Hi everyone, it's my first time configuring a VM with Oracle Linux and Oracle 18.3 on it.
Everything was going ok, but I'm having some trouble to connect to my PDBs.
I can connect to my main container using SQL Developer from a client machine, but can't connect to the pdbs...
The pdbs are open, and I can alter session to get into them, I just can't connect to them directly...
I have been going back and forth and trying many things for a few days now, and just can't find a way to connect to them.
Any help is truly appreciated.

They seem to be up and running...
SQL> show pdbs

CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 ORCLPDB READ WRITE NO
4 PDBTS READ WRITE NO

My listener is never with status READY, always UNKNOWN...
Services Summary...

The command completed successfully

And here is my Listener...

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1539))

)


I can connect using SQL Developer to the ORCL root container, but just can't manage to connect to the pdbs
