6.3、重启测试

重启节点2之后，在节点1查看状态，此时实例为ORACLE_2，运行于节点2上。grid@node1:~> crsctl stat res -t--------------------------------------------------------------------------------NAME TARGET STATE SERVER STATE_DETAILS --------------------------------------------------------------------------------Local Resources--------------------------------------------------------------------------------ora.DATA.dg ONLINE ONLINE node1 ONLINE OFFLINE node2 ora.FRA.dg ONLINE ONLINE node1 ONLINE OFFLINE node2 ora.LISTENER.lsnr ONLINE ONLINE node1 ONLINE ONLINE node2 ora.OCR_VOTE.dg ONLINE ONLINE node1 ONLINE OFFLINE node2 ora.asm ONLINE ONLINE node1 Started ONLINE ONLINE node2 Started ora.gsd OFFLINEOFFLINE node1 OFFLINEOFFLINE node2 ora.net1.network ONLINE ONLINE node1 ONLINE ONLINE node2 ora.ons ONLINE ONLINE node1 ONLINE ONLINE node2 ora.registry.acfs ONLINE ONLINE node1 ONLINE OFFLINE node2 --------------------------------------------------------------------------------Cluster Resources--------------------------------------------------------------------------------ora.LISTENER_SCAN1.lsnr 1 ONLINE OFFLINE STARTING ora.cvu 1 ONLINE ONLINE node1 ora.node1.vip 1 ONLINE ONLINE node1 ora.node2.vip 1 ONLINE ONLINE node2 ora.oc4j 1 ONLINE OFFLINE STARTING ora.oracle.db 2 ONLINE OFFLINE Instance Shutdown,S TARTING ora.oracle.oracleser.svc 1 ONLINE OFFLINE ora.scan1.vip 1 ONLINE ONLINE node1 grid@node1:~> srvctl status database -d ORACLE再次查看grid@node1:~> srvctl status database -d ORACLEInstance ORACLE_2 is running on node node1Online relocation: INACTIVEgrid@node1:~> crsctl stat res -t--------------------------------------------------------------------------------NAME TARGET STATE SERVER STATE_DETAILS --------------------------------------------------------------------------------Local Resources--------------------------------------------------------------------------------ora.DATA.dg ONLINE ONLINE node1 ora.FRA.dg ONLINE ONLINE node1 ora.LISTENER.lsnr ONLINE ONLINE node1 ora.OCR_VOTE.dg ONLINE ONLINE node1 ora.asm ONLINE ONLINE node1 Started ora.gsd OFFLINEOFFLINE node1 ora.net1.network ONLINE ONLINE node1 ora.ons ONLINE ONLINE node1 ora.registry.acfs ONLINE ONLINE node1 --------------------------------------------------------------------------------Cluster Resources--------------------------------------------------------------------------------ora.LISTENER_SCAN1.lsnr 1 ONLINE ONLINE node1 ora.cvu 1 ONLINE ONLINE node1 ora.node1.vip 1 ONLINE ONLINE node1 ora.node2.vip 1 ONLINE INTERMEDIATE node1 FAILED OVER ora.oc4j 1 ONLINE ONLINE node1 ora.oracle.db 2 ONLINE ONLINE node1 Open ora.oracle.oracleser.svc 1 ONLINE ONLINE node1 ora.scan1.vip 1 ONLINE ONLINE node1 grid@node1:~> 再次查看grid@node1:~> crsctl stat res -t--------------------------------------------------------------------------------NAME TARGET STATE SERVER STATE_DETAILS --------------------------------------------------------------------------------Local Resources--------------------------------------------------------------------------------ora.DATA.dg ONLINE ONLINE node1 ONLINE ONLINE node2 ora.FRA.dg ONLINE ONLINE node1 ONLINE ONLINE node2 ora.LISTENER.lsnr ONLINE ONLINE node1 ONLINE ONLINE node2 ora.OCR_VOTE.dg ONLINE ONLINE node1 ONLINE ONLINE node2 ora.asm ONLINE ONLINE node1 Started ONLINE ONLINE node2 Started ora.gsd OFFLINEOFFLINE node1 OFFLINEOFFLINE node2 ora.net1.network ONLINE ONLINE node1 ONLINE ONLINE node2 ora.ons ONLINE ONLINE node1 ONLINE ONLINE node2 ora.registry.acfs ONLINE ONLINE node1 ONLINE ONLINE node2 --------------------------------------------------------------------------------Cluster Resources--------------------------------------------------------------------------------ora.LISTENER_SCAN1.lsnr 1 ONLINE ONLINE node1 ora.cvu 1 ONLINE ONLINE node1 ora.node1.vip 1 ONLINE ONLINE node1 ora.node2.vip 1 ONLINE ONLINE node2 ora.oc4j 1 ONLINE ONLINE node1 ora.oracle.db 2 ONLINE ONLINE node1 Open ora.oracle.oracleser.svc 1 ONLINE ONLINE node1 ora.scan1.vip 1 ONLINE ONLINE node1 grid@node1:~> 重启节点2后，ORACLE_2实例切换至节点1运行，实例仍为ORACLE_2。
