Installation of High Availability DataBase with N1 Service Provisioning System


Please look at my previous blogs on Application Server Plugin and the Provisioning of GlassFish in general to get an overview and details on the Application Server Plugin for N1SPS.

The Application Server Plugin allows you to install High Availability Database (HADB) on a Target host(s), its also required to associate this installation with an existing DAS. User can start and stop the HADB agent, uninstall and uninstall (markOnly) the HADB. It will also allow youto view the list of HADB's installed.

Here we will take a look on how to use the N1SPS Application Server Plugin to Install and Uninstall the HADB.

Installation

Click on 'Infrastructure Tasks' on your left Pane and select 'Install' under 'HADB' on the right Pane. You will see the following screen.

HADB Installation

Now select the 'Target Hosts', the machine(s) where you want to install the HADB. Now you click on 'Edit Variable Set'. You will see a dialog where you need to fill in the values for HADB sourceImage (the location to the downloaded HADB bits), you will also need the domain host name.
Load Balancer Installation VarSet

Once you are done with the above steps, click on 'Run'. This will take a while and you will see the status once the plan is run completely. You are now ready to use the HADB.

Uninstallation

Lets see how to uninstall an existing installation of HADB.

Click on 'Infrastructure Tasks' on your left Pane and select 'Uninstall' under 'HADB' on the right Pane. You will see the following screen. Select the HADB installation that you want ot uninstall. Click 'Run Selected Installation'.

Uninstall Load Balancer Plugin

Click on 'Run' on the next screen, this will uninstall the HADB from the selected hosts.
Load Balancer Plugin Uninstallation
Note\*

Please note that when installing the Application Server with IFR 9.1 installation bits, the N1SPS will install the HADB bits too in the background. So, if you try to install the HADB, and if plugin sees an existing installation of HADB, it will simply do a 'markOnly' installation of HADB implicitly.
This was done to overcome a bug in IFR which doesn't support an incremental install of HADB component over an existing Application Server Installation.

Prashanth,

Is it possible to selectively install the HADB using the IFR9.1 installation bits? That is, choose NOT to install the HADB using the AppServerInstall component? thanks.

Hi Prashanth,

there is currently no plugin for glassfish v2 or sun appserver 9.x.
i heard and it looks like - there is no more development on this plugin. would you mind sending me the plugin as it is rigth now?
I have to do some provisioning tasks in a short future with glassfish.

and after seeing all these blogs it would be a shame to start all over again.

thanks
