select tablespace_name, file_id, file_name, round(bytes/(1024*1024),0) total_space from dba_data_files where tablespace_name='UMS_LOG2' order by 3,1;

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

6、查临时表空间对应的数据文件路径

select tablespace_name, file_id, file_name, round(bytes/(1024*1024),0) total_space from dba_temp_files order by tablespace_name,file_name;

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

7、查看表大小

select owner,segment_name,segment_type,bytes/1024/1024 from dba_segments where segment_name='MSG_SYSTEM_BAK';

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

8、扩大原表空间的大小

ALTER DATABASE DATAFILE '/oradata/orc11/system01.dbf' RESIZE 4G;

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

9、增加一个新的表空间文件

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

21、基于Linux的命令行环境下创建Oracle10gR2数据库

环境：RHEL 5.3＋Oracle10g Release 2

1．设置系统环境变量：

ORACLE_HOME=/usr/local/oracle/app

ORACLE_BASE=/usr/local/oracle

2．系统规划：

实例名称：ORACLE_SID=typtdb

数据库名称：typtdb

3．手工创建如下目录：

mkdir -p /usr/local/oracle/admin/typtdb/cdump

mkdir -p /usr/local/oracle/admin/typtdb/bdump

mkdir -p /usr/local/oracle/admin/typtdb/udump

mkdir -p /usr/local/oracle/admin/typtdb/pfile

4．建立密码文件：

/usr/local/oracle/app/bin/orapwd file=/usr/local/oracle/app/dbs/orapwdtyptdb password=typtdb

5．修改参数文件：

格式：/usr/local/oracle/app/dbs/init.ora

实例：/usr/local/oracle/app/dbs/inittyptdb.ora

内容如下：

large_pool_size=4294967296

shared_pool_size=4294967296

core_dump_dest='/usr/local/oracle/admin/typtdb/cdump'

db_block_size=8192

db_file_multiblock_read_count=16

db_name='typtdb'

db_recovery_file_dest='/usr/local/oracle/flash_recovery_area'

db_recovery_file_dest_size=2147483648

dispatchers='(PROTOCOL=TCP) (SERVICE=typtdbXDB)'

job_queue_processes=1000

open_cursors=300

pga_aggregate_target=8589934592

processes=3000

undo_management='auto'

undo_tablespace='undotbs1'

user_dump_dest='/usr/local/oracle/admin/typtdb/udump'

NLS_DATE_FORMAT="Mon DD YYYY HH24:MI:SS"

NLS_DATE_LANGUAGE=AMERICAN

control_files = (/usr/local/oracle/oradata/typtdb/ora_control1.ctl, /usr/local/oracle/oradata/typtdb/ora_control2.ctl,/usr/local/oracle/oradata/typtdb/ora_control3ctl)

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

或则使用如下内容

*.audit_file_dest='/usr/local/oracle/admin/typtdb/adump'

*.background_dump_dest='/usr/local/oracle/admin/typtdb/bdump'

*.compatible='10.2.0.3.0'

*.control_files='/usr/local/oracle/oradata/typtdb/control01.ctl','/usr/local/oracle/oradata/typtdb/control02.ctl','/usr/local/oracle/oradata/typtdb/control03.ctl'

*.core_dump_dest='/usr/local/oracle/admin/typtdb/cdump'

*.db_block_size=8192

*.db_domain=''

*.db_file_multiblock_read_count=16

*.db_name='typtdb'

*.dispatchers='(PROTOCOL=TCP) (SERVICE=typtdbXDB)'

*.job_queue_processes=10

*.log_archive_dest='/usr/local/oracle/oradata/typtdb/archlog'

*.nls_language='AMERICAN'

*.open_cursors=5000

#PGA设置为(total_mem * 80%) * 20%

*.pga_aggregate_target=2748779070

*.processes=1000

*.remote_login_passwordfile='EXCLUSIVE'

#SGA设置为(total_mem * 80%) * 80%

*.sga_max_size=10995116278

*.sga_target=10995116278

*.undo_management='AUTO'

*.undo_tablespace='UNDOTBS1'

*.user_dump_dest='/usr/local/oracle/admin/typtdb/udump'

