For our conversion from VSE to z/OS we have a "mass compile" process that runs many compiles at the same time. This has been fine up until when we added "DB2 compiles" in to the mix. Now we are getting things like the following for every second or third compile: 11.02.22 JOB05118 IEC143I 213-30,IFG0194D,EXAM02,COB,DBRMLIB,9220,DB2001,SYS3.DSN910.DBRMLIB.DATA(EXAM02)
"30 An attempt was made to open a partitioned data set (PDS) for OUTPUT,DISP=SHR. The PDS is already open in this condition, and a DCB is already open for output to the data set. The data set might be on the same system or on another system that is sharing the volume. Access was not serialized before the attempt to open the data set." I am guessing that "job 2" is trying to add a member to SYS3.DSN910.DBRMLIB.DATA at the same time that "job 1" is trying to do the same thing (though a different member). Obviously one solution is to single thread the compiles. But I'd rather not if I don't have to. Any other solutions? If I changed to DISP=OLD would this eliminate the issue by making job 2 wait until job 1 is done with the PDS? Why does the link-edit step seem to not have a similar issue? Is it just that the link-edit step completes so quickly that only one job has the PDS open at one time? Or does the link-edit (binder; whatever) have some special stuff that allows it do deal with this situation?
