DFS3423E RESOURCE ERROR TYPE=resourcetype SERVICE=servicename FUNC=function RC=returncode NAME=resourcename MODULE=modulename
Explanation
IMS encountered an error initializing a resource control block.
- resourcetype
- The resource type can be one of the following:
- DBBD – database descriptor
- DDIR – database
- LLB – Multiple Systems Coupling (MSC) logical link control block
- LNB – MSC logical link path (msname) control block
- MSCL – MSC logical link control blocks
- MSCP – MSC physical link control blocks
- PDIR – program
- PGMD – program descriptor
- RCNT – Remote logical terminal
- RSCX – resource extension block
- RTCD – routing code descriptor
- RTCE – routing code
- SMB – transaction
- TRND – transaction descriptor
- servicename
- Name of the service that encountered an error. Other than DFSBCB, the services are internal to IMS.
- function
- Name of the service function that encountered an error.
- returncode
- Service return code. If the servicename is DFSBCB, see the DFSBCB return codes.
- resourcename
- Name of the resource that encountered the error.
- modulename
- Name of the module that encountered the error.
System action
In some cases, IMS terminates abnormally with abend 3423. In other cases, IMS continues processing without the use of the resource.
System programmer response
Check whether your MODBLKS data set is generated at the appropriate IMS release level. If you are starting an IMS that references a MODBLKS data set generated at an older IMS release level, the mismatch usually results in the DFS3423E message. If you have converted any MODBLKS data set from a PDS to a PDS/E, make sure all the MODBLKS data sets are defined as a PDS/E (MODBLKSA, MODBLKSB, and the staging MODBLKS).
If the MODBLKS data set is generated at the same IMS release level, copy the SYSLOG and IMS memory dump and contact IBM® Software Support for help. Also save the servicename, function, returncode, and other information from the message.
