Helpful Linux Bash Scripts for I.T. Admins

I was wondering if you guys had any recommendations for helpful / simple Bash scripts that do helpful tasks in regards to Linux system administration? I have never created or used a Bash shell script but know that many of you guys do. I have no programming experience what so ever so decided to ask if you guys do have one or few scripts that are useful in basic administration tasks, could you please post them or at least point someone who is interested in the right direction?
Thank you so much!

I'm no sysadmin but one were to use command-line a lot i would give ZSH a shot. A nicely configured zsh shell can be unbelievably comfortable and is certainly a great tool.
As for scripts I always thought of them as little helpers customized for certain situations. For instance easing repetitive tasks, batching some steps and timing/automating little things. For general purpose I'd probably look at available software first.
Maybe tmux for terminal management, ranger for file management, a tiling window manager for efficiency, ssh and other survaillance/maintenance software? Personally, I'd very much like to hear, too, what software/scripts/.. linux systems admins use to keep the work to a minimum .

[solved]Need help with a bash script for MOC conky artwork.

I need some help with a bash script for displaying artwork from MOC.
Music folders have a file called 'front.jpg' in them, so I need to pull the current directory from MOCP and then display the 'front.jpg' file in conky.
mocp -Q %file
gives me the current file playing, but I need the directory (perhaps some way to use only everything after the last '/'?)
A point in the right direction would be appreciated.
thanks, d

You should also quote the variables and output in double quotes to make the code robust, e.g.
filename="$(mocp -Q %file)"
dirname="${filename%/*}"
cp "$dirname"/front.jpg ~/backup/art.jpg
Without the quotes, whitespace will break the code. Even if you don't expect whitespace in any of the paths, it's still good coding practice to include the quotes imo.
thanks for the tip.
here it is, anyhow:
#!/bin/bash
filename=$(mocp -Q %file)
dirname=${filename%/*}
cp ${dirname}/front.jpg ~/backup/art.jpg
then in conky:
$alignr${execi 30 ~/bin/artc}${image ~/backup/art.jpg -s 100x100 -p -3,60}
thanks for the help.

Pkgman - a bash script for local package and PKGBUILD management

hi all,
here is a script which manages a local repository and lets you edit
PKGBUILDs and other related files, automatically generates checksums,
build packages, add them to your local repo and so on.
it also has AUR support for submitting tarballs, leaving comments, etc.
get it from here:
http://sourceforge.net/projects/pkgman/
and AUR package:
http://aur.archlinux.org/packages.php?ID=17100
you need abs, curl and pacman and optionally namcap and desktop-file-utils.
RTFM online:
http://sourceforge.net/apps/mediawiki/p … n_man_page
first of all copy the pkgman.conf and AUR.conf files from /usr/share/pkgman to ~/.config/pkgman/ or ${XDG_CONFIG_HOME}/pkgman - if ${XDG_CONFIG_HOME} is set,
edit these two files and then run
pkgman --runmefirst
pkgman doesn´t install anything. if you want it just builds the package and moves it to your local repository. install it then with pacman.
it also has no dependency handling. there are many other tools which provide this.
the main intention was to keep track of package versions, different PKGBUILD versions and own AUR submitted tarballs; also to keep a clean local repository and clean build directories.
pkgman is stable now. i´m using it for months without any issues.
however, if there are problems or feedback please post them here.

