This affects any address spaces that execute PGM=KLV, namely: z/OS ITM TEMS, z/OS OMEGAMON TEMAs, and z/OS OMEGAMON CUAs Previously a TIME RESET command would need to be issued to each address space after the z/OS system local clock was changed. With APAR OA46343, the code will check every quarter of an hour for a change of more than two minutes, forward or backward, in the z/OS system local clock; if a change is detected, the ITM Engine clock is resynchronised with the z/OS system local time. Using... [More]

Recently the OMEGAMON XE for CICS agent code for v4.2.0 was updated to fully implement the Change in value function for CICS attributes in situations.
As we all know, situations can have conditions such as TRAN=CEMT or COUNT>10; similarly there is a "delta" condition actually called "Change in value" so the condition would be Change-in-value for COUNT>2. So, if the COUNT changes by more than 2 during the situation sampling interval then the situation fires. By applying the correct PTF (UA63181) for APAR... [More]
On z/OS data collected during the OMEGAMON history collection process is stored in the Persistent Data Store (PDS). In this blog entry we will provide some insight into how to effectively monitor the PDS maintenance process. The PDS is a set of pre-allocated flat files that are continually reinitialized and reused. T he PDS maintenance process is an automated process which should not require intervention by the system administrator. However, an understanding of the PDS maintenance process will be helpful to system administrators who want to... [More]

I recently spoke with a support representative for OMEGAMON XE for CICS TG on z/OS, v4.2.0 and discussed customer inquiries on any performance issues that were made over the last quarter. He informed me that APAR OA34597 and OA31693 were authored to address and improve some key aspects of performance in the product's last release. One customer reported a performance degradation problem in the agent address space and inquired whether the development team could reduce the amount of CPU usage when monitoring multiple CICS Transaction Gateway...

Recently, I worked with an airline company to identify why a few transactions out of hundreds per second were failing. Many z/OS applications act as a TCP/IP server and accept connections from users or applications on other hosts and mobile devices. The application at this customer that is experiencing problems does accept connections from end users, but it also acts as a TCP/IP client to retrieve information from servers running on Linux. Some of the transactions between the z/OS application and Linux servers were failing. Here's a brief... [More]
Do you ever wonder who is using the most resources in your SYSPLEX right now? Now with OMEGAMON XE for zOS 5.1.0 in the Enhanced 3270 there is workspace that shows the top 10 consumers in your SYSPLEX.
