What is the best strategy to deploy the latest build to the AppHarbor live site without users seeing any error while the deployment is in progress. Worker process will always be restarted when you deploy a fresh build though. What is the recommended strategy here.
How does StackOverflow deploy builds or bug-fixes to the live site.
If you're currently getting errors when deploying new versions using AppHarbor, then please get in touch so that we can take a look.
Worker restarts should not cause errors as such, just some initial slowness for the first users accessing the site after a deploy. We're also working on hot-swaps so that we only switch over to the new version once the workers are all warmed up and running.

Possible ways to accomplish it:
Creating dedicated WCF service for this purpose (currently my favorite option)
Using the REST API?
Azure PowerShell?
Explanation:
Publishing a web-role cloud-service takes about 10 minutes. It's much too long during development - I try to do as much as I can offline, unit-test-ish and modular, but it's just impossible to completely avoid development cycles altogether with the VM.
Apparently, the long time is mostly a result of the machine being wholly restarted, so I'm trying to find an automatic solution, like uploading and installing the binaries.
What is the best way to accomplish it?
What do you think? would it cut at least 50% of the publishing time?
Do you expect any critical problems?
The solutions proposed below are definitely against best practices and should NEVER-EVER be used in production environment.
If your objective is to quickly test your changes in your development environment, there are two ways you can go about it.
Enable RDP and copy your modified binaries or other files directly in the appropriate folders on the VM. You could enable Remote Desktop on your web role and copy the files manually in appropriate folders.
Use Web Deploy: This will only work for web roles in your project but you could enable Web Deploy on your Web Roles and use that to make faster deployment. Please see this link for more details on how to use this feature: https://msdn.microsoft.com/en-us/library/azure/ff683672.aspx.
I have a problem that has similar symptoms to This question where adapter deployment hangs at 66% complete. As I'm not sure it's the same problem I'm starting this new question.
Using MFP 7.0.0, freshly installed on a new instance of Eclipse Luna.
I have a SQL Adapter that normally can be deployed with no difficulty, and these days if one edits the source that deployment occurs automatically.
As it happens I want to use a database only accessible via a VPN. So initially I developed some SQL scripts in the Database perspective. Using a JDBC URL of this form:
jdbc:db2://the.vpn.host:60006/STUDENT
My scripts work just fine. Now with the VPN still active I attempt to modify my SQL adapter to use that URL, automatic deployment kicks in and bingo, we get to the
Deploy Mobile First adapter (66%)
stage and nothing further happens, ever, this is not just a few minutes time-out, it will sit there for hours. As soon as I drop the VPN the deployment completes.
So my question is two-fold:
1). It seems clear that some aspect of the adapter deployment code is not resilient to network issue - it's clearly not acceptable to hang indefinitely. I speculate that this may hint at the underlying cause of the referenced question.
2). There must be some network peculiarity here. I assume that the deployment process is having trouble reaching the server when the VPN is active. How can I diagnose this?
We have recently identified and corrected the following via an APAR:
PI42968 ADAPTER/APPLICATION DEPLOYMENT TIME CAN BE EXTREMELY SLOW
The fix is now available via IBM Fix Central, so I'd like you to try this fix as I am hopeful it will help in your scenario as well.
I have an instance of Weblogic 10.3.5 running with a bunch of apps.
For some reason, the deployments page in the Admin console stopped showing the health (status) of the deployed apps (usually a green check icon). Just looks weird. Any ideas on how I can bring that back?
The apps are not running, possibly because their target machine isn't currently up. Find out what managed server they are targeted to and make sure it's running. If you want them to run on the Admin Server, you can change their targets via configuration.
some times it may happen...
First you have to make sure all the applications are running properly or not....
If any issues in deploying application or deployed application then it may show in this manner....
Exact solution to your problem is Restarting admin node
But it is better to do following steps...
Stop both admin and Managed nodes.
Start the Admin node then managed node.
Check the console...
I am have to develop an application based on Spring AOP that adds trace Id and loggers to existing application in live production.
The new aop application needs to be packaged onto jars and is to be deployed on code in production. But the production code is running on weblogic server and I don't have option to stop the already running weblogic servers.
Can any body help or give me the clue on how to introduce this new jar to the running application on weblogic.
Thanks in advance.
It's a bit late , but i found this question while searching for the same thing.
The nostage mode can help you with this,I tried it for JSP's and it works great , not sure about the jars though
These links are useful , they might help --

How do I refresh jsp's on weblogic
I'm currently setting up a new build server and I'm interested in any suggestions the community may have about software such as Hudson or CruiseControl.NET that may simplify and add additional value to the build process.
Previously I had a build server set up using custom batch files which would run msbuild and other such tools and these were triggered by subversion hooks to allow for a continuous builds to be done per branch. The idea was that eventually we would also execute automated tests and/or static analysis although we never really got that far. This server also acted as our source code repository, a test machine for web project builds, and a web server for custom dashboard and portal for developers on the team.
