Product and License Storage

License Manager by default stores all products and licenses in embedded Java database on local disk, and also it supports MySQL, PostgreSQL, and MS SQL Server database for storage. Setting can be changed with Database Storage Options menu item in Tools menu.

License Manager storage

On the left tree the default root node Database Storage is used for local or remote database database storage, Online Storage root node is used for Online.License4J storage. Online storage node is displayed when connected to Online.License4J system.

License Manager supports creation of unlimited number of categories, sub-categories and products; you can also generate any number of licenses on database storage. Online storage allows generation of maximum 1000 licenses for a single License Manager license purchased. For each additional License Manager license purchased, you will have additional 1000 license generation permission. Account information, generated product and license numbers is displayed in Online.License4J Settings menu as in the sample screen shot below.

Note: There is no license limit when License Manager is used with a database server. License limit is only for Online.License4J storage.

Product Creation

Before starting generating licenses, you should first create a product. While creating a product you need to define product name, ID and encryption algorithm to be used. You can later edit product information but can not change encryption algorithm.

License Activations

License activation settings are defined on "Activation Information" step of license generation wizard. Activation information step is detailed and includes many features. Trial license implementation is available on activation step; setting activated license generation date/time to activation time enables an easy trial license implementation. Therefore a single license with validity period set to e.g. 30 days will be enough for a software product; all users can use same trial license and their trial period starts when they activate. Hardware ID selection is defined on this step, there are four builtin hardware IDs available; a custom hardware ID can also be used.

License Manager Activation Settings Window

Manage Activations menu item in License main menu is enabled if selected license is generated with activation support. A window as in the screen shot below is displayed, and all license activations are listed. You can add or remove activations, and also modify maximum allowed activation count. Two types of activations are supported. The first one is activation code, which is a cryptographically secure license key used as activation code. The second one is a license text. Activation details and license string can be displayed with the View menu item in Actions main menu.

Activated License Modifications

License modification keys can be used to modify an already activated license on customer's computer.

Modification keys can be generated with a wizard in License Manager or with auto generation settings; templates also supported for modification keys.
