假设数据库软件已经安装好，现在没有图形界面无法用dbca安装数据库，那么用手工建库，数据库名为edw
创建目录
[oracle@localhost ~]$ mkdir -p /u01/app/oracle/admin/edw/adump [oracle@localhost ~]$ mkdir -p /u01/app/oracle/oradata/edw [oracle@localhost ~]$ mkdir -p /u01/app/oracle/flash_recovery_area
创建密码文件
[oracle@localhost ~]$ dbs [oracle@localhost /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs]$ orapwd file=orapwedw password=oracle entries=30
创建参数文件pfile
[oracle@localhost /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs]$ cat init.ora | grep -v ^# | grep -v ^$ > initedw.ora
然后vim做一些替换操作
:%s/ORCL/edw/g :%s/orcl/edw/g :%s##$ORACLE_BASE#g :%s#ora_control1#/u01/app/oracle/oradata/edw/ora_control1.ctl#g :%s#ora_control2#/u01/app/oracle/oradata/edw/ora_control2.ctl#g
得到的pfile如下
[oracle@localhost /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs]$ cat initedw.ora db_name='edw' memory_target=1G processes = 150 audit_file_dest='$ORACLE_BASE/admin/edw/adump' audit_trail ='db' db_block_size=8192 db_domain='' db_recovery_file_dest='$ORACLE_BASE/flash_recovery_area' db_recovery_file_dest_size=2G diagnostic_dest='$ORACLE_BASE' dispatchers='(PROTOCOL=TCP) (SERVICE=edwXDB)' open_cursors=300 remote_login_passwordfile='EXCLUSIVE' undo_tablespace='UNDOTBS1' control_files = (/u01/app/oracle/oradata/edw/ora_control1.ctl, /u01/app/oracle/oradata/edw/ora_control2.ctl) compatible ='11.2.0' [oracle@localhost /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs]$
启动到nomount根据pfile生成spfile
[oracle@localhost /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs]$ export ORACLE_SID=edw [oracle@localhost /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs]$ sql SQL*Plus: Release 11.2.0.4.0 Production on Thu Nov 21 16:49:38 2019 Copyright (c) 1982, 2013, Oracle.

创建数据库
从官方文档Administrator's Guide –> 2 Creating and Configuring an Oracle Database –> Creating a Database with the CREATE DATABASE Statement –> Step 9: Issue the CREATE DATABASE Statement 复制建库语句然后做些vim替换操作
:%s/mynewdb/edw/g :%s/sys_password/oracle/g :%s/system_password/oracle/g :%s#/u01/logs/my/#/u01/app/oracle/oradata/edw/#g :%s#/u02/logs/my/#/u01/app/oracle/oradata/edw/#g :%s/US7ASCII/AL32UTF8/g :%s/undotbs/undotbs1/g
得到的建库语句是
[oracle@localhost /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs]$ cat crtdb.sql
