Adding a Datastage Engine to an existing Infosphere Service
Posted: Wed Jun 11, 2014 10:21 am
Hi All,
Enterprise Edition - v8.7
We are hitting a performance bottleneck with multiple projects using the same ETL server for Data Integration requirement to load to both OLTP and DW databases.
Current topology is all 3 tiers on same Server!
Approach 1
(post job optimization and environment upgrades)
Move Engine Tier to separate server (or maybe have 2 Engines instead of 1)
Is this doable in an already existing environment or needs a full re-install?
Do we need to alter existing job designs in anyway?
(I believe recompilation may be required)
Any other considerations if we go this route
Approach 2
Separate the ETL servers itself, one catering to the OLTP cycle, which takes most of the time and resources currently, and the other to DW cycles
(Using this approach we could add more Datastage projects in the DW cycle in the future as needed)
Will this need purchasing a new Infopshere Information Server License?
Should migrating jobs to the new server cause a major challenge or should be more like an export/import/compile jobs (and test!)
Any other considerations if we go this route
Thanks,
VN
