Install oralce 11g full version in centos linux
System Environment: CentOS 5.5 64bit Software Version: linux. x64_11gR2_database_1of2 is good. Now you can install: 1. hardware requirement: memory: grep-I memtotal/proc/meminfo officially requires at least 1 GB of memory swap partition grep-I swaptotal/proc/meminfo if your memory is less than 2 GB, the swap partition is 1.5 times the memory. If the memory is between 2 GB and 8 GB, the swap partition should be equal to the memory size. If the memory is greater than 8 GB, swap partition should be 0.75 times the memory. Note: The above swap partition is only the recommended size. In actual installation, it is not mandatory to set the hard disk as df-k enterprise 4.5 GB. If so, the hard disk space should be at least 5 GB at www.2cto.com 2: install the software packages required by the following oracle: binutils compat-libstdc ++ your-libelf elfutils-libelf-devel glibc-common glibc-devel glibc-headers gcc-c ++ libaio-devel libaio libgcc libstdc ++ + make www.2cto.com sysstat unixODBC-devel 3: added support and user groups/usr/sbin/groupadd oinstall/usr/sbin/groupadd dba/usr/sbin/useradd-g oinstall-G dba-s/bin/bash oracle/usr/ bin/passwd oracle set password 4 for oracle users: modify the kernel variable vim/etc/sysctl. conf adds the following content to the final fs. aio-max-nr = 1048576 fs. file-max = 6815744 kernel. shmall = 2097152 kernel. shmmax = 536870912 kernel. shmmni = 4096 www.2cto.com kernel. sem = 250 32000 100 128 net. ipv4.ip _ local_port_range = 9000 65500 net. core. rmem_default = 262144. net. core. rmem_max = 4194304. net. core. wmem_default = 262144. net. core. wmem_max = 1048586/sbin/sysctl-p: modify the system's restrictions on oracle files vim/etc/security/limits. conf oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 six: vim/etc/pam. d/login session required/lib/security/pam_limits.so session required pam_limits.so vim/etc/profile if [$ USER = "oracle"]; then if [$ SHELL = "/bin/ksh"]; then ulimit-p 16384

In the access interface logon box, use the oracle user to log on to www.2cto.com to open the Termial terminal, and run cd/u01/app/database. /runInstaller. The installation interface will be displayed later. You can install the tool according to your specific requirements. Here is a script for automatically enabling and disabling oracle.
