Description
This bug is only relevant when using Oracle Disk Manager
This fixes 2 problems with diagnostic messages (it does not fix the root cause of any existing block corruption).
The first problem is this msg in the alert log which shouldn't happen:
ORA-17500: ODM err ... Mirror number too large for given offset
The second problem is tracefiles msgs not showing the correct mirror
name where a good version of the block was read, eg the message shows:
Read datafile mirror 'Not able to find mirror name' ...found valid data
Read datafile mirror '' found valid data
Rediscovery NotesThe alert log has this error messsage which shouldn't happen:
----
Errors in file <tracefile_filespec>
ORA-17500: ODM err:ODM ERROR V-41-3-2-207-5 Mirror number too
large for given offset
----
And/or the tracefile has these kind of messages:
- on ODM storage:
Read datafile mirror 'Not able to find mirror name' (file <f>,
block <b>) found valid data
- on ASM storage:
Read datafile mirror '' (file <f>, block <b>) found valid data
WorkaroundNone.
