In theory, this should not cause any real problem :

Debian Squeeze AMD64安装Oracle 10g x86_64 10.2.0....

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 服务器操作系统为Debian Squeeze AMD64,没有安装X,通过ssh远程访问。客户端为debian testing,安装有gnome桌面环境。 先安装10.2.0.1,然后安装升级包10.2.0.4,比安装10g r2客户端多了一些操作,具体安装过程如下： 一、安装10.2.0.1 1、下载oracle 10g r2 下载回来的文件为10201_database_linux_x86_64.cpio.gz $gunzip 10201_database_linux_x86_64.cpio.gz $cpio -idmv < 10201_database_linux_x86_64.cpio 解压缩后所有的安装文件位于database目录下。 2、检查硬件是否达到要求 物理RAM必须大于512M,现在的机器内存都没问题。超过8GB RAM时,swap应该在物理RAM的0.75倍以上。Enterprise Edition安装类型大约使用2G硬盘空间。 通过以下命令检查,如果不满足需要做相应的调整 $grep MemTotal /proc/meminfo //检查物理内存大小 $grep SwapTotal /proc/meminfo //检查swap大小 $df -h //检查可用硬件空间大小 3

Whats the difference between sed -E and sed -e

由 扶醉桌前 提交于 2019-12-17 09:46:49
问题 I'm working on some old code and I found that I used to use sed -E 's/findText/replaceWith/g' #findText would contain a regex but I now try sed -e 's/findText/replaceWith/g' It seems to do the same thing, or does it? I kinda remember there being a reason I done it but I can't remember and doing "man sed" doesn't help as they don't have anything about -E only -e that doesn't make much sense ether. -e, --expression=script Append the editing commands in script to the end of the editing command
