This question may sound absurd as I am totally new to XMPP & Openfire. I have a setup of Openfire 4.2.3 in Ubuntu 18.0.4 LTS that being used in my android chat app. During testing I received a Timeout error. While investigating the issue I found the solution rely on the XMPP updated version, check this link for more info.
Well I tried my best to find out my XMPP version and how to update it. Unfortunately I didn't find anything on it. So, I have two obvious questions here:
How to check XMPP version my Openfire is running on?
How to update XMPP version on my existing Openfire setup?
Since you are able to use the web-interface, just log in. On the start page look for the server properties. Theres the version.
For upgrading follow these steps:
To stop openfire on ubuntu: /etc/init.d/openfire stop;
Backup copy of the openfire installation directory: /usr/share/openfire;
Backup Openfire Base in Postgres: If you use the pgAdmin application, right-click on openfire base and click “Backup”. To run backup, it can be with own postgres as user. I recommend tar format, and encoding “SQL_ASCII”.
To install the new version: you can actually use the “dpkg -i” command, you will be asked if you want to keep your current version (choose this one), but you will still upgrade (option N or O - keep your currently -installed version).
On the java, has a statement informing that from version 4.3 will be necessary Java 8 installed.

And if you really meant the "XMPP-Version". There is not really such a thing. XMPP is implemented to a different extend on different server-providers. Some have more extensions, some less.
To see which ones you have, refer to the wikipedia site:
https://en.wikipedia.org/wiki/Comparison_of_XMPP_server_software
I have downloaded SQL Developer, but I can't login.
The error is:
The Network Adapter could not establish the connection.
Some pages recommend downloading Oracle Instant Client for MacOS, but I don't know how to configure it.
In order for SQL Developer to run, you should install JDK 1.8 or higher - did you do that? If not, here it is. As you've already downloaded SQL Developer, just double-click the icon and - hopefully, it'll work.
I want to upgrade a moodle website currently on version 2.5 to the latest version.
I need to clarify that is it possible to upgrade Moodle 2.5 directly to Moodle 3.3.
OR
As mentioned in the moodle upgradation document
"Note: You can only upgrade to Moodle 3.0 from Moodle 2.2 or later. If upgrading from earlier versions, you must upgrade to 2.2 as a first step."
I can only upgrade to Moodle 3.0.
Please confirm.
Thanks in advance.
In order to upgrade Moodle 2.5 to 3.3, start by backing up your site. This includes:
The Moodle files.
The Moodledata files.
The Moodle database.
Make sure you have everything and that no errors occurred while you were backing it up. If you want to be extra sure, restore it to a different location, maybe even locally on your computer and get it working there. Don't forget to adjust the settings in the config.php file as well as running the Moodle Search and Replace tool (it is not in the Moodle menus). Once you are sure that everything is working, and you still have the original unmodified backup files, you are ready to move on to the next step.
Verify your web server environment
Make sure your web server meets the hardware requirements for Moodle 3.3. Note the changes, especially in memory requirements from 2.5 to 3.3. Also make sure your server meets the software requirements for Moodle 2.7. In fact, when upgrading, it is best to verify the software requirements for every version of Moodle you will be skipping in order to find out which system components you will need to be add before proceeding.
Also, before you get started, make sure any 3rd party plugin and themes added to your site will be compatible with Moodle 2.7 and Moodle 3.3. If not, you will need to upgrade these first. If they are not available for the newer releases of Moodle, check with the maintainer of the plugin/theme to see if there might be an updated version forthcoming. If not, you will either need to fix any problems in the code yourself that may come up, switch to another similar plugin that provides similar functionality or remove the plugin completely.
Re-creating .git
The easiest way to upgrade Moodle is using Git. If Moodle was not installed using the "git clone" command, your installation will likely be missing the .git directory. You can check this by using the "git status" command. If you already have a .git folder, you can skip this section and go straight to Upgrade to Moodle 2.7. Otherwise, here is how you can re-create it:
Take note of the build date for your current Moodle installation. You'll find this on its Notification page near the bottom of the page.
Re-create your .git folder using the following commands:
# git clone a new copy of Moodle into another location
git clone git://git.moodle.org/moodle.git
# Checkout Moodle 2.5 (the version of your current site).
cd moodle
git checkout MOODLE_25_STABLE
Look through the log for a weekly release that is dated the same as your build number. The build number is a date in the following format: YYYYMMDD. Take note of the related commit number.
Next, rollback the files to the commit number of the build. Replace "56e05fced" with the actual commit number.
git reset 56e05fced
Once this is done, copy the just the .git folder into the web root of your current Moodle site.
Upgrading to Moodle 2.7
Before you get started, make sure any 3rd party plugin and themes added to your site will be compatible with Moodle 2.7. If not, you will need to upgrade these first.
git checkout MOODLE_27_STABLE
Login to your website as an administrator. You should see prompts that will guide you through the process of upgrading Moodle.
IMPORTANT: Up to this point, you could just roll back the files and everything should be back to the way it was. Once you move beyond this point, the only way to revert your website will be to delete the whole site and restore the backups you made earlier of your site's files and database.
