The Transaction Performance Analysis report in SQL Server Management Studio helps you consider if In-Memory OLTP will improve your database software's performance. The report also indicates how much work you will need to do to enable In-Memory OLTP in your application. After you establish a disk-based table to port to In-Memory OLTP, you should use the Memory Optimization Advisor, that will help you migrate the desk. Similarly, the Native Compilation Advisor will aid you port a saved process to a natively compiled stored process. For details about migration methodologies, see In-Memory OLTP - Common Workload Patterns and Migration Issues. The Transaction Efficiency Evaluation report is run instantly in opposition to the manufacturing database, or a test database with an active workload that's much like the production workload. Analyze your workload to determine hot spots the place In-Memory Wave focus enhancer OLTP can potentially assist to improve efficiency. The Transaction Efficiency Evaluation report recommends tables and saved procedures that might 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 table could be time consuming. The Memory-Optimization Advisor helps you establish the incompatibilities in your table that you must remove before transferring the desk to In-Memory OLTP. The Memory-Optimization Advisor additionally helps you understand the impression that the migration of a desk to a memory-optimized table may have in your utility. You can see if your application would profit from In-Memory OLTP, when you wish to plan your migration to In-Memory OLTP, and at any time when you work to migrate a few of your tables and stored procedures to In-Memory OLTP. The performance of a database system depends on a variety of factors, not all of which the transaction performance collector can observe and measure. Due to this fact, the transaction performance analysis report does not guarantee actual performance good points will match its predictions, if any predictions are made. The Transaction Performance Evaluation report and the migration advisors are put in as part of SQL Server Management Studio (SSMS) when you select Management Tools-Fundamental or Administration Instruments-Advanced once you install SQL Server, or if you Obtain SQL Server Administration Studio.
You'll be able to generate transaction performance analysis reviews in Object Explorer by right-clicking on the database, choosing Experiences, then Commonplace Studies, after which Transaction Performance Evaluation Overview. The database needs to have an energetic workload, or a latest run of a workload, with the intention to generate a significant evaluation report. This part features a single table that reveals the statistics that have been collected about scans on the database table. Percent of complete accesses. The share of scans and seeks on this desk with respect to the activity of your complete database. The higher this proportion, Memory Wave focus enhancer the extra closely used the table is in comparison with different tables within the database. Lookup Statistics/Range Scan Statistics. This column records the number of point lookups and vary scans (index scans and table scans) carried out on the table throughout profiling. Common per transaction is an estimate. This part features a table that reveals contention on the database table.
For extra data regarding database latches and locks, please see Locking Structure. P.c of total waits. The percentage of latch and lock waits on this database desk in comparison with activity of the database. The upper this percentage, the extra heavily used the table is in comparison with different tables in the database. Latch Statistics. These columns record the number of latch waits for queries involving for this table. For info on latches, see Latching. The upper this quantity, the extra latch contention on the desk. Lock Statistics. This group of columns document the number of page lock acquisitions and waits for queries for this table. For Memory Wave more info on locks, see Understanding Locking in SQL Server. The extra waits, the more lock contention on the desk. This part features a table that shows the issue of changing this database desk to a memory-optimized desk. A better issue score indicates extra difficultly to convert the table. To see particulars to convert this database desk, please use the Memory Optimization Advisor.