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

6．设置当前工作实例：

export ORACLE_SID=typtdb

7．登陆oracle：

>sqlplus sys/typtdb as sysdba

8．启动实例：

SQL>startup nomount pfile="/usr/local/oracle/app/dbs/inittyptdb.ora"

9．创建数据库的脚本：

--创建数据库

create database typtdb

logfile group 1 '/usr/local/oracle/oradata/typtdb/redo01.log' size 128m reuse,

group 2 '/usr/local/oracle/oradata/typtdb/redo02.log' size 128m reuse,

group 3 '/usr/local/oracle/oradata/typtdb/redo03.log' size 128m reuse

datafile '/usr/local/oracle/oradata/typtdb/typtdb01.dbf' size 5120m reuse

maxdatafiles 100

archivelog

character set ZHS16GBK

sysaux datafile '/usr/local/oracle/oradata/typtdb/sys01.dbf' size 512m

undo tablespace undotbs1 datafile '/usr/local/oracle/oradata/typtdb/undo01.dbf' size 1024m;

--创建临时表空间

create temporary tablespace temp tempfile '/usr/local/oracle/oradata/typtdb/temp01.dbf' size 2048m;

--创建回退段表空间

create tablespace rbs datafile '/usr/local/oracle/oradata/typtdb/rbs01.dbf' size 512m;

--创建工具表空间

create tablespace tools datafile '/usr/local/oracle/oradata/typtdb/tools01.dbf' size 512m;

--创建索引表空间

create tablespace indx datafile '/usr/local/oracle/oradata/typtdb/indx01.dbf' size 512m;

--回退段设置

create public rollback segment rbs0 tablespace rbs storage (optimal 4096k) ;

create public rollback segment rbs1 tablespace rbs storage (optimal 4096k) ;

create public rollback segment rbs2 tablespace rbs storage (optimal 4096k) ;

create public rollback segment rbs3 tablespace rbs storage (optimal 4096k) ;

--启动回退段

alter rollback segment "rbs0" online ;

alter rollback segment "rbs1" online ;

alter rollback segment "rbs2" online ;

alter rollback segment "rbs3" online ;

--创建用户表空间

create tablespace userdata datafile '/usr/local/oracle/oradata/typtdb/userdata01.dbf' size 1024m ;

--创建用户

create user orauser identified by orauser default tablespace userdata temporary tablespace temp;

--给用户授权

grant connect,resource to orauser;

10．运行如下文件：

(1). 运行sql创建系统表/视图和过程:

--创建系统常用的数据字典视图和同义词

@?/rdbms/admin/catalog.sql

--运行服务器端所需要的PL/SQL脚本

@?/rdbms/admin/catproc.sql

connect system/manager

--创建PRODUCT_USER_PROFILE表，用于禁止某些用户使用SQLPLUS访问数据库

@?/sqlplus/admin/pupbld.sql

(2). 切换到archivelog模式

shutdown immediate

startup mount

alter database archivelog;

archive log start

alter database open;

(3).从pfile创建spfile

sqlplus '/as sysdba'

create spfile from pfile;

11．经验总结：

①inittyptdb.ora中的control_files关键字所指示的目录必需存在。

②inittyptdb.ora中undo_tablespace中的名字必需与Create Database中的相同。

③分析数据库出错可以到/usr/local/oracle/admin/typtdb/bdump目录下的alert_typtdb.log中查找。

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

22、oracle修改游标大小

这个问题最好是通过优化sql来解决，考试,大提示也可以通过修改ORACLE的参数open_cursors 来解决。

（1）oraclehome\admin\数据库名字\pfile 下面的init.ora里面有参数

#游标和库高速缓存#

open_cursors=300

（2）Oracle9i以上版本可通过

SQL>conn sys as sysdba

SQL>show parameter open_cursors;

SQL>alter system set open_cursors=4000 scope=both;

（3）重启系统使它生效。

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

23、ORACLE 中修改用户密码的方法

用OS认证方式登陆，即是CONNECT / AS SYSDBA 登陆，然后修改密码就是了

ALTER USER backup IDENTIFIED BY "bcinfobackup";

