Hello,

we're putting the oracle ng to work with udig. It finds the DB all 
right, and almost lists the feature types ok. But I'm running into 
warnings like

WARNING: No primary key or unique index found for MY_TABLE.
10-Sep-2009 10:10:14 org.geotools.jdbc.JDBCDataStore getPrimaryKey
INFO: No primary key found for SOME_OTHER_TABLE

and seeing that udig is blocked.

Are the infos and warnings such as above OK?

One of the tables has around 20 M records. Apparently udig (or 
geotools?)  is taking to long to count something. I've seen it iterating 
over features to calculate a bbox, but this time I'm not sure it's the 
new datastore. Has the oracle ng been tested with large tables? Does 
anyone have a hint where to start looking?

Mind you, I've been told the tables have indices and a basic test class 
(using the oracle ng) lists me my tables without any performance problem.

Thanks in advance!

Ugo
