Oracle RAC的日常基本维护指令

oracle rac日常基本维护命令 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 单个实例的状态 $ srvctl status instance -d orcl -i orcl2 Instance orcl2 is running on node linux2 在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 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 ASM 实例的状态 $ srvctl status asm -n linux1 ASM instance +ASM1 is running on node linux1. 列出配置的所有数据库 $ srvctl config database orcl 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 显示指定集群数据库的所有服务 $ srvctl config service -d orcl orcltest PREF: orcl2 orcl1 AVAIL: 显示节点应用程序的配置 —（VIP、GSD、ONS、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. 显示 ASM 实例的配置 $ srvctl config asm -n linux1 +ASM1 /u01/app/oracle/product/10.2.0/db_1 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$instance ORDER BY inst_id; INST_ID INST_NO INST_NAME PAR STATUS DB_STATUS STATE HOST -------- -------- ---------- --- ------- ------------ --------- ------- 1 1 orcl1 YES OPEN ACTIVE NORMAL rac1 2 2 orcl2 YES OPEN ACTIVE NORMAL rac2 位于磁盘组中的所有数据文件 select name from v$datafile union select member from v$logfile union select name from v$controlfile union select name from v$tempfile; NAME ------------------------------------------- +FLASH_RECOVERY_AREA/orcl/controlfile/current.258.570913191 +FLASH_RECOVERY_AREA/orcl/onlinelog/group_1.257.570913201 +FLASH_RECOVERY_AREA/orcl/onlinelog/group_2.256.570913211 +FLASH_RECOVERY_AREA/orcl/onlinelog/group_3.259.570918285 +FLASH_RECOVERY_AREA/orcl/onlinelog/group_4.260.570918295 +ORCL_DATA1/orcl/controlfile/current.259.570913189 +ORCL_DATA1/orcl/datafile/example.257.570913311 +ORCL_DATA1/orcl/datafile/indx.270.570920045 +ORCL_DATA1/orcl/datafile/sysaux.260.570913287 +ORCL_DATA1/orcl/datafile/system.262.570913215 +ORCL_DATA1/orcl/datafile/undotbs1.261.570913263 +ORCL_DATA1/orcl/datafile/undotbs1.271.570920865 +ORCL_DATA1/orcl/datafile/undotbs2.265.570913331 +ORCL_DATA1/orcl/datafile/undotbs2.272.570921065 +ORCL_DATA1/orcl/datafile/users.264.570913355 +ORCL_DATA1/orcl/datafile/users.269.570919829 +ORCL_DATA1/orcl/onlinelog/group_1.256.570913195 +ORCL_DATA1/orcl/onlinelog/group_2.263.570913205 +ORCL_DATA1/orcl/onlinelog/group_3.266.570918279 +ORCL_DATA1/orcl/onlinelog/group_4.267.570918289 +ORCL_DATA1/orcl/tempfile/temp.258.570913303 21 rows selected. 属于“ORCL_DATA1”磁盘组的所有 ASM 磁盘 SELECT path FROM v$asm_disk WHERE group_number IN (select group_number from v$asm_diskgroup where name = 'ORCL_DATA1'); PATH ---------------------------------- ORCL:VOL1 ORCL:VOL2 　二： 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 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IP、GSD、TNS 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 启动 Oracle RAC 10g 环境 第一步是启动节点应用程序（虚拟 IP、GSD、TNS 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 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
