Re: Cannot connect to Database Oracle Error -1033
Hello,
as Yogeeraj suggested, I am now trying to do a Backup.
As I have no experience, I made a test first on another machine (a B2000 also running HP-UX 10.20) with a similar application.
I used the following command with the following result:
# dd if=/dev/dsk/c2t6d0 of=/dev/rmt/0mn bs=1024k
I/O error
8306+0 records in
8305+1 records out
#
What is the error here?
Is this the correct command to do a backup?
Regards
Pine

Re: Cannot connect to Database Oracle Error -1033
hi,
at the oracle level, there are three ways that you can perform your backup.
1. Export (not recommended)
2. Online Oracle backup using RMAN (need a special setup)
3. Shutdown the database and backup the datafiles using OS utilities.
For option 1.
============
exp system/ file=exp.dmp full=y
For option 3.
=============
if you are not using raw device, you can just copy the datafiles. If you want to know which datafiles you are using, you can issue the command: "alter database using backup controlfile to trace;" at the sql prompt and view the log file generated in the udump directory.
if you need any further help, do let us know
kind regards

Re: Cannot connect to Database Oracle Error -1033
Hello Pine,
please try to create a backup without the problem filesystem.
For /dev/dsk/c2t6d0:
- if you have lvols, try to back them up seperatedly
- try to repeat your dd command. Does it fail at the same block?
- try to copy only the first 8505 blocks with 'dd if=/dev/dsk/c2t6d0 of=/dev/rmt/0mn bs=1024k count=8305'
- try to find information about the size of the bad area with playing with the command
'dd if=/dev/dsk/c2t6d0 of=/dev/rmt/0mn bs=1024k skip=8306 count=10'
- try to copy the disk behind the bad block with 'dd if=/dev/dsk/c2t6d0 of=/dev/rmt/0mn bs=1024k skip=8305'
- if there is a bad spot on your disk, you can mark it as bad for the filesystem with "bad block allocation" but don't ask me how
- you may recreate the lvol and and place a seperate lvol in top of your bad block.
This will work fine if you realy have a bad area on your disk, do not want to buy a new one and the bad area does not grow in size.
- As far as I know - I am not a oracle-expert - you do not need .trc-files to start oracle. If so, you simply could delete that
file and try again. But get some information first, whether or not you realy do not need this file.
I hope, this is of some help for you.
Regards
Ralf

Re: Cannot connect to Database Oracle Error -1033
Hi,
First, Check your alert_SID.log file. You will get hints. You got the error ORA-01033 because you tried to login immediately after issuing shutdown command.
Try it once more.
Regards,
Simon
