ORACLE 管理常用命令

编辑文件/etc/sysctl.conf,具体配制与操作系统不同而不同,本实例在SUSE-LINUX 32位8C,16G通过

kernel.shmall = 2097152

kernel.shmmax = 34359738368

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 65536

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default = 262144 // 256K

net.core.rmem_max = 1048576 // 1M

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

创建ORACLE用户,最好用orarun包创建用户

groupadd -g 400 oinstall

groupadd -g 401 dba

useradd -u 400 -g oinstall -G dba -c "Oracle Software Owner" oracle

设置编码

export LC_ALL=c

export DISPLAY=155.20.25.189:0.0

编辑文件/etc/profile

./runInstaller -ignoresysprereqs

安装完成

1.修改过initsid.ora. 注释修改后的参数

2.如果是spfile,则:

sqlplus /as sysdba

create pfile fromo spfile;

create spfile from pfile;

设置SGA

alter system set sga_target=160M;

alter system set sga_max_size=16384M;

create spfile from pfile='/opt/oracle/product/10.2/db_1/dbs/init.ora'

alter system reset sort_area_size scope=spfile sid='*' #从spfile中移出sort_area_size

create spfile='/tmp/pfile.tst' from spfile

startup pfile='**/init.ora'

添加执行权限

chmod a+x ./oracle

变更所有权

chown -R oracle:dba ./oracle

启动控制台

./emctl start dbConsole

vi $ORACLE_HOME/../dbs/ vi initeygle.ora修改sga大小

启动Listener

./lsnrctl start

启动网络配制

./netmgr

sysctl -a

如果出现:TNS-12555

chmod 777 /var/tmp/.oracle

LANG="zh_CN.GB18030"

反安装ORACLE

3.停止Listener

[oracle@ora920 oracle]$ lsnrctl stop

4.停止HTTP服务

[oracle@ora920 oracle]$ $ORACLE_HOME/Apache/Apache/bin/apachectl stop

5.用su或者重新登录到root(如想重新安装可以保留oracle用户，省得输入环境变量了)

6.将安装目录删除

[root@ora920 /root]# rm -rf /opt/oracle/

7.将/usr/bin下的文件删除

[root@ora920 /root]# rm /usr/bin/dbhome

[root@ora920 /root]# rm /usr/bin/oraenv

[root@ora920 /root]# rm /usr/bin/coraenv

8.将/etc/oratab删除

[root@ora920 /root]# rm /etc/oratab

9.将/etc/oraInst.loc删除

[root@ora920 /root]# rm /etc/oraInst.loc

10.将oracle用户删除(若要重新安装,可以不删除)

[root@ora920 /root]# userdel –r oracle

11.将用户组删除(若要重新安装,可以不删除)

[root@ora920 /root]# groupdel oinstall

[root@ora920 /root]# groupdel dba

12.将启动服务删除

[root@ora920 /root]# chkconfig --del dbora

/home/oracle/oraInventory/orainstRoot.sh

/home/oracle/product/10.2.0/db_1/root.sh

------------删除oracle10g--------------

1. 运行 $ORACLE_HOME/bin/localconfig delete

2. rm -rf $ORACLE_BASE/*

3. rm -f /etc/oraInst.loc /etc/oratab

4. rm -rf /etc/oracle

5. rm -f /etc/inittab.cssd

6. rm -f /usr/local/bin/coraenv /usr/local/bin/dbhome /usr/local/bin/oraenv

修改oracle参数

alter system set xxx=xxx scope=spfile;

shutdown immediate;

startup;

设置oracle归档:

sqlplus ‘/ as sysdba’

alter system set log_archive_dest_1=’location=/yang/arch’ scope=spfile;

alter system set log_archive_start=TRUE scope=spfile;

alter system set log_archive_format=’ arch%t_%s_%r.arc’ scope=spfile;

shutdown immediate;

startup mount;

alter database archivelog;

alter database open;

