Is there way to Delete entries in TN database.
Or purge the TN databse and have data only for 1 year or so?
If we can do it, Please tell us how do we do it.
You can use TN built in service (wm.tn.archive.archive)which gives flexible for deleting the data from BizDoc table or else it can purge the log data by providing certain time span.
HTH.
