Preparation
• Get INVALID Objects:
SQL> SELECT UNIQUE object_name, object_type, owner
SQL> SELECT UNIQUE object_name, object_type, owner
• FROM dba_objects WHERE status='INVALID';
FROM dba_objects WHERE status='INVALID';
Recompile invalid objects in SYS and SYSTEM with utlrp.sql
• Compare invalid objects from before and after the upgrade
• Beginning with 11.1.0.7 the comparison has been automated
• registry$sys_inv_objs, registry$nonsys_inv_objs => utluiobj.sql
• Get accurate performance statistics
• Comparison: before ↔ after
• Time specific queries and batches
• Test upgrade of the database
• Functional tests
• Performance tests with real life loads!!!
Preparation
• Possibilities for performance analysis:
• STATSPACK – export Perfstat user!!!
• Note:394937.1 STATSPACK guide
• AWR - extract the AWR
• Do AWR diff reports comparing before/after upgrade
• Real Application Testing
• SQL Performance Analyzer
• Database Replay
Preparation
• Create dictionary statistics prior to the upgrade - otherwise
it will take significantly longer
SQL> EXECUTE dbms_stats.gather_schema_stats
SQL> EXECUTE dbms_stats.gather_schema_stats
('SYS',
('SYS',
options
options => 'GATHER',
=> 'GATHER',
estimate_percent
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
=> DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt
method_opt => 'FOR ALL COLUMNS SIZE AUTO',
=> 'FOR ALL COLUMNS SIZE AUTO',
cascade
cascade => TRUE);
=> TRUE);
• Detailed scripts can be found here:
Oracle® Database Upgrade Guide Appendix B
• Or in / :
SQL> EXECUTE dbms_stats.gather_dictionary_stats;
SQL> EXECUTE dbms_stats.gather_dictionary_stats;
Preparation
• Switch off DATABASE VAULT (if used/installed)
• Oracle® Database Vault Administrator's Guide: Appendix B
• Unix: (simplified)
• Relinking without Database Vault
[$ make -f ins_rdbms.mk dv_off ]
•
$ dvca -action disable ...
$ dvca -action disable ...
• Windows:
• Rename oradv10.dll in ORACLE_HOME\bin
• Upon restart:
$ dvca -action disable ...
$ dvca -action disable ...
• After upgrading relink with dv_on or rename the DLL and enable
Database Vault again:
$ dvca -action enable ...
$ dvca -action enable ...
Preparation
• Drop SYS.PLAN_TABLE$ and SYS.PLAN_TABLE
• See Note: 605317.1 and Note:736353.1
• Otherwise the component "Oracle Server" can be INVALID after
the upgrade
• Introduced with DBMS_SQLPA
• Steps to solve this issue if it has happened:
• @catplan.sql -- recreate the plan table
@dbmsxpln.sql -- reload dbms_xplan spec
@prvtxpln.plb -- reload dbms_xplan implementation
@prvtspao.plb -- reload dbms_sqlpa
Installation
• Space / resource requirements
• Software installation:
• 150-200 MB in /tmp or \TEMP necessary
•
Example: Linux
• Seed database: ≥ 1,6 GB
• Seed databases are always prebuilt EE databases with all options!!!
• RAM: ≥ 1GB
• Swapspace
• RAM between 513Mb and 2048Mb → 1.5x RAM
• RAM between 2049Mb and 8192Mb → 1x RAM
• RAM more than 8192Mb → 0.75x RAM
