DL/I I/O errors during backout

IMS handles I/O errors for DL/I databases in the same way for dynamic backout, batch backout, and emergency restart backout.

Errors during dynamic backout
If a database I/O error occurs during backout, IMS issues message, creates an EEQE to record the event, and calls DBRC to flag the appropriate database entry in the RECON data set as needing backout.
Recovering from errors during dynamic backout
Different kinds of failure require different recovery procedures.
Errors during batch backout
The Batch Backout utility tries to handle I/O errors but will terminate processing if a read error occurs.
Errors on log during batch backout
If an I/O error occurs on the input log, you should execute the Log Recovery utility to correct the error.
Errors during emergency restart backout
IMS handles both read errors and failures to open a database during emergency restart in the same way as it does during dynamic backout.
