Knowledge Management

Question:
Hi
Im at a client who are implementing both ERP and ISU. Both these will be installed on the same box.
Are there any risk involved in this type of landscape ie. data corruption etc.
Answer:
Nope, we have both.
IS/U uses an independent set of tables. Be extremely careful with the sizing, if you are involved in this, 'cause we currently have a 25GB monthly growth factor.
Answer:
For performance and maintenance reasons, I would highly suggest putting at least the Production boxes on seperate servers. Data corruption shouldn't be a problem, but while these are both OLTP systems, it will be difficult to pinpoint bottlenecks and slow performance on one system risks dragging down the other. Also, any downtime on the server will affect your complete productive environment.

Hardware for ISU is expensive; U need a robust server with lots of RAM to accomodate a large SGA for Oracle + 100 - 500GB~ of disk space so you might as well include the ERP along, which consumes less resources. (our sum for initial_extents in Oracle is 137GB, your starting figure) Having 2 boxes for production means also 2 boxes for DEV and 2 for QAS if they want the latter separate from development. Instead the 2nd server could be used for high-availability configurations, i.e. standby or RAC. I would suggest 1 box for DEV+QAS and 1 for production initially, which could be expanded to 1 for DEV, 1 for QAS and 1 for PRD, maybe a small one for IDES.
