Thanks a lot for ur help, Rafiq. I have acted as per ur recommendation
and asked the customer to try the delete job again.....have not received
a feedback from them yet but sometimes they only revert back to me if they
have faced a problem again.....if I do not hear anything by this evening,
I will assume that it has worked.
Regards,
Samir

Is your tablespace fragmented as it is not finding contingous extent ..
TRy to coalesce your subject tablespace and try...
you can use following script to check whether coalesing is required or not..
If percent is < 100 then coalesce it..
select substr(tablespace_name,1,10)TS_NAME,total_extents
"Total_Extnts",extents_coalesced,round(percent_extents_coalesced,0)
from dba_free_space_coalesced
order by tablespace_name

All,
The following is the pitiable scenario I am in and would really appreciate a
bit of help :
We were running a long running delete job which gave the following error :
Oracle8 Enterprise Edition Release
8.0.5.2.1 - Production
PL/SQL Release 8.0.5.2.0 - Production
SQLWKS> EXECUTE
PKG_PAS_AnnualDataMaintenance.Delete_OldData (2000,
'/home/sqribe/work/live', '2000AnnualDataDelete.log');
ORA-01562: failed to extend rollback segment
number 8
ORA-01650: unable to extend rollback segment
RSUNDB08 by 50 in tablespace RSUN425
ORA-06512: at
"PAS.PKG_PAS_ANNUALDATAMAINTENANCE", line 66
ORA-06512: at line 2
I don't understand why it ran out of rollback space. The rollback segment
has a virtually unlimited number of extents, so the only explanation I can
see is that this particular rollback segment expanded until it exceeded the
space allocation for the whole tablespace RSUN425, which is 3,000M. However,
Oracle Storage Manager shows only 200M of the tablespace used, and it also
shows high water marks against each rollback segment, none of which exceeds
400M. This would suggest to me that none of the previous month's deletions
exceeded 400M per month, so why should it fail on this particular one when
it had nearly 3,000M available?
Is there something I am not understanding about rollback segments ??
Thanks and Regards,
Samir
