174 WebSphere Portal on z/OS
5.3.4 The test cases
The main intention for the test is to verify that WebSphere Portal on z/OS in a
sysplex behaves like WebSphere Portal for Multiplatforms when the latter uses
horizontal or vertical scaling. The intent was not to exploit all possible scenarios
within the sysplex on z/OS, for example, session persistence and failover
scenarios were not tested.
One problem during these tests was to show in which server instance of the
portal a special scenario was executed. Two tools were used to solve this
problem: the Vertical Cloning Test Portlet and a modified Login class that writes
The Vertical Cloning Test Portlet that is used in the class IBM WebSphere Portal
Version 4 Administration (WebSphere Portal for Multiplatforms) was installed.
This portlet was deployed without change on the z/OS portal and displayed the
Clone identification, as shown in Figure 5-11 on page 175.
