Steps to recovery or recreate applications context file if it is corrupted or deleted accidentally

Here are the options to recover or recreate applications (db) contextfile

1. download from database
The contextfiles are saved into a database table: FND_OAM_CONTEXT_FILES. In case the contextfile in the file system is corrupted or lost, login to OAM->Site Map->Administration->System Configuration->AutoConfig->View. Will prompt to open or save it.

For EBS Rel 12, you can user adclonectx.pl retrieve to download the contextfile from database. See Appendix 3.

2. use adbldxml.pl to rebuild contextfile see appendix 1.

3. copy a contextfile from other instance and run adclonectx.pl to create a new contextfile. See appendix 2.
