API Developer Portal: API Legacy Portal 3.5

1. If you have implemented the steps for Installing the new Portalman in API Portal for CR3 and above at line 355 you will find JDBC connection

2. If this JDBC connection is broken you will see Error Code 500

3. From policy manager navigate to the JDBC connection local and click on test and see if it is working(most likely it will fail).

4. Check if the JDBC is pointing to the correct DB and has other properties are entered and set correctly.

Before you can publish a data API on the API Portal, the Gateway administrator must add a JDBC connection on the Gateway that points to the data source. For more information about how to add a JDBC connection on Gateway, see the Manage JDBC Connections section in the CA API Gateway documentation.
