oracle services 启动会将对应pdb带起来（反之不会） ，mount下只有pdb default 会启动

[oracle@rac3 admin]$ srvctl add service -d cdb -s pdb1_srv -pdb pdb1 -r rac1,rac2,rac3
PRKO-2101 : Failed to find database instances rac1,rac2,rac3
[oracle@rac3 admin]$ srvctl add service -d cdb -s pdb1_srv -pdb pdb1 -r cdb1,cdb2,cdb3
[oracle@rac3 admin]$ srvctl start service -s pdb1_srv -d cdb

srvctl start service -d cdb -role
