Greetings,
I found the help re fail over very helpful!!!
I've just searched the WLS documentation and haven't found
confirmation of support for timed methods.
Example: obj.method();
- server goes down or hangs
- Some Unix socket level issues may cause the orb giop
protocol
and socket to not detect this scenario for very long
periods
of time. Many minutes to hours to forever
Weblogic Enterprise provides support for timing out a method dispatch
at the Appserver Bulletin Board (BB). If the BB goes down too, I don't
know if the Stub detects this or just hangs. The real bad news is that
when the BB detects too long a method dispatch it throws an exception
back to the client (no transparent re-route and re-dispatch)
It appears WLS has method level fail over, but no timed hung method
detection. WLE has half of the timed method detection and no transparent
fail over or re-dispatch of methods.
WLE has the least useful part of method time out; if the appserver stays up,
but the object hangs or goes down, the client will be notified and there's
no transparent re-dispatch option available. ;-(
Gemstone and Inprise both have method level fail over as does WLS.
Who does both, fail over and timed methods??
LOL <hands up in the air waving about>
:)
I hope some magazine is keeping score here?
Thanks,
curt
