Script Cron issue
Hi All.

I have scheduled the script below in cron (Solaris 8). This script is supported to monitor the output of the websphere was-stat command and send a page out if it finds that one of the JVMs in the JVM_list.txt is down.
Code:
#!/bin/ksh
mailbox=pager_name
cat JVM_list.txt | while read i
do
was-stat | grep $i > /dev/null 2>&1
if [ $? -ne "0" ]; then
mailx -s "The JVM $i is down on server `hostname`" $mailbox
##echo "The JVM $i is down on server `hostname`"
else
echo " The JVM $i is up on the server `hostname`"
fi
done

The Cron entry is as follows
Code:
05 * * * 1-5 /path/to/script/jvmscript/server_name_jvm_monitor.sh > /dev/null 2>&1

The issue is that if I run the script interactively, it works.
but crontab does not seem to be initiating the script as I tried bringning a JVM down and I did not recieve a page.
The script is supposed to run every 5 mins on weekdays.
Can someone look at it and the script and help me debug.

Thanks
Segwar

wbemconfig

wbemconfig(1M)						  System Administration Commands					    wbemconfig(1M)

NAME

       wbemconfig - convert a JavaSpaces datastore to the newer Reliable Log datastore format

SYNOPSIS

       /usr/sadm/lib/wbem/wbemconfig convert

DESCRIPTION

       A Reliable Log directory is created that contains the converted data. This directory is named /var/sadm/wbem/logr.

       The  convert  argument  is the only supported option of this command. You should only run this command after stopping WBEM (CIM Object Man-
       ager) with the init.wbem stop command. Otherwise your data may be corrupted.

       This command successfully converts any proprietary custom MOFs you have created in the datastore, but not any CIM or Solaris MOFs you  have
       modified. These will be destroyed. To recompile any modified CIM or Solaris MOFs into the new datastore, run the mofcomp command on the MOF
       files containing the class definitions.

       Because the wbemconfig convert command invokes the JVM (Java Virtual Machine) to perform conversion of the JavaSpaces datastore,  you  must
       be  running  the  same version of the JVM as when the original JavaSpaces storage was created. After the wbemconfig convert command is com-
       pleted, you can change to any version of the JVM you want.

       To see what version of the JVM you are running, issue the java -version command.

OPTIONS

       The following options are supported:

       convert	       Convert a JavaSpaces datastore to the newer Reliable Log datastore format.
