST ERROR -INVALID CALLER TYPE, xx

Explanation

The caller type passed to the IMS memory dump assist module (DFSFDMP0) in the DFSDPARM control block for an IMS memory dump request was invalid. The hexadecimal field xx identifies the caller type. One of the following conditions caused this error:
  • The level of DFSOFMD0 was not the same as the level of the DFSDUMP macro and the DFSDPARM control block.
  • The DFSDPARM control block was overlaid.
  • The IMS memory dump requester did not use the DFSDUMP macro to insert the caller ID field in the DFSDPARM control block.

System action

DFSFDMP0 creates a memory dump of the caller's address space and the control region address space only.

Operator response

You do not need to act immediately, but tell the IMS system programmer that you received this message.
