I have follow the instruction to install flow
https://www.youtube.com/watch?v=_HVx9Jqr34Q
it works perfectly. But if I restart my laptop, then i open "http://localhost:54321" it shows not connected.
Should I rerun the command "java -jar h2o.jar"? is that alway required if I want to open flow after computer reboot? is that an easy short cut to start flow?
Yes, you need to re-run java -jar h2o.jar after rebooting. Alternatively, you could have your OS start it, by running that command, during the boot process; the instructions for that vary by OS (and are outside the scope of StackOverflow, but are easy to google).

I've successfully run IOS UI Automation Instruments from command line on my local Mac. When it starts to test, the simulator will automatically pop up and then do the stuff.
However, when I SSH to a build server (with OSX and xcode, will use Jenkins eventually) and try to do the same thing, it doesn't work well.
Building process is fine, but as long as I run instruments, the terminal will then hang there without doing anything. I figure it has something to do with iphone simulator GUI but since it's CLI, I don't know what's going on...
Do you guys have any idea? Thanks!!
.
After executing the command from Jenkins through SSH; in most cases you would see a pop up window as in the screen shot. You will have to get past this screen to execute your tests. This post addresses how to get past that issue Stop "developer tools access needs to take control of another process for debugging to continue" alert
I've had the same issue. instruments -w "$DEVICE" were ignoring parameters.
Same with
DEVICE_TARGET='iPhone 6 (8.1 Simulator)' cucumber --format json -o test-reports/cucumber-8.1-iphone.json
It were ignoring DEVICE_TARGET parameter.
Solved via running Jenkins slave NOT as a SSH slave but as the Slave agent via java web start
http://i.stack.imgur.com/lNlPA.png
As i understand this issue is caused by OS X launchagent that managing sshd and performs scope of restrictions for remote users.
IMPORTANT! Slave agent should be started from OS X desktop, not via ssh! I've connected via VNC and launched slave java web agent on the OS X UI terminal.
I am currently trying to deploy smartfoxserver 2X on EC2 using dotcloud. I have been able to detect the private ip of the amazon web instance, and using the dotcloud tools I have been able to determine the correct port. However, I have difficulty installing the server proper via the command line so that I can log into it using the AdminTool.
My postinstall is fairly straightforward:
./SFS2X/sfs2x-service start-launchd
I find that on 'dotcloud push' there is a fair amount of promising output in my cygwin terminal, but the push hangs after saying that the sfs2x-service has been launched correctly, until timeout.
Consequently, my question is, has anyone found a way to install SFS2X on EC2 via dotcloud successfully? I managed to have partial success with SFS Pro, with a complete push to dotcloud, by calling ./jre/bin/java -jar installer.jar in my postinstall. Do I need to do extra legwork and build an installer jar for SFS2X? Is there a way that would be best to do this?
I do understand that there is a standard approach to deployment with SFS2X using RightScale on EC2, however I am interested in deployment using the dotcloud platform.
Thanks in advance.
The reason why it is hanging is because you are trying to start your process in the postinstall, and this is not the correct place to do that. The postinstall script is suppose to finish, if it doesn't the deployment will time out, and then get cancelled.
Once the postinstall script is finished, it will then finish the rest of your deployment.
See this page for more information about dotCloud postinstall script:
http://docs.dotcloud.com/0.9/guides/hooks/#post-install
Pay attention to this warning at the end.
Warning:
If your post-install script returns an error (non-zero exit code), or if it runs for more than 10 minutes, the platform will consider that your build has failed, and the new version of your code will not be deployed.
Instead of putting this in the postinstall script, you should add it as a background process, so that it starts up once the deployment process is complete.
See this page for more information on adding background processes to dotCloud services:
http://docs.dotcloud.com/0.9/guides/daemons/
TL;DR: You need to create a supervisord.conf file, and add it to the root of your project, and add your service to that.
Example (you will need to change to fit your situation):
[program:smartfoxserver]
command = /home/dotcloud/current/SFS2X/sfs2x-service start-launchd
Also, make sure you have the correct dotCloud service specified in your dotcloud.yml in order to have the correct binary and libraries installed for what your smartfoxserver application.
When I run my selenium test (mvn test) from jenkins (windows) I see only the console output. I don't see the real browsers getting opened . How can I configure jenkins so that I can see the browsers running the test?
I had the same problem, i got the solution after many attempts.
This solution works ONLY on windows XP
If you are using jenkins as a windows service you need to do the following :
1) In windows service select the service of jenkins
2) Open properties window of the service -> Logon-> enable the checkbox "Allow service to interact with desktop"
After then you should reboot the service jenkins
Hope this help you :)
UPDATE:
Actually, I'm working on a an automation tool using Selenium on Windows 10, I've installed Jenkins ver. 2.207 as windows application (EXE file), it's running as windows service and ALL drivers (Chrome, FireFox, IE) are visible during test executions WITHOUT performing a mere configuration on the System or Jenkins
I got the solution. I ran jenkins from command prompt as "java -jar jenkins.war" instead of the windows installer version. Now I can see my browser based tests being executed.
