I am trying to run custom script on windows AWS AMI. The steps I am using is as given here:
http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/mon-scripts-powershell.html
My Instance is already associated with IAM role and credential file path is set.
I am trying to run following command in power-shell:
.\mon-put-metrics-mem.ps1 -mem_util -mem_used -mem_avail -page_avail -page_used -page_util -memory_units Megabytes
The error I am getting is:
Cannot bind argument to parameter 'Path' because it is an empty string.
Your script is not able to see AWS_CREDENTIAL_FILE env var.
So try loading ur credential file
setx AWS_CREDENTIAL_FILE C:\aws\myCredentialFile.txt'
Then open a new powershell window because if you attempt to run it in the same window, it will not see the AWS_CREDENTIAL_FILE env var. Now try running
.\mon-put-metrics-mem.ps1 -mem_util -mem_used -mem_avail -page_avail -page_used -page_util -memory_units Megabytes -verbose

I'm trying to execute bash script using karate. I'm able to execute the script from karate-config.js and also from .feature file. I'm also able to pass the arguments to the script.
The problem is, that if the script fails (exits with something else than 0) the test execution continues and finishes as succesfull.
I found out that when the script echo-es something then i can access it as a result of the script so I could possibly echo the exit value and do assertion on it (in some re-usable feature), but this seems like a workaround rather than a valid clean solution. Is there some clean way of accessing the exit code without echo-ing it? Am I missing on something?
script
#!/bin/bash
#possible solution
#echo 3
exit 3;
karate-config.js
var result = karate.exec('script.sh arg1')
feture file
def result = karate.exec('script.sh arg1')
Great timing. We very recently did some work for CLI testing which I am sure you can use effectively. Here is a thread on Twitter: https://twitter.com/maxandersen/status/1276431309276151814
And we have just released version 0.9.6.RC4 and new we have a new karate.fork() option that returns an instance of Command on which you can call exitCode
Here's an example:
* def proc = karate.fork('script.sh arg1')
* proc.waitSync()
* match proc.exitCode == 0
You can get more ideas here: https://github.com/intuit/karate/issues/1191#issuecomment-650087023
Note that the argument to karate.fork() can take multiple forms. If you are using karate.exec() (which will block until the process completes) the same arguments work.
string - full command line as seen above
string array - e.g. ['script.sh', 'arg1']
json where the keys can be
line - string (OR)
args - string array
env - optional environment properties (as JSON)
redirectErrorStream - boolean, true by default which means Sys.err appears in Sys.out
workingDir - working directory
useShell - default false, auto-prepend cmd /c or sh -c depending on OS
And since karate.fork() is async, you need to call waitSync() if needed as in the example above.
Do provide feedback and we can tweak further if needed.
EDIT: here's a very advanced example that shows how to listen to the process output / log, collect the log, and conditionally exit: fork-listener.feature
Another answer which can be a useful reference: Conditional match based on OS
And here's how to use cURL for advanced HTTP tests ! https://stackoverflow.com/a/73230200/143475
In case you need to do a lot of local file manipulation, you can use the karate.toJavaFile() utility so you can convert a relative path or a "prefixed" path to an absolute path.
* def file = karate.toJavaFile('classpath:some/file.txt')
* def path = file.getPath()
I have a console application that is written to take command line arguments which will be used in determining the number of Windows services are needed. The command line for the console application is like this:
consoleapp.exe -server:11 -azure:7
where -server specifies a Windows service and -azure specifies an Azure WebJob. [NOTE: This question only pertains to the Windows service but I wanted to show that the console application can potentially have many arguments.]
In the console application I parse the command line and, if the command matches "-server" then I want to create a Windows service using TopShelf. I can potentially have multiple -server commands on the console app command line, or single -server commands with multiple values, as in:
-server:11,7 or -server:11 -server:7
For each distinct -server/value I am creating a Task that in turn creates and starts a Topshelf service, like so:
TopshelfExitCode retCode = HostFactory.Run(x =>
{
x.Service<TopshelfWindowsService>(sc =>
{
sc.ConstructUsing(name => new TopshelfWindowsService(companyConfig, runnerProgress));
sc.WhenStarted((s, hostControl) => s.Start(hostControl));
sc.WhenShutdown(s => s.Shutdown());
sc.WhenStopped((s, hostControl) => s.Stop(hostControl));
});
//
x.SetServiceName($"CommRunner {companyConfig.CompanyName + companyConfig.CompanyId}");
x.SetDescription($"Runner for CompanyID ({companyConfig.CompanyId})");
x.SetDisplayName($"Runner {companyConfig.CompanyId}");
//
x.StartAutomaticallyDelayed();
});
My problem is that Topshelf apparently uses the console application's command line arguments during the service configuration and I end up getting an error:
"[Failure] Command Line An unknown command-line option was found: DEFINE: server = 11".
