Hello,

We have our pilot LBI install running on a Win 2003 32 bit 4 processors with 4gig of ram. The server has 20g space available. WebSphere, SQL server 2005 and LBI are all running off one of the drive. We do not have the expertise in house to re-install websphere or LBI.

Any ideas on what would need to change in Websphere and LBI to upgrade to Win 64bit OS so that we could increase the ram? We also need to increase the drive space so that we will not run out of disk space.

I'm not a hardware person so this task is scaring me. Any input will be most appreciated.

Hi Joanna,
You can't upgrade an existing Windows OS to 64-bit--you need to install on a different piece of hardware. Also, while you can install 64-bit SQL Server and Websphere, LBI itself is still a 32-bit application, and requires the 32-bit SQL client. Are you having performance problems, or are you just looking at the disk space issue?

Joanna,

Additionally, although WebSphere and SQL Server can utilize more RAM, we have found a couple items of note:

1. If you allocate more than 1GB of RAM to the Application Server in WAS that is running LBI, WAS will crash and you wont be able to restart it
2. Once the JVM that WAS is running under hits 750MB in memory usage, LBIs performance grinds to almost a dead stop. Simple tasks such as loading a dashboard can take minutes

You probably want to look into scaling of the RAS engine, SmartNotes Engine (if youre on 9.0.3.2) or Verticle Scaling of each of the applications. It all depends on where you are seeing a performance hit.

If hardware is an issue, something as simplistic as installing multiple instances of WAS on the same server and giving each application an independent WAS instance will allow you to utilize more RAM.
