Oracle database connectivity issue
oracle
Solution
Are you using the same tnsnames.ora file for your SQL*Plus that your SQL Developer is using?
Also try adding `SQL_AUTHENTICATION_SERVICES = (NONE)` to your sqlnet.ora file.
Problem
I have a oracle database instance on my local machine , which i try to connect to . Using SQL Developer , i can connect to it . But when i use sqlplus i cannot connect to the instance. The error message i get is ``` ORA-28547:connection to server failed,probable oracle net admin error. ``` I tried restarting my TNS service but still the issue persists. And i need to connect to sqlplus because i need to import the dumps using ``` impdp system/***** schemas=abcd dumpfile=DUMP_500.dmp ``` Please let me know what other information is needed , so that i can post Thanks
