All about Autoconfig in oracle application:

 adautocfg.sh >> Call adconfig.sh which further call adconfig.pl.

adtmplreport.sh>>

[applmgr3@ ~]$ cd $AD_TOP/bin

[applmgr3@1 bin]$ ls adtmplreport.sh

[applmgr3@ bin]$ adtmplreport.sh contextfile=$CONTEXT_FILE target=/u03/applmgr3/inst/apps/PROD_xxx/ora/10.1.3/Apache/Apache/conf/httpd.conf.

adclonectx.pl >>To retrieve the applications tier context file ( if it is lost or deleted accidentally) , execute the following command on the applications tier :

perl <COMMON_TOP>/clone/bin/adclonectx.pl retrieve

adbldxml.sh >>Creates the Applications context file, e.g. .xml

adchkcfg.sh >>script at $AD_TOP/bin. This script will run autoconfig in test mode and create the difference file which tells us what is going to change, when u actually run autoconfig.

This script is used for analysis purpose. It generates a report that shows differences between the original configuration files and the AutoConfig generated configuration files. 

Autoconfig will run in 3 phases.

1.INIT     – Instantiate the drivers and templates

2.SETUP   – Fill the templated with values from xml and create files

3.PROFILE  – Update the profile values in database.

Log/Files Location:

$INST_TOP/appl/admin >> context file location.

$INST_TOP/admin/log  >> autoconfig log file.

Restore a autoconfig :

Partially. Adconfig will create a restore script at $INST_TOP/admin/out/. This restore.sh will copy the backed up files before autoconfig run to its original locations. But the profile values updated in the database can’t be restored back.

Customization:

The way to do customization was to insert custom code between the BeginCustomization and End Customization blocks in the XML file.

It was difficult todocument and keep track of the customizations that were made. Now Oracle hascome up with a better way to manage and maintain customizations.

Create the custom directory in $PROD_TOP/admin/template

$AD_TOP/bin/adtmplreport.sh contextfile=/appl/admin/.xml

target=$FND_TOP/admin/template/appsweb.cfg

The above command would return "$FND_TOP/admin/template/forms_web_1012_cfg.tmp", means

the "appsweb.cfg" file was created from the source Autoconfig template $FND_TOP/admin/template/forms_web_1012_cfg.tmp.

Copy the "forms_web_1012_cfg.tmp" into custom directory created earlier  and then edit it to your requirements

Copy the template $FND_TOP/admin/template/forms_web_1012_cfg.tmp  to  $FND_TOP/admin/template/custom
