pct increase

[AK]

Hi List , I have a table set with pctincrease 50. After growing many times now it is asking for 520M of disk space and I dont have that much space in dba_free_space . Now I want to change pctincrease to 0. So that it doesn't have spiraling requirement . But event after changing pctincrease to 0 this table is still coming in my list of monitored exntents which doesn't have room for next growth. Question is , when does oracle calcs next space requirement ? It looks like its precalculated .   -ak
