那些遇到过的问题

解决错误:已经与具有多个实例的atomikos一起使用的日志

Mih*_*hir 6 java atomikos

我只在带有atomikos的实时服务器上遇到问题,在我的本地服务器上它完美运行.

我在服务器上的问题是

init()出错:Log已在使用中？

完成异常堆栈跟踪 

java.lang.RuntimeException: Log already in use?

而我从这里搜索常见的解决方案 

Are these instances running in a single machine? .. like, are those running in an app server, where it is pointed to a single CARBON_HOME? .. if so, the "transaction.properties" file have to be removed from /repository/lib and should be put into each WARs classpath location. And each "transaction.properties" file has to be edited to change the log file location. This error comes when more that one instance is trying to access the same transaction log file of Atomikos, or there's also a chance that the earlier JVM shutdown was not done properly and the lock file wasn't released. In that case, you simply have to remove the log file at /repository/data/tmlog.lck file and restart the server.

我遵循这个建议.从tomcat/common/lib中删除属性文件到我的war的classpath.上面相应改变了目录.我也检查tmlog文件,但它在服务器上不存在.

但没有任何作用.仍然会发生错误.

如果你在这里看到atomikos页面

The lock file in question is created to protect the transaction logs against accidental duplicate startups. Otherwise, the logs could get corrupted when two instances of the same transaction manager are recovering on the same data. Normally, it suffices to follow the hints and then delete the lock file manually if needed.

它只是遵循提示,但暗示在哪里？

请帮我解决一下.

atomikos是开源的,

我检查了源代码,发现下面的行是抛出异常

if ( enableRecovery ) {
             //ISSUE 10077: don't complain about lock file if no logging
            try {
                lockfilestream_ = new FileOutputStream ( lockfile_ );
                lock_ = lockfilestream_.getChannel().tryLock();
                lockfile_.deleteOnExit();
            } catch ( OverlappingFileLockException failedToGetLock ) {
                //happens on windows
                lock_ = null;
            } catch ( IOException failedToGetLock ) {
                //happens on windows

我已经在jta.properties com.atomikos.icatch.enable_logging = false中将调试设置为false并重启我的服务器但仍然是同样的错误.

Guy Padron回答后更新

@Guy Pardon感谢您的回答.我知道​​您是AtomIkos的所有者,我经常收到您的邮件.问题是,对于您的免费开源版本,您在代码中硬编码了默认属性,因此如果任何用户绑定从属性文件设置它,则不会覆盖.问题是什么,日志文件是由atomikos在当前目录中通过其默认属性创建的,因此本地环境没有问题,但是无论何时将其上传到共享主机,其中创建文件或目录在服务器的bin文件夹中是不允许,因此上面的错误,所以我调试代码,根据我的需要修改它,并在2012年8月取得成功.当我检查你的代码时,我发现你的代码在我描述的情况下也会抛出错误的异常,并且有很多要点可以改进代码.

谢谢Mihir Parekh

当您部署了多个项目（使用 Atomikos）时，由于写入 atomikos 的日志文件的并发性（错误消息：'Log already in use'）会出现此问题。

要解决此问题，您必须自定义日志文件名，在 atomikos 配置中设置属性 “com.atomikos.icatch.log_base_name” ，如下所示：

<bean id="atomikosUserTransactionService" class="com.atomikos.icatch.config.UserTransactionServiceImp"
      init-method="init" destroy-method="shutdownForce">
    <constructor-arg>
        <props>
            <prop key="com.atomikos.icatch.service">com.atomikos.icatch.standalone.UserTransactionServiceFactory</prop>
            <prop key="com.atomikos.icatch.log_base_name">your_project_name_log</prop>
            <prop key="com.atomikos.icatch.output_dir">../standalone/log/</prop>
            <prop key="com.atomikos.icatch.log_base_dir">../standalone/log/</prop>
        </props>
    </constructor-arg>
</bean>

PS：请注意，我已经更改了属性 ' com.atomikos.icatch.output_dir ' 和 ' com.atomikos.icatch.log_base_dir ' 只是为了保持井井有条，在 JBoss 日志文件的同一目录中创建 atomikos 日志文件。

您确定您的生产服务器上没有任何其他 JVM 可以锁定atomikos 事务日志吗？
