分析可能是什么问题,

Answer 1

呵呵，像是一个老用户的环境。
如果是突然实现大面积Oracle备份有问题，问题会出在server上，不会是client上。弄不好就是解析的问题。

Answer 2

无牙维护过？还是在等待解决的方法论

Answer 3

你最好在oracle机器上将NBU的bphdb,bpcd的日志激活，看一下具体的信息，你提供的信息太少了，没有办法差。
这个主机名称看着有点眼熟牙，呵呵。

Answer 4

以上信息都是MMSERVER的

Answer 5

MMSERVER

[p590c3b:root:/usr/openv/volmgr] more vm.conf
MM_SERVER_NAME = p590c3b
REQUIRED_INTERFACE =p590c3b
DEVICE_HOST =p590c3b

MASTER

  /usr/openv/netbackup/bp.conf里已经有本条信息

SERVER = gznbumaster
SERVER =p590c3b
CLIENT_NAME = p590c3b
EMMSERVER = gznbumaster
REQUIRED_INTERFACE = p590c3b
MEDIA_SERVER=p590c3b

Answer 6

这个错一般出在hostname的解析上，你用bpclntcmd 在master server检查一下。
顺便把client和server的bp.conf贴上来看看

Answer 7

没有问题

Answer 8

普通文件的备份能成功吗？

Answer 9

无牙兄,帮忙回复呀
