return value of frecover

AYMA — Thu, 09 Mar 2006 04:34:44 GMT

Hi,
what are the return values of frecover ?
The man of fbackup gives the return values but nothing in the frecover man.....
I have tried different scenarios and I have obtained only 0 (success) or 1 (problem) for frecover.
Are other return values existing ?

Best regards

hi,

0 upon normal completion,

1 if it is interrupted but allowed to save its state for possible restart

2 if any error conditions prevent the session from completing.

hope this helps!

kind regards

Thanks for your response,
I'am not sure for the return value 2.
I have tried this scenario.
During the frecover command (frecover -r -f /path/backup_file -v), I erase the backup file ( > /path/backup_file) for simulating a DLT or disk problem. The frecover exits with this message :
frecover(2104): zero length read from disk file. Frecover exiting

But the exit code is 1 and not 2.
Why not 2 ?

Ayma,
the full list of errors seems to be accessable via:
dumpmsg /usr/lib/nls/C/fbackup.cat | more

Ayma,
sorry, previous message was fbackup error.
Frecover at:
dumpmsg /usr/lib/nls/C/frecover.cat | more

Hi,
Thanks for your response.
No problem for fbackup.cat instead of frecover.cat.
In fact, this command (i don't know it) gives the error code but I just want to know the RETURN VALUES or exit code obtained with echo $? (like in the frecover man with 4 values)
yogeeraj says :
"0 upon normal completion,
1 if it is interrupted but allowed to save its state for possible restart
2 if any error conditions prevent the session from completing."

But I never have the 2 value during my check, only 0 for success and 1 for problem.

Ayma,
man frecover does not list any return codes. So I would say there is no list.

fbackup and frecover have been around from the days of 1Gb file system limits and have 'organically grown' i.e. without full documentation.

As you said, you have only found 0(success) or 1(problem), as have I.

So those are the return values you can code for.
If you want to be more specific with error identification, my previous answer should give you enough error codes to go with.

Thanks Peter.

I agree with you and I close the thread.
