When the Sametime meeting server (the classic meeting server for Sametime 8.5x) is under stress, a problem in Microsoft Windows 2003 SP2 described in “TCP connections fail intermittently when both endpoints are on the same computer in Windows Server 2003 SP2 (Article ID: 979230)” can lead to the failure of current meetings, as well as the failure to launch new meetings.

To prevent this situation from affecting the performance of your Sametime server, apply the hotfix Fix307523 as indicated in the Microsoft article linked above.  This hotfix is for Windows 2003 SP2; those customers not running SP2 must install SP2 before applying this hotfix.

Additional information

As noted in the Microsoft article, this problem can occur when an application makes a TCP connection to localhost.  For example, the Sametime server code uses localhost connections for communication between its modules. Under stress, a race condition in the TCP/IP driver in Windows 2003 can orphan these localhost TCP connections, causing applications like Sametime that rely on these connections to fail.  

Restarting the system can provide temporary relief, until such time as stress leads to the next instance of the TCP/IP localhost failure.

After upgrading Adobe 9.x to a later version of 9.x, the client crashes on startup.

Fix details:  SPR# BJGY83MPB6 This issue is fixed in 8.5.2.

At the server console type sh stat server.    There is a server statistic called “Server.Version.Architecture” that indicates if Domino is 64-bit or not.

The server console will display Server name:  Lotus Domino Server (64-bit) at the top of its window

Support for Firefox 4 is introduced in Interim Fix 401.8HF6  for iNotes 8.5.2 Fix Pack 2, which is now available for download from Fix Central. iNotes 8.5.2 Fix Pack 3 will also provide Firefox 4 support. This interim fix can be applied on a Domino server running 8.5.2 Fix Pack 2 or a Domino server running 8.5.2 Fix Pack 2 with a Domino hotfix.  If you are running 8.5.2 Fix Pack 2 with an iNotes hotfix, please contact IBM Support  to request a new iNotes hotfix that combines iNotes IF 401.8HF6 with your existing iNotes hotfix.

Yesterday the users complaim about this and conclude that it’s a domino fault and my fault.

For several years I received this type of complaint. Every time I researched the problem I found problems with DNS. Lack of PTR record, MX record in error and ultimately a lack of SPF record. . It’s not Domino fault! It’s not my fault!

The fault is always (or almost 99%) the network administrators or DNS administrators.

I use the following in my own DNS to avoid problems:

1 – Use the A record pointing to your Domino Server
2 – Create a PTR record for your Domino Server
3- Create a MX record and setup it pointing to the A record of your Domino Server.
4 – Create a SPF record

Today I solved a problem with my wireless home network. My kid have a PS3 and wants to play online.
The signal strength was not too bad (52%) but the PS3 got some network errors and the kid loses the game.
My solution was to buy  another router TP-Link WR941 and link the Linksys WRT54G using WDS.
The problem was that WRT54G doesn’t have support to WDS.  To solve this problem go and change the bios of the WRT54G from the LinkSys to
DD-WRT  http://www.dd-wrt.com/site/index. Look up for your WRT54G version  and follow the instructions.

The WDS setup was easy, just setup the WR941 as usual (basic setup), like next, next and finish. The WR941 was the primary router (gateway to internet), connected to my ADSL and
as a DHCP server for my network, the IP is 192.168.10.1. SSID Springfield2 and  WRT54G IP is 192.168.10.2 SSID Springfield1

The two routers need to operate on the same channel and use the same security settings.

To connect the two routers:

Setup WRT54G as a secondary router.

Put the MAC address of the Wireless  on the WDS setup

Setup WDS on the TP-Link put the MAC address of the WRT54g here.

How To Speed Up WebSphere Portal Server 7 After the Initial Installation

When any version of WebSphere Portal is first installed, there is always a significant load time for each JSP page.   The poor load time is attributed to the fact that each JSP page must be compiled the first time it is accessed.  To avoid the delay, execute the precompile-jsp command.

1. Open a command line and navigate to the following directory:

C:IBMWebSpherewp_profilebin

2. Execute the following command (all on one line)

ConfigEngine.bat precompile-jsp –DwasUser=wasadmin –DWasPassword=wasadmin
