The JDBC configuration for OTK can be managed with the "Manage JDBC Connections" task in the Policy Manager, but the task cannot manage the number of connections the API Gateway to load and save policies and settings.
Are the Cluster-wide properties "jdbcConnection.pooling.maxPoolSize.defaultValue" and "jdbcConnection.pooling.minPoolSize.defaultValue" effective for the latter connections?
