Please don't "think" about whether there is I/O
trouble -- test it. There is no sense in eliminating possible clues based
on hoping. To paraphrase Thomas Edison, troubleshooting is 98%
perspiration and 2% inspiration...
Please chase down *all* of the clues
you've been provided:
- Have you attempted to read your control files? Just use the UNIX "dd" or "od" commands to make sure that a read can be performed without an error...
- Have you performed the "cksum" (checksum) command against all of the control files to verify that they are exactly identical?
- Are there any other ".trc" files in the BDUMP directory created around the same time? What does it say?
- Are there any other ".trc" files in the UDUMP directory created around the same time?
- Are there any "core" files in the CDUMP directory created around the same time?
Hopefully, the first thing you did was log a TAR on
MetaLink, right?
