Worklight Direct Update stuck in download loop

Question

I am using Worklight 6.0.0.1, my application uses wlInitOptions, connectOnStartup and checks if there is any update on the server.

The Direct Update feature is behaving weird, sometimes the application gets updated properly and sometimes it keeps on downloading and unpackaging the application over and over. So far I have not found any solution to it, I have made sure that my Worklight Studio version is same as Worklight Server version.

This happens on both Production and Test servers, I have followed both options, i.e. only Uploading the WLAPP file and in another try I re-installed the WAR file, re uploaded the WLAPP file, but still the problem persists. My production has two servers, both separate, and connected to a load balancer with sticky sessions enabled. My test has ONE server, connected to load balancer.

I am using DB2 as a local database for all 3 servers. Surprisingly Worklight Studio (Development) works perfectly fine. The problem is for both Android and iOS.

Below are the steps I am following:

1. Import the project in my Worklight Studio (Desktop)
2. Build and Run on local machine
3. Deploy all the adapters
4. Build and Run on local machine
5. Verifying functionality
6. Change the authenticationConfig.xml to use Console authentication (I use the same file every time with same username password)
7. Change the worklight.properties to point to production server
8. Provide console.username and console.password
9. Build for Remote Server (provide the URL of production/test server) 10.Upload the application on the worklight console
10. Try opening the application.
11. First time Direct Update works fine, if I follow the same steps , on the next update it starts going in download and unpackage loop.

Anyone else experiencing the same ? any workarounds/solutions?

Answer 1

A problem regarding Direct Update in a clustered production environment was recently fixed, and looks like it may also be related to purported issue in this question.

If you are an IBM business partner or customer, I suggest that you will notify your IBM contact person about receiving the latest iFix for Worklight 6.0.0.1, or wait for Worklight 6.0.0.2, to be released some time February 2014.
