Oracle RAC维护命令

原创 Linux操作系统 作者:ljm0211 时间:2012-06-13 23:46:39 0 删除 编辑

1、查看所有实例和服务的状态

$ srvctl status database -d orcl

Instance orcl1 is running on node linux1

Instance orcl2 is running on node linux2

2、查看单个实例的状态

$ srvctl status instance -d orcl -i orcl2

Instance orcl2 is running on node linux2

3、查看数据库全局命名服务的状态

$ srvctl status service -d orcl -s orcltest

Service orcltest is running on instance(s) orcl2, orcl1

4、查看特定节点上节点应用程序的状态

$ srvctl status nodeapps -n linux1

VIP is running on node: linux1

GSD is running on node: linux1

Listener is running on node: linux1

ONS daemon is running on node: linux1

5、查看ASM 实例的状态

$ srvctl status asm -n linux1

ASM instance +ASM1 is running on node linux1.

6列出配置的所有数据库

$ srvctl config database

orcl

7显示 RAC 数据库的配置

$ srvctl config database -d orcl

linux1 orcl1 /u01/app/oracle/product/10.2.0/db_1

linux2 orcl2 /u01/app/oracle/product/10.2.0/db_1

8显示指定集群数据库的所有服务

$ srvctl config service -d orcl

orcltest PREF: orcl2 orcl1 AVAIL:

9显示节点应用程序的配置 —(VIPGSDONS、监听器)

$ srvctl config nodeapps -n linux1 -a -g -s -l

VIP exists.: /linux1-vip/192.168.1.200/255.255.255.0/eth0:eth1

GSD exists.

ONS daemon exists.

Listener exists.

10显示 ASM 实例的配置

$ srvctl config asm -n linux1

+ASM1 /u01/app/oracle/product/10.2.0/db_1

11、查看集群中所有正在运行的实例

SELECT inst_id,

instance_number inst_no,

instance_name inst_name, 

parallel,status,database_status db_status,

active_state state, host_name host

FROM gv$instance

ORDER BY inst_id;

 

INST_ID INST_NO INST_NAME PAR STATUS DB_STATUS STATE HOST

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

1 1 orcl1 YES OPEN ACTIVE NORMAL rac1

2 2 orcl2 YES OPEN ACTIVE NORMAL rac2

 

12、查看位于磁盘组中的所有数据文件

select name from v$datafile

union

select member from v$logfile

union

select name from v$controlfile

union

select name from v$tempfile;

 

NAME

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

+FLASH_RECOVERY_AREA/orcl/controlfile/current.258.570913191

+FLASH_RECOVERY_AREA/orcl/onlinelog/group_1.257.570913201

+FLASH_RECOVERY_AREA/orcl/onlinelog/group_2.256.570913211

+FLASH_RECOVERY_AREA/orcl/onlinelog/group_3.259.570918285

+FLASH_RECOVERY_AREA/orcl/onlinelog/group_4.260.570918295

+ORCL_DATA1/orcl/controlfile/current.259.570913189

+ORCL_DATA1/orcl/datafile/example.257.570913311

+ORCL_DATA1/orcl/datafile/indx.270.570920045

+ORCL_DATA1/orcl/datafile/sysaux.260.570913287

+ORCL_DATA1/orcl/datafile/undotbs1.271.570920865

+ORCL_DATA1/orcl/datafile/undotbs2.265.570913331

+ORCL_DATA1/orcl/datafile/undotbs2.272.570921065

+ORCL_DATA1/orcl/onlinelog/group_3.266.570918279

+ORCL_DATA1/orcl/onlinelog/group_4.267.570918289

+ORCL_DATA1/orcl/tempfile/temp.258.570913303

 

21 rows selected.

13、查看属于“ORCL_DATA1”磁盘组的所有 ASM 磁盘

SELECT path

FROM v$asm_disk

WHERE group_number IN (select group_number

from v$asm_diskgroup

where name = 'ORCL_DATA1');

 

PATH

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

ORCL:VOL1

ORCL:VOL2

14启动/停止RAC集群

确保是以 oracle UNIX 用户登录的。我们将从rac1节点运行所有命令:

# su – oracle

$ hostname

Rac1

15停止 Oracle RAC 10g 环境

第一步是停止 Oracle 实例。当此实例(和相关服务)关闭后,关闭 ASM 实例。最后,关闭节点应用程序(虚拟 IPGSDTNS 监听器和 ONS)。

$ export ORACLE_SID=orcl1

$ emctl stop dbconsole

$ srvctl stop instance -d orcl -i orcl1

$ srvctl stop asm -n rac1

$ srvctl stop nodeapps –n rac1

16启动 Oracle RAC 10g 环境

第一步是启动节点应用程序(虚拟 IPGSDTNS 监听器和 ONS)。当成功启动节点应用程序后,启动 ASM 实例。最后,启动 Oracle 实例(和相关服务)以及企业管理器数据库控制台。

$ export ORACLE_SID=orcl1

$ srvctl start nodeapps -n rac1

$ srvctl start asm -n rac1

$ srvctl start instance -d orcl -i orcl1

$ emctl start dbconsole

17使用 SRVCTL 启动/停止所有实例

启动/停止所有实例及其启用的服务。我只是觉得有意思就把此步骤作为关闭所有实例的一种方法加进来了!

$ srvctl start database -d orcl

$ srvctl stop database -d orcl

 

18RAC crs自动启动脚本

with /etc/init.d/init.crs disable/enable to disable or enable it next time reboot

/etc/init.d/init.crsd
/etc/init.d/init.evmd
/etc/init.d/init.cssd

19RAC 中数据库启动/关闭/查看脚本

启动数据库:srvctl start database -d RACDB

关闭数据库:srvctl stop database -d RACDB

检查数据启动状态:srvctl status database -d RACDB

 

查看数据库实例状态:srvctl status instance -d RACDB -i RACDB1,RACDB2

 

20、单独启动节点的资源

srvctl start nodeapps -n gnd-rac01

srvctl start nodeapps -n ons-rac01

 

 

 

21RAC中客户端TNSNAME.ORA配置

# TNSNAMES.ORA Network Configuration File: D:\oracle\ora92\NETWORK\ADMIN\tnsnames.ora

# Generated by Oracle configuration tools.

 

HIS =

    )

    (CONNECT_DATA =

      (SID = ORCL1)

    )
