These videos will be published in a seemingly random order, partly related to how I decide to edit/cut them.  Also there will be some differences in video/audio quality as I improve my processes over time.  The videos were not necessarily shot in the order of execution, but I will sequence them in a “Playlist” on youtube so it’s easy to figure out the order in which they should be watched.

Please keep in mind there will be gaps.  At present, I have put four new videos up; my intention is the following set of videos:

  1. Working with VMWare: Understanding guests, multiple virtual NICs, vmnet, vmdks, and the cloning process
  2. Install Oracle Enterprise Linux (OEL, RHEL, CentOS) 5.4 or 5.3 using a kickstart file to build a generic “base brick machine” (BBM)
  3. Understanding runlevels and booting into single user mode with GRUB and Linux
  4. Create an iSCSI target host using a BBM (not bloated openfiler)
  5. Create a router using a BBM to serve as a gateway and DHCP server for the public network of a RAC
  6. Create a DNS server using a BBM, and create zones for Oracle Grid Infrastructure GNS
  7. Install Oracle Enterprise Manager Grid Control 10.2.0.x and patch to 10.2.0.5 (10gR5) on a BBM
  8. Understanding ssh user equivalency and using the basics of authorized_keys
  9. Prepare a BBM for Oracle Grid Infrastructure 11g R2
  10. Install Oracle Grid Infrastructure 11g R2 in VMWare on 2 nodes
  11. Run root scripts for Oracle Grid Infrastructure 11g R2
  12. Install Oracle Database Real Application Clusters (RAC) 11g R2 on 2 nodes
  13. Creating a RAC 11g R2 database using DBCA

Arguably steps 4 and 9 are probably the most difficult for configuring a RAC; #4, creating the shared storage “device” (in this case, a server running OEL with iSCSI target software) and #9, attaching the nodes to this device.

The 4 videos I’ve prepared and uploaded so far:

4. Create an iSCSI target host using a BBM
9. Prepare a BBM for Oracle Grid Infrastructure 11g R2
10. Install Oracle Grid Infrastructure 11g R2 in VMWare on 2 nodes
11. Run root scripts for Oracle Grid Infrastructure 11g R2

The playlist that I will maintain with this full list of videos is at this link.

In less than 10 minutes of video, you will see the cloning of the Grid Infrastructure 11gR2 home, cloning of the Database 11gR2 home, and creation of a 4th instance all running in VMWare.

addNode.sh has changed slightly; it no longer seems to allow an interactive Oracle Universal Installer (OUI) run.

I hope you enjoy this video!

I will be adding a 4th node in VMWare to demonstrate how to add (and later remove) nodes and RAC instances in open databases.

These videos show how viable it can be to use VMWare to build a test RAC enviroment, even with the latest version, 11g R2, despite the system requirements espoused by Oracle. I take great pains to build the VMs and prep them for installation success, and I will later document all these processes and possibly create videos of the process too.

Please enjoy and let me know what you think!

Video 1 shows Grid Infrastructure installing on 3 VMWare nodes
Video 2 was destroyed when Camtasia decided to crash and leave no temp files behind; it was the installation of 11g R2 Database in RAC
Video 3 shows DBCA starting up
Video 4 shows 3 instances of the RAC database up and kicking
