数据库创建

来源：互联网发布：网络医托编辑：程序博客网时间：2024/04/30 15:25

手工创建数据库（包括oracle rac）

最简单的方法就是使用dbca来生产建库的脚本，然后手工执行这些脚本。具体过程如下

1,手工创建相关目录和环境变量

[sql]

#!/bin/sh

OLD_UMASK=`umask`

umask 0027

mkdir -p /oracle/app/oracle/admin/hrdb/adump

mkdir -p /oracle/app/oracle/admin/hrdb/dpdump

mkdir -p /oracle/app/oracle/admin/hrdb/hdump

mkdir -p /oracle/app/oracle/admin/hrdb/pfile

mkdir -p /oracle/app/oracle/cfgtoollogs/dbca/hrdb

umask ${OLD_UMASK} www.2cto.com

ORACLE_SID=hrdb1; export ORACLE_SID

PATH=$ORACLE_HOME/bin:$PATH; export PATH

是否使用数据库自动启动，这里设置为false

echo You should Add this entry in the /etc/oratab: hrdb:/oracle/app/oracle/product/11.2.0/db_1:N

2，创建参数文件、密码文件

[sql]

密码文件

/oracle/app/oracle/product/11.2.0/db_1/bin/orapwd file=/oracle/app/oracle/product/11.2.0/db_1/dbs/orapwhrdb1 force=y

参数文件$ORACLE_HOME/dbs/inithrdb1.ora

*.audit_file_dest='/oracle/app/oracle/admin/hrdb/adump'

*.audit_trail='db'

*.cluster_database=false

*.compatible='11.2.0.0.0'

*.cpu_count=8

*.create_stored_outlines=''

*.db_block_size=8192

*.db_create_file_dest='+DATA'

*.db_domain=''

*.db_name='hrdb'

*.db_recovery_file_dest='+FRA'

*.db_recovery_file_dest_size=107374182400

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

hrdb1.instance_number=1

*.log_archive_format='%t_%s_%r.dbf'

*.nls_language='SIMPLIFIED CHINESE'

*.nls_territory='CHINA'

*.open_cursors=1000

*.pga_aggregate_target=1610612736

*.processes=500 www.2cto.com

*.remote_listener='dtydb-scan2:1521'

*.sga_target=4399824896

启动到nomount状态

sqlplus "/as sysdba"

startup nomount pfile="/oracle/app/oracle/product/11.2.0/db_1/dbs/inithrdb1.ora";

3，开始建库

[sql]

CREATE DATABASE "hrdb"

MAXINSTANCES 32

MAXLOGHISTORY 1

MAXLOGFILES 192

MAXLOGMEMBERS 3

MAXDATAFILES 1024

DATAFILE SIZE 700M AUTOEXTEND ON NEXT 10240K MAXSIZE UNLIMITED

EXTENT MANAGEMENT LOCAL

SYSAUX DATAFILE SIZE 600M AUTOEXTEND ON NEXT 10240K MAXSIZE UNLIMITED

SMALLFILE DEFAULT TEMPORARY TABLESPACE TEMP TEMPFILE SIZE 20M AUTOEXTEND ON NEXT 640K MAXSIZE UNLIMITED

SMALLFILE UNDO TABLESPACE "UNDOTBS1" DATAFILE SIZE 1024M AUTOEXTEND ON NEXT 5120K MAXSIZE UNLIMITED

CHARACTER SET ZHS16GBK

NATIONAL CHARACTER SET AL16UTF16

LOGFILE GROUP 1 SIZE 512M,

GROUP 2 SIZE 512M,

GROUP 7 SIZE 512M

USER SYS IDENTIFIED BY oracle USER SYSTEM IDENTIFIED BY oracle;

4，参数文件中添加控制文件选项

[sql]

hrdb1>column ctl_files NEW_VALUE ctl_files;

hrdb1>select concat('control_files=''', concat(replace(value, ', ', ''','''), '''')) ctl_files from v$parameter where name ='control_files';

www.2cto.com

CTL_FILES

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

control_files='+DATA/hrdb/controlfile/current.388.791301537','+FRA/hrdb/controlfile/current.361.791301537'

host echo &ctl_files >> /oracle/app/oracle/product/11.2.0/db_1/dbs/inithrdb1.ora;

5，创建数据字典

[sql]

connect / as sysdba;

spool /tmp/CreateDBCatalog.log append

@/oracle/app/oracle/product/11.2.0/db_1/rdbms/admin/catalog.sql;

@/oracle/app/oracle/product/11.2.0/db_1/rdbms/admin/catblock.sql;

@/oracle/app/oracle/product/11.2.0/db_1/rdbms/admin/catproc.sql;

@/oracle/app/oracle/product/11.2.0/db_1/rdbms/admin/catoctk.sql;

@/oracle/app/oracle/product/11.2.0/db_1/rdbms/admin/owminst.plb;

spool off

connect "SYSTEM"/"oracle"

spool /tmp/system.log append

@/oracle/app/oracle/product/11.2.0/db_1/sqlplus/admin/pupbld.sql;

