RAC 手工建库

如果在创建库的时候，用DBCA有问题，有时候通过修改AIO可以解决，有时候环境复杂，修改aio也没效果，那么，可以尝试手工建库（当然，如果连手工建库都还有03113错误，那么很可能说明AIO是太小了，呵呵），或者其他原因导致你的dbca不能用，那么可以尝试手工建库，然后动态的加节点进去，下面是一个试验过程：
 
在两个节点做:
创建所需的目录（要和init.ora中的相应设置对应）：
mkdir /oracle/admin/cin/bdump;
mkdir /oracle/admin/cin/cdump;
mkdir /oracle/admin/cin/create;
mkdir /oracle/admin/cin/pfile;
mkdir /oracle/admin/cin/udump;
 
检查环境变量（主要看SID要和init.ora中的实例名对应）：
[m80b]/oracle/dbs> env | grep ORA
ORACLE_BASE=/oracle
ORACLE_SID=cin1
ORACLE_TERM=xterm
ORA_NLS33=/oracle/ocommon/nls/admin/data
ORACLE_HOME=/oracle
[m80b]/oracle/dbs> 
 
[m80a]/oracle/dbs> env | grep ORA
ORACLE_BASE=/oracle
ORACLE_SID=cin2
ORACLE_TERM=xterm
ORA_NLS33=/oracle/ocommon/nls/admin/data
ORACLE_HOME=/oracle
[m80a]/oracle/dbs> 
 
编辑/etc/oratab文件：
把 *:/oracle:Y 改成 cin:/oracle:Y
 
创建口令文件（这一步可以不做，如果不创建口令文件后面需要用os认证连接）：
[m80a]/oracle/bin/orapwd file=/oracle/dbs/orapwcin2 password=change_on_install
 
[m80b]/oracle/bin/orapwd file=/oracle/dbs/orapwcin1 password=change_on_install
 
以下的过程在一台机器上做就可以了：

/oracle/bin/sqlplus /nolog @/oracle/admin/cin/scripts/CreateDB.sql
================
connect SYS/change_on_install as SYSDBA
set echo on
spool /oracle/admin/cin/create/CreateDB.log
startup nomount pfile="/oracle/admin/cin/pfile/initcin.ora";

ok，成功，可以加入第2个节点了：
 
在另一台机器上做：
