Further action is optional. 3. rman_recovery_version NO Informational only. Further action is optional.The fixup scripts have been run and resolved what they can. However,there are still issues originally identified by the preupgrade thathave not been remedied and are still present in the database.Depending on the severity of the specific issue, and the nature ofthe issue itself, that could mean that your database is not readyfor upgrade. To resolve the outstanding issues, start by reviewingthe preupgrade_fixups.sql and searching it for the name ofthe failed CHECK NAME or Preupgrade Action Number listed above.There you will find the original corresponding diagnostic messagefrom the preupgrade which explains in more detail what still needsto be done.Perform Oracle 19c upgradeExecute DBUA (Database Upgrade Assistant)Monitor Upgrade Logs Post-Upgrade Check the current state of the Oracle Data Dictionaryspool regInvalid.txtcolumn comp_id format A15column comp_name format A30column version format A10set echo on-- query registryset lines 132 pages 100select substr(comp_id,1,15) comp_id, substr(comp_name,1,30) comp_name, substr(version,1,10) version, statusfrom dba_registryorder by modified/COMP_ID COMP_NAME VERSION STATUS--------------- ------------------------------ ---------- -----------RAC Oracle Real Application Cluste 19.0.0.0.0 OPTION OFFCATALOG Oracle Database Catalog Views 19.0.0.0.0 VALIDCATPROC Oracle Database Packages and T 19.0.0.0.0 VALIDXDB Oracle XML Database 19.0.0.0.0 VALIDOWM Oracle Workspace Manager 19.0.0.0.0 VALIDJAVAVM JServer JAVA Virtual Machine 19.0.0.0.0 VALIDXML Oracle XDK 19.0.0.0.0 VALIDCATJAVA Oracle Database Java Packages 19.0.0.0.0 VALIDCONTEXT Oracle Text 19.0.0.0.0 VALIDORDIM Oracle Multimedia 19.0.0.0.0 VALIDAPS OLAP Analytic Workspace 19.0.0.0.0 VALIDSDO Spatial 19.0.0.0.0 VALIDXOQ Oracle OLAP API 19.0.0.0.0 VALIDOLS Oracle Label Security 19.0.0.0.0 VALIDDV Oracle Database Vault 19.0.0.0.0 VALIDows selected.Application System TestingOnce the database has been upgraded to the satisfaction of the DBA, further testing by users and or developers is required.Check/Set Initialization parameter : COMPATIBLESet the COMPATIBLE initialization parameter to an appropriate value.
