Hi Nathan, I might have a chance to test the Oracle PMDA in the near future, then I can probably do some real hands-on experiments in a realistic environment but one question I already have is related to latencies: the Oracle node is often heavily loaded and sometimes when things don't work perfectly load might be extreme, there might be swapping, and so forth. So requests for Oracle performance stats can take several seconds. How does the Oracle PMDA cope with this so that PMCD won't kill it? Thanks, -- Marko Myllynen |
