Accepted Solution Posted: 1 year agoCesarP76 Accenture replied to CesarP76Resolved! After read this post: https://community1.pega.com/community/pega-support/question/direct-database-access-pega-applications The problem was that I didn't added the 2 jdbc entryes on tomcat application server. The following code was added to context.xml: <Resource name="jdbc/PegaRULESReadOnly" auth="Container" type="javax.sql.DataSource" driverClassName="org.postgresql.Driver" url="jdbc:postgresql://localhost:5432/pegadb" username="admin" password="pega" maxActive="10" maxIdle="5" maxWait="5000" /> <!-- name="prconfig/database/databases/PegaRULES/PegaRULESReadOnly" --> <Environment name="prconfig/database/databases/PegaRULES/PegaRULESReadOnly" value="java:comp/env/jdbc/PegaRULESReadOnly" type="java.lang.String" /> <!-- name="prconfig/database/databases/PegaDATA/PegaRULESReadOnly" --> <Environment name="prconfig/database/databases/PegaDATA/PegaRULESReadOnly" value="java:comp/env/jdbc/PegaRULESReadOnly" type="java.lang.String" /> My final context.xml and prconfig.xml are attached to show the solution. After this configuration, Query Runner worked on Designer Studio.
