HP Systems Insight Manager 7.3 Installation and Configuration Guide for HP-UX

Tuning HP SIM (Optional)
Using SAM or the HP-UX Kernel Configuration tool (kcweb) or kctune, complete the following
optional manual parameter adjustments, if needed.
• Set the dbc_max_pct kernel parameter. This is the percentage of physical memory that can
be dynamically allocated for the data buffer cache. It defaults to 50%, which is usually too
high. Set this variable to the percentage of your system physical memory that equals
approximately 200 MB. For example, a server with 1 GB of RAM should have this value set
at 20%. Refer to the dbc_max_pct man page for additional details in tuning this parameter.
NOTE: This value cannot be less than dbc_min_pct, which cannot be less than 1%. For
more information, see the dbc_max_pct man page for additional details.
NOTE: For HP-UX 11i v2 (September 2004 or later) (B. 11 .23), these parameters are
dynamic, when you modify the parameters, you do not have to reboot the system.
NOTE: The kernel tunable parameter dbc_max_pct is obsolete for HP-UX 11i v3.
Next steps
Install and configure the required Management software on the systems that will be managed by
the CMS. For more information, see “Setting up managed systems” (page 30). Next, complete the
initial setup of HP SIM which involves using the First Time Wizard to perform the initial configuration
of HP SIM Central Management Server as well as steps for setting up managed systems. For details,
see “Configuring Systems Insight Manager” (page 33).
HP SIM is now installed and initialized on the CMS. Start the HP SIM GUI using Firefox at
http://<IP_Address>:280/.
NOTE: The Systems Insight Manager Registration window and First Time Wizard appear when
a user with full configuration rights logs in to HP SIM for the first time. Follow the onscreen instructions
to register HP SIM or click Register Later to register at another time. If your HP SIM system is not
connected to the internet, you can go to a system that has internet access and navigate to http://
h20293.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=HPSIM-LIC to
register and retrieve a code to confirm to the HP SIM application that it is registered and to
discontinue the registration prompt. The First Time Wizard configures only the basic settings of an
initial setup for HP SIM. Refer to the http://www.hp.com/go/insightmanagement/sim/docs for
more information.
NOTE: If installing ServiceGuard Manager for the first time, install ServiceGuard Manager 5.0.
To download ServiceGuard Manager 5.0, see http://www.hp.com/go/softwaredepot, for more
information.
When you install HP ServiceGuard Manager, it recognizes and registers HP SIM.
