The GXflow licensing scheme is very versatile, it adapts to the requirements of different companies and the production lifecycle of your inbox driven applications.
This document contains two sections. The first details the license types you may use and where to store them depending on your needs. The second is specific for users that are updating systems to GeneXus 15 Upgrade 8 or higher.
Note that you don't require GXflow licenses for running a Business Process Diagram object in Prototyper Mode while you don't need to log in with different Users and Roles. So if you're just doing your first steps with GXflow you may skip this document.
The licenses can be of two different products or types, depending on your plan.
This product or plan handles nominated licenses used by GXflow.
A nominated license is a license which is associated with a specific user, and only that user can use the license.
This product or plan handles corporate licenses, which are not nominated.
A corporate license allows using GXflow in your applications without user restrictions. Any user that enters the application will be authorized when this type of license is used.
Example of how these products or types are shown in the license manager:
Please contact your distributor or Sales representative for more details regarding the plans or how your plan relates to these products or types.
Licenses can be handled with two different methods or mechanisms, each storing licenses in different locations, depending on your needs. Two options are available: Native (default) and Protection Server.
The licenses are stored in the database, specifically the one of the GXflow engine.
The licenses are stored using specific functions of the operating system, via GeneXus Protection (126.96.36.199 or higher).
The Native protection method is recommended when the application is installed on a Platform as a Service environment (PaaS) or on an environment that needs horizontal scalability; more than that, in most of those cases it is the only one that is suitable for those scenarios. Because of infrastructure and networking issues, this is also the one that is more easy to install and set up, especially in non-Windows servers (Linux, AIX, iSeries, etc).
The Protection Server protection method is recommended for development and testing stages, where licenses are shared for different prototypes and databases are temporary.
So, generally speaking, the Native is the one that is recommended for production environments and the Protection Server for prototyping.
Note for developers: License protection method is, once selected, stored in the database; so take into account that you have to set it again after operations that delete the selection (eg.: 'Create workflow tables')
All operations around native licenses are handled using the GXflow License Manager.
To use Protection Server licenses, you must change the license protection setting in the GXflow License Manager. Read GXflow centralized licenses configuration (GXflow on Windows) for more information. Then, almost all operations around Protection Server licenses can be handled using the GXflow License Manager too.
GeneXus 15 Upgrade 8 features scalability, stability and usability improvements related to GXflow, specifically to GXflow license management. Licenses can now be stored in the database to improve scalability and ability to run in Platform as a Service (PaaS) environments and a new license manager has been introduced to easily handle the licenses no matter on what environment, operating system or DBMS you are running.
The following steps will help you to update your licenses.
- Read carefully the section above "GXflow license types and license protection methods".
- Save (export) the Users before uninstalling, so you don't need to type them in again later.
- Uninstall your GXflow Client licenses
- Enter to the GXflow License Manager of your GXflow installations and choose the license protection method that fits your needs.
- Ask for Licenses
- If you own a GXflow Corporate license plan, you must ask now for
- GXflow Corporate licenses (Read the section above "GXflow license types and license protection methods").
- Gxflow licenses (Required only for systems developed with GeneXus 15 Upgrade 7 or previous.)
- Import Users
To handle this new license scheme, a new web-based license manager is used, where you can execute all the actions needed to manage GXflow licenses (Request, Install, Uninstall, Change, etc.)
This new license manager is installed as part of the GXflow Client.
Check this document for detailed information on how to work in this new license manager.
In Linux, storing licenses in the local file system is discontinued. Refer to the section "License Protection methods (Native or Protection Server)" for the new options available.
As of GeneXus 15 Upgrade 8, if you do not have GXflow licenses, you cannot log in to GXflow Standard Client using WFADMINISTRATOR user (neither with any other user) using GXflow's login panel.
Logging in to the GXflow Standard Client with WFADMINISTRATOR (or any other user) in prototyping scenarios can be useful when you want to log in using different roles.
Note: You don't require GXflow licenses for running a Business Process Diagram object in Prototyper Mode (while you don't need to log in with different Users and Roles).
When you run a Business Process Diagram object with Execution Mode property set to "Standard Client", that action opens the GXflow Standard client, so in that case you need to install at least one license to be able to log in.
Note: You can still log in using WFADMINISTRATOR via GAM's Login or via a Custom Login Panel that uses GXflow's API.
No login is required when no license is installed. As soon as at least one license is installed, a user with GXflow Administrator role (eg. WFADMINISTRATOR) can request and handle the licenses.
