一、安裝snmp
1、安裝snmp
1.1、獲得安裝的rpm包，注意依賴
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.4 (Tikanga)# yum list all | grep net-snmp*
This system is not registered with RHN.
RHN support will be disabled.
net-snmp-libs.x86_64 1:5.3.2.2-7.el5 installed
如何確定主備？
查看tnsnames.ora連接字符串的ip是什麼，然後ifconfig eth0查看ip
