This document specifically describes how to use SQL Performance Analyzer in a database upgrade from Oracle Database 9i to Oracle Database 10g Release 2. Powerful performance analysis tool for optimizing C, C++, Java, Scala and Fortran applications. Performance Analyzer. For complete information about SQL Performance Analyzer, and how to use it in other cases, see Oracle Database Performance Tuning Guide. Specifies the opening delimiting pattern of the trace file sections to consider. Specifies the name of the mapping table. experiment-name, Set Directory of Experiment with -d Performance Analyzer is used by other tools in the Oracle Solaris Studio analysis suite: Thread Analyzer uses it for examining thread analysis experiments. copy, move, and delete experiments; add labels to experiments; and archive and export Chapter 8, Manipulating Experiments describes how to In cases when only a few SQL statements have regressed, consider using one of the following tuning methods to implement a point solution for them: Run the SQL Tuning Advisor on the regressed SQL statements using the test system running Oracle Database 10g Release 2. Tool describes how to use the er_print command-line interface to analyze Set sqlset_owner to the owner of the SQL Tuning Set. Compare SQL performance and fix regressed SQL: SQL Performance Analyzer compares the performance of SQL statements read from the SQL tuning set during the pre-upgrade SQL trial to those captured from the remote test execution during the post-upgrade SQL trial. To create a mapping table, run the following SQL statements on the production database running Oracle Database 9i: Once the mapping table is created, you can use Data Pump to transport it to the system running Oracle Database 11g. % wildcards are supported for matching trace file names. The statistics are not cumulative, as is the case with other SQL tuning set data source table functions. Ein SQL Workload besteht dabei aus SELECT bzw. directory-name, Create Experiment in a Group with -g how to use the sample code with Performance Analyzer. This parameter is currently not used. User’s Guide for more information. If unspecified, the current or most recent trace file in the specified directory will be used. See Using Performance Analyzer Remotely for more Use the DBMS_SQLTUNE.SELECT_SQL_TRACE function to read the SQL statements from the SQL trace files. If you choose to use TEST EXECUTE, the SQL workload will be executed to completion. You will be using this system to build a SQL tuning set and to run SQL Performance Analyzer. Once the SQL trace files and mapping table are moved to the system running Oracle Database 11g, you can build a SQL tuning set using the DBMS_SQLTUNE package. Summary. By default, the report shows the top 100 SQL statements impacted by the system change. SQL tracing itself has an impact on the statistics generated. In summary, the SQL Performance Analyzer can be used to help validate or explore changes. The production system which you are upgrading from should be running Oracle Database 9i. option, Save the Command Output to a File with -O These metrics are classed into the Comparing SQL Trials For example, you can profile an application Specify two versions of SQL performance data using the execution_params parameters. For other possible parameters that you can set for comparison, see the description of the DBMS_SQLPA package in Oracle Database PL/SQL Packages and Types Reference. To ensure that the analysis made by SQL Performance Analyzer is accurate, this system should contain an exact copy of the production data found on the production system. User’s Guide describes how to use Thread Analyzer. Database Performance Analyzer Overview for Oracle Databases - Duration: 3:24. solarwindsinc 14,282 views. You will also need to install a one-off patch for this release. Use basic_filter to filter out SQL statements that you do not want to include in the trial. connect to a server where the full Oracle Solaris Studio product is installed and view experiments remotely. Oracle Solaris Studio 12.4: Thread Analyzer The following example performs a test execute of the SQL statements remotely over a database link: After the pre-upgrade and post-upgrade SQL trials are built, you can compare the pre-upgrade version of performance data (from the production system) to the post-upgrade version (from the test system) by calling the DBMS_SQLPA.EXECUTE_ANALYSIS_TASK procedure or function to run a comparison analysis. Performance Analyzer is a commercial utility software for software performance analysis for x86 or SPARC machines. Tool, Chapter 6, Understanding Performance Analyzer and Its 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 Specifies the options for the operation. All 50+ Adobe apps explained in 10 minutes - Duration: 10:10. deadlocks in experiments that you can generate specifically for examining these types of data. Wir schauen uns hier die (aus meiner Sicht) interessantesten Features von 11g an. Once the SQL workload is captured in the SQL trace files, disable SQL Trace on the production system running Oracle 9i. Analyzer running on a Linux machine. Share. menu in Performance Analyzer for detailed information about using the tool. Oracle Performance - SQL Performance Analyzer Guided Workflow Example The information generated by SQL Trace is stored in SQL trace files. 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. To minimize the performance impact on the production system and still be able to fully capture a representative set of SQL statements, consider enabling SQL Trace for only a subset of the sessions, for as long as required, to capture all important SQL statements at least once. Specifies the schema where the mapping table resides. A task is a database container for SQL Performance Analyzer execution inputs and results. The database link should exist on the system running Oracle Database 11g and connect to the test system running Oracle Database 10g Release 2. This effectively builds the post-upgrade performance data using the statistics and execution plans generated from the test system running Oracle Database 10g. On the system running Oracle Database 11g, use SQL Performance Analyzer to build a pre-upgrade SQL trial and a post-upgrade SQL trial: Convert the contents in the SQL tuning set into a pre-upgrade SQL trial that will be used as a baseline for comparison. Therefore, any regression detected after comparing the SQL performance should be addressed before upgrading your production system. It can profile C, C++ and Java.. Performance tuning in Oracle databases includes optimizing SQL statements and query execution plans so that the requests can be completed more efficiently. SQL Performance Analyzer. Before creating the task, ensure that the SQL workload to use for the performance analysis is available in the form of a SQL tuning set on the system. file, Add a Comment to the Experiment with -C You can then repeat the process of executing the SQL tuning set and comparing its performance to a previous execution to test any fixes or additional changes made. Once you create a workload (called a SQL Tuning Set, or STS), Oracle will repeatedly execute the workload, DML Statements (nur im Linemode), die über ein SQL Tuning Set (kurz STS) zur Verfügung gestellt werden. Data provides an understanding of the annotated source and disassembly, providing Consequently, performance data for the Oracle Database 9i trial may appear worse than actual. Verwenden Sie Oracle Performance Analyzer, um die Nutzung von Oracle Database in Ihrer .NET-Anwendung per einfachem Klick auf eine Schaltfläche zu optimieren. The following example reads the contents of SQL trace files stored in the sql_trace_prod directory object and loads them into a SQL tuning set. The test system which you are upgrading to should be running Oracle Database 10g Release 2. If not specified, it will be generated by SQL Performance Analyzer and returned by the function. The Advisor Central page appears. 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. of time.
