After a failure, a VTAM® application
program that has enabled persistent LU-LU session support is in one
of three recovery states:
- Recovery Pending
- The application program fails, and the recovering application
program has not opened its ACB.
- Recovery-in-Progress
- The recovering application program has opened its ACB, and sessions
are pending recovery. The application program remains in this state
until the last session is either restored or terminated.
- Recovery Complete
- The application program has restored all modes.
Note: VTAM retains
a mode even if it has no associated sessions at the time of the failure.
The mode must be restored before it can be used.
