The error message, "Oracle/xdb/XMLType" is occurring when using the Oracle JDBC drive, an oracle connection object and as data is being pushed from the VMWare Cartridge to an Oracle Database.
It happened as Foglight was upgraded to version 5.7.1. No monitoring of an Oracle database is taking place. They have loaded the connection string to the Oracle database and it fails with the error when we attempt to make the connection. This is not a monitoring issue. Data is being pushed from the VM Ware cartridge to an Oracle database.
