To Determine the Unix Kernel Parameters

OS	LOCATION	COMMAND TO SEARCH
AIX	automatically configured	do 'env' for LINK_CNTRL, To determine if AIX is 64 bit enabled do 'genkex | grep 64' or 'genkex | grep call' (see Note 1019106.102)
HP	/stand/system or use SAM -->Kernel Configuration	/etc/sysdef, /usr/sbin/kmtune (kmtune desupported in 11.31, use /usr/sbin/kctune -v), or /usr/sbin/kcweb -F
Tru64	/etc/sysconfigtab	/sbin/sysconfig -q ipc or /sbin/sysconfig -q vm or /sbin/sysconfig -q proc
Solaris	/etc/system	"/etc/sysdef | grep SHM" or "/etc/sysdef | grep SEM"
Linux	/usr/src/linux/include/asm/shmparam.h /usr/src/linux/include/linux/sem.h /proc/sys/kernel/sem /proc/sys/kernel/shmall /proc/sys/kernel/shmmax /proc/sys/kernel/shmmni	ipcs -lms
Mac OS X	/etc/sysctl.conf	"# /usr/sbin/sysctl -a | grep "

O/S Software Installed Packages and Patches

OS	COMMAND FOR PACKAGES	COMMAND FOR PATCHES
AIX	lslpp -w | grep -i "software title" (applies to APARs and PTFs)	/usr/sbin/instfix -ik patch number
HP	Prior to 11: /usr/sbin/swlist -lproduct PH\* hp-ux 11 and after: * /usr/sbin/swlist -l patch \*\.*,c=patch * /usr/contrib/bin/show_patches (from patch PHCO_19550)	/usr/sbin/swlist -l fileset | grep -i
Solaris	/bin/pkginfo -l | grep -i "software title"	/bin/showrev -p
Tru64	/usr/sbin/setld -i | grep -i "software title"	/usr/sbin/setld -i | more For patchkits: /usr/sbin/dupatch -track -type kit
Linux	To see if a particular RPM is installed (without the architectur): $ rpm -qa | grep "package name" To see if a particular RPM is installed (with the architectur): $ rpm -qa --qf "%{NAME}-%{VERSION}-%{RELEASE}_%{ARCH}\\n" | grep "package name" To see what RPM provided a particular object/library: $ rpm -q --whatprovides --qf "%{NAME}-%{VERSION}-%{RELEASE}_%{ARCH}\\n" "full path/library name" To see the contents listing of an RPM: $ rpm -ql "RPM name" For example: $ rpm -ql compat-libstdc++-33-3.2.3-47.3.ppc /usr/lib/libstdc++.so.5 /usr/lib/libstdc++.so.5.0.7
Mac OS X	to be supplied later	to be supplied later

To Check if an OS is 64 bit Capable or not

OS	COMMAND	RESULTS
Aix	lslpp -L | grep 64bit	It should return "bos.64bit"
HP	getconf KERNEL_BITS	It should return "64"
Solaris	/bin/isainfo -kv	If the isainfo command does not exist it is not 64-bit. It should return "64-bit sparcv9 kernel modules"

To Check version of Compiler

COMPILER	COMMAND
C/C++	do a "which cc", then cd to the directory it is in, then do a "what cc" except for Linux, on Linux do a "rpm -qa | grep egcs
COBOL	cd $COBDIR and do "more cobver"
Fortran	do a "which f77", then cd to directory it is in, then do a "what f77"
