DFS3906A REPLY "S" TO SKIP, OR "U" TO RETRY AFTER CLEARING A DUMP DATA SET

Explanation
 An IMS SDUMP request failed because
all system memory dump data sets are currently full.

System action
 The operating system did not create an SDUMP.
IMS waits
for the operator to respond.

Operator response
 You can retry the request, skip taking a
memory dump, or reissue the equivalent of a primary memory dump.
To retry the SDUMP request, clear one or more memory dump
data sets and reply U.
To skip creating
a memory dump, reply S, but be aware that IMS does
not try to create any more SDUMPs for this IMS error.
To
reissue the equivalent of the primary SDUMP request, enter an operator DUMP command
for the IMS CTL, DL/I, DBRC, and IRLM address spaces;
then reply S to the message you receive.
If
the FMTO parameter specified allows online formatting, and if you
replied S, online formatting can be initiated.
