Shell scripts maintenance tasks for DBA

Most of companies use shell scripts to monitor DB activities, i just want to make myself familier with the main scripts, and how to manage them. If someone can send me some help material.

Sorry, I should have been more explicit and not only point to the initial page but directly, where the script library is. And I should have made clear it is not a final product, but the base to build your own library.
First link (orasnap) refers to the work made by Stewart McGlaughlin, who created a comprehensive collection of frequently used dba scripts. He compiled those scripts into an utility named orasnap. This you can download it from his yahoo site, if you take enough time to follow the links. Out from this collection of scripts I have personally taken several to tailor them into specific Unix/Dos shell maintenance scripts. I mean the homework is not finished, Out from his work I have taken a good base to build my own most frequently used Shell Maintenance Library.
The second link belongs to Tim Hall (http://www.oracle.com/technology/community/oracle_ace/ace1.html#hall) whose remarkable work has greatly contributed to the Oracle technical community daily job. Once again, this site doesn't have finished shell scripts for you simply to cut and paste, but the dba scripts I pointed plus a little effort and several interesting concepts and tips you can find navigating through his site turn this site into a first hand reference.

Trying to run Power shell Script on task schedule

My case is i'm trying to run a power shell script through the task schedule.

Enable Re-Indexing Maintenance Task for SCCM 2012 R2 Database?

If I use the
MaintenanceSolution.sql script provided by Ola Hallengren here:
http://ola.hallengren.com/sql-server-index-and-statistics-maintenance.html
and then use this SQL script weekly to rebuild the SCCM 2012 R2 indexes:
EXECUTE dbo.IndexOptimize
@Databases = 'USER_DATABASES',
@FragmentationLow = NULL,
@FragmentationMedium = 'INDEX_REORGANIZE,INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE',
@FragmentationHigh = 'INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE',
@FragmentationLevel1 = 5,
@FragmentationLevel2 = 30,
@UpdateStatistics = 'ALL',
@OnlyModifiedStatistics = 'Y'
Then do I still need to enable the built-in database re-indexing maintenance task in the SCCM 2012 R2 console?
Thanks

In the Channel9 video, the statement is made that the built in Rebuild Indexes "maintenance task does not always work and that it is kind of broken, but it works sometimes and not always." Can anyone provide further
details regarding the state of the Rebuild Indexes
maintenance task? Why does it only sometimes work? Should it be used at all? Has it been fixed with a CU since the video came out? Are there plans to fix it?
I need to defrag my database, and I am trying to determine the best approach.
Thanks!

Wait for a "do shell script" command to finish

i have an applescript that has to call a few external applications. i currently do this by setting the exact syntax of the external command in a string variable, then issue a "do shell script cmd" (seen many examples across the net using this standard)
my applescript continues beyond these commands. how do i set the applescript to either wait for the above external command to finish, or not?
regards
jingo_man

Usually AppleScript will wait for a shell script to complete before it continues, but adding an ampersand (&) at the end of the shell script command will make it run in the background, which allows the AppleScript to continue. See Technical Note 2065: do shell script in AppleScript for more information.

How to Prompt for User/Pass Running Shell Script Remotely through ARD

So I finally got my Active Directory Script working! However, I realized that I'm not the only one going to be running this script and to have my user name and password in the script itself is beyond foolish. While I know it's possible just to have whoever's running the script to manually add their username and password, I'd prefer to have prompts to make things easier for the rest of my team.
Here's my current script. I've tested it on the machine I'm connecting to Active Directory and it works fine if you run it on the machine itself in terminal. However, I'm going to be doing this on about 150 machines and the whole point of the script is to do it remotely.
#! /bin/bash
MACNAME=$(scutil --get ComputerName)
read -p "User Name: " USER
read -p "Password for $USER: " PASS
dsconfigad -add "CORP.DOMAIN.NET" \
-username $USER \
-password $PASS \
-computer $MACNAME \
-mobile disable \
-mobileconfirm disable \
-localhome enable \
-useuncpath enable \
-shell /bin/bash \
-ou OU=Macs,CN=Computers,DC=corp,DC=DOMAIN,DC=net \
-force \
-localpassword "PASSWORD" \
-groups "GROUPS"
When I run the UNIX script through ARD to a machine, I get no prompts for USER or PASS. In fact, it gives me the following error "dsconfigad: Authentication server encountered an error while attempting the requested operation. (5202)" So it's not asking for a user name and password.
Is there any way to make a shell script prompt you for a User Name and Password when you're sending commands remotely through ARD? Or is there another way to do this?
Any suggestions would be greatly appreciated.
-rks

