We have started experiencing this error in the last few weeks and are
trying to identify the cause. We opened a ticket with Oracle and one with
HP (SAN).I just checked the logs from the web servers and found this
ORA-01115 error was logged by the web application 6 times yesterday between
2:49 and 3:10 PM. We're not sure if it's both nodes or just one. The last
time it had been logged previously was 12/22/05. Four of those times, it
was the same file that our batch process had a problem with --
PARTIES_DATA01.dbf. On the other 2 occasions, it was PARTIES_DATA02.dbf and
LOCATION_DATA01.dbf.
HP says the SAN is healthy, Windows hasn't logged any issues, and Oracle
says it isn't their problem. If anyone has a suggestion for diagnosing
this, I'm all ears.
