variable has no value if run the script automatically/scheduled
Hi All,

I am using ksh as the shell. I have a script that should store variable after executing "onstat" on informix. I can execute it successfully without any issue if run manually, however the value is not showing up when run automatically(scheduled).
Is there anything needed to make the value assigned into PGSIZE?

here is the variable assignment i've done
===============
Code:
PGSIZE=`onstat -b|grep buffer|awk '{print $8}'`
echo "after PAGESIZE "$PGSIZE >> space_out2.log

-------

this is the output when run manually
Code:
=> onstat -b|grep buffer|awk '{print $8}'

4096

all i want to do is to store the output into the PGSIZE variable.

all environment variables needed were setup

Code:
#!/bin/ksh
INFORMIXSERVER
INFORMIXDIR
PATH
ONCONFIG

this is the output if executed via scheduled job.
====
bfore PAGESIZE 4096
after PAGESIZE
=====
<<<<<<<<<<<<<<<<<<<<<<<<< This should have "after PAGESIZE" should have "4096" if executed automatically.

also, just initializing hardcoded
Code:
PGSIZE=4096

, seems to be no problem.

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

	   1.	  Variable assignment lists preceding the command remain in effect when the command completes.

	   2.	  I/O redirections are processed after variable assignments.

	   3.	  Errors cause a script that contains them to abort.

	   4.	  Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a
		  variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file  name  genera-
		  tion are not performed.
