How can I detach domain name from PDB Service?

in Database Install/Upgrade/Opatch (MOSC) 8 commentsAnswered

I am in the process of upgrading our Ebiz 12.1.3 to 19c (v8). Upgrade went smoothly and I was able to bring up both 19c database and Application services normally. At the end, I had to bounce the database after modifying the init parameters . When the database back online, I was unable to connect our PDB database using 'sqlplus system/xxxxx@psmp' which is returning error:

ERROR:

ORA-12521: TNS:listener does not currently know of instance requested in connect descriptor


Observation:

I have a Pluggable Database (PDB) with a simple service name (psmp). When the service name is registered with our listener, our domain name is automatically appended to our service name. This is what causing the error.

Howdy, Stranger!
