　　 crsctl 检查crs

　　crsctl check crs 检查crs状态

　　crsctl start crs 启动crs

　　crsctl stop crs

　　crsctl check crsd

　　crs_stat t

　　等等其 /etc/init d/init crs stop /etc/init d/init crsd stop 等开机启动service 脚本如果

　　如果你发现crs不能正常工作可以检查调试一下这些脚本检查一下进程是不是这个脚本可以正常工作

　　crs的启动log 在 $ORA_CRS_HOME/log $ORA_CRS_HOME/log/client 下面可以找到出现错误可以检查一下对应的log

　　 srvctl 启动数据库与实例

　　srvctl start database d NEWRAC 启动名字为NEWRAC的数据库

　　查看当前数据库的状态

　　[root@newrac ~]# srvctl status database d NEWRAC

　　Instance NEWRAC is running on node newrac

　　Day to day management of Oracle G RAC

　　CRS management

　　rnCRSCTL mand control of the CRS Services local node (Oracle clusterware processes)

　　rn stop CRS:

　　rn $ crsctl stop crs or

　　rn $ / etc / init crs stop or

　　rn $ crs_stop all

　　rn start CRS:

　　rn $ crsctl start crs or

　　rn $ / etc / init crs start

　　rn prohibited Clusterware restart automatically at system startup methods:

　　rn $ / etc / init crs disable

　　rn start Clusterware restart automatically at system startup methods:

　　rn $ / etc / init crs enable

　　rn view the status CRS Services

　　rn $ crsctl check crs

　　rnOCR resource management

　　rnOCR resources when the RAC cluster up and running successfully you can use the instrument crs_stat see the following:

　　rn $ ORA_CRS_HOME / bin / crs_stat

　　rn general the status of all resources should be online In addition OCR will be four hours each to back up first Have some cases you can restore the OCR configuration file to restore problems OCR

　　rn such as the use of the following situations occur:

　　rn $ crs_stat t

　　rnCRS : Cannot municate with the CRS daemon

　　rn $ crsctl check boot

　　rnFailure at procr_open_key with status

　　rnPROC : The cluster registry key to be operated on does not exist

　　rn $ crsctl check crs

　　rnFailure contacting CSS daemon

　　rnCannot municate with CRS

　　rnCannot municate with EVM

　　rn caused this error may be due to a lost OCR configuration We can use this backup to restore the previous configuration

　　rn # / etc / init crs disable

　　rn # / etc / init crs stop

　　rn before the crs process to ensure that all stopped

　　rn # su oracle

　　rn $ cd $ ORA_CRS_HOME / bin

　　rn $ / ocrconfig restore / opt / app / oracle / crs / cdata / crs / week ocr

　　rn then switch to the root user the re enable CRS

　　rn # / etc / init crs enable

　　Finally reboot both node rn

　　Introduction rnSRVCTL order

　　rnSRVCTL order to control the RAC database instance listener as well as services

　　rn at SRVCTL usually carried out under ORACLE user Us to introduce the following mand srvctl

　　rn through SRVCTL mand to start / stop / check all of the examples:

　　rn $ srvctl start | stop | status database d

　　rn start / stop the specified instance:

　　rn $ srvctl start | stop | status instance d i

　　rn list all of the current RAC

　　rn $ srvctl config database d

　　rn start / stop / check all nodeapps such as: VIP GSD listener ONS:

　　rn $ srvctl start | stop | status nodeapps n

　　rn if you use ASM srvctl can also start / stop ASM instance:

　　rn $ srvctl start | stop asm n [ i] [ o]

　　rn access to all environmental information:

　　rn $ srvctl getenv database d [ i]

　　rn set the overall environment and the variables:

　　rn $ srvctl setenv database d t LANG = en

　　rn have been deleted from the OCR databases:

　　rn $ srvctl remove database d

　　rn to the OCR to add a database:

　　rn $ srvctl add database d o

　　rn [ m] [ p] [ A / netmask] [ r (PRIMARY | PHYSICAL_STANDBY | LOGICAL_STANDBY)] [ s]

