Re: Help: oracle space problem. Error code:ORA-01652

Hi,

Just to add my two cents worth and perhaps clarify some points.

When you say the dba dropped and created a new segment do you mean tablespace ? Segments are physical storage assoc. with objects (e.g. tables, indexes) and reside within tablespaces. Temporary segments are built dynamicly and therefore can't be managed in the way you describe.

You can control how they are created by the tablespace's default storage (init/next extents and pct inc). I suspect the increasing size of the requested extension is a function of percent increase and how far your query has progressed and it's competition with other processes for temporary space.

Depending on the version you're on you might suggest the DBA look at making the tablespace a "temporary" tablespace. This is different than making it a user's temporary tablespace in that it modifies the way oracle manages physical space.
