rac asm中密码文件的拷贝
检查主库节点1的dbs下没有密码文件，所以需先从asm中拷贝出来：
/oracle/app/oracle/product/19c/dbhome_1/dbs/
注意密码文件格式orapwcisdb1
从主库节点1拷贝密码文件到备库节点1的db home的dbs目录下：

再拷贝一份到备库节点2：
scp /oracle/app/oracle/product/19c/dbhome_1/dbs/orapwcisdb1 dgrac1:/oracle/app/oracle/product/19c/dbhome_1/dbs/orapwcisdb2
注意：如果密码文件没有，或格式不对，那么测试联通性的时候报错如下：
[[email protected] dbs]$ sqlplus sys/[email protected] as sysdba

在备库节点1使用oracle用户操作:
[[email protected] ~]$ srvctl add database -db cisdbdg -dbname cisdb -oraclehome /oracle/app/oracle/product/19c/dbhome_1 -dbtype RAC -role PHYSICAL_STANDBY
[[email protected] ~]$
[[email protected] ~]$ srvctl add instance -db cisdbdg -instance cisdb1 -node dgrac1
[[email protected] ~]$ srvctl add instance -db cisdbdg -instance cisdb2 -node dgrac2
[[email protected] ~]$ srvctl modify database -db cisdbdg -spfile '+data/cisdb/PARAMETERFILE/spfile.274.1024752989' -pwfile '+data/cisdb/password/orapwcisdb'
[[email protected] ~]$ srvctl modify database -db cisdb -diskgroup DATA
如果多个磁盘组，用逗号隔开。
