Weblogic changes cannot be activated - Timeout Error

For a few months now, I have been dealing with a lot of WebLogic 10.3.6 related frustration because I was running into an issue with updating one setting and each time I tried to activate the changes I used to run into an issue trying to activate the changes .

I have a deployment with 4 Managed Servers each of which host 4 Hyperion services load balanced across 4 VMs. These were the preliminary steps I worked with Oracle on. So, I thought these are some of the steps that we can try on our own and help accelerate the resolution process.

1. Shutdown the weblogic domain admin console then move those files out of the Pending folder and then restart the admin console and try to activate the changes again.

2. Navigate to /pending folder. In this folder, there are configuration files which are temporary config files which are cached with changes made from console. At the time of activating changes, the config.xml from the pending folder replaces the original config.xml and other configuration files inside the /config folder.  Kill the Admin Server, and replace the config.xml from the /config folder with the config.xml from the /pending folder. 

Delete all the .lok files inside like edit.lok and config.lok.  Restart Admin Server. 

3. Flush down the changes to be activated using WLST. 

You can use the below script:

4. And of course the classic, Increase Logging level. This can be again perfomed on the config.xml file.

In my case however, none of these methods helped and each time I kept hitting a roadblock . The solution was to update the Listen-address on the config.xml and to repeat the steps for all the managed servers and the components deployed on the mananged server. It is important also to follow a specific order to carry the steps below ,out. 

a. Stop all the Hyperion Services and the Weblogic service.

b. In your admin server, navigate to where the pending directory lies in this case, X:\Oracle\Middleware\user_projects\domains\EPMSystem and rename pending to pending_bkp.

c. Modify your entry in the config.xml file is in the below syntax.

Change the  to include the IP/FQDN to reflect the new entry. So, Post the change,the entry becomes,

d.After this is done for all the managed server components deployed under Weblogic, Start the Weblogic Admin server and the Hyperion Application Services.

You should be able to activate any pending changes now.
