Comment No. 1 : now at that time i want to know how to delete data from undo tablespace without drop undo tablespace. Comment No. 2 : if i uncomment undo_management=AUTO parameter in init.ora file, the data for undo tablespace are not longer available through Flashback query ? overall i need some solution for old data (modified, deleted), which is not realated to our job, are unnecessary hold in data base space. so that the system will be runing smoothly.