ALTER USER SYSTEM IDENTIFIED BY ****

然后你可以改变成密码文件认证。

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

24、自动清理归档日志

#!/bin/bash

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

26、查询当前执行IO最多的sql，并按大到小来排序

select cast(buffer_gets/decode(EXECUTions,0,10000,EXECUTions) as int) 平均IO ,

EXECUTions 执行次数,buffer_gets 总逻辑IO,disk_reads 硬盘读取, sql_text SQl语句

from v$sqlarea

where parsing_schema_name='MOMA'

and rownum<=10

order by buffer_gets desc ;

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

27、hp unix 启动监听命令

srvctl start listener -n db1

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

28、关闭Oracle快闪功能

YP >shutdown immediate;

Database closed.

Database dismounted.

ORACLE instance shut down.

YP >startup mount;

ORACLE instance started.

Total System Global Area 314572800 bytes

Fixed Size 1301704 bytes

Variable Size 261890872 bytes

Database Buffers 50331648 bytes

Database mounted.

YP >alter database flashback off;

Database altered.

YP >alter database open;

Database altered.

YP >alter system set log_archive_dest_1='LOCATION=/usr/local/oracle/archivelog1' scope=both;

Database altered.

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

29、修改快闪区大小

alter system set db_recovery_file_dest_size=50G scope=both;

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

30、oracle11g 查看日志命令

adrci

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

31、Oracle修改日志组文件的大小

1、创建2个新的日志组

alter database add logfile group 4 ('/oradata/qfman/redo04.log') size 1G;

alter database add logfile group 5 ('/oradata/qfman/redo05.log') size 1G;

2、切换当前日志到新的日志组

alter system switch logfile;

或直接切换归档

alter system archive log current;

3、删除旧的日志组

alter database drop logfile group 1;

alter database drop logfile group 2;

alter database drop logfile group 3;

4、操作系统下删除原日志组1、2、3中的文件

rm -rf /oradata/qfman/redo01.log

rm -rf /oradata/qfman/redo02.log

rm -rf /oradata/qfman/redo03.log

5、重建日志组1、2、3

alter database add logfile group 1 ('/oradata/qfman/redo01.log') size 1G;

alter database add logfile group 2 ('/oradata/qfman/redo02.log') size 1G;

alter database add logfile group 3 ('/oradata/qfman/redo03.log') size 1G;

6、切换日志组

alter system switch logfile;

7、删除中间过渡用的日志组4、5

alter database drop logfile group 4;

alter database drop logfile group 5;

8、到操作系统下删除原日志组4、5中的文件

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

32、用于查询出占用资源较高的进程的HASH值

while [ 1 ]

echo "SESSION EVENT WAIT LIST "

sqlplus -S '/as sysdba' <<EOF

set pagesize 2000

set linesize 800

col event format a29

col program format a29

col sess_sql_hash for a15

col username for a11

col client for a31

select substr(a.event,1,25) event,substr(b.program,1,39) program ,b.sid||':'||decode(sql_hash_value,0,prev_hash_value,sql_hash_value) sess_sql_hash,b.username

,substr(b.osuser||'@'||b.machine||'@'||b.process||'@'||c.spid,1,31) client,to_char(b.logon_time,'mm-dd hh24:mi') logon_time

from v\$session_wait a,v\$session b,v\$process c

where a.sid=b.sid and b.paddr=c.addr

and a.event not like '%SQL%'

and a.event not like '%message%'

and a.event not like '%time%'

and a.event not like 'PX Deq:%'

and a.event not like 'jobq slave%'

exit

EOF

sleep 5

done

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

33、用于根据HASH值查询相应的SQL语句

sqlplus -S '/as sysdba' <<EOF

variable v_hash_value Number;

BEGIN

:v_hash_value :=$1;

