Oracle Data Miner 4.0.2 adds a number of minor fixes. Below are the fixes relevant to users. These features are supported for all database versions supported by Data Miner (Oracle Database 188.8.131.52 and above).
SQL Developer 4.0.2 corrected an issue on how Oracle NLS client side libraries were managed. The problem in 4.0.1 resulted in Data Miner repository installation failures on databases requiring national language support (NLS) client side libraries to be loaded. This occurred only when the NLS numerical format settings used a comma in place of a decimal. SQL Developer 4.0.2 fixes this problem with Oracle Data Miner installations on databases that required local national language support (NLS) libraries.
Model Build Nodes were failing when a CLOB was passed in as input. This only occurred on 11.2 databases.
JDK Version Validation Applied to Data Miner 4.0.2
There is a minimal version of JDK that is required by SQL Dev. A warning or error is displayed depending on the severity of the version difference. There is, unfortunately, an error in the warning message, that refers the user to an incorrect control file to adjust the JDK that SQL Dev is referencing. Please see the SQL Dev documentation on JDK management to understand the correct procedures and also this posting 4.0.2 doesn't start : Unsupported java version... on the SQL Developer Discussion Forum thread for more information.
