Tuning HP SIM (Optional)

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%. See the dbc_max_pct man page for additional details.For HP-UX 11i v2 (September 2004 or later) (B. 11 .23), these parameters are dynamic, and when you modify the parameters, a reboot of the system is not necessary.

	NOTE: The kernel tunable parameter dbc_max_pct is obsolete for HP-UX 11i v3.