changelog:
version 2.4:
*pkgman now respects the PKGDEST and SRCDEST variables from makepkg.conf. (though it still moves the src.tar.gz and .pkg.tar.gz to package backup directory).
version 2.5:
*pkgman uses PKGDEST if SRCDEST not set in makepkg.conf.
version 2.6 -> r26:
*changed version system: version 2.6 is now r26!
*minor changes: > pkgman uses now the $SHELL variable.
> new and more comprehensible manpage description (thanks to bender02)
version r27:
*changed SRCDEST since it's only a cache dir. all files (pkg.tar.gz and src.tar.gz) go to PKGDEST.
version r28:
*added new variable ShellCommand to pkgman.conf. Default is $SHELL.
*One might use an external application (like screen or xterm) to switch to build directory and edit files simultaneously.
version r30:
*minor changes. nothing crucial
r32: *OverwriteExistingPackage isn't used anymore. one can delete it from ~/.config/pkgman/pkgman.conf.
*minor changes
version r33:
*"-l|--list" also shows installed package version and available ABS/AUR PKGBUILD version for given package.
*"-a|--abs" can now also be used with other options (like "-e")
r39: * when backing up src.tarballs it asks whether to backup the source file or not
* more detailed "--list" option - also shows if package is installed or not and available ABS/AUR version
* added prompt to clean up directory after makepkg
* when checking pkg.tar.gz also possibility to check for conflicts with files of already installed packages
* use $PAGER instead of less
* --help directly shows the manpage
* --shorthelp shows a brief usage overview
* added a custom prompt, but only when using bash (is somehow experimental - works fine here for me)
* minor internal changes
* pkgman also reads ~/.aurvote file for getting aur name and password. if one already uses aurvote then there is no need for the
~/.config/pkgman/AUR.conf file.
r40: * new manual page & rewrite of usage function
* both option "--flush" and "--flushall" were omitted in favor of the more versatile "--cleanup" option
* pkgman <packagename> checks now if <packagename> is owned by user
* backup option after each editing
* added license
* minor internal changes
r41: * just small bug fixes, nothing crucial.
r42: * more bugs fixed.
r45: * new options added:
> --listversions: list local and available versions of installed packages from LocalPackages directory
> --getownpackages: synchronize local own packages with AUR
* added new variable in pkgman.conf:
> ListOutputInPager: output of, for example, "--list" or "--own" is piped into $PAGER
* added a new optional dependency "desktop-file-utils" for validating desktop entry files
* also supports now auto-generation of sha sums not only md5
* internal fixes due to AUR interface changes:
> use of json interface
> correct parsing of package category
* added 2 proto files (located under /usr/share/pacman):
> proto.desktop: a template for *.desktop files
> PKGBUILD-lib32.proto: a template for lib32 packages for x86_64
* some code changes and fixes
r46: * added new option to pkgman.conf (AutoGenerateSums).
> if AutoGenerateSums=no then pkgman asks whether to generate checksums or not.
> if set to yes it behaves like in former versions.
r52: * "--getownpackages" with more than 100 packages works again
* added new option "--cachecopy":
For each package in CacheCopyList (new variable in pkgman.conf) get existing package from pacman's cache directory - if
CopyPkgFromCache (new variable in pkgman.conf) is set to yes - and/or create a source tarball of PKGBUILD and related files from ABS -
if CopySrcFromABS (new variable in pkgman.conf) is set to yes - and copy them to package backup directory.
* added new variables to pkgman.conf:
> "CacheCopyList=file" - batch backup file, one package per line - default location is "$HOME/.config/pkgman/package.list".
> "CopySrcFromABS=[yes|no]"
> "CopyPkgFromCache=[yes|no]"
* some bugfixes
* docs completed
* CacheCopyList should look like
package1
package2
#this is a comment
! this too
package3
!package4
r54: * renamed "--listversions" option to "--diffversions". makes more sense!
from the man page:
pkgman --diffversions
Show differing ABS/AUR versions of installed packages from LocalPackages.
r55: * minor changes.
r57: * testing release
* added a new option "--rollback":
"pkgman <packagename> --rollback" - checks http://arm.kh.nu for available package versions,
lets you choose one, fetches the package and
moves it to the <packagename> backup directory (if "--repoadd" is used).
r59: * stable release
* new option "--rollback" (see r57):
it checks http://arm.kh.nu (Arch Rollback Machine) for available package versions,
downloads chosen file and moves it to local repository (if "-r|--repoadd" is used).
* posting files/comments/etc to AUR should work now again.
r65: *stable release
* new option "-M,--meta" to create metapackages and add them and their dependencies to local repository.
it searches for deps inside the backup directories, pacman's cache and if the packages are not available, it tries to fetch the missing
dependencies from the Arch Rollback Machine site (http://arm.kh.nu).
r66: * minor fixes
r68: * some bugfixes
* "--repoadd" and "--Reporemove" now accurately removes old packages from LocalRepository
r69: * small bugfixes when listing packages with similar names
* curl retries now 5 times if connection is not established
r75: * "--cachecopy" does not try to dl sourcefiles when backing up ABS PKGBUILDs
* some work on package splitting
* further internal changes
r76: * minor mistakes with "ln" purged
r79: * mostly small changes
* "--cleanup" now also removes uninstalled packages from LocalRepository
r81 & r80: * added AUR v1.6.0 support (use more json)
* small ARM changes ("--rollback")
r85:
* pkgman supports pkg.tar.xz packages
* some code rewrite, bugs purged (hopefully)
r113:
* pkgman now supports building split packages through makepkg.
If you already use pkgman you need to rerun "pkgman --runmefirst" after updating.
* new "-t,--template" option ("pkgman <packagename> --template <alt. packagename> [--pkgbuildversion <version>] [options]").
Useful to create a new PKGBUILD and use an existing one as a template.
* new option: "--conf /path/to/alternate/conf/file" - Specify another configuration file.
* pkgman now uses ${XDG_CONFIG_HOME}/pkgman or $HOME/.config/pkgman - if first not set - as the default location for its conf files.
r116:
* check inet conection when submitting src tarballs to AUR
* some bugs
* updated manpage on sf
For further details please read the manual page.

