Cannot connect to PDB
Hi,
On 19 c on AIX
cannot connect to PDB:
sqlplus system@PDB
Enter password:
ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified
But connected to cdb I have:
SQL> SELECT name, open_mode from v$pdbs;
NAME OPEN_MODE
-------------------- ------------------------------
PDB$SEED READ ONLY
PDB READ WRITE
And:
tnsping PDB
Used parameter files:
/sqlnet.ora
TNS-03505: Failed to resolve name
I tried also:
sqlplus system@hostname/PDB
ORA-12154: TNS:could not resolve the connect identifier specified
Thanks.
