We have more 100,000 archived files in archival directory and 4,000 active insta

To clarify, do you mean you'd like to differentiate between recently unarchived processes and active ones? When you run the unarchive script, a log file is generated that lists all the processes that were unarchived

Thanks Aleksi.

Unfortunately, log file does not have any information regarding recently unarchived processes.

Followed Unarchiev approach is: archiveprocess unarchive -file <<file with absolute path>>

Generated log is: Called with parameters: unarchive -file /opt/applocal/dit1/appian/server/archived-process/01/0/process_000dd38f-ad70-8000-0491-680000680000_20141201131233_268516476.l.

Is there away find what are processes un-archieved.

In this case you have both the UUID and the ID. The file name is organized like this:
process_<UUID>_<timestamp>_<PID>.l

So in the example you posted, the PID is 268516476, and you can filter your processes with the pp!id attribute to search for that one.

Additionally you can use Find Archived Processes smart service to get the archived process ids and the date time they archived. forum.appian.com/.../summary
