Dear stackoverflow community,
I know this question was already asked, but I tried to find a solution and unfortunately I'm blocked since 3 days now.
I installed Oracle 12c in Linux centos 7 server. When I try to access to the Oracle DB with SQL developer I have the following error:
Listener refused the connection with following error: ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
What I do not understand is that if I restart the database I can connect. But Once I disconnect a try a reconnect I got the same error. Here is my listener.ora file
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = ns3008269.ip-151-80-45.eu)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
And my tnsnames.ora is :
rspdata =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = ns3008269.ip-151-80-45.eu)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = rspdata)
)
)
oraclepdb =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = ns3008269.ip-151-80-45.eu)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = oraclepdb)
)
)
And finally you can fin in attachment a screenshot of my Installation configuration.
I tried lot of and lot of thing... but still blocked.
