Once again on the topic of performance testing Business Objects, when executing a benchmark for a web intelligence report with goal being to see how many concurrent users it could support, the following error mesage was being generated in the vuser log: Connection failed. The server has reached the maximum number of simultaneous connections. (Error: RWI [...] I find when testing I need to archive copious amounts of data. Occasionally I need to create a bootable disk image for use in the creation of virtual machines or impromptu test labs. Storing this information and images in the ISO format is quite handy. Most people will already know how to make an ISO image [...] If you have the requirement to manipulate multitudes of input messages / log files / data templates with dynamic variables, you may be left wondering what is the best approach. One could argue in a friendly way for hours about which language is the best to achieve this outcome (almost like pc vs. mac), but [...] I have been working on some template LoadRunner scripts for Business Objects Web Intelligence / Crystal Reports which require good ole fashioned manual correlation. Before writing this post, in the background I have been working on a tool comparison between LoadRunner and my increasing favourite JMeter with a simple (?) scripting exercise that goes through recording, [...] For an internet facing SSH server, it is probably common practice to have sshd listening on a non-standard port. Coupled with key pair authentication, this reduces the profile you present to simple brute force attacks. Connecting to a SSH server on a non standard port is relatively simple: ssh -p username@servername.com You may however need to copy [...] An associate of mine recently wanted a load script that could simulate thousands of UDP packets carrying a custom payload coming from different IP addresses. They were implementing a customised RFID solution that needed to simulate load from a lot of sources (think active RFID tags). There are many different ways you can accomplish this, solutions [...] |
