The scripts mentioned here are the default start scripts for IBMs Websphere product. They themselves run a whole lot of commands and any of these commands can fail for some or the other reason.

In other words: nothing of the information you gave us so far is sufficient to find out the reason. our script calls four other scripts and this process probably never fails and never will fail. That does not mean, though, that all the scripts started this way will finish sucessfully - each of them could fail for some or other reason. I have worked with a server running Websphere once and i know that it can be tricky sometimes to find ot why it failed to start.

I fear it will boil down to thorough troubleshooting on your side to find out the reason. The following are just some (very general) suggestions which may or ma not help you find the problem.

- You run your script under bash instead of ksh. bash is not the systems default shell and hence using it a potential risk. While i suppose it won't make any difference it is on the safer side to use "/bin/ksh" instead of bash.

- Try inserting "set -x" at the start of the four mentioned scripts and capture the output to some file to see what is going on:

Code:

#!/bin/ksh
/opt/IBM/WebSphere/AppServer/profiles/Dmgr01/bin/startManager.sh  >/tmp/start.1.log 2>&1
/opt/IBM/WebSphere/AppServer/profiles/AppSrv01/bin/startNode.sh  >/tmp/start.2.log 2>&1
/opt/IBM/WebSphere/AppServer/profiles/AppSrv01/bin/startServer.sh server1 >/tmp/start.3.log 2>&1
/opt/IBM/HTTPServer/bin/apachectl start >/tmp/start.4.log 2>&1

If something fails you can analyze the files /tmp/start[1-4].log then. This will not fix any problem itself, just help you analyze the situation when it happens.

I hope this helps.

sory i could't undestand "interesting" , problem not a joke?

This script auto starts the application server and apache on system stratup It works fine but some times it fails and the script does't start the application server or appache . means that script fails. have u nay idea , if then write .
thanks

i have automated it using the procedure below

for example my scrip name is "autoscript.sh"

#!/bin/ksh
/opt/IBM/WebSphere/AppServer/profiles/Dmgr01/bin/startManager.sh >/tmp/start.1.log 2>&1
/opt/IBM/WebSphere/AppServer/profiles/AppSrv01/bin/startNode.sh >/tmp/start.2.log 2>&1
/opt/IBM/WebSphere/AppServer/profiles/AppSrv01/bin/startServer.sh server1 >/tmp/start.3.log 2>&1
/opt/IBM/HTTPServer/bin/apachectl start >/tmp/start.4.log 2>&1


After writing this script . i have copied it into /etc/init.d/ directory and then i have created a link in /etc/rc3.d/ directory using command " ln -s /etc/init.d/autoscript.sh S99script

So this works fine but i don't know some times it stops working . May be there is some problem with application server or may be due to automation .
if u have any idea then write here.
Thanks

Have you looked at the log files? What do they read like when the process fails?

Have yo inserted "set -x" or "set -xv" into the scripts mentioned in your script?
