C Calculating the Size of Kernels in Memory
(PA-RISC only)
One requirement of vPars is the sum of sizes of the kernels running in memory within a hard partition must
be less than 2 GB. This only limits the maximum number of virtual partitions that can be created. If you use
the defaults of the dynamic tunables, you will not run into this 2 GB limit. However, if you have adjusted the
dynamic tunables, you can perform the calculations described in this appendix to ensure you meet this
criteria.
For more information on dynamic tunables, see the white paper Dynamically Tunable Kernel Parameters in
HP-UX 11i at http://docs.hp.com.
