Modernize IT Infrastructure: Oracle Mainframe Rehosting Supporting Hybrid Environments For many large scale mainframe customers, the co-existence of rehosted and mainframe environments is a long term requirement. In some cases, they rehost an application at a time, or just some specific transactions and/or batch jobs that are responsible for peak MIPS consumption. By lowering the peak, the overall cost of the mainframe environment can be significantly reduced.

Oracle customers often run in such hybrid environments even before migration using a broad ramge of strong mainframe integration capabilities at an application and database level. In order to support such hybrid environments during multi-phase migration, or forever, customers can leverage:
