Configuring the WebSphere node agent to run as a Windows service

1. Change to the \bin directory where WebSphere is installed, for example:

      C:\Program Files\IBM\WebSphere\AppServer\bin

2. Run the following command:

     wasservice -add ctgNode01_nodeagent 
       -servername nodeagent 
       -profilePath "...\IBM\WebSphere\AppServer\profiles\ctgAppSrv01" 
       -wasHome "...\IBM\WebSphere\AppServer" 
       -logFile "...\IBM\WebSphere\AppServer\profiles\ctgAppSrv01\logs\nodeagent\startNode.log" 
       -logRoot "...\IBM\WebSphere\AppServer\ctgAppSrv01\logs\nodeagent" 
       -restart true 
       -startType automatic

3. Use a registry editor, such as Regedit, and open this key:

     HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IBMWAS61Service - ctgCellManager01

4. Create a Multi-String Value named DependOnService.
5. Enter the value "IBMWAS61Service - ctgNode01_nodeagent" for this new key. This will make the WAS Cell Manager service dependant on the node agent service starting first.
