Database Connection - Camunda 7.9.0

I need to connect my database do camunda 7.9.0 (I need to use this version) but it’s not working. I’m setting the connection in server.xml but Im not sure if its this is the right file (camunda-bpm-tomcat-7.9.0\server\apache-tomcat-9.0.5\conf). Can someone help me? It’s like this

name=“jdbc/ProcessEngine”
auth=“Container”
type=“javax.sql.DataSource”
factory=“org.apache.tomcat.jdbc.pool.DataSourceFactory”
uniqueResourceName=“process-engine”
driverClassName=“com.microsoft.sqlserver.jdbc.SQLServerDriver”
url=“jdbc:sqlserver://myserver;databaseName=mydbname”
defaultTransactionIsolation=“READ_COMMITTED”
username=“user”
password=“password”

Did you use the downloaded distribution together with Tomcat?
Then the server.xml is the correct file to configure the database connection.
Do you get an exception? Or is it still using a H2 connection?
There should also be a bpm-platform.xml in the conf directory with this line inside:

<datasource>java:jdbc/ProcessEngine</datasource>
