DP post-exec script times out

Dave Chamberlin — Wed, 28 Jan 2015 21:13:23 GMT

Greetings. I believe this is a script issue - not data protector issue. I have a post exec script (ksh) I have used for a few years that now has to run remotely rather than locally (on the cell manager). The script runs 5 other scripts. All the scripts start what they are supposed to - but DP waits for 30 minutes and reports failure (due to timeout in the script). The last 3 lines of the main script are below. The two emails are sent but it sits there for 30 minutes - then times out. Any ideas on finding out what the hangup is? Could one of the child scripts cause the issue? How could I find out which one?

echo "$subject" | /usr/bin/mailx -s "PROD BACKUP IS COMPLETE" <emailaddress>
echo "$subject" | /usr/bin/mailx -s "PROD BACKUP IS COMPLETE" <emailaddress>
exit 0

So you know you got to the last mailx? (Any reason you don't use mailx with both addresses?)

Are you starting any background processes (with &)?

I suppose you could use tusc to check and see what ksh is waiting for.

>post exec script

Are you redirecting stdin to /dev/null?

there are only four scripts - the 2nd,3rd, and 4th are run with &. These are running on itanium (hpux 11.31). One strange thing - when I run the same script on a PA-RISC test system (also hpux 11.31) it completes (with a DP test backup).

I di notice that the inet process was still running from the backup, and the log file did not exist. I created the file and one of the child processes was still sending output. We think the script that may still be sending output is:

su - clr -c "/u12/software/jboss/jboss-4.0.1sp1/bin/run_jboss.sh >/dev/null 2>&1"

Is there another way to have this run without returning output to the shell?

thanks

There's nohup(1).

the script that might be hanging does a nohup in it:

nohup java $VM_ARGS -classpath $CP com.clearorbit.rfuiServer.Engine -telnet $PORT -admin $ADMI N_PORT -program $PROGRAM $RFUI_ARGS 1>/home/clr/dtel.log &

In it or to invoke it?

Also, why not redirect stderr too? 2>&1

You may want to redirect stdin too: < /dev/null

Doing the >/dev/null >2>&1 in the postexec script has fixed the problem. thanks
