Default Listener "LISTENER" is not configured in Grid Infrantructure home.Use NetCA to configure Default Listener and return DBCA
因为oracle 11g rac在安装过程中会自动创建监听，无需手动创建，首先使用grid用户登录查看监听状态：
[grid@node1 ~]$ crs_stat -t Name Type Target State Host ------------------------------------------------------------ ora.DATA.dg ora....up.type ONLINE ONLINE node1 ora....N1.lsnr ora....er.type ONLINE ONLINE node1 ora.OCRVOTE.dg ora....up.type ONLINE ONLINE node1 ora.asm ora.asm.type ONLINE ONLINE node1 ora.cvu ora.cvu.type ONLINE ONLINE node1 ora.gsd ora.gsd.type OFFLINE OFFLINE ora....network ora....rk.type ONLINE ONLINE node1 ora....SM1.asm application ONLINE ONLINE node1 ora.node1.gsd application OFFLINE OFFLINE ora.node1.ons application ONLINE ONLINE node1 ora.node1.vip ora....t1.type ONLINE ONLINE node1 ora....SM2.asm application ONLINE ONLINE node2 ora.node2.gsd application OFFLINE OFFLINE ora.node2.ons application ONLINE ONLINE node2 ora.node2.vip ora....t1.type ONLINE ONLINE node2 ora.oc4j ora.oc4j.type ONLINE ONLINE node1 ora.ons ora.ons.type ONLINE ONLINE node1 ora.scan1.vip ora....ip.type ONLINE ONLINE node1
使用命令crs_stat -t查看各资源状态,发现没有监听资源，下面查看详细信息：
[grid@node1 ~]$ crs_stat NAME=ora.DATA.dg TYPE=ora.diskgroup.type TARGET=ONLINE STATE=ONLINE on node1 NAME=ora.LISTENER_SCAN1.lsnr TYPE=ora.scan_listener.type TARGET=ONLINE STATE=ONLINE on node1 NAME=ora.OCRVOTE.dg TYPE=ora.diskgroup.type TARGET=ONLINE STATE=ONLINE on node1 NAME=ora.asm TYPE=ora.asm.type TARGET=ONLINE STATE=ONLINE on node1 NAME=ora.cvu TYPE=ora.cvu.type TARGET=ONLINE STATE=ONLINE on node1 NAME=ora.gsd TYPE=ora.gsd.type TARGET=OFFLINE STATE=OFFLINE NAME=ora.net1.network TYPE=ora.network.type TARGET=ONLINE STATE=ONLINE on node1 NAME=ora.node1.ASM1.asm TYPE=application TARGET=ONLINE STATE=ONLINE on node1 NAME=ora.node1.gsd TYPE=application TARGET=OFFLINE STATE=OFFLINE NAME=ora.node1.ons TYPE=application TARGET=ONLINE STATE=ONLINE on node1 NAME=ora.node1.vip TYPE=ora.cluster_vip_net1.type TARGET=ONLINE STATE=ONLINE on node1 NAME=ora.node2.ASM2.asm TYPE=application TARGET=ONLINE STATE=ONLINE on node2 NAME=ora.node2.gsd TYPE=application TARGET=OFFLINE STATE=OFFLINE NAME=ora.node2.ons TYPE=application TARGET=ONLINE STATE=ONLINE on node2 NAME=ora.node2.vip TYPE=ora.cluster_vip_net1.type TARGET=ONLINE STATE=ONLINE on node2 NAME=ora.oc4j TYPE=ora.oc4j.type TARGET=ONLINE STATE=ONLINE on node1 NAME=ora.ons TYPE=ora.ons.type TARGET=ONLINE STATE=ONLINE on node1 NAME=ora.scan1.vip TYPE=ora.scan_vip.type TARGET=ONLINE STATE=ONLINE on node1
手动添加监听资源：
