Cannot connect to database hosted at CentOS VM through SQL Developer on Windows
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I've installed Oracle 12c smoothly today and was able to start lsnrctl and database.
SQL*Plus connection is okay inside VM.
I've set the IP address to be static @ 192.168.0.20 (CentOS VM).
I am able to ping the VM address from Windows but I cannot connect to the database through SQL Developer inside Windows. This is the error I got:
The network adapter is unable to establish the connection
I suspect it may be a firewall problem? But I have opened port 1521 using firewall-cmd.

Are you sure its port 1521? Are you using Grid Infrastructure? If so you might have created separate listener for Oracle Database.

try to setting listener, for example
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.20)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
tnsname
DBORACLE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.20)(PORT = 2001))
(CONNECT_DATA =
