Hi Benjamin,
The WS-AT specification states nothing about isolation levels. It says
that a transaction defined in WS-AT has ACID properties and consequently
preserves isolation.
Yes, exactly. I guess the specification authors did not want to be too
specific to keep WS-AT open to different applications.
Not every resource is a database ;-)
Is it possible to choose a certain isolation level (1,2,4,8) in Kandula?
Which level is supported by default? (Read uncommitted, read committed,
repeatable read, serializable)
Since WS-AtomicTransaction does not allow transaction level requirements
to be transmitted to the participants/resources, this is something the
application has to take care of.
Of course, it would also be possible to specify an extension to WS-AT
that would allow setting the isolation level when creating the
transaction context.