END;

set pages 0

set lines 1000

set feedback off

set term on

select to_char(sysdate,'yyyymmdd hh24:mi:ss') as curtime,hash_value,sql_text from v\$sqltext where hashvalue=:v_hash_value order by piece;

exit

EOF

---------------------------------------------------------------------------------------------------------------------------------34、查看数据库是否存在死锁

select /*+ NO_MERGE(a) NO_MERGE(b) NO_MERGE(c) */ 'Wait' "Status", a.username, a.machine, a.sid, a.serial#, a.last_call_et "Seconds", b.id1, c.sql_text "SQL"

from v$session a, v$lock b, v$sqltext c

where a.username is not null

and a.lockwait = b.kaddr

and c.hash_value =a.sql_hash_value

union

from v$session a, v$lock b, v$sqltext c

where b.id1 in

(select /*+ NO_MERGE(d) NO_MERGE(e) */ distinct e.id1

from v$session d, v$lock e

where d.lockwait = e.kaddr)

and a.username is not null

and a.sid = b.sid

and b.request=0

and c.hash_value =a.sql_hash_value;

select t2.username||' '||t2.sid||' '||t2.serial#||' '||t2.logon_time||' '||t3.sql_text

from v$locked_object t1,v$session t2,v$sqltext t3

where t1.session_id=t2.sid

and t2.sql_address=t3.address

order by t2.logon_time;

SELECT /*+ rule */ s.username,

decode(l.type,'TM','TABLE LOCK',

'TX','ROW LOCK',

NULL) LOCK_LEVEL,

o.owner,o.object_name,o.object_type,

s.sid,s.serial#,s.terminal,s.machine,s.program,s.osuser

FROM v$session s,v$lock l,dba_objects o

WHERE l.sid = s.sid

AND l.id1 = o.object_id(+)

AND s.username is NOT NULL;

select distinct s.SID,s.SERIAL#,a.owner,a.object_name,q.SQL_TEXT,s.paddr,p.SPID

from v$locked_object l,all_objects a,v$session s,v$sql q,v$process p

where l.OBJECT_ID=a.object_id

and s.SID=l.SESSION_ID

and q.ADDRESS=s.PREV_SQL_ADDR

and s.PADDR=p.ADDR

36、使用RAC的Oracle软件安装数据库时，出现如下情况时

ORA-29702: error occurred in Cluster Group Service operation

需关闭RAC的动态链接

关闭

cd $ORACLE_HOME/rdbms/lib

make -f ins_rdbms.mk rac_off

make -f ins_rdbms.mk ioracle

打开

cd $ORACLE_HOME/rdbms/lib

make -f ins_rdbms.mk rac_on

make -f ins_rdbms.mk ioracle

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

37、impdp/expdp使用实例

一、创建逻辑目录，该命令不会在操作系统创建真正的目录，最好以system等管理员创建。

create directory dpdata1 as 'd:\test\dump';

二、查看管理理员目录（同时查看操作系统是否存在，因为Oracle并不关心该目录是否存在，如果不存在，则出错）

select * from dba_directories;

三、给scott用户赋予在指定目录的操作权限，最好以system等管理员赋予。

grant read,write on directory dpdata1 to scott;

四、导出数据

1)按用户导

expdp scott/tiger@orcl schemas=scott dumpfile=expdp.dmp DIRECTORY=dpdata1;

2)并行进程parallel

expdp scott/tiger@orcl directory=dpdata1 dumpfile=scott3.dmp parallel=40 job_name=scott3

3)按表名导

expdp scott/tiger@orcl TABLES=emp,dept dumpfile=expdp.dmp DIRECTORY=dpdata1;

4)按查询条件导

expdp scott/tiger@orcl directory=dpdata1 dumpfile=expdp.dmp Tables=emp query='WHERE deptno=20';

5)按表空间导

expdp system/manager DIRECTORY=dpdata1 DUMPFILE=tablespace.dmp TABLESPACES=temp,example;

6)导整个数据库

expdp system/manager DIRECTORY=dpdata1 DUMPFILE=full.dmp FULL=y;

五、还原数据

1)导到指定用户下

impdp scott/tiger DIRECTORY=dpdata1 DUMPFILE=expdp.dmp SCHEMAS=scott;

2)改变表的owner

impdp system/manager DIRECTORY=dpdata1 DUMPFILE=expdp.dmp TABLES=scott.dept REMAP_SCHEMA=scott:system;

3)导入表空间

impdp system/manager DIRECTORY=dpdata1 DUMPFILE=tablespace.dmp TABLESPACES=example;

