How can we change the location of conc manager logfiles $APPLCSF/$APPLLOG?

1)Make sure service should not be runing.

[applmgr@apps scripts]$ ps -fu applmgr
UID        PID  PPID  C STIME TTY          TIME CMD
applmgr  26816 26815  0 14:51 pts/1    00:00:01 -bash
applmgr  27723 26816  0 15:35 pts/1    00:00:00 ps -fu applmgr
[applmgr@apps scripts]$


2)Take the backup of old xml file before you make changes to it.
cp -r PROD_apps.xml PROD_apps.xml_08mar2013


3) $APPLCSF existing location

[applmgr@apps admin]$ echo $APPLCSF/$APPLLOG
/u02/inst/apps/PROD_apps/logs/appl/conc/log
     
                         (OR)              

Also you can check with the below commands.

To extract one parameter from xml use grep
=========================================

[applmgr@apps log]$ grep -i s_applcsf $CONTEXT_FILE
         <APPLCSF oa_var="s_applcsf">/u02/inst/apps/PROD_apps/logs/appl/conc</APPLCSF>

To grep multiple parameter use egrep
=================================================
[applmgr@apps log]$ egrep -i 's_applcsf|s_appllog|s_applout' $CONTEXT_FILE
         <APPLCSF oa_var="s_applcsf">/u02/inst/apps/PROD_apps/logs/appl/conc</APPLCSF>
         <APPLLOG oa_var="s_appllog">log</APPLLOG>
         <APPLOUT oa_var="s_applout">out</APPLOUT>
[applmgr@apps log]$

4)change the location and run autoconfig

i have changed the value of $APPLCSF  in xml file to /u02/inst,$APPLLOG to log and $APPLOUT to out only .once parameters are changed in the xml file 
run autoconfig in order to reflect it.

When you grep it .It will show you modified value.
[applmgr@apps admin]$ egrep -i 's_applcsf|s_appllog|s_applout' $CONTEXT_FILE
         <APPLCSF oa_var="s_applcsf">/u02/inst</APPLCSF>
         <APPLLOG oa_var="s_appllog">log</APPLLOG>
         <APPLOUT oa_var="s_applout">out</APPLOUT>
[applmgr@apps admin]$


Still it will show you the old value as you have not run the autoconfig,just run autconfig to reflect it.

[applmgr@apps admin]$ echo $APPLCSF/$APPLLOG
/u02/inst/apps/PROD_apps/logs/appl/conc/log


Now go to script location and run autoconfig.

once autoconfig completed successfully source the env file.

[applmgr@apps appl]$


Concurrent manager logfile location successfully  changed to /u02/inst/log .

Re cap
=====
1) Services should not be running
2)Take backup of old xml file
3)change location in xml file.
4)Run autoconfig.sh
5)source env and check location
