PS. I think the code works correctly, but let me know if it doesn't.

Hi Hugi,
I'm not sure if this will work for 4.0 (since earlier you said you are
using it), but this is what I'd use for 3.1:

If you have A->>B, you'd construct a SelectQuery
I’m using Cayenne’s internal mechanism for everything related to the DB and
currently using 4.0.M4-SNAPSHOT. The stack trace we were getting (after
restarting the DB, and the EOF programs had started working) was:
Caused by:
org.apache.cayenne.datasource.UnmanagedPoolingDataSource$ConnectionUna
Hi Hugi,
I don't know the nature of your application. I've used Cayenne's native
connection pooling (stand-alone applications) and JNDI (typically based on
Apache Commons DBCP) in the past. If my memory is correct, Cayenne's
native connection pooling does attempt to do a re-connect on failure.
Hi Michael,
I’m not quite sure, I’m just giving Cayenne my connection information. Should I
be using a different mechanism?
Cheers,

Hi Hugi,
Just out of curiosity, which connection pooling mechanism were you using?
I've seen Cayenne automatically re-connect to PostgreSQL before.

Hi all,
Is there any simple way or me to count the number of destination objects of a
to-many relationship? (without fetching) If not, is there some way to generate
an expression from a relationship, so I can use that expression in my own
counting functions?

Ah, awesome. Added to my config :).

Periodically executes for each pooled connection, and kills connections that
throw during validation. So it ensures that all pooled connections are in a
good state.

Thanks Andrus. I do have “autoReconnect=true” in the string but added the
connectionTimeout, perhaps that helps.
What does validationQuery do?

Probably a DataSource configuration. I am using DB urls like this:
jdbc:mysql://127.0.0.1/db?connectTimeout=0&autoReconnect=true&useUnicode=true&characterEncoding=UTF-8
and also add "validationQuery" parameter to my pool config. Both ensure
reconnects are transparent.

Hi all.
We had some DB problems last night (MariaDB with the ConnectorJ driver). As
soon as I had started the DB back up, our EOF applications were up and running,
but the Cayenne apps were still down and required a restart to start running
again.
Is there any way to tell Cayenne to reconnect t
