ORACLE RAC 手动建库

环境

11.2.0.1 RAC

前提条件

Grid Infrastructure已经安装 ASM已经创建 DB软件已经安装

通过手动创建RAC可以更深的理解单实例DB和RAC DB 的一些区别,在DBCA无法使用的场景中，也需要手动的方式创建,创建步骤如下:

大概思路:先创建单实例DB再转为RAC DB

1. 创建目录

mkdir -p /u01/app/oracle/admin/orcl/adump

2. 编辑参数文件

*.audit_file_dest='/u01/app/oracle/admin/orcl/adump'

*.audit_trail='db'

*.control_files=’+DATA/orcl/controlfile/control01.ctl’, ‘+DATA/orcl/controlfile/control02.ctl’

*.db_block_size=8192

*.db_create_file_dest='+DATA'

*.db_domain=''

*.db_name='orcl'

*.db_recovery_file_dest='+DATA'

*.db_recovery_file_dest_size=10737418240

*.diagnostic_dest='/u01/app/oracle'

*.memory_target=1658847232

*.open_cursors=300

*.processes=150

*.remote_listener='scanip:1521'

*.remote_login_passwordfile='exclusive'

3. 创建ASM目录和创建spfile

[oracle@node1 ~]$ export ORACLE_SID=orcl1

[oracle@node1 ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Thu Dec 12 08:03:22 2013

Connected to an idle instance.

SQL> create spfile='+DATA/orcl/spfileorcl.ora' from pfile='/home/oracle/orcl.ora';

create spfile='+DATA/orcl/spfileorcl.ora' from pfile='/home/oracle/orcl.ora'

ERROR at line 1:

ORA-17502: ksfdcre:4 Failed to create file +DATA/orcl/spfileorcl.ora

ORA-15056: additional error message

ORA-17502: ksfdcre:4 Failed to create file +DATA/orcl/spfileorcl.ora

ORA-15173: entry 'orcl' does not exist in directory '/'

ORA-06512: at line 4

SQL> exit

Disconnected

[oracle@node1 ~]$ su - grid

Password:

su: incorrect password

[oracle@node1 ~]$ su - grid

Password:

[grid@node1 ~]$ asmcmd

ASMCMD> ls

CRS/

DATA/

ASMCMD> cd DATA

ASMCMD> ls

RACDB/

ASMCMD> mkdir ORCL

ASMCMD> exit

[grid@node1 ~]$

[grid@node1 ~]$ exit

logout

[oracle@node1 ~]$ export ORACLE_SID=orcl1

[oracle@node1 ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Thu Dec 12 08:05:10 2013

Connected to an idle instance.

SQL> create spfile='+DATA/orcl/spfileorcl.ora' from pfile='/home/oracle/orcl.ora';

File created.

SQL>

创建init文件

节点1

vi initorcl1.ora

SPFILE='+DATA/orcl/spfileorcl.ora'

节点2

vi initorcl2.ora

SPFILE='+DATA/orcl/spfileorcl.ora'

4. 创建密码文件

cd $ORACLE_HOME/dbs

节点1

orapwd file=orapwORCL1 password=oracle

节点

orapwd file=orapwORCL2 password=oracle

5. 创建DB

CREATE DATABASE orcl

USER SYS IDENTIFIED BY oracle

USER SYSTEM IDENTIFIED BY oracle

LOGFILE GROUP 1 SIZE 100M,

GROUP 2 SIZE 100M,

GROUP 3 SIZE 100M

MAXLOGFILES 5

MAXLOGMEMBERS 5

MAXLOGHISTORY 1

MAXDATAFILES 100

CHARACTER SET US7ASCII

NATIONAL CHARACTER SET AL16UTF16

EXTENT MANAGEMENT LOCAL

DATAFILE SIZE 325M

SYSAUX DATAFILE SIZE 325M

DEFAULT TABLESPACE users

DATAFILE

SIZE 500M AUTOEXTEND ON MAXSIZE UNLIMITED

DEFAULT TEMPORARY TABLESPACE tempts1

TEMPFILE

SIZE 20M

UNDO TABLESPACE undotbs1

DATAFILE

SIZE 200M AUTOEXTEND ON MAXSIZE UNLIMITED;

6. 创建undo 和添加redo

CREATE UNDO TABLESPACE UNDOTBS2 DATAFILE SIZE 200M;

ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 4 SIZE 100M;

ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 5 SIZE 100M;

ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 6 SIZE 100M;

(以下转单实例db到RAC DB)

7. 添加rac 参数

*.cluster_database=true

orcl1.instance_number=1

orcl2.instance_number=2

orcl2.thread=2

orcl1.thread=1

orcl1.undo_tablespace='UNDOTBS1'

orcl2.undo_tablespace='UNDOTBS2'

8. 启动所有节点实例

[oracle@node1 ~]$ sqlplus / as sysdba

SQL> startup

ORACLE instance started.

Total System Global Area 1653518336 bytes

Fixed Size 2213896 bytes

Variable Size 956303352 bytes

Database Buffers 687865856 bytes

Redo Buffers 7135232 bytes

Database mounted.

Database opened.

SQL> ALTER DATABASE ENABLE PUBLIC THREAD 2;

Database altered.

[oracle@node1 ~]$

[oracle@node1 ~]$ ssh node2

Last login: Thu Dec 12 09:43:51 2013 from node1

[oracle@node2 ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Thu Dec 12 10:00:33 2013

Connected to an idle instance.

SQL> startup

ORACLE instance started.

Total System Global Area 1653518336 bytes

Fixed Size 2213896 bytes

Variable Size 956303352 bytes

Database Buffers 687865856 bytes

Redo Buffers 7135232 bytes

Database mounted.

Database opened.

SQL>

SQL> select instance_name from gv$instance;

INSTANCE_NAME

----------------

orcl2

orcl1

9. 执行创建数据字典脚本

@$ORACLE_HOME/rdbms/admin/catalog.sql

@$ORACLE_HOME/rdbms/admin/catproc.sql

@$ORACLE_HOME/rdbms/admin/catclust.sql

--rac 相关字典

@$ORACLE_HOME/rdbms/admin/utlrp.sql

10. 注册数据库到Clusterware

[oracle@node1 ~]$ srvctl add database -d orcl -o $ORACLE_HOME

[oracle@node1 ~]$ srvctl add instance -d orcl -i orcl1 -n node1

[oracle@node1 ~]$ srvctl add instance -d orcl -i orcl2 -n node2

[oracle@node1 ~]$ srvctl enable database -d orcl

PRCC-1010 : orcl was already enabled

[oracle@node1 ~]$ srvctl start database -d orcl

[grid@node1 ~]$ crsctl stat res -t
