Installing Oracle 11gR2 (11.2.0.1) on CentOS6.0 and basic configuration (i)

It's needless to say that you install centos6.0  first. Installation can be done. The only thing to note is that the checking the software requirements part of the Oracle 11G Installation Guide will require a subset of the software to be installed in the CentOS6 DVD image. You can configure a DVD image repos yourself.   Check the command format as follows: Rpm-qa | grep name binutils-2.17.50.0.6            okcompat-libstdc++-33-3.2.3       &NB sp;okelfutils-libelf-0.125            OKELFUTILS-LIBELF-DEVEL-0.125-- elfutils-libelf-devel-static-0.125--gcc-4.1.2                okgcc-c++-4.1.2 & nbsp              okglibc-2.5-24                OKGL ibc-common-2.5            okglibc-devel-2.5                okglibc-headers-2.5            okkernel-headers-2.6.18         &N Bsp  okksh-20060214                oklibaio-0.3.106                oklibaio-devel-0.3.106            --libgcc- 4.1.2                oklibgomp-4.1.2             &NB Sp  oklibstdc++-4.1.2             oklibstdc++-devel-4.1.2         &NBS P  okmake-3.81                oknumactl-devel-0.9.8.i386       & nbsp;--sysstat-7.0.2                --unixodbc-2.2.11                --unixodbc-devel-2.2.11            --  from The Centos-5.5-i386-bin-dvd.iso\centos file finds the missing package and uploads it to Linux,  ls *.RPMRPM-IVH *.rpm centos6.0 Basic Environment Configuration ======== = = = #建立dba和 Oinstall user group.
