Hi everyone. I've been reading around and am a little bit overwhelmed, hoping to find a kind soul out there to hold my hand through writing my first script. This need has emerged at work and I haven't much experience writing shell scripts, but this is a problem we have with a production environment and I am tasked with providing the solution. After 3 days of staring and trying to Frankenstein together a solution, I'm no closer than I was when I started. I need some help, and so am kindly requesting it, with crossed fingers. I've put on my flame-retardant shield and am admitting I am a complete newbie off the bat. I'm at your mercy!
Here is the situation: we have a java process that keeps crashing. Normally in this situation we would monitor the existence of the pid file to tell us when it is available, but in this case the process is crashing due to a memory fault, which is leaving the pid file stranded. Therefore, it is necessary to periodically run a command, 'jps -l | grep cq' to see if the process is actually available, and interpret the result.
I have a few unique challenges in this case. First, I need to monitor on three different production boxes (all SunOS), but the directory where jps is kept is in two different locations. On one box it is:
Code:
/usr/jdk/jdk1.5.0_24/bin
and the other:
Code:
/usr/jdk/instances/jdk1.5.0/bin
Once I'm able to determine which location the command is to be run from, the command should be run, and if a line is returned then result is 0, if nothing is returned then 1.
It seems so simple but I'm lacking the know-how to put it all together.
I have bits and pieces but I'm sure there are large holes in the script:
Code:
if [-f $CMDPATH1\ $CMDPATH2
THEN
CMDPATH=$CMDPATH1
ELSE
CMDPATH=$CMDPATH2
fi
IF [ $PID == 0 ]
THEN
ERROR=1
ELSE
ERROR=0
FI
CMD="jps -l | grep cq"
So...help? If I left anything out please let me know - I'm very closely monitoring the thread. Thank you in advance.

I (only) know the pid of the process which was running earlier (say 5 hrs back) but it is not running now.
Is there a way I could find the details of that process? (atleast the name of the process). Please let me know. (2 Replies)

jazipconfig
JAZIPCONFIG(8) System Manager's Manual JAZIPCONFIG(8)NAME
jazipconfig - jazip(1) configuration tool.
SYNOPSIS
jazipconfig [--non-interactive]
DESCRIPTION
The jazipconfig script is a tool to easily build the /etc/jazip.conf file for the configuration of jazip(1)OPTIONS
The optional --non-interactive command line parameter instructs jazipconfig to do what it can to build a /etc/jazip.conf file without
prompting the user. On Debian systems, the command is invoked this way by the jazip package post-installation script.
In this non-interactive mode, the script looks through /proc/scsi/scsi for detected Zip or Jaz devices. If it find any, it looks up
/etc/fstab to see if it can find already specified mount points for them. If (and only if) it finds mount points, it writes the device and
mount point to /etc/jazip.conf
INTERACTIVE USE
If no command line options are provided, jazipconfig runs interactively. In this case, it also looks through /proc/scsi/scsi for detected
Zip or Jaz devices. If it find any, it looks up /etc/fstab to see if it can find already specified mount points for them. Then it creates
a user menu which you can use to create the /etc/jazip.conf file.
NOTES
The first entry listed in /etc/jazip.conf is the default device used when jazip is called without an argument.
