That sounds like a race condition for me: problems resulting from interleaving multiple threads executing read or write (at least one) operations on the same data non-atomically when the code is...

Then, if there are no specific requirements for modifications and decisions, that means that you cannot pinpoint smaller parts of your data in which the changes from a specific client thread can be...

Hi Constantine,

yes, it was a bit unclear, under completely cached data-set I mean caching the portions of data required for the decision (parent/children/other relevant attributes) but this is...

I think the most important information has not yet been provided, sorry if I overlooked it:

Will the graph be modified by the traversing code or by other code?
Will individual graph nodes be...

In our performance testing environment in the current project, we will probably use hp rx4640s, which are priced somewhere in the area of 60,000 GBP... I would LOVE to earn that much in a week... :-)...

If you are into rule engines, then you might also try Drools (was it renamed to JBoss Rules?).

Jess is a commercial software, if I remember well, and not even cheap for that.

If you check the sources for StandardXADataSource and co. you will find that all it does is invoke commit() either in XA prepare or XA commit phase. Therefore it is impossible that this can guarantee...

As an independent line of thought, it might be a good approach that the processing of the rules just forward the message to another destination or destinations with information about the relevant...

Hi James,

You might even try an attempt at evaluating all rules with boolean expression trees to see what performance is provided by a naive brute force approach of the expected platform.

The...

Do you need to delete those rows from Table A? If you don't, then you don't need XA at all as you write only to DB B.

If you need to delete and want to use XA, then forget about JOTM+XAPool.
The...

Do you need only the first matching rule, or do you need to find all matching rules or you need to find any matching rule without precedence between the rules?

Will the amount of rules expand...

Hi Jsdc,

the WebFlow has nothing to do with Eclipse. Therefore there is no need for it to be referred by any update site, except that if a plugin wants to put it into a created project, the jars...

Hi Mark,

Just for the record: Postgresql does NOT support XA. It gives you 2PC but that is not yet XA. It is a long way from XA, yet.

Best regards,

Hi Haishan,

Spring's JTATransactionManager class is not a TransactionManager controlling resources directly. It is a PlatformTransactionManager implementation controlling a real JTA...

Hi Derek,

At least M6 is supposed to be a feature/API freeze... although there were changes which affected plugins in 3.0 Release even compared to the last 3.0 RC, that has bitten MyEclipse as far...
