Reply: In fact, you do not need 32-bit ocijdbc12.dll file, because your JAVA compiler system is 64-bit, so if you use 32-bit it will result in that JAVA system cannot work properly. I think your JAVA working environment is a problem, and you should carefully check the configuration file.

On Windows platforms:
- Add \jdbc\lib\ojdbc5.jar to
Your CLASSPATH if you use JDK 1.5 or
\jdbc\lib\ojdbc6.jar if you use JDK 1.6.
- Add \jlib\orai18n.jar to your CLASSPATH if needed.
- Add \bin to your PATH if you are using the JDBC OCI
Driver.

On Solaris/Digital Unix:
- Add /jdbc/lib/ojdbc5.jar to your CLASSPATH if you
Use JDK 1.5 or /jdbc/lib/ojdbc6.jar if you use JDK 1.6
- Add /jlib/orai18n.jar to your CLASSPATH if needed.
- Add /jdbc/lib to your LD_LIBRARY_PATH if you use
The JDBC OCI driver.

Ensure that the jdbc OCI DRIVER used by the program is consistent with the oracle client, and that NLS_LANG is consistent with the database and client character set configurations.

After the above configuration, if the program about java.lang.UnsatisfiedLinkError: ocijdbc11...still appears, check whether the JDK version number (32-bit or 64-bit) used by the program is the same as the oracle client version.
