----------------------------------------
The FAQ link refers to the JBoss Cache optimistic/pessimistic locking difference, which is
different to Infinispan's optimistic/pessimistic stuff we've added. We're
working on fixing that FAQ to be more clear. Please read
http://infinispan.blogspot.com/2011/10/transaction-remake-in-infinispan-5... to
understand what the new optimistic/pessimistic locking stuff means for Infinispan.
Finally, I don't think AS7 based Infinispan caches have their transactionMode
configurable yet, so you cannot change that yet. The best is probably to deploy your own
cache manager with your own configuration instead of relying on AS7's Infinispan cache
config here so that you can configure pessimistic transactionMode.
Ability to test and acquire lock if available, without aborting the
txn if not available

Key: ISPN-1556
URL:
https://issues.jboss.org/browse/ISPN-1556
Project: Infinispan
Issue Type: Feature Request
Affects Versions: 5.1.0.BETA2
Environment: AS7.1.0.alpha2
Reporter: Gary Brown
Assignee: Galder Zamarreño
I have a system that performs a large number of tasks in a single transaction for
efficiency. Some of those tasks access infinispan caches.
I found that occasionally I have been getting lock timeouts for the default 15 second
period.
Lock contention is not a problem - but the impact of failing to obtain the lock results
in the whole transaction being aborted, which aborts the work also carried out for
potentially a large number of other tasks, resulting in all of the work being retried.
I was wondering if it would be possible to provide an alternative lock implementation the
AdvancedCache that allowed a client app to test whether the lock was available and acquire
it - returning 'true', but if the lock was not available, simply returning false,
allowing the client code to make a decision about how to proceed.
In my case, I could then add the specific task to a retry queue, and move onto the next
task, committing all of the work that had been successfully completed for the other tasks.
