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.
The Tivoli System Automation for z/OS (SA z/OS) Beta program is in full swing, with some very active participants. This week, over 70 posts were made in the Forum. All of this will go to improve the product.
We still have several spaces on the program, which will run for a few more months. See this blog post for a description of the current product and this Statement of Direction ( SOD ) to learn about the future trends of the product. SA z/OS is keeping pace with the latest IBM technology. Extract from the SOD: IBM Tivoli System... [More]
Hi All, The solution reported at the following link (it's from the "integration scenarios" wiki) can be useful for all TWS for z/OS admins using the TEP integration: http://www.ibm.com/developerworks/wikis/x/dQX8Cw That link has an attached document describing how to implement a solution entirely based on a TEP feature (the link to ) allowing to create a "launch in contest" link between different table spaces. In particular it describes how to create a link between the ALERT table space and the JOB table space. This makes... [More]
How can I reduce the time period on the Response Time History panel? The option or value you want to specify: Start time and end time for the Today’s Response Time display The parameter to use: TIME_SLOT The location in the file for the parameter: RESPONSE_TIME_COLLECTION The time slots divide the previous 24 hours into a maximum of 48 user-defined intervals to display response time history. The time slot parameters must be defined in the global data area module, as described in the OMEGAMON II for CICS Customization Guide . Global... [More]
