RAC监听日志：tnsname.ora

CRS日志：

位置：Oracle集群涉及的日志主要位于“$ORA_CRS_HOME/log”和“$ORACLE_HOME/log”目录中

目录结构：tree -d $ORA_CRS_HOME/log

tree -d $ORACLE_HOME/log

禁止Clusterware在系统重启后自动启动：/etc/init.d/init.crs disable

让Clusterware在系统重启后自动启动: /etc/init.d/init.crs enable

启动CRS;crsctl start crs

关闭CRS：crsctl stop crs

检查CRS状态：RAC1 AND RAC2: crsctl check crs

启动数据库：

$srvctl start nodeapps -n rac1

$srvctl start nodeapps -n rac2

$srvctl start asm -n rac1

$srvctl start asm -n rac2

$srvctl start instance -d racdb -i racdb1

$srvctl start instance -d racdb -i racdb2

格式：ora.hostname.ASM2.asm，节点1格式：ora.hostname.ASM1.asm)

Attempting to stop `ora.node2.ASM2.asm` on member `node2`

Stop of `ora.node2.ASM2.asm` on member `node2` succeeded.

node2-> crs_start ora.node2.ASM2.asm

Attempting to start `ora.node2.ASM2.asm` on member `node2`

Start of `ora.node2.ASM2.asm` on member `node2` succeeded.

2、--单独启动和关闭节点node2的gsd

crs_stop ora.node2.gsd   (格式：ora.hostname.gsd)

crs_start ora.node2.gsd

3、--单独启动和关闭节点node2的ons

crs_stop ora.node2.ons  (格式:ora.hostname.ons)

crs_start ora.node2.ons

4.单独启动vip

crs_stop ora.node2.vip(格式：ora.hostname.vip)

crs_start ora.node2.vip

5.单独启动实例(inst)

crs_stop  ora.racdb.racdb2.inst (格式：ora.db_name.instance_name.inst)

crs_start ora.racdb.racdb2.inst

6.单独启动监听(lsnr)

crs_stop ora.node1.LISTENER_NODE1.lsnr (格式：ora.hostname.listener_name.lsnr)

crs_start ora.node1.LISTENER_NODE1.lsnr
