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.
