The database purge utility for an Oracle event database is implemented as a stored procedure.
sqlplus connect_string @fastpurge.sql
The fastpurge.sql file is stored in the same location as the other scripts generated during database configuration (the default location is profile_root/databases/event/node_name/server_name or cluster_name/dbscripts/oracle).
The connect_string parameter is the Oracle connection string. Use the same database user ID used to create the event database.
