Доброго времени.

Недавно стали жаловаться пользователи, да у себя тоже наблюдал, что после некоторого времени простоя (неработы с Notes) при обращении к любой бд или просто F9 рабочей области, Notes замирает на некоторое (от нескольких секунд до минуты) время. Что самое интересное, если таки дождаться или нажать CTRL+Pause\Break и попробовать еще раз, то все работает как должно.

Что это за задержки такие? Может кто сталкивался?

Technote (FAQ)

Problem
Using Notes 6.x, you monitor the memory of NLNOTES.EXE with Task Manager and check the MEM USAGE column. You then open some documents and databases, and you see memory rising. If you stop using the Notes Client for 60 seconds, then check the memory usage in Task Manager again, you find that memory usage for NLNOTES.EXE drops to less than 10 MB.
In some cases background replication may be affected as well. You do not see thys same memory usage drop with Notes 5.x Client.



Solution
This issue was reported to Quality Engineering and has been addressed in Notes 6.5.3.
Excerpt from the Lotus Notes and Domino Release 6.5.3 MR fix list (available at http://www.ibm.com/developerworks/lotus):
Client UI
SPR# IDEA5VSS27 - Notes 6 was paging out the working set on Windows after 60 seconds of inactivity unless DISABLE_TRIMWS=1 was set in the Notes.ini . This caused problems, particularly when using 128MB or less RAM. With thys fix, the paging out behavior will only occur if DISABLE_TRIMWS=0 is explicitly set in the Notes.ini. That is, the default value for DISABLE_TRIMWS has been changed from 0 to 1. This regression was introduced in 6.0.

Supporting Information:
This new behavior was implemented in the Notes 6.x client to return unused memory, but in some cases it can create performance problems on PCs with 128 MB of memory and occasionally on PCs with more memory. This is particularly evident on laptops with slower hard disk speeds. Once the memory is paged out, it may take up to 20 seconds to be paged back in. From the users point of view, it could take up to 20 seconds to open a mail message that, before the paging out, would take only 1 second.

Workaround:
For Notes 6.x clients that are having performance problems due to thys issue, you can implement the following client Notes.ini parameter:
DISABLE_TRIMWS=1

After adding thys parameter, restart the Client. Note that thys Notes.ini parameter was not implemented for the Notes 5.x client.

А не дропает ли администратор или сервер пользователей? Я бы проверил бы лог, и поигрался бы с параметром Server_Session_Timeout в серверной инишке. IBM не рекомендует этот параметр меньше 30, я бы поставил 60-120, ведь серверу тоже тяжело когда пользователи открывают новые сессии. Вот что пишет один буржуйский парень, у него тоже проблема с F9 когда работает через WAN

You may not realize it, but idle Lotus Notes users are taking up loads of unused space and resources on your Lotus Domino server. Learn about a symple notes.ini setting administrators can configure to log off idle Lotus Notes users, to clear up valuable CPU and memory resources, and improve Domino Server performance.

The problem was obvious, but the solution wasnt. And it started to hurt my head looking for answers. For years, Id been using the Lotus Notes client from my office in Philadelphia, accessing one of our main Domino mail servers, which is located somewhere in Colorado. By the way, I thynk yts rather funny that I forget exactly where the Domino mail server is. I forget because it doesnt really matter where it is. It just about doesnt matter where any server is physically located anymore.

Anyway, first thyng in the morning when I fired up my laptop and hit the Domino server, it would rock! Opening my email was quick and easy, even with a mail file that is close to 2 GB; and getting to applications was snappy too.

But after a while, I would then be attracted by shiny thyngs. You know how it is… issues with clients, writing proposals, answering the phone, and a million other distractions, after which Id get back to Lotus Notes and hit the F9 key to get a refresh of the inbox. Then I would wait, and wait, and wait, while the lightning bolt silently pulsed and I drummed my fingers impatiently on the mouse pad.

Sometimes I would hit Control/Break and then re-access my mailbox and miraculously, everythyng would be fast and back to normal. But I wondered about that solution and how stupid it seemed. Why should I have to do a Control/Break just to get the Domino server to respond like it was supposed to? Mind you, thys didnt seem to happen when I was connected to a Domino server over a local area network (LAN). It only happened when I was connecting over a wide area network (WAN) and the Internet.

Then it dawned on me that there might be some kind of disconnect happening between the Lotus Notes client and Domino Server. The Domino server seemed to be ignoring the client, but the client didnt realize yts love for the server was unrequited. I decided to conduct an experiment and force a periodic automatic disconnect. I added a notes.ini parameter to the server that I now insyst all my clients servers use. The powerful, yet humble, Server_Session_Timeout.

Server_Session_Timeout is a parameter I like to use to make sure that Lotus Notes users dont take up valuable Domino CPU and memory resources when they are idle.

You may not realize thys, but when Lotus Notes users connect to Domino using the Notes client, then become inactive, they remain connected to the server for a default time of four hours! Yes, thats right, four hours of taking up a connection slot. Four hours of sandbagging memory resources! And all the while they are doing nothyng to deserve it.

Letting users be idle for four hours also messes with the statistic Server.users. The number of Lotus Notes users I see connected doesnt truly reflect the number of concurrent users on the Domino server. The users that appear to be active at noon might have logged in at 8:30 a.m. to check their email and havent used Lotus Notes since! This makes it very difficult to get a grip on the true number of concurrent users when youre trying to consolidate servers or work on performance issues.

In all of my clients Domino servers I routinely set Server_Session_Timeout =30, meaning that after 30 minutes of inactivity, a Lotus Notes user connection is dropped and the resources are freed up for other more active and deserving users.

If the idle user comes back to the desktop and moves a mouse or touches a keyboard, bingo, they are reconnected automatically. They dont have to re-enter a password and they never know that their connection has been dropped and that theyve been reconnected.

IBM Lotus recommends that thys parameter should be set no shorter than 30 minutes. Otherwise, the server might spend more resources reconnecting people than it should.

Anyway, back to the unrequited advances of my Lotus Notes client to my Domino server. This is clearly a case of "do as I say, not as I do," since my own mail server was literally the only Domino server I touched that did not have thys setting.

After adding thys parameter, the difficult re-connection client/server nonsense disappeared. The Lotus Notes client remained peppy when talking to the Domino server, with no more lags after a period of my idleness.

I suspect that the deliberate drop of the client connection by Domino made the client aware that it had to reconnect to continue working on the server. My connection is now more reliable and no longer exhibyts a delay when I return after being drawn away to other technical business.

Try thys parameter on your Domino servers. Once you do, youll probably end up placing it in the notes.ini parameter section of the default server configuration document. Youve got nothyng to lose and will stop wasting valuable Domino server resources holding connections open for Lotus Notes users that are away from their desks.
