Hi,
I am using Jackrabbit core version 2.2.10 with a MySQL 5.5. database
on Windows 7. I am trying to understand the behaviour of JackRabbit
following a database connection failure. Currently, following a DB
connection failure, Jackrabbit enters into an error recovery mode
which carries on until it eventually manages to reconnect to the
database. If there a way to disable this recovery mechanism or to
control how many times it should attempt to reconnect before giving
up?
I want to be able to "catch" database errors early and report them to
the user, and I don't want Jackrabbit to try to reconnect as this
would be handled somewhere else in my application.
Many thanks,
Guillaume.
PS: here is my xml config file:
