atomikos幾個坑：1.jta.PRoperties:com.atomikos.icatch.output_dir=/datayes/atomikoscom.atomikos.icatch.log_base_dir=/datayes/atomikos若一個tomcat上有兩個atomikos應用，則兩個應用不要公用同一位置2.datasource的用戶名密碼url不對，應用啟動會失敗，而且什么錯誤日志也沒有，日志打到中間就沒有新的日志輸出了。3.MySQL XA bugSome users have reported problems with MySQL XA (related to this MySQL bug: http://bugs.mysql.com/bug.php?id=27832external). This problem only happens if you access the same MySQL database more than once in the same transaction. A workaround can be setting the following property in jta.properties:com.atomikos.icatch.serial_jta_transactions=falseAlso, make sure to set the following property on the MySQL datasource:pinGlobalTxToPhysicalConnection="true"MariaDB's java driver also supports this workaround since v.1.1.8
