Goal

How to identify the SEGMENT reported by a trace file generated by
dbms_space_admin.TABLESPACE_VERIFY or dbms_space_admin.ASSM_TABLESPACE_VERIFY

When these procedures report an inconsistency, they generate a trace file with information related to the affected segments. Trace file example for an inconsistency related to Overlapped Extents in tablespace USERS:

execute dbms_space_admin.TABLESPACE_VERIFY('USERS')

It generated a trace file with 2 affected segments:

Extent Map Entry Overlaps with Another Extent Map Entry
SegDBA: 0x0fc3e832 : ExtNo 3 UetDBA 0x2ec00091: ExtNbk: 32
SegDBA: 0x1000c8d0 : ExtNo 212 UetDBA 0x2ec00011: ExtNbk: 1280


The goal of this note is to identify the affected objects using the Relative Block Address (rdba) information.
