Hi Julian,

After analyzing your shared file noticed few things as follows:

1. As you specified that you are using single user there is no need for the AdminPegaRULES datasource configuration as explained in the installation guide.
2. Also i can see some issues with the PegaRULES datasource configuration and some of them are explained below,
   1. <datasource jta="true" jndi-name="java:jboss/PegaRULES" -> <datasource jta="false" jndi-name="java:jdbc/PegaRULES"
   2. jdbc:oracle:thin:@localhost:1521:pegajboss -> jdbc:oracle:thin:@localhost:1521/service-name or jdbc:oracle:thin:@localhost:1521:SID
   3. validation element also not matching with the guide specific properties, not sure whether you are using the custom validations.
3. As you are using the XA Data source the driver module name is specified incorrectly as shown below,
   1. <driver name="oracle" module="oracle.jdbc"> -> <driver name="oracle" module="com.oracle">
4. You had specified that you are using the single schema, so the rules and data schema configurations should point to single schema name as shown below,
   1. <simple name="java:/prconfig/database/databases/PegaRULES/defaultSchema" value="pegarules"/> -> here you should give your schema name
   2. <simple name="java:/prconfig/database/databases/PegaDATA/defaultSchema" value="pegadata"/> -> here you should give your schema name

Note: This information is provided based on the high level overview of your configuration file with reference to the latest Pega version as i am not aware of your version of pega. So, i would suggest you to cross check with the installation guide for the version which you are trying to install so that it will be more near to your configurations for cross verifications.

Hope this information might help you to resolve your issues.

Regards

Mahesh
