A Comprehensive Guide to IBM WebSphere Host Publisher Version 3.5

626 IBM WebSphere Host Publisher Version 3.5

19.7 Monitoring clone activity

The easiest way to monitor which clone is serving the request is by enabling the

display terminal trace option. By doing so, you will get a trace window in the Host

Publisher Server machine showing the port number used by the clone serving

the request. For information on how to set the display terminal option see 4.5.2,

“Traces” on page 93.

Once the display terminal trace option has been set, when you run an application

that uses a Host Integration Object, you will get a trace window showing all the

interactions between the Host Integration Object and the host application (for

example, CICS, IMS). The title bar of that window shows the port number of the

clone that is serving the request. These port numbers are allotted dynamically

when you create the clones. It will be different every time. In this scenario the

port number happened to be 8120 as shown in Figure 19-31.

Note: Running traces may create extra overhead and impact Host Publisher

throughput and performance.

19.8 Restrictions

Some restrictions applied when running Host Publisher in a cloned environment.

In this section we describe issues related to connection cleanup and using a user

list for user IDs and passwords.
