Oracle12c在Win10上的安装配置实践
Oracle12c在Win10上的安装配置实践1、环境操作系统：Win10专业版（64位）数据库：Oracle 12c Release 2（Version 12.2.0.1.0，64位）2、下载Oracle12c3、安装3.1、右键以管理员⾝份运⾏setup.exe3.2、配置安全更新在安装界⾯⾥，取消勾选“我希望通过My Oracle Support接收安全更新”，点击下⼀步。
提⽰出现尚未提供电⼦邮件地址，选择是。
3.3、安装选项选择“创建和配置数据库”（默认），点击下⼀步。
3.4、系统类选择“桌⾯类”（默认），如果是安装到服务器上，请选择“服务器类”，点击下⼀步。
3.5、Oracle主⽬录⽤户使⽤虚拟账户：⽤于 Oracle 数据库单实例安装的 Oracle 主⽬录⽤户。
使⽤现有windows⽤户：如果选择该项，则需要指定没有管理权限的⽤户。
创建新Windows⽤户：创建⼀个新⽤户，输⼊⽤户名和密码，这个新建的⽤户没有Windows登录权限。
使⽤Windows内置账户：微软在开Windows时预先为⽤户设置的能够登录系统的账户。
此处本⼈选择虚拟账户，也是oracle的官⽅建议之⼀。
注意：如果选择第⼆项，创建的⽤户名和已有的不能发⽣冲突，否则后⾯的安装会报错！3.6、典型安装设置oracle安装位置，字符集选择AL32UTF8或者ZHS16GBK，设置密码，如果密码过于简单会报警告，忽略即可，点击下⼀步。
注意：字符集AL32UTF8，sqlplus会存在乱码问题，需要配置TNS环境变量。
本⽂后⾯有字符集如何更改相关内容。
图省事的话建议此处选择ZHS16GBK字符集。
3.7、先决条件检查3.8、概要3.93.104、测试Oracle是否安装成功两种⽅式4.1、SQL Plus4.2、em5、相关问题5.1、PLSQL Developer⽆法连接64位Oracle数据库5.1.1、PLSQL数据库选项为空如图所⽰：原因在于：PLSQL不可以直接连接64位Oracle数据库，只能连接32位的。
oracle12c安装教程linux
oracle12c安装教程linux一、安装环境准备1、操作系统：Oracle 12c 支持的操作系统：（1）Linux x86-64 (Red Hat Enterprise Linux 5、6、7、Oracle Linux 5、6、7、Suse Linux Enterprise Server 11 SP2）（2）Solaris x86-64 (Solaris 11.2)（3）AIX 7.12、硬件环境：（1）CPU：双核或更多（2）内存：2GB以上（3）硬盘：至少有4GB的空闲空间二、安装步骤1、下载安装文件从官网下载Oracle 12c的安装文件，本文以linux x86-64为例，安装文件名为linuxx64_12201_database.zip。
2、解压安装文件将下载的安装文件解压到指定的安装目录，本文以/opt/oracle/product/12.2/dbhome_1为例，解压后的文件如下：[oracle@localhost ~]$ ls -l /opt/oracle/product/12.2/dbhome_1total 20drwxr-xr-x 4 oracle oinstall 4096 Apr 24 17:43 cdrom-rwxr-xr-x 1 oracle oinstall 1219 Apr 24 17:43 .ouidrwxr-xr-x 2 oracle oinstall 4096 Apr 24 17:43 installdrwxr-xr-x 2 oracle oinstall 4096 Apr 24 17:43 response-rwxr-xr-x 1 oracle oinstall 735 Apr 24 17:43 runInstaller3、添加用户为了安装Oracle 12c，需要添加一个用户，本文以oracle为例：[oracle@localhost ~]$ groupadd oinstall[oracle@localhost ~]$ groupadd dba[oracle@localhost ~]$ useradd -g oinstall -G dba oracle[oracle@localhost ~]$ passwd oracle4、设置环境变量为了方便使用，需要设置环境变量，本文以oracle为例：[oracle@localhost ~]$ vi .bash_profile# Oracle Settingsexport ORACLE_HOME=/opt/oracle/product/12.2/dbhome_1 export ORACLE_SID=orclexport ORACLE_BASE=/opt/oracleexport ORACLE_TERM=xtermexport PATH=$ORACLE_HOME/bin:$PATHexport LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib exportCLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms /jlib5、安装Oracle 12c使用root用户登录，进入安装目录，执行安装程序：[oracle@localhost ~]$ su - root[root@localhost ~]。
