The answer is in the information you provided
ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified
CONNECT: sys/*****@PAYMOFDB
When Data Protector tries to connect to the Oracle database, it uses this method
connect user/password@SERVICE as sysdba
According to the error, this is not working. It may be caused by your user not having sufficient priveledges (sysdba) in Oracle; it maybe cause by an incorrect password; it may be caused stating the name fo the Service incorrectly
If you are pretty sure that you have the first two covered, check the file 'tnsnames.ora' on your Oracle server. The Service name is usualy the name of the instance, but does not have to be. The service name is case-sensitive
Nothing is going to work until this is run successfully
connect user/password@SERVICE as sysdba
