DFS3905W IMS DUMP REQUEST ERROR - t SDUMP PROCESSING ERROR, RC=r-ccc

Explanation

The IMS dump assist module (DFSFDMP0) received a nonzero return code from SDUMP while processing an IMS SDUMP request. The meanings of the variables are:
t
P or S, indicating whether the request was a primary or secondary SDUMP request
r
SDUMP return code
  • 04=partial memory dump created
  • 08=no dump created
ccc
The reason code taken from SDUMP (the value is UNK, if no reason code was available). For a partial memory dump (return code=04), the value of ccc is N/A. In this case, obtain the reason code from z/OS® message IEA911E or IEA611E.

System action

If this is the primary SDUMP request (t=P), IMS retries with a secondary SDUMP for the following conditions:
  • A partial memory dump was created (return code 4) which was not due to a QUIESCE=YES request that could not be honored.
  • No memory dump was created (return code 8), but the reason code is one of the following: 001, 255, 005 through 009. A retry is not attempted if the internal parameter list passed by the caller of the dump assist routine specifies no secondary memory dump.

If the secondary SDUMP fails, this message is issued with (t=S) when the SDUMP return code is 4; or when the reason code does not indicate that the SVC memory dump was suppressed either because of another SVC dump in progress or because a SYS1.DUMP data set was unavailable.

When both SDUMP requests fail, IMS online memory dump formatting is permitted if the FMTO parameter you specified allows it.

Operator response

See the SDUMP message issued before this message to determine if any action must be taken. Make sure that the dump produced is processed according to your installation procedures.
