Unable to load MetaData when using Read From DB within Spectrum Enterprise Designer


When opening a dataflow with a Read From DB stage in Enterprise Designer, the following error displays:
User-added image

Unable to Create SQL

Unable to load MetaData
Item count exceeds maximum [2000]

User-added image

Database not Supported.  Unable to get metadata for the specified database.


The user account has exceeded the maximum number of data sources specified, which is set to 2000 by default.


UPDATED: March 30, 2017
The maximum number of items specified is listed in the JMX console bean "JdbcDataSourceConfigurationManager".

The default value is 2000, which should be raised in the event that the "Unable to Load MetaData" error arises.