At this point my thoughts are to separate some of the responsibilities of the old build server and at least a Build Server which is responsible only for creating builds, a web server which is responsible for acting as the intranet style dashboard site for developers, and perhaps an additional web server as the Subversion repository. If it turns out to be better or easier to keep the Subversion code on the same server as SvnServe then I'll probably opt to place the Subversion repository on the web server but still keep the build server separate. Having no personal experience with any of the popular build server and CI solutions out there I'm curious how CruiseControl.NET, Hudson or other solutions would fit into this type of configuration. It appears that both of CC.NET and Hudson have web interfaces for example but the documentation doesn't clearly layout how this plays out with different hardware/system configurations so I'm not sure if either requires the web portion to be on the build server itself or not.
As far as technologies I'm dealing with .NET/C# based code which is a mix of Web/WinForms/WPF and we use a few separate Subversion repositories to host these projects. Additionally it would be nice to support Visual FoxPro and Visual Source Safe for some legacy applications. I would also like to get more team members involved in monitoring builds and would like to eventual have developers create build setups for their own projects as well with as much simplicity as possible. Also I should mention that I have no experience setting up a Java based web application in IIS but I do have quite a bit of experience setting up and managing ASP.NET applications so if that may make .NET based products more favorable unless I can be convinced otherwise.
UPDATE (after researching Hudson): After all the recommendations for Hudson I started looking into what is involved to get it up and running on my two Windows 2008 servers. From what I can gather the web portion (master) would run on my webserver but it seems that IIS isn't supported so this would greatly complicate things since I want to host it on the same machine as my other web applications. On the build server, I would be installing a second copy of Hudson that would act as a slave and only perform builds that are delegated to it by the master. To get this to work I would be installing Hudson as a Windows Service and would also need to install some unix compatibility utilities. Unfortunately the UnxUtils download link appears to be broken when I checked as well so I can't really move forward until I get that resolved. All of this is really sounding just as complex if not more complex than installing CruseControl.NET. For now this unfortunately leaves me to looking into CruiseControl.NET and TeamCity.
UPDATE (about TeamCity): After looking into TeamCity a little closer I realized that at least the server portion is also written in Java and is deployed in a manner very similar to Hudson. Fortunately it appears that Tomcat can be used to host servlets inside IIS although I can't find a good straight forward guide to describe how to actually do accomplish this. So skipping that for now I looked further when I ran into what looks like what might be a major snag.
TeamCity Professional edition only
supports TeamCity Default
Authentication and does not support
changing the authentication scheme.
Since windows authentication is likely the direction we will want to go, it's now looking like it might be back to evaluating CruiseControl.NET or possibly Hudson if I can get my hands on the UnxUtils and also find out more about how I can host the dashboard portion of Hudson within my existing IIS configuration. Any pointers?
UPDATE (about Jenkins): I ended up experimenting enough with Hudson that I ended up with a reasonable build server setup that I'm happy with and that can be extended to do much more if I need. Of course I went the rout of converting to Jenkins once Oracle took over Hudson and Jenkins is what I'm using today with little bits of powershell to help tie things together. I'm very happy with this approach right now and besides being Java based, Jenkins has quite a bit of support for other development environments such as .NET and MSBuild.
I'd vote for TeamCity here. Its is very, very easy to get stood up and running, integrates with all your .NET stuff without any trouble. The builds themselves are run by agents which can be on the build server or another machine depending on requirements--they could even be on a machine running an entirely different OS on a different network in a different country.
I highly recommend using Hudson. Not only will it allow you to build .NET applications on a continual basis, but you can also run code analysis and unit tests as well. It's easy to install (just deploy a WAR file to a web server such as Tomcat) and has many configuration options. There is also a large number of plugins available that you can use, many written by other Hudson users. Best of all, it is free and actively supported.
For our decision making process we started with following overview.
http://confluence.public.thoughtworks.org/display/CC/CI+Feature+Matrix
Our main objective was java, easy to configure/use even after nobody created a job for 6 months. We moved away from a old version of Cruise Control, since nobody really knew how to use it. Some of the commercial products are nice if you want to go beyond just continuous integration. Have a look and decide for yourself.
Be careful, I don't know how up to date this matrix is. So some of the projects might have implemented more functions right now.
An interesting alternative could be Jira studio by Atlasian. If you use the hosted version you don't have much on support issues and it comes with subversion, bamboo, and goodies (jira+greenhopper, confluence, crucible, fisheye). http://www.atlassian.com/hosted/studio/
I agree with Wyatt Barnett. TeamCity is the best choice. It is very easy to configure and use. Moreover, TeamCity has a Free Professional Edition. Previously we used CruiseControl.NET on our project. This is also a powerful tool, but it is very complicated and hard to understand.
What s.ermakovich said: Both TeamCity and Hudson separate the web UI from build agents. You shouldn't need to install IIS on a build agent. You'd need to install a JVM and the agent software on any build node - very straightforward.
