need some information about psd_max_cores on 11.23

Praveen — Mon, 11 Aug 2008 09:10:58 GMT

Hi,

I need some help regarding psd_max_core which gives the maximum no of cores on the syste. We have two HPUX 11.23 systems, in /usr/include/sys/pstst/global_pstat_body.h file, one system doesnt have psd_max_cores and the other system has it. How do I find out when psd_max_cores was introduced on 11.23?? What patch level is needed to get the max number of core ( psd_max_cores API ) in the system?

B.11.23 U 9000/800 3706626100 ---> has psd_max_cores

B.11.23 U 9000/800 1816940680 ---> Does NOT have psd_max_cores

Please help

Shalom,

This appears to be related to a software library which is probably not installed on the second machine.

11.23 and 11.31 do not have kernel parameters by this name.

Shalom,

Is one of these machines a virtual machine?

This isn't a kernel parameter he's talking about, it is a field in the pstat_getdynamic() information structure [struct pst_dynamic].

PHKL_34912 introduced it, that is superseded by PHKL_36853. So either will provide it.

Note that these are intended to be used with MemFS and/or LEBM (hence they're defined out of the structure definition for other application builds).

Don has told you the solution. You can also figure this out for yourself by using:
swlist -l file | grep pstst/global_pstat_body.h

It should find an entry in the base OS. And another in whatever patch changed it.

pstat_getdynamic() information structure [struct pst_dynamic] was introduced in PHKL_34912 patch, that is superseded by PHKL_36853. So either will provide it.

I doubt enhancements of this nature would be made to 11.11.
