Hello I have a database with some strange temporary segments under SYS schema seen from dba_segments as follows: OWNER SEGMENT_TYPE SEGMENT_NAME TABLESPACE_NAME ------------------------------ ------------------ ------------------------------ ------------------------------ SYS TEMPORARY 84.41971 TBS_DON_DATA SYS TEMPORARY 84.13427 TBS_DON_DATA SYS TEMPORARY 84.12659 TBS_DON_DATA I remember see these sort of names when a index is being rebuilt but this is not the case. They are constantly there. This happened after transporting 3TB Tablespaces from a 10g database running on Solaris to a 2 Nodes Linux x86-64 RAC running in 11g. any clues? Thanks -- LSC
