Can I drop SDE_SESSION_*

[DavidRasmussen]

Loking through my Oracle database I have come across a few hundred tables in the ARCSERVER schema that are named SDE_SESSION_<SDE_ID> Many of which have LAST_ANALYZED dates of 2008 or earlier.  All of them contain zero rows.  Can I manually drop these tables?

SDE_session<SDE_ID>
The SDE_session<sde_ID> table is created when you are using session-based log files.  This table is used to track log file records when a connected session creates a selection set that exceeds the application threshold (100 records in ArcMap).  The SDE_session<sde_ID> table is dropped when the session disconnects.
