Creating a Mapping Table

To convert the user and object identifier numbers stored in the SQL trace files to their respective names, you need to provide a table that specifies each mapping. The SQL Performance Analyzer system will read this mapping table when converting the trace files into a SQL tuning set.

To create a mapping table:

• Run the following SQL statements on the production database:

  CREATE TABLE mapping AS
      SELECT object_id id, owner, SUBSTR(object_name, 1, 30) name FROM dba_objects
      WHERE object_type NOT IN ('CONSUMER GROUP', 'EVALUATION CONTEXT', 'FUNCTION',
                                'INDEXTYPE', 'JAVA CLASS', 'JAVA DATA',
                                'JAVA RESOURCE', 'LIBRARY', 'LOB', 'OPERATOR',
                                'PACKAGE', 'PACKAGE BODY', 'PROCEDURE', 'QUEUE',
                                'RESOURCE PLAN', 'SYNONYM', 'TRIGGER', 'TYPE',
                                'TYPE BODY')
      UNION ALL
      SELECT user_id id, username owner, null name FROM dba_users;
  

  Once the mapping table is created, you can use Data Pump to transport it to the SQL Performance Analyzer system.
