Release : 14.0
Component :
The "Error 0450 Info 000" errors are occurring because there are too many reports defined to one job.
Here is the definition of the error:
Dynamic Allocation Error 0450: Request would cause the limit of 1635
concurrent allocations to be exceeded.
The RMOSOR02 and RMOSOR04 messages are generated, when using Deliver pre-spool processing due to a problem of exceeding the system TIOT table.
The TIOT table size can be or size 32k or 64K.
32K means that there can be a maximum of 1634 DDnames per STEP.
64K means that there can be a maximum of 3268 DDnames per STEP.
In the job output that exceeded the tape, there can be found information on the TIOT table as follows:
SWA=ABOVE,TIOT SIZE=64K,DSENQSHR=DISALLOW,GDGBIAS=JOB

As a resolution, the client changed the processing of a few reports (with many Distribution IDs defined to them) to different steps in the job.
