Download Description
When using wsinstance command to create IBM® WebSphere® Application Server instances and subsequently to create new application servers for those instances, conflicting port numbers get generated. The problem has been reported internally with two defects which will go into Fix Pack 3 for version 5.0.

This problem applies to WebSphere Application Server 5.0.2 Base and Network Deployment on all platforms.

SCENARIO:
1. Using wsinstance, create an instance of a WebSphere Application Server Base install using a unique startingPort value (say 12400) and call it wasIB1.
2. Start server1 of instance wasIB1.
3. Using wsadmin, connect to server1 of instance wasIB1 and create another application server and call it server2.
4. From the command line (you cannot use wsadmin to do this) start server2.
5. Using wsinstance, create an instance of a WebSphere Application Server Base install using a unique startingPort value (say 12500) and call it wasIB2.
6. Start server1 of instance wasIB2.
7. Using wsadmin, connect to server1 of instance wasIB2 and create another application server and call it server3.
8. From the command line, attempt to start server3.
9. The start will fail with a message stating that the server is already started.

The problem is that both server2 and server3 are being created with the same port assignments (see the node level serverindex.xml file and the server level server.xml file).


There is not a way using the wsadmin create function ($AdminConfig create Server) to force generation of unique port numbers.

This problem can be resolved if during execution of wsintance, the template's serverindex.xml is updated to reflect the new port number. The current template's serverindex.xml is simply copied to the new instance, resulting in the same port number being used for new servers created for both instances.

USERS AFFECTED: WebSphere Application Server 5.0.2 users who use wsinstance tool to create multiple WebSphere instances.
