end-of-file on communication channel ERROR ! --Please Help

Hi All.
I'm running Oracle DB ver 8.1.5 on sun solaris 2.6 for about a month, Yesterday I tried to run an SQL query to delete some records (about 10,000).
The query took a long time (although it was a simple one) , and after a few minutes it reported :
SQL> @del1.sql
delete from BASIC1 where opname like 'DISC' *
ERROR at line 1:
ORA-03113: end-of-file on communication channel

Later on I tried to run another deleting query which is almost as the first one
and got the following error:

ORA-01562: failed to extend rollback segment number 1 ORA-01628: max # extents (121) reached for rollback segment RBS1PRO

How can I solve this problem ?
Is it the same problem in both cases ?

Thanks a lot .
