Is the operation of an AE system supported by Oracle Instant Client 12.1 together with an Oracle 12.2 database?
and we said …
As recommended in our online documentation the ORACLE-client version must correspond to the ORACLE version in use.
Note: Installing the JDBC driver
Oracle Company recommend to use ‘ojdbc7.jar’ if Oracle Database 12 is in use.
But there is a bug within the ORACLE JDBC driver (OracleParameterMetaDataParser) - see oracle Bug 18590786
This was fixed within the ORACLE JDBC driver for oracle version 12.2 - the JDBC is already available at http://www.oracle.com/technetwork/database/features/jdbc/jdbc-ucp-122-3110062.html
