Awr oracle

AWR (Automatic Workload Repository):What is AWR? AWR reports collects database performance statistics and metrics for analysis and tuning, shows the exact time spent in the database, and even saves session information.What is default interval period between two awr report ?By default, AWR automatically generates snapshots of the performance data once every hour and retains the statistics in the workload repository for 7 days.GUI ----> OEM (Oracle Enterprise Manager)Login to OEM ---> Administration Tag ----> Workload Section --->AUTOMATIC WORKLOAD REPOSITORYThe data in the snapshot interval is then analyzed by the Automatic Database Diagnostic Monitor (ADDM).How to Manage & change interval period for awr report ?There is two to modify or changes in AWR report.1. Manually ---> through DBMS_WORKLOAD_REPOSITORY plsql package2. GUI ----> OEM (Oracle Enterprise Manager)Login to OEM ---> Administration Tag ----> Workload Section --->AUTOMATIC WORKLOAD REPOSITHow to Interpreting with AWR report ?1. Load ProfileHere we know about Logical Read, Physical Read, Soft Parse, Hard Parse2. Instance Efficiency PercentagesIf your instance percentage show BUFFER CAHCE HIT RATIO is 100% it is not sign for your database is very fast and running smootly.3. Top 5 Timed EventsIt is very important section in AWR report.through this we can know most five wait event is effecting database performance.4. SQL StatisticsIt this section we will know about Execution time, cpu used, logical & physical read for top most sql statement.5.Advisory StatisticsIn this section we will get advice for PGA, BUFFER CACHE, SHARED POOL, JAVA POOL size for better performance. How to generate AWR Report from Back-endPrior Oracle 10g we use STATSPACK report to analyze instance health for performance. but now in 10g we use AWR(automatic workload repository) report to analyze Oracle Database health.How to generate AWR report ?It is very easy to generate AWR report in Oracle 10g.We have to run just one sql script to generate AWR report.There is TWO sql script to create AWR report.1. awrrpt.sqlIf we have only One Oracle Database then run awrrpt.sql sql script.2. awrrpti.sqlIf we have more than One Oracle Instance (Like RAC) then run awrrpti.sql script so that we can particular instance for awr report creation.Location of AWR report sql script$ORACLE_HOME/rdbms/adminHow to generate AWR Report from OEM Grid1. Choose the Database for which, AWR report to be generated2. Choose Performance -> Snaphosts -> Automatic Workload Repository -> Run AWR Report3.

Well as licenses for the Diagnostic Pack. Contact your local Oracle representative for details.PrerequisitesThe script is written using the BASH (Bourne-Again SHell) language and was designed to run on Linux-based systems such as Oracle Linux or Red Hat. It can however be run on Microsoft Windows systems with the use of the Cygwin Linux API (see later section for details). The bc (basic calculator) binary must be present in order for the script to execute successfully. Use a package manager tool such as yum to ensure that bc is present.DownloadYou can download the script from my GitHub repository here: input for the awr-parser.sh script is a set of AWR reports in TEXT format – not in the default HTML format, as this is too hard to parse. The more AWR reports you have, the better – and they should be consecutive reports (i.e. based on consecutive snapshots) if you want any subsequent graphs to be meaningful.I have a script for generating the relevant AWR reports in one single batch. You can find it here: AWR Generator.OutputThe output from awr-parser.sh is a CSV file, i.e. a file containing comma-separated values.The following information is captured in the output CSV file:Filename : The filename of the AWR ReportDatabase Name : The name of the databaseInstance Number : The instance number (used in RAC)Instance Name : The name of the instanceDatabase Version : The Oracle database software versionCluster : Y/N flag indicating if this is a RAC clusterHostname : The hostname of the database serverHost OS : The host operating system (only in 11g and above reports)Num CPUs : The number of CPU cores as determined by OracleServer Memory (GB) : The amount of physical memory in the database serverDB Block Size : The database block size (2k, 4k, 8k, 16k or 32k)Begin Snap : The starting snapshot IDBegin Time : The starting snapshot timestampEnd Snap : The ending snapshot IDEnd Time : The ending snapshot timestampElapsed Time (mins) : The elapsed time of the AWR ReportDB Time (mins) : The amount of CPU time spent on database user callsAverage Active Sessions : The average number of active foreground Oracle sessionsBusy Flag : Y/N flag to indicate if DB Time > Elapsed Time*NUM_CPUsLogical Reads/sec : The average number of logical reads per secondBlock Changes/sec : The average number of block changes per secondRead IOPS : The average read IOPS for the AWR periodData Write

Includes a restricted-use license of the Oracle Database Enterprise Edition for use only with the Oracle Management Repository as well as with the following complementary repositories used by Oracle Enterprise Manager: Always-on Monitoring Repository, AWR Warehouse, Ops Center, Real User Experience Insight, Load Testing, and Test Manager. Any use of Oracle Database options by Oracle Enterprise Manager's SYSMAN schema is included with the restricted-use license and does not require a separate license. Additional database options or additional servers for disaster recovery require separate licensing. Customers receive one single-instance database with the Cloud Control, or RMAN, repository. To protect the repository with Data Guard, customers need to purchase a license for the standby site. To protect the repository with Oracle Real Application Clusters, customers must license the second node for the database, and both nodes require an Oracle Real Application Clusters license. Use of Oracle WebLogic Server with Oracle Enterprise Manager is restricted to servlet functionality. A restricted-use license for WebLogic clustering is included, to support deployment of cluster of Oracle Business Intelligence Publisher servers, only when used with Oracle Enterprise Manager. Oracle Enterprise Manager includes restricted use of Oracle Business Intelligence Publisher (BI Publisher) and Business Intelligence Mobile for use with Oracle Enterprise Manager functions and interfaces only. This restricted BI Publisher license allows reporting only against the Oracle Enterprise Manager repository and against data dictionary (including AWR and AWR Warehousing data) of target databases. In order to report against other data sources, it is necessary to have the BI Publisher license. Note: Some Oracle Enterprise Manager management packs include BI Publisher reports that use a different data source. The license to use these reports is provided as part of the license for the relevant management pack. More details on these reports are provided in the relevant chapter of this document. Restricted-use license of Oracle ZFS Storage Appliance Cloning (Part #7102338) is included with Oracle Enterprise Manager Snap Clone, a feature of Oracle Cloud Management Pack for Oracle Database.
