oracle 手工创建数据库

1, 创建pfile，通cat命令将以#和空格开头的行过滤掉，放到initSID.ora文件中 pfile文件格式为init(sid).ora

cd $ORACLE_HOME/dbs
cat init.ora |grep -v ^# |grep -v ^$>initTESTSVR.ora
2, 修改pfile关键参数,然后创建参数文件中相关的文件夹
*.db_name='TESTSVR'
*.memory_target=400M
*.processes = 150
*.audit_file_dest='/u01/app/oracle/admin/TESTSVR/adump'
*.background_dump_dest='/u01/app/oracle/admin/TESTSVR/bdump'
*.core_dump_dest='/u01/app/oracle/admin/TESTSVR/cdump'
#audit_trail ='db'
*.db_block_size=8192
*.db_domain=''
*.db_recovery_file_dest='/u01/app/oracle/flash_recovery_area'
*.db_recovery_file_dest_size=2G
*.diagnostic_dest='/u01/app/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=ORCLXDB)'
*.open_cursors=300
*.remote_login_passwordfile='EXCLUSIVE'
*.undo_tablespace='UNDOTBS1'
*.control_files = (/u02/datafile/ora_control01,/u02/datafile/ora_control02)
*.compatible ='11.2.0'
3, 使用pfile启动到nomount状态，通过create database命令创建数据库
create spfile from pfile

create database TESTSVR
CONTROLFILE REUSE
MAXINSTANCES 8
MAXDATAFILES 100
MAXLOGHISTORY 1
MAXLOGFILES 16

group 2 ('/u02/oradata/TESTSVR/onlinelog/redo2.log') size 50M reuse,
group 3 ('/u02/oradata/TESTSVR/onlinelog/redo3.log') size 50M reuse

undo tablespace undotbs1 datafile '/u02/datafile/dbf/undotbs1.dbf' size 100M reuse autoextend on next 10M maxsize unlimited
USER SYS IDENTIFIED BY "oracle" USER SYSTEM IDENTIFIED BY "oracle";

4, 创建完成后数据库自动open，执行下面2个脚本
SQL>@$ORACLE_HOME/rdbms/admin/catalog.sql
SQL>@$ORACLE_HOME/rdbms/admin/catproc.sql

5, 使用spfile自动数据库

SQL> select status from v$instance;

STATUS
------------
OPEN

1 row selected.

SQL> create spfile from pfile;

File created.

SQL> shutdown immediate;

SQL> startup;
SQL> show parameter spfile;

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
_restore_spfile string
spfile string /u01/product/10.2.0/db_2/dbs/s
