While applying a patch if that patch is failing because of a pre-req then how you will apply that pre-req patch and resume with the current patch?

We need to take the backup of FND_INSTALL_PROCESSES and AD_DEFERRED_JOBS tables and restart directory at APPL_TOP/amdin/SID and then use adctrl to quit all the workers. Then apply the pre-req patch , after that rename u r restart directory to its original name and create FND_INSTALL_PROCESSES and AD_DEFERRED_JOBS tables from the bcakup tables.

Start adpatch session and take the options want to continue previous session.
