FACT(s) (Environment):
AIX 4.3.3
FACT(s) (Environment):
Progress 9.1C
SYMPTOM(s):
Last transaction is missing after applying after-image after crash.
CAUSE:
The last transaction might not have been written out to disk. Whether or not this happens depends on the -Mf value. If -Mf is set to a positive value (the multi-user and batch default is 3), then the last BI file record is only guaranteed to be written out to disk when a user logs out, or when the server or broker process terminates normally. In the event of crash, some transactions may be lost. On multi-user systems, the n argument determines the oldest completed transaction that can be lost.
This behaviour does not compromise database integrity.

FIX:
Redo the transaction.
