Setup of ODA




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




Setup of ODA

7 04/10/16

Make customer start with BMR of latest version – 1 to be able to do patching




8 04/10/16

Test Plan




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




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 04/10/16

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 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 04/10/16

Performancetests




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




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

Lessons learned




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

04/10/16 Name Presentation 21

INFOBOX – Read and delete •  There are two versions of the last slide

available, one for the contact details of a speaker, and one for two or more speakers.

•  Name, title and location always underneath one another in one row (Shift+Return)

•  This idea is that this is the last slide (also for questions and answers) and is on the screen for a long time at the end of the presentation, so the viewers have the chance to write down the contact data J
