Extreme Stress Testing a Domino Server | BlogEarlier this year I talked about OutOfMemory Java Exceptions I was experiencing. Now I find myself back in the position of writing Java Agents that could potentially leak memory and I'm still really non-the-wiser as to whether I'm clearing up after myself properly in my code. The code I've written generates PDFs and both emails them and attaches to document. There are OutputStream, InputStreams, ByteArrays, Streams, MimeEntities not to mention all the Domino objects being used. I've done my best to close, flush and recycle everything. But I'm still paranoid. I don't want to be responsible for killing no server. Stressing OutSo, I've been stress testing the server. Big time. To do this I added a Page in the database and threw together the tool you see below, which lets me tell it which URL to stress test and when I press " Go" it makes a request for that URL once every second until I tell it to stop.
The output you see in the textarea is the JSON I got the Agent to return. The Agent does it's usual business of creating the PDF and storing in a document. It then returns some information about the JVM's memory usage. To do this the Agent ends with this code: out.println("Content-Type: text/plain"); out.println(""); out.println("{\"memory\":"+ "{\"total\":"+Long.toString(Runtime.getRuntime().totalMemory())+ ",\"free\":"+Long.toString(Runtime.getRuntime().freeMemory())+"}}"); I then left the Ajax code running and calling the code once a second. Overnight! By the morning it had made 45,000 calls. Total Memory had fallen from 30.8MB to 18.4MB. The "free" memory had fallen from a range of between 19mb to 400kb to a range of between 4.5mb to 500kb!! I then left it running overnight again the next night (with no server respite or restarts). The next day the total memory had risen back to 25MB! Odd, huh? So, although it looks like the total amount of memory available to the JVM fell overnight the first night, the server managed to regain some of it the next night. The server is a fairly low-spec VM with 1GB of RAM running on Windows 2003.
I've been keeping an eye on the amount of memory the nhttp process is using up and it seems fairly consistent and not about to pop. Heading For a FallIs what I'm seeing typical and expected? Or does the gradual fall in total amount of memory the JVM has mean that, at some point, it's going to break? Anybody interested in this "tool". I'm not sure whether to make it more configurable and add charts etc. There are lots of powerful web server stress testing software out there, but they're all overkill for what I wanted.
2. Quick Domino Tip: Dual-Purpose Agents | BlogWhen developing I always try to use as few design elements as possible. It's a thing of mine, although surely not uncommon? Last week I needed to do some server-side validation. First I wanted to validate in "real time" using Ajax to give the user feedback as they filled out the form and then, second, I wanted to validate again when the form was submitted (you should always validate on save). I did something I'd never done before and which saved adding two new elements to do the same job; I used an Agent that works out whether it's being called directly via a URL call or whether it's being ran as part of the form's WQS event. Here's HowIt works in Java or LotusScript, but here's the concept as seen in Java: import java.io.PrintWriter; import lotus.domino.*; public class JavaAgent extends AgentBase { public void NotesMain() { try { Session session = getSession(); AgentContext agentContext = session.getAgentContext(); Document docContext = agentContext.getDocumentContext(); PrintWriter out = getAgentOutput(); //Run code common to both agent calls here. if (docContext.getItemValueString("Query_String").toLowerCase().indexOf("openagent")==0){ //Run code specific to Ajax calls (and return some JSON) out.println("content-type: text/plain"); out.println("{\"valid\":true}"); } else { //Run code only needed for WQS docContext.replaceItemValue("Valid", "1"); } } catch(Exception e) { e.printStackTrace(); } } } As you can see it works out if it's an Ajax call or not based on the Query String. Yes, even agents ran directly via the URL have a document context! As it's a WQS agent it needs to be set to run on no documents and from the agent list. You can have your Ajax call the agent directly using the bracketed notation like this: http://www.codestore.net/user.nsf/(ValidateCellNumber)?OpenAgent You can also run the same agent in the Form's WQS:
One less Agent to maintain! At some point I'll include this trick in a working Cell Phone Validator demo I plan on building in to Dext. GotchaIt's not perfect, as it relies on the agent being called with it's full formal URL of ?OpenAgent and not just a simple ?Open. But hey, that's a trade-off I'm willing to make.
