+GRP capability to allow you to undo the partition drop.
+
+If CREATE_GRP=Y, it will drop the partition, but the dedicated tablespace will be dropped only once the GRP has been removed.
+
+If using PDBs you’ve got this problem that you must allow drop tablespace with GRPs by setting a parameter:
+CDB$ROOT: alter system set "_allow_drop_ts_with_grp"=true;
+Setting that parameter will mean that a dropped tablespace will invalidate any GRPs and your ability to recover.
