change jta transaction timeout from default to custom

Question

I am using Atomikos for JTA transaction. I have following setting for JTA:

UserTransactionImp userTransactionImp = new UserTransactionImp();
userTransactionI         


        

Answer 1

From the Atomikos documentation:

com.atomikos.icatch.max_timeout

Specifies the maximum timeout (in milliseconds) that can be allowed for transactions. Defaults to 300000. This means that calls to UserTransaction.setTransactionTimeout() with a value higher than configured here will be max'ed to this value. For 4.x or higher, a value of 0 means no maximum (i.e., unlimited timeouts are allowed).

Indeed, if you take a look at the Atomikos library source code (for both versions 4.0.0M4 and 3.7.0), in the createCC method from class com.atomikos.icatch.imp.TransactionServiceImp you will see:

387:   if ( timeout > maxTimeout_ ) {
388:       timeout = maxTimeout_;
389:       //FIXED 20188
390:       LOGGER.logWarning ( "Attempt to create a transaction with a timeout that exceeds maximum - truncating to: " + maxTimeout_ );
391:   }

So any attempt to specify a longer transaction timeout gets capped to maxTimeout_ which has a default value of 300000 set during initialization if none is specified.

You can set the com.atomikos.icatch.max_timeout as a JVM argument with:

-Dcom.atomikos.icatch.max_timeout=900000

or you could use The Advanced Case recipe specified in the Configuration for Spring Section from the Atomikos documentation.
