From Oracle FAQ Statspack is a set of performance monitoring and reporting utilities provided by Oracle starting from Oracle 8i and above. Statspack provides improved BSTAT/ESTAT functionality, though the old BSTAT/ESTAT scripts are still available. For more information about STATSPACK, read the documentation in file $ORACLE_HOME/rdbms/admin/spdoc.txt.Although AWR and ADDM (introduced in Oracle 10g) provide better statistics than STATSPACK, users that are not licensed to use the Enterprise Manager Diagnostic Pack should continue to use statspack.Install statspack[edit]cd $ORACLE_HOME/rdbms/adminsqlplus "/ as sysdba" @spdrop.sql -- Drop and install statspacksqlplus "/ as sysdba" @spcreate.sql -- Enter tablespace names when promptedTake performance snapshots of the database[edit]sqlplus perfstat/perfstatexec statspack.snap; -- Take a performance snapshots -- or instruct statspack to do gather more details in the snapshot -- (look up which oracle version supports which level).exec perfstat.statspack.snap(i_snap_level=>10); The spauto.sql script can be customized and executed to schedule the collection of STATPACK snapshots.Statspack reporting[edit]-- Get a list of snapshotsselect SNAP_ID, SNAP_TIME from STATS$SNAPSHOT; @spreport.sql -- Enter two snapshot id's for difference reportOther statspack scripts[edit]Some of the other statspack scripts are:spauto.sql - Schedules a dbms_job to automate the collection of STATPACK statisticsspcreate.sql - Installs the STATSPACK user, tables and package on a database (Run as SYS)spdrop.sql - Deinstalls STATSPACK from database (Run as SYS)sppurge.sql - Purges (deletes) a range of Snapshot Id's between the specified begin and end Snap Id'sspreport.sql - Reports differences between values recorded in two snapshotssprepsql.sql - Reports execution planssptrunc.sql - Truncates all data in Statspack tablesPotential problems[edit]Statpack reporting suffers from the following problems:Some statistics may only be reported on COMPLETION of a query. For example, if a query runs for 12 hours, its processing won't be reported during any of the snapshots taken while the query was busy executing.If queries are aged out of the shared pool, the stats from V$SQL are reset. This can throw off the delta calculations and even make it negative. For example, query A has 10,000 buffer_gets at snapshot 1, but at snapshot #2, it has been aged out of the pool and reloaded and now shows only 1,000 buffer_gets. So, when you run spreport.sql from snapshot 1 to 2, you'll get 1,000-10,000 = -9,000 for this query.External links[edit]OraPerf.com, upload your STATSPACK file to get performance recommendations - no more exists.www.spviewer.com, website with software tools for Oracle tuning based on statspack and AWR.

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.

All the information All the information is quickly accessible: details of the SQL query, execution plan, binding variables and more. The standard STATSPACK/AWR analyzer provided by Oracle corporation as a component of the Oracle database has to be executed as a script and only provides the output in the text form, which is complicated to read. Also, it is not possible to see SQL execution plan without creating new output. Text output is divided to several sections and to find the links between data user has to scroll between particular sections.AWR Analyzer plug-in presents data in a much more user-friendly GUI.More info…

Installing and Using Standby Statspack in 11g Installing and Using Standby Statspack in 11g (Doc ID 454848.1)APPLIES TO:Oracle Database - Enterprise Edition - Version 11.1.0.6 and laterInformation in this document applies to any platform.PURPOSEStatspack/AWR cannot be executed on a standby due to its read-only nature. Therefore tuning the performance of the apply process involves manually collecting statistics.In 11gR1, using the new Active Data Guard option, users can now use statspack from the primary database to collect data from a standby database that is opened read-only and performing recovery. The standby statspack is installed in a separate schema on the Primary database, STDBYPERF which is then propagated to the standby. This new user does not have DBA privileges and has no access to local V$ tables.SCOPEThis document applies to 11gR1 and up.DETAILS1. Standby Statspack Usage1.1 Statspack InstallationThe perfstat schema and statspack related objects must be present on the primary and standby prior to installing standby statspack. If the perfstat user does not exist in the primary site then you will need to create the perfstat schema using the following:sqlplus / as sysdbaSQL> @?/rdbms/admin/spcreate.sql The standby statspack installation script (sbcreate.sql) creates the standby statspack schema to hold the standby snapshots. The script asks for:A password for stdbyperf userDefault tablespaceTemporary tablespaceThe script creates the ‘stdbyperf’ user and assigns it the selected default and temporary table space. After the user has been created it calls sbaddins.sql to add the first standby instance to the configuration.Example:SQL> @?/rdbms/admin/sbcreateNote: Due to Bug 11899453, ensure global_names is set to 'FALSE' on the Standby Database while you run this Script. See Note 11899453.8 for some more Details.Ensure the Initialization Parameter 'open_cursors' is set to at least 100 on the Primary and Standby Database.1.2 Add an Instance to Statspack ConfigurationLog in to the primary as the 'stdbyperf' user and run the script sbaddins.sql to add a standby instance to the configuration. The script asks for:The TNS alias of the standby database instanceThe password of the perfstat user on the standby siteThe script then creates a private database link to the perfstat schema on the standby site and a separate gathering
