The mechanisms of recovery in IMS

IMS is designed to be recoverable and has a number of mechanisms to help you in these areas. Some function automatically; others require your involvement.

Successful recovery depends on two things:

• Having a safe point to return to, a known point of integrity. This is a point at which you know data is correct and make a record of it.
• Keeping track of what processing has been done since that safe point.

If these two types of information are gathered, recovery is almost always possible.
