unable to execute a script from cron, but possible from CLI

[jerish sunny]

I am using the attached shell script. when i execute it from CLI it is working fine. But when i set it as cron it is not executing correctly and giving result as 'thread value not found for process. process might be stopped'

hi,

could you provide the line from crontab ???

most of this error is there is no full path to the script or shell defined .....

You should always use full pathes to binaries!

Not

"application"

but

/usr/sbin/application

for example.

[jerish sunny]

0,5,10,15,20,25,30,35,40,45,50,55 * * * * /var/opt/TnDM/threadscript/ThreadCount.sh > /var/opt/TnDM/threadscript/debug.txt 2>&1

This is the crontab link

[jerish sunny]

my understanding is that it is not able to write the value into the file $LOG_FILE.
in this line /opt/perf/bin/glance -j 1 -f $LOG_FILE -iterations 1 adviser_only > /dev/null

hi,

i tink you should define shell before the

/bin/sh ( for example ) /var/opt/TnDM/threadscript/ThreadCount.sh

[jerish sunny]

i tried adding /usr/bin/sh but no difference in output

I'm sure you will find something like "not found" in your debug.txt, because you use awk etc. without path.

Hi Sunny,

There is a problem in glance command, I also faced the same problem long back. Whenever you execute the script manually, you can be. but while executing through cron, you can't. I am sure this is because of glance command only...


Other problem may be because of profile file, you execute .profile file with the absolute path in the top of the script as while login into the server, the profile will get executed which used to set all environment variable for you. but while its in cronjob, you need to execute it manually...

like: "./~home/.profile"

What does your debug file tell you?
