Deploying Templates with Oracle Restart on OVM

I decided to post this after investigating how to use these templates in our demo room setup. You would think it’s straight forward but it appears the deploycluster tool, used to deploy these templates, is not yet compatible with OVM 3.3.1 and higher. That surprised me because it has been out for 3+ months now and with Oracle putting the emphasis on templates, it is strange that they do not work out of the box with the 2 most recent OVM versions. ( 3.3.1 & 3.3.2 )

Preparing the template

Let’s start with preparing everything for deployment

  • Download the template on oracle support patch nr: 18888811
    1
  • Unzip the 3 files resulting in 3 *.gz files
  • Join file 2A and 2B together
    (root) # cat OVM_OL6U6_X86_64_12102DBRAC_PVM-2of2-partA.tar.gz  OVM_OL6U6_X86_64_12102DBRAC_PVM-2of2-partB.tar.gz > OVM_OL6U6_X86_64_12102DBRAC_PVM-2of2.tar.gz
  • Place file 1 and the newly joined file 2 on a webserver ready for import into OVM.
  • Import the template
    2

Creating the VM

Follow the readme to create a VM, I decided to use 2 ASM disks in 1 diskgroup instead of the minimum of 5. I’m also deploying the oracle restart and not the RAC at this time.

  • Create the disks needed for ASM
    3
  • Create the VM based on the template
    4
  • Edit the VM and remove a network card, the second card is normally for interconnect in a rac deployment.
    5
  • Add the newly created disks to the VM
    7

Deploying it with deploycluster tool

  • Download the DeployCluster Tool
  • Place it on any linux machine, I normally place it on the OVM manager because of why not.
  • Configure netconfig.ini, start the VM and run the tool
    (root) # ./deploycluster.py -u admin -p password -M BNS -N netconfig.ini
    INFO: Oracle VM Client  (3.2.9.746) protocol (1.9) CONNECTED (tcp) to
          Oracle VM Manager (3.3.1.1065) protocol (1.10) IP (10.100.23.6) UUID (0004fb00000100008948135041eef83e)
    
    ERROR: This deploycluster.py version (v2.1.0) does not support connecting to Oracle VM Manager higher than 3.2; found Oracle Manager version 3.3. See My Oracle Support Note #1185244.1 and OTN for deployment options on this version.

So we see here there is a problem with compatibility. If we go to the mentioned note we see :

The Deploycluster tool currently only supports Oracle VM version 3.2 and below
Manual or Message based deployment is possible on Oracle VM 3.3.1

But no guidelines on manual deployment.

Deploying it with message based or manual deployment

  • Download and install ovm_utils on the ovm manager ( Patch: 13602094 )
  • Boot the VM and send the necessary messages ( or open console and do it manually ), KEYS :
    • com.oracle.racovm.netconfig.arguments => “-n1”
    • com.oracle.racovm.netconfig.contents.0 => send the content of netconfig.ini, this is for initial network setup
    • com.oracle.racovm.params.contents.0 => send the content of params.ini, we’ll leave this empty for now
    • com.oracle.racovm.racowner-password => password for oracle user
    • com.oracle.racovm.racowner-password => password for grid user
    • com.oracle.linux.root-password => password for root user
    • com.oracle.racovm.netconfig.interview-on-console => NO ( do not boot with the rac interview screen )

    Results in :

    export CMD="/u01/app/oracle/ovm-manager-3/ovm_utils/ovm_vmmessage -h 10.100.23.6 -u admin -p password -v BNS"
    
    $CMD -k "com.oracle.racovm.netconfig.arguments" -V "-n1"
    $CMD -k "com.oracle.racovm.netconfig.contents.0" -V "
    # Sample Single Instance or Single Instance/HA (Oracle Restart)
    NODE1=BNS
    NODE1IP=10.100.23.161
    PUBADAP=eth0
    PUBMASK=255.255.255.0
    PUBGW=10.100.23.254
    DOMAINNAME=labo.exitas  # May be blank
    DNSIP=10.100.23.20  
    CLONE_SINGLEINSTANCE_HA=yes  # Setup Single Instance/HA (Oracle Restart)"
    $CMD -k "com.oracle.racovm.params.contents.0"  -V ""
    $CMD -k "com.oracle.racovm.racowner-password" -V "oracle"
    $CMD -k "com.oracle.racovm.gridowner-password" -V "oracle"
    $CMD -k "com.oracle.linux.root-password" -V "ovsroot"
    $CMD -k "com.oracle.racovm.netconfig.interview-on-console" -V "NO"
    
