What is "nmz" on cron job?

after we installed VIS demo database (R12), I found rapidinstall put one entry on cron job. Look like this job relate to concurrent manager.
0,15,30,45 * * * * JAVA_HOME=/u4/oracle/VIS/db/tech_st/10.2.0/jdk /u4/oracle/VIS/db/tech_st/10.2.0/ccr/bin/emCCR -silent start
anyone can tell me what is this process really doing?
Can I stop it?
if I remove entry from cron job, what going happen?
Thanks.

According to Oracle MetaLink Doc ID 781925.1, the cron job belongs to the Oracle Configuration Manager (OCM) Collector. OCM is said to be packaged with all Oracle software distributions, including Critical Patch Updates, patch sets and product releases.
OCM documentation is available from Oracle at:

Cron jobs on Sun Solaris 5.10

Hi,
Following are the details of my Sun box:
SunOS ocmdf2 5.10 Generic_118833-33 sun4u sparc SUNW,Sun-Fire-V490
I am trying to set up cron job entries using the crontab file. I have copied over my crontab file from the HP-UX machine over to this Sun machine.
I have registered the file with the cron system by running the "crontab crontab.txt" command where contab.txt contains all my cron job entries. After doing so, I noticed that non of the cron jobs are getting executed. One of the cron job is given below for reference:
0 6 * * 2,3,4,5,6 . /usr/local/bin/all_roots > /dev/null 2>&1 ; ksh $TF_FEED_SRC/generate_feed_contents.com standard_feed > $TF_FEED_LOG/standard_feed.cron.log 2>&1
The above cron job entry runs fine on the HP-UX machine, but not on the Sun machine.
Following is the modified version of the above job for the Sun machine.
0 6 * * 2,3,4,5,6 (/usr/bin/ksh ". .profile ; cd /tapes/gen_scripts ; generate_feed_contents.com standard_feed > /tapes/logs/standard_feed.cron.log 2>&1")
Note that in the above modified job, the env variables like TF_FEED_SRC and TF_FEED_LOG are replaced with the actual paths and quotes and parenthesis are used.
Can somebody please advise on:
1) Why the original cron job does not run?
2) What should I do to make the original cron job run?
3) What makes the modified cron job runs?
Thanks in advance for your help.
Regards,
Shiv

From the above shown email, it is clear that the shell used by cron is sh and not ksh. May be this is the reason why the /usr/local/bin/all_roots script is not able to run properly and due to this the
environment variables are not getting set.That's exactly correct. From the crontab man page:
     The shell is invoked from your $HOME directory with an arg0
     of sh. Users who desire to have their .profile executed must
     explicitly do so in the crontab file. cron supplies a
     default environment for every shell, defining HOME, LOGNAME,
     SHELL(=/bin/sh), TZ, and PATH. The default PATH for user
     cron jobs is /usr/bin; while root cron jobs default to
     /usr/sbin:/usr/bin. The default PATH can   be   set   in
     /etc/default/cron; see cron(1M).
Can anyone help to understand what is going on here and how to fix it?Set the variables before running the program
Method 1) set in the crontab
* * * * * VAR=value /path/to/script --option=$VAR
Method 2) use a wrapper script
* * * * * /path/to/wrapper
While cron will use /bin/sh to run the line, there's nothing that keeps the wrapper script from being anything in particular (such as a ksh script).

Cron job not running - script uses rsync, ssh (with id_rsa)

Does anyone know how to get cron to run a rsync/ssh script which uses id_rsa for passwordless logins?
I have a backup script I have slaved for months over that works wonderfully when running it from the command line.
It uses rsync and connects with SSH (passwordless using ssh keys). I have setup id_rsa and id_rsa.pub for passwordless logins (this is my user account, and connects using root@ to the server)
As stated all works find when run from the command line. But when I setup a cron job to run this file (exact same line I run from the command line) it does not execute. Actually, it does run, as I have an email notifiction which sends to me. It is just the rsync/ssh part that does not run.
I have spent days and days trying to figure it out. No error messages occur, nothing. Took me a while to find out cron is emailing the user account on Lion the messages (not to a proper email address).
The error shows a permission denied, which I believe to be the cron user cannot use the id_rsa/ssh connection.
Cron is running the script as my user, the same I use on the command line. I even tried copying the id_rsa to the root user .ssh folder in case cron is running as root but that does not work either.
So does anyone know how to get cron to run this rsync/ssh script which used id_rsa for passwordless logins?
Thanks a lot

