ORA-01115 IO error reading block from file string

ORA-01115 IO error reading block from file string

Donald,



I don't have your hardware configuration, but I've seen errors like this
on our platform (IBM AIX/IBM Shark San disk).  It happens with us when
we are running an Rman backup to disk and the backup directory is full
(not the same mount point as the file that is reported as being
offline/unavailable).



Just a little oddity that we've experienced.



We ignore the error and make sure we have enough room for backups.



Tom

Subject: ORA-01115 (See ORA-01115.ora-code.com) IO error reading block from file string



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 (See ORA-01115.ora-code.com) 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.

ORA-01115 (See ORA-01115.ora-code.com) IO error reading block from file string (block # string)
Cause: The device on which the file resides is probably off line.
Action: Restore access to the device, then retry the operation.
