1)What is the role of Memory utilisation and process utilisation while dealing with loadrunner?
I mean to ask can we know on an application by using loadrunner how the memory utilisation is effected and process utilisation is effected when large number of users are using application.
What exactly memory utilisation and process utilisation means?
2)How do you solve synchronisation problems using loadrunner?Is there any Synchronisation point funda like in winrunner ?
3)Regarding production environment ,What does the term Clustered environment means in hardware?
3)Regarding data base -Bulky the database,more the latency.What does the latency means?
Conductiing first set of test on a 50ksized db then a 100k sized db and so forth.What does this sentence mean?
4)Regarding reports - loadrunner detailed reports for engineering department.What does it mean?
5)Regarding metric collection- Some basic metrics can be collected like
cpu utilisation,perpage size,configuration details,testbed details,number of process running on server,memory details,total hits,hit.second and percentage of failed transactions.From where we can collect the data for this.
And after execution of script how to compare the expected with actual?I mean to ask how can we see the details above said in the analyser?
Thanks and Regards
Re: CPU utilisation
1)Yes, by looking at the data provided by monitoring the server(s)
3)clustering: Connecting two or more computers together in such a way that they behave like a single computer. Clustering is used for parallel processing, load balancing and fault tolerance.
Clustering is a popular strategy for implementing parallel processing applications because it enables companies to leverage the investment already made in PCs and workstations. In addition, it's relatively easy to add new CPUs simply by adding a new PC to the network.
Microsoft's clustering solution for Windows NT systems is called MSCS.
(1) In general, the period of time that one component in a system is spinning its wheels waiting for another component. Latency, therefore, is wasted time. For example, in accessing data on a disk, latency is defined as the time it takes to position the proper sector under the read/write head.
(2) In networking, the amount of time it takes a packet to travel from source to destination. Together, latency and bandwidth define the speed and capacity of a network.
Tip: Read the manual, take the course and study.
Re: CPU utilisation
5)You need to have Admn rights on your webserver to monitor CPU Utilization, Resources.
