I'm trying to figure out the proper way to use the Shared.DC.ZRDB.TM.TM mixin class. According to the documentation, I should derive from that class, redefine my _abort and _finish methods, and then call the _register method whenever it is needed.
... If all goes well, I should see something like:
before: 0 after: 1 _finish
However, if I use ab to do a check, like
ab -c 10 -n 1000 http://server:8080/CacheProduct/registerFromWeb
I can see:
_before: 1 _after: 1
which should never happen. Also, I don't see the required calls to _finish. After some request, the _finish reappers, only to disappear again.
Has anyone any suggestion on this topic?
I use it for connections to an SAP system -- and it works well. There are indeed no needs other than to define '_finish' and '_abort'. Note, however, that TM instances should *NOT* be persistent! Persistent TM instances can behave weird!
My problem was exactly that: I was deriving from SimpleItem and TM, therefore the weirdness. Thanks for your insight on this topic. Regards Marco
