重回blogger，关于sdb的挂载

我的资料库acnis.com域名被xinnet搞瘫后，记录在此

从阵列中获取了一个900G的磁盘空间，挂载到一个/www的挂载点
//运行fdisk -l 获取磁盘信息，得到以下内容
[root@localhost ~]# fdisk -l

Disk /dev/sdb doesn't contain a valid partition table

//运行以下命令进行磁盘格式化
[root@localhost ~]# mke2fs -j /dev/sdb

/dev/sdb is entire device, not just one partition!

oracle10中存在dbstart脚本路径错误 (oracle10启动出错)

oracle10201中存在dbstart脚本路径错误，修改方式如下
Failed to auto-start Oracle Net Listene using /ade/vikrkuma_new/oracle/bin/tnslsnr
修改dbstart的第78行

# Set this to bring up Oracle Net Listener (isher)
ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle
为
ORACLE_HOME_LISTNER=$ORACLE_BASE/db10g

常用还常忘的kudzu服务

kudzu
这个服务是一个检测硬件配置的服务，在每次linux/unix服务器启动时此服务会检测服务器现有硬件配置是否与服务器内文件记载的内容一致，如果不同将会建议管理员设置新硬件的驱动。

如果此服务没有检测到新更新了硬件，可以先删除掉服务器已配置的内容，然后从新启动kudzu命令，进行更新

启动命令
service kudzu start | stop
或
/etc/init.d/kudzu start | stop
