We had a situation where someone was executing SARBCH with the input parameter of
/LIST ID=JOB*
GEN=*
In the execution JCL, they omitted the REPORT DD statement. Subsequently, a message was issued, to the JES WTO pool, for every report that was being processed by the /LIST command. The message written to the JES WTO POOL was:
IEC130I REPORT DD STATEMENT MISSINGWe would like to request that SARBCH be modified to FAIL, when the expected DD statement is missing, rather than issue the message over and over. In situations where there are large numbers of reports, the WTO buffer pool can fill very quickly as the message are issued very very quickly. In our example the message was issued 518 times in less than a second.
This resulted in several processes being impacted and failing with S02B abends during this time period.
