 Most common databases are supported by Grails (via Hibernate), we test and run MySQL (InnoDB). [[BR]]
 The database must support transactions and row locking. [[BR]]
-A jar matching the configuration needs to be placed in the projects lib dir (e.g. lib/mysql-connector-java-5.1.7-bin.jar [http://dev.mysql.com/downloads/connector/j/5.1.html Connector])

+'''MySQL''
+
+MySQL is the database we use most often and therefore the most thoroughly test and highly recommended. [[BR]]
+Also see [wiki:InstallationTips Installation Tips]. [[BR]]
+
+'''PostgreSQL''
+
+Not tested, please email us if you have tested against PostgreSQL. [[BR]]
+We will run some tests against PostgreSQL when time permits or if requests are made. [[BR]]
+
+'''MSSQL'''
+
+Live deployment in progress (11-Jan-2010) no issues so far. [[BR]]
+
+'''Oracle DB'''
+
+Currently gnuMims will not run against an Oracle DB without some work. [[BR]]
+The known issues should be surmountable and are listed bellow:
+ * 30 Char limit, several gnuMims domain classes and attributes exceed this limit, this is possibly the biggest issue.
+ * The default sequence generator does not create Id's as expected, a suitable hibernate sequence generator needs to be set.
+ * To store empty strings the IS_NULLABLE metadata for the column needs to be set.
+ * [http://www.stanford.edu/dept/itss/docs/oracle/9i/server.920/a96540/ap_keywd.htm Oracle reserved words] ("comment" and "date") this can be solved with a mapping in the appropriate classes:
+ {{{
+    static mapping = {
+    columns {
+        comment column:'entry_comment'
+      }
+    }
+ }}}
