| The wait type PREEMPTIVE_OS_GETPROCADDRESS is ranked #14 by Stedman Solutions and Database Health Monitor. Wait statistics, in the context of SQL Server, refer to the amount of time that a query spends waiting to access data in the database. When a client application requests data from the database, the request is placed in a queue and the client application must wait for its turn to access the data. The time that the query spends waiting is called a "wait" and is tracked by SQL Server. This information can be used to identify potential performance bottlenecks and optimize the performance of the database. Wait statistics are commonly used by database administrators to diagnose and troubleshoot performance issues in SQL Server. In order to efficiently manage and retrieve data from a SQL Server database, the system uses a process called "waiting." When a client application requests data from the database, the request is placed in a queue and the client application must wait for its turn to access the data. One common wait type in SQL Server is the PREEMPTIVE_OS_GETPROCADDRESS wait type. This wait type occurs when a query is waiting for the operating system to return the address of a specific function or routine. This is typically done when the query needs to call an external function or routine, such as a function in a dynamically-linked library (DLL) or a system-level function. When a query encounters a PREEMPTIVE_OS_GETPROCADDRESS wait, it means that the query is waiting for the operating system to return the address of the requested function or routine. This wait type can occur when multiple queries are trying to call the same external function or routine simultaneously, or when the function or routine is slow to respond. To minimize the occurrence of PREEMPTIVE_OS_GETPROCADDRESS waits, it is important to ensure that external functions and routines are called efficiently. This can be achieved by properly managing the use of external functions and routines, and by optimizing the performance of the external code itself. In summary, the PREEMPTIVE_OS_GETPROCADDRESS wait type in SQL Server occurs when a query is waiting for the operating system to return the address of a specific function or routine. This wait type can be minimized by properly managing the use of external functions and routines, and by optimizing the performance of the external code itself. Applies to
