    A timeout occurs while installing more than one OSGi Application
    (EBA) to a liberty server.  The error message will look like the
    following:
    A CWWKZ0403E: A management exception was generated when trying
    to install the application <application-name> into an OSGi
    framework.  The error text from the OSGi framework is: Unable to
    acquire the global write lock in time.
    

Problem conclusion

  • The timeout was hard-coded in the open source Apache Aries
    subsystems implementation.  For large deployments this timeout
    was not long enough.  The solution is to increase the default
    timeout and to provide a way to override the length of the
    timeout in Apache Aries subsystems.  The default timeout can be
    overriden by setting a value for the key
    org.apache.aries.subsystem.lock.timeout in the
    bootstrap.properties.  The value is defined in seconds. For
    example, the following value in the bootstrap.properties file
    sets the timeout to 2 minutes:
    
    org.apache.aries.subsystem.lock.timeout=120
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 16.0.0.4.  Please refer to the Recommended Updates page for
