Directory conventions

The following directory conventions are used throughout the documentation to must reference special directories such as wxs_install_root and wxs_home. You access these directories during several different scenarios, including during installation and use of command-line tools.

wxs_install_root

The wxs_install_root directory is the root directory where WebSphere eXtreme Scale product files are installed. The wxs_install_root directory can be the directory in which the trial zip file is extracted or the directory in which the WebSphere eXtreme Scale product is installed.

  • Example when extracting the trial:


    Example: /opt/IBM/WebSphere/eXtremeScale

  • Example when WebSphere eXtreme Scale is installed to a stand-alone directory:


    Example: /opt/IBM/eXtremeScale

  • Example when WebSphere eXtreme Scale is integrated with WAS:


    Example: /opt/IBM/WebSphere/AppServer

wxs_home

The wxs_home directory is the root directory of the WebSphere eXtreme Scale product libraries, samples and components. This is the same as the wxs_install_root directory when the trial is extracted. For stand-alone installations, the wxs_home directory is the ObjectGrid sub-directory within the wxs_install_root directory. For installations that are integrated with WAS, this directory is the optionalLibraries/ObjectGrid directory within the wxs_install_root directory.

  • Example when extracting the trial:


    Example: /opt/IBM/WebSphere/eXtremeScale

  • Example when WebSphere eXtreme Scale is installed to a stand-alone directory:


    Example: /opt/IBM/eXtremeScale/ObjectGrid

  • Example when WebSphere eXtreme Scale is integrated with WAS:

    Example: /opt/IBM/WebSphere/AppServer/optionalLibraries/ObjectGrid

was_root

The was_root directory is the root directory of a WAS installation:


Example: /opt/IBM/WebSphere/AppServer

restservice_home

The restservice_home directory is the directory in which the WebSphere eXtreme Scale REST data service libraries and samples are located. This directory is named restservice and is a sub-directory under the wxs_home directory.

  • Example for stand-alone deployments:


    Example: /opt/IBM/WebSphere/eXtremeScale/ObjectGrid/restservice

  • Example for WAS integrated deployments:


    Example: /opt/IBM/WebSphere/AppServer/optionalLibraries/ObjectGrid/restservice

tomcat_root

The tomcat_root is the root directory of the Apache Tomcat installation.


Example: /opt/tomcat5.5

wasce_root

The wasce_root is the root directory of the WAS Community Edition installation.


Example:/opt/IBM/WebSphere/AppServerCE

java_home

The java_home is the root directory of a Java™ Runtime Environment (JRE) installation.


Example:/opt/IBM/WebSphere/eXtremeScale/java

samples_home

The samples_home is the directory in which you extract the sample files that are used for tutorials.


Example:/wxs-samples/
