Server fails to start

The following content provides solutions when the server fails to start.


Server fails to start after configuring the data collector for Oracle

The problem: On Windows Server 2003 R2 Enterprise x64 Edition Service Pack 2, after configuring the data collector for Oracle, the server instance fails to start with the following message in the log file:

"Error occurred during initialization of VM Could not reserve enough space for object heap"

The reason: Windows Server 2003 R2 Enterprise x64 Edition Service Pack 2 fails to reserve sufficient object heap for 32-bit JVM process when it tries to load a dynamic-link library before startup.

The solution: Change the maximum JVM heap size to a smaller value. For Oracle application server, this value is specified in opmn.xml by "-mx" or "-Xms" parameter.


WebLogic Portal 8 cannot start server from Windows service

The problem: For WebLogic Portal 8, starting the server as a Windows Service in production mode: cannot start the server from Windows Service after configuring the data collector.

The solution: Find the cache files (on the directory {wldomain}\{wlinstance}\.wlnotdelete\extract) and remove the following directories:


JBoss fails to start

The problem: JBoss fails to start after running the Start_Application_Server command.

The reason: The JBoss run.bat script uses pipe (|) Windows shell commands to grep (findstr) on the Java -version output. This is probably linked to how Windows Shell (and the pipe command in particular) operates when executed on behalf of Windows services.

The solution: Comment out pipe commands in run.bat. However, if a Sun JDK is being used, than commenting out problem commands will cause JBoss to start without the -server option. So the -server option must be added manually, as per the following procedure:

  1. Remove or comment out the following line in the run.bat file.
    %JAVA%" -version 2>&1 | findstr /I hotspot > nul

  2. Add the following line to the run.bat file:
    set JAVA_OPTS=%JAVA_OPTS% -server