　　rn to the OCR to add a database instance:

　　rn $ srvctl add instance d i n

　　rn to the OCR Add a ASM instance:

　　rn $ srvctl add asm n i o

　　rn add a service

　　rn $ srvctl add service d s r [ a] [ P] [ u]

　　rn modified on other nodes in the service

　　rn $ srvctl modify service d s I t

　　rn relocate a service node to other nodes

　　rnsrvctl relocate service d s I

　　and related services rnCRS mon mand demo

　　rn view order status

　　rn # su oracle to switch to the oracle user

　　rn $ crs_stat t check crs and all of the service status

　　rn $ crsctl check crs use crsctl order to check the status of related services crs

　　rn $ srvctl status nodeapps n db (db ) use srvctl to view the services on all nodes and whether it is normal

　　rn $ srvctl status database d db the database using srvctl status view

　　rn turn off start up and related services in order

　　rn # su oracle

　　rn $ crs_start all start all crs Service

　　rn $ crs_stop all to stop all of the Services crs

　　rn $ crsctl start crs Services start crs

　　rn $ crsctl stop crs stop crs Service

　　rn $ srvctl start nodeapps n db (db ) Start a node on the application of all

　　rn $ srvctl stop nodeapps n db (db ) stop a node on the application of all

　　rn $ srvctl start listener n db (db ) Start a node listener

　　rn $ srvctl stop listener n db (db ) The listener to stop a node

　　RAC mon mand description 原文地址

　　oracle rac database of monly used mands:

　　 The state of all instances and services

　　srvclt status database d orcl

　　A single instance of state:

　　srvctl status instance d orcl i orcl /orcl

　　Global names in the database status of the service:

　　srvctl status service d orcl s orcltest

　　Application specific node state:

　　srvctl status nodeapps n linux

　　ASM instance state

　　srvctl status asm n linux

　　Lists all database configuration:

　　srvctl config database

　　Display RAC database configuration information:

　　srvctl config database d orcl

　　Show all services specified cluster database

　　srvctl config service d orcl

　　Display node application configuration information (VIP GSD ONS Listener etc )

　　srvctl config nodeapps n linux a g s l

　　Shows the configuration of ASM instance

　　srvctl config asm n linux

　　Cluster all running instances:

　　select

　　inst_id instance_number inst_no instance_name is inst_name

　　parallel status database_status db_status

　　active_state state host_name host from gv $ instance

　　order by inst_id;

　　In the disk group all data files:

　　select name from v $ datafile

　　union

　　select member from v $ logfile

　　union

　　select name from v $ controlfile

　　union

　　select name from v $ tempfile;

　　Start and stop RAC databases:

　　su oracle

　　hostname

　　Stop oracle rac g environment:

　　The first step: stop oracle instance when this instance (and related services) closed shut down ASM instances and finally close the node applications (Virtual IP GSD TNS Listener and ONS)

　　export oracle_sid = orcl

　　emctl stop dbconsole

　　srvclt stop instance d orcl i orcl

　　srvctl stop asm n rac

　　srvctl stop nodeapps n rac

　　Start RAC environment:

　　The first step is to start the node applications (Virtual IP GSD TNS listener and ONS

　　) When the successful launch of the node application start the ASM instance and finally start the ORACLE instance (and related services) and Enterprise Manager Database console

　　export oracle_sid = orcl

　　srvctl start nodeapps n rac

　　srvctl start asm n rac

　　srvctl start instance d orcl i orcl

　　emctl start dbconsole

　　Practical srvclt start to stop all instances of:

　　srvclt start database d orcl

　　srvctl stop database d orcl

　　Start stop the listener:

　　lsnrctl start listener_hostb

　　lsnrctl stop listener

　　Oracle G R RAC daily management

　　CRS management

　　CRSCTL mand controls the local node s CRS services (Oracle clusterware processes)

　　Stop CRS:

　　$ Crsctl stop crs or

　　$ / Etc / init crs stop or

　　$ Crs_stop all

　　Start CRS:

