Section 1: 数据库和网络配置
1. Database Setup and Undo Management
1.1 Run the minimum required scripts to complete the basic configuration of PROD database .
@?/rdbms/admin/catalog.sql和@?/rdbms/admin/catproc.sql
1.2 Set up automatic undo management in the PROD database to support the following requirements :
1.2.1 Avoid ORA-01555 Snapshot too old errors for queries running up to 90 minutes on
average .
1.2.2 The number of concurrent OLTP users will be approximately 120 during normal business hours .
1.2.3 The number of concurrent batch processes that will run in the evenings and weekings will be approximately 12 to 15 . 更改参数设置
Alter system set undo_retention=5400(1.2.1); (show parameter unto) 使以上参数生效:
Alter tablespace undotbs retention guarantee(1.2.1);
(select tablespace_name,retention from dba_tablespaces;)
2. Server-side Network Configuration
2.1. Create a listener using the default listener name .
2.1.1 The TCP/IP protocol will be used for all connections.Use the machine name (not the IP address) for host. 2.1.2 This listener will listener on the default port.
2.1.3 Database: PROD and EMREP (created later) will be serviced by this listener. SID_LIST_LISTENER = (SID_LIST = (SID_DESC =
(SID_NAME =emrep )
(ORACLE_HOME = /oracle/product/10.2.0/db_1) (PROGRAM = extproc) ) )
LISTENER =
(DESCRIPTION_LIST = (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = test)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0)) ) )
2.2 Add a second listener,named LSNR2,which will listen on port 1526,Configure this listener to support only automatic instance registrations.
2.2.1 Set up the PROD instance to automatically register with the LSNR2. #SID_LIST_LSNR2 = # (SID_LIST = # (SID_DESC =
# (SID_NAME = PROD )
# (ORACLE_HOME = /oracle/product/10.2.0/db_1) # ) # )
LSNR2 =
(DESCRIPTION_LIST = (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = test)(PORT = 1526)) ) )
2.3 Start both listeners. LSNR_2 =
(DESCRIPTION = (ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = test)(PORT = 1526)) )
(CONNECT_DATA =
(SERVICE_NAME = LSNR_2) ) )
需要在tnsnames.ora里配置: prod_2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1526))
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1521)) –将dispatcher也注册到1521的监听上
)
alter system set local_listener=?prod_2?(2.2.1) alter system regitster(2.2.1) lsnrctl start lsnrctl start lsnr2
3. Shared Server Configuartion
3.1 Configure the PROD database to support up to 300 sessions,reserving 100 for dedicated connection.
SQL> alter system set sessions=300 scope=spfile ;
SQL> alter system set shared_server_sessions=200 scope=both; 3.2 Configure the PROD database to support. 3.2.1 Default of 3 TCP dispatchers
SQL>alter system set dispatchers=\TCHERS=3)\scope=both;
alter system set dispatchers=\alter system set dispatchers=\
* LISTENER参数和local_listener参数都可以设定pmon进程将把dispatcher注册到哪个listener上去,但是dispatchers参数的子参数LISTENER优先于local_listener的配
置。 3.2.2 Maximum of 10 dispatchers
SQL> alter system set max_dispatchers=10 scope=both;
3.3.Configure the PROD database to support: 3.3.1 Minimum of 10 shared server processes
SQL> alter system set shared_servers=10 scope=both;
3.3.2 Maximum of 30 shared server processes
SQL> alter system set max_shared_servers=30 scope=both;
4. Client-side Network configuartion
4.1. Create the client-side network configuration files providing connect descriptors to your databases using local naming and easy connect methods. 4.1.1 The prod alias should connect to the PROD instance using the default listener and always use a dedicated server connection.
