2 undo tablespaces for Oracle rac 2 nodes pluggable database

in Database Administration (MOSC) 12 commentsAnswered ✓

I have oracle 19c rac on linux with 2 nodes and database 19c pluggable database;

ive noticed the belowl

some times when I issue show parameter undo i see that the default undo tablespace is UNDOTBS1 and sometime i get UNDO_2

does this means i have 2 undo tablespace for the PDBs

knowing that at the cdb level its clear that each instance will have its own undo tablespace


node1: UNDOTBS1

node2: UNDOTBS2


what is confusing is that why logging to PDB level shows different UNDO tablespace at each time
