Subject Re: Retry connection on broker start when database is unavailable
Date Mon, 24 Jun 2013 17:59:58 GMT
Looked at the code. Looks like the current impl expects the locker to have
achieved the lock at least once. The functionality will then restart the
broker when it loses the lock.

I guess you could implement this blocking/retry-mechanism in your
datasource#getConnection()....So when activemq tries to start up the
persistence adapter it will block there when it tries to aquire a
connection instead of just fail?

If this doesn't suit you, please open a JIRA. we can possibly broaden the
scope of retry mechanisms to include not only keepAlive scenarios.
