Oracle Study之-Oracle 11g OCM考试（1）

Oracle Study之-Oracle 11g OCM考试（1）系统环境：RedHat EL64
Oracle： Oracle 11gR2
Oracle 11g OCM考试第一题，手工建库，参考文档

。参考人员必须对文档非常熟悉，才可以在指定的时间内完成任务。

一、查看系统环境
[oracle@rh64 ~]$ cat .bash_profile

# .bash_profile
export EDITOR=vi
export ORACLE_SID=prod
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
umask 022

[oracle@rh64 ~]$ id oracle
uid=300(oracle) gid=501(oinstall) groups=501(oinstall),502(dba)
2、建立数据库pfile文件
[oracle@rh64 dbs]$ pwd
/u01/app/oracle/product/11.2.0/db_1/dbs
[oracle@rh64 dbs]$ ls
hc_DBUA3908922.dat init.bk inittest2.ora lkTEST2 orapwtest2
hc_prod.dat initDBUA3908922.ora inittest.ora orapwDBUA3908922 snapcf_prod.f
hc_test2.dat init.ora lkPROD orapwprod spfileprod.ora
hc_test.dat initprod.ora lkTEST orapwtest spfiletest2.ora
[oracle@rh64 dbs]$ cat init.ora |grep -v "^#"|grep -v "^$" >inittest1.ora
编辑pfile文件：
[oracle@rh64 dbs]$ cat inittest1.ora

db_name='test1'
memory_target=300m
processes = 150
audit_file_dest='$ORACLE_BASE/admin/test1/adump'
audit_trail ='db'
db_block_size=8192
db_domain=''
diagnostic_dest=$ORACLE_BASE
open_cursors=300
remote_login_passwordfile='EXCLUSIVE'
undo_tablespace='UNDOTBS1'
control_files ='/u01/app/oracle/oradata/test1/control01.ctl'
compatible ='11.2.0'

建立相应的目录：
[oracle@rh64 dbs]$ mkdir -p /u01/app/oracle/admin/test1/adump
[oracle@rh64 dbs]$ mkdir -p /u01/app/oracle/oradata/test1
建立 Instance 口令文件：
[oracle@rh64 dbs]$ orapwd file=orapwtest1 password=oracle entries=3

建立建库脚本：

参考：



[oracle@rh64 ~]$ cat cr_db.sql

CREATE DATABASE test1
USER SYS IDENTIFIED BY oracle
USER SYSTEM IDENTIFIED BY oracle
LOGFILE GROUP 1 ('/u01/app/oracle/oradata/test1/redo01a.log') SIZE 100M BLOCKSIZE 512,
GROUP 2 ('/u01/app/oracle/oradata/test1/redo02a.log') SIZE 100M BLOCKSIZE 512
MAXLOGFILES 5
MAXLOGMEMBERS 5
MAXLOGHISTORY 1
MAXDATAFILES 100
CHARACTER SET zhs16gbk
EXTENT MANAGEMENT LOCAL
DATAFILE '/u01/app/oracle/oradata/test1/system01.dbf' SIZE 325M REUSE
SYSAUX DATAFILE '/u01/app/oracle/oradata/test1/sysaux01.dbf' SIZE 325M REUSE
DEFAULT TEMPORARY TABLESPACE tempts1
TEMPFILE '/u01/app/oracle/oradata/test1/temp01.dbf'
SIZE 20M REUSE
UNDO TABLESPACE undotbs1
DATAFILE '/u01/app/oracle/oradata/test1/undotbs01.dbf'
SIZE 200M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;

3、启动Instance到nomount，运行建库脚本：
[oracle@rh64 ~]$ export ORACLE_SID=test1

[oracle@rh64 ~]$ sqlplus '/as sysdba'
SQL*Plus: Release 11.2.0.3.0 Production on Fri Apr 8 17:09:02 2016
Copyright (c) 1982, 2011, Oracle.  All rights reserved.
Connected to an idle instance.
17:09:02 SYS@ test1>startup nomount;
ORACLE instance started.
Total System Global Area  313159680 bytes
Fixed Size                  2227944 bytes
Variable Size             218104088 bytes
Database Buffers           88080384 bytes
Redo Buffers                4747264 bytes
17:14:17 SYS@ test1>select status from v$instance；
STATUS
------------
STARTED

17:15:15 SYS@ test1>@/home/oracle/cr_db.sql
Database created.
4、建库完成后，通过脚本建立数据字典
[oracle@rh64 ~]$ cat cr_dict.sql
@?/rdbms/admin/catalog.sql
@?/rdbms/admin/catproc.sql
conn system/oracle
@?/sqlplus/admin/pupbld.sql
17:31:44 SYS@ test1>@/home/oracle/cr_dict.sql
5、建库成功，建立default tablespace
19:24:34 SYSTEM@ test1>create tablespace users
datafile '/u01/app/oracle/oradata/test1/users01.dbf' size 100m;
Tablespace created.
19:25:57 SYSTEM@ test1>alter database default tablespace users;
Database altered.
19:27:52 SYSTEM@ test1>select tablespace_name,file_id,file_name from dba_data_files;

TABLESPACE_NAME                   FILE_ID FILE_NAME
------------------------------ ---------- --------------------------------
SYSTEM                                  1 /u01/app/oracle/oradata/test1/system01.dbf
SYSAUX                                  2 /u01/app/oracle/oradata/test1/sysaux01.dbf
UNDOTBS1                                3 /u01/app/oracle/oradata/test1/undotbs01.dbf
USERS                                   4 /u01/app/oracle/oradata/test1/users01.dbf
4 rows selected.

6、配置网络（tnsnames）
[oracle@rh64 admin]$ cat tnsnames.ora

TEST1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rh64)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = test1)
)
)

[oracle@rh64 admin]$ lsnrctl status
