How to uninstall H2 Database from Ubuntu and windows machine? - h2

How we can uninstall H2 Database from Ubuntu and windows machine? I search a lot but nothing worked for me. Please provide solution for both OS's.
Update: I've had followed http://interface101.blogspot.in/2013/12/3-steps-to-run-h2-database-in-ubuntu.html link for installation of H2 server on Unubtu 14.04, but unfortunate no one provides uninstall information.

The installation instruction you used was to just download the jar file of H2.
To uninstall, you just have to remove the jar file (rm ...).

How to upgrade pgAdmin 4 on windows?

I installed pgAdmin 4 as part of the postgres installer for Windows. pgAdmin is now telling me there is a newer version (4.8, > 4.5 which I have). However, there is no built in upgrade functionality that I can see, and when I went to download and run the pgAdmin 4 installer to upgrade, it installed itself in the wrong place, leading to problems.
At first I tried installing it to the default location (C:\Program Files (x86)\pgAdmin 4\v4), which was incorrect, because the previous installation (from the postgres installer) went to a different location (C:\Program Files\PostgreSQL\11\pgAdmin 4).
The second time, I pointed it to my existing install of postgres (C:\Program Files\PostgreSQL\11\pgAdmin 4), but it installed itself to a subdirectory there instead (C:\Program Files\PostgreSQL\11\pgAdmin 4\v4), rather than upgrading the existing installation, once again yielding to duplicated installations and problems arising from that. I assume if I go download the postgres installer, it will just reinstall version 4.5 of pgAdmin, though I have not tested this.
What is the correct method for upgrading a pgAdmin instance originally installed by the postgres Windows installer?
I think the best option is to go to Program and files -> Select PostgreSQL and "Uninstall".
Uninstaller will ask you if you want to uninstall the whole application or only individual components. Select individual components and then select pgAdmin.
This will uninstall pgAdmin from PostgreSQL directory.
From now, install the latest version pgAdmin only from official website which will install it into: C:\Program Files (x86)\pgAdmin 4\v4
If you Download the installer from here https://www.postgresql.org/ftp/pgadmin/pgadmin4/v4.8/windows/
It should automatically install the 4.8 version in (C:\Program Files (x86)\pgAdmin 4\v4)
overwriting any existing 4.x version but keeping your server connections and setting.
In your case, the previous install was in a different place, therefore, you ended up having 2 versions.
What I suggest to you is go to control panel and uninstall from there all the versions you have. After that go to the above link, download and install the v4.8 in the default location. Every time there is a new version available just install it and let the installer install it on the default location.
Please note that your pgadmin server connections can be found in %appdata%\pgAdmin.
Note that I have personally just upgraded from v4.5 to v4.8 using this method (installing it in the default location) and it worked like a charm.
Not sure the best approach here.
If you update directly pgadmin from: https://www.postgresql.org/ftp/pgadmin/pgadmin4/v4.10/windows/ the installation goes into
"C:\Program Files (x86)\pgAdmin 4\v4\runtime\pgAdmin4.exe"
Wheras the installation of the whole EnterpriseDB Installer from:
https://www.enterprisedb.com/downloads/postgres-postgresql-downloads is installed here:
"C:\Program Files\PostgreSQL\11\pgAdmin 4\bin\pgAdmin4.exe"
This looks like a wholly undesirable conflict? And leads to the problem identified by #Anomaly ?
To anyone finding this post (like me), before uninstalling your current pgAdmin 4, be aware that there may be limits on compatible versions based on your version of PostgreSQL. Following the instructions by Claudio Corchez, I removed my existing pgAdmin 4 and downloaded the latest 6.15. When I attempted to install it, the installer informed me that this version was not compatible with my version of PostgreSQL 10.3. So, I headed back and downloaded 4.30, which is now running. Unfortunately, it warns me each time I run it that a newer version is available. I just need to upgrade my entire PostgreSQL installation.
I had the same issue previously, and had to manually select the path.
Apparently now (v. 4.25) it auto-detects the path and updates correctly.
I had to download from the website, there was no update button embedded in pgAdmin itself

Websphere application server on Bluemix — install APAR fix

How can I install an APAR fix (temp fix) to the WAS on Bluemix?
Is there any documentation to teach me how to do it?
I cannot find the installation manager in the Linux OS, but even if I have it, how would I install the fix using ssh mode?
You should be able to find the Installation Manager in the /home/virtuser/IBM/InstallationManager directory [1]. Any fixes must be installed as virtuser. Once you're in the appropriate IM directory, it should be business as usual for using the imcl install command. The link below should reference additional IM documentation.

Uninstall Xampp (Windows 7)

I have some problems to access phpMyAdmin (Access denied) so I think that my XAMPP was not installed correctly. I want to uninstall this programm but I don't know how. I don't find the uninstall file in my C:/xampp, I don't find the programm in CCleaner, and I don't find the programm in the uninstall panel of Windows. It seems that the programm doesn't exist but I can run it and access localhost. So I don't know what to do, please help !
According to Xamp documentation :
If you installed XAMPP using the installer version, please use the Uninstaller. The Uninstaller will delete all XAMPP entries from your registry and it will uninstall some installed services included with XAMPP. We highly recommend that you use the Uninstall program for removing XAMPP installations from the Installer version.Please backup all the data you want to keep before uninstalling XAMPP.
If you installed XAMPP using the ZIP and 7zip versions, shut down all XAMPP servers and exit all panels. If you installed any services, uninstall and shut them down too. Now simply delete the entire folder where XAMPP is installed. There are no registry entries and no environment variables to clean up.
Hope it helps! :)

I have apache2 installed twice, need to uninstall one

During my newbie phases I was not aware that Max OSX had appache2 installed by default.
I manually installed it and now I have two versions running and it's extremely confusing, because at times I don't know to which version my developments point to. As of now, I have two version in the following locations:
/etc/apache2/ (I believe is the default installation)
/opt/local/apache2 (I believe this is the one I manually installed)
How do I uninstall version 2 (the one I manually installed)?
Thanks!
Being that it's in /opt, the directory MacPorts uses, have you tried port uninstall apache2?

Installing Subversion on top of already installed Apache?

I have a working WAMP environment (Apache Friends). I decided to try Subversion and downloaded CollabNetSubversion-server-1.6.9-1.win32.exe. On the download page there were packages including Apache server which I did not use - because I didn't want to replace my current Apache installation.
I just installed the one that did not include Apache, and now I want to configure it to work with my current Apache. What should I do?
Is there an easy step by step tutorial to explain this?
There's lots of tutorials such as the XAMPP (apache friends) version http://serk01.wordpress.com/2008/09/21/how-to-create-your-own-home-svn-repository-with-xamppapache/ and the WAMP version http://www.reloadedpc.com/other/setup-wamp-svn-subversion-windows/
If all you want to do is create a repository and do checkins and updates locally on your windows machine then just install TortoiseSVN. Tortoisesvn only installs the shell extension for windows explorer, not any command line svn executables. To get those you have to download them separately and make sure they're the same version of svn that tortoise uses or you'll get errors about version mismatches when using the command line svn.
