The Topology Overview displays the association between one environment and one instance. An Environment Instance pair is created by either associating an Instance to an Environment on the Edit/Create Environment Wizard, or associating an Environment to an Instance on the Edit/Create Instance Wizard. Endpoints and properties values are mapped to those Environment Instance pairs.

Each Instance likely has a development environment, a production environment, and at least one testing environment. The association of Environments to Instances defines a matrix. Endpoint association and properties are defined at each intersection.

This table depicts four Environments identified as rows, and two Instances which are identified as columns. Each Environment Instance combination defines which Endpoint(s) host the Instance for that Environment, and the Environment-specific properties which are required to communicate to the underlying technology. Note that the SOA2 Instance in the DEV and SIT Environments do not have any Endpoints or configuration properties defined because SOA2 is not associated with those Environments.

The image below depicts the Environment Instance pairing for SOA2. In this case, the FlexDeploy SOA Plugin's soaDeploy operation was associated to the SOA2 instance. The soaDeploy operation defines several Environment-Instance-scoped properties that must be defined for the operation to succeed.


Instances are flexible enough to allow FlexDeploy to adapt to a variety of technologies and platforms. In Oracle Data Integrator, for example, an Instance is most likely one to one with a single installation, spanning all Environments (e.g. DEV, SIT, UAT, and PROD). In the case of Oracle WebLogic, a single installation is partitioned into one or more domains. So for WebLogic it makes more sense to map an Instance to each WebLogic domain, since each domain will require different property configuration to communicate with its servers.

Notice that in the table below the wls_customer and wls_order Instances (domains) share the same host/Endpoint in the DEV and SIT Environments, but only share some of the same hosts/Endpoint in the UAT and PROD Environments. Mapping the Instances to the WLS domains allows the flexibility to match the Endpoint and properties to your exact Topology.

Viewing Environment Instances

To view the Environment Instances that have been established select Topology from the menu, and choose the Topology Overview tab.

Every circle on the screen represents an Environment and Instance assocation. The configuration of these pairings can be viewed and edited by clicking the circle.


Updating Environment Instance Properties

Each Environment Instance pair has a Properties tab which summarizes the required properties that are associated to it. The circle on the Topology Overview will not become green if all of the required properties are not set (as well as an endpoint is assigned).


The properties are linked to the Environment Instance intersection because workflows or plugin operations associated to the Instance have Environment-Instance-scoped properties defined. These Environment-Instance-scoped properties must have values defined for every Environment to which that Instance is mapped. This provides, for example, the ability to define unique Weblogic Admin Server host and port for each Environment Instance.

See Properties chapter for more details.


Associating Endpoints to an Environment Instance Pair

The different colors of the circles indicates the level of completion of the configuration, see the table below for what each color indicates.

Description

All required properties are not set, and there is no endpoint associated to the Environment Instance pair.

Some required properties are set, but other required properties have been left empty. At least one endpoint is associated to the Environment Instance pair.

All required properties are set and there is at least one endpoint associated to the Environment Instance pair.


Each intersection has an Endpoints tab, which displays the different Endpoints that are associated to it. 


To associate an Endpoint to an Environment Instance association, click and drag one or more Endpoints from the right over to the main pane. The list of available Endpoints on the right can be filtered by entering all or part of the name or port into the Search field and the list will be automatically filtered. By default, only Endpoints which are active are available for association.

Once an Endpoint has been shuttled to Selected Endpoints optional Resource Types can be assigned. The Resource Types indicates what type of resources the Endpoint contains, which helps in determining which Endpoints should be selected to perform particular plugin executions. For example, the Weblogic plugin has Resource Types of WLS Admin Server, WLS Managed Server, and WLS Node Manager. Selecting the Resource Type(s) for each Endpoint tells FlexDeploy a little bit more about the Topology and enables it to direct work appropriately (e.g. to the Weblogic Admin Server vs. one of its Managed Servers).

To disassociate an Endpoint from the Environment Instance, click an Endpoint row and drag it back to the list on the right.

Click the Save button to save the changes and automatically return to the previous screen. Alternatively, click the Apply button to save any changes, but remain on the screen until the Back button is clicked.
