Hi Dan, another consideration is to find out it there are any dependencies in their environment (Quest Shareplex, eg) to make you want to preserve object_id's across your re-org efforts.

Just out of curiosity, what's driving the reorg effort? Last time I looked under the covers at SAP, the SQL coming from the ABAP servers primarily did index-range scans from single tables. Then the servers would "join" data inside the buffers of the ABAP servers; to me the SAP on Oracle implementation looked as if they took their old MVS VSAM file structure and implemented each distinct file as a separate table in the new Oracle world.

Does your customer have quantifiable evidence to suggest that a table reorg effort will resolve any current performance issues?

Take care and regards,

Subject: SAP Reorgs

Hi,

I have a gig where they have a rather large SAP database...they want to reorg it...then
periodically reorg it. I'll find out this next week all the specifics.

I am wondering if anyone has any experience in doing reorgs on SAP databases. What I should
look for...what I should look out for...SAP specific things...which objects needs periodic
reorgs...which objects needs a better storage parameters... Any help/comments would be most
appreciated.

Thank you in advance.

Dan Hotka
