Hi all,

One of our solaris machines is running Oracle 8.0.3

A table reached the 2 Gb size and oracle failed due to the operating system file size limitation.

The information in the table is not relevant and can be deleted, but the table contains a lot of indexes.

I would like to know the best procedure to delete the information and reduce the size of the file.

Thanks for your help

Hi Michel, thanks for your answer.

I do not want the records in the table. Why is it necessary export/import?

By the way, when I execute the drop table command I get this error:

"unique/primary keys in table referenced by foreing keys"

Thanks for your help

So drop with the option "cascade constraints".
If you don't want the data you can truncate the table (after disabling the foreign keys).
Then you can try to resize the files but it may not be possible and so you have to export the objects in the tablespace and drop them before resizing the files and reimporting the objects.

Michel