Is it possible to do what I am attempting and still use Topshelf? Is there any way to disable the use of the command line when configuring a service in Topshelf?
I could be wrong, but it sounds like your issue isn't really how to run multiple instances in separate threads, but more how to parse command line arguments of your own with TopShelf in use.
Have a look at the AddCommandLineSwitch functionality to allow you to create and use your own arguments.
x.AddCommandLineSwitch("server", v => server = v);
x.AddCommandLineSwitch("azure", v => azure= v);
x.ApplyCommandLine();
From this the syntax is:
-server:11 -azure:7
See How can I use CommandLine Arguments that is not recognized by TopShelf? for more information.
Remember, these only work during the install phase. To use these parameters for when the service starts, have a look at: How to specify command line options for service in TopShelf
I have nearly a hundred data sources in a WebSphere Application Server (WAS) and due to office relocation, the IP of the database servers have changed and I need to update the datasource IP addresses in my WAS too.
Considering it error-prone to update hundred IPs through admin console.
Is there any way that I can make the change by updating config files or running a script? My version of WAS is 7.0.
You should be able to use the WAS Admin Console's built-in "command assistance" to capture simple code snippets for listing datasources and changing them by just completing those operations in the UI once.
Take those snippets and create a new jython script to list and update all of them.
More info on command assistance:
http://www.ibm.com/developerworks/websphere/library/techarticles/0812_rhodes/0812_rhodes.html
wsadmin scripting library:
https://github.com/wsadminlib/wsadminlib
You can achieve this using wsadmin scripting. Covener has the right idea with using the admin console's command assistance to do the update once manually (to get the code) and then dump that into a script that you can automate.
The basic idea is that a datasource has a set of properties nested under it, one of which is the ip address. So you want to write a script that will query for the datasource, find its nested property set, and iterate over the property set looking for the 'ipAddress' property to update.
Here is a function that will update the value of the "ipAddress" property.
import sys
def updateDataSourceIP(dsName, newIP):
ds = AdminConfig.getid('/Server:myServer/JDBCProvider:myProvider/DataSource:' + dsName + '/')
propertySet = AdminConfig.showAttribute(ds, 'propertySet')
propertyList = AdminConfig.list('J2EEResourceProperty', propertySet).splitlines()
for prop in propertyList:
print AdminConfig.showAttribute(prop, 'name')
if (AdminConfig.showAttribute(prop, 'name') == 'ipAddress'):
AdminConfig.modify(prop, '[[value '" + newIP + "']]')
AdminConfig.save();
# Call the function using command line args
updateDataSourceIP(sys.argv[0], sys.argv[1])
To run this script you would invoke the following from the command line:
$WAS_HOME/bin/wsadmin.sh -lang jython -f /path/to/script.py myDataSource 127.0.0.1
**Disclaimer: untested script. I don't know the name of the "ipAddress" property off the top of my head, but if you run this once it will print out all the properties on your ds, so you can get it there

Modifying config objects using wsadmin
As an improvement to aguibert's script, to avoid having to provide all 100 datasource names and to update it to correct the containment path of the configuration id, consider this script which will update all datasources, regardless of the scope at which they're defined. As always, backup your configuration before beginning and once you're satisified the script is working as expected, replace the AdminConfig.reset() with save(). Note, these scripts will likely not work properly if you're using connection URLs in your configuration.
import sys
def updateDataSourceIP(newIP):
datasources = AdminConfig.getid('/DataSource:/').splitlines()
for datasource in datasources:
propertySet = AdminConfig.showAttribute(datasource, 'propertySet')
propertyList = AdminConfig.list('J2EEResourceProperty', propertySet).splitlines()
for prop in propertyList:
if (AdminConfig.showAttribute(prop, 'name') == 'serverName'):
oldip = AdminConfig.showAttribute(prop, 'value')
print "Updating serverName attribute of datasource '" + datasource + "' from " + oldip + " to " + sys.argv[0]
AdminConfig.modify(prop, '[[value ' + newIP + ']]')
AdminConfig.reset();
# Call the function using command line arg
updateDataSourceIP(sys.argv[0])
The script should be invoked similarly to the above, but without the datasource parameter, the only parameter is the new hostname or ip address:
$WAS_HOME/bin/wsadmin.sh -lang jython -f /path/to/script.py 127.0.0.1
I am new to hosting world (cloudcontrol), an i got some problem with application credentials, like database administration (mongohq), or google authentification.
