in Onboard Administrator is refreshed. The time taken could be lesser than this at times, but 60
seconds is a conservative time interval which could be relied upon.
In HP SIM 7.3, upon reception of Blade insertion trap from Onboard Administrator, rather than
immediately kicking off reidentification HP SIM waits for a configurable interval of time and then
initiates re identification. The configurable parameter is bladeInsertDiscoveryWaitTime
This parameter is a global setting and is currently configured to 60 seconds. For all practical
purposes this interval is sufficient. However if there is a case due to slow responding systems, if
this interval is found to be insufficient, then you can change the default value through the command
line interface: go to
-s bladeInsertDiscoveryWaitTime=120
, where 120 represents the new value in seconds.

If you are using a Firefox browser, you should avoid remaining on the Task Results page for an
extended period of time. If you notice the browser becoming sluggish while viewing the Task
Results page, you should sign out of HP SIM to allow the browser to release memory. You can
then sign back in.

My Browser is displaying an error message Communication with the HP SIM server
has been lost
.
Solution: The HP SIM portal relies on the CMS to respond quickly to all requests.
•
If the CMS is slow to respond to one request, browser performance can fall significantly during
that time.
•
If the CMS is slow to respond to two requests, the browser appears to lock up completely
during subsequent interaction; the browser does not send additional requests until there are
fewer than two outstanding requests.
•
If four sequential ping-like requests takes more than 30 seconds each to complete, either due
to request queuing or slow CMS response, the browser displays the message, Communication
with the HP SIM server has been lost
, even though the CMS might still be
responsive to other browser sessions.
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 to 100 milliseconds, which is nearly instantaneous. Requests that involve database
queries or secondary network communication might 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 taking an unexpectedly long time.
•
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.
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:
