Determining if a Desk or Stored Process Ought to be Ported To In-Memory OLTP

The Transaction Performance Analysis report in SQL Server Administration Studio helps you evaluate if In-Memory OLTP will enhance your database utility’s efficiency. The report also indicates how a lot work you need to do to enable In-Memory OLTP in your application. After you determine a disk-primarily based table to port to In-Memory OLTP, you need to use the Memory Optimization Advisor, to help you migrate the table. Similarly, the Native Compilation Advisor will assist you to port a stored process to a natively compiled stored process. For details about migration methodologies, see In-Memory OLTP – Widespread Workload Patterns and Migration Considerations. The Transaction Efficiency Evaluation report is run directly against the production database, or a test database with an energetic workload that’s similar to the production workload. Analyze your workload to find out sizzling spots where In-Memory OLTP can probably help to enhance performance. The Transaction Efficiency Analysis report recommends tables and saved procedures that will benefit most from conversion to In-Memory OLTP. Allow you to plan and execute your migration to In-Memory OLTP.

The migration path from a disk primarily based desk to a memory-optimized desk can be time consuming. The Memory-Optimization Advisor helps you establish the incompatibilities in your table that you have to take away before transferring the desk to In-Memory OLTP. The Memory-Optimization Advisor additionally helps you perceive the impression that the migration of a desk to a memory-optimized table will have on your software. You may see if your software would profit from In-Memory OLTP, once you wish to plan your migration to In-Memory OLTP, and every time you’re employed to migrate a few of your tables and stored procedures to In-Memory OLTP. The performance of a database system is dependent on a selection of factors, not all of which the transaction performance collector can observe and measure. Due to this fact, the transaction performance evaluation report does not assure precise efficiency features will match its predictions, if any predictions are made. The Transaction Performance Analysis report and the migration advisors are installed as a part of SQL Server Management Studio (SSMS) when you choose Management Tools-Fundamental or Administration Tools-Advanced whenever you set up SQL Server, or while you Obtain SQL Server Administration Studio.

You possibly can generate transaction performance evaluation experiences in Object Explorer by proper-clicking on the database, selecting Studies, then Commonplace Studies, after which Transaction Efficiency Evaluation Overview. The database must have an energetic workload, or a latest run of a workload, as a way to generate a significant analysis report. This section features a single desk that exhibits the statistics that were collected about scans on the database table. % of complete accesses. The percentage of scans and seeks on this desk with respect to the exercise of the entire database. The upper this proportion, the more heavily used the desk is in comparison with different tables within the database. Lookup Statistics/Vary Scan Statistics. This column records the number of level lookups and range scans (index scans and table scans) conducted on the desk throughout profiling. Average per transaction is an estimate. This section features a desk that exhibits contention on the database table.

For extra information regarding database latches and locks, MemoryWave Focus Audio please see Locking Structure. % of whole waits. The percentage of latch and lock waits on this database desk in comparison with activity of the database. The upper this proportion, the extra heavily used the table is in comparison with different tables in the database. Latch Statistics. These columns document the number of latch waits for queries involving for this table. For data on latches, see Latching. The higher this number, the extra latch contention on the desk. Lock Statistics. This group of columns record the number of page lock acquisitions and waits for queries for this desk. For MemoryWave Focus Audio extra info on locks, see Understanding Locking in SQL Server. The extra waits, the extra lock contention on the table. This part features a table that exhibits the difficulty of converting this database table to a memory-optimized table. A higher issue score indicates more difficultly to transform the desk. To see details to convert this database table, please use the Memory Optimization Advisor.
