Are all Cron Jobs run by Root?

OS : Sun OS 5.10
I have scheduled an RMAN backup script which had only one line like
rman target .............I logged in as os user oracle and ran this script without any issue. But when i scheduled this job to run, it didn't work.
I got the error
/u05/bkp_scripts/rman-level0_WM.sh: rman: not foundThe shell couldn't find rman binary in PATH. Everything worked when i explicitly set ORACLE_HOME, ORACLE_SID, PATH in the shell script.
Does this mean a cron jobs scheduled by OS User oracle will still won't work unless you set set ORACLE_HOME, ORACLE_SID, PATH in the shell script?
Are cron jobs handled by root user regardless of who scheduled it?

cron does not execute the user's .profile. You must guarantee your environment by setting it inside the script.
Are cron jobs handled by root user regardless of who scheduled it?NO! root should NEVER be used for Oracle tasks. root should never be used for anything that can be done by another account.

  • Are all FX card running on 3 voltage levels - 0.8, 1.5, 3.3?

    I am wondering if all FX chipsets run on all 3 voltage levels. That is for example, I have a AGP 4x slot(1.5V only) and a FX 5700, will it run on my machine? Will the card automatically switch to 1.5V because i read it from somewhere that all FX chipsets run all on voltage signals. Also, my mobo only support 1.5V.
    Another question, does performance suffer alot when using a FX card on a AGP 4x slot compared to a AGP 8x slot?
    Thanks for all repiles.

    it will run at agpx4 and 1.5v
    yes its sloweer but only by a small percentage

  • 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!).

  • 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.

    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.

  • Manually running a cron job in SunOS 5.8

    I was looking in the Solaris documentation and UNIX Man pages, however how do I manually run a cron job that is already set-up? I am troubleshooting an issue and the cron job runs just fine during the night, I would like to execute it manually for testing purposes. Thank you in advance.

    Run this command :
    crontab -l
    And, look for the command you want to run and then just execute it on command line. The first five columns (separated by spaces) are date/time/day (skip those), after that you will see full path of the script/program. Just copy and paste that full path on command line.

  • User cron jobs won't run without home directory

    I have a situation where the users are defined through ldap without home directories, but our application creates cron jobs for these users. If a home directory is defined, the cron jobs run. If no home directory is defined, the cron jobs will not run. Is there a way to configure cron to use a global home directory, instead of the user's home directory?
    Kevin

    The crontab man page says that cron changes to the users home
    directory and then sets up some simple environment and run sh.
    it also talks about /etc/cron.d/cron.allow
    So it looks like those users need to be given a home directory
    like /tmp , but you need to think about the implication, are the accounts locked to stop logins
    truss -fpl $(pgrep cron)
    might show you what it is doing.
    it also talks about /etc/cron.d/cron.allow do you have such a file?

  • 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.

  • 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.

    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

    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).

  • Mount USB/Firewire drive from shell or cron job

    Is there a way to mount a USB/Firewire drive from the shell or possibly mount it using a cron job? Here's the situation. I have a user that keeps all of her data on her desktop or in her Documents folder. I have attached a firewire drive to her PowerMac G5 (OS 10.4.6) and successfully created cron jobs to backup her entire user folder every night. The problem is that she logs off of her computer before she leaves work. When she logs of the firewire drive unmounts and the cron job fails because it cannot find the drive. I was hoping there was a way to mount the drive using a script so that it will mount, let the cron job run, and then possibly unmount the drive afterwards. Any help with this would be much appreciated.
    MacMini, PowerMac G5, iMac   Mac OS X (10.4.7)  

    Try adding the following line to the beginning of the job:
    mount -a
    You may need to add u and/or w to the command after the a without any additional spaces for the mount to work properly.

  • Oracle Data Pump (expdp) credentials via cron job

    I have Oracle 10.2 on Linux Red Hat Server. In additions to performing appropriate backups of my database I also have a cron job I use to performa full logical export using expdp every night to export user objects in the event that a singleobjects needs recovered. This is an extra safeguard for object recovery.
    Currently I do my export (expdp) via a cron job run as the oracle software owner as a db user with db credentials specified. I would however like to change this script to essentially run as sys by doing something like "expdp / as sysdba... " However it appears doing so actually requires the password to be supplied and to run expdp as "expdp sys/password as sysdba".
    does anyone have experience performng an expdp as sys without specifying the password... essentially being able to do "/ as sysdba"?
    Hope that makes sense.
    Thanks for any suggestions.

    I appreciate all comments. At the expense of being long winded I did not get into all the details. But to be more clear I want to say
    1. I am using a parfile as to hide the password from the ps command.
    2. I also understand that doing it as sysdba is not recommended but i thought if I did so I could eliminate need for storing clear text password.
    3. This system is on a seperate "air-gapped" (a.k.a "sneaker-net") from the outside world and is a better protected than if sitting somewhere near the internet.
    4. Historically we have not been permitted to use OP$ accounts. This may be a legacy issue,and will (re-)investigate this as an option.
    5. Just to be clear, I really do not want to do a full export as sysdba. In fact currently I am doing it as a user with EXP_FULL_DATABASE role. However, that requires password to be stored in file (parfile). The file has it in clear text which is still not optimal because System Admins could gain access to this password (Yes I know system admins could do larger damage, but we still need to protect the passwords).
    I am going to look at calling the API directly, and OP$ if needed.
    Thanks for the suggestions.

  • SQL job running DTEXEC.EXE via PowerShell step produces wrong characters in result tables. Running the same DTEXEC.EXE in PowerShell x86 window produces correct results.

    I've created a package in SSDT (Visual Studio 2012) to import DBF tables into MSSQL 2014 via a wizard.
    Source DBF files contain tables with Russian (Cyrillic) characters in records fields.
    Created package works fine, produces correct results (imports Cyrillic characters as needed) while:
    •debugging in VS2012
    •deploying package in SSISDB and running the package via PowerShell x86:
    &"c:\Program Files (x86)\Microsoft SQL Server\120\DTS\Binn\DTExec.exe" /Server "server\mssql2014" /ISServer "\SSISDB\import\Integration Services Project16\Package1.dtsx";
    But when I create a SQL Agent job with a single PowerShell step that contains the same command and run the job it produces wrong characters in resulting tables. So, the problem is in wrong code page (or encoding). The correct tables with records are
    produced and job runs without errors.
    I tried
    chcp 1251; # 855, 866 -- all of them

    Running Leopard the scripts should auto run themselves unless the system is shut down. Back in Tiger you needed third-party utilities such as Anacron, a third-party app. such as Onyx or manually run the maintenance scripts.

  • 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

    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.

  • 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.

  • UNIX Command to run cron jobs

    Is there a UNIX command I can send to the target machines to force them to run the 'Daily, Weekly, & Monthly' cron jobs?
    Do you guys know of a place that I can find useful commands to send to the machines?

    Send:
    periodic weekly
    This command will run, right now, all the system maintenance commands which normally run via cron only at 4:30 on Saturday morning. To see the actual maintenance commands that are going to be executed, look in /etc/periodic/weekly. You can also do "periodic daily" or "periodic monthly".