Best solution is to create an account that is exclusive to binding machines. By doing this, you can embed the user name and password in the script. Heck, you can post it on your website. If the account is configured properly, it will only be able to create machine records in a defined container. If you are mixing Macs and PCs in your AD domain, I also recommend creating an isolated container for your Mac records. Now, the account has even less access rights as you can make it so it only has rights to the Mac container.
Otherwise, ARD does not prompt. You can play around with an expect script but the reality is that you are still embedding the credentials in the script so it really does not achieve what you want. ARD is not an interactive shell scripting tool. It is more a fire and forget.

Shell scripting

Hi,
I dont know about shell scripting .since iam involved in the database administration side i dont know have much knowledge in unix shell scripting.
so, wat part does this shell scripting taked in database administration.so wat are all the things which i should get familiar to gain good knowledge in shell scripting.
so kindly provide me some docs/metalink IDS which will enrich my knowledge in shell scripting.
As a DBA upto wat level i should be good in shell scripting

Hi;
I dont know about shell scripting .since iam involved in the database administration side i dont know have much knowledge in unix shell scripting.
As a DBA upto wat level i should be good in shell scriptingI belive atleast you have to learn until u can write some control or backup script or when you see some scripts you can understand what they are doing. There is no level or limitation to say "My information enough".
For instance i can type some scripts here but when i go some client they have wirtten and run scripts which can has more than 300-500 line scripts. Its mean its depend your workaround and company or clients needs&requests.
so, wat part does this shell scripting taked in database administration.so wat are all the things which i should get familiar to gain good knowledge in shell scripting.You can type many scripts as:
For backup
For check tablespace status
For check alert log error
For compiling invalid objects
and so on.
so kindly provide me some docs/metalink IDS which will enrich my knowledge in shell scripting.I suggest check first Hussein Sawwan previous greatest post about similar topic:

Reg: UNIX shell script at File Adapter

Hi all,
I am doing a File to file scenario and using command line arguments in Sending file adapter. I am using UNIX shell script ".sh" file for executing the command.
I gave the following path at "Run OS command before message processing" parameter:
/temp/xidelivery/send/FILOSC004_shell.sh
and this file contains following code:
#!/user/bin/sh cp /temp/xidelivery/send/FILOSC004_in.txt /temp/xidelivery/send/FILOSC004_input_copy4.txt
I put the source file, FILOSC004_in.txt and shell script files at the respective paths.
If I give "cp" command directly in command line it is working fine. But I could not execute this with shell script. Can any body give me the reason where I gone wrong.
Regards,
Pavani.

Hi,
can you try this,
bash /temp/xidelivery/send/FILOSC004_shell.sh
let me know.
hey you can check the blog below to catch the OS errors,

Import through Shell Scripts

Hi Friends ,
I have run shell scripts for importing from my local system through TELNET It was running fine on the server.But now I need to import the same dump file into my local database.The ORACLE_SID refering to the database in the server is same as the database in my local system.
So how to tell through the scripts that I need to connect to my local system.
If anyone could explain this it could be of great help.
Regards
Marlon.

Hi
It depends on how your script is taken care on syntax of import/export. I can tell you exaxtly if you can past me your import/export shell script. However for your knowlege, you can specify ORACLE_SID with export/import with following ways
1) exp user/pass@ORACLE_SID file=<file_name> log=<logfile>
imp user/password@ORACLE_SID file=<dumpfile> fromuser=<username> touser=username
if you are at same box where oracle server is intalled then you need not to mention oracle_SID but make sure that ORACLES_SID is configured in environment variable.
All the best
Alok

Running Shell Script

Hi all,
I need to run shell script on one of linux servers while executing some IdM workflow.
There is no need to manage that server/ provision accounts / reset passwords etc but just to run the script and to process the result.
I have IdM 8.04 installed on Windows Machine.
What are my options to achieve that mission?
Thank You,
Alex.