If you are already doing what #Sachin suggests in a comment (i.e. looking at the machine where Jenkins actually runs) and still do not see the browsers, then your problem may be the following:
If you run Jenkins as a service in the background it won't open apps in the foreground. You may either try to run it not as a service in the foreground, or run it as a Local System account and check Allow the service to interact with desktop option. In the latter case you may get into permission problems, though.
Update: To make sure this answer is understood properly by others: Jenkins Windows 'native' installation is not really native. It's a wrapper around Java that runs it as a service.
To interact with desktop GUI, you should launch slave agent via JNLP:
https://wiki.jenkins-ci.org/display/JENKINS/Distributed+builds#Distributedbuilds-LaunchslaveagentviaJavaWebStart
After adding the node in Jenkins (configured as Java Web Start launch), just make a startup batch script on the node machine:
java -jar slave.jar -jnlpUrl http://{Your Jenkins Server}:8080/computer/{Your Jenkins Node}/slave-agent.jnlp
(slave.jar can be downloaded from http://{Your Jenkins Server}:8080/jnlpJars/slave.jar)
See more answers here:
How to run GUI tests on a jenkins windows slave without remote desktop connection?
In the case of Windows 7 you should not install jenkins as windows application (because in this recent version, Microsoft decided to give services their own hidden desktop even you enable the functionality "interact with desktop" in jenkins service), you may have to deploy it from a war file as follows:
1) Download jenkins.war from Jenkins official site
2) Deploy it by the command prompt : java -jar {directoryOfJenkinsFile}/jenkins.war
3) Now you can access jenkins administration on http:// localhost:8080
Hope that helps you !
this is an issue for Jenkins. on Windows it is possible to access logon user's session (screen) under system account. to make the UI testing visible, Jenkins needs to bypass UAC (user access
control) at background. this solution works for me with my own service running as system account.
I also faced the same issue earlier in my local machine (Windows 10).
My test was running perfectly from the NetBeans but when I moved to Jenkins it was only running in console mode. I was unable to view the UI.
So for that, you just need to make your local machine as a Jenkins slave by creating a new slave node in your Jenkins and select that node to execute the Jenkins job.
If jenkins installed by windows installer it is showing only Console out put only. To see browsers download jenkins.war file and run java -jar jenkins.war from command line.
Go through this site:
http://learnseleniumtesting.com/jenkins-and-continuous-test-execution/
If you have the following situation,
You are able to login to the remote machine
You don't see the Jenkins agent window
This slave machine is accessed by many users then try the following,
then try the following suggestion.
Login to slave machine
Go to Task manager
Users
Logout all the users
Then login again.
This worked for me.
I am new to Hudson with PSEXEC, i am using hudson in my computer, i want to run batch file on remote computer from hudson build.
I used PSEXEC to run batch file on remote computer,when i executed from command promt it working successfully.But same i did from Hudson build its hanging..it's not doing anything.so please give any suggestions is there any other way we can handle this.
I want to do this quikly...urgent
Anyones help is appreciable
thanks in advance.
Could it be that psexec is waiting for a user entry? In this case hudson will hang.
Does Hudson runs with your user credentials? if not lunch a command Prompt with the credentials Hudson is running with and see what happens if you call psexec. If hudson runs on the local system account, you can't start a command prompt with it. Than try to run Hudson with your credentials and see what happens.
BTW, did you check Hudsons log files (just in case that there might be something)?
I had the same problem where PSEXEC simply hung.
The solution i found (after trawling for AGES) was to add the parameter -accepteula to the PSEXEC called. Hudson stopped hanging after that.
Very frustrating.
maybe it is too late, but I thought I will post it for others who have the same problem.
Psexec has problem running from any CI server, doesn't matter what CI server you have, is it Hudson, Teamcity, ...).
Psexec hangs when run from the build server.
It doesn't hang for all commands, but with some commands , psexec will hang.
The problem resides with how psexec will read the output of the remote running command.
The ultimate solution is to use other tools than psexec.
You can check this blog of this solution.
But if you need a simpler solution, and you don't care about the output of the command, I came up with a simple solution that suppress the output of the psexec.
You can write a small c# program that will run the psexec command, suppressing its output.
I blogged about that here
I thought I would respond to this since I was having the same hanging problem with TeamCity and psExec. Since I believe it is actually an issue with Java executing psexec, it should apply in the case of Hudson as well.
While I ran into the accepteula issue was early on, you only need to agree once and it sets a registry setting. As user327759 indicates the -accepteula switch in the script would cover your basis the first time and for ever after.
