I want to reorganize the SYS objects in my database so as not to use so many extents.

Specifically, I have:

TableName Extents Size

IDL_UB1$ 663 86 MB
SOURCE$ 209 54 MB
IDL_UB2$ 53 6 MB
DEPENDENCY$ 35 4 MB
IDL_SB4$ 24 3 MB
IDL_CHAR$ 18 2 MB

I have read on this forum that SYS objects are not included in an Export/Import.

I would like to find a way to minimize the extents in some of these objects.

Any ideas?

Thanks
