IBM Websphere: Change config if machine name or network name changed

March 16, 2010 by Rohit Prabhakar 3 Comments

Recently you changed the machine name or network name and now you are facing problems with the IBM WebSphere. The behavior of the application server has turned weird as it does not stop when asked to stop from the console or the menu etc.

In order to fix this problem we can update the new name wither manually or from admin UI of IBM WebSphere.

MANUAL

  • Open the serverindex.xml in an editor. C:WS6AppServerprofilesdefaultconfigcellsLTL3AHM4MNode01CellnodesLTL3AHM4MNode01serverindex.xml (This path may be different on your machine)
  • Replace all the instances of the old computer name with the new name
  • Save

ADMIN UI

You can also do this from the Admin console of the server.

  • Go to Click Servers > Application servers > server1
  • Select Communication > Ports
  • Over here you will see the old host name in the Host column.
  • Click on every port name and change the host value to the new value.

Click Save when all Host values have been updated.

Personalized Google search becomes more personal

March 4, 2010 by Rohit Prabhakar Leave a Comment

Today Google announced a new feature of STARS to give a better personalized search. This will help us to mark some results as favorite and we can get this on the top of the list whenever we search for the same thing again. It will be fantastic as lot of times I want to go back to the same old link that I goggled, but till now there was no way except bookmarks! Google will start rolling this out in coming days to all its users.

With stars, you can simply click the star marker on any search result or map and the next time you perform a search, that item will appear in a special list right at the top of your results when relevant.

How to Use WAS profiles to create multiple independent user configurations: IBM Websphere

February 26, 2010 by Rohit Prabhakar Leave a Comment

How to Use WAS profiles to create multiple independent user configurations sharing the same install binaries. This is almost like having multiple servers.

Server: IBM Websphere Application Server 6.1

Tool Used: Use the Profile Management Tool

Note: WAS instances in version 5 are Profiles in v 6

In WAS 6 files are divided into 2 parts Product files and User Data. Hence in order to have multiple instances for different purposed we can have separate User Data sets and these are called as profiles in WAS 6.

By doing this you escape the need of installing multiple servers on the same machine and especially in development environment you can easily control which profile to start (saves lot of resources)

The command is in the following directory:

<was_root>/bin/pmt.sh on UNIX/LINUX

<was_root>binpmt.bat for WINDOIWS


Select “Application Server”

Click “Next”


Select “Advanced Profile Creation”


Don’t Deploy Default Application


Provide an appropriate Name and the default location of the profile

Select the option ” Create the server using development template” if you are not deploying this to a production server and for dev purpose else keep this unchecked.


Give a node name or keep it as it is

Change the Host name to the network name of the server if required


Don’t Select “Enable Administrative Security”


Change the port values as required. (Don’t forget to keep a copy of the port number assigned)


Unselect the “Run the application server process as window service” if you want to have a manual control on the server. As I am using this in development environment I don’t want my server to eat all resources on startup.


Skip this screen


Press “Create”


Select “Launch the first steps console” and verify the profile.
