Forum OpenACS Development: Re: Watchdog fails to run if database is broken
I usually run uptime.openacs.org on all my servers to ensure the instance and db are up and running, along with watchdog.
Just point uptime at /SYSTEM/dbtest.tcl
Together, they cover most errors.
However, I can imagine a scenario where only some database access was broken, such that dbtest.tcl continued to work but Watchdog silently failed to run. That would be a Bad Thing.
