What happens if the defined default tablespace of a partitioned segment no longer exists?
If, during a reorganization, you delete a tablespace, for example, which is defined as DEF_TABLESPACE_NAME in DBA_PART_TABLES or DBA_PART_INDEXES, the tablespace name is replaced by a placeholder such as _$deleted$7$0. If you now perform an ADD PARTITION, it leads to the following errors: ORA-00959: tablespace ‘_$deleted$8$0’ does not exist You can correct this by adjusting the tablespace name using MODIFY DEFAULT ATTRIBUTES as described above. BRSPACE performs this adjustment automatically during the reorganization.
