Auto day-end script problem

[ajk_5]

Dear all,

I am working on the auto day-end process which will send email to system administrator if any backup problem. However my script doesn't work, how do I improve the script? Also, the backup_db_test.log has nothing inside, why is that?

Thanks !

The backup problem like tape error, no tape in tape drive, etc. Thanks.

Hi,

1) Nothing in the backup_db_test.loog because you never defined in this script the variable ISD_MENU. Also, quote it with graphes.

$ISD_MENU/backup_db_test.log -->> ${ISD_MENU}/backup_db_test.log

So do for all variables used in the script, it's best.

2) examinate the return code from tar:

tar .....
RC=$?

0 -->> all is OK
>0 -->> some errors, check

3) you could think of using fbackup/frecover, it's faster and with better output. refer to man pages for use and to this forum for a list of config parameters...

These questions may seem silly:

How are you launching this script? It seems familiar. Is it by cron? What's the cron entry?

Has it ever worked?

Did you know that for cron launched scripts you need to build the environment for it, its not like a telnet or secure shell login session?

What if any errors is this script generating.

Hi,
for debugging purpose, as the second line put a
"set -x"
so all commands will be printed.

Also: can you check with "ll" if the file and directory have proper permission for the user starting the commands ?

Maybe the file is empty because it is not writeable by the user.

One thing you might have an issue with is

[ blah blah > 0 ]

This, should be [ blag blah -gt 0 ]