Follow the prompts to upgrade the database. Be prepared as you may need to upgrade some of the plugins as well or make some upgrades to your web server and/or database environment.
Once you have everything running again, it will be time to upgrade to Moodle 3.3.
Upgrading to Moodle 3.3
Have you upgraded to Moodle 2.7 yet? If not, go back and complete that step first. Don't forget to make sure your web server meets the hardware requirements for Moodle 3.3.
Make sure your server meets the software requirements for Moodle 3.3 in order to successfully complete the upgrade from Moodle 2.7.
Next, upgrade Moodle from 2.7 to 3.3:
# Enable version tracking so that it is easier to upgrade Moodle in the future.
git branch --track MOODLE_33_STABLE origin/MOODLE_33_STABLE
# Upgrade Moodle to version 3.3.
git checkout MOODLE_33_STABLE
As you did before for Moodle 2.7, Login to your website as an administrator. You should see prompts that your database is about to be upgraded. If not, go to the Notifications page under Site Administration. Follow the prompts again to upgrade the database. As before, be prepared as you may need to upgrade more plugins and themes, and will likely need to make some upgrades to your web server and/or database environment.
That's it. If you followed the above instructions, your Moodle 2.5 site should now be upgraded to Moodle 3.3. To get the most out of your upgraded site, be sure to at least read the New Features page for each version of Moodle from 2.6 to 3.3.
To upgrade your site to newer bug/security release of Moodle 3.3, you will need to repeat some of the instructions. Essentially it will involve:
Backing up your site files (moodle and moodledata) and database.
Using the "git pull" command from within your Moodle folder.
Logging in as an administrator and following the upgrade prompts from the Site Administration > Notification page.
Verifying that everything on your site still work as expected.
Bug and security fixes come out every week but are only officially release every 2 months.
Hope you find this information useful.
Best regards,
Michael Milette
Per the upgrade documentation for 3.3 it says "You can only upgrade to Moodle 3.3 from Moodle 2.7 or later." https://docs.moodle.org/33/en/Upgrading
So you must first do an upgrade to v2.7 before you can do an upgrade to v3.3
Also note in the v2.7 upgrade documentation it says "You can only upgrade to Moodle 2.7 from Moodle 2.2 or later." https://docs.moodle.org/27/en/Upgrading
Personally I have found less problems when I do upgrades in smaller jumps. So in your case 2.5 to 2.7.20 is a requirement. In theory you could then go from 2.7.20 all the way to 3.3 but you may want to consider 2.7.20 > 3.0.10 then 3.0.10 > 3.3
I can say that I have actually upgraded Moodle 2.3, and Moodle 2.5 successfully to 3.x, though not 3.3 specifically.
That being said, you have to also take the following considerations:
Are you up to the minimal PHP version? (5.6.something)
Do you have the new modules required by 3.x version (3.3 added a few I think)
Are your modules ready for 3.x?
If you aren't sure of any of these, I would go grab a Vagrant/VirtualBox/Docker setup of Moodle, stage your current site (i.e. install it with the same software you have installed on your production server), and upgrade it locally to ensure everything goes as planned.
First you backed up before any moodle 2.5 upgrade.
Then download new moodle 3.3
After then unzip folder
go to xampp->htdocs->your project
paste and override new folder
Copy your old config.php file back to the new Moodle directory
Sometimes, the environment may cause issues, sometimes the Moodle versions. I have faced both. But managed to upgrade. Last time for upgrade to 3.9.2 installed the old version to local server for reference and did a clean install on the cloud. I have upgraded Moodle 2.x to 3.2 for a couple of institutions. Please feel free to contact if needed.
Few steps to consider in this
Take backup of Moodle app, Moodledata and DataBase
You have to follow the upgrade process twice
First you need to upgrade from moodle 2.5 to moodle 3.0
Now you can upgrade you new moodle 3.0 to moodle 3.3
I've installed Odoo 9.0 on Ubuntu 14.04, and I've activated the developer mode to install module from App Store. Every app I try to install that doesn't belong to the 31 apps offered by default without accessing developer mode, I get this error:
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
It looks like this happens only on the local installation. i tried to install the Barcode app in online trial, and I encoutered no problems.
If anyone may help me, I'll be eternaly grateful.
Anyway, I'm pretty sure that the app on the "App store" provided in Odoo (not the ones that is possible to download in zip and add to addons), are only for the enterprise version.
I tried in a lot of computers and different installation with no luck.
Still happenning as of today. I've been able to manually install the module I wanted:
Go to the app store web site: https://apps.openerp.com/apps/modules
Search for and download your module
unzip the archive in the addons directory of your odoo installation
Go in odoo, settings, update modules list
you can then look for it in Local Modules. You may need to remove all filters. I've done this in v8.
i am going to use BIRT plugin in eclipse in my linux operating system.
I want to know that whether there is any issue if multiple users use that plugin at the same time?
if so, what are the issues in using it?
if not, please tell me how many user can use that plug in at the same time?
please help.
As long as Eclipse is installed correctly for a multi-user system there should not be a problem.
See this entry in the Eclipse help for install information: http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fmulti_user_installs.html
