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
SQL*Plus: Release 19.0.0.0.0 - Production on Wed Dec 30 16:46:51 2020

SQL> show parameter cluster
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
cdb_cluster boolean FALSE
cdb_cluster_name string
cluster_database boolean TRUE

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