  • Run the script and the machine will boot with a complete functional network
  • Logon as root with the previous specified password
  • Open /u01/racovm/params.ini and modify it for our environment, this file is very well commented and clearly explains every parameter, go wild 😉
    • Change GIHOME and DBHOME ( do not forget to move the clone files on the vm aswell if you change it )
    • Change the ASM settings, because we work with 2 disks
      RACASMDISKSTRING="/dev/xvd[c-d]1"
      ALLDISKS="/dev/xvdc /dev/xvdd"
      ASM_MIN_DISKS=2
    • Change DBNAME and SIDNAME
  • When you are done, perform the build :
    # ./buildsingle.sh
    Are you sure you want to install Single Instance/HA? YES
    Do not run if software is already installed and/or running.. [yes|no]? yes
    ...
    INFO (node:BNS): This entire build was logged in logfile: /u01/racovm/buildsingle.log
    2015-03-13 05:20:11:[buildsingle:Done :BNS] Building 12c Single Instance/HA
    2015-03-13 05:20:11:[buildsingle:Time :BNS] Completed successfully in 1052 seconds (0h:17m:32s)
    

That’s it, We deployed a VM with Oracle Restart and a 12c database with ease.

News from Oracle Open World 2012

I’m just back from OOW and the following is a small summary of the items that were hot and new.

Clusterware 12c announced for 2013

  • Flexasm : ASM no longer needs to be on the same node as the database. Allows for HA on ASM level.
  • Flexcluster : Clusterware now has a lightweight mode in the installer for application/middletier setups. You can combine these with the normal clusterware mode to form 1 big cluster. ( hub nodes and leaf nodes )
  • You can now create a Scan vip for each public network.
  • gsd service is removed because there is no support for 9i databases on clusterware 12c.
  • Shared GNS : You can now have a shared GNS over multiple clusters.

Database 12c announced for 2013

  • RAC Application Continuity : First ever database to preserve commit outcome and ensure application continuity during unplanned downtime.
  • Pluggable Databases : Databases can now be plugged in a container. Consolidating the background processes, redo and undo.
  • Xstream : A GUI on streams apply/capture processes is further enhanced but only available when you have Golden Gate license.
  • dbua : now has backup/restore and moving database files during upgrade built in.
  • dbua : Gathering statistics is now optional.
  • dbua : Now runs the upgrade scripts in parallel mode. Speeding up the whole process.
  • smart flash : Can use SSD’s as extention of Buffer Cache.
  • RMAN : can now do recover table
  • RMAN : Standby databases can now use RMAN to apply an incremental backup automatically ( Recover database from for standby )
  • RMAN : Now automatically converts datafiles from 1 platform to the other. ( big-little endian )
  • dbconsole is renamed to “EM Express” and now runs from inside the database.
  • Many more new features but I concentrated on virtualization and linux during OOW while my colleague did 12c.

OVM 3.2.1 in public beta

  • Support for mySQL databases as repository for the OVM Manager
  • OVM Manager now supports OVM on SPARC
  • Statistics of OVM Servers now available in OVM Manager ( Health tab)
  • Minor GUI changes and fixes
  • UEK2 kernel in dom0 for driver compatibility with Oracle Linux
  • OVM CLI now integrated and further enhanced
  • next Beta refresh will contain open Vswitch
  • OVM is now integrated in ODA and Exalogic, but each node has a local OVM cluster. No HA.

Oracle Linux

  • ksplice : allows for kernel upgrades without downtime
  • yum security updates : Now possible to apply only security updates to your system using yum
  • Dtrace : Solaris utility that was ported to Oracle Linux.
  • BTRFS : ZFS-like filesystem for Linux.
  • UEK3 is coming
  • SELinux profiles for every oracle product will be provided in the future
  • Linux Containers : Allows for isolation of applications while maintaining 1 OS.
  • support for swapfile over NFS
  • cgroups : Allows for limiting CPU,IO and memory on process level.

Acquisition of Xsigo was announced

  • Allows for virtualizing of network layer.
  • Will be integrated in OVM Manager in future releases.