Bash script for checking link status

So I'm doing some SEO work I've been tasked with checking a couple hundred thousand back links for quality. I found myself spending a lot of time navigating to sites that no longer existed. I figured I would make a bash script that checks if the links are active first. The problem is my script is slower than evolution. I'm no bash guru or anything so I figured maybe I would see if there are some optimizations you folks can think of. Here is what I am working with:
#!/bin/bash
while read line
do
#pull page source and grep for domain
curl -s "$line" | grep "example.com"
if [[ $? -eq 0 ]]
then
echo \"$line\",\"link active\" >> csv.csv else
echo \"$line\",\"REMOVED\" >> csv.csv
fi
done < <(cat links.txt)
Can you guys think of another way of doing this that might be quicker? I realize the bottleneck is curl (as well as the speed of the remote server/dns servers) and that there isn't really a way around that. Is there another tool or technique I could use within my script to speed up this process?
I will still have to go through the active links one by one and analyze by hand but I don't think there is a good way of doing this programmatically that wouldn't consume more time than doing it by hand (if it's even possible).
Thanks

I know it's been awhile but I've found myself in need of this yet again. I've modified Xyne's script a little to work a little more consistently with my data. The problem I'm running into now is that urllib doesn't accept IRIs. No surprise there I suppose as it's urllib and not irilib. Does anyone know of any libraries that will convert an IRI to a URI? Here is the code I am working with:
#!/usr/bin/env python3
from threading import Thread
from queue import Queue
from urllib.request import Request, urlopen
from urllib.error import URLError
import csv
import sys
import argparse
parser = argparse.ArgumentParser(description='Check list of URLs for existence of link in html')
parser.add_argument('-d','--domain', help='The domain you would like to search for a link to', required=True)
parser.add_argument('-i','--input', help='Text file with list of URLs to check', required=True)
parser.add_argument('-o','--output', help='Named of csv to output results to', required=True)
parser.add_argument('-v','--verbose', help='Display URLs and statuses in the terminal', required=False, action='store_true')
ARGS = vars(parser.parse_args())
INFILE = ARGS['input']
OUTFILE = ARGS['output']
DOMAIN = ARGS['domain']
REMOVED = 'REMOVED'
EXISTS = 'EXISTS'
NUMBER_OF_WORKERS = 50
#Workers
def worker(input_queue, output_queue):
while True:
url = input_queue.get()
if url is None:
input_queue.task_done()
input_queue.put(None)
break
request = Request(url)
try:
response = urlopen(request)
html = str(response.read())
if DOMAIN in html:
status = EXISTS
else:
status = REMOVED
except URLError:
status = REMOVED
output_queue.put((url, status))
input_queue.task_done()
#Queues
input_queue = Queue()
output_queue = Queue()
#Create threads
for i in range(NUMBER_OF_WORKERS):
t = Thread(target=worker, args=(input_queue, output_queue))
t.daemon = True
t.start()
#Populate input queue
number_of_urls = 0
with open(INFILE, 'r') as f:
for line in f:
input_queue.put(line.strip())
number_of_urls += 1
input_queue.put(None)
#Write URL and Status to csv file
with open(OUTFILE, 'a') as f:
c = csv.writer(f, delimiter=',', quotechar='"')
for i in range(number_of_urls):
url, status = output_queue.get()
if ARGS['verbose']:
print('{}\n {}'.format(url, status))
c.writerow((url, status))
output_queue.task_done()
input_queue.get()
input_queue.task_done()
input_queue.join()
output_queue.join()
The problem seems to be when I use urlopen
response = urlopen(request)
with a URL like http://www.rafo.co.il/√ó‚Äò√ó¬®-√ó¬§√ó¬ê√ó≈ì√ó‚Ñ¢-p1
urlopen fails with an error like this:

