DFS2862W OPEN/CLOSE ERROR ON EXTERNAL TRACE DATA SET xxxxxxxx.
Explanation
An open or close failed for the listed data set. This message should have been preceded by a system error message.
System action
If disk data sets are used, IMS tries to continue using the remaining disk. If no more disks are available or if tape is used, IMS asks the operator for permission to log IMS trace tables to the OLDS. If the failing data set cannot be closed and deallocated, the failing data set is unusable until IMS is restarted. See DFS2867A for more information about logging IMS trace tables to the OLDS.
