OSRunPriority Property

Questa funzionalità verrà rimossa in una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.

The OSRunPriority property controls execution thread scheduling for job steps executing operating system tasks.

Settings

Constant	Value	Description
SQLDMORunPri_AboveNormal	1	Slightly elevated priority.
SQLDMORunPri_BelowNormal	-1	Reduced priority.
SQLDMORunPri_Highest	2	Highest priority level allowed by the process priority.
SQLDMORunPri_Idle	-15	No CPU time is spent on this thread unless all other threads are blocked.
SQLDMORunPri_Lowest	-2	Lowest priority level allowed by the process priority.
SQLDMORunPri_Normal	0	Standard priority level.
SQLDMORunPri_TimeCritical	15	No CPU time is given to other processes while the job step executes.
SQLDMORunPri_Unknown	100	The value is not valid.

Osservazioni

Set the OSRunPriority property to alter execution thread scheduling for job steps executing operating system commands. The property specifies a thread priority relative to that granted to an instance of Microsoft SQL Server.

Attenzione:
Setting operating system thread priority can have adverse effects on other processes running on the server. Care should be taken when specifying priorities above normal.
