### commEnv.sh
### 
### This script is used to set up a common environment for starting WebLogic
### Server, as well as WebLogic development.  
###
### It sets the following variables:
###
###     BEA_HOME            - The home directory of all your BEA installation.
###     WL_HOME             - The root directory of the BEA installation.
###     JAVA_HOME           - Location of the version of Java used to start WebLogic 
###                           Server. See the WebLogic platform support page
###                           for an up-to-date list of supported JVMs on your platform.
###     JAVA_VENDOR         - Vendor of the JVM (i.e. BEA, HP, IBM, Sun, etc.)
###     PATH                - JDK and WebLogic directories will be added to the system path.  
###     WEBLOGIC_CLASSPATH  - Classpath required to start WebLogic Server.
###     LD_LIBRARY_PATH, LIBPATH and SHLIB_PATH    
###                         - Locate native libraries.
###     JAVA_VM             - The java arg specifying the VM to run.  (e.g. -server, -hotspot, etc.)
###     MEM_ARGS            - The variable to override the standard memory arguments passed to java.
###     CLASSPATHSEP        - CLASSPATH delimiter.
###     PATHSEP             - Path delimiter.
###     POINTBASE_HOME      - Point Base home directory.
###     POINTBASE_TOOL      - PointBase tools jar.
###     POINTBASE_CLASSPATH - Classpath needed to start PointBase. 
###     PRODUCTION_MODE     - Indicates if the Server will be started in PRODUCTION_MODE
###
### It exports the following function:
###
###     trapSIGINT     - Get actual PointBase PID when running in MKSNT environment;
###                      trap SIGINT to make sure PointBase will also be stopped.
### 
###     resetFd        - Reset the number of open file descriptors to 1024.
###
### jDriver for Oracle users: 
###    This script assumes that native libraries required
###    for jDriver for Oracle have been installed in the proper location and that 
###    your os specific library path variable (i.e. LD_LIBRARY_PATH/solaris, 
###    SHLIB_PATH/hpux, etc...) has been set appropriately.  Also note that this 
###    script defaults to the oci817_8 version of the shared libraries. If this is 
###    not the version you need, please adjust the library path variable 
###    accordingly.

  JAVA_HOME="/opt/bea/jdk141_02"
