Unlike the Audit Log, StarTeam does not have a server console option to delete/purge the security log. So purging the contents of the Security Log can only be done at the database level. There are two options are available:
1. Open SQL or Oracle enterprise manager console and run the command
execute purge_seclog XX
The XX denotes the number of days to purge data from the table.
2. Open SQL or Oracle enterprise manager console and run the command
TRUNCATE TABLE " syn_ObjectSecLog”
This operation is almost instant and much faster than option 1 above.
Please take a database backup before attempting any of the operations above.
