TNS: could not resolve the connect identifier specified
I have a problem connecting to a database, but before someone tells me to check something or other,
I want to make clear:
The database is working well.
I can connect perfectly THROUGH: sqlplus / as sysdba directly from the server where it resides. The OS is Linux.
I can connect through Enterprise Manager (https: / / 172.22.170.198:1158 / em) too.
I can not do:
I can not connect THROUGH Toad
I can not connect from SQL Plus from my laptop.
I have other two databases on Linux in other servers, and I can connect perfectly well on any tool.
This DB, which is giving me problems when trying to connect through Toad or SQL Plus, I get the following message:
ORA-12154: TNS: could not resolve the connect identifier specified.
I repeat, the database is working fine, just that I want to connect from my laptop with these
tools (Toad and SQL plus) and gives me the error explain previously.
Anyone have any idea how I can solve this problem?
Thanks in advance.