If this doesn't fix your problem, which it didn't in my case, you need to add the "-i" command switch. ex: psexec -i \ServerName "C:\folder\file.bat"
For context regarding this solution, I have included my backstory:
I was able to execute this PsExec command just fine via a MsBuild task, via a .Net wrapper and via straight command prompt usage, but TeamCity would just hang on the execution. It seems that Java is expecting some response on standard in, when it invokes the psexec exe. On the remote server I would see the psexecsvc process fire up and register in the services console appropriately, but then it would stop. After reading many posts such as this one, and struggling for far longer than I would care to admit, I eventually tried -i option, despite not needing this in any other execution scenario outside of TeamCity. The psexec documentation indicates that -i will "Run the program so that it interacts with the desktop of the specified session on the remote system. If no session is specified the process runs in the console session." It is still unclear to me why this makes all the difference for TeamCity.
In order to run one application, a batch file has to be kicked off (which does things like start Jetty, display live logs, etc). The application will work only if this batch file is running. I am hence forced to have this batch file running and not logout from the Windows server.
Can this batch file be run as a service? I am experimenting with one of the suggestions from a similar question.
NSSM is totally free and hyper-easy, running command prompt / terminal as administrator:
nssm install "YourCoolServiceNameLabel"
then a dialog will appear so you can choose where is the file you want to run.
to uninstall
nssm remove "YourCoolServiceNameLabel"
There's a built in windows cmd to do this: sc create. Not as fancy as nssm, but you don't have to download an additional piece of software.
sc create "ServiceName" start= demand displayname= "DisplayName" binpath= [path to .bat file]
Note
start=demand means you must start the service yourself. Options include: boot, system, auto, demand, disabled, delayed-auto
whitespace is required after =
I did encounter an error on service start that the service did not respond in a timely manner, but it was clear the service had run the .bat successfully. Haven't dug into this yet but this thread experienced the same thing and solved it using nssm to install the service.
No need for extra software. Use the task scheduler -> create task -> hidden. The checkbox for hidden is in the bottom left corner. Set the task to trigger on login (or whatever condition you like) and choose the task in the actions tab. Running it hidden ensures that the task runs silently in the background like a service.
Note that you must also set the program to run "whether the user is logged in or not" or the program will still run in the foreground.
On Windows 2019 Server, you can run a Minecraft java server with these commands:
sc create minecraft-server DisplayName= "minecraft-server" binpath= "cmd.exe /C C:\Users\Administrator\Desktop\rungui1151.lnk" type= own start= auto
The .lnk file is a standard windows shortcut to a batch file.
--- .bat file begins ---
java -Xmx40960M -Xms40960M -d64 -jar minecraft_server.1.15.1.jar
--- .bat file ends ---
All this because:
service does not know how to start in a folder,
cmd.exe does not know how to start in a folder
Starting the service will produce "timely manner" error, but the log file reveals the server is running.
If you need to shut down the server, just go into task manager and find the server java in background processes and end it, or terminate the server from in the game using the /stop command, or for other programs/servers, use the methods relevant to the server.
As Doug Currie says use RunAsService.
From my past experience you must remember that the Service you generate will
have a completely different set of environment variables
have to be carefully inspected for rights/permissions issues
might cause havoc if it opens dialogs asking for any kind of input
not sure if the last one still applies ... it was one big night mare in a project I worked on some time ago.
While it is not free (but $39), FireDaemon has worked so well for me I have to recommend it. It will run your batch file but has loads of additional and very useful functionality such as scheduling, service up monitoring, GUI or XML based install of services, dependencies, environmental variables and log management.
I started out using FireDaemon to launch JBoss application servers (run.bat) but shortly after realized that the richness of the FireDaemon configuration abilities allowed me to ditch the batch file and recreate the intent of its commands in the FireDaemon service definition.
There's also a SUPER FireDaemon called Trinity which you might want to look at if you have a large number of Windows servers on which to manage this service (or technically, any service).
Since NSSM is no longer maintained, you can consider using WinSW. It has binaries that would work with or without .Net.
Basically you create an XML file and then install it. Here is a sample of a minimal XML:
<service>
<!-- ID of the service. It should be unique across the Windows system-->
<id>myapp</id>
<!-- Path to the executable, which should be started -->
<!-- CAUTION: Don't put arguments here. Use <arguments> instead. -->
<executable>%BASE%\myExecutable.exe</executable>
</service>
And then you can install and start it:
winsw install myapp.xml
winsw start myapp.xml
Install NSSM and run the .bat file as a windows service.
Works as expected
My easest way is using opensource svcbatch (https://github.com/mturk/svcbatch/) as wrapper of CMD(BAT) in sc :
sc create myservice binPath= ""%cd%\svcbatch.exe" myservice.bat"
