【IT168 资讯】林子大了，什么鸟都有；江湖时间长了，什么事情都会遇见；不管愿意也好，不愿意也好，很多事情总是那么没有任何征兆没有任何理由地出现；就像美好的爱情的出现也仿佛一个交通追尾的发生一样。

　　有天，用户跟我说，他们的tsm无法工作，仔细一查居然是日志卷慢了，也难怪，用户的备份全是海量的小文件，自然需要消耗日志的空间，我们可以用下面的方式去不用启动tsm server，就可以发布命令来达到一些目的。

　　1、看下目前的logvollume的情况
C:\Program Files\Tivoli\TSM\server>dsmserv display logvolumes

　　2、C:\Program Files\Tivoli\TSM\console>dsmfmt -log d:\log.dsm 100

　　物理上面为log增加一个log卷

　　3、C:\Program Files\Tivoli\TSM\server>dsmserv extend log d:\log.dsm 90

　　这是在逻辑上面将log vollume给扩充了，这样，才是空间才是真正的扩充了。

　　这样就可以了

　　4、现在可以再看下目前的logvollume的情况

C:\Program Files\Tivoli\TSM\server>dsmserv display logvolumes

　　这样我们就可以看见，日志满的问题解决了，tsm server进程也可以正常启动了。

　　同时我们也可以看见，tsm里面就是有个小的数据库，而且因此，tsm的日志模式也可以设置为归档和循环。Tsm里面的数据卷就相当于oracle的数据文件相当于db2里面的表空间，tsmserver的各种配置和参数的表就在其中。

　　数据库的应用简直无处不在！网游，Qq，Websphere，Ldap，monitor，等等。真是有屎的地方就有屎壳郎，有数据的地方就有数据库，当然特别的应用和特别的特点可能会催生不同偏向的数据库，据说现在taobao就在动手自己的数据库，盛大也要开始搞特别适合自己的数据库的产品，我是说数据库软件。什么云计算就是天上的白云，也像恋人的谎言，美丽看不到现实。

　　软件都很简单，见怪不怪了。怪的就是没有什么征兆地出现各种奇异的问题。不可捉摸和不可掌握本身就是大多数人的特别是管理人员的心头大患，希望软件质量更好，希望大家本领更强。