YES! Got it working, finally!
So the issue is indeed cron/launchd not being able to access the ssh-agent which holds the key.
So this is the solution...
Download keychain for Mac:
http://www.funtoo.org/wiki/Keychain
Then once its installed and configured, the script to run needs this added to the top:
eval `keychain --noask --eval id_rsa` || exit 1
Note I am using id_rsa whereas keychains instructions refer to id_dsa so I just changed it and it works OK.
When the script runs the first time it asks for the key password. Then it works from then on.
What I do not know yet is will I need to re-enter the password when I logoff/logon again. That will cause an issue as I auto restart the Mac every day which means if I am off for a few days backup will stop (can you see the madness in this issue!).

How to take the cron job log in HP UX?

Hi,
How to take the cron job log in HP UX
I need to run a backup and other stuff everyday. How do I check and start cron service under HP-UX UNIX operating system? How do I write cron jobs?
A. Cron service is required to run jobs and tasks such as backup.
You must login as the root to run following commands. Each user that is using the cron service must have a cron configuration file in the /var/spool/cron/crontab directory. Also users are permitted if their name appeared in /var/adm/cron/cron.allow file
Task: Find out if cron is running under HP-UX
Type the following command at a shell prompt
# ps -ef | grep cron
Open /etc/rc.config.d/cron file
vi /etc/rc.config.d/cron
Set control variable to 1 to enable cron: CRON=1
Set control variable to 0 to disable: CRON=0
Close and save the file. To start or stop cron you can type the following command:
# /sbin/init.d/cron start <-- start cron
# /sbin/init.d/cron stop <-- stop cron
Task: HP-UX Start cron service
If cron is not running, simply type:
# cron
Task: Edit / create cron jobs
Type the following command to submit a cron job:
# crontab -e
List your cron file:
# crontab -l
Backup all your cron jobs:
# crontab -l > ~/backup.cron.jobs
Remove ALL cron job:
# crontab -r
Task: Crontab file format
Cron file format is as follows:
MIN HOUR DATE MONTH DAY /PATH/TO/COMMAND
0-59 0-23 1-31 1-12 0-6 /root/scripts/backup2tape.shEasy to remember crontab file format:
* * * * * command to be executed
| | | | |
| | | | ----- Day of week (0 - 7) (Sunday=0 or 7)
| | | ------- Month (1 - 12)
| | --------- Day of month (1 - 31)
| ----------- Hour (0 - 23)
------------- Minute (0 - 59)To run /root/script/backup at 23:00, every day, enter:
# crontab -e
Append following
0 23 * * * /root/script/backupRun foo job very weekday (MON-Fri) at 6am, enter:
0 6 * * 1-5 /root/script/backupFor more information refer to cron and crontab man pages.

You might note that all files normally found in /etc/init.d, /etc/rc*.d, and others are all in /sbin in HP-UX 10.20 and up.
Note too that your formatting is off in the description of the /etc/rc.config.d/cron file. Also, if you run /usr/bin/cron instead of /sbin/init.d/cron start, the /etc/rc.config.d/cron file is not used.

Need help with a cron job

What I want to do is run an Applescript every 6 hours and 1 minute. If the computer is asleep when the job comes due, I want it to execute the script and reset the counter. Can crontab do this? If so, how to set it up?

