Flushes the article cache. This stored procedure is executed at the Publisher on the publication database.
You should not have to execute this procedure manually. sp_replflush should only be used for troubleshooting replication as directed by an experienced replication support professional.
sp_replflush is used in transactional replication.
Article definitions are stored in the cache for efficiency. sp_replflush is used by other replication stored procedures whenever an article definition is modified or dropped.
Only one client connection can have log reader access to a given database. If a client has log reader access to a database, executing sp_replflush causes the client to release its access. Other clients can then scan the transaction log using sp_replcmds or sp_replshowcmds.
