Determining if a Table or Stored Process Needs to be Ported To In-Memory OLTP > 자유게시판

The Transaction Efficiency Analysis report in SQL Server Management Studio helps you consider if In-Memory OLTP will enhance your database utility's performance. The report additionally signifies how much work you must do to allow In-Memory OLTP in your application. After you establish a disk-based table to port to In-Memory OLTP, you should utilize the Memory Optimization Advisor, that will help you migrate the table. Similarly, the Native Compilation Advisor will enable you to port a saved procedure to a natively compiled stored procedure. For information about migration methodologies, see In-Memory OLTP - Widespread Workload Patterns and Migration Concerns. The Transaction Performance Evaluation report is run straight in opposition to the production database, or a take a look at database with an active workload that is much like the production workload. Analyze your workload to find out hot spots where In-Memory OLTP can probably help to enhance efficiency. The Transaction Efficiency Evaluation 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 table to a memory-optimized table might be time consuming. The Memory-Optimization Advisor helps you identify the incompatibilities in your table that you need to remove before moving the desk to In-Memory OLTP. The Memory-Optimization Advisor additionally helps you perceive the impression that the migration of a table to a memory-optimized table will have in your application. You possibly can see if your software would profit from In-Memory OLTP, while you wish to plan your migration to In-Memory OLTP, and at any time when you're employed to migrate some of your tables and stored procedures to In-Memory OLTP. The efficiency of a database system relies on a selection 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 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 part of SQL Server Management Studio (SSMS) when you choose Management Instruments-Fundamental or Administration Instruments-Advanced whenever you install SQL Server, or when you Obtain SQL Server Management Studio.

You possibly can generate transaction performance evaluation studies in Object Explorer by right-clicking on the database, deciding on Reports, then Normal Stories, after which Transaction Performance Analysis Overview. The database needs to have an lively workload, cognitive enhancement tool or a recent run of a workload, with the intention to generate a meaningful evaluation report. This part features a single desk that exhibits the statistics that had been collected about scans on the database table. P.c of complete accesses. The percentage of scans and seeks on this desk with respect to the activity of the complete database. The upper this share, cognitive enhancement tool the extra closely used the desk is compared to other tables within the database. Lookup Statistics/Vary Scan Statistics. This column data the number of point lookups and range scans (index scans and table scans) conducted on the table during 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, please see Locking Architecture. Percent of whole waits. The proportion of latch and lock waits on this database table in comparison with exercise of the database. The higher this share, the extra closely used the table is in comparison with other tables in the database. Latch Statistics. These columns record the variety of latch waits for queries involving for this desk. For data on latches, see Latching. The higher this quantity, the extra latch contention on the desk. Lock Statistics. This group of columns report the number of web page lock acquisitions and waits for queries for this table. For more info on locks, see Understanding Locking in SQL Server. The extra waits, the extra lock contention on the desk. This part includes a desk that shows the problem of converting this database desk to a memory-optimized desk. A better problem rating signifies extra difficultly to convert the desk. To see particulars to convert this database desk, please use the Memory Optimization Advisor.
