Issue with wm.tn.archive.archive

Hello All,

We are trying to purge the data in TN DB.
we tried to use the TN-BIS wm.tn.archive.archive to purge the data and when we run this service its running for ever without any results.
The criteria we are giving for that service is 30 / 90
As of now we have 5months of data in TN DB.
Could some one give me some suggestions to resolve this issue please?

i am using wM 6.1

Thanks
