ORA-12541: TNS There is no listener

by stergios_nik . Updated 25 years, 5 months ago

Hello,

I have just installed my ORACLE 8i, on a server with the following characteristics Pentium III 800 Mhz, 512MB.

On the server when I execute the OraHome->Application Development->SQL plus tool, I get connected to the database.

The problem is to do with the client software.

I installed the Oracle client on a win95 PC (windows socket 2 installed), but when I performed the database connection testing I get the following error:
“ORA-12541: TNS, there is not listener”

I checkedthe service on my NT 4 server concerning TNS listener and I saw that it was up and running. I noticed that some oracle services were stopped so I started them hopping that this will solve the problem but it did not work!

Also, I checked whether ORACLE server can be pinged and I got replies….thus the network seems to work OK!

Please, If you have any idea what is going wrong, please help. I think something is going wrong with the server)
