Forum OpenACS Development: Using Oracle 10g with OpenACS

Collapse
Posted by Jade Rubick on
We're considering using bug-tracker and forums here at Volunteer Solutions. We're currently on a heavily customized ACS and Oracle 10g.

However, I was having a great deal of difficulty getting the connection to the database to work. I finally tracked down what the issue was.

I applied this patch to the Oracle driver to get it to work with our ACS installation:

/* other tweakable parameters */

This works fine for our ACS installation. However, when I attempted to get OpenACS running on the same laptop, OpenACS wasn't able to connect to Oracle.

After a little bit of poking around, I found that OpenACS assumes that the Oracle driver will call itself Oracle8. So my above patch seems to conflict.

So one approach is to recompile my driver as Oracle8.

The other is to fix OpenACS to be smarter. However, trying that approach has not been fruitful for me:

Changing this, for example, does not actually solve the problem, because earlier:

this is where the list of known database types are. If I change it here, however, it seems that things work. Everything loads up, and I'm able to get partway through the installation.

However, as I feared, the database queries seem to be using only the generic forms of the database queries, never the Oracle ones. So I've confused OpenACS somehow.

Can someone point me in the right direction here?
