Oracle RAC数据库单节点轮流重启

0、sqlplus / as sysdba

备份参数文件 create pfile='/home/oracle/pfile.ora' from spfile;

备份控制文件 Alter database backup controlfile to trace;

1、关闭两节点的监听；

2、操作系统层面kill掉所有LOCAL=NO的所有进程，即：连接会话。

ps -ef | grep ucdb |grep LOCAL=NO | grep -v grep | awk '{print $2}' | xargs kill -9

3、关闭节点1

sqlplus / as sysdba

shutdown immediate;

tail -500f alertucdb.log;

4、起动节点1

sqlplus / as sysdba

startup;

tail -500f alertucdb.log

5、等待5-10分钟

6、关闭节点2

sqlplus / as sysdba

shutdown immediate;

tail -500f alertucdb.log;

7、起动节点2

sqlplus / as sysdba

startup;

tail -500f alertucdb.log;
