1)Start Selenium server as Hub just placing a cmd : java -jar selenium....jar -role hub hubconfig.json
2) Start two appium servers as nodes for two devices as,
i)appium --nodeconfig path\to\nodeconfig1.json -p 4723
ii)appium --nodeconfig path\to\secondconfigfile\nodeconfig2.json -p 4724
3) You can call them through testng.xml as parallel tests.

hi basker,
really i am telling that i am new to appium
and i did configuration and all i am able to execute one or two programs on emulators and real devices
now my task to execute same program on two devices parallel,, and two different test case have to execute on different devices at same time
please help me how to start and what are the requirements
Hi Bhaskar,
Can you be more specific on how to create node?
I could not locate nodeconfig path.
Thanks
hi @RISHI_KHANNA ,
If you are running appium from (Appium.exe) path then ,
node appium --nodeconfig path\to\nodeconfig.json -p 4724 -bp 5724
(or) if you're doing from cmd,
appium --nodeconfig path\to\nodeconfig1.json -p 4724 -bp 5724
Note: "path\to\nodeconfig1.json" is where your node configuration json file locates...e.g. D:\file\nodeconfig.json
Json File should like as follows and please made changes according to you and pls let me know whether it works or not :
nodeconfig.txt550 (449 Bytes)
Thanks,
Bhaskar.
nodeconfig.json: This particular json file should come with node.js?
I am unable to locate this on my system
Instead of Node configuration files, you can also write the java junit/testng code pieces and invoke this java test code as parallel execution units. I don't think we require to start the Selenium Standalone servers here. Appium server has nothing to do with Selenium Standalone servers. Once two Appium instances run on two different ports, these will simultaneously test two devices at one time.
Hi,
It should not come with node.js .We have to create json file manually with .json extension.
I guess you might think of package.json (not used for Grid ).
Please save that txt file to json file and use it ,will get it resolved. (Please make sure that Selenium Hub is already in running state).
Thanks,
Bhaskar
Yes @Khushboo_Kaur ,
I agree with you. I'm able to run multiple devices on parallel with out Selenium Hub configuration. But the Appium team had mentioned http://appium.io/slate/en/v1.3.6/?java#selenium-grid469 here.
Hi,
I tried setting up the configuration but getting error "Request to register with was unsuccessful."
I tried to create two instances of appium. Started my appium.exe on two different port numbers 4720 and 4730.
Started my grid server using : "java -jar selenium-server-standalone-2.45.0.jar -role hub"
Node server1 : appium --nodeconfig C:\Users\rishi.kumar.khanna\Desktop\nodeconfig1.json -p 4730 -bp 5724
Node Server2: appium --nodeconfig C:\Users\rishi.kumar.khanna\Desktop\nodeconfig.json -p 4720 -bp 5724

Hi @RISHI_KHANNA ,
Nice to hear that you're trying and almost done...
You have to start Selenium Server as a hub with json file. have a try with the following and they're...
HubConfig.txt257 (329 Bytes)
java -jar selenium-server-standalone-2.45.0.jar -role hub -hubConfig path\to\HubConfig.json
Hope this will get resolved.
Thanks,
Vijay Bhaskar.
Hi,
Thanks for the prompt help. But still facing the same issue. Can you check my both nodeconfig files?One more doubt - while creating nodes from cmd do I need to open the appium.exe on both the ports manually?
Hi,
No need to open GUI mode Appium server because you're already done appium servers with Command Prompt with Json files. I saw your config files and they are fine.
I guess you're giving same bootstrap port number to both nodes.please have a try with different port nums.
-bp 5723 & -bp 5724
Hope will get resolved..!!!
Regards,
Bhaskar.
Its still not working. Throwing error Unexpected token. Find the screenshot- capture.
Also, we I tried creating node without passing bp and port in command line, only one appium instance was registered on hub . For second instace its throwing an error "Pleas make sure only one appium instance is running"
Screenshot- capture2
The error is coming only when you're trying to start another appium server with the same port number...and in the picture you were not given different appium port numbers and bootstrap numbers. Could you please check them once and give --udid XYZZZZZZ along with them if possible.
UDID is for iOS devices..right?
Also, m able to create grid properly now. Thanks a lot.
Now the test case is failing. Throwing null pointer exception
That sounds great.!!!! 
udid means serial number of your andriod device too... just type a command in your cmd prompt "adb devices" , you'll find a unique number for each device that is udid only.Check your log once.

Bhaskar.
Successfully created grid and node.
When executed, out of 2 tests 1 of them fail... even though device id is mentioned it is getting executed on another device. Its running only on one device at a time
Throwing an error: org.openqa.selenium.SessionNotCreatedException: A new session could not be created. (Original error: The following desired capabilities are required, but were not provided: deviceName)
Even though the deviceName is correct and same as mentioned in .json file
