The port number running for oracle and database service name may not be correct. Just go to command prompt and search for the correct one. go through these steps:
open cmd prompt
search for lsnrctl services
it will show the port number and service name running for oracle
I am seeing this, looks like port is 1521, but no listener. please let me know how can I resolve this issue.
The TNS-12541 message reads, “TNS no listener.” This happens if the listener is either down as it attempts to make a connection or if it has not been started or improperly configured. In addition, it may be caused by a connectivity problem with the network.
First, make sure that the listener is up and running. To do this, go to the Control Panel into Services under NT or listener control program.
I decided to go with 11g Express edition as 18c XE gives me trouble after trouble, can not waste more time. Hope that using 11g Express Edition OK work well with what is taught here. Please let me know otherwiese.
