查看SELinux状态：
1、/usr/sbin/sestatus -v ##如果SELinux status参数为enabled即为开启状态
SELinux status: enabled
2、getenforce ##也可以用这个命令检查
关闭SELinux：
1、临时关闭（不用重启机器）：
setenforce 0 ##设置SELinux 成为permissive模式
##setenforce 1 设置SELinux 成为enforcing模式
2、修改配置文件需要重启机器：
修改/etc/selinux/config 文件
将SELINUX=enforcing改为SELINUX=disabled
重启机器即可

------------------ AIX系统用户解锁
3.1 AIX用户账户锁定与解锁最佳方法
3004-303 There have been too many unsuccessful login attempts; please see
the system administrator.
与之相关的配置参数是/etc/security/login.cfg的以下配置项
logindisable=7 *7次失败登录后锁定端口
logininterval=120 *在120秒内7次失败登录才锁定端口
1、如果你可以登陆到ROOT账户，比较简单
使用chsec命令即可解锁，具体如下：
# chsec -f /etc/security/lastlog -a unsuccessful_login_count=0 -s username
通过重置未成功登陆的次数即可解锁
2、如果是通过设置来锁定的用户，可以这样解锁
#【smitty user】-->【Lock / Unlock a User's Account】
或是
# chsec -f /etc/security/lastlog -a unsuccessful_login_count=0 -s username
3、命令解锁
# chuser account_locked=TRUE username 给用户加锁
# chuser accout_locked=FALSE username 给用户解锁

--------------ORA-00845: MEMORY_TARGET not supported on this system
办法： 修改/etc/fstab
tmpfs /dev/shm tmpfs defaults,size=4G 0 0
[root@FWDB ~]# mount -o remount,size=4G /dev/shm
简单来说就是 MEMORY_MAX_TARGET 的设置不能超过 /dev/shm 的大小：
[oracle@FWDB FWDB]$ df -h | grep shm
tmpfs 2.0G 0 2.0G 0% /dev/shm
马上把它加大：
[root@FWDB ~]# cat /etc/fstab | grep tmpfs
tmpfs /dev/shm tmpfs defaults,size=4G 0 0
现在可以通过重启使这个配置生效，也可以通过重新挂载来修改其大小：
[root@FWDB ~]# mount -o remount,size=4G /dev/shm
[root@FWDB ~]# df -h | grep shm
tmpfs 4.0G 0 4.0G 0% /dev/shm
再次启动数据库，没有报错了。
二、修改/dev/shm大小
默认的最大一半内存大小在某些场合可能不够用，并且默认的inode数量很低一般都要调高些，这时可以用mount命令来管理它。
#mount -o size=1500M -o nr_inodes=1000000 -o noatime,nodiratime -o remount /dev/shm
在2G的机器上，将最大容量调到1.5G，并且inode数量调到1000000，这意味着大致可存入最多一百万个小文件。
如果需要永久修改/dev/shm的值，需要修改/etc/fstab
tmpfs /dev/shm tmpfs defaults,size=1.5G 0 0
mount -o remount /dev/shm
umount tmpfs
mount -t tmpfs shmfs -o size=3000m /dev/shm
vi /etc/fstab
若有的时候不能卸载该目录，报错：“umount: /dev/shm: device is busy.”，则可以用fuser处理：
# fuser -km /dev/shm
# umount /dev/shm
# mount /dev/shm

------------------------------------------------- 修改主机名
永久生效：
[root@zijuan /]# vim /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=zijuan
HOSTNAME=zijuan表示主机设置为zijuan.
注意：修改主机名后，需要重启系统后生效，或者切换个用户然后切换回来就OK
查看/etc/hosts文件中必须包含a fully qualified name for the server
[root@localhost lhr]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.59.140 dg
[root@localhost lhr]# hostname
localhost.localdomain
[root@localhost lhr]# hostname dg
[root@localhost lhr]# hostname
dg
-----归档格式
alter system set log_archive_format = "log_oradg10g_%d_%t_%s_%r.arc" scope=spfile;
---------------------------------------- drop database 删除数据库
1、dbca静默删库：dbca -silent -deleteDatabase -sourceDB mydb
2、SQL窗口：
alter database close;
alter system enable restricted session;
drop database;
3、SQL窗口：
sql > startup force mount restrict;
sql > drop database;
注意：强烈推荐第一种办法，以上2和3的办法若是rac库需要设置cluster_database为false后才可以执行drop database，命令为：alter system set cluster_database=false sid='*' scope=spfile;
-------------------------------------- 配置本地yum源
-----------rhel 6.5
mkdir -p /media/lhr/cdrom
mount /dev/sr0 /media/lhr/cdrom/
#设置开机自动挂载系统镜像文件 vi /etc/fstab 添加以下内容

cd /etc/yum.repos.d/
cp rhel-media.repo rhel-media.repo.bk
vi /etc/yum.repos.d/rhel-media.repo

