atomikos分布式事務的幾個坑

atomikos幾個坑：
1.jta.properties:
com.atomikos.icatch.output_dir=/datayes/atomikos
com.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 bug
Some 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=false
Also, 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