@/oracle/app/oracle/product/11.2.0/db_1/sqlplus/admin/help/hlpbld.sql helpus.sql;

spool off

6，创建spfile，存放于asm磁盘

[sql]

create spfile from pfile='/oracle/app/oracle/product/11.2.0/db_1/dbs/inithrdb1.ora';

cp /oracle/app/oracle/product/11.2.0/db_1/dbs/inithrdb1.ora /oracle/app/oracle/product/11.2.0/db_1/dbs/inithrdb1.ora.bak

echo "SPFILE='+DATA/hrdb/spfilehrdb.ora'" > /oracle/app/oracle/product/11.2.0/db_1/dbs/inithrdb1.ora

www.2cto.com

7，psu升级，重新编译

[sql]

spool /tmp/postDBCreation.log append

@/oracle/app/oracle/product/11.2.0/db_1/rdbms/admin/catbundle.sql psu apply;

select 'utl_recomp_begin: ' || to_char(sysdate, 'HH:MI:SS') from dual;

execute utl_recomp.recomp_serial();

select 'utl_recomp_end: ' || to_char(sysdate, 'HH:MI:SS') from dual;

8，重新启动，从spfile文件启动，修改为归档模式

[sql]

shutdown immediate;

connect "SYS"/"&&sysPassword" as SYSDBA

startup mount pfile="/oracle/app/oracle/admin/hrdb/scripts/init.ora";

startup mount;

alter database archivelog;

alter database open;

单实例的数据库已经正常启动了，如果是rac数据库，还需要以下过程

9、添加log file和undo

[sql]

<span style="font-size:12px;">--添加log thread 3

ALTER DATABASE ADD LOGFILE THREAD 3

GROUP 5 SIZE 512M,

GROUP 6 SIZE 512M,

GROUP 9 SIZE 512M;

ALTER DATABASE ENABLE PUBLIC THREAD 3;

--添加log thread 3

ALTER DATABASE ADD LOGFILE THREAD 2

GROUP 3 SIZE 512M, www.2cto.com

GROUP 4 SIZE 512M,

GROUP 8 SIZE 512M;

ALTER DATABASE ENABLE PUBLIC THREAD 2;

undo tablespace

CREATE SMALLFILE UNDO TABLESPACE "UNDOTBS2" DATAFILE SIZE 1024M AUTOEXTEND ON NEXT 5120K MAXSIZE UNLIMITED;

CREATE SMALLFILE UNDO TABLESPACE "UNDOTBS3" DATAFILE SIZE 1024M AUTOEXTEND ON NEXT 5120K MAXSIZE UNLIMITED;</span>

10，CreateClustDBViews

[sql]

spool /oracle/app/oracle/admin/epmdb/scripts/CreateClustDBViews.log append

@/oracle/app/oracle/product/11.2.0/db_1/rdbms/admin/catclust.sql;

spool off

11，修改rac相关的参数

[sql]

alter system set cluster_database=true scope=spfile;

alter system set remote_listener="dtydb-scan2:1521" scope=spfile;

alter system set instance_number=2 scope=spfile sid='hrdb2';

alter system set instance_number=3 scope=spfile sid='hrdb3';

alter system set thread=2 scope=spfile sid='hrdb2';

alter system set thread=3 scope=spfile sid='hrdb3';

alter system set undo_tablespace=UNDOTBS2 scope=spfile sid='hrdb2';

alter system set undo_tablespace=UNDOTBS3 scope=spfile sid='hrdb3';

create pfile = '/tmp/init.ora' from spfile;

create spfile='+DATA/hrdb/spfilehrdb.ora' FROM pfile ='/tmp/init.ora';

www.2cto.com

也可通过修改pfile文件完成

epmdb3.instance_number=3

epmdb2.instance_number=2

epmdb1.instance_number=1

epmdb3.thread=3

epmdb2.thread=2

epmdb1.thread=1

epmdb3.undo_tablespace=UNDOTBS3

epmdb1.undo_tablespace=UNDOTBS1

epmdb2.undo_tablespace=UNDOTBS2

12，删除默认的spfile，让数据库从pfile启动，实际从asm上的spfile上启动

[sql]

shutdown immediate;

mv spfilehrdb1.ora spfilehrdb1.ora.bak

db2上

vi inithrdb2.ora

SPFILE='+DATA/hrdb/spfilehrdb.ora'

db3上

vi inithrdb3.ora

SPFILE='+DATA/hrdb/spfilehrdb.ora'

13，注册到crs中

[sql]

/oracle/11.2.0/grid/bin/setasmgidwrap o=/oracle/app/oracle/product/11.2.0/db_1/bin/oracle

oracle/app/oracle/product/11.2.0/db_1/bin/srvctl add database -d hrdb -o /oracle/app/oracle/product/11.2.0/db_1 -p +DATA/hrdb/spfilehrdb.ora -n hrdb -a DATA,FRA www.2cto.com

/oracle/app/oracle/product/11.2.0/db_1/bin/srvctl add instance -d hrdb -i hrdb1 -n dtydb3

/oracle/app/oracle/product/11.2.0/db_1/bin/srvctl add instance -d hrdb -i hrdb2 -n dtydb4

/oracle/app/oracle/product/11.2.0/db_1/bin/srvctl add instance -d hrdb -i hrdb3 -n dtydb5

/oracle/app/oracle/product/11.2.0/db_1/bin/srvctl enable database -d hrdb;

/oracle/app/oracle/product/11.2.0/db_1/bin/srvctl start database -d hrdb;
