Hello all,

ITSM V7 installed, I have a big problem of performance of the Mid-Tiers unseen with the V6.3.

In fact the first time we load a form it takes between 30 sec and 1 minutes !
a lot of proc ressource are used ~30%

I have seen a file call prefetchconfig.xml which can be update, I don't know exactly who to configure this file to get better performances.

<?xml version="1.0" encoding="UTF-8" ?>
- <midtier-prefetch-config xmlns="http://www.bmc.com/remedy/midtier/700">
<prefetch-user>
<user-name>Demo</user-name>
<locale>en_US</locale>
<prefetch-server>
<server-name>MYSERVER_DNS_NAME</server-name>
</prefetch-server>
</prefetch-user>
</midtier-prefetch-config>

I can enter too, Application Name and Form name, a small doc specifies that if an Application Name is given all forms under this application is activated in prefetch !

But when we used the basic ITSM installation there is no specific name for the defaut application ???

An idea ?

Tsys,

You can configure this file first by putting your server-name between <server-name> </server-name>.
Next you give application name:

here an example :

<midtier-prefetch-config xmlns="http://www.bmc.com/remedy/midtier/700">

<prefetch-user>

<user-name>Demo</user-name>

<locale>en_US</locale>

<prefetch-server>

<server-name>Remedy-prod</server-name>

<prefetch-app>
<app-name>Home Page</app-name>
</prefetch-app>
<prefetch-app>
<app-name>AR System Administration</app-name>
</prefetch-app>
<prefetch-app>
<app-name>Remedy Incident Management</app-name>
</prefetch-app>
<prefetch-app>
<app-name>Remedy Problem Management</app-name>
</prefetch-app>
<prefetch-app>
<app-name>Remedy Financial Management</app-name>
</prefetch-app>
<prefetch-app>
<app-name>BMC:Atrium CMDB</app-name>
</prefetch-app>
<prefetch-app>
<app-name>Remedy Asset Inventory</app-name>
</prefetch-app>

</prefetch-server>

</prefetch-user>

</midtier-prefetch-config>


When you restart the webserver, the first user should have a long time to access the forms. this is a normal thing. once the server hasn't cache all his pages, it should take some times to browse it (depending your hardware and software configuration).
To improve the performance, you can tune your midtier configuration.

Hi,

Try to increase your Xms and Xmx java parameters for better performances.
