A couple of weeks ago, we launched a new XPages app. Hopefully the first of many. It was very impressive and we got a lot of hits....
...until the server crashed.
Not a big deal. Our server is set to restart automatically, and it was up and running in no time. Then about 1.5 days later we had another crash.
We've decided to tackle this on a few fronts, first of all we're rewriting some parts of the app to be a bit less intense and to take better advantage of the recycler. That's all cutting edge development stuff, so it's really not "me".
On the admin side, I wanted to see if we could release resources a bit. I checked the server close to a crash but there's no indication on the Windows 2003 side of things. Of course, the Notes Logs tell a different story.
HTTP JVM: CLFAD0211E: Exception thrown. For more detailed information, please consult error-log-0.xml located in e:/Lotus/Domino/data/domino/workspace/logs
HTTP JVM: >>>>
HTTP JVM: The XPages runtime engine faced an OutOfMemoryError
HTTP JVM: You can fix this by increasing the value of the HTTPJVMMaxHeapSize variable in notes.ini
HTTP JVM: >>>>
HTTP JVM: Out of memory exception occurred servicing request for: /publicsite/OurNewXpagesDB.xsp - HTTP Code: 500. For more detailed information, please consult error-log-0.xml located in e:/Lotus/Domino/data/domino/workspace/logs
HTTP Web Server: Command Not Handled Exception [/publicsite/OurNewXpagesDB.xsp] Anonymous
HTTP JVM: CLFAD0211E: Exception thrown. For more detailed information, please consult error-log-0.xml located in e:/Lotus/Domino/data/domino/workspace/logs
So, we decided to try a http restart next time these error messages started building up.
It worked!
Doing a TELL HTTP RESTART bought us two more days of uptime.
To Restart or not to Restart?
We looked around and found that our problems weren't as unique as we'd imagined. There are a few people on 8.5 and above (we're currently 8.5.2) who have this problem.
Apparently also, a Tell HTTP Restart flushes memory but doesn't do much for the JVM.
To flush the JVM, we need to think about;
TELL HTTP QUIT
then after a few minutes
LOAD HTTP
or as the guy in the IT Crowd says "have you tried turning it off and on again?"
We'll be doing this until we get our application sorted but the question is; should this be part of our normal nightly routine? Maybe it's good practice to restart your web server's service nightly - especially if you have a cluster which could take the load while the restart occurs.
How to Get your Personal Address Book Data Synching with IBM Notes Traveler and the iPhone/Android
Thu, May 16th 2013 6:42p Gavin Bollard I'm surprised that nobody seems to know how to do this - well, according to my research on the web anyway. So here it is, the instructions for getting your IBM Notes (we don't use the words Lotus Notes anymore) personal address book Synched with your Apple iPhone (and presumably Android too).

How to Figure out When an Extranet User last logged into your Domino Server
Thu, Apr 25th 2013 7:42p Gavin Bollard So, you want to do a bit of spring cleaning in your domino address book and apart from people whose email addresses you use all the time, you want to get rid of people who haven't accessed the server in ages. How do you find out when their last access was? I notice there's a lot of paid solutions on the web but it's functionality that is built into domino already. Here's how to use this feature; Start Domino AdministratorOpen the server that people log intoClick on the tab marked People a [read] Keywords: domino

Getting into IBM Notes 9
Tue, Apr 2nd 2013 10:05p Gavin Bollard I installed the release version of IBM Notes 9 yesterday and I'm happy to say that it works a bit smoother than the beta did. In fact, it's generally quite a nice experience. I've had no crashes so far (unlike my Notes 8 experience where I discovered three different ways to kill the client in less than 3 keystrokes on the first day). The new blue icon is nice and the black panel on the mail looks slick too. As usual, all of our applications work (notes compatibility is generally pretty g [read] Keywords: ibm

How to Disable Phone-based data for the iPhone 4S
Thu, Sep 20th 2012 5:22p Gavin Bollard Why would you do this anyway? With the mobile data connection disabled, the iPhone can still hook into wireless networks, including those at home, in shopping centres and hotels, at McDonalds and Starbucks, on public transport and at the office to surf the internet and to receive data. It just won't be able to access data where there is either no internet wi-fi connection or where you haven't set it up. As a means of keeping mobile costs down however, the wi-fi option is certainly better th [read] Keywords: blogger

Adjusting our Word VBA Macros for Office 2010 (64 bit)
Tue, Feb 28th 2012 5:44p Gavin Bollard We've had it easy these last few years. You could just upgrade Microsoft Office and not have to worry about file compatibility or about your macros not working. I was just beginning to relax. Unfortunately Microsoft never relaxes and the latest "innovations" extend past the annoying ribbon interface (I've been using it for over a year and I still consider it annoying) to clobber both file formats and macros.

How to Create an Auto-Response Mail Message in Lotus Notes 8.5.3+
Tue, Feb 21st 2012 6:43p Gavin Bollard Why would you do this? Suppose that you have an externally accessible generic email address for your company; support@mycompany.com or info@mycompany.com. You might expose this to the web and allow people to send messages to you. Setting up an auto-response email will tell the senders that their message reached its destination and that it will be dealt with accordingly. It's also good practice to include links to FAQs or other useful information. Why 8.5.3 The techniques we'll be using he [read] Keywords: agent