yum -y remove mysql-libs-5.1.71 --卸载
yum erase mysql-libs-5.1.71 --卸载
yum list | grep mysql
rpm -e --nodeps mysql-libs.x86_64 --强制卸载
-----------------命令后rpm包被下载到了什么地方
每次在执行完yum命令后，系统都会把需要用到的rpm包放在/var/cache/yum/这个目录下，但下载源的不同还是会放在不同源目录下。
find /var/cache/yum/ -name kmod-oracleasm*
--extundelete工具恢复rm -rf 删除的目录(ext4)
-------------- rhel5.5
# mkdir /media/cdromlhr
编辑 /etc/fstab 文件，在文件尾部添加如下内容，以便开机自动挂载光盘：
[root@localhost ~]# tail -1 /etc/fstab
/dev/hdc /media/cdromlhr iso9660 defaults 0 0
[root@localhost ~]#
[root@localhost ~]# mount -a
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@localhost ~]#
清空并编辑 YUM 源配置文件
清空 /etc/yum.repos.d/rhel-debuginfo.repo 文件并新增以下内容：
[root@localhost ~]# cp /etc/yum.repos.d/rhel-debuginfo.repo /etc/yum.repos.d/rhel-debuginfo.repo.bak
[root@localhost ~]# cat /etc/yum.repos.d/rhel-debuginfo.repo
[rhel-debuginfo]
name=Red Hat Enterprise Linux $releasever - $basearch - Debug
baseurl=file:///media/cdromlhr/Server
enabled=1
gpgcheck=0
# vi /etc/yum.repos.d/my.repo
[Oracle]
name=OEL-$releasever – Media
baseurl=file:///mnt/Server
gpgcheck=0
enabled=1
如果是RHEL或者CentOS，请先将/etc/yum.repos.d下面的文件删除或者移动到别的目录下，RHEL创建方法和OEL一样，CentOS则baseurl=file:///mnt/ 即可，因为CentOS的repodata目录就在光盘根下。

[ZFZHLHRDB3:grid]:/home/grid>srvctl add listener -l LISTENER_LHRDG -p 1523 -o $ORACLE_HOME
srvctl config listener -l LISTENER_LHRDG -a
① rac添加LISTENER资源的时候需要使用grid用户
② srvctl config查看资源的具体配置情况
③ srvctl modify可以修改资源的配置
--添加单实例
srvctl add database -d LHRDGPRI -c SINGLE -o /oracle/app/oracle/product/11.2.0/db -p '/oracle/app/oracle/product/11.2.0/db/dbs/spfileLHRDGPHY1.ora' -r physical_standby -n LHRDGPRI -x ZFZHLHRDB1 -i LHRDGPRI
crsctl status resource ora.asm -f
crsctl modify resource ora.asm -attr "GEN_USR_ORA_INST_NAME@SERVERNAME(zfxdeskdb1)=+ASM1"
crsctl modify resource ora.asm -attr "GEN_USR_ORA_INST_NAME@SERVERNAME(zfxdeskdb2)=+ASM2"
srvctl stop asm -f

生产环境下，oracle 9I下sga大概8G，pga大概6g，需要导入一个2.7g以上的大表到成产库中，由于是同事着手运用imp工具的默认buffer=30K，用时大概一个小时还没有结果，考虑到pga还是很大的，跟同事商议加上buffer=409600000设置buffer大概400M的，15分钟内imp完成。当然运用impdp然后运用parallel=n效率当然更加理想了！

1、给表加注释
COMMENT ON TABLE TABLENAME IS '用户表';
2、查看表的COMMENT
SELECT * FROM USER_TAB_COMMENTS WHERE TABLE_NAME='TABLENAME';
3、给字段加注释
COMMENT ON COLUMN TABLENAME.COLNAME IS 'OOXX';
4、查看字段的COMMENT
SELECT * FROM USER_COL_COMMENTS WHERE TABLE_NAME='TABLENAME';

----linux下批量查找/替换文本内容
--一般在本地电脑上批量替换文本有许多工具可以做到，比如sublime text ,但大多服务器上都是无图形界面的，为此收集了几条针对linux命令行 实现批量替换文本内容的命令：
--1.批量查找某个目下文件的包含的内容，例如：
# grep -rn "要找查找的文本" ./
[oracle@rhel6_lhr dpdump]$ grep -rn "ALTER SESSION SET EVENTS" ./
./spool_result.sql:2:ALTER SESSION SET EVENTS '10150 TRACE NAME CONTEXT FOREVER, LEVEL 1';
./spool_result.sql:3:ALTER SESSION SET EVENTS '10904 TRACE NAME CONTEXT FOREVER, LEVEL 1';
./spool_result.sql:4:ALTER SESSION SET EVENTS '25475 TRACE NAME CONTEXT FOREVER, LEVEL 1';
./spool_result.sql:5:ALTER SESSION SET EVENTS '10407 TRACE NAME CONTEXT FOREVER, LEVEL 1';
./spool_result.sql:6:ALTER SESSION SET EVENTS '10851 TRACE NAME CONTEXT FOREVER, LEVEL 1';
./spool_result.sql:7:ALTER SESSION SET EVENTS '22830 TRACE NAME CONTEXT FOREVER, LEVEL 192 ';
--2.批量查找并替换文件内容。
# sed -i "s/要找查找的文本/替换后的文本/g" `grep -rl "要找查找的文本" ./`
例如替换 被病毒修改的一段脚本：
sed -i "s/
