Hi, We are migrating the Single Instance Database into RAC ( 10g to 11g ). Hence as a requirement, our database converted all the tablespaces from dictionary managed to locally managed tablespaces uing the dbms_space_admin. However the tablespace segment space management are still in manual. Hence, we are getting alerts for inadequate chunk of free space which is required. Eventhougth when I extend the tablespace / adding the datafile, after some time, I am keep on getting inadequate chuck of freespace alerts. Some one give me idea for resolving such issues. Thanks in advance ! Regards, Raja -- //www.freelists.org/webpage/oracle-l
