CPU schedule policy

IBM Severity call definitions

AIX mirroring question
A reboot is necessary too (well technically speaking the mirroring will take place as soon as the mirrorvg, the reboot is necessary to take in account the desactivation of the quorum checking, therefore you need to schedule a reboot). regards, -

DLPAR operations

AIX make version
hello, like many other AIX commands, you define the version by the version of the fileset which brings the command. 'make' comes from the bos.adt.base archive (can be compared to a rpm archive), and you know the version of the archive / fileset with the 'lslpp' command, eg : lslpp -L... -

Customizing wsm?

Is it a PC or MAC ?

why 32bit kernel support more than 4GB mem
hello, there's a "trick" :)) first , consider a 32 bit adress : eg 0x2FFF FFFF. This kind of address is used by applications, and an application can not adress more thn 4GB of memory (2^32). The kernel has a broader range of adress space. Before to go on, keep in mind, that AIX kernel...
