Welcome to the System z Management Blog, where you can read the perspectives from System z experts. This Blog provides insights into the System z solution, as well as technical details about specific IBM products.
In September 2014, we released Version 1.2 of our IBM SmartCloud Analytics - Log Analysis z/OS Insight Pack offerings.
This release contains a significant number of new capabilities, including domain insights for IBM Information Management System (IMS) and IBM WebSphere MQ for z/OS .
Another major achievement is the ability to run the Analytics engine on Linux on System z . With this, we provide the first IT Log Analytics solution that can be run end-to-end on System z.
The official announcement... [More]
OMEGAMON XE for Messaging v7.3.0 includes several Enhanced 3270 User Interface workspaces with embedded data from other OMEGAMON products, which allow direct access to additional data you need to monitor your MQ applications. It is important to understand that the embedded data feature also allows immediate viewing of z/OS address space data about your queue manager and channel initiator address spaces. Previously, you would have had to hunt through the address spaces listed for an LPAR to find the data you... [More]

The Second in a Series : OMEGAMON XE for DB2 Performance Expert on z/OS development plans to demonstrate, discuss, and solicit feedback on the next set of features and functions in development for the upcoming release. Mark your calendars for October 2, 2014 at 10:00AM Eastern where the development team will focus on:
Navigation improvements planned for the enhanced 3270 UI
Integration enhancements planned for the enhanced 3270 UI .
We look forward to seeing you there.
On z/OS data collected during the OMEGAMON history collection process is stored in the OMEGAMON Persistent Data Store (PDS). The PDS is a set of predefined flat files that are continually re-used. When the active PDS data set becomes full, the PDS data set containing the oldest data will be emptied and initialized for reuse.
The PDS maintenance process is an automated process which should not require intervention by the system administrator. However, there are a number of PDS related MVS modify commands which can be issued... [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... [More]
On z/OS data collected during the OMEGAMON history collection process is stored in the OMEGAMON Persistent Data Store (PDS). In this blog entry we will discuss PDS sizing considerations for the OMEGAMON XE for CICS and the OMEGAMON XE for CICS TG product components.
The PDS is a set of pre-allocated flat files that are re-used on an oldest data basis. When the active PDS data set becomes full, data collection will switch to the next empty PDS file. When there are no more empty PDS data sets, the PDS data set containing the oldest data... [More]
In this blog we will discuss the best practices for configuring Near Term History (NTH) data collection for the OMEGAMON XE for CICS product. The information provided in this blog is applicable for both the OMEGAMON XE for CICS product component and the OMEGAMON XE for CICS TG product component.
The enhanced 3270UI Near Term History feature only requires that history collection be enabled for the desired attribute groups. The NTH reports viewed in the enhanced 3270UI are generated from the same history data that is used for the... [More]
The following is a brief overview of the IBM® DB2® Analytics Accelerator for z/OS® monitoring capabilities with IBM Tivoli® OMEGAMON® XE for DB2 Performance Expert on z/OS – part of the IBM Tivoli Performance Management Suite for z/OS. One would think with queries purportedly running 2000x faster than without an accelerator, who would need to monitor its performance? But just as the first thing all of us techies do after upgrading anything that claims improved performance is to attempt to confirm the... [More]
On September 5, 2014 IBM Tivoli OMEGAMON XE for Messaging for z/OS v7.3.0 became generally available. Besides the near-term history, cross-product embeds and some other cool features, Messaging v7.3.0 also provides updated support for IBM MQ v8.0 features, like:
Automatically discovers and monitors MQ v8 queue managers
Monitors 64-bit Buffer Pools
Incorporates required internal processing changes for SMF Type 115 statistics
Supports 8-byte Log RBAs
Adds more monitoring attributes, for example,... [More]
The SMF type 89 record provides information about product usage on a particular MVS system. A record will be written for products that have registered to indicate that they are running on the system. The SMF type 89 record has two subtypes:
Subtype 1 which contains product usage data
Subtype 2 which contains product state data.
With APAR PM97264 Tivoli Decision Support for z/OS (TDSz) provides exploitation support (from TDSz Version 1.8.1) for both the SMF type 89 subtype 1 and 2 records. The following new data tables... [More]

How Smart is your Infrastructure
Lots of people are talking about Clouds and smarter infrastructure these days. Public cloud, private cloud, hybrid cloud, etc. - lots of noise and hype about the possibilities and the savings that can be realized. Since our software brand is named Cloud and Smarter Infrastructure, let me try to shine a little light on the subject and offer a point of view around our recent announcement of our new Infrastructure Management Suite for z/VM and Linux.
What we've observed in working with several... [More]
