问题
I have a question regarding updating a application on websphere application server. The application is already up and running and I just want to update the code which is packaged in a .ear file. Here is what I thought I should do:
- stop the application server.
- go to my enterprise application, select the one I am updating, and click update.
- point to my .ear file in replace the entire application radio button option.
- restart my application server.
After doing this and trying out my application, it is still running the old code, which makes me really confused. The only way I managed to get it to work is to use WinSCP, manually go to the cell directly/installedapps and replace the whole .ear folder. I dont think this a viable solution moving forward.
回答1:
To update existing enterprise application we do not have to stop the application since WAS stops the application before updating the code .
Based on the update you gave i am assuming this is a network deployment manager setup , so possibly problem is with sync is not taking place after updating the app and save .
Are you explicitly invoking sync operation after application update ? If not , i would recommend that.
Still problem persists then most likely for what ever reason nodeagent process is not invoking app expansion into installedApps folder but you can take a quick look at nodeagent systemout.log file or ffdc files to see if there is any clue about expansion process.
As a work-around you can also use EARExapnder.sh/bat tool available /profile_home/bin directory to expand the application into installedApps when the app is really updated in config/cells/cell_name/applications but not under installedApps folder.
I hope this helps. Thanks VT These opinions are my own.

I solved it. After some intense digging it seems the binary files were expanded into dmgr profile but not my correct node. After finishing the update instead of clicking save I click review and there is a checkbox to synchronize the nodes, which then did the trick.
