When trying to debug on an Oracle 12 RAC PDB (pluggable) database, the following error is returned.
"Cannot connect debug session. in order to debug when connected to a RAC instance, do one of the following:
1) Create entries for the individual RAC instances in your tnsnames.ora file.
2) Connect directly to an individual RAC instances.
3) Get SELECT privileges on GV$INSTANCE and GV$LISTENER_NETWORK, and make sure EZCONNECT is specified in the NAMES.DIRECTORY_PATH parameter of SQLNET.Ora file."
All the points in the above message have been addressed and still getting the same message when debugging.
