| 一、安装oracle软件,
设置系统内核参数等
设置oracle环境变量
[oracle@localhost oradata]$ vi /home/oracle/.bash_profile
export ORACLE_BASE=/opt/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/10.2.1/db_1 export ORACLE_SID=ora10 export ORACLE_TERM=xterm export PATH=$ORACLE_HOME/bin:$PATH:/usr/sbin:$HOME/bin unset USERNAME 二、配置raw存储 AS4u5默认内核支持lvm2裸设备,模块需要动态加载 1.动态加载模块 编辑rc.local文件 [root@localhost ~]# vi /etc/rc.local #!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don''t # want to do the full Sys V style init stuff. touch /var/lock/subsys/local #mount lvm2 module modprobe dm-mod 2.列出加载的模块 [root@localhost ~]# lsmod|grep dm_mod dm_mod 65001 1 dm_mirror 3.fdisk分区 [root@localhost ~]# fdisk /dev/sdb Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won''t be recoverable. The number of cylinders for this disk is set to 1305. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) Command (m for help): help h: unknown command Command action a toggle a bootable flag b edit bsd disklabel
c toggle the dos compatibility flag d delete a partition l list known partition types m print this menu n add a new partition o create a new empty DOS partition table p print the partition table q quit without saving changes s create a new empty Sun disklabel t change a partition''s system id u change display/entry units v verify the partition table w write table to disk and exit x extra functionality (experts only) Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-1305, default 1): Using default value 1 Last cylinder or size or sizeM or sizeK (1-1305, default 1305): Using default value 1305 Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks. 4.显示分区大小 [root@localhost ~]# fdisk -l Disk /dev/sda: 21.4 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 25 200781 83 Linux /dev/sda2 26 286 2096482 82 Linux swap /dev/sda3 287 388 819315 83 Linux /dev/sda4 389 2610 17848215 5 Extended /dev/sda5 389 2610 17848183 |