prod =
(DESCRIPTION = (ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = test)(PORT = 1521)) )
(CONNECT_DATA =
(SERVER = DEDICATED) (SERVICE_NAME = PROD) ) )
4.1.2 The prod_s alias should connect to the PROD instance using LSNR2 and use a shared server connection.
prod_s =
(DESCRIPTION = (ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = test)(PORT = 1526)) )
(CONNECT_DATA = (SERVER = SHARED)
(SERVICE_NAME = PROD) ) )
*******************************************
用户通过prod_s连接上来后,查询session目前连接的结果如下: SYS>select sid, server from v$session;
SID SERVER ---------- ---------
277 DEDICATED 278 NONE
279 DEDICATED 281 DEDICATED
NONE就代表了通过dispatcher连接上来的session,当前没有执行会话,如果执行了
会话,就会变为shared。
4.2. The racdb alias should connect to the RACDB service (created later) with a dedicated server connection. 4.2.1 The RACDB service will be running on your RAC Cluster.
racdb =
(DESCRIPTION = (ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = rac2)(PORT = 1521)) )
(CONNECT_DATA =
(SERVICE_NAME = RACDB) ) )
4.3. The emrep alias should connect to the EMREP instance instance (created later) with a dedicated server connection.
emrep =
(DESCRIPTION = (ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = test)(PORT = 1521)) )
(CONNECT_DATA =
(SERVICE_NAME = EMREP) ) )
5. Tablespace Creation and Configuration
Note:Tablespaces must be named as specified in each task to receive credit .
5.1 Create a temporary tablespace group that contains two(2) temporary tablespaces to support batch processing.the creation of large indexes, and analyzing tables.Use the following specifications: 5.1.1Temporary tablespace group named TEMP_GRP containing temporary tablespaces TEMP1 and TEMP2.
create temporary tablespace temp1
tempfile '/oracle/oradata/temp1_01_grp.dbf' size 20m AUTOEXTEND ON MAXSIZE UNLIMITED tablespace group TEMP_GRP ;
create temporary tablespace temp2
tempfile '/oracle/oradata/temp2_01_grp.dbf' size 20m AUTOEXTEND ON MAXSIZE UNLIMITED tablespace group TEMP_GRP ;
5.1.2 Make TEMP_GRP the default temporary tablespace for all new users.
alter database default temporary tablespace TEMP_GRP; (SQL> select * from dba_tablespace_groups;)
5.2 Create a permanent tablespace to store sample test data.Use the following specifications: 5.2.1 Tablespace name of EXAMPLE 5.2.2 Inital datafile size of 400MB with the file expected to grow to 4TB. 5.2.3 Initial extent size of 1MB 5.2.4 Next extent size of 1MB

Working with LOB Data
1. Create a new tablespace named LOB_DATA in the PROD database to store lob data and lob indexes with the following specifications:
1.1 Create 2 datafiles each in a different location. 1.2 Each file should be 64MB in size. 1.3 Block size 16KB
1.4 Determine which type of extent management would be best for lob data and configure the extents appropriately.
方法一:在Sqlplus中用命令行创建:
create tablespace LOB_DATA datafile '/u01/app/oracle/oradata/PROD/Disk1/lob_data01.dbf' size 64M
autoextend on next 2M,
'/u01/app/oracle/oradata/PROD/Disk2/lob_data02.dbf' size 64M autoextend on next 2M
extent management local uniform size 2M segment space management auto blocksize 16k;
将以上创建LOB_DATA表空间的脚本保存为lob_data.sql,然后在Sqlplus中运行lob_data.sql [oracle@rac1 scripts]$ sqlplus sys/oracle@prod as sysdba

2. Create a new table in the HR schema in the PROD database with the following specifications: 2.1 Table name ORACLE9I_REFERENCES 2.2 Tablespace USERS 2.3 Table structure:
2.3.1 ORACLE9I_ARTICLE ROWID
2.3.2 INSERT_TIME TIMESTAMP WITH LOCAL TIME ZONE
3. For any row in the HR.MAGAZINE_ARTICLES table that contains three or more references to Oracle9i insert the corresponding rowid and a timestamp for the time that it was inserted into the ORACLE9I_REFERENCES table.
CREATE TABLE \(
\
\ TIMESTAMP WITH LOCAL TIME ZONE )
