Supported Oracle Versions for RDB

  • The following client versions are supported: Oracle Client or higher up to version 19c
  • The following server versions are supported: Oracle Server or higher up to version 19c
  • An excerpt of the server/client combinations supported by Oracle can be found in the table below.
  • Following combinations are officially tested with WinCC OA:
    • Oracle Server with Oracle Client
    • Oracle Server 19c with Oracle Client 19c
  • Only the Standard and Enterprise Editions are supported.
  • Only 64bit versions of the Oracle client are supported.
  • Following additional steps must be taken into account when using Oracle Client 19c:
    • For Linux the following symbolic link must be created: "ln -s libclntsh.so.12.1 libclntsh.so.19.1"
    • The config entry "[rdb] oracleClientVersion = 19" must be set within the config file of your project.
  • Using Oracle 19 Client and ODBC the CtrlAdo dbEof() function does not work for cursortypes 1 (adOpenKeyset) and 3 (adOpenStatic) under Windows. This is due to changes outside of the scope of WinCC OA.
  • The VC14 support is automatically installed together with the Oracle client software under Windows!

  • The directory of the Oracle client oci\lib\msvc\vc14 must exist and the OS system path variable must also refer to the directory of the oraocci14.dll in the \oci\lib\msvc\vc14:
    Therefore, the OS system path variable must be extended with the full path of the %ORACLE_HOME%\oci\lib\msvc\vc14 directory at the beginning of the system path.
    For instance D:\app\client\product\\client_1\oci\lib\msvc\vc14;<rest-of-system-path>

  • It has to be considered, that the usage of the Oracle Client is only supported for operating systems officially supported by Oracle. If a different operating system is used and an Oracle Service-Request is required, the problem must be reproducible on an officially supported operating system.