I was considering a situation similar to AD after actions where sometimes we execute a dos batch file for any specific purpose like creating home folder using mkdir. I was thinking on similar lines if your shell script is also for a specifc function similar to the one I mentioned above and if it is applicable in windows environment, you might covert that into a dos batch and do similar to an after action.
Since you need your shell script to be run in UNIX / LINUX machine, I do not see any other way other than writing a java class and invoke within a wf as it was mentioned by etech or if you are planning on using any of the out of the box resource adapters, the AIX resource adapter reference might help, but I have not worked with that

Need advice on shell scripting

If my message is better suited for a more specific group, please suggest it.
I have a job opportunity: managing a lab of mixed Windows and Macintosh desktops. Two job requirements are:
* Experience administering and deploying server hardware and software
* Proficiency with scripting languages, e.g. perl, python, shell
My question: what sort of shell scripting is typical for this sort of work?
I'll be grateful for any help.
Cheers,
noob81

At the entry level, administering operating systems via scripting involves managing filesystems, applications and users.
I would suggest to pick a book on "Administration" and on "Scripting" and this should provide an idea on what is being administered and what could be scripted.
For Windows, look for guides on "command-line administration" and "vbscript/powershell scripting".
For Mac, the below link should get you started.

Can we call shell script from oracle 9i?

Hi experts,
I wanted to know can we call shell script from oracle 9i procedures? If yes,how
Thanks
Shaan

No. I can't think of a way to do this...
If you want you can use DBMS_SCHEDULER to call OS SHELL scripts within.
For e.g.
CREATE PROGRAM
begin
dbms_scheduler.create_program
program_name => 'CHECK_TIME',
program_type => 'EXECUTABLE',
program_action => '/opt/oracle/chk_date.sh',
enabled => TRUE,
comments => 'Check the Time'
end;
CREATE A SHELL SCRIPT
opt/oracle> cat chk_date.sh
#!/usr/bin/ksh
echo "The date is :`date`"
CREATE SCHEDULE
begin
dbms_scheduler.create_schedule
schedule_name => 'EVERY_30_MINS',
repeat_interval => 'FREQ=MINUTELY; INTERVAL=30',
comments => 'Every 30-mins'
end;
CREATE JOB
begin
dbms_scheduler.create_job
job_name => 'RUN_CHECK_TIME',
program_name => 'CHECK_TIME',
schedule_name => 'EVERY_30_MINS',
comments => 'Run the program CHECK_TIME every 30 minutes',
enabled => TRUE
end;
MANUALLY RUN A JOB
exec dbms_scheduler.run_job('RUN_CHECK_TIME');

Help with broken shell script

Hi,
We had the shell script below created for our school last year to keep the students from jumping off of our wireless network so they had to go through our content filters. We put the script on all of the student laptops (MacBooks and MacBook pros) so it ran as a process in the background. It worked beautifully for the whole year.
Now we are in the process of upgrading our laptops from Snow Leopard to Lion and we've discovered that the script no longer works in Lion. I am guessing it is something simple but I don't see it. Does anyone know what about the OS changed that would cause this script to stop working?
Thanks
Tim

Brilliant, that worked perfectly! Thanks for the your help Linc.
Coincidentally, I found a posting on the website stackexchange.com that helped explain why it stopped working in the first placed and why "Airport" alone used to work in Snow Leopard.
Note what it says at the bottom:
"the port name is Wi-Fi on 10.7 and AirPort on 10.6. The device name can be at least en0,en1, or en2 depending on your setup."

About shell scripts for large-scale automation of encoding tasks

in the user menu of Compressor, it said that we can use the command line to write shell scripts for large-scale automation of encoding tasks.
I would like to have more information about the shell script for compressor, is that any document link?
Thanks

You can use a script function to set-up a more secure environment that you call at the start of every admin script. This could be your main stamp album for stuff that can be moved there.
A few more stamps to add to the collection (be sure to read up on them before use):
1) reset the command hash
hash -r
2) prevent core dumps
ulimit -H -c0
3) set the IFS
4) clear all aliases (see unalias -a)
Also you can remove the ALL from sudo and add explicit commands to the the sudoers file. There's a lot of fine tuning you can do in sudoers - inc. env variables as teekay said.
But I'm no expert so best to check all of the above.
