DML Statements (nur im Linemode), die über ein SQL Tuning Set (kurz STS) zur Verfügung gestellt werden. If unspecified, the current or most recent trace file in the specified directory will be used. Once you create a workload (called a SQL Tuning Set, or STS), Oracle will repeatedly execute the workload, The concept of SQL tuning sets, along with the DBMS_SQLTUNE package to manipulate them, was introduced in Oracle 10g as part of the Automatic SQL Tuning functionality. directory-name, Create Experiment in a Group with -g The information generated by SQL Trace is stored in SQL trace files. Move the SQL trace files and the mapping table from the production system running Oracle Database 9i to the system running Oracle Database 11g. If you choose to use TEST EXECUTE, the SQL workload will be executed to completion. After tuning the regressed SQL statements, you should test these changes using SQL Performance Analyzer. All 50+ Adobe apps explained in 10 minutes - Duration: 10:10. The following example creates a SQL Performance Analyzer task named my_spa_task that will use the SQL tuning set named my_sts_9i as its input source: After the SQL Performance Analyzer task is created on the system running Oracle Database 11g, you need to call the EXECUTE_ANALYSIS_TASK procedure to take the execution plans and runtime statistics in the SQL tuning set and use them to build a pre-upgrade SQL trial. Oracle 11 ist zwar nicht brandneu, jedoch gibt es nach meiner Meinung immernoch viele offene Fragen was Oracle 11g alles mit sich bringt. Capture stored outlines on the production system and move them to the test system. It's a tricky one. The production system which you are upgrading from should be running Oracle Database 9i. Testing a system change on a production system will impact the system's throughput because SQL Performance Analyzer must execute the SQL statements that you are testing. copy, move, and delete experiments; add labels to experiments; and archive and export ORA-00911 From SQL Performance Analyzer Home When Using Underscore Parameter(_) for Parameter Change (Doc ID 2730297.1) Last updated on DECEMBER 18, 2020.

Performance Analyzer can also display metrics of performance for structures in the dataspace displays the data recorded by the Collector so that you can examine the information. Set order_by to specify an order-by clause on the selected SQL. The following example illustrates a function call: Call the DBMS_SQLPA.REPORT_ANALYSIS_TASK function to generate a report using the following parameters: Set the execution_name parameter to the name of the COMPARE PERFORMANCE execution. Using TEST EXECUTE is recommended to capture the SQL execution plans and performance data at the source, thereby resulting in a more accurate analysis. system is running a load. I have copied the sql tunning set over to the target, but how do I move over the original "SQL Tunning analysis" object(s). This functionality is provided so that you can use SQL Performance Analyzer to test the impact on SQL response time of a database upgrade from Oracle Database 9i to Oracle Database 10g Release 2, as illustrated in Figure 1-1. Chapter 5, er_print Command-Line Performance Analysis Set the execution_type parameter to CONVERT SQLSET to direct SQL Performance Analyzer to treat the statistics in the SQL tuning set as a trial execution.

This setting will analyze and compare two versions of SQL performance data. Tool, Chapter 6, Understanding Performance Analyzer and Its The syntax for the SELECT_SQL_TRACE function is as follows: Table 1-1 describes the available parameters for the SELECT_SQL_TRACE function. connect to a server where the full Oracle Solaris Studio product is installed and view experiments remotely. Specifies the schema where the mapping table resides. You can then copy the SQL trace files to the system running Oracle Database 11g. The following example executes the SQL Performance Analyzer task named my_spa_task as a trial execution: After the pre-upgrade SQL trial is built, you need to run a SQL Performance Analyzer task to perform a test execute or explain plan of SQL statements in the SQL tuning set on the test system running Oracle Database 10g Release 2 to build a post-upgrade SQL trial. Running SQL Performance Analyzer involves creating SQL trials for Oracle Database 9i and Oracle Database 10g Release 2, and storing them in a central task container. Data discusses topics related to understanding the Performance Analyzer and its data, Oracle Database 11g Release 1 (11gR1) features the new SQL Performance Analyzer that promises to ease significantly the workload of busy Oracle DBAs because it provides a way to accurately evaluate complete database workloads for “before versus after” performance changes. filename Execute the task to convert production statistics from the SQL tuning set into a pre-upgrade SQL trial, as described in "Building the Pre-Upgrade SQL Trial". The SQL tuning set will contain the SQL statements captured in the SQL trace files, along with their relevant execution context and statistics. of time. HOL 19c SQL Performance Analyzer - Instructions for the Oracle Database Upgrade 19c Hands-On Lab on how to use the SQL Performance Analyzer for analysis Oracle Solaris Studio 12.4 Information Library, Chapter 5, er_print Command-Line Performance Analysis It can help you to overcome a 100% copy of the production environment, and better still, and unlike ADRCI, SPA can be back ported to releases prior to 11g.My Oracle Support note 560977.1, ?Real Application Testing Now Available for Earlier Releases,? Oracle Database 11g Release 1 (11gR1) features the new SQL Performance Analyzer that promises to ease significantly the workload of busy Oracle DBAs because it provides a way to accurately evaluate complete database workloads for “before versus after” performance changes. After enabling SQL Trace on the production system running Oracle 9i, identify the SQL trace files containing statistics for a representative set of SQL statements that you want to use with SQL Performance Analyzer. Subsequent comparisons will only be able to yield a list of changed plans without making any conclusions about performance changes. Oracle Database PL/SQL Packages and Types Reference, Testing Database Upgrade from Oracle Database 9, Description of "Figure 1-1 SQL Performance Analyzer Workflow for Database Upgrade from Oracle Database 9i to Oracle Database 10g Release 2", "Creating a SQL Performance Analyzer Task".
