19c srvctl添加资源报错ORA-12547

问题现象：
srvctl start 方式启动数据库后
sqlplus / as sysdba 登录报错ORA-12547

相关文章：https://blog.dbi-services.com/after-startup-database-with-srvctl-sqlplus-as-sysdba-results-in-ora-12547-tnslost-contact/
MOS：DB started by sqlplus cannot be stopped by srvctl( ORA-12547 ), and vice versa (Doc ID 2612663.1)

1、验证问题

su - oracle
srvctl config database -d racdg

应该会发现 ORACLE_HOME  的 db_1 后面带着 / 

2、解决问题

srvctl modify database -d racdg -oraclehome /u02/app/oracle/product/19.9.0/db_1
srvctl stop database -d racdg
srvctl start database -d racdg

sqlplus / as sysdba  验证即可
