Abstract: You can determine the amount of CPU time used by your java programs in WebSphere Version 5 for z/OS with the obtainTotalCpuTimeUsed() method in the SMFJActivity class. This returns the total CPU time in microseconds accumulated for the enclave in which you are running.
Here is an example of code to return the total CPU time in microseconds accumulated for the transaction.
Also included is an application that uses these methods in an EJB, Servlet, and JSP. (Source is included.)
