    ODBC Driver Error - DataDirect CLOSED 8.0 Oracle Wire Protocol for Informatica - R36

    Rob Schrage New Member



      1) Installed Informatica Cloud Sercure Agent version 59.17 on on-prem Windows Server 2019 version 10.0 with amd64 architecture.  Agent is running and can be accessed from Informatica Cloud.

      2) Created oracle connection in Informatica cloud with a successful test connection.  Oracle version is 12c.

      3) Created a mapping mapping with oracle as a target.  Target was able to find desired table target in oracle schema and select target columns to map to.

      4) When mapping was run, the following error was generated:


      WRITER_1_*_1> WRT_8147 [2021-06-24 15:59:43.343] Writer: Target is database [odbc://dbtype=Oracle;host={host_name};port=1521;database={db_name}], user [{db_user_name}], bulk mode [OFF]

      Troubleshooting Tasks Completed :


      - Verfied connection string information using sqlplus on server where agent is running.  Was able to insert record into target database.

      - Verified that your Oracle_Home\bin is within your path.

      - Verified that the TNSNAMES.ORA resides in the ORACLE_HOME\NETWORK\ADMIN directory.

      - Checked the SQLNET.LOG file in the ORACLE_HOME\NETWORK\LOG directory. No log files present.

      - Restarted the Oracle Server

      - Checked registry key Computer\HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\DataDirect CLOSED 8.0 Oracle Wire Protocol for Informatica - R36

      "Driver" and "Setup" set to C:\Program Files\Informatica Cloud Secure Agent\drivers\odbc\datadirect\r36\dwora28.dll





      1) How do I solve this database error?  Why can I query the schema in my mapping but receive an error when the task runs?

      2) Should the DataDirect CLOSED 8.0 Oracle Wire Protocol for Informatica - R36 show up in the User DSN or System DSN or Driver Tabs in the ODBC Data Administrator windows tool? I am wondering if the installation of the driver silently failed while installing the informatica cloud secure agent.
