BUSINESS ARCHITECTURE IMPLEMENTATION WORK FRAME

Two development streams sharing a common metadata library to allow for the provision of Strategic goals based on market drivers and production volumes which are driven down to the Operational planning level to provide a roadmap by Brand/Channel/Pack for all markets.
 
 
MAIN OBJECTIVES/ BENEFITS

  • The number of database migrated to the new infrastructure was 4

  • The migration required upgrade from old and now unsupported 9i single node release running on SUNOS to the new 10g database version (10.2.0.3) running with RAC on Solaris 10.

  • Integration with the hardware load balancer (HLB) in a transparent way to the user.

  • Redundancy on both database and application nodes (including concurrent managers)

  • Minimum downtime required since all the companies that rely on these systems have 24/7 support/customer care.

  • Preservation of the internal custom procedures related to various tasks (for example automatic invoice faxing/emailing)

  • Configuration during the same limited timeframe of the staging environment that must be a perfectly identical copy of production.

SHORT DESCRIPTION OF PROJECT

The project started in December 2007 with the installation of the RAC and Oracle Homes. By January the 8-th 3 of the instances that made scope of the project were already ready for UAT. The testing took more than 1,5 months with more than 1500 users from each area involved in the process. The Vector team was assisting the customer onsite in case any issues occurred. Also, by 15th of February all testing was successfully finished. The cutover and the final migration to live was scheduled with a 16 hours downtime and another 8 hours testing from EMAAR's side.

The project finished in April after the last instance was migrated (each instance migration was scheduled according to managerial decision from each department).
