Autoconfig Basics

am getting lots of request for Autoconfig so I thought lets start with this most powerful tool (in my views) in Oracle Apps .

What is Autoconfig ?
Autoconfig is tool in Apps to configure oracle Applications 11i , Application Tier as well Database Tier.

How to run Autoconfig ?
If you want to configure database tier then you have to execute autoconfig script adautocfg.sh on database tier else if you want to configure on application tier (Middle Tier ) then you have to execute one on middle tier .

Here is the script location
For Database tier its $ORACLE_HOME/appsutil/scripts/$CONTEXT_NAME
For Application Tier its $OAD_TOP/admin/scripts/$CONTEXT_NAME

adautocfg.sh calls adconfig.sh from $AD_TOP/bin which inturn calls adconfig.pl from $AD_TOP/bin

Don't forget to take backup before executing autoconfig.

What source of information for Autoconfig to update configuration files ?
If you are wondering where is configuration information stored about your apps 11i instance based on which it updates your Instance then this file is xml file also called as Context file and its in $APPL_TOP/admin for Application Tier or $ORACLE_HOME/appsutil in Database Tier

I am going to unwrap this xml / context file which is most important file . If you get a chance open this file & go through it so wait for my next post on Context File Contents with explanation & how to put your customization so that Autoconfig can't overwrite them ..
