INST TOP directory:
(applmgr) - ls
admin/ appl/ certs/ logs/ ora/ out/ pids/ portal/ rgf/
(applmgr) -
The Whys and wherefores:
You may get a question why is the change??
There is a need to separate
Code
Data
Config
to ease maintenance of the system. To avoid NFS/MUTEX related issues. Above issue will get resolved if the configuration/lcck files are stored in local system. Another advantage is to gain performance accessing local file system is better than NFS file system.
This directory $INST_TOP got introduced newly in R12. Instance top contains all the config files, log files, ssl certificates, document root etc. Addition of this directory makes the middle-tier more organised, since data is kept separate from config/log files. Another advantage is that, multiple instances can easily share the same middle tier. To create a new instance that shares an existing middle-tier, just create a new instance_top with proper config files and NFS mount the middle tier in the server.

Hey Suresh,
First of all, i would like to thank you for creating this blog for Apps DBAs. This post as compared to others is really descriptive and i have taken a printout of the same for easily navigating to the log and config directories :)
Nice job. I would appreciate if you take steps to cover some of the R12 issues that you face in day-today life. Myself and couple of my friends have started a blog dedicated to Apps DBAs worldwide.
Check out

Thanks,

Hi Raghu,
Nope, You wont find jserv component related config files. Jserv is 9i techstack component, it got replaced by 10g Oacore OC4J.
Thanks
Suresh
HI Suresh,
You have mentioned that jserv has been replaced by oc4j. So what files do we hv to edit to point oc4j to our custom java classes in $XXHR_TOP? We use this instead of the default $JAVA_TOP.
IN 11i, we modified jserv.properties with wrapper.classpath=/a001/DEV/appl/xxhr/11.5.0/java
Thanks in advance

Hi A,
Thanks for your comment.
Please mention your name going forward to address you.
You have to change the context XML variable and have to run the auto config. if you need exact xml file where the classpath goes into, i think it is orion_application.xml
let me double check and give you. you may review the article http://applicationsdba.blogspot.com/2008/07/r12-cdata-in-context-xml-file.html
mail me at suresh.lakshmanan at gmail.com
Thanks
Suresh
Thanks for your pointer to the CDATA in the new context files. We tested it with modifying the orion-application.xml directly first and ofcourse that wrked. So then we did it the proper way with changing the contect files.

Thanks Aditya. Pleasure helping you out.
Thanks
