Oracle Solution for Error ora-31610

ORA-31610: cannot call this function from a non-master process

What triggered the Error:

Called a Data Pump process model function from a process which is not a master process.

What should we do to fix it:

Create a master process first. Then call the function from the master process. If this error occurs from a Data Pump client (e.g. expdp or impdp), try the operation again. If the error occurs again, contact Oracle Customer Support and report the error.
