- * Set the default Ingres session locking mode:
- *
- * SET LOCKMODE provides four different parameters to govern
- * the nature of locking in an INGRES session:
- *
- * Level: This refers to the level of granularity desired when
- * the table is accessed. You can specify any of the following
- * locking levels:
- *
- * page Specifies locking at the level of the data page (subject to
- * escalation criteria; see below)
- * table Specifies table-level locking in the database
- * session Specifies the current default for your INGRES session
- * system Specifies that INGRES will start with page-level locking,
- * unless it estimates that more than Maxlocks pages will be
- * referenced, in which case table-level locking will be used.
- *
- * Readlock: This refers to locking in situations where table access
- * is required for reading data only (as opposed to updating
- * data). You can specify any of the following Readlock modes:
- *
- * nolock Specifies no locking when reading data
- * shared Specifies the default mode of locking when reading data
- * exclusive Specifies exclusive locking when reading data (useful in
- * "select-for-update" processing within a multi-statement
- * transaction)
- * system Specifies the general Readlock default for the INGRES system
- *
- * Maxlocks: This refers to an escalation factor, or number of locks on
- * data pages, at which locking escalates from page-level
- * to table-level. The number of locks available to you is
- * dependent upon your system configuration. You can specify the
- * following Maxlocks escalation factors:
- *
- * n A specific (integer) number of page locks to allow before
- * escalating to table-level locking. The default "n" is 10,
- * and "n" must be greater than 0.
- * session Specifies the current Maxlocks default for your INGRES
- * session
- * system Specifies the general Maxlocks default for the INGRES system
- *
- * Note: If you specify page-level locking, and the number of locks granted
- * during a query exceeds the system-wide lock limit, or if the operating
- * system's locking resources are depleted, locking escalates to table-level.
- * This escalation occurs automatically and is independent of the user.
- *
- * Timeout: This refers to a time limit, expressed in seconds, for which
- * a lock request should remain pending. If INGRES cannot grant the lock
- * request within the specified time, then the query that requested the
- * lock aborts. You can specify the following timeout characteristics:
- *
- * n A specific (integer) number of seconds to wait for a lock
- * (setting "n" to 0 requires INGRES to wait indefinitely for
- * the lock)
- * session Specifies the current timeout default for your INGRES
- * session (which is also the INGRES default)
- * system Specifies the general timeout default for the INGRES system
