DFS2134 INVALID SYSID DETECTED LINK x


or

INVALID SYSID DETECTED I: sss1/name1,
D: sss2/name2

Explanation

The first form of this message results when the receiving IMS detects that sss2 is invalid. sss2 is not defined in the system generating the error.

In the message text:
sss1/name1
The source SYSID and source LTERM name for the input system.
sss2/name2
The destination SYSID and destination LTERM or TRAN code of the processing system.
The second form of this message results when the sending IMS detected that the source SYSID, the destination SYSID, or both SYSIDs are invalid. This situation occurs during communication between a Version 6 IMS system and a pre-Version 6 IMS system, which does not recognize a SYSID higher than 255. Possible errors are:
  • A message with a source SYSID lower than 256 has a destination SYSID higher than 255.
  • A message with a source SYSID higher than 255 has a destination SYSID lower than 256.
  • A message has both a source and destination SYSID higher than 255.

The source and destination SYSID are located in the MSNBOSID and MSNBDSID fields of the MSNB. The link number is x.

When any of the errors occurs, the Message Control/Error exit routine receives control. If the exit routine requests the default action, the DFS2134 message associated with the error is issued.

This message can also be issued when the Message Control/Error exit routine is customized in the sending or receiving system to specify an incorrect exit flag, or the exit flag is correct, but an error was encountered while IMS was performing the requested action and the associated default action was performed.

System action

IMS logs the message in error, using log record type X'64', and removes the message from the system.

System programmer response

To find and correct the error, take the following actions, as appropriate.
  • Correct the SYSID errors in the TRANSACT, LTERM, or MSNAME definitions in the system definition.
  • Determine the default action from the Message Control/Error exit routine, DFSCMUX0.
  • Correct the exit flag or the destination for reroute in the Message Control/Error exit routine, if appropriate.
