Offline dump formatting operations
IMS operators need to be aware that their intervention might be required if a dump is requested at a time when the dump data sets are unavailable or when some other task in the z/OS® system is currently taking an SDUMP.
In these situations, IMS issues
message DFS3906
or DFS3907
. In addition,
CCTL operators must be aware that the CCTL can issue these messages
when the IMS database resource
adapter (DRA) is trying to generate an SDUMP.
