NetView for z/OS REXX samples are available for integrating NetView with the zAware Server. These samples help identify when system anomalies are found by zAware and allow further automation and problem diagnosis using NetView functions. Further information about this integration, the samples for downloading and information about zAware itself can be found by clicking here for the NetView for z/OS Wiki Integration Scenarios page.
Just a reminder that OMEGAMON XE for zOS (4.2.0 and 5.1.0) will use RMF to collect metrics like Coupling Facility, XCF and Locking. This is a way to lower the OMEGAMON collection cpu used for customers already collecting this information with RMF. We plan to continue to use RMF more over time for OMEGAMON collection.
Here is an issue I ran into today. Lets look at the pdf file attached: Process Gone WIld PDF On Page 2 - I saw two alerts this AM - One for a possible CPU Looping address space on LPAR SYS and a second one for a USS Process using a large amount of CPU time. Lets look at these issues on LPAR SYS. On Page 3 - We go to OMEGAMON XE for zOS and look at LPAR SYS and ask which Address Space maybe Looping? It is CTG90GP. Now I can cancel this right here but I really want to understand it better... [More]

When you are making global entry changes (KC2GLBxx) and you want these changes to be picked up, a simple OMEG RECYCLE will suffice. You do not have to recycle your CICS region or recyle the classic started task or even perform a OMEG SHUT, OMEG REMOVE or OMEG INIT for that matter. The only time you need to do anything other than a OMEG RECYCLE is if the name of your GLOBAL (KC2GLBxx) has changed. Then you need to update the DD card in the CICS region. In this case, however, you do need to recycle the CICS region. Note: It is very important... [More]

Imagine for now that there is a z/OS operation... [More]
