Thanks – I will check it out. Does this mean that EOF will use
multiple db connections? How do the other connections get used? Is
it based on load? Round robin? Are there any synchronization issues?
I'm pretty sure that it only will if there are multiple EOF stacks or
if you are doing some funky fetches within fetches. With multiple
EOF stacks you will get the same synchronization issues as running
multiple instances.

HI Dov,
JavaERJDBCAdaptor has connection pooling capability. Its based on
code from Lenny Marks and integrated into Wonder. It does -not-
use a tomcat related datasource but the code should help you to
use another pool. Check it out.

Is there any way to convince EOF to use a database connection
pool? I noticed that there appears to be some JNDI lookup for a
datasource but I could not get it to use a Tomcat connection
pool. It looks like there needs to be something set up in the
EOModel but could not come up with the correct combination of
chicken blood and ritual sacrifice to get it to work properly.
My primary motivation is that our apps are deployed as servlets
which makes it harder to run multiple instances of an app in the
same container like JavaMonitor enables when you run as a regular
WO application. The only way we can get multiple db connections
seems to start multiple instances on different machines or run
multiple servlet containers on the same box.
I saw some references to EOF and multiple connection stacks that
looked promising but very complex. Has anyone done this, if so
are there any rules that we should follow.
We have 2 apps. One is a regular WO app deployed as a servlet
the other is a little different. It uses a sharededitingcontext
for performance caching. We may be changing that in the future,
but I am a little concerned with dealing with multiple EOF stacks
while using a SharedEditingContext
