2. Installations:

WebSphere 6.0.2 Clustering Installation

a. Install WAS6.0.2 Application server on 2 Different machines.b. Install WASv6.0.2 Network Deployment Manager on one machine. Create a profile DMGR

using profile creator.c. Install IBM HTTP Server v2.0.47 on the same machine where WASNDM is installed.d. Install IBM HTTP Server Plug-in on the same machine where WASNDM is installed.e. Install connectJDBC driver for SQL Server. You can download latest connectJDBC driver

from www.datadirect.com site.

Steps to Configure NDM 1. Create Profile DMGR using profile Creator if not created while installation.

2. Start NDM by giving following command…<NDM Install Folder>\profile\DMGR\bin startManager

3. After successful start of NDM go to<NDM Install Folder>\profile\DMGR \logs\SystemOut.logRead for “SOAP Connector Port” [Default Port: 8879].

4. On Node machines where WAS6.0.2 is installed. [On both machines with WAS6.0.2 setup] and execute the batch file addNode as explained below…<WAS6.0.2 Installation Directory>\profiles\default\bin addNode <NDM Machine Name> 8879

e.g. addNode PUNITP64411D 8879Here on PUNITP64411D system WAS-NDM is installed.

8. After adding Servers Nodes to Cluster, stop ManagerStopManager

9. Now Start the Node from the respective WAS6.0.2 servers<WAS HOME>\bin\startNode

10. Install EAR or WAR as per the WAS6.0.2 Installation Documents. If you directly installing application WAR or EAR through NDM Admin console then map the modules to cluster directly rather than mapping the modules to individual servers.

Setting plug-in for NDM

Following steps needs to be followed for any type of HTTP Server. E.g. IIS, IBM HTTP

Server, Apache Web Server etc.

1. Install application WAR or EAR on NDM.

2. While installing select Cluster Name while doing server mapping for modules of Application WAR or

EAR.

3. Complete the installation of application as per application installation document.

4. Then Open Command Prompt…

5. Execute the GenPluginCfg.bat batch file from the <WAS-NDM HOME>\bin folder without giving

any parameters…

6. Copy the Plug-in file from <WAS-NDM-HOME>/profiles/Dmgr\config\cells folder.

7. Paste the same file in WAS a v6.0.2 node (both systems where WAS v6.0.2 is installed)in the

following folder path…

<WAS-HOME>/profiles/default/config/cells

8. Open all the Plugin-cfg.xml file and change the path <WAS-NDM-HOME> to <WAS-HOME> of

the respective machines

Apache HTTP Web Server v 2.0.47 Plug-in configuration

1. Install the Apache Web Server (HTTP Serve v2.0.47) on Machine where NDM is installed

2. Install Web Server Plug-in for HTTP Server v2.0 on Machine where NDM is installed.

While installing this it will ask for the HTTP Server installation folder. So install HTTP

Server first then install the plug-in for that HTTP Server.

3. Start HTTP Server.

Copy the Plug-in file from WAS-NDM-HOME>/profiles/Dmgr\config\cells and paste the same in

following folder…<HTTP PLUGIN INSTALL FOLDER>\config\cells

4. Open the entire Plugin-cfg.xml file and change the path <WAS-NDM-HOME> to <WAS-

PLUGIN-HOME> of the respective machines.

5. Restart the NDM as well as HTTP Server.

Microsoft IIS Plug-in Configuration

1. Install the Microsoft IIS v5.0 on Machine where NDM is installed

2. Install Web Server Plug-in for Microsoft IIS on Machine where NDM is installed.

3. Copy the Plug-in file from WAS-NDM-HOME>/profiles/Dmgr\config\cells and paste the same in

following folder…<IIS PLUGIN INSTALL FOLDER>\config\cells

4. Open the entire Plugin-cfg.xml file and change the path <WAS-NDM-HOME> to <IIS-PLUGIN-

HOME> of the respective machines.

5. Open Command Prompt and execute the following command.

configureIIS -install <plug-in file> <virtual directory> <washome> <description>

It will create the Virtual folder for WAS.

e.g. –

IIS Plug-in Home D:\WASIISPlugin

D:\WASIISPlugin\bin> configureIIS -install iisWASPlugin_http.dll IISWASNDM D:\

WASIISPlugin\bin VirtualFolderforWAS

6. Restart the IIS using IISRESET command from command prompt
