摘要

Microsoft 分布式事务处理协调器服务日志可用性

系统指示可以通过使用组件服务管理工具增加日志缓冲区的数目，解决 Microsoft 分布式事务处理协调器服务 (MSDTC) 的日志文件中存在的问题。

原因

MSDTC 日志缓冲区的数目过少。

解决方案

增加 MSDTC 日志缓冲区的数目

系统指示可以通过使用组件服务管理工具增加日志缓冲区的数目，解决 Microsoft 分布式事务处理协调器服务 (MSDTC) 的日志文件中存在的问题。

管理员

要打开组件服务并增加日志缓冲区的数目，请执行以下操作：

单击“开始”，再单击“运行”。
comexp.msc
依次单击“组件服务”、“计算机”、“我的电脑”、“分布式事务处理协调器”和“本地 DTC”。
右键单击“本地 DTC”，再单击“属性”。
默认最大值是 25。如果增加此上限值，则 MSDTC 会将消息写入事件查看器。此内存取自不可分页的缓冲区。因此，如果不可分页的缓冲区提供的内存量不足，则可能无法为此值设置更高的数字。在这种情况下，MSDTC 将显示警告消息。如果显示警告消息，请单击“确定”。
