Ive recently installed Oracle 10g on my Windows XP and was able to connect. When i did a shutdown immediate and tried to connect again as a sysdba i get an error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Did a few basic checks like Oracle services, listener and all seems up and running. As im studyin Oracle 10g currently, please explain me in simple language meand guide to what i should do to resolve this problem. Any help is much appreciated!
