Not much found on this. From the Oracle/SAP integration Guide
Oracle operating system that is added to the following user groups:
- Operating system user account Oracle operating system that is added to the following user groups:
ORA_DBA and ORA_SID_DBA local groups
-Oracle database user Database user account granted at least the following Oracle roles:
sysdba
sysoper
See if you can connect to the Oracle SID using 'sqlplus' the same way Data Protector would
sqlplus nolog
connect username/password@SERVICE as sysdba
connect username/password@SERVICE as sysoper
If you are unable to connect, this is not a Data Protector issue, and you need to have a discussion with your DBA
