Bpc Toolkit For Load Runner Tire
SAP BPC Performance Testing with LoadRunnerOne of the things in common though is that there are always a number of project people who do not believe SAP needs performance testing, just throw enough SAPs at it and it’ll be OK. Strangely SAP themselves aren’t in this camp, they’ve partnered with HP to ensure that works well with SAP and even resell LoadRunner themselves (with an extended SAP bundle for SAP testing only). I just wonder how many implementations have been hit by the “doesn’t need performance testing, it’s got lots of SAPs” when one of the “z” transactions, or even a small user exit, has been badly coded and performs badly enough to affect the whole system.
Pioneers of SAP BPC 10 Performance Testing using LoadRunnerOur current client does believe in performance testing and for the last few months we’ve been preparing to run our first testing cycle. As we’ve been doing this preparation they threw a new SAP module at us – BPC. This gave a new challenge as we’d never met this module before and it doesn’t use any of the standard SAP interfaces. A quick “Google” didn’t come up with much other than a link to an SAP utility (more on that later) so we could be among the pioneers of performance testing BPC 10 using HP’s LoadRunner!The testing of BPC is being treated as a separate performance testing exercise as it sits on its own server. That’s lead to this series of articles imaginatively called “SAP BPC Performance Testing”.So what is BPC? It’s one of the newer components of SAP and came from an acquisition made by SAP (Business Objects I believe). It stands for Business Planning and Consolidation.
It works off the back of the BI/BW components of SAP and, certainly in our case, sits on a separate server to the main components of SAP. The implementation we’re working with is 400 million rows currently and is expected to grow to just over a billion over the next 3 years before data consolidation kicks in. We’re not testing the BI/BW components so we’re not interested in the impact of the extract and build process from ECC (ERP Central Component); what we want to understand is the BPC usage of the generated data models.There are some interesting aspects to performance testing BPC, the main ones being that the client software is either MS Office based or Flash in the browser. There’s also the minor fact that both pieces of software have some interesting foibles and are, IMHO, distinctly unstable.The Flash interface is fairly straightforward, it just doesn’t always build itself properly.
The pane containing the model information and your activities will sometimes be left blank. A refresh usually fixes it but that causes problems in LoadRunner where you get the start up requests recorded twice.The EPM MS Office interface is an add-in to Word, Excel or PowerPoint, This article is based on using the MS Excel version of the add-in but I would expect they would all work the same way. The add-in adds two extra tabs to your Excel menu bar, ‘EPM (Enterprise Performance Management) Add-in’ and ‘Data Manager’. The EPM tab is used to load reports and input forms from the server into the spread sheet and to upload spread sheet changes back to the server whilst the Data Manager tab is used to submit and monitor background tasks manipulating server side data. If you logged in through the EPM tab then refreshing some reports will, seemingly arbitrarily, log you out which gives you an HTTP 403, unauthorised error. The recorded scripts have shown that it’s not a loss of network connectivity as the commands to perform the log out are recorded.
As a tip: We found that if you log in via the Data Manager tab rather than the EPM tab this happens much less frequently.
What size, type, and rating do you need?Tire sizes are a combination of many different variables: the actual size in width, height and diameter as well as the ratings related to load-carrying capacity and speed-handling ability. Look in your vehicle’s owner’s manual to find the correct tire size, or check the metal tag often found inside the driver’s door jamb, glove-compartment door or fuel hatch. If you find more than one size listed, you should look on the sidewall of your tire instead.How to read the sidewall of a tireThe “P” designates passenger tires.
“LT” designates light-truck tires. Here’s what the numbers indicate:Aspect ratioThis number tells you how tall your tire is. The bigger the number, the taller the tire. And typically, the lower the aspect ratio, the higher performance the tire.
An all-season passenger tire will usually have an aspect ratio between 65 and 80. It is expressed as a percentage of the height divided by the width (75%, 70%, 65%) and is commonly referred to as the tire series (75, 70, 65).Load indexThe load index refers to how much weight a tire can carry.
If your tire has a load index of 82, locate that number on the chart below, and look to the right of it under load (lbs.) to see that it can support 1,047 lbs. At maximum air pressure. Multiply that by four to get your maximum load-carrying capacity. It is not a good idea to install tires with a lower load index than the factory tires that came on your vehicle.Speed ratingThe U.S. Government issues a speed rating for each tire based on how well it reaches and sustains a specific speed. A higher speed rating generally means that the tire will provide better handling.Things to think about when looking at speed ratings:. Downgrading the speed rating of your tires may result in poor handling and unpredictable steering.
If you’re looking for better cornering response, install a higher speed-rated tire on your vehicle. Never mix and match tires with different speed ratings. This will cause serious handling problems.Temperature gradeThis represents a tire’s resistance to heat when tested under controlled test conditions. The grades from highest to lowest are “A,” “B” and “C.” All three grades pass the federal safety standard. “A” is the coolest running tire, “B” runs warmer and “C” just meets the minimum performance requirements (but is by no means unsafe).Traction gradeThis represents the tire’s ability to stop on wet pavement as measured under controlled conditions on asphalt and concrete test services. The grades from highest to lowest are “AA,” “A,” “B” and “C.” These grades do not take into consideration the cornering or turning performance of a tire.Treadwear gradeThis is a comparative rating based on the wear of a tire when tested carefully under controlled conditions.
This tire grade is useful only when comparing tires made by the same manufacturer. For example, a tire graded 300 should have its useful tread last twice as long as a tire graded 150.Another manufacturer may have a different number system, so a different brand tire graded 500 isn’t necessarily better than the 300 of a different brand.Uniform Tire Quality Grading System (UTQGS)The U.S. Government has established the Uniform Tire Quality Grading System (UTQGS) to help you in deciding which tires you want to purchase. Understand that it is a relative comparison system—not a safety rating and not a guarantee that a tire will last for a prescribed number of miles. Under UTQGS, tires are graded by manufacturers in three areas: treadwear, traction and temperature. When, this information can be found on the paper label on the tread as well as on the tire’s sidewall.Ready to buy some tires? You can search our by vehicle or by tire size.