Bash script for apache restart

I need a way of restarting apache for a user who does not have admin priveleges. My thought is that a bash script could be written to restart apache and would also have the admin password. The permissions would be such that the non-admin user could execute it but not read/write.
i.e.
sudo apachectl restart
??password??
I don't know if this is possible because sudo has -p but I didn't see --password
Mini Mac OS X (10.4.8)

Hi David,
   I've posted about sudo on two threads that are still on page one, Startup permissions change and system.log question. You shouldn't need a password and you can specify exactly who should be able to restart Apache.
   You probably think of sudo as an all-or-nothing solution; either a user can execute anything as root or nothing. Nothing could be closer to the truth. Not only can you specify individual commands but you can specify arguments as well. Thus, you could give someone the right to start or restart Apache but not to stop it. The perfect solution has been created for you; give it a whirl.

   ... an anecdote from IBM's Yorktown Heights Research Center. When a programmer used his new computer terminal, all was fine when he was sitting down, but he couldn't log in to the system when he was standing up. That behavior was 100 percent repeatable: he could always log in when sitting and never when standing.
   Most of us just sit back and marvel at such a story; how could that terminal know whether the poor guy was sitting or standing? Good debuggers, though, know that there has to be a reason. Electrical theories are the easiest to hypothesize: was there a loose wire under the carpet, or problems with static electricity? But electrical problems are rarely consistently reproducible. An alert IBMer finally noticed that the problem was in the terminal's keyboard: the tops of two keys were switched. When the programmer was seated he was a touch typist and the problem went unnoticed, but when he stood he was led astray by hunting and pecking.

Need help in creating script for "Task Schedule" in Oracle E-Bussiness Suit

Hi,
I need some urgent help regarding the scripting of Oracle E-Business Suite application. I am new towards working on Oracle Applications. I have been using LoadRunner 11.0 and protocol oracle applications 11i for the scripting of the application. The problem is as follows:
Scenario- Schedule an incident to a resource.
1) Log in to the application.
2) Open Oracle Forms Page.
3) Enter the details of the incident number.
4) Right click on the incident number and then select “schedule” option.
5) Check / Select the resource listed in the new form.
6) Click on “schedule” Button.
7) Exit the oracle forms.
8) Logout from the application.
I have recorded the scenario but when I try to run the script, it fails after completing the 4th step from the scenario mentioned above. I have done all the required co-relations..
Another issue that I have noticed in the scipt is that it records a lot of requests to the AppsTCFServer.
When I check the Tree View of the script, I have found that there are around 25 requests to the AppsTCFServer recorded in the script. In the header of these requests a TCF Start/Session number gets generated randomly. This number stays the same in few AppsTCFServer request headers and then a new number gets generated and the cycle continues.
However LoadRunner does not generate this number by itself during replay. I cannot find this number in any previous responses.
In the last few days, I have tried my hands on Oracle Openscript tool to record the above scenario, but still I am getting the same problem, i.e instead of getting the correct response from the server for the AppsTCFServer requests, I am getting the message "X-session 7098.... not found - aborting ".
I get this message whether I use LoadRunner tool or the OpenScript tool.
Please help me solve this issue.
Thanks & Regards,
Soumya Mukherjee

This isn't much of a "code-sharing" site but a "knowledge-sharing" site. Code posted me may be from a questioner who has a problem / issue / error with his code. But we don't generally see people writing entire scripts as responses to such questions as yours. There may be other sites where you can get coding done "for free".
What you could do is to write some of the code and test it and, if and when it fails / errors, post it for members to make suggestions.
But the expectation here is for you to write your own code.

