I'm using AIX 5.3.12.5 and trying to understand truss output.
I'm running a job with real time of 16 minutes but only 4 minutes of CPU time. I'm trying to understand what the process is doing.
I'm getting a lot of
kread,
kpread,
kwrite,
kpwrite...
What means each one of this calls?
Thanks a lot

To establish the connection it starts the child thread then it should transfer data. In reality it gets only connection.... (1 Reply)

acctcms
acctcms(1M) System Administration Commands acctcms(1M)NAME
acctcms - command summary from process accounting records
SYNOPSIS
/usr/lib/acct/acctcms [ -a [-o] [-p]] [-c] [-j] [-n] [-s] [-t] filename...
DESCRIPTION
acctcms reads one or more filenames, normally in the form described in acct.h(3HEAD). It adds all records for processes that executed iden-
tically named commands, sorts them, and writes them to the standard output, normally using an internal summary format.
OPTIONS -a Print output in ASCII rather than in the internal summary format. The output includes command name, number of times executed,
total kcore-minutes, total CPU minutes, total real minutes, mean size (in K), mean CPU minutes per invocation, "hog factor," char-
acters transferred, and blocks read and written, as in acctcom(1). Output is normally sorted by total kcore-minutes.
Use the following options only with the -a option:
-o Output a (non-prime) offshift-time-only command summary.
-p Output a prime-time-only command summary.
When -o and -p are used together, a combination prime-time and non-prime-time report is produced. All the output summaries are
total usage except number of times executed, CPU minutes, and real minutes, which are split into prime and non-prime.
-c Sort by total CPU time, rather than total kcore-minutes.
-j Combine all commands invoked only once under "***other".
-n Sort by number of command invocations.
-s Any file names encountered hereafter are already in internal summary format.
-t Process all records as total accounting records. The default internal summary format splits each field into prime and non-prime-
time parts. This option combines the prime and non-prime time parts into a single field that is the total of both, and provides
upward compatibility with old style acctcms internal summary format records.
EXAMPLES
Example 1: Using the acctcms command.
A typical sequence for performing daily command accounting and for maintaining a running total is:
example% acctcms filename ... > today
example% cp total previoustotal
example% acctcms -s today previoustotal > total
example% acctcms -a -s today

Unpredictable output results if -t is used on new style internal summary format files, or if it is not used with old style internal summary
format files.
