Enabling Statspack for 11gR2 RAC
With 11g standard edition you can no longer buy the tuning and diagnostic packs so no awr reports so back to the old statspack, this is the steps i used to install statspack on my 2 node 11gR2 RAC cluster.
1. Create the perfstat schema
SQL> @?/rdbms/admin/spcreate Choose the PERFSTAT user's password ----------------------------------- Not specifying a password will result in the installation FAILING Enter value for perfstat_password: xxxxxx xxxxxx Choose the Default tablespace for the PERFSTAT user --------------------------------------------------- Below is the list of online tablespaces in this database which can store user data. Specifying the SYSTEM tablespace for the user's default tablespace will result in the installation FAILING, as using SYSTEM for performance data is not supported. Choose the PERFSTAT users's default tablespace. This is the tablespace in which the STATSPACK tables and indexes will be created. TABLESPACE_NAME CONTENTS STATSPACK DEFAULT TABLESPACE ------------------------------ --------- ---------------------------- SYSAUX PERMANENT * USERS PERMANENT Pressing will result in STATSPACK's recommended default tablespace (identified by *) being used. Enter value for default_tablespace: SYSAUX Using tablespace SYSAUX as PERFSTAT default tablespace. Choose the Temporary tablespace for the PERFSTAT user ----------------------------------------------------- Below is the list of online tablespaces in this database which can store temporary data (e.g. for sort workareas). Specifying the SYSTEM tablespace for the user's temporary tablespace will result in the installation FAILING, as using SYSTEM for workareas is not supported. Choose the PERFSTAT user's Temporary tablespace. TABLESPACE_NAME CONTENTS DB DEFAULT TEMP TABLESPACE ------------------------------ --------- -------------------------- TEMP TEMPORARY * Pressing will result in the database's default Temporary tablespace (identified by *) being used. Enter value for temporary_tablespace: TEMP Using tablespace TEMP as PERFSTAT temporary tablespace. ... Creating PERFSTAT user ... Installing required packages ... Creating views ...

4.Some useful statspak information
Statspack – the basic source of information is $ORACLE_HOME/rdbms/admin/spdoc.txt
spreport.sql -> Generates a Statspack Instance report
sprepins.sql -> Generates a Statspack Instance report for the database and instance specified
sprepsql.sql -> Generates a Statspack SQL report for the SQL Hash Value specified
sprsqins.sql -> Generates a Statspack SQL report for the SQL Hash Value specified, for the database and instance specified
sppurge.sql -> Purges a limited range of Snapshot Id’s for a given database instance
sptrunc.sql -> Truncates all Performance data in Statspack tables
spuexp.par -> An export parameter file supplied for exporting the whole PERFSTAT user
