Running WebSphere Application Server on z/OS

Web-based workloads on z/OS

WebSphere® Application Server runs as a standard subsystem on z/OS®. Therefore, it inherits all the characteristics of mainframe qualities and functionality that accompany that platform, such as its unique capacity for running hundreds of heterogeneous workloads concurrently, and meeting service level objectives as defined by the user.

  • Consolidation of workloads
    A mainframe can be used to consolidate workloads from many individual servers. Therefore, if there is a large administration overhead or a physical capacity concern of many individual servers, the mainframe can take on the role of a single server environment managing those workloads. It can present a single view of administration, performance and recovery for applications that harness the mainframe's services during execution.
  • WebSphere for z/OS security
    The combination of zSeries® hardware- and software-based security, along with incorporated J2EE security, offers significant defense against possible intrusions. The product security is a layered architecture built on top of the operating system platform, the Java Virtual Machine (JVM), and Java2 security.
  • Continuous availability and WebSphere Application Server for z/OS
    WebSphere for z/OS uses the zSeries platform's internal error detection and correction internal capabilities. WebSphere for z/OS has recovery termination management that detects, isolates, corrects and recovers from software errors. WebSphere for z/OS can differentiate and prioritize work based on service level agreements. It offers clustering capability as well as the ability to make non-disruptive changes to software components, such as resource managers.
  • Performance and WebSphere Application Server for z/OS
    Performance is highly dependent on application design and coding, regardless of the power of the runtime platform–a defectively written application will perform just as poorly on z/OS as it would on another platform. That said, WebSphere Application Server for z/OS uses the mainframe qualities in hardware, and software characteristics incorporating Workload Management schemes, dynamic LPAR configuration, and Parallel Sysplex® functionality.
