搭建ADG后，实例2无法启动 ORA-29760: instance_number parameter not specified

oerr ora 29760
29760, 00000, "instance_number parameter not specified"
// *Cause: The init.ora file did not contain a value for the instance_number
//         which is required to identify this instance to other instances of
//         the database running on the same cluster
// *Action: Assign a value to the instance_number parameter in the init.ora
//          parameter file

create pfile='/tmp/test.ora' from spfile;
cat /tmp/test.ora'
