The Transaction Performance Evaluation report in SQL Server Administration Studio helps you evaluate if In-Memory OLTP will improve your database software's performance. The report also indicates how a lot work you will need to do to enable In-Memory OLTP in your application. After you determine a disk-based mostly desk to port to In-Memory OLTP, you need to use the Memory Optimization Advisor, to help you migrate the table. Equally, the Native Compilation Advisor will enable you to port a saved procedure to a natively compiled saved procedure. For information about migration methodologies, see In-Memory OLTP - Widespread Workload Patterns and Migration Concerns. The Transaction Efficiency Evaluation report is run immediately against the production database, or a check database with an energetic workload that's much like the manufacturing workload. Analyze your workload to find out sizzling spots the place In-Memory OLTP can doubtlessly help to enhance efficiency. The Transaction Performance Analysis report recommends tables and saved procedures that may benefit most from conversion to In-Memory OLTP. Aid you plan and execute your migration to In-Memory OLTP.
The migration path from a disk primarily based desk to a memory-optimized table will be time consuming. The Memory-Optimization Advisor helps you identify the incompatibilities in your desk that you have to remove before shifting the desk to In-Memory OLTP. The Memory-Optimization Advisor additionally helps you understand the impact that the migration of a table to a memory-optimized desk will have in your application. You can see in case your software would benefit from In-Memory OLTP, while you want to plan your migration to In-Memory OLTP, and every time you work to migrate some of your tables and saved procedures to In-Memory Wave Program 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. Subsequently, the transaction performance analysis report does not guarantee precise performance gains will match its predictions, if any predictions are made. The Transaction Performance Analysis report and the migration advisors are installed as part of SQL Server Management Studio (SSMS) when you choose Administration Tools-Basic or Administration Instruments-Superior if you set up SQL Server, or if you Obtain SQL Server Management Studio.
You can generate transaction efficiency analysis stories in Object Explorer by proper-clicking on the database, deciding on Stories, then Commonplace Studies, and then Transaction Efficiency Evaluation Overview. The database needs to have an energetic workload, or a recent run of a workload, as a way to generate a significant evaluation report. This part features a single table that exhibits the statistics that were collected about scans on the database table. % of total accesses. The share of scans and seeks on this table with respect to the exercise of the entire database. The upper this proportion, the more closely used the desk is in comparison with different tables in the database. Lookup Statistics/Vary Scan Statistics. This column records the variety of point lookups and vary scans (index scans and table scans) carried out on the desk throughout profiling. Average per transaction is an estimate. This section features a table that reveals contention on the database table.
For more data regarding database latches and locks, please see Locking Architecture. P.c of total waits. The percentage of latch and lock waits on this database table compared to activity of the database. The higher this percentage, the extra closely used the desk is compared to other tables in the database. Latch Statistics. These columns report the number of latch waits for queries involving for this desk. For info on latches, see Latching. The upper this number, the extra latch contention on the table. Lock Statistics. This group of columns record the variety of web page lock acquisitions and waits for queries for this table. For extra info on locks, see Understanding Locking in SQL Server. The extra waits, the extra lock contention on the table. This section includes a table that reveals the issue of converting this database table to a memory-optimized desk. A better problem score signifies more difficultly to transform the desk. To see particulars to convert this database table, please use the Memory Optimization Advisor.
