Home -> Community -> Usenet -> c.d.o.server -> Re: Context filter problem
Roger,
This is a limitation of the filters that are included with ConText of Oracle7, unfortunately. You are able to create a policy on a column using the auto-recognize filter ("BLASTER" filter) or you can create a policy on a column with an external filter, but not necessarily both.
I don't always mean to come across as "an upgrade will solve all your problems", but if you have the option to upgrade to Oracle8i and interMedia Text, I recommend it (I'm not "upselling"...if you're a supported customer, you should be able to upgrade at no charge).
The filters used with interMedia Text are from Inso, the same company who produces OutsideIn. Very stable, very good, and includes a PDF filter that actually works. Additionally, the API with interMedia Text is much simpler and performance is dramatically improved.
Hope this helps.
