1.jsp调用oracle
| 1.安装tomcat [root@h1 ROOT]# cd /var/App/ [root@h1 App]# unzip apache-tomcat-6.0.14.zip 2.复制ojdbc.jar [root@h1 ~]# cd /app/oracle/product/11.2.0/dbhome_2/jdbc/lib [root@h1 webapps]# cd /var/App/apache-tomcat-6.0.14/webapps/ROOT
<%
<% out.println("Hello,Everybody"); "1.jsp" [New] 17L, 81C written 3.安装jdk，修改/etc/profile [root@h1 ROOT]# cd /var/App/ [root@h1 APP]# ./jdk-6u27-linux-x64.bin [root@h1 App]#vi /etc/profile export JAVA_HOME=/var/App/jdk1.6.0_27 "/etc/profile" 84L, 1905C written windwos 下修改系统环境变量 用户环境变量添加JAVA_HOME 系统环境变量添加CLASSPATH=%JAVA_HME%\lib 系统环境变量添加PATH=.;%JAVA_HME%\bin; 4.启动tomcat [root@h1 bin]# cd /var/App/apache-tomcat-6.0.14/bin [root@h1 bin]# ./startup.sh [root@h1 ROOT]# cd /var/App/apache-tomcat-6.0.14/webapps/ROOT [root@h1 ROOT]# vi [root@h1 ROOT]# vi db.jsp <%@ page contentType="text/html;charset=gbk" import="java.sql.*"%> <% ~

2.冷·备份
前提：有两台服务器,一台是oracle数据库服务器SERVER130 ip=192.168.5.130，另一台是新机 Server128=192.168.5.128
现在冷备份数据库将Server130中的TEST迁移至Server128
#-------------------其中SERVER130 数据库重命名过，原名ORCL，所以按照数据库安装时生成的/app/oracle/admin/orcl/pfile/
init.ora.[num]中db_name=安装数据库时的ORCL；迁移次文件，生成的数据库是ORCL

3.备份概念
差异备份:备份自上一次完全备份之后有变化的数据
增量备份:备份自上一次备份（包含完全备份、差异备份、增量备份）之后有变化的数据
RMAN备份:
用恢复管理器备份数据文件、控制文件、归档日志和SPFILE的方法。
RMAN是由目标数据库的服务器进程执行备份操作。
因为RMAN备份由目标数据库的服务器进程来完成，所以当使用RMAN执行备份操作时，目标数据库必须处于MOUNT状态或OPEN状态。