Gnarlodious wrote:
Then skip it, I can see there is no easy way.
I don't think it's that hard, though. Just a bit tricky. I was just a bit confused on what exactly you wanted.
I could write a stay-open Applescript application, but I wanted to avoid cluttering up the Dock just to run a command every 6 hours.
Nah, I wouldn't want that either.
If I were doing something like this and I wanted it to work like this:
1. Run every six hours, at 6 AM, noon, 6 PM, and midnight.
2. Run after waking up if the computer has been asleep and missed any of the times in between, say if you let the computer sleep thru the 6 AM job.
I'd do this:
1. Call the AppleScript periodically from a cron job. How often would be dependent on how tight you want the times to be to when you wake up.
2. Have the AppleScript save a text file somewhere with the time when it runs. That way, if your computer is asleep at 6 AM, the script could use this to decide if it missed running while it was asleep.
3. Have your script check this time and if it's over 6 hours, let the script do its thing. If not, then just exit, to try all this again the next time cron runs it.
Here's kind of a pseudo-code way of describing it:
check if it's 6:01, 12:01, 18:01, 00:01
if yes:
do your AppleScript business
save the current time in a file
exit
if it's not one of those times:
check if it's been over 6 hours since the AppleScript did its business
if yes:
do the AppleScript business
save the current time in a file
exit
if no:
exit
Then you could do two cron jobs:
1 */6 * * * /path/to/applescript
*/5 * * * * /path/to/applescript
The first one would run at your appointed times. The second would just run every 5 minutes to catch those times when the computer was asleep. The "5" could also be "10" for every ten minutes. Or whatever you decide you'd like.
I'd show you an AppleScript, but I'm really not so good at that. If a Perl script would help, I could whip one up pretty quickly, I think.

Cron job help- Need to run the Autobuddy command every night...

I have not written anything in the form of a Unix script for YEARS and YEARS. Our XServe was built in Advanced mode, currently running 10.5.4 Server. On this box, we are running Wiki and iChat. Since we built this box as an Advanced box the "Autobuddy" option was not available.
I have since enabled it at the command line, but I am told by Apple that there still needs to be a command run after every time a user logs in if you want others to Autobuddy. That command is this:
"sudo /usr/bin/jabber_autobuddy -m"
Now I think this would be pretty easy to setup as an automatic cron script, but like I said, I have not written something like this in forever. Not to mention, I am not 100% sure what needs to happen since running the script with an sudo command will prompt for the root password.
I was wondering if anyone would be able to help me write the script up, and give me some instructions on how to install it. I just want it run everyday, midnight is fine, I don't really care. All I know is that we have a dept of 150 people, and it grows and shrinks all the time. They can deal with a new user not being seen for 24-48 hours, I just want to get this automated.
Any helps would be GREATLY appreciated!
Thanks
Tom

If you want to keep it simple try [CronniX|http://www.abstracture.de/projects-en/cronnix] a graphical tool for setting up CRON jobs on OSX. Whilst I have not actually done an autobuuddy in this way, I cannot see any reason why it will not run as a Cron Job.
The proper way ideally would be to use the launchd service.
Something like this should work:

Schedule rman using cron job

I have scheduled a cron job to take rman backup of database everyday at 4PM. But I see that the empty backup.log file is getting generated while the script is not running. If I run the backup.sh script manually then the backup is running fine. The following are the scripts and the crontab details,
backup.sh script is as follows,
cd /u01/app/oracle/rmanbkp
rman target / <<EOF
run
allocate channel ch1 type disk format '/u01/app/oracle/rmanbkp/%d_%T_%s.bak';
backup database;
delete noprompt obsolete;
exit;
EOF
while the output of 'crontab -l' is
00 16 * * * /home/imsoracle/backup.sh > backup.log
Backup is not happening, what is wrong in my settings. Please advise.

Dear $ami Malik,
There is another option that you can use for RMAN scripting as shown below;
0 2 * * 2 export ORACLE_HOME=/oracle/product/10.2.0/db_1/ ;
/oracle/product/10.2.0/db_1/bin/rman cmdfile /db/optima/archive/OPTPROD/RMAN/backup_full.sh
log /db/optima/archive/OPTPROD/RMAN/backup_full.log
vals2:/home/oracle#cat /db/optima/archive/OPTPROD/RMAN/backup_full.sh
connect target sys/password@optprod
backup database format '/db/optima/archive/OPTPROD/backupset/DB_FULL_%d_%t_%s_%p';
backup archivelog all delete all input format '/db/optima/archive/OPTPROD/backupset/ARC_%d_%t_%s';
exit;So you can construct such backup strategy with the cmdfile and log options of the recovery manager.
Hope That Helps.

