Example of an Application Making a Request

This section provides an example of how an application that puts a request to TWS Automation is defined in TWS.

The application name is MAINT. This application consists of three operations:

Stop RMF on the target system
Schedule a batch job
Restart RMF on successful completion of the batch job

Figure 1 shows the initial panel in the application creation process.

GROUP DEFINITION   ===> ________________  Group definition id                  
SMOOTHING FACTOR   ===> ___   LIMIT  ===> ___  Deadline Feedback options

In Figure 1, certain fields, such as calendar ID, are not used. However, TWS Automation does not preclude the use of normal application and operation functions.

Selecting OPER as a primary command allows the entry of individual operations for this application.

In Figure 2, three operations are defined. The first and third send requests to TWS Automation in the NetView domain that is associated with the NV00 workstation. The second is a batch job named RMFMAINT that performs the batch maintenance tasks.

Selecting TEXT as a primary command allows entry of the operation text. TWS Automation uses the Operation text field to contain the request and up to two optional parameters for operations with the workstation defined for TWS Automation. Figure 3 shows the resulting operations text detail panel.

In the applications, TWS Automation defines TWS requests in a generic manner. Figure 3 shows the MAINT application with the first and last operations defined for the NetView workstation NV00. The requests that are forwarded to the NetView workstation NV00 are STOP and START. These requests are expanded by definitions in the policy database into commands; see Executing TWS Requests with TWS Automation.
