Does any one know what is the use of Zend's console?
any sample program ?
Console = the shell, or command line. If you have Windows go to Run and enter 'cmd', if you have a Mac open Terminal. Console scripts are useful for long processes or things you want to schedule to occur on a regular basis (the 'cron' RaYell refers to).
For example, I wrote a link checker script for checking links for websites we develop. It's used to help QA sites and check for errors. That command looks something like:
php linkchecker.php http://www.domain.com
The third bit is any arguments that are passed to the script. These can easily be accessed via Zend Console Getopt which is the only stable component of Zend_Console I'm aware of.
More info on Zend Console Getopt - http://framework.zend.com/manual/en/zend.console.getopt.html
There are details of Zend Console itself which are on the developer wiki, but I don't know if this is currently being developed - http://framework.zend.com/wiki/display/ZFPROP/Zend_Console+-+Wil+Sinclair
Zend console allows you to write console apps in PHP. It can be very useful if i.e. you want to run certain actions of your app with CRON.

I'm trying to figure out if I can launch a pre-built Alteryx workflow without launching the Designer - and without having Alteryx Server.
I came across a helpful post on Alteryx uses by #Runonthespot that, among other things, addressed running workflows from the command line, but doesn't go into detail. That discussion is here: https://stackoverflow.com/a/30469848/4313331. I don't have the rep to comment on his post and the question is closed.
He writes:
"Flows are runnable from the commandline on a server, and easiest way I've found (besides using Alteryx's own scheduler) is to save as an "App", and then run from the command line using the Alteryx engine executable, passing it parameters via xml file. You can save a sample xml parameter file from your flow by hitting the magic wand button (after saving the flow as a .yxwz (app)) This brings up a panel that lets you set the variables, and that panel has a handy "save" button which generates an xml file in the right format."
So, I'm looking for more info on this process. Is it simply a question of using Alteryx Server? Or is this a more interesting work around?
Thanks.
Yes, you can run a workflow (used generally to refer to a workflow, macro, or analytical app) without launching the Designer. You'll first need to understand how to run the workflow from the command line. The AlteryxEngineCmd.exe executable runs a workflow. It is located in the Alteryx install path in the bin subfolder. Here is where mine is located:
C:\Program Files\Alteryx\bin
It allows an additional parameter of an XML file with interface values. This is documented for analytical apps ONLY though it does work for macros as well. This is based on my extensive use of this undocumented feature.
Below are two examples:
AlteryxEngineCmd.exe MyWorkflow.yxmd
AlteryxEngineCmd.exe MyAnalyticApp.yxwz AppValues.xml
You can see a post here:
Alteryx Command Line Help
I prefer to wrap the command in a batch file and execute that for more control.
Now that you understand how to run the workflow from the command line, you can execute it anytime you want without launching Designer. Furthermore, you can use Windows Scheduler or a third-party tool to run the command or the batch file on a schedule.
Finally, you do need a license which enables API & Command Line w/ Scheduler. This is less expensive than Alteryx Server.
Have you tried C:\Program Files\Alteryx\bin\AlteryxEngineCmd.exe? It doesn't require server.
https://help.alteryx.com/2019.1/Command_Line.htm
If restrained by budget, you don't need a scheduler license (enables the AlteryxEnginecmd.exe), you can use a windows mouse clicker or even Powershell, to run the Designer though, without manual intervention.
I am proposing an idea for a final year project that is basically a virtual environment. I would be using Citrix XenServer in conjunction with Windows Server 2008 R2 and Citrix netscaler to make the server accessible over the web. I would also be hosting a website on the server that Windows is on.
What I was wondering is, would it be possible to trigger the execution of a script on the server from the web page. So basically a user comes along, goes to my website, registers their details. a csv file is then produced based on the details that are input. Then I was wondering is there a way to trigger the execution of a powershell script that would use the csv file to set up the user in Active directory. The powershell script itself is simple its just how I would get it to run is another thing.
Yes it is possible.
PowerShell lets us create graphical interfaces with the .NET winforms. With it, we can build front end to manage our scripts. It's a really nice feature, and tools like AdminScriptEditor make it pretty easy.
I have found this link for your reference - PowerShellOnWebPage
You can tweak/create the script as per your need.
Let me know if this helps.
Thanks!