Need advice on running timer based cron jobs

Hi,
We made a cool desktop product on Flex that runs on the Air environment. After having released it a while ago, we think about taking its performance to the next level by being able to mimic cron job like functionality based on timers.
However, one of the setbacks for us while we tried to do something similar earlier was the Flash platform's single threaded architecture. So if we are running something resource consuming in the background, chances are that the UI might get stuck if a part of it is being rendered. That will make things looks ugly and we are trying to find ways to make it work.
Can anyone recommend anything that would help?
Thanks!

> 1. What is the best fastest system AE can take advantage of? If we get 6 or 8 or 12 core Mac Pros (instead of the quad core) with more RAM, would AE be able to access that speed, and if so up to how many GB can it use, only up to 2GB per core or can it use more?
Yes, After Effects will take advantage of multiple fast CPUs and all of the RAM that you can install.
You also want to have a decent-sized SSD connected over a fast bus for the disk cache. The new Mac Pro does very well in that regard.
2. Should we replace the graphics card with an Nvidia CUDA? Is the ray-tracing engine something we’ll need with Cinema 4D work?
The After Effects ray-traced 3D renderer has nothing whatsoever to do with Cinema 4D.
Do not make any buying decisions based on the After Effects ray-traced 3D renderer unless you already know for certain that you have a need for it. Since you're asking, it seems that the answer is that you don't.

RT i'd suggest you try out oracle enterprise manager and look at the list of events you can test for. You can use this list to implement in cron or let OEM do it for you. You'll find test like, is the listener up, is the db up, is the server up, what tablespaces will not be able to extend, if a disk is getting fulletc and stuff like that . Those items should help you frame your scripts for cron if you like.

Cron Job in Root Directory

I am running OS 10.4.6 on a Mac G4 450MHz machine. Recently when I opened Activity Monitor I noticed a cron job showed up in the root directory that hadn't been there before. I know I can select the cron job and then click on the Inspect icon but the dialogue boxes that show up do not tell me anything about the cron job except statistics having to do with CPU or memory usage. How do I find out what the cron job is and what it does? Is having a cron job in the root directory normal for 10.4.6? If it's not supposed to be there, how do I get rid of it?
Thanks for your help.
G4 Mac OS X (10.4.6) 450MHz with 768MB of RAM

David,
I think you are seeing the cron daemon. Not a "cron job". The cron daemon is started during the boot process. Cron then reads /etc/crontab. Crontab list "jobs" to be run and at what time. As of Tiger cron has been demoted and launchd handles running "jobs". Cron is still started at boot time but does nothing. It runs for backwards compatibility. There's nothing to get rid of- just leave it alone.

Hi
On OSX Client its in /usr/lib. You should see an alias for cron and within that should be what you want. However you might be able to achieve what you want with launchd and its utility launchctl? Consult the manual pages for usage.
There is a specific Terminal and Command Line Forum over on the 10.4 Server Forum:

Cron job to start machine.

Is there a way to get the machine to start, open iTunes and start playing a song at a specified time using a cron job?
MacBook Pro 15.4" - Intel Core Duo 2.0 Mac OS X (10.4.6) 2GB RAM

