DFS2202I PERMANENT I/O ERROR ON IMSMON.

Explanation
 The logger attempted to write to the monitor log
(ddname IMSMON). However, either a permanent I/O error occurred, or
all space allocated to the monitor data set was used.

System action
 IMS monitor logging is stopped.

Programmer response
 The IMS monitor
must be restarted under either condition. You might have to restart IMS.
If
a permanent I/O error occurred, scratch and reallocate the IMSMON
data set. If the monitor data set was allocated using the IMSMON DD
statement in the IMS startup job, restart IMS. IMS does
not need to be restarted if the data set is dynamically allocated.
If the data set ran out of space, DFSUTR20 can be used
to report the current contents, and the monitor can be restarted. IMS does
not need to be restarted, regardless of the allocation method of the
data set.
