RE: System tablespace corrupted

Waleed, Michael,


Thanks for both of you for your suggestion. I did dropped(tuncate did not 
work) the corrupted  table, recreated usinf import from other database and 
compiled invalids. Full export error gone now.
Thanks again for experimenting this issue.

But dbv still gives the error pointing to one block as corrupt page 223 is 
influx most likely Media corrupt and page 224 is marked corrupt.

Should I restore it from cold backup to get rid off this error?

Regards
Rafiq

It's not a critical table, and if you are not using consumers group it
should have only (four rows):

OBJ#    NAME    MANDATORY               CPU_METHOD      DESCRIPTION
STATUS
2534    OTHER_GROUPS            1               ROUND-ROBIN     consumer
group for users not included in any group in the active top-plan
ACTIVE
2535    DEFAULT_CONSUMER_GROUP  1               ROUND-ROBIN     consumer
group for users not assigned to any group
ACTIVE
2536    SYS_GROUP                       1               ROUND-ROBIN
Group of system sessions
ACTIVE
2537    LOW_GROUP                       0               ROUND-ROBIN
Group of low priority sessions
ACTIVE

Rebuild the table and reload from another database.
Check there is no triggers on the table, also check other object
dependencies on this table.

Truncating the table and reloading it may work since it will not try to
read the blocks.

Thanks. Table name is

SQL> select count(*) from sys.RESOURCE_CONSUMER_GROUP$;
select count(*) from sys.RESOURCE_CONSUMER_GROUP$
                          *
ERROR at line 1:
ORA-01578: ORACLE data block corrupted (file # 1, block # 223)

Subject: System tablespace corrupted


Env: Windows 2000 SP 4 Oracle 9.2.0.5

While exporting full database, it was observed that there is 1 block
is=3D20
corrupted and other is fractured as per dbv. After checking it was
tracked=3D20
as a sys.table. dbinv alos points that corrupt block due media failure.
SA=3D20
ran Compaq provided utility which says no corruption of media.

Database is a development instance and no archive on. Simple way to
restore=3D20
complete database from cold backup of previous week.

Is there any other way to recover the table completely. DBMS_REPAIR
package=3D20
does not look to work for complete recovery. Full export hanging
after=3D20
generating errors for that block.

Regards
Rafiq