数据库置为归档模式后，可以按如下方式检验一下：

SQL> archive log list

#将logminer的数据字典从system表空间转移到新建的表空间，防止撑满system表空间

execute dbms_logmnr_d.set_tablespace('tbs_stream');

创建表空间:

create tablespace tbs_stream datafile '+VGDATA/h10g/datafile/tbs_stream01.dbf'

size 100m autoextend on maxsize unlimited segment space management auto;

创建用户:

create user strmadmin identified by strmadmin

default tablespace tbs_stream temporary tablespace temp;

授权用户:

#授权Stream管理用户

grant connect,resource,dba,aq_administrator_role to strmadmin;

#启用Database 追加日志

alter database add supplemental log data;

#启用Table追加日志

alter table add supplement log group log_group_name(table_column_name) always;

#建立数据库链

create database link h10g connect to strmadmin identified by strmadmin using 'h10g';

ASM

ASM新建,扩表空间

create tablespace cdweb_index datafile size 10G;

alter tablespace cdweb_index add datafile size 10G;

//ASM安装

/etc/init.d/oracleasm configure

This will configure the on-boot properties of the Oracle ASM library

driver. The following questions will determine whether the driver is

loaded on boot and what permissions it will have. The current values

will be shown in brackets ('[]'). Hitting <ENTER> without typing an

answer will keep that current value. Ctrl-C will abort.

Default user to own the driver interface []: oracle

Default group to own the driver interface []: dba

ASM安装日志:

155.20.16.15上dm-0~13全部做了asm-disk

155.20.16.18上dm-0~1做了asm-disk,dm2~3没做.

select name from v$datafile;

select member from v$logfile;

如果没有归档：

shutdown immediate;

startup mount;

alter database archivelog; / alter database noarchivelog;

alter database open;

archive log list;

删除归档日志：

rman

delete archivelog until time 'sysdate';

ALTER SYSTEM ARCHIVE LOG CURRENT;

恢复到指定时间

run {

restore archivelog from time "to_date('2009-06-05 14:00:00', 'YYYY-MM-DD HH24:MI:SS')";

}

export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss';

recover database until time '2009-06-05 13:00:00';

alter database open resetlogs;

list backup of archivelog from time "to_date('2009-06-01 14:00:00', 'YYYY-MM-DD HH24:MI:SS')";

run

2.7 手工注册归档日志

当有异常发生，远程归档失败后；需要手工归档日志以使capture进程能够继续下去

命令格式：

ALTER DATABASE REGISTER LOGICAL LOGFILE 'D:/oracle/product/10.2.0/oradata/S

ERVICE/ARCHIVE/ARC00065_0676907427.001' for 'CAPTURE_SXLSS';

注意：CAPTURE_SXLSS也要用引号引起来

创建分区表：

create tablespace partitionTestTableSpace

datafile 'partitionTestTableSpace' size 50M

create table niegc_part

(

part_id integer primary key,

part_date date,

part_desc varchar2(100)

)

partition by range(part_date)

(

partition "200906" values less than(to_date('2009-06-30','yyyy-mm-dd')) tablespace partitionTestTableSpace,

partition "200907" values less than(to_date('2009-07-31','yyyy-mm-dd')) tablespace partitionTestTableSpace,

partition "200908" values less than(to_date('2009-08-31','yyyy-mm-dd')) tablespace partitionTestTableSpace

);

修改表空间：

select a.tablespace_name,

a.bytes bytes_used,

b.largest,

round(((a.bytes - b.bytes) / a.bytes) * 100, 2) percent_used

from (select tablespace_name, sum(bytes) bytes

from dba_data_files x

group by tablespace_name) a,

(select tablespace_name, sum(bytes) bytes, max(bytes) largest

from dba_free_space

group by tablespace_name) b

where a.tablespace_name = b.tablespace_name

Order by ((a.bytes - b.bytes) / a.bytes) DESC;
