Setup of ODA

6. Setup of ODA
6 04/10/16
Prerequisites
– Make customer download and use offline configurator to create a starting point
– Make customer be prepared for DNS configuration (SCAN)
– Ethernet Switches do not need a special patching – should provide hub functionality
– Client Workstation, if possible Windows with Java 7, needs an IP (optional DNS) too
– ILOM IPs should be reachable, for tests, there is not benefit of an admin lan
– Try to get all the Core Key Files in advance, start with minimum cores
– Download all related bundle patches and clone files of last and last but one version

7. Setup of ODA
7 04/10/16
Make customer start with BMR of latest version – 1 to be able to do patching

8. 8 04/10/16
Test Plan

9. Test Plan
9 04/10/16
Customer Brainstorming leads to …
• introduce GI features if necessary
• patching
• multiple Oracle Homes
• restart DBs at different node
• applying Core Keys
• 3 KPIs
Try to introduce your favorites
Try to convert your insights into later projects

10. Test Plan
10 04/10/16
Enrich Customer Brainstorming with Test Plan Outline (Doc ID 1474273.1)
Test Case 1 - Simulate failures to Internal (OS) disks
Test Case 2 - HDD (Hard Disk Drive) failure
Test Case 3 - SDD (Solid State Disk) failure
Test Case 4 - Connectivity to Database
Test Case 5 - Connection failover and continued service availability
Test Case 6 - Private network failure
Test Case 7 - Public Network Failure
Test Case 8 - Database backup and recovery test

11. 11 04/10/16
Maintenance / Integration

12. Maintenance / Integration
12 04/10/16
Make customer aware of search string “ODA”
Install additional Oracle_Homes
Build databases in each home
Do a complete patch cycle
If you clone Production to ODA from NFS Mount
– adjust parameters
– adjust size and location of redo logs
Preferrable: Data Pumpt Import
Transfere statistics if necessary
Integrate the ODA to (your) Cloud Control

13. Maintenance / Integration
13 04/10/16
Mistakes at Customer Site
Storage was powered off – Validating Storage did not show errors
Infiniband Interconnect was not selected in configurator
Linux Upgrade failed – Servers did not boot anymore
– “Tried to locate /boot/vmlinuz-26.39-400.264.13.el6uek.x86_64”

14. 14 04/10/16
Performancetests

15. Performancetests
15 04/10/16
Customer Case:
Planned KPI’s were 3 Batch Jobs
– Transform tables post load from production DB
– Rebuild MVs
– Swingbench Benchmarking
Customer wanted to use ODA as consolidation platform, means no moving datafiles to
SSD / Flash

16. Performancetests
16 04/10/16
Storage Setup at Customer Site: EMC VNX 5400
Blau = SAS Flash 16 x 200GB
Gelb = SAS 100 x 300GB
Grün = NL SAS 50 x 2TB

18. Performancetests
18 04/10/16
to get an overview of the expected results
– Database Appliance Administration and Reference Guide
• Database Sizing for Oracle Database Appliance
for troubleshooting
ODA: Whitepaper „Evaluating and Comparing Oracle Database Appliance Performance“

19. 19 04/10/16
Lessons learned

20. Lessons learned
20 04/10/16
Try to get core keys in advance
Check the competing DB – if you are not sure to win then prepare the customer
Keep ODA parameters during clone
Check Known Issues carefully
Change your role if necessary – means, if ODA fails:
– Make the customer aware that you did do a good job:
• integration support
• Validating KPI
