AIX5.1开始提供truss工具，但是常见的Aix4.3及以前的版本都没有该工具，在网上找了找，找到如下信息：

There's a third-party product for AIX 4 (and 3) which is similar to truss:sctrace, from SevOne Software.  It's quite good, but you do have to pay forit.AIX's trace facility is actually quite powerful (you can do some interestingthings if you dig into its innards and rewrite the template file), but it'snot nearly as convenient for quick tracing of a single process astruss/ltrace/sctrace.Michael Wojcik                402 438-7842Software Systems Developer    Micro Focus> -----Original Message-----> From: [e-mail] [mailto:[e-mail]]> Sent: Tuesday, December 18, 2001 4:13 PM> To: Minchu Mo> Cc: [e-mail]> Subject: Re: How to trace system level call in AIX > > > On Mon, 17 Dec 2001 20:36:12 GMT, Minchu Mo > <[e-mail]>  said:> > Somthing like truss in solaris, ltrace in linux.

truss Command
Audience: Administrators 
Date: June 22, 2001 
The "truss" utility traces system calls. It's a popular System V tool that allows administrators to identify performance bottlenecks within applications. 
The truss command is available in AIX starting in at version 5.1. The following shell script emulates the truss functionality in AIX 4.3. 
#!/bin/ksh# Name: truss.sh# Purpose: to make AIX trace look like the truss command# Caveat:  Unsupported tool. Use at your own risk.show_usage(){ echo "Usage: $0 [-P] [-n] [-p pid] [-t tempfile][-s sleeptime | command]"        echo "         -P           show process id's in the output"        echo "         -n           show process names in the output"        echo "         -p pid       trcrpt only for this pid" echo "         -s seconds   trace for  period of time" echo "         -t tempfile  path name to file that will be used for trace"        echo "         command      execute this command and stop trace/c" echo " after command is done./n" exit 0}[ "$#" = 0 ] && show_usageset -- `getopt t:s:p:nP "$@"` || show_usagewhile :; do        case $1 in                -s)     sleeptime=$2                        shift 2;;  -p) pid=$2   shift 2;;  -n)     EXEC="exec=on,"   shift;;  -P) PIDNUM="pid=on,"   shift;;                --)     shift                        break;;        esacdonecommand="$*"[ -n "$command" -a -n "$sleeptime" ] && show_usage[ -n "$pid" ] && PID="-p $pid" hooks="101,104,107,106,134,139,15B,130,19C,163,169,120,122,108,12E,14C,154,/152,15F,14E,137,135,13A,19B,13E,174,175,176,177,178,179,17A,17B,17D,17E,/17F,1A7,1A8,1A4,1A5,1A6,180,18F,195,18E,1A9,1AA,1AC,1AB,1F0,1AF,1AE,1AD"do_trace(){logsize=$1;bufsize=$2;trace -n -a -L $logsize -T $bufsize -j $hooks -do trace.out || return $?}do_trace 8000000 4000000 || { echo "You do not have privilege as this uid to allocate a large trace buffer" echo "Trying with a smaller buffer, but you may lose data" do_trace 8000000 1000000 || {  echo "You do not have privilege as this uid to allocate a large trace buffer"  trcstop  exit 1 }}trconif [ -n "$sleeptime" ]; then sleep $sleeptimeelse $command  # run the commandfi# do whatever you want heretrcstoptrcrpt -k 106 ${PID} -h -O ${EXEC}${PIDNUM}ids=0,timestamp=3 trace.out  # > trcrpt.out
