3. 3. 验证系统要求(root)

[root@RHEL ~]# grep MemTotal /proc/meminfoMemTotal: 515444 kB（我机器上的，不影响安装，最好是1G之后会报warming）[root@RHEL ~]# grep SwapTotal /proc/meminfo
SwapTotal: 586332 kB （我机器上的,稍后增加swap）

Notes:

查看系统Swap空间使用

[root@localhost ~]# cd /usr/

[root@localhost usr]# free

在空间合适处创建swap文件

[root@localhost usr]# mkdir swap

[root@localhost usr]# cd swap

[root@localhost swap]# dd if=/dev/zero of=swapfile bs=7168 count=70000

70000+0 records in

70000+0 records out

501760000 bytes (502 MB) copied, 6.94737 seconds, 72.2 MB/s

[root@localhost swap]# ls -al

total 490504

drwxr-xr-x 2 root root 4096 Jan 27 04:51 .

drwxr-xr-x 16 root root 4096 Jan 27 04:48 ..

-rw-r--r-- 1 root root 501760000 Jan 27 04:51 swapfile

[root@localhost swap]# grep SwapTotal /proc/meminfo

SwapTotal: 586332 kB

[root@localhost swap]# mkswap swapfile

Setting up swapspace version 1, size = 501755 kB

激活swap文件

[root@localhost swap]# swapon swapfile

[root@localhost swap]# ls -l

total 490488

-rw-r--r-- 1 root root 501760000 Jan 27 04:53 swapfile

[root@localhost swap]# free

[root@localhost swap]# grep SwapTotal /proc/meminfo

SwapTotal: 1076324 kB

所需最小 RAM 为 512MB，而所需最小交换空间为 1GB。对于 RAM 小于或等于 2GB 的系统，交换空间应为 RAM 数量的两倍；对于 RAM 大于 2GB 的系统，交换空间应为 RAM 数量的一到两倍。Oracle 10g 软件还需要 2.5GB 的可用磁盘空间，而数据库则另需 1.2GB 的可用磁盘空间。/tmp 目录至少需要 400MB 的可用空间。要检查系统上的可用磁盘空间，运行以下命令：[root@RHEL ~]# df –h

Notes:

增加 /usr/app/oracle 空间

l 增加 SCSI 硬盘

[root@RHEL ~]# fdisk /dev/sdb

依次打：

n->p->1->回车->回车

l 查看系统磁盘分区信息

[root@RHEL ~]# fdisk /dev/sdb

…

/dev/sdb1 XXXXXXXXXXX

…

l 格式化 /dev/sdb1

[root@RHEL ~]# mkfs.ext3 /dev/sdb1

也可以用

[root@RHEL ~]# mkfs –t ext3 /dev/sdb1

l 创建 /usr/app/oracle

[root@RHEL ~]# mkdir /usr/app/oracle
