Usage

The SESSION_LIMIT_TXN_TIME configuration parameter limits how much time a transaction can run in a session, and can prevent individual session transactions from monopolizing the logical log.

The database server terminates a transaction that exceeds the time limit, puts a message in the database server message log, and triggers the event alarm 21019.

The session_limit_txn_time tenant database property set through the tenant create or tenant update SQL API command takes precedent over the SESSION_LIMIT_TXN_TIME configuration parameter setting.
