got a 9.2.0.7 db with dictionary managed tablespaces. after execution of >exec dbms_space_admin.tablespace_migrate_to_local('EVIS'); extent management indeed becomes "local". with 40 tablespaces, i don't want to tackle the task of breaking it down to 4 or 5 differently sized tablespaces with uniform extents and figuring out which objects need to go to which tablespace. but my question is... is there a way to change allocation_type from user to system? i'm guessing this can only be done at creation time? here are the current values: TABLESPACE_NAME BLOCK_SIZE INITIAL_EXTENT NEXT_EXTENT MIN_EXTENTS ------------------------------ ---------- -------------- ----------- ----------- MAX_EXTENTS PCT_INCREASE MIN_EXTLEN STATUS CONTENTS LOGGING FOR EXTENT_MAN ----------- ------------ ---------- --------- --------- --------- --- ---------- ALLOCATIO PLU SEGMEN DEF_TAB_ --------- --- ------ -------- EVIS 2048 51200 51200 1 99 0 0 ONLINE PERMANENT LOGGING NO LOCAL USER NO MANUAL DISABLED OEM(version 9.2.0.1) shows that this tablespace is locally managed with automatic allocation and manual segment space management. not sure why it has "automatic allocation" since it just uses the storage values of the tablespace unless explicitly set during table creation. OEM(10g grid) shows allocation type = uniform. what??? thanks -doug- -- //www.freelists.org/webpage/oracle-l
