Instances of Tivoli Workload Automation

|During the installation of Tivoli Workload Scheduler for z/OS, decide if you want |to install into an existing instance of Tivoli Workload Automation or to create a new instance.

Each instance of Tivoli Workload Automation can contain the following:

One instance of the embedded IBM® WebSphere Application Server on |which can run: |
- One instance of a master domain manager, backup master domain manager, dynamic domain manager, backup dynamic domain manager, domain |manager with distributed connector, or fault-tolerant agent with distributed |connector
- One instance of the Dynamic Workload Console
- One instance of the Tivoli Workload Scheduler for z/OS® Connector

If no other Tivoli Workload Scheduler component (master domain manager, backup master domain manager, dynamic domain manager, |backup dynamic domain manager, domain manager with distributed connector, or fault-tolerant |agent with distributed connector) is installed, one instance of a |domain manager or fault-tolerant agent without a distributed connector.

Only one Dynamic Workload Console can be installed on a workstation and can be installed as follows:

In an existing Tivoli Workload Automation instance
In a new Tivoli Workload Automation instance
|Outside any Tivoli Workload Automation instance, using an existing external |instance of Tivoli Integrated Portal.

Thus, if you are installing into an existing instance of Tivoli Workload Automation, you can install certain products or components, depending on the products or components that currently exist in that instance. Table 35 describes the actions that you can perform in each different scenario.

|Table 35. Installing into an existing instance of Tivoli Workload Automation
\|If the existing Tivoli Workload Automation instance contains:	\|You can perform the following:
\|A Tivoli Workload Scheduler version 8.6 master domain \|manager, domain manager, or backup master or Dynamic Workload Console version 8.6	\|Install a Tivoli Workload Scheduler for z/OS version 8.6 connector on a common embedded WebSphere Application Server.
\|A Tivoli Workload Scheduler version 8.5 or 8.5.1 master domain manager, \|domain manager, or backup master or Dynamic Workload Console version 8.5 or 8.5.1	\|Take no action.
\|A Tivoli Workload Scheduler for z/OS version \|8.3, 8.5, or 8.5.1 stand-alone connector	\|Upgrade that component.
\|A Tivoli Workload Scheduler for z/OS version 8.6 connector	\|Take no action.
\|A Tivoli Workload Scheduler for z/OS version \|8.5 or 8.5.1 shared connector on a common embedded WebSphere Application Server	\|Upgrade the connector if the Tivoli Workload Scheduler component \|is V8.6.

Note:

The advantage of installing a product or component into an existing instance of Tivoli Workload Automation is that all of the data that is required to configure the component is already present and displayed in the wizard. In some cases, data from the existing instance is reused automatically. In other cases, data is retrieved as default values that you can choose to use or edit.
