Answer 1

It looks like your Oracle instance is failing you. But let's roll it up from the beginning.

IMPDP in Parallel

To execute the IMPDP command with the PARALLEL parameter you have to meet the following requirements:

• This parameter is valid only in the Enterprise Edition ^(check) of Oracle Database 11g or later.

• To import a table or table partition in parallel (using PQ slaves), you must have the DATAPUMP_IMP_FULL_DATABASE ^(check) role.

• Transportable tablespace metadata cannot be imported in parallel.

• Metadata cannot be imported in parallel when the NETWORK_LINK parameter is also used

• The following ojbects cannot be imported in parallel:

  • TRIGGER
  • VIEW
  • OBJECT_GRANT
  • SEQUENCE
  • CONSTRAINT
  • REF_CONSTRAINT.

ORA-00800 Errors

• ORA-00800: soft external error, arguments: [Set Priority Failed], [VKTM], for Oracle Linux (Doc ID 2718971.1) (Oracle on *nix systems)
• ORA-00800: Soft External Error, Arguments: [Set Priority Failed], [VKTM] [Check traces and OS configuration] (Doc ID 2551359.1) (Oracle on IBM AIX systems)

ORA-00313 Errors

• ORA-00313 at Startup After a New Redo Log Member is Added (Doc ID 1005110.6)

ORA-07445

• ORA-7445 Troubleshooting Tool (Oracle Online Troubleshooting Tool)

This option requires you to upload an IPS package to Oracle in order for them to analyse the data. If you create an SR with Oracle and supply the error message ORA-7445 in the case, then you will be automatically redirected to this tool. There is however a downloadable version under that link.

If All Else Fails

There do seem to be issues when trying to import 12c objects into 19c so you might want to contact a certified Oracle consultant or if you have a Support Identifier with Oracle open up a new Service Request.
