Situation @Shell DownstreamBW on HANA Migration & BW Solution Roll Out

  • Planned BW Roll Out for a large Business Unit (US Fuels) in 7/ 2014

  • HANA Migration before this point in time (10/ 2013 or 2/2014) means that BW development for US Fuels will run in parallel with HANA Migration activities and dual productive BWs (BW on HANA and BW on Oracle)

  • How to eliminate risks for US Fuels roll out?

Y weeks HANA/ Oracle in parallel

X weeks prepare HANA migration

US Fuels BW Development

Situation @Shell DownstreamBW on HANA Migration & BW Solution Roll Out

How to eliminate risks for US Fuels roll out?

US Fuels development is fully done on BW Oracle Dev-system until HANA migration is successfully completed (end of parallel run of BW Oracle Prod and BW HANA Prod)

Handover of US Fuels development to BW HANA Dev-system before Prod migration will take place – BW Oracle Dev-system as backup

  • General remarks:

  • First of all there are no adoptions to BW solutions (BWSP) on Oracle needed before a migration to BW HANA to run smoothly on BW on HANA!

  • BW on Oracle and BW on HANA is the same BW, the same code ! BW notices in which environment it is running.

  • There might be some adoption in Transformation rules (coding of routines) necessary after migration to HANA – I gave you the two –pager

  • One measurement is providing hints to the HANA DBSL and HANA itself – so this would not affect negatively affect a BW on ORACLE running in parallel with BW on HANA for a certain time

  • The other adoption is with select singles & working with internal tables – I cannot see a negative impact for BW on Oracle

  • Housekeeping on BW Oracle is recommended before migration (s. other worklist items) – but I am confident that your BW is in a good state -> these topics should be discussed in a future BW HANA migration assessment

  • No changes in BW on HANA possible as all changes in BW HANA Devwill be wiped out if the Objects are transported again from BW Oracle Dev

  • As no development in BW on HANA dev meaningful – no BW on HANA feature usage until handover

  • BW solutions on BW HANA prod will remain Oracle-like until handover of BW dev to BW HANA dev-system

US Fuels Dev

  • All Fuel dev done on BW on HANA dev

  • Limited (to be defined) usage of BW HANA features and no new LSA++ design (must be controlled)

    • Allows e.g. usage of HANA-Optimized DSOs as they are in a transport to BW ORA converted to STD DSO

  • No changes in BW OraDev except (will not be overwritten by transports from BW HANA dev – to be verified!)

    • Oracle specific changes like data class (tablespace) assignments

    • Aggregates creation

  • Oracle track remains fully functional until retirement – makes overall risk acceptable
