I'm experiencing an odd issue and can't seem to wrap my head around this particular limitation.

I have a single CDB hosted on DB System instance with enabled Data Guard on it. Now I can't create more than one Pluggable Database at a time neither using OCI UI, API calls or Terraform - I get an error indicating that creation of PDB is not possible when another PDB is in a Provisioning state on a Data Guard protected CDB.

Am I missing something here? How do people deploy multiple PDBs in such CDBs then? If you want to create, say, 30 new PDBs - each one taking around 10-15 minutes to create, then that would take around 8 hours to finish. Is that a normal business scenario when using Oracle services or am I doing something wrong here?
