reorganization a datafile under EMC 12 c
Hello I'm using EMC 12c on linux x86_64 , I have a DB 11.2.03 linux x86_64 with a tablespace with allocated size 91 GB and allocated space used 3.3 GB.
When I try to reduce the File size from 91GB to 20 GB I get the error :
Failed to commit: ORA-03297: file contains used data beyond requested RESIZE value
Please : Is there a way with EMC 12c to reorganize automatically the size of this tablespace ? what you suggest in order to avoid the ORA-03297 ?
thanks for your help
