Performance
Fast response times, permanent and reliable, no software breakdowns, punctual completion of the monthly accounts – all these are performance criteria.
When you're talking about performance in relation to SAP systems, you're mostly talking about response times. And that alone is a complex question which usually gets an (overly) simple answer: "More hardware".
When you're talking about performance in relation to SAP systems, you're mostly talking about response times. And that alone is a complex question which usually gets an (overly) simple answer: "More hardware".
The path to good performance takes the following route:
1. An accurate analysis of the current situation
With response times, the first thing that needs to be done is to establish real response times as measured by the IT department compared to the response times "perceived" by the users. As we all know, this problem can quite rightly turn into an emotional debate between IT and users. Users get the feeling they're not understood because they can't document their individual daily experiences with the system. The IT department, on the other hand, points to the figures it has obtained through measurement which allegedly refute the users' complaints.
Using detailed and precise measurements of the system, VMS can contribute considerably to making this debate more objective. In cases like these, it's not a case of hit-lists and average values. We need to ask,
- How dynamically does the system behave?
- Is this behavior predictable for the user?
- In which overall context do unacceptable response times occur?
- If response times get longer, is this due to a resource bottleneck or an encounter
between different user activities?
The VMS Report answers these and other questions in detail. This brings us to the second step.
2. Root Cause Analysis (Aetiology)
Our approach is to use the VMS DataCollector to measure in detail the systems affected. Reference parameters here include the applications and database server, the CPU, memory, the load put on the database by the various users, batch programs and interfaces etc.
The VMS DataCollector records the system behavior in detail and the VMS Report provides the results of the analyses. While only ad-hoc checks are possible in the CCMS, the VMS Report tests statistical similarities in situations from the entire measuring period. So it's a tool for the difficult cases as well!
3. An Accurate Improvement of Performance at Ideal Conditions
By means of precise analysis, VMS can develop ideally coordinated solutions – alterations to configurations, alterations to the DB design or to the client's own programs, alterations to the hardware landscape – and sometimes even more hardware, but in such cases this is customized and targeted.
