oracle backup is hanging up on one datafile
When we are making a backup of SAP/oracle database it hangs up in only one data file ├в /oracle/
1. How to resolve this?
2. Is this file corrupted taking into his account that the database is running with no problem.
Thanks with best regards,
A

Re: oracle backup is hanging up on one datafile
I tried two different methods of backup:
One is using sapdba brbackup utility which is utilizing dd and cpio commands and the other is using offline fbackup.
Both of them failed on this file.

Re: oracle backup is hanging up on one datafile
any error messages in syslog.log? Try a cat failingfile > /dev/null to see, if you have disk problems.

Re: oracle backup is hanging up on one datafile
In the syslog.log there are no indication for certain problems in regards of this file. However, i tried the command cat failingfile> /dev/null and it reports
cat: Cannot open failingfile: No such file or directory

Re: oracle backup is hanging up on one datafile
All files that i tried cat on was OK except this file it hangs up with no result and it is not possible even to kill the process using unsafe kill.

Re: oracle backup is hanging up on one datafile
is this file on another lvol than the others?
Can you umount all lvols and then mount them again? Maybe you will have to reboot the machine. The hanging cat process seems to point to some more serious disk error.
