[Zope-DB] ZPsycopgDA connection failing

2006-06-07 Thread Davis Mr MR
Hi,

My connection to Postgres keeps failing every couple of hours. I did
read that there was a problem with some versions of this. I'm using
2.0b6 at the moment.

Does anyone have a version number that I can try that will re-establish
a connection on failure.

Cheers
Michael

Hi Charlie,

I was afriad of that. Looks like the firewall is killing it, and it is
not telling the DA.

Will need to speak to our network people.

Thanks for your help.
Cheers
Michael

Michael,

if you look at the DA (db.py) source you will see that it actually tries
to reconnect if no connection is available so the problem must be
somewhere else. PostgreSQL connections themselves don't timeout but if
the database is on a network and the connection is dropped then the DA
may well think it is connected when it isn't. This is difficult to solve
in the DA and you need to know why the connection is being dropped
first.