　　$ Crsctl start crs or

　　$ / Etc / init crs start

　　Prohibition Clusterware restart automatically after system start method:

　　$ / Etc / init crs disable

　　Start Clusterware automatically start after reboot the system approach:

　　$ / Etc / init crs enable

　　See CRS service status

　　$ Crsctl check crs

　　OCR resource management

　　OCR resources when the RAC cluster up and running after success you can use crs_stat tools see the following:

　　$ ORA_CRS_HOME / bin / crs_stat

　　Typically the state of all resources should be online In addition OCR will backup every hours once In some cases you can restore the OCR configuration file to restore the problem of OCR

　　Such as use of the following situations occur:

　　$ Crs_stat t

　　CRS : Cannot municate with the CRS daemon

　　$ Crsctl check boot

　　Failure at procr_open_key with status

　　PROC : The cluster registry key to be operated on does not exist

　　$ Crsctl check crs

　　Failure contacting CSS daemon

　　Cannot municate with CRS

　　Cannot municate with EVM

　　A possible cause of this error because the OCR configuration lost We can use this backup to restore the previous configuration

　　# / Etc / init crs disable

　　# / Etc / init crs stop

　　First ensure that all of the crs process all the stops

　　# Su oracle

　　$ Cd $ ORA_CRS_HOME / bin

　　$ / Ocrconfig restore / opt / app / oracle / crs / cdata / crs / week ocr

　　Then switch to the root user the re enable CRS

　　# / Etc / init crs enable

　　Finally reboot the o nodes

　　SRVCTL mand description

　　SRVCTL mand can control the RAC database instance listener and services

　　Usually SRVCTL executed in the ORACLE user Here s a srvctl mand

　　 by SRVCTL mand to start / stop / check all of the examples:

　　$ Srvctl start | stop | status database d <db_name>

　　 start / stop the specified instance:

　　$ Srvctl start | stop | status instance d <db_name> i <instance_name>

　　 lists all the current RAC under

　　$ Srvctl config database d <db_name>

　　 start / stop / check all the nodeapps such as: VIP GSD listener ONS:

　　$ Srvctl start | stop | status nodeapps n <node_name>

　　 if you use ASM srvctl can also start / stop ASM instance:

　　$ Srvctl start | stop asm n <node_name> [ i <asm_inst_name>] [ o <oracle_home>]

　　 can get all of the environmental information:

　　$ Srvctl getenv database d <db_name> [ i <instance_name>]

　　 set the global environment and the variables:

　　$ Srvctl setenv database d <db_name> t LANG = en

　　 to remove from the existing OCR databases:

　　$ Srvctl remove database d <db_name>

　　 add a database to OCR:

　　$ Srvctl add database d <db_name> o <oracle_home>

　　[ M <domain_name>] [ p <spfile>] [ A <name|ip> / netmask] [ r (PRIMARY | PHYSICAL_STANDBY | LOGICAL_STANDBY)] [ s <start_options>]

　　 to the OCR to add a database instance:

　　$ Srvctl add instance d <db_name> i <instance_name> n <node >

　　 to add an OCR ASM instance:

　　$ Srvctl add asm n <node_name> i <asm_inst_name> o <oracle_home>

　　 add a service

　　$ Srvctl add service d <db_name> s <service_name> r <preferred_list> [ a <available_list>] [ P <TAF_policy>] [ u]

　　 modify the service to other nodes

　　$ Srvctl modify service d <db_name> s <service_name> I <orig_instance_name> t <target_instance_name>

　　 relocate to a service node to other nodes

　　srvctl relocate service d <db_name> s <service_name> I

　　CRS and related services a demonstration of mon mands

　　 view the status of the mand

　　# Su oracle first switch to the oracle user

　　$ Crs_stat t View crs and all the service of the state

　　$ Crsctl check crs use crsctl mand to check the status of related services crs

　　$ Srvctl status nodeapps n db (db ) use the srvctl view the services on all nodes are normal

　　$ Srvctl status database d db the database using srvctl view the status of startup and shutdown mands related services
