ICH560I

Explanation
In MVS™ 5.2.0
and later environments, RACF® data
sets can reside on devices whose UCB is above 16MB.  RACF issued the IOSCAPU macro to "capture" the
UCB into a window below 16MB, and the capture request failed.

System action
The system issues message ICH506I following this
message.
If this message is received during RACF initialization, the system also issues
message ICH502A following this message, which prompts the operator
to enter a new data set name or 'NONE'. The system then waits for
the reply of the operator. Message ICH502A is not issued if this system
is in data sharing mode and is not the first system in the sysplex.
If
this message is received during an RVARY request, message ICH502A
is not issued, and the RVARY command tries the activation again of
the data set five times.

Operator response
Notify your systems programmer.

System programmer response
See the MVS documentation
for the IOSCAPU return and reason codes to determine why the UCB for
the device containing the RACF data
set cannot be "captured" and correct the problem.
If this
message was received during RACF initialization,
the operator is instructed to reply to message ICH502A with the same
data set name after the problem is corrected.
If this message
was received during an RVARY request, the RVARY command is reissued
after the problem is corrected.
