Upgrading to Oracle 12c

  • If using Java 7, use the ojdbc7.jar

  • If using Java 6, use the ojdbc6.jar

    • Both downloadable from Oracle (Search for 12c Drivers).

  • Use the org.hibernate.dialect.Oracle10gDialect in all applications

  • Update the actionservice hibernate properties to actionservice.hibernateProperties=actionservice.defaultProperties

  • Update your oracle/network/admin/slqnet.ora File

    • SQLNET.ALLOWED_LOGON_VERSION=8

      • In 12.1, the default value for the SQLNET.ALLOWED_LOGON_VERSION parameter has been updated to 11. This means that database clients using pre-11g JDBC thin drivers cannot authenticate to 12.1 database servers unless the SQLNET.ALLOWED_LOGON_VERSION parameter is set to the old default of 8.

    • Note that the SQLNET.ALLOWED_LOGON_VERSION parameter has been deprecated in 12c. The parameter has been replaced with:

SQLNET.ALLOWED_LOGON_VERSION_SERVER
