2. AGENDA Oracle Best Practices Oracle Backups Why upgrade to Oracle 11? Performance Troubleshooting axiUm Pre-Upgrade Checklist Questions

3. ORACLE BEST PRACTICES

4. Good tested backup Check alert log file for errors Collect Oracle statistics Check for invalid/unusable objects Monitor tablespaces for growth up to 32GB on Windows

5. Database auditing on maintenance tables only Move the Fine Grain Auditing table (sys.fga$) table to different tablespace from its default Ensure there is enough free space on server Truncate temporary axiUm tables (ptbal, ptbalbat, ptbalext, statemnt, stmtjob, pitemtmp) Manage growth of message and msgsent tables

6. Run DBV while database is not in use Defragment tablespaces (both Oracle and OS) Separate axiUm databases/schemas: – Production – Reports – Training – Testing

7. ORACLE BACKUPS

8. Export/Import Data Pump Cold or Off-line Backup Hot or On-line Backup RMAN Backup

9. Backup software libraries, parameter files, password files, etc If database is in ARCHIVELOG mode, backup archived log files as well http://docs.oracle.com/cd/E11882_01/backup.112/e106 42/rcmintro.htm http://docs.oracle.com/cd/E11882_01/backup.112/e106 42/rcmintro.htm

10. Why upgrade to Oracle 11?

11. Extended Oracle support for Oracle 10 ending on July 2013 There is a known bug in Oracle 10.2.0.4 which causes problem in axiUm messenger New Crystal engine in axiUm 5.1x (.NET) requires 11.1.0.7 or higher Oracle client version

12. Starting with Oracle client 11.2.0.3 OO4O has been deprecated. New DBEngine=5 (OCCI) will be available in 5.20 Oracle Database Version 11.2 Operating System 32-bit Oracle Database Server and Client 11.2.0.4 and higher Windows 8 (32-bit) 32-bit Oracle Database Client 11.2.0.4 and higher Windows 8 x64 32-bit Oracle Database Client 11.2.0.4 and higher Windows Server 2012 x64 64-bit Oracle Database Server and Client 11.2.0.4 and higher Windows 8 x64 64-bit Oracle Database Server and Client 11.2.0.4 and higher Windows Server 2012 x64

13. Tablespace encryption feature available in Oracle 11 (Enterprise Edition – extra cost) Oracle Advanced Compression available in Oracle 11 (Enterprise Edition)

14. PERFORMANCE TROUBLESHOOTING

15. Check OS resources (CPU, network) Check running SQL Check Scheduled Jobs Check Oracle parameters Check locked tables Check alert log file Use SQL Tuning Advisor to optimize SQL

16. axiUm PRE-UPGRADE CHECKLIST

17. 1. Take a good back up and know how much time it will take to restore if needed 2. Check all the datafiles/tablespaces for enough free space 3. Disable oracle archiving 4. If needed, increase undo and temporary tablespace 5. Check for invalid and unusable objects and rebuild them before upgrade

18. 6. Uncompress all the tables - send us the list of these tables 7. Disable your customized triggers (don't forget to enable them after the upgrade) 8. Change axium schema password and set LOGIN_ATTEMPTS to unlimited. 9. Give "kill session" privilege to axiUm user 10. Turn off database auditing (Maintenance – System tab) 11. Have an Oracle DBA available at your end during the upgrade
