There are situations that may result in particularly slow response times. For example:
• Viewing large collections of systems or events.
• Specific/custom database queries taking an unexpectedly long time.
• Many users simultaneously accessing a shared resource, such as the database.
Solution: The maximum number of server connections can be increased in both Internet Explorer and Firefox.
The default number of connections is two. Though you can increase this number into the hundreds, it’s
recommended not to exceed ten. For more information, see:
• Internet Explorer: http://support.microsoft.com/kb/282402/
• Firefox: http://kb.mozillazine.org/Network.http.max-persistent-connections-per-server
-------------------------------------------------------------
By default, web browsers are limited to two simultaneous connections to a single web server. If two requests
are outstanding, any additional requests wait until one of the current connections completes. This is by design
and is in agreement with the HTTP 1.1 specification. The HP SIM UI generates many requests, many of them
simultaneously. The HP SIM portal relies on the CMS to respond quickly to all requests. On a LAN, the
browser receives a CMS response to most requests within 10–100 milliseconds, which is nearly instantaneous.
Requests that involve database queries or secondary network communication may take a few seconds to
respond. The following situations might result in particularly slow response times:
• Viewing large collections of systems or events.
• Specific or custom database queries.
• Many users simultaneously accessing a shared resource, such as the database.
• Pages (for example, System Properties) that retrieve data using WBEM or SNMP and display the results,
especially when the requests are destined to time out.
To resolve this issue for the Microsoft Internet Explorer and Mozilla Firefox web browsers, increase the
maximum number of server connections to the web server. The default number of connections is two.
IMPORTANT:
For more information about increasing the number of server connections, see the following sources:

When browsing to HP SIM using Microsoft Internet Explorer 6.0.3790.0 on Windows 2003, the billboard
in lower corner of the Home page is blank.
To correct this issue, enable Play Animations in Web Pages in Internet Explorer. To access this, select
Tools→Internet Options→Advanced, and then select Play Animations in Web Pages under the
Multimedia section.

If you receive a Page Not Found browser error when launching PMP tools from within HP SIM, the CMS
name link might not have resolved correctly on the network. Note the name being used in the browser
window, and verify that the name resolves on the network and that it is not being affected by any proxy
settings in the browser.

When you try to browse to the System Management Homepage (SMH) on the same Linux system that HP
SIM is installed, you might receive multiple browser warning messages.
1. Open a terminal window.
2. At the command prompt, enter:
cp /etc/opt/hp/sslshare/* /opt/hp/sslshare
