Introduction to IMS operations and recovery

For any large system, operations and recovery go together: operations refers to the day-to-day activities involved in keeping the system running smoothly, and recovery refers to the activities required to bring a failed system back online.

Information about operations would be incomplete if it did not describe what you need to do for recovery, when the system (or some part of it) runs into problems.

Another important task related to operations is planning for both day-to-day operations and for recovery. Part of the task of planning is developing procedures that specify the roles of the IMS™ operators and system programmers. These procedures clarify the responsibilities of each of these roles.

This topic introduces both operations and recovery for IMS and describes some of the tools provided by IMS and z/OS® for both tasks.
