Confluence User-installed Plugins Screen Slow After Server Migration

Jonathan Martin6

We've just migrated Confluence to a new server. I'm attempting to re-install all of our plugins/add-ons. However, For some reason when accessing the "Manage add-ons" screen the "User-installed" add-ons is taking 10 mins or so to load. We never had an issue in our previous environment.

Here's some background on what I've done/researched:

Background

No errors in the logs.
Able to access System plugins on the "Manage add-ons" screen without delay.
Able to still upload plugins after waiting 10 mins for the "User-installed add-ons" section to load.
Disabled UPM using the JVM arg: -Dupm.pac.disable=true.
Able to access legacy Confluence plugin screen using this URL:
1. https://<confluence-root>/admin/viewplugins.action
2. I can upload JAR packaged plugins here but not OBR's. Also, this screen responds normally.

Here are our specs. The new environment is the same except for the database which we've migrated from MySQL to Oracle:

Specs

Windows O/S
Confluence v5.4.4
UPM v2.14.0

Just a few thoughts on what it could be or how to proceed:

We successfully migrated the data, could it be due to old plugin data from the previous environment?
Is there a way for me to enable debug logging for UPM or profile the UPM page?
Thought about upgrading the UPM plugin.

Any help would be greatly appreciated.

Some more info... We've got Service Rocket's Visibility and Redirect plugin installed. I'm beginning to think it may have something to do with these plugins and Oracle based on this: https://community.servicerocket.com/servicerocket/topics/problem_installing_reporting_plugin_4_3_2_on_confluence_5_4_4

You might try upgrading to the latest version of UPM (available from https://marketplace.atlassian.com/plugins/com.atlassian.upm.atlassian-universal-plugin-manager-plugin). Some performance improvements were made in 2.14.2, but the latest version (2.18.1) has other fixes and improvements.

It doesn't sound like these KB articles are relevant, but I'll list them here anyway:

Jonathan Martin6

Hey thanks. These KB articles sound very familiar to what we're running into. I'll give safe mode a shot... then attempt upgrading.

Jonathan Martin6

Running in safe mode didn't fix the issue. I see this in the logs... Could it be related to my cache size? Will try upgrading UPM too. However, I'd like to find the root cause first.

I missed the part in your question where you said you moved from MySQL to Oracle. This is now out of my league. You might want to raise a ticket at https://support.atlassian.com/.

I am pretty much experiencing exactly the same problem using the almost exact version numbers (mine is Confluence 5.4.1), except that in my case the database was migrated from HSQL to Microsoft SQL Server.

Did you ever find the answer to this?
