Full Discussion: Memory limit for C program
Operating Systems AIX Memory limit for C program Post 302546059 by DGPickett on Wednesday 10th of August 2011 09:59:20 AM

It may ignore you if your platform or the specified target platform is not 64 bit address capable. However, it says it would warn.

The pdf says '=' after -bmaxdata, not ':'.

Does -qmaxmem= apply?

Are 64 bit libs in use/in dynamic search path?

Cute: setting compiler optimization space too big may exhaust swap!

Did you know that if you create a nominally huge ufs file with seek and write, only 1 block is used? Then, mmap6() allows you to do sparse array in 64 bit space, where missing entries are nulls for free (use RAM but no disk).

(Some sleazy money grubbers leave out options unless you buy a more premium compiler, so try gcc/g++ 64 bit and see if it works when this does not!)

Good luck!

installboot

installboot(1M) 														   installboot(1M)

NAME

       installboot - install bootblocks in a disk partition

SYNOPSIS

       installboot bootblk raw-disk-device

       The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition.

       The  ufs  boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be
       found using the -i option of uname(1).

       The installboot utility is a SPARC only program. It is not supported on the  architecture.  users should use installgrub(1M) instead.

       bootblk	       The name of the bootblock code.

       raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is  read-
		       able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive.

       Example 1: Installing UFS Boot Block

       To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use:

	      example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk 
		   /dev/rdsk/c1t0d0s0

       /usr/platform/platform-name/lib/fs/ufs

	   directory where ufs boot objects reside.

       /platform/platform-name/ufsboot

	   second level program to boot from a disk or CD

WARNINGS

       The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device.
