Category domino jvm crash
Hi all,

i'm back on my long problem about the JVM crashing the server (http://lotus.bluegeek.fr/web/bluegeek.nsf/d6plinks/BMAI-7PDE76)

I decided to reinstall windows server 2003 R2 +SP2 and then domino 8.5.1 +LP FR.

so i retested to enable JVM and boot domino and...crash !

as always: few informations on the nsd log, but one time i got this:

Ok, an access violation, but where, with which software ?

Even IBM support does not found.

so i googled all taht again to find that my server (dedibox V1) run on a Via C7 processor with padlock.

I found something interesting when i've tried to start the server with the controller and the java console.

the server did not start, but three new files appeared in the data diretory.

One of this file (javacore.xxxxxxx....txt) contain that:

2XHCPUS        Processors -
3XHCPUARCH       Architecture   : x86
3XHNUMCPUS       How Many       : 1
3XHNUMASUP       NUMA is either not supported or has been disabled by user

what is NUMA ?

well, google answer me that is the Non Uniform Memory Access and that is a part of AMD multi core processors.
Nothing to do with me as the C7 has one core.

digging more deeply, i ended to find that: http://www-01.ibm.com/support/docview.wss?uid=swg21267793

where the article talk about the fact that on some hardware where numa is enabled, domino could crash and that we need to enable the /usepmtimer on the boot.ini of windows to use the he Windows operating system to use the PM_TIMER, rather than the Time Stamp Counter.

I was just wondering what's the impact on my domino server date if i try this option ?

Category domino notes 8.5.1
After all, the so called Domino 8.5.1 and lotus notes 8.5.1 are available in french from passport advantage. In fact, i were able to download Lotus_Designer_Adm851_Win_FR_CZ90QFR.exe, traveler 8.5.1 multilingual and even lots client 8.5.1 fr alone, but impossbile to download The French Language Pack for domino 8.5.1, download director saying me the file does not exists on the server (even http download does not work).

IBM, please, do some thing on your website:
1. test files you put on it.
2. please, please, please, do something to make it a little faster, please ! 10 minutes just to search for a file...a bit long to me.

i've just finished to install notes, admin and designer 8.5.1 and here is what i can say:

8.5.1 does not really start faster than 8.5. I can not see where people have seen more speed during starting (ho, and the installation just take one hour or so...)
icons are now staying at their place. (just need to re install notesfix and docinfo to get the icons.)
i can change the unread color.

Designer: i'm in love with lotusscript editor for coloring.

so, i'm just searching for a good package of

IBM Lotus Domino 8.5.1 Language Pack for Windows 2003, 2008 and IBM Power Systems French(CZ93UFR) as the file can not be downloaded via passport advantage.

ho, and more to come on Lotus protector i'm testing (i give it a try) for a week now.

Category domino pop3
Hi all.

Last week, i decided to take a look at an old problem on my 6.5.4 fp3 domino.

Some time ago, i needed to enable internet site document to play with web site.

Of course, we use smtp and pop3 on this server, so i needed to create internet site documents for smtp and pop3.

If smtp is running well with internet site document enabled, the pop3 server refuse to answer my requests, saying: "Connection attempted on <Organisation>, but not configured in POP3 Internet Site Document"

This problem was old and i found some new things last week:

http://www-01.ibm.com/support/docview.wss?uid=swg21199698 and http://chris-linfoot.net/d6plinks/CWLT-6EVC8Z  show me the way.

In fact, i were not using ip address in the internet site document for pop3, so i checked that and put the local ip address of my server in it.

Then i restarted the pop3 task and the http task to see the result.

And ...Magic...pop3 started to answer my requests.

But today, after the sever restarted during the week end, pop3 still say:"Connection attempted on <Organisation>, but not configured in POP3 Internet Site Document"

All i can do now is to disable the loading of internet site documents on the default document server.

i opened a pmr to lotus as i do not know what to do next.

Edit and solution with read more...

Category apache domino web attack

If you have not heard about SlowLoris and other HTTP DOS tools, it's time to listen

All version of Apache server are vulnerable by this http dos attack.

very simple to experiment, just a few commands to get the tool and test against any webserver.

For my first test, i have attacked my webserver, a simple apache2 server, listening on the default 80 port.

3 seconds later, the site became unavailable.

The only informations i found against this is:
Mod_antiloris which is a mod for apache. --> this was not working for me, maybe a bad config.
A reverse proxy (not apache based of course) in front of apache. --> the only real solution for the moment, plus it can help to create High availaible service.

