Database intialization failed
Asked by Moisha Moisha:

I have installled Confluence server, started it and accessed it via browser.

Server asked me for licence and started create database.

Database createon failed on function sendError.

Now I can not retry or do something elese from web interface cause browser goes to page http://localhost:8090/setup/setupembeddeddb-default.action and shows emty page with Atlassian logo only.

How can I reset server manually to default state and try again with creating new database?

Error.log contents:

SLF4J: Class path contains multiple SLF4J bindings.  
SLF4J: Found binding in \[jar:file:/C:/Users/%d0%90%d0%b4%d0%bc%d0%b8%d0%bd%d0%b8%d1%81%d1%82%d1%80%d0%b0%d1%82%d0%be%d1%80/AppData/Local/Temp/1/e4jFBAC.tmp_dir1603434134/user/slf4j-jdk14.jar!/org/slf4j/impl/StaticLoggerBinder.class\]

welcome to the Atlassian Community!

In [a similar post](https://community.atlassian.com/t5/Confluence-questions/Confluence-6-15-4-installation-setup-error/qaq-p/1086729) here in Community the root case was that the (virtual-) server had a bit too less RAM (memory) available. In case you are restricted to a quite small amount (2GB - 3GB) I'd recommend you to review if you can upgrade memory to a higher amount before proceeding.

As for your question on resetting the steps would require to move the installation directory to a different name - then you can start over.  
Information on confluence directories on a windows system [are recorded here.](https://confluence.atlassian.com/doc/confluence-home-and-other-important-directories-590259707.html)

Probably, this is only a guess from remote, it won't be needed to reset Confluence (re-install from scratch) if assigning more memory should fix the root cause.  
Information on how to [restart the setup](https://confluence.atlassian.com/confkb/how-to-restart-the-setup-wizard-after-installing-confluence-179443224.html) wizard can be found here.

In any case - please let us know on your progress.

Cheers,  
Daniel

As I understand, your Confluence Server installation was not successful and nothing other than the Atlassian logo is displayed when you try to access the instance. Looking at the errors you showed, I believe that you took them from the Catalina.out file. Is that correct?

For you to reset the installation, you can go over to your \<confluence_home_folder\> and then remove all the contents from that folder. Also drop the database you created for the first attempt at installing Confluence.

*Keep in mind that this will give you a clean slate, no data from the previous installation will be restored.*

Some interesting documentation for this process:
> * [++***\[Confluence Data Center and Server\] Confluence installation guide***++](https://confluence.atlassian.com/doc/confluence-installation-guide-135681.html)
> * [++***\[Confluence Data Center and Server\] Confluence Home and other important directories***++](https://confluence.atlassian.com/doc/confluence-home-and-other-important-directories-590259707.html)

Even though you asked us how to reset your Confluence install, I would like to know more about the situation in which your instance currently is in. Here we go:
> 1. Are there errors after instance start up in your Atlassian_confluence.log file? You can find this file under \<confluence_home\>/logs
> 2. What happens if you access localhost:8090, with nothing after the 8090 port number?
> 3. What version of windows are you using?
> 4. Did you use the installer or the manual install method to install confluence?

Let us hear from you!
