drop table very slow in busy system EE 9.2.0.3

Hi,

we are running Oracle EE 9.2.0.3 on Linux 8.2 kernel 2.4.20-64GB-SMP Fujitsu-Siemens dual Xeon 2,8 GHz, 2 GB RAM, RAID 5. Shared pool standard 240 MB, Buffer cache 608 MB standard, no archivelog.

If the system is busy (huge import)
a drop table takes from 5 minutes to 20 minutes?

In Oracle 8.1.7 it was done in 1-20 seconds!

Anything wrong with undo time 10 hours?

How much do you enter here?

thanks in advance,

Toni
