Default partition and prefix - 11-10-2005 , 02:59 PM






Hi

We use AS 2000 SP3. We pump data from a DB2 database and create MOLAP
cubes. When we create a partiton AS is creating an aggregation prefix
for it. The problem is when we process the cube it goes to the DB2
catalog to find the aggregation. Is the a way to tell AS not to go to
DB2 catalog for the aggregation ????


Thanks

What do you mean by this? What symptoms are you seeing?

Hi

When we process the cube AS is making a lot of reques to DB2. Here is
an exemple of one request.

SELECT TBCREATOR , TBNAME , NAME , COLTYPE , CASE COLTYPE WHEN 'BLOB'


THEN LENGTH2 WHEN 'CLOB' THEN LENGTH2 WHEN 'DBCLOB' THEN LENGTH2


WHEN 'ROWID' THEN LENGTH2 ELSE LENGTH END AS LENGTH , SCALE ,


NULLS , REMARKS , FOREIGNKEY , COLNO , DEFAULT , DEFAULTVALUE ,


TYPESCHEMA , TYPENAME


FROM "SYSIBM".SYSCOLUMNS


WHERE RTRIM ( TBCREATOR ) = 'DADD0' AND


TBNAME =


'Indemnisationbase_Indemnisationbase_1U'


ORDER BY TBCREATOR , TBNAME , COLNO


FOR FETCH ONLY

Indemnisationbase_Indemnisationbase_1U is the name you have in the
advanced panel of the partition wizard. I don't know why it goes to
DB2. And the RTRIM clause in the select causes a full table scan of the
system table.
