1: Openfts Initialize Error : Relation 'txt' already exists
Posted by Gilbert Price on 01/22/04 10:01 PM
I've searched the OpenACS site and can't find a clear answer to this one. I've installed OpenACS 5.0.0 final, on a Redhat9 machine with Aolserver 4r2 and Postgresql 7.3.4. I get all the way to initializing the openfts drive and the results are: (I gather the txt table already exisits but I'm not sure who or what put it there first, I'm looking for a way to fix, or integrate openfts use of whatever it needs) 
Database operation "dml" failed (exception ERROR, "ERROR:  Relation 'txt' already exists
")

ERROR:  Relation 'txt' already exists

Any help in correcting this is greatly appreciated. If I was using this installation on the internet I wouldn't bother, but I am behind a firewall where public search engines are not allowed to tread... Thanks,

I vaguely remembered having much the same problem at some point, and looking at my notes for OpenFTS installation I found this statement:

"Also may have to manually drop the txt table if it's been copied in from the template DB [template1], otherwise 'DML failed - relation txt already exists.'"

This is from about 6 months ago, so its not that fresh in my mind, but I think that if you follow the OpenFTS installation instructions and source openfts.sql into your database, it creates the txt table, and so you have to drop it before the driver can initialise properly. I can't offer any guarantee that this is the best possible action, but I seem to remember it working OK.

That's the ticket!

Thanks Tom...
