Home -> Community -> Mailing Lists -> Oracle-L -> RE: Are snapshot logs purged?
The more useful course of action, though, would be to find out why the snapshot logs keep growing. Such a situation usually means that the master site thinks other snapshots exist against the log table, and since they're never refreshed, the log entries are never purged.
You might want to consider (in this order) dropping the snapshots, dropping the logs, re-creating the logs, and re-creating the snapshots. Perform some DML on the master tables, then do fast refreshes and ensure that the logs are empty.

See dbms_snapshot.purge_log() in the PL/SQL Supplied Packages Reference.
This procedure purges rows from the snapshot log.

DBMS_SNAPSHOT.PURGE_LOG (
master IN VARCHAR2, num IN BINARY_INTEGER := 1, flag IN VARCHAR2 := 'NOP'); ----------------------------------------------------------------------------