Udev bash script for autodialing usb huawei modem

Hey
I've got an interesting one here.
I have scripted up a bash script to be triggered by a udev add event for my usb modem. As far as I can tell the udev event is firing correctly according to udevadm.
ACTION=="add", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1003", RUN+="/bin/sh /usr/local/bin/huawei_key.sh add"
ACTION=="remove", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1003", RUN+="/bin/sh /usr/local/bin/huawei_key.sh remove"
And heres the code from the script
#!/bin/bash
#returns
# 0 Successfully ran script for case
# 1 wvdial process already running
# 2 wvdial was not terminated
# 3 script was not ran with ADD or REMOVE events
function getpid #get process id of running program
pidof wvdial
if [ "$?" = 0 ];
then
pid=`pidof wvdial`
running=1
else
running=0
fi
function checkrun #check for a running copy of the program
pidof wvdial
if [ "$?" == "0" ];
then
running=1
else
running=0
fi
function killloop #a set of time kill commands to let the program exit gracefully
#two terms, one int and one kill with suitable gaps
getpid
checkrun
if [ "$running" = "0" ];
then
return
fi
kill $pid
sleep 10
checkrun
if [ "$running" = "0" ];
then

then
return
fi
kill -KILL $pid
sleep 5
checkrun
if [ "$running" = "1" ];
then
exit 2 #process fails to die
fi
function getlaststatus

then
last=`cat /var/run/huawie`
else
last=0
fi
if [ "$1" = "add" ];
then
getlaststatus
if [ "$last" = "1" ];
then
exit 1
fi
echo 1 > /var/run/huawie #block future udev events
getpid
if [ "$running" = "1" ];
then
exit 1
fi
modprobe usbserial
sleep 6 #modem init time
wvdial &

elif [ "$1" = "remove" ];
then

then
exit 0
fi
echo 2 > /var/run/huawie
killloop
exit 0
else
echo 3 > /var/run/huawie
exit 3
fi
I'd appreciate any ideas, this one has me stumped
Edit:
Forgot to add that when I call the script manually it works like a charm.

I'd appreciate any ideas, this one has me stumped
Edit:
Forgot to add that when I call the script manually it works like a charm.

NEED a java coder to help with a script for a programs of mine.

I play a game, very competitively, and need someone to make and compile a script for me. I am willing to pay upwards of 100 USD for this script made to MY standards. There will be a lot of work involved...Probably 12 hours studying my game and the purpose of the script(s). I will be buying 2-3 scripts, at roughly 50-100 USD each, depending on the quality. I will transfer the money via paypal, or other means if we can reach an agreement.
Please IM me at Chadtrapier on AIM or send an email to [email protected]
Or...Add me on MSN - [email protected]
We can reach an agreement with these scripts...
Thank you, I will also check this thread, so reply if you would like.
~Chad

Ummm. Do you think that's a lot of money or something? Think in the range of 40-60 per hour. And if you're talking about warcraft I don't think they java hooks to make bots. I think you need to figure out what your problem is first and maybe learn to code them yourself.

