Total number of data files in CDB / PDB database

in Database Administration (MOSC) 5 commentsAnswered ✓

Oracle 19.20 - 4 node RAC enterprise Oracle database

OS: Oracle Linux 7

What is the best query to figure out how many db file do i have in my database? I don't want to exceed the parameter db_files = 400.

Is it DBA_DATA_FILES + DBA_TEMP_FILES?

  1. we have 3 CDBs and each have two PDBs.
  2. When I query the the PDB, it shows the db_files value = 400 (select * from v$parameter where name like '%db_files%' select * from v$parameter)
  3. when I count DBA_DATA_FILES + DBA_TEMP_FILES, they are 239
