UDI-12154: operation generated ORACLE error 12154 ORA-12154: TNS:could not resolve the connect identifier specified
需要使用：
select name,pdb from v$services;
获取一下查询结果如下：
NAME ---------------------------------------------------------------- PDB -------------------------------------------------------------------------------- orclXDB CDB$ROOT orcl CDB$ROOT SYS$BACKGROUND CDB$ROOT NAME ---------------------------------------------------------------- PDB -------------------------------------------------------------------------------- SYS$USERS CDB$ROOT orclpdb ORCLPDB
注意这个：
orclpdb ORCLPDB
然后查看tnsnames.ora
