corrupted oraclespatial/arcsde layer

mollythompson — Sun, 06 Jun 2010 02:16:53 GMT

I have oracle spatial table myschema.mytable1 on oracle instance - instance1
I have other attribute table mytable2 on oracle instance - instance2.
There is NO link between these two tables...

i have registered mytable1 as sdelyaer so that i can see it in arcgis.

I have a small tool i developed using VB.net and in that tool, i am have some code like this -
        Dim iselset As ISelectionSet
        Dim myfeatcur As IFeatureCursor
        Dim iqryfil As IQueryFilter
        iqryfil = New QueryFilter()
        iqryfil.WhereClause = " objectid >0 "

        myfeatcur = fetlayer.Search(iqryfil, False)
        'fetlayer is the sde-layer i created using sdelayer command of mytable1

Now when i loop through that myfeatcur, for some features, I get wiered error message - saying that mytable2 does not have OID field!!!! When there is no link between mytable1 and mytable2.

Everthing was working fine before.. Since last few days i am getting this error.. Does it mean my data in that layer is corrupted? I can still easily see that layer in arcmap and arccatalog.
Is there any way to check this layer's data?

Thanks a lot...

What version of Oracle are you using (A.B.C.D notation)?

What version of ArcSDE are you using (including service pack)? What version of
ArcGIS are you using (w/ SP)?

Please provide the 'sdetable -o describe', 'sdetable -o describe_reg', and 'sdelayer -o
describe_long' output for table1, plus the USER_SDO_GEOM_METADATA content
for that table.

Objectids should always be positive non-zero values, so your where clause shouldn't do
anything. What does "SELECT COUNT(*) FROM table1 WHERE objectid <= 0" return?
How about "SELECT COUNT(*) FROM table1" and "SELECT COUNT(DISTINCT objectid)
FROM table1"?

If anything, it's not the layer which has been corrupted, but the instance. Have you
used DROP TABLE on any table registered with ArcSDE, or any layer registered with
the geodatabase? Has the 'table2' table ever existed in instance1?

If you use SQL to DROP registered tables, your geodatabase registry could be corrupted,
which can produce cross-association when new layers are registered. At this point, you
really ought to contact Tech Support, since they have the tools to diagnose and fix registry
issues.
