PURPOSE ------- This note is intended to provide configuring and installing information about the StatsPack package. SCOPE & APPLICATION ------------------- This note is applicable for Oracle RDBMS releases 8.1.6 and greater, and is related to the task of gathering database and session level performance information. Configuration and Installation of the StatsPack Package. -------------------------------------------------------- - StatsPack Database Space Requirements Oracle does not recommend installing the package in the SYSTEM tablespace. A more appropriate tablespace (if it exists) would be a "TOOLS" tablespace. If you install the package in a locally-managed tablespace, storage clauses are not required, as the storage characteristics are automatically managed. If you install the package in a dictionary-managed tablespace, Oracle suggests you monitor the space used by the objects created, and adjust the storage clauses of the segments, if required. The default initial and next extent size is 1MB for all tables and indexes which contain changeable data. The minimum default space requirement is approximately 35MB. The amount of database space required by the package will vary considerably based on the frequency of snapshots, the size of the database and instance, and the amount of data collected (which is configurable). It is therefore difficult to provide general storage clauses and space utilization predictions which will be accurate at each site. - Installing the StatsPack package Interactive Installation: ======================== During the installation process, the user PERFSTAT will be created, default password PERFSTAT. This user will own all PL/SQL code and database objects created (including the STATSPACK tables, constraints and STATSPACK package). The installation SQL script will prompt for the PERFSTAT user's default and temporary tablespaces and also for the tablespace in which the tables and indexes will be created NOTE: o Do not specify the SYSTEM tablespace for the PERFSTAT users DEFAULT or TEMPORARY tablespaces; if SYSTEM is specified the installation will abort with an error indicating this is the problem. This is enforced as Oracle do not recommend using the SYSTEM tablespace to store statistics data, nor for sorting. Use a TOOLS tablespace to store the data, and your instance's TEMPORARY tablespace for sorting. o During the installation, the dbms_shared_pool and dbms_job PL/SQL packages are created. dbms_shared_pool is used to pin the Statspack package in the shared pool; dbms_job is created on the assumption the DBA will want to schedule periodic snapshots automatically using dbms_job. o The installation grants SELECT privilege to PUBLIC for all of the Statspack owned tables (prefixed by STATS$). Even though SVRMGRL is available with Oracle8i releases 8.1.6 and 8.1.7, installation of StatsPack can only be done with SQL*Plus do to special formatting commands that are used in the scripts. Oracle9i releases do not include SVRMGRL. FYI: ==== 1)Note:105692.1: "Installation of statspack fails from Server Manager", discusses this matter further. 2)BUG 2673074 Abstract: SPCREATE.SQL HANGS BUSY SYSTEM This may cause the database to hang while running the SPCREATE.SQL script. Workaround: Make sure all DBMS_* packages are compiled or manually comment out the creation of dbmsjob.sql from spcusr.sql To install the package, using SQL*Plus and based on the correct platform and RDBMS version, do the following: Oracle 8.1.6: on Unix: SQL> connect / as sysdba SQL> @?/rdbms/admin/statscre on NT: SQL> connect / as sysdba SQL> @%ORACLE_HOME%\rdbms\admin\statscre on VMS SQL> connect / as sysdba SQL> @ora_rdbms_admin:statscre Oracle8i 8.1.7 and Oracle9i 9.x on Unix: SQL> connect / as sysdba SQL> @?/rdbms/admin/spcreate on NT: SQL> connect / as sysdba SQL> @%ORACLE_HOME%\rdbms\admin\spcreate on VMS SQL> connect / as sysdba SQL> @ora_rdbms_admin:spcreate Oracle10g and 11g SQL> connect / as sysdba SQL> @?/rdbms/admin/spcreate on NT: SQL> connect / as sysdba SQL> @%ORACLE_HOME%\rdbms\admin\spcreate on VMS SQL> connect / as sysdba SQL> @ora_rdbms_admin:spcreate Although new tools are available for 10g and 11g such as AWR and ADDM, Statspack can also be used for 10g and 11g. Batch mode installation ======================= To install in batch mode, you must assign values to the SQL*Plus variables which specify the default and temporary tablespaces before running spcreate. The variables are: default_tablespace -> for the default tablespace temporary_tablespace -> for the temporary tablespace e.g. on Unix: SQL> connect / as sysdba SQL> define default_tablespace='tools' SQL> define temporary_tablespace='temp' SQL> @?/rdbms/admin/spcreate spcreate will no longer prompt for the above information. - Log files created during installation The StatsPack installation script runs 3 other scripts - you do not need to run these - the scripts are called automatically: Oracle8i 8.1.6 1. statscusr -> creates the user and grants privileges 2. statsctab -> creates the tables 3. statspack -> creates the package Oracle8i 8.1.7 or Oracle9i 9.x 1. spcusr -> creates the user and grants privileges 2. spctab -> creates the tables 3. spcpkg -> creates the package The installation script will generate spooled output file based on the name of the script being run and end with a 'lis' extension. Check each of the three output files produced by the installation to ensure no errors were encountered, before continuing on to the next step. For example, on Oracle8i 8.1.6, a output file called statcusr.lis will be created. Under Oracle8i 8.1.7 or Oracle9i 9.x, a output file spcusr.lis will be created. - Errors found during installation process If the scripts were incorrectly run while in SVRMGRL, an ORA-1012 error indicating that the session is not logged in or a PLS-00201 error indicating that stats$statspack_parameter must be declared may be generated. To correct this problem, first use SQL*Plus to remove StatsPack, and attempt installation using the above steps: Oracle 8.1.6: on Unix: SQL> connect / as sysdba SQL> @?/rdbms/admin/statsdrp on NT: SQL> connect / as sysdba SQL> @%ORACLE_HOME%\rdbms\admin\statsdrp on VMS SQL> connect / as sysdba SQL> @ora_rdbms_admin:statsdrp Oracle8i 8.1.7 and Oracle9i 9.x on Unix: SQL> connect / as sysdba SQL> @?/rdbms/admin/spdrop on NT: SQL> connect / as sysdba SQL> @%ORACLE_HOME%\rdbms\admin\spdrop on VMS SQL> connect / as sysdba SQL> @ora_rdbms_admin:spdrop Oracle 10g and 11g on Unix: SQL> connect / as sysdba SQL> @?/rdbms/admin/spdrop on NT: SQL> connect / as sysdba SQL> @%ORACLE_HOME%\rdbms\admin\spdrop on VMS SQL> connect / as sysdba SQL> @ora_rdbms_admin:spdrop - Batch mode installation There are two ways to install Statspack - interactively (as shown above), or in 'batch' mode (as shown below). Batch mode is useful when you do not wish to be prompted for the PERFSTAT user's default and temporary tablespaces. To install in batch mode, you must assign values to the SQL*Plus variables which specify the default and temporary tablespaces before running the StatsPack installation script. The variables are: default_tablespace -> for the default tablespace temporary_tablespace -> for the temporary tablespace e.g. on Unix: SQL> connect / as sysdba SQL> define default_tablespace='tools' SQL> define temporary_tablespace='temp' Oracle8i 8.1.6 SQL> @?/rdbms/admin/statscre Oracle8i 8.1.7 or Oracle9i 9.x SQL> @?/rdbms/admin/spcreate The StatsPack installation script will no longer prompt for the above information. Installing STATSPACK invalidates dbms_utility: ============================================== If dbms_job is already installed, then comment out the @@dbmsjob line in spcusr.sql.