I have my computer do exactly what you want yours to do, except I don't use a cron job. In case you don't actually need to use cron, I'll tell how I get it to happen.
As mentioned by Federico_82, I use the Energy Saver preferences in System Preferences. There is an "Schedule..." button in the lower right corner that will allow you set the startup and/or shutdown times for the computer. It's not very detailed, but it suits my purposes for waking up Monday through Friday.
I also have the computer automatically log me in using the Login Options in Accounts preferences in System Preferences.
Finally, I've set alarms in iCal and chose "Open file" in the alarm section of the Info drawer. You can select a song file (or anything really) to be opened and the song will be played with iTunes since songs should automatically open with iTunes.
I've also set the final option in the alarm section to perform this 5 minutes before the time I set for the event, with the event time being the same time as the computer startup. This is okay because it will perform an alarm that was suppose to happen even if it couldn't do it earlier, for example because the computer was off. So you don't have to worry about timing it perfectly. Just set the alarm time to the same as the startup time for the computer or earlier if you want it to happen immediately upon startup, then the alarm will go off immediately after computer turns on and logs you in.
Also keep in mind you can set the event to repeat at various intervals in iCal, such as Monday through Friday or various discontinuous days of the week every week, and so on. Very customizable.
Personally, I use an Automator app to start playing a playlist in iTunes, and to set the iTunes volume to an appropriate level to wake up with just in case I've change the volume the last time I used iTunes. In this way, I can simply change the song in the playlist in iTunes without having change the alarm event in iCal. This helps because then I can copy/paste the alarm anywhere I want and don't have to worry about finding another song file if I want to change the song. Instead, I simply find the song I want in iTunes and put it in the playlist, along with any other songs I want have played.
If you do it with an Automator workflow, simply save the workflow as an iCal Alarm with "Save As Plug-in...". It'll automatically save in your ~/Library/Workflows/Applications/iCal folder, without you having to figure that out. Oh, and it doesn't hurt to test the workflow to make sure it plays your playlist (or whatever you have it do) before saving it as an iCal Alarm. Though, you can re-edit later if you want.
Once you've saved your workflow as an iCal Alarm, it'll show up in list of files to open in the alarm section for the event. So, after you've chosen "Open file" in that section, the default for the file will be "iCal", but you'll also be able to choose any iCal alarms you've saved in Automator or any other file (such as a document or a song).
Just as a bit of trivia, a plug-in you save in Automator is actually the same thing as saving your workflow as an application. The only difference is that the app is saved to a specific location so the Finder, or iCal, or Image Capture, etc., can find it. So, you don't have to know where to save it, Automator does that for you, but I told you where it is anyways (though you could use Spotlight) so you can get to it to edit it again if you want. Just drag and drop the app onto Automator or open it from within Automator to edit it again.
I hope that helps. Though it might sound kind of complicated at first, I think this way is much easier than dealing with a crontab and trying to synchronize it with startup and so on. You'll also find this way very customizable with the various options for iCal alarms and the many possibilities with Automator (if you choose to use a workflow instead of simply a song file).

From the cron man page: http://unixhelp.ed.ac.uk/CGI/man-cgi?crontab+5
"Step values can be used in conjunction with ranges. Following a range
with ``/<number>'' specifies skips of the number's value through the
range. For example, ``0-23/2'' can be used in the hours field to spec-
ify command execution every other hour (the alternative in the V7 stan-
dard is ``0,2,4,6,8,10,12,14,16,18,20,22''). Steps are also permitted
after an asterisk, so if you want to say ``every two hours'', just use
``*/2''."
Or, create a flag file with 'touch ran_cron_job_last_monday' after a Monday that you ran the script.
Then throw a condition into your script to check for the file. If the file exists, remove it. If the file doesn't exist, then run your script and when finished, create the file again.
For example:
#! /bin/ksh
if [ -e ran_cron_job_last_monday ] ; then
rm -f ran_cron_job_last_monday
else
touch ran_cron_job_last_monday
exit 0
fi
... do here what your script is supposed to do ....
exit 0

[Solved] Have Cron Job Open Terminal Window

I want to run a ping script every morning to check the liveliness and latency of specific servers. The script itself works fine but I can't figure out how to have cron open up a terminal window so I can see the script running.
This is what I have so far:
#runs /home/bran/pingservers.sh everyday at 8:30 am
10 10 * * * env DISPLAY=:0 konsole -e ~/pingservers.sh
But it doesn't open anything I don't even know if the job is even executing.
Last edited by brando56894 (2013-05-20 14:25:42)

I am unsure how to get the script to open a terminal, but the journal should have some information on whether the script is running or not and if there are any errors.
brando56894 wrote:
I don't even think cron jobs are running at all. I changed my job to
1 * * * * /bin/echo hello world
and it hasn't done anything...
As far as the job above, I just wanted to note that you have it set to run on the first minute of every hour. If you were looking for every second minute, you would want the following:
*/1 * * * * /foo/bar
