Request for Help

Users can ask for assistance for workflows through a dedicated features in main toolbar:

A message with a workflow definition and log file attached (more files can be added) will be prepared to be sent to ServiceDesk if DT email parameters have been provided during tool configuration.

Cloud Environment

Cloud Environment

Use this menu item to configure Cloud Environment parameters, to connect DT to erwin Cloud platform (see Running DT from Cloud Platform)

          1. Select environment parameters – erwin EA Agile or erwin EA Agile V3 – and instance

          2. Provide credentials for the selected instance

          3. Test the connection

          4. Select workspace containing the DT package (see before)

          5. Set the communications to be active or not. In last case, DT will not take charge of requests from           cloud. This may be applied as a temporary setting for upgrade/maintenance purposes etc.

          6. Select a physical folder. This will be used as a publishing folder for web reports (HTML, pdf, csv,           Excel), like web logs, workflows operation data, sequence progress reports. It has to be:

a.Readable/writable by Windows user running Windows services and the DT UI on premise

b.Published in LAN or public web, making DT reports visible and accessible by web.

          7. Save

          8. Restart Windows service “erwinDataTransformationEventManager”

          9. Reset WF/Sequences from Tools menu item.

Reset Cloud Requests

Reset Cloud Requests

Use this menu item to reset requests sent by erwin Cloud platform (see Running DT from Cloud Platform).

If DT Windows Services are forced to stop, or in the case of a severe internal error, sequences may enter an inconsistent state which could stop other jobs from being executed. In such a case, the administrator may use the “Reset Cloud Requests” item in the “Tools” menu, or request for “RESET CLOUD REQUESTS” job by cloud.


Users, Roles and Security

Users, Roles and Security

DT interacts with CM contents – models, objects and so on – through the same logic and application components that Corporate Modeler and Evolve rely on.

Normal authentication is the only fully supported option.

Windows Authentication is not supported in DT, as it is not suitable for batch job execution.  


 General rules about security, authentication and authorization are:

Users’ logon is performed using their CM userid/password, provided that a valid DT license has been installed.

Once logged on, users can define model configurations, and associated workflows, only for models which have been granted through Corporate Modeler Administration.

When a user defines a model configuration, users’ credentials of related CM Adapters (created automatically for data export/import on that model) are encrypted and stored in the CC internal database. This is needed in order to be available when workflows using those adapters are executed in a batch mode (which “Test workflow” simulates).

This means that CM Users actually executing the operation are the person that configured and saved the associated model configuration. If the user has to be changed, the new user must log on to DT, and save the configuration, in order to bind their CM credentials to it; the workflows will be automatically updated.

Read/write/delete operations on object type instances will be executed within the same user’s rights scope existing in model. This means that they are impacted by general and specific grants on model and object type, by the status of the object (for instance, Frozen level) and property type configuration (Read Only properties will be not updated).

When requested, these operations will be executed, if possible, or a log will be produced, containing details about what prevented the operation to be finalized.
