Oracle 9i Depends on Oracle 10g (6229179)

You might see the following message when importing the Oracle 9i plug-in:

Unable to install plug-in "com.sun.oracle9i_DB" version 1.0. This plug-in has a dependency 
on another plug-in "com.sun.oracle10g_DB" version 1.0, which was not found. You may need to 
install the missing plug-in first before re-trying to install this plug-in. (604010)

Workaround: Import the Oracle 10g database plug-in first. Both Oracle database plug-ins depend on the common OraSpt component. This component is part of the Oracle 10g plug-in, therefore you must import the 10g database plug-in first.
