Shrink operations can be performed only on segments in locally managed tablespaces with automatic segment space management (ASSM). Within an ASSM tablespace, all segment types are eligible for online segment shrink except these:
IOT mapping tables
Tables with rowid based materialized views
Tables with function-based indexesSince this is an IOT, any chance there is an IOT mapping table?
Since this appears to be a data warehouse, any chance there are ROWID based materialized views or function-based indexes?
