Re: Error in Exchange

Thanks Todd,

For this useful information. Sure I will contact PSS.
I know about Transaction log files. I read it all ablut in KB.
Will you provide me some linkes to get more info about the role these logs
play in .edb file or with database and how information is saved into .edb
files.

Thanks again

If your Sept 8th backup is good I would restore from that and then do a

using exmerge.

You really should try to find the hardware issue first as it will most
likely corrupt
your database again. I would also open a case with PSS as they can assist
you better
than the newsgroups.

Thanks Todd
If this is then, I have one more question to you,

Database corruption error logged on Sept 14 on our server and I take a
full
backup on Sept 8. Database corruption is gone after daily maintenance is
run.
On Oct 6 I again take a full backup of exchange and as you know, all
transaction logs are saved in that backup. When DB corruption error came,
circular logging is enable on our server, I disable it.

As you mention, I restore the Backup that I take on Oct 6 and replay the
log
files according to the documentation. After that these error’s came in
when
maintenance run.
Tell what is the best option right now. Coz I don’t have transaction logs
in
full backup on Sept 8. do I restore again from last full backup (“what
about
transaction logs after Sept 8)

It's an Exchange database corruption issue most likely caused by faulty
hardware. At this
point your best bet is to restore from backup (before those events began)
and then it
will replay your logs (assuming a full backup has not been able to
complete
since there
errors). If a backup is not available you will need to do a repair on
the
existing database
but you will definitely see some data loss at that point. I would
concentrate on finding
the faulty hardware before that since the problem will most likely come
back.

Hello Friends,
This error messages are logged in Events, when Maintanace is run on
exchange
database.
Information Store First Storage Group: The database page read from the
file
"D:\Exchsrvr\MDBDATA\priv1.edb" at offset 4239945728
(0x00000000fcb87000)
(database page 1035142 (0xFCB86)) for 4096 (0x00001000) bytes failed
verification due to a page checksum mismatch. The expected checksum
was
4445902399428239 (0x000fcb865139568f) and the actual checksum was
4445902533645967 (0x000fcb865939568f). The read operation will fail
with
error -1018 (0xfffffc06). If this condition persists then please
restore
the
database from a previous backup. This problem is likely due to faulty
hardware. Please contact your hardware vendor for further assistance
diagnosing the problem.

Information Store First Storage Group: Online defragmentation of
database
'D:\Exchsrvr\MDBDATA\priv1.edb' terminated prematurely after
encountering
unexpected error -1018. The next time online defragmentation is started
on
this database, it will resume from the point of interruption.

Is this a hardware problem or exchange problem, How can i fix these
errors.

Guri
