I have multiple PowerShell script files that I need to execute in a sequential flow(one after other). Can someone please help me how to schedule multiple PowerShell files to be executed using a SSIS Package. And I need to build a fault tolerant model were I need to re-execute a powershell script in case of failure.
Running PowerShell
There isn't a built-in Execute PowerShell task (pity) so you'll need to use an Execute Process Task with the path to powershell.exe
Something that you will need to take into consideration is that the default execution policy for PowerShell is Restricted which cannot run a script. Further complicating matters is the account that runs the SSIS package will also need to have its execution policy modified to be able to fire off those scripts. It's a simple matter of Set-ExecutionPolicy RemoteSigned or whatever level you feel is appropriate but you'll need to do this from within the account.
Fault Tolerance
The simple approach is to ignore the return code in the Execute Process Task. Alternatively, if the desire is to keep running the PS1 until it doesn't fail, then you'd wrap a For Loop Container around the Execute Process Task and only set the terminal condition once the task returns a success value. Things might still go sideways depending on what the failure is.

Is it possible to execute the Unidata process from the Unix Command line??
If it's possible, can anyone please let me know how to??
I just want to add some Unidata Processes into the shell script and run it from the Unix
Cron job.

Unix Command line
Yes! There are several approaches, depending on how your application is setup.
Just pipe the input to the udt process and let 'er rip
$cd /path/to/account
$echo "COUNT VOC" | udt
This will run synchronously, and you may have to also respond to any prompts your application puts up, unless it is checking to see if the session is connected to a tty. Check the LOGIN paragraph in VOC to see what runs at startup.
Same, but run async as a phantom
$cd /path/to/account
$udt PHANTOM COUNT VOC
This will return immediately, the commands will run in the background. Have to check the COMO/PH file for the output from the command. It's common for applications to skip or have a cut down startup process when run as a phantom (check for #USERTYPE)
If none of the above work because of the way your application is written, use something like expect to force the issue.
spawn udt
expect "ogin:"
send "rubbleb\r"
etc.

I'm new to Jitterbit and I'm working in Jitterbit Studio 5.6.0.1. In our deployed project we have 4 consequential operations and the first one is scheduled. What I want to do is to put a condition on the first scheduled operation that it should not run until all operations from the previous run are finished. I want to avoid running the operation twice. Any help?
Thanks
First off, I would suggest upgrading your studio to 8.12 (current version). Aside from that, if you add a script before the operation that you want to check, you can use something along these lines:
isInQueue=GetOperationQueue("<TAG>Operations/Your_Operation</TAG>");
isRunning=isInQueue[0][1];
if(isRunning==1 && isRunning!=Null(),
"Do Something";
);
That's just a very basic idea of how you can handle this. In my situation, I have an operation that has just a script like this in it, that either direct to a script to run if not already running, or direct to a dead-end, if it needs to skip this scheduled instance.
I wanted to know how can I set an variable from shell job available in pentaho kettle, which can be accessible by further Jobs(Simple evaluation) in the workflow.
I am trying to create a workflow where I have a start element which would trigger as shelljob to check the folder presence, if the folder is present then set one variable. The next job is Simple evaluation which needs to check if the variable(Set by shell job) is true that proceed with the workflow or terminate the workflow.
Start-->ShellJob(check folder created and set variable)-->SimpleEvaluation Job.

Good question. I'm not aware of such capability, as the "Execute a shell script..." step isn't designed to be a data pipeline. Furthermore, what values should/can a script return to you? Is it the result of an echo? A shell script could essentially be anything. I would say there's a reason why there is no built-in functionality for that in PDI.
Having said that, what you could do is something like this:
Execute a script, at the end of it write the variables into a text file on the file system
Create a sub-transformation that reads the variables from the file you've written in the shell script step, and then stores it/them in global scope variable
Evaluate the variables in the job
It may seem a bit cumbersome, but it should do the job for you, since you're asking to use the Shell Script step in a way it's not really designed to be used.
Here's an example of a high-level implementation (implementation of the sub-transformation should be very simple):
I hope it helps.
In SSIS package i have multiple scripts running within a job. At any given time i want to read how many scripts have been executed eg, 5/10 (50%) have been completed. Please tell how can i achieve that?
Currently there is no such functionality provided by SSIS to track progress of package execution.
It seems you need to write your own custom utility/application to implement same or use third party one.
There are few ways to do -
Using a switch called /Reporting or /Rep of DTEXEC at the command-line . For example:
DTEXEC /F ssisexample.dtsx /Rep P > progress.txt
2.Implement package logging or customize it.
3 . Implement Event handler on required executable. You can also use OnPipelineRowsSent log of Data Flow Task.
If you want to write your own application then below thread will provide nice starting point.
How do you code the Package Execution Progress window in C#
In my experience, we are using another software to monitor the jobs that are running. http://en.wikipedia.org/wiki/CA_Workload_Automation_AE
You can also try to create your own application that runs on the background that checks that status of your jobs, through checking the logs.
i have an access database backend that contains three tables. i have distributed the front end to several users. this is a very simple database with minimal functionality. i need to import certain rows from a file every hour into one of the tables in the database. i would like to know what is the best way to automate this process so that i can have it running hourly. i need it to be running sort of as a service in the background. can you tell me how you would do this?
You could have for example:
a ms-access file with all necessary code to run the import proc
a BAT file containing the command line(s) that will run this ms-access file with all requested parameters. Check ms-access command line parameters to see the available options.
a task scheduler service software to launch the BAT file: depending on the task scheduler and the command line to be sent, you could even avoid the BAT file step
If all you want to do is run some queries, I would not do this by automating all of Access, but instead by writing a VBScript that uses DAO to execute the SQL directly. That's a much more efficient way to do it, and will run without a console logon (which may or may not be required for full Access to be run by the task scheduler).