Help with a script for elder friend

First off, with apologies, I am not a script familar person at all. I have an elderly friend who is switching to Mac for the first time. I wanted a way to close all open programs, with a prompt to save any open files and then run a Time Machine backup and shut down - preferably without restarting next day with any windows opening automatically. Time Machine is set to run every hour but she's a writer and could lose work if Time Machine doesn't run before shutting down for the night. So I searched and found some small scripts that I tried to put together. I think it works but after Time Machine runs it waits a very long time before shutting down. I'm wondering if some of you kind folks could refine this for me. (I do realize that automator has a quit all programs that I can save as an app but I'm trying to make this a one step 'app' process.)
So what I have is this:
tell application "System Events" to set the visible of every process to true
set white_list to {"Finder"}
try
          tell application "Finder"
                    set process_list to the name of every process whose visible is true
          end tell
          repeat with i from 1 to (number of items in process_list)
                    set this_process to item i of the process_list
                    if this_process is not in white_list then
                              tell application this_process
                                        quit
                              end tell
                    end if
          end repeat
on error
          tell the current application to display dialog "An error has occurred!" & return & "This script will now quit" buttons {"Quit"} default button 1 with icon 0
end try
do shell script "/bin/bash -c '/System/Library/CoreServices/backupd.bundle/Contents/Resources/backupd-helper > /dev/null 2>&1 &'"
repeat
delay 5
          if not IsProcRunning("backupd") then
                    ignoring application responses
                              tell application "Finder" to shut down
                    end ignoring
                    exit repeat
          end if
end repeat
on IsProcRunning(theProc)
          try
                    do shell script "ps auxc | grep \"" & theProc & "\""
                    return true
          on error
                    return false
          end try
end IsProcRunning
.... frankly I don't understand most of this in reality but it's a need I'd like to help her with on her Mac Mini.
Many Thanks,
Brenda

First off, you're overthinking this. There's no reason why your friend would lose any data by not backing up prior to shutdown (unless she has a flaky hard drive that needs to be replaced). Assuming she's saving her work when she quits her apps, she should be fine.
Second, trying to auto-quit applications is dangerous. You don't check to see if any files need to be saved (there's no easy way to make that check anyway), and that in itself could cause data loss.
Third, time machine has its own command line utility: tmutil. There's no reason to script backupd.
Last, if I remember correctly, whether or not apps and windows reopen at startup can be set on a system-wide or per-application basis.
Give a clearer and more specific description of the goals you're trying to accomplish: what kind of apps are likely to be open, which of them will/might need to save data, what you want the machine to look like on restart, all with details. That would help a lot.

Need help with python script for Deluge

I am using Deluge 1.3.2 with web server, and all works fine, I use this script in the Deluge settings to execute upon torrent completion:
#!/bin/bash
torrentid=$1
torrentname=$2
torrentpath=$3
torrenttimedelta=`/usr/bin/python2 /home/bobby/scripts/deluge/torrentTimeDelta.py $1`
subject="Started download new torrent!"
message="$torrentname to $torrentpath"
echo -e `date`"::Finished downloading torrent:$2 in: $3" with id:$torrentid >> ~/logs/scripts.log
echo -e `sendEmail -t [email protected] -f [email protected] -u "deluge server notification: torrent $torrentname is complete!" -m "$torrentname has completed downloading at: $torrentpath and took $torrenttimedelta to complete :)" -xu [email protected] -xp password -v -o tls=yes -s email.com` >> ~/logs/scripts.log
echo ---------------------------------------- >> ~/logs/scripts.log
This is to email me when a torrent is done and works. What I wanted to add to this email was the time taken to complete the torrent. I have gotten help from Deluge forum in this thread: http://forum.deluge-torrent.org/viewtop … =9&t=36989 However I think it's something with Python within Arch that is the obstacle, and so that helpful person can't do much more IMO. The python script I'm using is:
#!/usr/bin/python2
from deluge.ui.client import client
from twisted.internet import reactor
d = client.connect()
def on_connect_success(result):
print "Connection was successful!"
def on_get_torrent_value(value):
for torrent in value:
print "%s: %s" % (torrent, value[torrent]["name"])
client.disconnect()
reactor.stop()
client.core.get_torrents_status({}, ["name"]).addCallback(on_get_torrent_value)
d.addCallback(on_connect_success)
def on_connect_fail(result):
print "Connection failed!"
print "result:", result
d.addErrback(on_connect_fail)
reactor.run()
Now if I call this from shell directly, it works. However, including it with my email script at the top, Deluge itself freezes and no email is sent. I run ps aux | grep deluge and I can see that the script has run, but apparently died and all is just hanging. I kill the script process and Deluge resumes just fine, the email is sent. Kinda confused how to remedy this, appreciate any help Thanks
P.S. When I get the email, the part that says ""$torrentname has completed downloading at: $torrentpath and took $torrenttimedelta to complete "" shows nothing where $torrenttimedelta should be, it just says "and took to complete"

