java.sql.SQLException: Internal - Unexpected value

Home | Profile 

Below is an error that we got while trying to run a JDBC Java  Program from a Mainframe zOS client against Oracle 11g Database. SR was logged and finally oracle concluded it as a bug - 12851493 (Refer Metalink/Oracle Support site for more details). While hunting for some leads about this error, couldn't find any helpful sites, so thought to post it here and I hope it will be of help to someone.

Workaround ( Suggested by Oracle Support)

Is to use the file.encoding=UTF-8 in the JVM startup or the program itself.

java -Dfile.encoding=UTF-8 TestJDBC

  1. Thanks You help me a lot

  2. I just had the same issue and your solution (-Dfile.encoding=UTF-8) works. I see the bug on the Oracle support site. Any idea on if they plan to actually fix it?

  3. Thanks for posting this. I went to Oracle and found the issue immediately. In my situation, I used the old ojdbc14.jar successfully.

  4. I just downloaded the Oracle 12c release of ojdbc6.jar from here: http://www.oracle.com/technetwork/database/features/jdbc/jdbc-drivers-12c-download-1958347.html

    Now, instead of this:
    java.sql.SQLException: Internal - Unexpected value
    I get this!
    java.sql.SQLRecoverableException: IO Error: Undefined Error

    Oy! :-(

  5. The "java -Dfile.encoding=UTF-8 ... " solution worked for JDK 1.7 connecting to Oracle 11g express edition. Thanks much!
