Atomikos

[308311382]

Atomikos分两个：一个是开源的TransactionEssentials，一个是商业的ExtremeTransactions。
TransactionEssentials的主要特征：JTA/XA 事务管理 —— 提供事务管理和连接池不需要应用服务器 —— TransactionEssentials可以在任何Java EE应用服务器中运行，也就是不依赖于任何应用服务器开源 —— TransactionEssentials是遵守Apache版本2许可的开源软件专注于JDBC/JMS —— 支持所有XA资源，但是资源池和消息监听是专供JDBC和JMS的与Spring 和 Hibernate 集成 —— 提供了描述如何与Spring和Hibernate集成的文档
一、环境

spring 2

ibatis2

AtomikosTransactionsEssentials-3.7.0 下载地址：http://www.atomikos.com/Main/InstallingTransactionsEssentials

MySQL-5.1 ：数据库引擎为InnoDB，只有这样才能支持事务

JDK1.6

Oracle10


二 jar包

Atomikos jar必须包 transactions-jdbc.jar

transactions-jta.jar

transactions.jar

atomikos-util.jar

transactions-api.jar

ibatis,spring

只要符合二者集成jar组合即可，无额外jar

三、配置

Oracle用户授权：（视情况而定，如果程序出现如下异常则需要加上1672 [main] WARN atomikos - ERROR IN RECOVERY com.atomikos.datasource.ResourceException: Error in recovery）

grant select on sys.dba_pending_transactions to orcl;

grant select on sys.pending_trans$ to orcl;

grant select on sys.dba_2pc_pending to orcl;

grant execute on sys.dbms_system to orcl;


jta.properties 配置文件，即src/ jta.properties内容如下：

com.atomikos.icatch.service=com.atomikos.icatch.standalone.UserTransactionServiceFactory

com.atomikos.icatch.console_file_name = tm.out

com.atomikos.icatch.log_base_name = tmlog

com.atomikos.icatch.tm_unique_name = com.atomikos.spring.jdbc.tm

com.atomikos.icatch.console_log_level = INFO