4)导入数据库

impdb system/manager DIRECTORY=dump_dir DUMPFILE=full.dmp FULL=y;

5)追加数据

impdp system/manager DIRECTORY=dpdata1 DUMPFILE=expdp.dmp SCHEMAS=system TABLE_EXISTS_ACTION=append;

如果导出和导入的用户名和表空间名不一样，则使用如下命令

impdp noep/xbwesrU3tN directory=dump_dir dumpfile=noep_test.dmp logfile=impdp_noep.log remap_schema=noep_test:noep remap_tablespace=noep_test:noep_data

impdp的remap使用说明

总结：impdp导入到目标数据库中，需要确保目标数据库中存在源数据库中的用户和用户所属表空间都存在，否则需要使用remap参数。

如：

情景一：

源数据库：create user test identified by test default tablespace ts_test;

目标数据库：create user test identified by test default tablespace ts_test1;（表空间不同）

这样必须加remap_tablespace=ts_test:ts_test1

情景二：

源数据库：create user test identified by test default tablespace ts_test;

目标数据库：create user test2 identified by test default tablespace ts_test1;(用户和表空间都不同)

这样必须加remap_schema=test:test2 remap_tablespace=ts_test:ts_test1

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

38、修改RAC数据库的归档的默认路径：

SQL> select inst_id,instance_name,version,archiver,status from gv$instance;

INST_ID INSTANCE_NAME VERSION ARCHIVE STATUS

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

1 pushdb1 10.2.0.4.0 STARTED OPEN

2 pushdb2 10.2.0.4.0 STARTED OPEN

SQL> alter system set log_archive_dest_1='location=/oracle/product/archivelog1' sid='pushdb1';

System altered.

SQL> alter system set log_archive_dest_1='location=/oracle/product/archivelog2' sid='pushdb2';

System altered.

SQL> show parameter log_archive

NAME TYPE VALUE

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

log_archive_config string

log_archive_dest string

log_archive_dest_1 string location=/oracle/product/archivelog1

log_archive_dest_10 string

... ....

39、CRS及相关服务的常用命令的演示

查看状态的命令

# su – oracle --先切换到oracle用户

$ crs_stat -t --查看crs及所有的service的状态

$ crsctl check crs --用crsctl命令，检查crs相关服务的状态

$ srvctl status nodeapps -n db01 (db02) --使用srvctl查看所有节点上的服务是否正常

$ srvctl status database -d db --使用srvctl查看数据库状态

启动和关闭相关服务的命令

# su – oracle

$ crs_start –all --启动所有的crs服务

$ crs_stop –all --停止所有的crs服务

$ crsctl start crs --启动crs服务

$ crsctl stop crs --停止crs服务

$ srvctl start nodeapps -n db01(db02) --启动某节点上所有的应用

$ srvctl stop nodeapps -n db01(db02) --停止某节点上所有的应用

$ srvctl start listener -n db01(db02) --启动某个节点的listener

$ srvctl stop listener -n db01(db02) --停止某个节点的listener

$ srvctl start instance –d db –i db01(db02) --启动某个instance

$ srvctl stop instance –d db –i db01(db02) --停止某个instance

$ srvctl start database –d db --启动数据库

$ srvctl stop database –d db --停止数据库

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

40、Oracle RAC停开机器顺序标准做法

开机顺序：

srvctl start nodeapps -n <node1 hostname>

srvctl start nodeapps -n <node2 hostname>

srvctl start asm -n <node1 hostname>

srvctl start asm -n <node2 hostname>

srvctl start database -d <database name>

srvctl start service -d <database name> -s <service name>

关闭顺序：　

srvctl stop service -d <database name> -s <service name>

srvctl stop database -d <database name>

srvctl stop asm -n <node1 hostname>

srvctl stop asm -n <node2 hostname>

srvctl stop nodeapps -n <node1 hostname>

srvctl stop nodeapps -n <node2 hostname>

如果某些服务没有启动

手工SHUTDOWN 每个实例

然后CRS_STOP -ALL，关闭其他服务。

启动的时候可以通过CRS_START -ALL启动
