The Transaction Efficiency Analysis report in SQL Server Administration Studio helps you consider if In-Memory OLTP will improve your database software's performance. The report also indicates how much work you have to do to enable In-Memory OLTP in your software. After you determine a disk-based mostly table to port to In-Memory OLTP, you should use the Memory Optimization Advisor, that can assist you migrate the table. Similarly, the Native Compilation Advisor will assist you to port a saved procedure to a natively compiled saved process. For details about migration methodologies, MemoryWave Community see In-Memory OLTP - Widespread Workload Patterns and Migration Issues. The Transaction Performance Analysis report is run immediately against the manufacturing database, or a test database with an lively workload that is similar to the production workload. Analyze your workload to determine scorching spots the place In-Memory OLTP can probably assist to improve efficiency. The Transaction Efficiency Analysis report recommends tables and saved procedures that may benefit most from conversion to In-Memory OLTP. Help you plan and execute your migration to In-Memory OLTP.
The migration path from a disk primarily based desk to a memory-optimized desk will be time consuming. The Memory-Optimization Advisor helps you establish the incompatibilities in your table that you need to remove earlier than transferring the table 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 may have on your software. You can see if your utility would benefit from In-Memory OLTP, once you wish to plan your migration to In-Memory OLTP, and each time you're employed to migrate a few of your tables and stored procedures to In-Memory OLTP. The efficiency of a database system relies on a variety of factors, not all of which the transaction performance collector can observe and measure. Subsequently, the transaction efficiency evaluation report doesn't guarantee actual efficiency positive aspects will match its predictions, if any predictions are made. The Transaction Efficiency Analysis report and the migration advisors are installed as a part of SQL Server Administration Studio (SSMS) when you select Management Tools-Primary or Management Tools-Superior whenever you set up SQL Server, or once you Download SQL Server Management Studio.
You possibly can generate transaction performance analysis reports in Object Explorer by proper-clicking on the database, deciding on Stories, then Customary Reviews, after which Transaction Efficiency Evaluation Overview. The database needs to have an active workload, Memory Wave or a latest run of a workload, with a view to generate a meaningful evaluation report. This section includes a single table that exhibits the statistics that had been collected about scans on the database desk. Percent of complete accesses. The proportion of scans and seeks on this desk with respect to the exercise of the whole database. The upper this share, the extra heavily used the desk is compared to different tables in the database. Lookup Statistics/Range Scan Statistics. This column records the number of level lookups and range scans (index scans and table scans) conducted on the desk during profiling. Average per transaction is an estimate. This part includes a table that reveals contention on the database table.
For more data concerning database latches and locks, please see Locking Architecture. % of whole waits. The percentage of latch and lock waits on this database table compared to activity of the database. The upper this proportion, the extra heavily 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 table. For info on latches, see Latching. The upper this number, the extra latch contention on the desk. Lock Statistics. This group of columns document the number of web page lock acquisitions and waits for queries for this table. For extra data on locks, see Understanding Locking in SQL Server. The more waits, the more lock contention on the desk. This section features a table that exhibits the issue of converting this database table to a memory-optimized desk. A higher difficulty ranking signifies extra difficultly to transform the desk. To see details to convert this database table, please use the Memory Optimization Advisor.
