An energy provider needed to use its Plant Information Management System (PIMS) to manage the work and materials flow for its nuclear power plants.
Shadowbase Solution: Asymmetric Capacity Expansions
- The provider uses heterogeneous replication to replicate data stored in IMS files from IBM zSeries servers to an operational data store (ODS), residing on a Solaris Server, where the data is used to support reporting requirements.
- Once on the ODS, the data is then further replicated to other SUN Solaris Servers using an Oracle database for an imaging application.
- By offloading the reporting from the IBM mainframe, savings of over $1 million USD annually for disk (DASD) costs and CPU charges are attained.
- Additionally, near-real-time replication gives the users immediate access to current data, rather than day-old data provided by the prior implementation’s batch processing cycle.
