Detailed Oracle Installation Process

First of all, you need to understand the requirements for installing Oracle: Red Hat Enterprise Linux AS/ES 3.0 (Update 4 or later) red Hat Linux 4.0 SUSE Linux Enterprise Server 9.0 with SP 2 or laterAsianux 1.0 kernel requirements: The system must be running the following kernel version (or a later version ): red Hat Enterprise Linux 3.0 and Asianux 1.0: 2.4.21-27. ELNote: This is the default kernel version. red Hat Enterprise Linux 4.0 and Asianux 2.0: 2.6.9-5. ELSUSE Linux Enterprise Server 9.0: 2.6.5-7.201 memory requirements: 1 GB disk space requirements: swap space: the disk space in the 1.5 GB/tmp directory is 1.2 MB. For databases with 2.4 GB to GB pre-configured, GB (optional) quick recovery zone is required. For Oracle installation steps: # su-root (log on to the root user) # grep MemTotal/proc/meminfo (view memory, do not be less than 1G) # grep SwapTotal/proc/meminfo (view swap partitions, do not be less than 1.5 GB) # vmstat (Monitor virtual memory usage) if the swap partition is too small, expand the swap partition: # swapoff/dev/sda3 (disable swap partition) # fdisk/dev/sda first deletes the original swap partition, in a large swap partition # mkswap/dev/sda3 (the partition format is swap format) # vim/etc/fstab (set the boot mount) /dev/sda3 swap defaults 0 0 # swapon/dev/sda3 (enable swap partition) # cat/proc/swaps or # free (to view swap partition size) # df-kh/tmp (view the directory where the temporary file is stored, not smaller than 400 M) # grep "model name"/proc/cpuinfo (view CPU type) red Hat Enterprise linux 4.0 requires the following packages:

Then the graphical installation interface is displayed. Just install it as prompted, I think it's easier for everyone! To help you manage oracle Enterperise Manager using three command line tools, use: # emctl start | status | set | stop (which does not support restart) to stop and start SQL * PLus, use: # isqlplusctl start | stop to manage the listener. Use: # isnrctl help | start | status | stop if you want your oracle to support Chinese characters: during installation, select Chinese 500) this. width = 500; "border = 0> of course, your Linux system must also support Chinese!
