Using Oracle Database 12c JDBC

  1. Check the JDBC Help Pages.

  2. Apply for a UND Engineering Linux Account.

  3. Log in to the Linux Server undcemcs02.und.edu .

  4. Modify the .profile File.
    5.  .profile is the shell startup file and gets executed whenever you log in to undcemcs02. It is located in a user’s home directory and tilde slash (~/) is the beginning of a path to a file or directory below the user’s home directory. To use Oracle JDBC, you need to set environment variables in ~/.profile file by including the following commands:

    ~/.profile 
    # To set up the Oracle environment for your shell account
CLASSPATH=.:/usr/lib/oracle/12.1/client64
CLASSPATH=$CLASSPATH:/usr/lib/oracle/12.1/client64/lib/ojdbc7.jar
CLASSPATH=$CLASSPATH:/usr/lib/oracle/12.1/client64/lib/ottclasses.zip
export CLASSPATH

# To set up the Oracle environment for SQL*Plus
export ORACLE_HOME=/usr/lib/oracle/12.2/client64
export LD_LIBRARY_PATH=${ORACLE_HOME}/lib
export PATH=${ORACLE_HOME}/bin:$PATH
export CLASSPATH

    Enter the following command after updating the .profile file: 
      undcemcs02> source ~/.profile 
  5. Create a JDBC Program.
    6.  For example, create a program named MyJDBC.java . Two sample JDBC programs can be found from EnterCustomer.java and ListCustomers.java.

  6. Compile and Run the Program.
    7.  Assume the Java compiler creates a class MyJDBC.class, 
      undcemcs02> /usr/bin/javac MyJDBC.java 
  undcemcs02> /usr/bin/java  MyJDBC
    where the Java compiler and interpreter are located at 
      undcemcs02>    

      undcemcs02>    

      undcemcs02>
