一.巡检RAC数据库
1.1列出数据库
[grid@node1 ~]$ srvctl config database racdb [grid@node1 ~]$
1.2列出数据库的实例
[grid@node1 ~]$ srvctl status database -d racdb Instance racdb1 is running on node node1 Instance racdb2 is running on node node2
1.3数据库的配置
[grid@node1 ~]$ srvctl config database -d racdb -a Database unique name: racdb Database name: racdb Oracle home: /u01/app/oracle/11.2.0/dbhome_1 Oracle user: oracle Spfile: +DATA/racdb/spfileracdb.ora Domain: Start options: open Stop options: immediate Database role: PRIMARY Management policy: AUTOMATIC Server pools: racdb Database instances: racdb1,racdb2 Disk Groups: DATA Services: Database is enabled Database is administrator managed [grid@node1 ~]$
二.巡检Grid
2.1集群名称
[grid@node1 ~]$ cemutlo -n scan-cluster [grid@node1 ~]$
2.2检查集群栈状态
[grid@node1 ~]$ crsctl check cluster -all ************************************************************** node1: CRS-4537: Cluster Ready Services is online CRS-4529: Cluster Synchronization Services is online CRS-4533: Event Manager is online ************************************************************** node2: CRS-4537: Cluster Ready Services is online CRS-4529: Cluster Synchronization Services is online CRS-4533: Event Manager is online ************************************************************** [grid@node1 ~]$
2.3 集群的资源
[grid@node1 ~]$ crsctl status res -t

2.4检查节点应用
[grid@node1 ~]$ srvctl status nodeapps VIP node1-vip is enabled VIP node1-vip is running on node: node1 VIP node2-vip is enabled VIP node2-vip is running on node: node2 Network is enabled Network is running on node: node1 Network is running on node: node2 GSD is disabled GSD is not running on node: node1 GSD is not running on node: node2 ONS is enabled ONS daemon is running on node: node1 ONS daemon is running on node: node2 eONS is enabled eONS daemon is running on node: node1 eONS daemon is running on node: node2 [grid@node1 ~]$
2.5 检查SCAN
检查scan-ip地址的配置 [grid@node1 ~]$ srvctl config scan SCAN name: scan-cluster.com, Network: 1/192.168.0.0/255.255.255.0/eth0 SCAN VIP name: scan1, IP: /scan-cluster/192.168.0.24 SCAN VIP name: scan2, IP: /scan-cluster/192.168.0.25 SCAN VIP name: scan3, IP: /scan-cluster/192.168.0.26 [grid@node1 ~]$ 检查scan-ip地址的实际分布及状态 [grid@node1 ~]$ srvctl status scan SCAN VIP scan1 is enabled SCAN VIP scan1 is running on node node2 SCAN VIP scan2 is enabled SCAN VIP scan2 is running on node node1 SCAN VIP scan3 is enabled SCAN VIP scan3 is running on node node1 [grid@node1 ~]$ 检查scan监听配置 [grid@node1 ~]$ srvctl config scan_listener SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521 SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1521 SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1521 [grid@node1 ~]$ 检查scan监听状态 [grid@node1 ~]$ srvctl status scan_listener SCAN Listener LISTENER_SCAN1 is enabled SCAN listener LISTENER_SCAN1 is running on node node2 SCAN Listener LISTENER_SCAN2 is enabled SCAN listener LISTENER_SCAN2 is running on node node1 SCAN Listener LISTENER_SCAN3 is enabled SCAN listener LISTENER_SCAN3 is running on node node1 [grid@node1 ~]$
2.6 检查VIP和监听

[grid@node1 ~]$ 检查磁盘组 [grid@node1 ~]$ srvctl status diskgroup -g DATA Disk Group DATA is running on node1,node2 [grid@node1 ~]$ 查看ASM磁盘 [root@node1 bin]# oracleasm listdisks VOL1 VOL2 [root@node1 bin]# 查看物理磁盘与asm 磁盘对应关系 [root@node1 bin]# oracleasm querydisk -v -p VOL1 Disk "VOL1" is a valid ASM disk /dev/sdb1: LABEL="VOL1" TYPE="oracleasm" [root@node1 bin]#
2.8检查集群节点间的时钟同步
检查节点node1的时间同步 [grid@node1 ~]$ cluvfy comp clocksync -verbose ....... Verification of Clock Synchronization across the cluster nodes was successful. [grid@node1 ~]$
检查节点node2的时间同步 [grid@node2 ~]$ cluvfy comp clocksync -verbose .............. CTSS is in Active state. Proceeding with check of clock time offsets on all nodes... Reference Time Offset Limit: 1000.0 msecs Check: Reference Time Offset Node Name Time Offset Status ------------ ------------------------ ------------------------ node2 -89900.0 failed Result: PRVF-9661 : Time offset is NOT within the specified limits on the following nodes: "[node2]" PRVF-9652 : Cluster Time Synchronization Services check failed Verification of Clock Synchronization across the cluster nodes was unsuccessful on all the specified nodes. [grid@node2 ~]$
注：节点2的服务器时间出现问题
至此，对Grid的巡检基本上就算完成了
