linux Oracle安装
，可以写一个启动脚本ora10g： 以root身份进入，编写以下脚本：#!/bin/bash
#
# chkconfig: 2345 91 19
# description: starts the oracle listener and instance
status() {
pid=`ps -ef | grep ora_pmon | grep -v grep | awk '{print $8}'`
if [ "X$pid" = "X" ]
then
echo "oracle10g is not running."
exit 1
else
echo "oracle10g is running."
exit 0
fi
}
case "$1" in
start)
#startup the listener and instance
echo -n "oracle begin to startup: "
su - oracle -c "lsnrctl start"
su - oracle -c dbstart
echo "oracle10g started"
;;
stop)
# stop listener, apache and database
echo -n "oracle begin to shutdown:"
su - oracle -c "lsnrctl stop"
su - oracle -c dbshut
echo "oracle10g shutdowned"
;;
reload|restart)
$0 stop
$0 start
;;
'status')
status
;;
*)
echo "Usage: ora10g "
exit 1
esac
exit 0
存为ora10g后，然后
chmod a+x ora10g
ln -s /opt/oracle/product/10.2.0/bin/ora10g /etc/rc.d/init.d/
即可在以后以root身份运行/etc/rc.d/init.d/ora10g start |stop 来管oracle的启动和停止了。
如果要将这个脚本加入到系统中使其可开机运行，那么要运行以下命令：
chkconfig --level 345 ora10g on
或者可在/etc/rc.d/rc.local中加入如下：
su - oracle -c "lsnrctl start"
su - oracle -c "dbstart"
6, 关于数据库删除重新安装的问题:
把ORACLE安装目录删除及/etc/ora*.*删除就行了
#rm –f /etc/ora*.*
7.修改Oracle10g数据库字符集
SQL> connect sys/oracle as sysdba
SQL> startup mount
SQL> alter session set sql_trace=true;
Session altered.
SQL> alter system enable restricted session;
System altered.
SQL> alter system set job_queue_processes=0;
System altered.
SQL> alter system set aq_tm_processes=0;
System altered.
SQL> alter database open;
Database altered.
SQL> set linesize 120;
SQL> alter database character set zhs16gbk;
alter database character set zhs16gbk
*
ERROR at line 1:
ORA-12712: new character set must be a superset of old character set
SQL> ALTER DATABASE character set INTERNAL_USE zhs16gbk; # 使用INTERNAL_USE可以跳过超集的检查,ALTER DATABASE character set INTERNAL_USE
Database altered.
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> STARTUP
SQL> select name,value$ from props$ where name like '%NLS%';

8. oracle database备份
(1)vi bachupDb.sh
#!/bin/sh
#oracle用户下
#crontab -e 增加 "35 4 * * * /home/oracle/dbbackup/backupDb.sh",保存后自动安装
#或echo "35 4 * * * /home/oracle/dbbackup/backupDb.sh" > backupDb.cron
#crontab backupDb.cron
#############
#@tip 修改为本机数据库home目录
export ORACLE_HOME=/opt/oracle/product/10g
export PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin
# 注意字符集必须和数据库的字符集一致，以避免字符集转化失败
export NLS_LANG=AMERICAN_AMERICA.zhs16gbk
#@tip 125修改为要备份的oracle的ip地址的最后一段
dmpfile="`echo ~/`dbbackup/gedb_`date +%w`.dmp"
logfile="`echo ~/`dbbackup/gedb_`date +%w`.log"
if [ -w $dmpfile ]
then
echo "rm -f $dmpfile"
rm -f "$dmpfile"
fi
#@tip ip地址修改为要备份的oracle的主机地址
exp USERID=gedb/gedb@10.248.1.5/ge01 file=$dmpfile log=$logfile owner=gedb grants=y
(2)copy bachupDb.sh 到slave oracle srever 相应目录,
chown oracle.oinstall bachupDb.sh
chmod 744 bachupDb.sh
vi bachupDb.sh 以符合安装情况
(3)以oracle user role
crontab -e
35 4 * * * /home/oracle/dbbackup/backupDb.sh
9. restore oracle backup
su - oracle
imp USERID=gedb/gedb file=gedb_6.dmp log=implogfile commit=y grants=y full=y
