For security requirements for the Xmanager and Xnet started tasks, see Started Task Security Requirements.
  • Xmanager (PTXMAN)
    The PTXMAN started task for the Xmanager (Execution Manager) must be started and active for all
    that run under the PTLDRIVM driver. This processing includes the TSO/ISPF online environment, batch jobs, and other jobs that are necessary to complete the installation and customization process.
    Xmanager instances are known by a four-digit ID (XMANID). This ID is specified when completing the SETUPxx global parmlib member during the post-installation configuration.
    The PTXMAN started task must be running at the same release or maintenance level as the release or maintenance level being installed. To complete the post-installation configuration process when a previous release or maintenance level of the same major release of the products is installed and running, start an alternate PTXMAN or recycle the current PTXMAN.
  • Xnet (PXNPROC and PXNPROCE)
    The Xnet (Execution Manager Networking) started tasks (PXNPROC and PXNPROCE) require the following software:
    • IBM z/OS with TCP/IP communications (any supported release as documented in the z/OS Compatibility Matrix)
    • One
      of the following external security manager products with the System Authorization Facility (SAF) interface enabled:
      • ACF2
      • Top Secret
      • IBM RACF
    PXNPROC and PXNPROCE also require that the Xmanager started task is up and running always. Detailed information about customizing Xnet before use is provided in the post-installation configuration tasks.
  • Mainframe Team Center - Database Management for Db2 for z/OS user interface started tasks
    The primary Mainframe Team Center - Database Management for Db2 for z/OS components include:
    • ESMPROC
      (in
      ccs_hlq.
      CAW0PROC)
      CCS ESM Microservice (external security manager microservice, an ESM security services server with an embedded Tomcat)
    • PXMDS
      (in
      dbm_hlq.
      CDBAJCL)
      Database Management Data Service (data request REST API and router for the
      with embedded Tomcat)
    • MTCDBM
      (in
      dbm_hlq.
      CDBAJCL)
      Mainframe Team Center user interface server with embedded Tomcat
    • PXNPROC
      and PXNPROCE (in
      dbm_hlq.
      CDBAJCL)
      Xnet (communication portal to the
      product sets, which are coupled to the Xmanager)
    • PTXMAN (in
      dbm_hlq
      .CDBAJCL)
      Xmanager (Execution Manager) started task.
    • OFAPROC (in
      dbm_hlq
      .CDBAJCL)
      Object Framework Services Agent (OFA) started task.
    On z/OS, each of these components appears as a started task (STC).
  • SYSVIEW for Db2
    requires two started tasks to be active:
    • (Optional) The PC task (one per partition)
    • The data collector (one per monitored
      Db2
      subsystem)
