actually i wanted to know what happens at database end.it is getting connction and download the context file and then comparing it.but it was a confusion.

can you please just give some idea what happens at database end in creation of context file

Autoconfig is normally feeded from the context file which is located in the filesystem.
The context files are also stored in the db tier. (inside the database)
So, It is all about s_contextserial.
In cases where s_contextserial in db is higher than the s_contextserial in filesystem , then the values of the context file is derived from what the database.  (from the context file that is stored inside the database)

Thanks for the update erman.i agree

Coming back to original question,how fsclone creates patch context file.

Thanks again for each and every post

Probably using the java : oracle.apps.ad.autoconfig.InstantiateFile.
Using oracle.apps.ad.autoconfig.InstantiateFile+ fsclone_config_txt.tmp  + fsclone_config.txt , your context file gets created, probably.

going inside of oracle.apps.ad.autoconfig.InstantiateFile, is beyond of the scope.
So, your question "how" is answered ..
