The Transaction Efficiency Analysis report in SQL Server Administration Studio helps you consider if In-Memory OLTP will enhance your database utility's performance. The report additionally indicates how much work you have to do to enable In-Memory OLTP in your application. After you identify a disk-primarily based table to port to In-Memory Wave Audio OLTP, you need to use the Memory Optimization Advisor, that can assist you migrate the desk. Similarly, the Native Compilation Advisor will enable you to port a stored process to a natively compiled stored process. For information about migration methodologies, see In-Memory OLTP - Common Workload Patterns and Migration Considerations. The Transaction Efficiency Evaluation report is run immediately towards the manufacturing database, or a take a look at database with an energetic workload that's just like the manufacturing workload. Analyze your workload to find out sizzling spots the place In-Memory OLTP can probably assist to enhance efficiency. The Transaction Efficiency Evaluation report recommends tables and stored procedures that may profit most from conversion to In-Memory OLTP. Enable you to plan and execute your migration to In-Memory OLTP.
The migration path from a disk based mostly desk to a memory-optimized desk can be time consuming. The Memory-Optimization Advisor helps you determine the incompatibilities in your table that you have to take away before moving the desk to In-Memory OLTP. The Memory-Optimization Advisor also helps you perceive the impact that the migration of a desk to a memory-optimized table could have on your utility. You'll be able to see in case your utility would benefit from In-Memory OLTP, once you wish to plan your migration to In-Memory OLTP, Memory Wave Audio and each time you're employed to migrate some of your tables and stored procedures to In-Memory OLTP. The performance of a database system relies on a selection of factors, not all of which the transaction efficiency collector can observe and measure. Due to this fact, the transaction efficiency evaluation report doesn't guarantee precise efficiency good points will match its predictions, if any predictions are made. The Transaction Efficiency Evaluation report and the migration advisors are put in as a part of SQL Server Management Studio (SSMS) when you select Administration Instruments-Basic or Administration Tools-Advanced if you set up SQL Server, or if you Download SQL Server Administration Studio.
You may generate transaction performance evaluation reviews in Object Explorer by proper-clicking on the database, Memory Wave deciding on Reviews, then Standard Studies, after which Transaction Performance Analysis Overview. The database must have an energetic workload, or Memory Wave a current run of a workload, to be able to generate a meaningful evaluation report. This section features a single desk that exhibits the statistics that have been collected about scans on the database table. % of total accesses. The percentage of scans and seeks on this table with respect to the exercise of your entire database. The higher this percentage, the extra heavily used the desk is compared to different tables in the database. Lookup Statistics/Vary Scan Statistics. This column information the variety of level lookups and range scans (index scans and desk scans) carried out on the desk during profiling. Average per transaction is an estimate. This part features a desk that exhibits contention on the database table.
For extra info concerning database latches and locks, please see Locking Structure. P.c of whole waits. The proportion of latch and lock waits on this database table compared to exercise of the database. The upper this proportion, the more heavily used the desk is compared to other tables within the database. Latch Statistics. These columns record the variety of latch waits for queries involving for this table. For information on latches, see Latching. The upper this quantity, the more 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 information on locks, see Understanding Locking in SQL Server. The more waits, the extra lock contention on the table. This part features a table that shows the difficulty of changing this database desk to a memory-optimized desk. A higher difficulty ranking signifies extra difficultly to convert the desk. To see details to transform this database table, please use the Memory Optimization Advisor.
