DBA_SEGMENTS

hi all,

I'm seeing a rather unusual output from dba_segments. I've just migrated from Oracle7.3 to Oracle8.0.6. I got an error while running cat8000.sql that the table SYS.SOURCE$ has reached its max extents.
So I run this query to make sure I'vent reached my max_extents and I get 2 rows. could anyone tell me why i've two entries for the same table in dba_segments view????

SVRMGR> select initial_extent, next_extent, max_extents, extents
2> from dba_segments where segment_name = 'SOURCE$';
INITIAL_EX NEXT_EXTEN MAX_EXTENT EXTENTS
---------- ---------- ---------- ----------
12288 1290240 249 12
12288 12288 249 249
2 rows selected.

Thanks so much,

select the owner too, in my database there is only one (sys), but perhaps system owns an object of the same name.

Duh! i didnt of think of that........thanks so much. Actually owner "Migrate" owns the other object.

Thanks again,

Your DB looks like having something corrupted.
Try to execute this query and be sure to have only a record in your output (It should be sys).

select owner from all_objects where object_name='SOURCE$';

You have reached maxextents for one of your system objects. While not the greatest thing to happen, it's not that big of a deal either. Just alter the object in question and set it's maxextents to unlimited. For example:
alter table sys.source$ storage (maxextents unlimited).

Hi,
I get two entries for the same object in the all_objects view. One is owned by "migrate" and other one bu "sys". A question, since i've completed my migration is it appropriate to delete the user "migrate" and delete all the objects owned by this user???

SVRMGR> select owner from all_objects where object_name='SOURCE$';
OWNER
------------------------------
SYS
MIGRATE
2 rows selected.

Or is there a serious problem that "migrate" user owning objects that should be owned only by sys?

when I count the number of objects owned by "migrate" result is 136

SVRMGR> select count(*) from all_objects where owner = 'MIGRATE';
COUNT(*)
----------
136
1 row selected.

Thanks for all your help.

Of course nobody else should be the owner of sys's objects.
It'd be curious to know how you have an user with the same objects as sys user has.
Howevere if your sys user work properly you can try to delete your user MIGRATE payinh attention if the DB work correctly.
But it's not a nice situation.
Good luck.
