    - Customizing the http timeout on the Dynamic Workload Console
      You can increase the length of the HTTP connection timeout in the Dynamic Workload Console to allow more time for retrieving objects related to the z-centric environment.
    - Configuring the heartbeat checking interval for z-centric agents and dynamic domain managers
    - Configuring the connection between the z-centric agent and controller through a proxy
      You can configure that one or more z-centric agents connect with the controller through a proxy server, by defining the proxy properties in the ROUTOPTS statement and JobManager.ini file.
    - Starting and stopping HTTP subtasks
      An HTTP Server subtask and an HTTP Client subtask run the transmission of data between the scheduler and the IBM Z Workload Scheduler Agents on the distributed side. These subtasks automatically start at controller startup.
  - Defining user IDs and passwords with the USRREC statement
    Use the USRREC initialization statement to define the passwords for the users who need to schedule jobs to run on Windows™ workstations. You do not need to do this if you run native job types on non-Windows workstations.
  - Defining variables and passwords for local resolution
  - Defining and managing IBM Z Workload Scheduler Agent workstations in the database
    After defining the destinations of your IBM Z Workload Scheduler Agents, you need to define the IBM Z Workload Scheduler Agents as IBM Z Workload Scheduler computer automatic workstations.

Customizing the HTTP connection with the HTTPOPTS statement

HTTPOPTS statement to customize HTTP connection.

You can optionally use the HTTPOPTS initialization statement to define a number of parameters for IBM Z Workload Scheduler Agents and dynamic domain managers, for example:

Variable tables to be used when running job types with advanced options.
Job log retrieval parameters.

You do not have to define the TCPIPJOBNAME and the HOSTNAME parameters if you already have a TCPOPTS initialization statement that includes them. Define the job log retrieval parameters if you want to change the defaults.
