在用onbar -b -l备份逻辑日志的时候,发生报错,错误信息如下:

2008-09-22 10:17:07 278548  229552 Begin backup logical log 25274.

我是做备份的,对数据库不太熟,请问这个报错是什么原因引起的?数据库肯定是开着的.

数据库重启之后就可正常备份,没有任何问题了,真事匪夷所思,到现在还不知道报错的真正原因....继续等高手指点.谢谢!

onbar就是备份,在onconfig文件里面把tapedev 设成你的磁带设备。还有ltapedev也设成你的磁带设备。然后把onconfig中的onbar相关项目配置好。重起Informix Server，你的逻辑日志就会自动备份到你的磁带设备上了。然后， 你需要备份onbar -b -w， 需要恢复obar -r -p 或者 －l，还有一个很好的功能，onbar -t 时间，可以恢复到任意时间点。
  如果要使用onbar,必须要有存储管理器,这一般是其它厂商的产品,informix和这些厂商都遵守XBSA协议,也就是相应的API接口.否则,只能使用ontape备份了.
另外,informix自己也带了一个简单的存储管理器,你可以参考
Informix Backup and Restore Guide, December 1999这本手册.
