AttributeReqDescriptionPossible values
Basic
The path to the dbload utility.yes

The name of the dbload utility, including the path. The Informix server must be installed and configured on the same machine where CloverDX runs and the user must be logged in as root. The dbload command line tool must be available.

 
Host The host where the database server is located. 
DatabaseyesThe name of the database into which the records should be loaded. 
Database tableyesThe name of the database table into which the records should be loaded.

Details

InformixDataWriter loads data into a database using the Informix database client (dbload utility) or the load2 free library.

It is very important to have the server with the database on the same computer as both the dbload database utility and CloverDX; furthermore, you must be logged in as the root user. The Informix server must be installed and configured on the same machine where CloverDX runs and the user must be logged in as root. The Dbload command line tool must also be available.

InformixDataWriter reads data from the input port or a file. If the input port is not connected to any other component, data must be contained in a file that should be specified in the component.

If you connect a component to the optional output port, rejected records along with information about errors are sent to it.

Another tool is the load2 free library instead of the dbload utility. The load2 free library can be used even if the server is located on a remote computer.

Loader input file

The name of the input file to be loaded, including the path. Normally, this file is a temporary storage for data to be passed to the dbload utility unless named pipe is used instead.

  • If it is not set, a loader file is created in CloverDX or the OS temporary directory. The file is deleted after the load finishes.

  • If it is set, a specified file is created. It is not deleted after data is loaded and it is overwritten on each graph run.

  • If the input port is not connected, this file must exist, must be specified and must contain data that should be loaded into database. It is not deleted or overwritten.
