Modify the default Oracle WebLogic Server configuration files

Perform these steps using the non-privileged user account on the application server.

1. Navigate to the Oracle WebLogic Server domain bin directory, for example:
   $ cd /u01/app/oracle/product/Middleware12c/user_projects/domains/empirica/bin
2. Edit the setDomainEnv.sh file:
   1. Using a text editor, open the setDomainEnv.sh file.
   2. At the end of the file, add the following lines:

      # Local Customization
      export TZ=UTC
      export LANG=en_US.UTF-8
      export DISPLAY=:99.0

   3. Save and close the file.
3. Make the edits below in setStartupEnv.sh:
   1. Using a text editor, open the file.
   2. Search for lines containing the following text:

      com.oracle.db.jdbc7-dms.jar

   3. Use the hash character (#) to comment out each line, and then replace each line as follows:

      if [ "${PRE_CLASSPATH}" != "" ] ; then
         #PRE_CLASSPATH="${PRE_CLASSPATH}${CLASSPATHSEP}${COMMON_COMPONENTS_HOME}/modules/features/com.oracle.db.jdbc7-dms.jar"
        PRE_CLASSPATH="${PRE_CLASSPATH}${CLASSPATHSEP}${ORACLE_HOME}/jdbc/lib/ojdbc8.jar"
        export PRE_CLASSPATH
      else
        #PRE_CLASSPATH="${COMMON_COMPONENTS_HOME}/modules/features/com.oracle.db.jdbc7-dms.jar"
        PRE_CLASSPATH="${ORACLE_HOME}/jdbc/lib/ojdbc8.jar"
        export PRE_CLASSPATH
      fi

   4. Search for lines containing the following text:

      java.awt.headless=true

   5. Use the hash character (#) to comment out each line, and then replace each line with a copy of the original, but without -Djava.awt.headless=true. For example:

      # EXTRA_JAVA_PROPERTIES="${EXTRA_JAVA_PROPERTIES} -
      Dem.oracle.home=/u01/app/oracle/product/Middleware12c/em -
      -DINSTANCE_HOME=/scratch/u01/app/oracle/product/Middleware12c/user_projects/domains/empirica -Djava.awt.headless=true -
      Doracle.sysman.util.logging.mode=dual_mode"
      EXTRA_JAVA_PROPERTIES="${EXTRA_JAVA_PROPERTIES} -
      Dem.oracle.home=/u01/app/oracle/product/Middleware12c/em -
      DINSTANCE_HOME=/u01/app/oracle/product/Middleware12c/user_projects/domains/empirica -
      
      Doracle.sysman.util.logging.mode=dual_mode"

   6. Save and close the file.
