Oracle RAC

Different instances can use different values.

A session is considered to be a blocking session when it is holding resources required by other sessions. For example:

  • The session is holding a lock required by another session.
  • The session is a parallel operation and its consumer group, PDB, or database has either reached its maximum parallel server limit or has queued parallel operations.
  • The session’s PDB or database instance is about to reach its SESSIONS or PROCESSES limit.

This parameter differs from the MAX_IDLE_TIME parameter in that MAX_IDLE_TIME applies to all sessions (blocking and non-blocking), whereas MAX_IDLE_BLOCKING_TIME applies only to blocking sessions. Therefore, in order for MAX_IDLE_BLOCKING_TIME to be effective, its limit must be less than the MAX_IDLE_TIME limit.

Note:

This parameter is available starting with Oracle Database 19c.
