I created a common user and granted a session creating permission and properly set the TNS record on TNS ora file for plugable database but when i am trying to login to a pluggable database using a common or local user get following error
ORA-12514 TNS:listener does not currently know of service requested in connect descriptor.
I am using Oracle 18C but I am not getting errors when i log in with the SYS or SYSTEM account
Could you please let me know, if anyone knows the reason behind this error?
