Hello EveryBody, can I install alfresco community against oracle instance, thanks
Alfresco Community can be run against MySQL and PostgreSQL. Alfresco Enterprise supports Oracle, Microsoft SQL Server, DB2 as well MySQL and PostgreSQL. Refer to summary of the supported platforms. In addition, the Enterprise version can also be run against Ingres (see below for links).
Please refer to Database Configuration
kayne zhang gave you the correct, official answer. Of course Alfresco Community Edition is open source, so you are free to add your own support for Oracle if you wish. Some folks in the community have done this in the past. Here is one example but you may be able to find others.
But if I were you, I'd stick with either MySQL or PostgreSQL.
