各位大大们啊！ 请支持一下啊！

此问题难呀.........
最好是找SUN的工程师问吓.............他们在此方面比较强...........

这个是linux下的脚本问题啊！

搂住能不能把配置的全过程写个文档给大家共享一下呀？？？
谢谢了

楼主别幼稚，你跑生产环境嘛？ORACLE没技术支持嘛（盗版）？自己玩玩还可以，像你这样什么不懂如果直接跑生产环境的话将来出问题你要死人的。

请问以上脚本有成功了的吗?尤其是监控功能.
我现在是生产环境,但是监控功能没有.
不敢轻易尝试.如果有那位大哥用以上脚本成功了的,麻烦共享一下成果
谢谢!

还有就是,这个脚本,oracle或者linux的官方不会给你,或者提供技术支持.
我的oracle和linux都是正版,打两家的技术支持都说由于涉及其他公司产品,不会提供双机环境下的脚本,一般都是集成商自己编写的.

我觉得启动和停止oracle的脚本倒好解决,最主要是监控oracle状态的脚本不好搞.
看到以上的那些脚本,我很高兴,但是由于没有测试环境,所以不敢轻易的换到生产环境中去.

我现在脚本手工启动没有问题了， 但是加入cluster中后， cluster启动脚本有问题， 不能启动这个脚本的服务，所以我想知道如何让cluster中， 自动的加入参数start、stop启动

你的可rhcs可以启动脚本的是如何设置的？ 还是rhcs 自动的会加入参数 start 、stop 让脚本启动啊？

现在发现的问题是， 似乎是cluster根本，没有启动我的脚本， 我脚本如果得到start 、stop 都会产生log
