Usage

The SESSION_LIMIT_MEMORY configuration parameter limits how much memory a session can allocate, and can prevent individual sessions from monopolizing system resources.

The database server terminates a session that exceeds the memory limit, puts a message in the database server message log, and triggers the event alarm 21016.

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