you lost the indentation, but let us ignore that

why are you using ksh?
Actually, let us ignore that as well

Your error

Code:

ps: Not a recognized flag: -

Usage: ps [-AMNZaedfklm] [-n namelist] [-F Format] [-o specifier[=header],...]

[-p proclist][-G|-g grouplist] [-t termlist] [-U|-u userlist] [-c classlist] [ -T pid] [ -L pidlist ]

Code:

function checkProcessIsOurService {

  local pid="$1"

  if [ "$(ps -p $pid --no-headers -o comm)" != "$javaCommand" ]; then return 1; fi

  grep -q --binary -F "$javaCommandLineKeyword" /proc/$pid/cmdline

  if [ $? -ne 0 ]; then return 1; fi

  return 0; }

see the bold..

AIX's ps is different to the one the script was written for

Code:

# Returns 0 if the process with PID $1 is our Java service process.

function checkProcessIsOurService {

  local pid="$1"

  if [ "$(ps -T $pid --no-headers -o comm)" != "$javaCommand" ]; then return 1; fi

  grep -q --binary -F "$javaCommandLineKeyword" /proc/$pid/cmdline

  if [ $? -ne 0 ]; then return 1; fi

  return 0; }

the rest of the ps, you will have to experiment..

post output of

Code:

ps | grep java

I honestly have no idea why that grep has --binary, we shall cross that bridge later..

Hi,

Done changes according to yr sugesstions. Here is the output.

Hi,

The problem seems to be with this command:

Code:

ps -p $pid --no-headers -o comm

AIX doesn't support the --no-headers option. Try changing your command to:

Code:

ps -p $pid -o comm | grep -v COMMAND

Hi there,

Surely you can figure some of this out yourself? The result is not the same. The "ps" error is gone, and you now have a "grep" error. The cause is the same - using arguments which are not supported by AIX. How about looking at the man page to try and fix it yourself?

Good luck!

I had not stopped the service yet but still status showing stopped. I replaced the -v option of grep with -R
old code

Code:

ps -p $pid -o comm | grep -v COMMAND

I replaced it with

Code:

ps -p $pid -o comm | grep -R COMMAND

I imagine they have sh available
you will not be changing their shell, only using it for the script..

However, that will not help you here, since the problem is the 'utilities' used in the script are using a different, incompatible syntax.

I did say you needed to experiment with that ps

found a manual ( which should have been very simple for yourself )
http://publib.boulder.ibm.com/infoce...ixcmds4/ps.htm

the -T was wrong,

Code:

-T pid        Displays the process hierarchy rooted at a given pid in a tree format using ASCII art.

              This flag can be used in combination with the -f, -F, -o, and -l flags.

so, you should be able to just drop the --no-headers, and use -o comm= ( not from above box, but the full manual, read it , I did and I'm not getting paid, you are. )

Code:

function checkProcessIsOurService {

  local pid="$1"

  if [ "$( ps -p $pid -o comm= )" != "$javaCommand" ]; then return 1; fi

  grep -q --binary -F "$javaCommandLineKeyword" /proc/$pid/cmdline

  if [ $? -ne 0 ]; then return 1; fi

  return 0; }

now your grep, I don't think you need --binary
from gnu's grep manpage on debian

Code:

      -U, --binary

              Treat the file(s) as binary.  By default, under MS-DOS and MS-Windows, grep guesses the file type by looking at the contents of the first 32KB read from the file.  If grep decides the file

              is a text file, it strips the CR characters from the original file contents (to make regular expressions with ^ and $ work correctly).  Specifying -U overrules this guesswork, causing  all

              files to be read and passed to the matching mechanism verbatim; if the file is a text file with CR/LF pairs at the end of each line, this will cause some regular expressions to fail.  This

              option has no effect on platforms other than MS-DOS and MS-Windows.

still, it shouldn't take much for you to work out the equivalent on AIX

Hi,

Friend,

Sorry if you had got hurted. It was my mistake. Actually i am not as expert in AIX as in Linux. As said before this script i had developed in linux and its working fine and i copy pasted the same script here. But due to your guidelines i had reached till here. And i am realy thankful for the same.
This is the 9th day (excluding weekoffs) where i am working on AIX. I even don't know the ABCD of AIX, but i am trying my best to make it possible.

You were right. they had sh shel available and i used the same now for script. I corrected the code as per yr suggestions. and here is the output.

Unable to understand this strange outputs. The service is running but the status is showing still stoped. I had not stoped the service yet.

Cannot open /proc/8257712/cmdline.

does not exist..

check the other files in /proc/8257712/ ,
Or check the cwd is a link to /usr/cachesys/od_bk/Server_Platform/ which is probably enough as a 'double check'

Yes there is a link pointing to the directory.

Code:



ls -lrtr /proc/8257712

I replaced the code

Code:

/proc/pid/cmdline

with

Code:

/proc/pid/cwd

the error gone but the status still showing stopped without any error.

Code:

 sh -x opensync_linux status

+ JAVA_HOME=/usr/java6

+ serviceNameLo=opensyncserver

+ serviceName=opensync

+ serviceUser=root

+ serviceGroup=system

+ applDir=/usr/cachesys/od_bk/Server_Platform

+ maxShutdownTime=15

?
you are trying to grep a symlink?

lets go back and see what you are doing

Code:

function checkProcessIsOurService {

  local pid="$1"

  # the PID is from a file ( created when service started )

  if [ "$(ps -p $pid -o comm=)" != "$javaCommand" ]; then return 1; fi

  # use ps to print the command of the PID we had in the file, 

  # if that command does not match what we expect it to be ( java ) return 1

  grep -q --binary -F "$javaCommandLineKeyword" /proc/$pid/cmdline

  if [ $? -ne 0 ]; then return 1; fi

  # the above serves as a double check, it could be a coincidence that the PID just happens to be java

  #  First problem, javaCommandLineKeyword is commented out in the OP

  # Next problem /proc/$pid/cmdline does not exist on AIX.

  # What was it intended to do?

  # check the file /proc/$pid/cmdline contains $javaCommandLineKeyword

  # (Opensync-angel-services-1.3.0.jar angel.plugin.Main)

  # since /proc/$pid/cmdline does not exist , look for the string in the other files in /proc/$pid/

  # if that fails, then test the cwd symlink

  # example..

  # JavaCWD=/usr/cachesys/od_bk/Server_Platform

  # ( stat -c %N /proc/$pid/cwd | grep -q "$JavaCWD" ) || return 1

  return 0; }

an alternative is to check the output of ps, it may truncate ( but I think that is only when output is to a term, grep should get the 'full' line... I think..not 100%

from manual

Code:

args

    Indicates the full command name being executed. All command-line arguments are included, though truncation may occur. The default header for this field is COMMAND.

Code:

( ps -p $pid -o args= | grep -q "$javaCommandLineKeyword" ) || return 1

Note, I have used list constructs
http://www.tldp.org/LDP/abs/html/lis...ml#LISTCONSREF
I honestly can't recall if they work in plain sh
re-write as if statements

Hi,

Friend,

Thanks for your most valuable help. It worked finally. I can't explain in words what u have done for me.

Here is the output.

Code:



opensync_linux start

-n Starting opensync

sleep: 0509-020 Specify time as a positive integer.

started PID=10027050



 ps |grep java

  7208978  pts/0  0:00 grep java

 10027050  pts/0  0:00 /usr/java6/bin/java -jar /usr/cachesys/od_bk/Server_Pla



opensync_linux status

-n Checking for opensync:

running PID=10027050



opensync_linux stop

-n stoping opensync



opensync_linux status

-n Checking for opensync:

stopped



 ps |grep java
