ORA-01110, 01115, 27072 during database startup

[BLADE_1]

hi,

Oracle ver. 8.0.5
OS - HP UX 11.0

I did a database cloning from my development server to another server..Both the platforms are identical.

The cloning was successful. Then suddenly after 3-4 hrs the database shutdown abnormally..I checked the alertlog and found the above ORA- errors. All these errors were pointing to datafiles in filesystems mounted on the same volume group VG03.

Last week we had the same problem so we thought that the disk is the problem and replaced the disk and did the cloning process.

We don't have LTO on destination server thats why we did NFS and copied the offline files using CPIO.

I thought it might be because of largefiles disabled but then the files which we were corrupt were of varying sizes 150 mb to 2 GB. And there are other files which are of 2 GB on the same filesystem which don't have this problem.

Anybody has any clues?

Error tells that you have some problem with the disk on that VG.

I/O problems.


check the /var/adm/syslog/syslog.log for further messages on the same.
REvert with those messages

Thanks

Hi

It seems to be Bug 774252 which is fixed in 8.0.6.0 and 8.1.5:

<774252>
: ORA-27072 scanning across a 2Gb offset in a file
To determine if this is the problem that you are hitting we need to look at the
block number being reported with the ORA-01115 error. If this is multiplied by
the DB_BLOCK_SIZE and we are on the 2GB boundary.

hi,
Done that...no error messages..This disk resides in a Hash box..we faced the same problem last week so we replaced it with a new disk..Funny thing is only some files are getting corrupted..
The filesystems on these vg are mounted and i can access them and even create some files in it..


We are trying to figure out if it could be the disk cage that is causing a problem..

hi christian,

ORA-01110: data file 59: '/oracle/D02/sapdata8/protd_2/protd.data2'
ORA-01114: IO error writing block to file 59 (block # 1)
ORA-27072: skgfdisp: I/O error

Filesize is not the problem..

If the bug was the problem then it should corrupt my other 2GB files residing on same filesystem as well as other filesystems..

What are the permissions of the datafiles that you are trying to move.

YOu should have permissions 660 on the datafiles.

check the attachment

hi,

The permissions and ownership are okay..no problem with that..rw-rw---- for all files..

After these messages you should have got a HPUX error number.What is that?

Please post your logfile


Thanks

The problem could be with

1.permissions of the datafile(which is okay with your env)

2.Free space on the file system
Can the file system accomodate that file into that(sufficient amount of free space)

Hello BLADE

My error: Bug 774252 is only reported for SOlaris

nevertheless:

Note:49946.1
Note:62427.1
Note:62407.1
BUG: 749600

said that certain 'core' functions in Oracle and it's tools do not support large files (>2GB) and shows your errors (especially in 8.0.5 but even in 8.1.5).
So this errors may not arise continuously and on all datafiles greater than 2 GB.

Hint:
- not to use files larger than 2 GB
- Upgrade to 9.x

Note this:
11.0 8.0.5 64-bit Desupported
11.0 8.0.5 Desupported
