一、fk数据库

1、关闭监听

lsnrctl stop

2、备份参数文件

SQL> create pfile='/tmp/initfk.ora' from spfile;

3、修改数据库集群参数

oracle@EPC1-C3:/home/oracle$ export ORACLE_SID=fk1

oracle@EPC1-C3:/home/oracle$ sqlplus / as sysdba

4、停止两节点数据库实例,打开节点1实例

#srvctl stop database -d fk

#srvctl start database -d fk -i fk1 -o mount

5、创建、配置归档路径并开启归档路径，将集群参数修改至原值

oracle@EPC1-C3:/home/oracle$ sqlplus / as sysdba