So, will i put those variable with some kind of syntaxte (something like $variable) in the code, and then make a commandline with key-value as variable-value ?
If you are using Tornado, it makes it even simpler. Use tornado.options and pass environment variables while running the code.
Use following in your Tornado code:
define("mysql_host", default="127.0.0.1:3306", help="Main user DB")
define("google_oauth_key", help="Client key for Google Oauth")
Then you can access the these values in your rest of your code as:
options.mysql_host
options.google_oauth_key
When you are running your Tornado script, pass the environment variables:
python main.py --mysql_host=$MYSQL_HOST --google_oauth_key=$OAUTH_KEY
assuming both $MYSQL_HOST and $OAUTH_KEY are environment variables. Let me know if you need a full working example or any further help.
example:
First set a environment variable:
$export mongo_uri_env=mongodb://alien:12345#kahana.mongohq.com:10067/essog
and make changes in your Tornado code:
define("mongo_uri", default="127.0.0.1:28017", help="MongoDB URI")
...
...
uri = options.mongo_uri
and you would run your code as
python main.py --mongo_uri=$mongo_uri_env
If you don't want to pass it while running, then you have to read that environment variable directly in your script. For that
import os
...
...
uri = os.environ['mongo_uri_env']
I have a requirement to use powershell to configure IIS7.5 on WebApplications that have not yet had code deployed (possibly at all, possibly old/broken web.configs exist) to the file system. I would like to be able to do this all at the APPHOST level. (Note at the bottom about use of Powershell > AppCmd).
I can SET all the values properly, however, being somewhat diligent, I like to also validate the values were set properly by retrieving them after setting.
Here's the scenario:
I can set this value using AppCmd so the setting is applied at the APPHOST level using the /Commit:APPHOST flag. However, I havent found a way to READ the values exclusively at the APPHOST level.
Setting the Code is successful:
C:\Windows\System32\inetsrv\appcmd.exe set config "webSiteName/webAppName" -section:system.webServer/security/authentication/anonymousAuthentication /enabled:"True" /commit:apphost
However, I cant find a way to read the values using AppCmd (or Powershell):
Running the following AppCmd returns an error due to the broken pre-existing web.config in the folder (the specific error is unimportant, as it is reading the WebApp's web.config instead of the ApplicationHost.config/APPHOST):
C:\Windows\System32\inetsrv\appcmd.exe list config "MACHINE/WEBROOT/APPHOST/webSiteName/webAppName" -section:system.webServer/security/authentication/anonymousAuthentication
ERROR ( message:Configuration error
Filename: \\?\c:\inetpub\wwwroot\webSiteName\webAppName\web.config
Line Number: 254
Description: The configuration section 'system.runtime.caching' cannot be read because it is missing a section declaration
. )
Note: I would prefer to do this all in Powershell instead of using AppCmd, so if anyone has the syntax for modifying the APPHOST settings for anonymousAuthentication section of a WebApplication, that lives under a Website, from inside Powershell (Get-WebConfiguration seems to only use the WebApp web.config), that would be totally awesome and much appreciated!
Here's how to do this in PowerShell:
[Reflection.Assembly]::Load(
"Microsoft.Web.Administration, Version=7.0.0.0,
Culture=Neutral, PublicKeyToken=31bf3856ad364e35") > $null
$serverManager = New-Object Microsoft.Web.Administration.ServerManager
$config = $serverManager.GetApplicationHostConfiguration()
$anonymousAuthenticationSection = $config.GetSection("system.webServer/security/authentication/anonymousAuthentication", "simpleasp.net")
Write-Host "Current value: " $anonymousAuthenticationSection["enabled"]
# Now set new value
$anonymousAuthenticationSection["enabled"] = $true
$serverManager.CommitChanges()
