Time out

[nirvanas1979]

hi buddies,

we are running some performance tests on the application which we have developed. we are using Stateless session beans, Jboss 4.x and jdk 1.5. During the performance tests, we are running 8 concurrent threads but are sporadically getting the following error:

2005-08-25 11:54:58,907 WARN [org.jboss.tm.TransactionImpl] Transaction TransactionImpl:XidImpl[FormatId=257, GlobalId=srv-perceptor/36, BranchQual=, localId=36] timed out. status=STATUS_ACTIVE
2005-08-25 11:54:58,907 WARN [org.jboss.tm.TransactionImpl] Transaction TransactionImpl:XidImpl[FormatId=257, GlobalId=srv-perceptor/34, BranchQual=, localId=34] timed out. status=STATUS_ACTIVE

We have restarted the oracle server (our performance db) as I thought the problem is with the database locking but again got this error on running the 8 concurrent threads.

Following attributes have been set for SLSBs:

<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>


<container-transaction>

<ejb-name>StationServiceFacade</ejb-name>
<method-name>*</method-name>

<trans-attribute>Required</trans-attribute>
</container-transaction>

I dont know where to debug this but can you please provide any inputs for the same. I owe a beer to the one who can help me solve this problem (world is so small that you never know when we meet :))

One more thing to add is that it is giving this error while executing a very simple query like following (related to the sequence service):

UPDATE SEQUENCE
SET SEQUENCEVALUE = (SEQUENCEVALUE + ?)
WHERE SEQUENCENAME = ?

Default tx timeout in jboss is 5 minutes. This can be configured in conf/jboss-service.xml under "TransactionManagerService".

I would assume your SLSB does a lot of work and surpasses this 5 minute timeframe. You may have to either increase the tx timeout or split up your transaction.
