Hello,



I am not a DBA, but frequently I have to install an Oracle database for development and test environments. 



So far I used the following approach to setup 19c from scratch:



    
  
  1.   runInstaller with "software only"
  
  2.   apply DB RU patch (e.g. 19.11)
  
  3.   apply the OJVM patch (e.g. 19.11)
  
  4.   run dbca to create the instance






I always thought (assumed) that if I apply the patches _before_ creating the database, running datapatch wouldn't be necessary (because the database was created with the patched software). 



But at least in one occasion, this approach resulted in a PDB that would only start up in "RESTRICTED" mode. 
Only after running "datapatch -verbose" this was fixed.



So my question is: is my assumption wrong, that I can skip the datapatch step if I install all patches prior to creating the database?



Do I need to run "datapatch -verbose" after applying the RU and then after applying the OJVM patch despite the fact that I don't have a database yet? 



Regards


Thomas