[edit] Sorry, I don't use deluge and I messed up my test script. If the script is executable try `/home/bobby/scripts/deluge/torrentTimeDelta.py $1`
Are there any other errors? or try running bash with debug output to see if it will tell you something else
The problem you are having is bash doesn't recognize variables inside the tick marks.
Hope that helps

Linux Startup script for Forms Services 11g with Weblogic

Hi,
Does anybody know where I can find info about the startup script process for Forms Service 11g under linux? I can't find it googling it... I think I have to startup weblogic first... isnt it ? or opmnctl works alone ?
In 10g we just need to set env vars and then "opmnctl startall" and if we need enterprise manager "emctl start iasconsole" ... what about on 11g?
Regards
Ricardo

You can start directly the WLS_FORMS without starting the Admin and Node manager ..
I think if you go through this link , you will get more information ..

Need help with easy script for open / close app and move files

Hi,
I'm not a scripter.. never done anything special perhaps more complicated than /shutdown -s on cmd..
I actually learned ASCII C language on university but never used it in real.
I'm trying to create a basic script that perhaps you could help me or guide me how to do it..
The commands are
1) Close a running app (end task it or force kill it, I prefer end task it)
2) delete files from x location
3) run .exe app from y location
4) close that running app
5) move files from z to y
Perhaps adding few "wait few seconds" commands in between each, so the apps will launch successfully..
My first question will be whats the easiest script language to do that?
I tried VBScript but couldn't find commands for open or close apps.. also for controlling files..
And what commands can do that? I could google them up for better understanding no need for rough guide
And lastly, does it too hard? If it takes more than hour to make it (learn and process) than it ain't worth it..
Thanks alot ahead!
Jordan.

hmm 2 questions:
1) taskkill.exe causing me access deny error.. I used "taskkill.exe /IM softwarename.exe"
how do I get permission or something to fix that?
2) on the "move" command..
First, its a "copy" instead.. but I easily figured that out..
but more important is that I want to copy a folder.. with unknown list of way too long files and sub folders..
and all I see is ability to move a file..
Is this possible?
Thanks

Help creating a script for backup

Hi everybody,
I would like to make some backups using rman and recovery flash area on oracle10g on my Debian.
I would like to make a full backup level 0 on Sunday and make incremental backups from Monday to saturday.The best would be to have one for hot backup and one for cold backups.
But I am wondering how to schedule a task using rman. For example is it possible to write a script that would make the backups at a desired time executed by oracle?
Or do I have to create a script on unix that should be executed by cron?
You know I am really bad at scripting, but it would really help me if you could help me creating a script that would make the backup automatically on sunday at midnight and incremental eveydays until sunday.Here is the information I need to put in a script:
#flash recovery area creation under sqlplus
SQL> ALTER SYSTEM SET DB_RECOVERY_FILE_DEST_SIZE = 10g SCOPE=BOTH SID='*';
SQL> ALTER SYSTEM SET DB_RECOVERY_FILE_DEST = '/home/oracle/flash_recovery_area' SCOPE=BOTH SID='*';
#setting the default variable
ORACLE_SID=iscream;
#connect to target database:
rman TARGET SYS/oracle@iscream NOCATALOG
#set the defaults values for rman
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
CONFIGURE RETENTION POLICY TO REDUNDANCY 2;
CONFIGURE BACKUP OPTIMIZATION ON;
Any help will be appreciated
synthese
hot backup
using rman
using flash_recovery_area
full backup set compressed on sunday
incremental backup set compressed from mondy to saturday
using disk
policy retenttion 7 days
redondance 2

You can backup using some unix shell scripts.
rman is not really good one.
