What are AD Utilities?
AD Utilities are a group of tools designed to install, upgrade, maintain, and patch a specific set of products contained in a given release of Oracle Applications.
What is AutoPatch (or adpatch)?
AutoPatch (adpatch) is a utility that is used to apply individual patches, mini-packs, or maintenance packs to an existing Oracle Applications instance.
What is AD Administration (or adadmin)?
AD Administration (adadmin) performs maintenance tasks on an installed Oracle Applications system to ensure that it runs smoothly. The tasks performed with this utility fall into two categories: database and file system.
What is AD Controller (or adctrl)?
AD Controller (or adctrl) is used in conjunction with other AD Utilities (such as AutoInstall/AutoUpgrade, adadmin or adpatch) to determine the status of workers and restart failed tasks.
What is AD Relink (or adrelink)?
AD Relink (or adrelink) allows you to relink Oracle Applications executable programs with the Oracle Server product libraries. You can run the adrelink utility manually to relink individual executable programs, or use the relink option in the AD Administration utility to relink all executable programs.
How does ADADMIN know which form files to regenerate?
For example if you are looking at the AZ module forms, there will be a file called azfile.drv. This file is located in $PROD_TOP/admin/driver. In your example this is $AZ_TOP/admin/driver.
You can test this by putting a dummy form name under entries for formsdev and forms. This dummy form will be displayed when prompted to select forms for generation via adadmin.
