unable to grep the running processes.

Hi All,

We have a shell script(ODS_Load)which loads the data from perticular flat file to oracle table invoking sqlplus based on the parameter.

When we execute the script(ODS_Load) independently, script is working fine and able to load the tables successfully.

We invoke(ODS_Load) with parameter from another script(Wrapper_ODS_Load), which checks if there are any ODS_Load happening for perticular feed if not then it invokes the ODS_load script. If the ODS_Load is happening then it does not again invoke ODS_Load.

Code:

#!/bin/bash
 
CONFLICT=`pgrep -f "ODS_Load $1"`
[ ! "$CONFLICT" ] && ODS_Load $1 &

But the pgrep -f "ODS_Load $1" is not returning any result even though the script ODS_Load is running. Can someone help us debug this issue?

Thanks and Regards
Nagaraja Akkivalli

service

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service	runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current
       working directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script.  service passes COMMAND and OPTIONS to the init script unmodified.  All scripts should support at least the start and stop
       commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start  com-
       mand.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
