Re: [udig-users] problem displaying Oracle layer in udig
|
Hi Alex:
Thanks for the testing (I have added your comments onto http://jira.codehaus.org/browse/UDIG-1584).
Oracle Locator should make some difference (as I understand it a spatial index is not available for oracle locator and all the work is done in Java resulting in very poor performance). Oracle locator is able to store geometry; but not work with them especially well...
It could be the new JDBC-NG datastore no longer supports locator; I will try and check.
What we really need is a developer with access to an oracle machine and time to work on this one.
We are going to try and shortlist issues in Monday's meeting based on volunteer time; we will see how it goes.

I wish I could give you better steps to reproduce the problem, but the behavior of the application seems quite inconsistent and hard to understand. Let me know if I can provide more information which might be helpful.
