Hi Shivanand Rao,Please note that you are responding to a message that is over a year old. Better to have started your own thread.
I have installed Oracle 11gR2 and tried to Un-install it, which i was not able to , so i have deleted all the services from the regedit.exe regarding Oracle .We don't really know what you did. Only what you describe. Error messages are much more meaningful when the are associated with the command that produced them. Copy and paste the entire command line session (full command and full result) is much more beneficial in resolving these kinds of issues.
now i tried to re-install Oracle and installed it successfully but when i am trying to connect to SQLPLUS and trying to connect to the database i am getting the error ORA-12543.
Below are the options i tried :
tried to ping TNSPING <listenername> and it is working.
still i dont understand why am i getting this error , please help .
Thanks in advance
