Preparing to use Multi-site Workload Lifeline

You need to evaluate TCP/IP workloads and grant users authority before you can configure Multi-site Workload Lifeline to balance workloads between the two z/OS® sites.

You must meet the following requirements:

  • All z/OS systems should be at the V2R4 or higher levels.
  • All Linux® on z Systems® guest systems must be at the SUSE Linux Enterprise Server (SLES) 10 SP4 or Red Hat® Enterprise Linux (RHEL) 5 version 5.8 level or higher levels.
  • For workloads consisting of server applications, ensure the following statements are true:
    • You must have at least one first-tier external load balancer that supports the Server/Application State Protocol (SASP). The load balancer must have IP connectivity to each second-tier load balancer. The second-tier load balancer is another external load balancer that supports SASP, an intermediary node, and/or a z/OS sysplex distributor that runs on a target system in the site.
    • The applications that are identified to be load balanced must be able to run on target systems that are in different sites, and must be able to access data sources that are synchronized across the sites.
  • For workloads utilizing IBM® MQ clusters, ensure the following statements are true:
    • All MQ queue managers must be at IBM MQ 9.0.0 or higher levels.
    • The MQ queue managers that host the MQ cluster queues for the workload must be a member of an IBM MQ cluster in a supported configuration. See MQ cluster workload configurations for information on supported configurations.
    • MQ queue managers that host the MQ cluster queues for the workload must have access to data sources that are synchronized across the sites.
