Multiple nodes created of the same name, but different case
 Technote (FAQ)
 
Problem
WebSphere Application Server will not start.
 
Cause
In WebSphere® Application Server 4.0, you create a new repository, then use the XMLConfig -import command to populate the repository. The XMLConfig file has a node name in a different case than the hostname, such as host1 versus Host1.

After creating the new repository and running XMLConfig -import there are two nodes, host1 and Host1, with the same name, but different case.
 
Solution
Since this problem typically occurs when using XMLConfig to repopulate a new repository from an existing XMLConfig file (created from an XMLConfig -export prior to dropping the original repository), you can use the following process to recreate the configuration with only one node name:
  1. Drop and recreate repository .
  2. Start WebSphere Application Server.
  3. Compare node name in WebSphere (using the WebSphere Application Server Administrative Console) with contents of the XMLConfig file that will be used for import.
  4. Change the node name to match the case listed in the Administrative Console.
  5. Use XMLConfig -import to repopulate repository.

Hints and Tips
  • DB2® commands used to create a repository are listed in the createdb2.scr file in WebSphere's bin directory.
  • When recreating a repository, you must create tables: Edit admin.config to set these lines as follows:
    line.com.ibm.ejs.sm.adminServer.initializeDb=true
    com.ibm.ejs.sm.adminServer.createTables=true
  • Do not recreate the default server automatically because it must be part of the XMLConfig file you are importing: Edit admin.config to set install.initial.config=false.
  • For more details on modifying the node name, see technote:
