Glorp: how to reconnect after image shutdown / load?

Hello!

ZnServers have its own register mechanism by which they listen when they
are tagged as such after image save and load.

I wonder if there is some way to connect to database in Glorp and then
"keep the connection" between image save/load. Or how is this managed
notmally in apps that use databases? Is image "preconfigured" with live
self-healing connection or does some special piece of startup code be
installed so it runs after deployment and image start?

Thanks, Herby

Herby,

I am not aware of any automatic reconnect tools. Kepping a DB connection
alive after an image is closed is surely not desired and chances are the
DB will close the inactive session eventually anyways.

So it's probably best to make the DB connections reconnect on demand.
That means that whenever you open a session, check if a DB connection is
available or establish a new one otherwise.

There are many scenarios that can lead to the los of a DB connection
that you usually cannot influence (network connection drops, DB server
has some error condition etc.) , so this is a good idea anyways.
