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
LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 08-APR-2016 19:33:50 Copyright (c) 1991, 2011, Oracle. All rights reserved. Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=rh64)(PORT=1521))) STATUS of the LISTENER ------------------------ Alias LISTENER Version TNSLSNR for Linux: Version 11.2.0.3.0 - Production Start Date 08-APR-2016 19:32:48 Uptime 0 days 0 hr. 1 min. 2 sec Trace Level off Security ON: Local OS Authentication SNMP OFF Listener Parameter File /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora Listener Log File /u01/app/oracle/diag/tnslsnr/rh64/listener/alert/log.xml Listening Endpoints Summary...

测试网络连接：
[oracle@rh64 admin]$ sqlplus system/oracle@test1
SQL*Plus: Release 11.2.0.3.0 Production on Fri Apr 8 19:34:27 2016 Copyright (c) 1982, 2011, Oracle. All rights reserved. Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options
19:34:27 SYSTEM@ test1>
----- 至此，手工建库成功；如果有时间，可以对数据库做一个冷备 。
