Hi,
I am getting the following error in UNDO TABLESPACE
while running our scenario is there any way resolve it

 ORA-30036: unable to extend segment by 1024 in undo tablespace 'UNDOTBS1'
ORA-27059: skgfrsz: could not reduce file size
OSD-04005: SetFilePointer() failure, unable to read from file
O/S-Error: (OS 112) There is not enough space on the disk.
ORA-27059: skgfrsz: could not reduce file size
OSD-04005: SetFilePointer() failure, unable to read from file
O/S-Error: (OS 112) There is not enough space on the disk.

Can its possible to shirnk the objects found in the tablespace but its segment type is different or we need to increase our rollback segment parameter high for your information our rollback segment parameter value is shown below

SQL> show parameter rollback_segment

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
max_rollback_segments                integer     73
rollback_segments                    string
transactions_per_rollback_segment    integer     5

thanks,

Not in UNDO tablespace

Irrelevant with undo tablespace.

- Find if there is no session that has been left without committing (TOAD for instance)
- Enlarge your undo tabespace
- Decrease your undo_retention parameter

Also some 9i versions have a bug that precludes Oracle from releasing free space. Have a look at Metalink if your are impacted by this.

Regards
Michel
