Unisys Libra Systems : Get the most from your Libra. | ||
Resource Guidance Solutions (RGS) is a complete Capacity Management product for Unisys Libra systems and has been our core business since being established in 1988. On this particular page, a specific module that can be used for analysing Unisys Libra systems is discussed. Users of Libra 590/595 systems should refer to Metered Systems for additional information pertinent to this particular Libra system. The RGS Product consists of an Agent for collecting data and a PC software package. The agent uses standard documented system calls for retrieving the data and is a very low overhead (typically < 1%). Running 24 * 7 * 365, the agent creates just 1 file per day which contains all of the information required by the PC application to produce capacity reports / analyse issues further. The whole process of collecting data, importing it into the PC product and creating reports is fully automated to minimise user involvement. In fact, the person reviewing the reports does not need to be a Unisys Libra expert to decide if any further action is required. Computer Performance International is a Unisys Approved ISV. However, we are fully independent. Our only obligation is to our clients, ensuring they minimise their costs while delivering a quality service. | ||

| RGS Unisys Libra Methodology | ||
Our methodology for managing Unisys Libra systems takes a top down approach and focuses specifically on online and batch processing capacity. If more detailed information is required, the RGS product can be used to browse information such as workload, program, unit (Pack, ODT, Printers etc), transaction and system information. As part of any regular system review we would recommend Unisys Libra users use the System Summary Report as an initial view of how the system has been performing – this focuses on key performance metrics and allows decisions to be made rapidly concerning the state of the system(s). In the following example you will see that the report contains data for just a single system over a period of time. Perhaps most importantly, this report allows us to look down the column titled “Online Utilisation” and make judgement regarding online utilisation. If all is okay then there’s little to worry about, but if there is something of concern, you’ll see it and later you'll see that action can be taken to discover why the problem occurred!

Many of our users keep years worth of data which can be used to plot trends in online utilisation, transaction response time SLA's, transaction volumes, disk occupancy etc. Once armed with a sufficient amount of data other users have used this information to build forecasts of future levels of online utlisation, transaction/business volumes etc. As mentioned earlier, we have to consider Unisys Libra systems from both the online and batch processing perspectives. Both are very different workloads and so we have to analyse them differently. In the example below, you will see a report that shows the flow of “critical” batch processing with total CPU utilisation mapped over the top.
Click on the picture for the full image. This is a very powerful visual report that you can use to quickly identify any gaps in critical batch processing and make immediate savings if your month end batch processing over runs! Not everything in life is so simple though! Using information in the report you can start focusing your attentions on the “big hitters” and really begin to make an impact on reducing those batch elapsed times! What about those daily batch processing runs? How long are they running for? how close to the start of online are they finishing? | ||

If something has been highlighted in the Summary Report or Batch Gantt Report and further action is required it will be necessary to delve deeper into the product using the browse capability. This is where you will find all of the information required to answer any questions that may have arisen from the reports. There are a number of pieces of information that can be viewed in browse mode. They are: Capacity, Workload, Program, Transaction, Unit and System. Click here to see a slideshow presentation. You may have noticed that all of the data presented in the slideshow was organised into 1 hour interval slices. This is a default for all data in RG Solutions but can easily be changed. Interval slices as low as 10 minutes can be selected if desired. In addition, data can also be viewed over an entire 24 hour period, it can be divided into "shifts" or split out logically e.g program data might be split by usercode. Using the powerful sort, search and filter capabilities which are built in to RGS you can quickly extract information from the database and begin remedial action. If needed any data found in RGS can be extracted and passed off. A common example is where a problem program has been profiled and the information can be passed to a developer. RGS For Libra Systems In Action Since Computer Performance International was established in 1988, we have helped many clients from UFSS users to those with “hand knitted” applications to improve the performance of their Unisys systems. In some cases, what was considered impossible has been achieved! Some of the projects that we have been involved with are:
In summary, using RGS gives you full business control of your Unisys Libra systems, allowing you to manage your resources cost effectively. You can provide for the impact of new services before they are implemented. This is backed by CPI’s considerable technical and management expertise, which is second to none in the business. By working with CPI, all our clients typically reduce their IT costs by at least 15%. Tel: +44 (0) 1753 890808 Email: mail@cpiuk.com | ||
