facing performane issue when setup narayana JTA and txbridge out of JBoss ------------------------------------------------------------------------- Key: JBTM-2746 URL: https://issues.jboss.org/browse/JBTM-2746 Project: JBoss Transaction Manager Issue Type: Enhancement Affects Versions: 5.3.4.Final Reporter: Zefa Guan Attachments: ServiceA_logs.zip, ServiceB_logs.zip, ServiceC_logs.zip when setup txbridge under Tomcat8 out of JBoss, I am facing performance issue as below scenario; 1) running 3 tomcat instances 2) A call B via WS 3) B call C via WS 4) when 100 - 200 GET query from " http://localhost:8081/user?action=add " via Service A, all 3 tomcat got stuck for a while then raise exception with attached logs sth similar with quickstart example but no EJB and out of JBoss from https://github.com/jbosstm/quickstart/tree/master/XTS ================================================== WS-AT to JTA (Multi Hop) This example demonstrates a JTA client that invokes a remote EJB over Web services. The JTA transaction is distributed to the remote EJB using WS-AtomicTransaction. The service also acts as a client to a second service. Again using WS-AT to distribute the transaction over Web services. ================================================== {code} servlet client - localhost:8081/user?action=add | -------------------------------------------------------------- ServiceA Tomcat Narayana JTA Webservie - localhost:8082/user?action=add -------------------------------------------------------------- | txbridge | -------------------------------------------------------------- ServiceB Tomcat Narayana JTA Webservie - localhost:8083/user?action=add -------------------------------------------------------------- | txbridge | -------------------------------------------------------------- ServiceB Tomcat Narayana JTA -------------------------------------------------------------- {code} --------------------------------------------- this may caused by race condition/socket timeout/exceed limits, will need to reproduce and research more; at the beginning I thought it was caused by DB resource locking failed but after I commented out all DB access, the problem still there put all my code to https://github.com/JonkeyGuan/txbridgeInTomcat8 for reproducing and reference
