Newbie: Architecture question
I am looking at using Turbine as the framework for my application. We
already have designed a database schema for the application which
incorporates user authentication data, etc. We have the concept of an
individualID which is a primary key on the core user table (individuals)
and a foreign key on several related tables (addresses, logins,
individual_type), etc. Now I come to look at Turbine I see it has its
own user-auth mechanism.
Will it be easy for me to integrate these or should I build my own auth
mechanism into the Turbine framework from scratch? Sorry if this sounds
a simple question - I'm just getting into Turbine. Any advice you can
give would be much appreciated.
Best,
M

DB Pooling and Processes
Posted by Bob Swerdlow <rs...@transpose.com>.
Hi, y'all -
Is there documentation somewhere about how to set up Oracle with Turbine DB
Pooling?
We ran into a problem recently where we were getting "cannot get connection"
errors. I found that our TurbineProperties.Resources had:
# The number of database connections to cache per ConnectionPool
# instance (specified per database).
database.default.maxConnections=3
Since the failure happend when our code was setting up 4 connections, I knew
I had to change this. After a bit of web-snooping, I changed it to 100.
Now we are getting this error:
ORA-00020: maximum number of processes (50) exceeded
This actually happened after reloading the project a few times.
So my questions are:
1. What is an appropriate value for database.default.maxConnections? This
will be a public web site with many concurrent users retrieving pages that
will access the database
2. Do I need to coordinate the number of connections with the number of
Oracle processes? How do I control this in Oracle?
3. Should reloading the project release all of the connections? It does
not seem to have done so, however, when I restarted Tomcat, those processes
seemed to go away.
4. What else should I worry about?
Thanks for your help!
