Oracle: using statspack

Use the steps as described in:
http://www.oracledistilled.com/oracle-database/performance/installing-and-configuring-statspack/
which are:
1) Create the tablespace to hold the Statspack tables.

CREATE TABLESPACE statspack_db_data DATAFILE 
  '/home/oracle/oracle/oradata/CRMMBQT/statspack_db_data_01.dbf' SIZE 500M AUTOEXTEND ON NEXT 10M MAXSIZE 2048M
EXTENT MANAGEMENT LOCAL uniform size 1M
SEGMENT SPACE MANAGEMENT AUTO;

2) Run the ORACLE_HOME/rdbms/admin/spcreate.sql script to create the PERFSTAT schema.

cd /home/oracle/oracle/product/11.2.0/dbhome_1/rdbms/admin
> sqlplus / as sysdba
SQL> @spcreate

A list of available table spaces will be presented. Type in the name of the table space created earlier and hit the enter key.
When selecting a temporary table space for the PERFSTAT user, keep the default tablespace as proposed.

3) Execute a snapshot w/ level 7:

exec statspack.snap(i_snap_level => 7);

4) Run a report:
ORACLE_HOME\rdbms\admin\spreport.sql is used to generate an instance level report.
You will then pick a beginning snapshot and an ending snapshot, as well as a file name to save results.

cd /home/oracle/oracle/product/11.2.0/dbhome_1/rdbms/admin
> sqlplus / as sysdba
SQL> @spreport