After installing the reverse proxy, i decided to test slowloris against my domino server.
3 seconds later, the domino web server became very long to answer but continue to serve page (very slowly)


So i can advice you to check you apache and domino server and put a reverse proxy in front of them.
more info here: http://ha.ckers.org/blog/20090617/slowloris-http-dos/

Category 8.5 domino performances

We, at work, are going to buy a new server to upgrade our corporate domino server.

This server is used for mails, workflow databases, developpement, and soon i hope, traveler and sametime (lite).

So we need a server with great IO if possible and i want it to be virtualizable ready.

I check IBM site and discuss with a resseler and it seems that a x3500 could be the server we need.

Bi quad Core, 12 GB of ram, 3*300Go sas at 15K.

The unknown for the moment is the licence price for VmWare ESX and some windows 2003.

I'm waiting for these informations to take a decision and i am starting to think to go to another resseler who maybe does not do IBM at all...

Any advice on the hardware needed ?

Category domino 8.5 http crash jvm crash

Hi all,

Here we are: the blog is now running under domino 8.5.

all went fine except for this f......g jvm that is crashing the server if i enable it.

for the moment, the jvm is disable in notes.ini:

httpdisablejvm=1

Even specialists at IBM do not find where the problem is. (After so many IBM_TECHNICAL_SUPPORT folder sent, with all the possibles logs...)

i've upgraded domino 8.0.1 to 8.0.2, to fp1, to 8.5 and the problem still occurs.

i've even do a clean install of a 8.0.2 server, without any of my databases, like a new server...and the problem is still present.

Again, nothing special is running on this server: no BES, no QuickR, no Sametime, nothing but just using web sites...

Category domino http

At last, i decided to upgrade the domino utility 7.0.2 fp3 to domino 8.0.2.

If the installation process is very simple (no problem at all during upgrade), the first boot of the server is more complicated for the nHTTP task...

Hi all,

You know sometimes it's too hard to upgrade a domino server.

In fact, i need to upgrade from a 6.5.4 FP1 to a 8.0.1 and that seems to easy for many of you.

But in my case, many things need to be done before any domino upgrade.

Hi all, ( me in fact )

I have not yet upgraded to domino 8.0.1 (from 6.5.4 fp2) whereas i've planned to do it before the end of March.

Many reason to that:

Category Domino

La migration d'un serveur Domino est toujours quelque chose qui me fait peur.

Je prend toujours mes précautions (ie: sauvegarde des répertoires domino avec toutes les bases, et même la base de registre).

Cependant, je vais prochainement lancer la migration de mon serveur domino 6.5.4 FP2 vers la version 8.0.1 (dès sa sortie en français le 7 mars 2008) et je sais déjà que les choses ne seront pas aussi simple que par le passé (V5 à V6).

En effet, il faut penser à bien plus de choses et faire attention maintenant à la version du serveur qui héberge domino.

Category web domino

Me voici de retour avec mon problème de fichiers attachés à un document lotus notes, crées à partir d'un formulaire sur le web.
Dans un précédent billet, je vous indiquais comment, en piquant divers code à droite et à gauche, nous pouvions présenter les attachements notes, joliment sur le web (cf billet http://lotus.bluegeek.fr/web/bluegeek.nsf/d6plinks/ADMN-77ZH4W).

Et bien ce billet a pour but de vous montrer que dans le monde domino/web, rien n'est simple (ho, et loin de là...).
Si d'un côté les fichiers attachés depuis notes s'affichent correctement dans leur format web, il en est tout autrement des fichiers attachés depuis une interface web et vus par un client notes...

Ha, lorsqu'il faut passer sa superbe base sur le web, c'est toute une histoire.

Ma petite base de gestion des employés et des documents fonctionne à merveille en version notes, avec un cadre à gauche pour inclure un plan qui ouvre les masques sur la partie de droite.

Lors de la conversion de cette base en format web, outre la création de masques dédiés au web, je me suis trouvé confronté à un problème assez génant: comment se passer des cadres mais garder un joli plan (un menu quoi) qui ouvrirait chaque masque ou vue (et leur masque $$templatedefault qui va bien avec) dans une partie droite de l'écran.

Ca paraît incroyable...

Lotus Domino 8 ferait moins d'accès disques que domino 7, en utilisant bien sûr les templates 8.