I have a Websphere Application Server v8.0, and my job requires me to change the location of my JDBC data source to different values to test in different environments. I traditionally would do this via the admin console and change the settings via the Resources > JDBC > Data sources section, but I'd like to write a script to change these settings. When I run the admin console, where do the settings get stored? I can run the console vis-a-vis the Servers tab in Eclipse (Rational Application Developer) or by navigating to localhost:9044, but I don't know where the settings are stored - which I'd need to write said script.
Can anybody help me out?
From what I remember of WebSphere Application Server, the settings are ultimately persisted to the file system - however you shouldn't be changing them this way because application server config is a messy and complicated business and by directly changing settings you risk destroying your app server.
I'd recommend checking out this redbook, particularly Chapter 8 which describes how you can configure your app server with scripts. Also I seem to recall plans to display the equivalent scripting commands in the admin console.
If it helps, I had a quick look locally and found a reference to my JDBC data source in "resources.xml" located within the websphere directory at...
<server profile root>\config\cells\<aNodeCell>\nodes\<aNode>\servers\<aServer>
In the past I've used xml config to read values for convenience, but not often to update. Instead I have made use of some of the jython script options available and can echo Jim's response to check out the options there in case there is something that would be a viable alternative.
Edit:
There is another link that may be of interest Configuring data access with wsadmin scripting. I've not used this particular feature of wsadmin myself but it does appear to show promise at first glance.
If you want to write a script, then rather than looking at file system write a proper jython script, which will do your modifications in the similar way as you would do it via console.
To make writing script easier you can use:
Command assistance in the console - the Help portlet on the right shows last invoked command in jython
Script library, which already provides some scripts - Automating data access resource configuration using wsadmin scripting
And basic scripting commands - Configuring data access with wsadmin scripting
Eclipse uses console view as read-only.
How can I type command in console view? Is it possible? E.g: ls, mvn install...

Thanks Ben and Kelly.
I understand I can interact with Eclipse's console when my application is running. However, I meant I want an embedded console as like as the one in Kate, Dolphin (press F4 in Dolphin)... So I can use bash script in Eclipse's console. Is that possible? Or is there a plugin for that? I have googled but perhaps my keywords were not right...
Edited
Edward has found duplicate question here: Is there an Eclipse plugin to run system shell in the Console?
And it was answered :-)
I don't know how to mark this one as solved. So I place message here, I got the answer.
Edited
But it is not useful. It doesn't have auto complete feature, when I need to type a long file name, or want a hint for a forgotten name,... it is worst :-(
When the console is waiting for input it shows a green prompt that allows you type.
You can test it out by making a simple console application that reads from standard input.
You are trying to think of the Eclipse console as if it were connected to a command-line process. It is actually connected to the JVM used to execute your Java code. Thus, it only shows output that your program sends to System.out and conversely only is available for input if the Java code you are running is requesting input from System.in.
A decent exercise would be to write a small Java program that redirects the input and output to a child process of your favorite shell, for example: http://www.devdaily.com/java/edu/pj/pj010016
The Eclipse Console view is used for communicating with an executed program (typically Java, or similar). If you want to use it as a console, as mentioned in the comment under #Ben S's answer, the Target Management Eclipse project provides a view that can be used for that reason. I don't have it installed right now, so I cannot tell you the required plug-in/view name, but I have used it to connect to the local computer and works.
Is there a way to launch ColdFusion from the command-line?
I am not talking about launching the CF and related services with the net start command.
I remember doing this in the past. Basically, running CF from the command-line offered two advantages:
You didn't need to keep it as a Service and either have it always launch at boot-up or have to deal with the Services Manager
(more importantly) It echoed back to the screen all kinds of messages, especially error messages, which were helpful when actively developing (because you didn't need to go dig in the ColdFusion log files to find them)
It is possible that I'm mis-remembering and that this hasn't been available since ColdFusion 5.0. Is it at all possible with ColdFusion 9?
Update: Environment: Multi-server configuration with JRun.
Two ways to do this:
In development, add the server to ColdFusion Builder, and all the messages you talk about will show up in the console tab.
Start ColdFusion from the command line. The instructions are slightly different per environment but basically you want to get to bin directory and issue jrun start cfusion or coldfusion start or something similar . Post your environment for more specifics.
Go to C:\JRun\bin and issue jrun start cfusion
In your ColdFusion9/bin Folder you can find stop.bat and start.bat. Executing the latter gives you exactly what you want.
