VSAM serialization error

Hi All,

I am using ADRDSSU utility to back up a set of online VSAM files. The files are first deallocated, then backed up to tapes using the utility and then allocated back again.

The deallocation and allocation are happening fine.

But, some vsam files in the set are giving me

ADR412E (001)-DTDSC(04), DATA SET <VSAM file name>IN CATALOG <CATALOG name> ON VOLUME <Vol> FAILED SERIALIZATION error. These vsams are not getting backed up. No other jobs are accessing these files at the time of back up.

And even if these files were in use, it should not be a problem as the ADRDSSU utility is used with SHARE option.

Any pointers to solve this problem??

Thanks in advance, for any info regarding SERIALIZATION errors in VSAMs or solutions?

Found the solution (Thanks to volumes of information in the net):

ADR412E (xxx)-mmmmm(yy), DATA SET {dsname | clustername COMPONENT
componentname} [IN CATALOG catname] ON VOLUME volser FAILED
SERIALIZATION

Explanation: An ENQ(EXCLUSIVE), ENQ(SHARE), or dynamic allocation with DISP=OLD or SHR failed after a specified (or defaulted) number of retries. TOL(ENQF) was not specified by the user.

System Action: The data set is not processed. The return code is 8.

Programmer Response: Rerun the job when the data set is not in use by other users. You can increase the WAIT parameters, and if you are not using the COMPRESS command to compress a PDS, you can specify TOL(ENQF).

TOLerate(ENQFailure) specifies that data sets are to be processed even though shared or exclusive access fails.

TOL(ENQF) and FULL or TRACKS are mutually exclusive; you cannot specify these keywords together.

Please do post any comments or suggestions or methods to improve...

Thanks,
