R12.2 scripts for System Configuration

adautocfg.sh - This script is used for running AutoConfig.
adchkcfg.sh - This script may be run before running AutoConfig to review the changes on running AutoConfig.
admkappsutil.pl - This script is used while applying patches to the database tier. Running this script generates appsutil.zip, which may be copied over to the database tier to migrate the patch to the database tier.
adRegisterWLSListeners.pl - This script is used to listen to changes to the WebLogic Server configuration parameters and update the context variables accordingly.
adSyncContext.pl - This script is used to explicitly pull the values of the WebLogic Server configuration parameters and synchronize the context variable values like synchronization of the OHS parameters.
GenCtxInfRep.pl - This script can be used to find out detailed information about context variables and the templates in which they are used, given all or part of a context variable name as a keyword.
adtmplreport.sh - This script can be used to gather information regarding the location of the AutoConfig templates, provided the location of the instantiated files and vice versa.
Run adRegisterWLSListeners Tool on the Application Tier
The adRegisterWLSListeners tool has been introduced to perform synchronization of context variables with the associated Oracle WebLogic Server configuration parameters.
This tool does not listen for changes to the Oracle HTTP Server configuration parameters.
Once started, adRegisterWLSListeners keeps running, listening for changes to the WebLogic Server configuration and synchronizing the context files stored in the database.
This tools starts/stops along with the WebLogic Admin Server.
Run SyncContext on the Application Tier
The adSyncContext.pl script reads the WLS configuration parameter values and synchronizes them with the context variables.
This is used to synchronize the OHS configuration parameters with the respective context variables.
This mechanism is called the 'feedback loop‘
The SyncContext tool is one of the tools used for explicit synchronization of the context variables with the WLS configuration parameters.
In Oracle E-Business Suite Release 12.2 some important configuration files like httpd.conf and ssl.conf  are no longer maintained by AutoConfig.
 Oracle Enterprise Manager 11g Fusion Middleware Control should be used to maintain these configuration files as well as making additional changes to Context File variables.
