Error description

  • In Liberty Profile v16.0.0.4, if a user manually sets
    Plug-in property ESIEnable to false in the plugin-cfg.xml,
    the changes are overridden with the next plug-in
    regeneration with the default value.
    
    Currently, Liberty does not have the capability for the four
    ESI Plug-in properties to be changed from the following
    defaults:
    
    <Property Name="ESIEnable" Value="true"/>
    <Property Name="ESIMaxCacheSize" Value="1024"/>
    <Property Name="ESIInvalidationMonitor" Value="false"/>
    <Property Name="ESIEnableToPassCookies" Value="false"/>
    
    A fix is required to allow the plug-in properties to be
    changed in Liberty so that the plug-in regeneration will
    persist the changes to the plugin-cfg.xml file.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty - Web Container              *
    ****************************************************************
    * PROBLEM DESCRIPTION: It is not possible to override the      *
    *                      default values for the ESI properties   *
    *                      in the plugin-cfg.xml                   *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The server does not allow you to update the four ESI Plug-in
    properties found in the plugin-cfg.xml.  The following are the
    default values:
    
    Property Name="ESIEnable" Value="true"
    Property Name="ESIMaxCacheSize" Value="1024"
    Property Name="ESIInvalidationMonitor" Value="false"
    Property Name="ESIEnableToPassCookies" Value="false"
    

Problem conclusion

  • The capability to override the default ESI plugin values has
    been added.
    To get the new behavior, please set the properties in the
    pluginConfiguration stanza in server.xml.
    
    For example:
    
    	    <pluginConfiguration ESIEnable="false"/>
    
    Or, multiple properties can be set within the same stanza.  Note
    the below are just example values which differ from the default
    values:
    
    	    <pluginConfiguration ESIEnable="false"
                             ESIMaxCacheSize="500"
                             ESIInvalidationMonitor="true"
                             ESIEnableToPassCookies="true"/>
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.2.  Please refer to the Recommended Updates page for
