Back to How Do I Connect to…

[Contributed by Zachi Klopman]

For an existing SQL file:

  • Right click on the editor (not on the explorer). Choose «set connection info».
  • You will be asked for a connection profile type and name. Assuming this is the first time, you will need to create on, so click on the [Create…] button.
  • A new dialog will appear – click on «SQL Model-JDBC Connection» and then [Next>].
  • Give your new connection a name (say, «xtz») and an optional description. (You may also choose auto-connect at this stage). Then [Next>].
  • You need to select a driver. Assuming this is the first time, you will need to create one – click on […]. A new dialog «Driver Definitions» will open.
  • Scroll to Informix, choose appropriate version and click [Add…]
  • A new dialog «New Driver Definition» will open. Choose «Informix JDBC Driver» template, give a name, set «Edit New Driver Immediately» and [OK].
  • Point to the location of the ifxjdbc.jar file.
  • In the URL line you must set the host, port, database (important!) and INFORMXISERVER. you may also set a user id, password and database name in the following lines.
  • Click [OK].
  • Now choose the driver you just created and [OK].
  • You will now have the details filled in, and you can change them at will – and always remember to [Test Connection]!.
  • If you get «Ping succeeded!», you are fine, and click [Finish]. You can now hook up to the database and do other useful stuff.

If you get «Ping Failed», look at [details]. Here are some easy problems to fix:

Wrong hostname or port:

java.sql.SQLException: com.informix.asf.IfxASFException: Attempt to
connect to database server (<INFORMIXSERVER>) failed.

Wrong database name (or no connect permission):

java.sql.SQLException: Database not found or no system permission.

Wrong username:

java.sql.SQLException: Incorrect password or user
com.informix.asf.IfxASFRemoteException: [email protected] is not known
on the database server.

As an exercise for the reader, figure out what this error message means:

java.sql.SQLException: User (com.informix.asf.IfxASFRemoteException:
[email protected])'s password is not correct for the database
