IDERA’s Software Solutions

Idera provides many software solutions, some of which are installed on servers, others on user workstations. In this post, we will see the different kinds of licenses that are available for the users.

Test Our Trial Version

From ER/Studio, you can download our software to test them in your environment. When you go to a product page, you can get a free trial version by clicking.

How to Use the Trial Version

To use your trial version, for some products, including ER/Studio and DB PowerStudio products, you will receive an email containing a serial number that allows you to register your solution.

After installing the software, when you launch it for the first time, a registration wizard automatically opens to allow you to type the serial number and your credentials. When the registration is successful, the wizard automatically closes and the product starts.

However, if an error occurs, an error message is displayed where we currently see in the previous screenshot: Please enter a valid serial number.

Helpful Links

You also notice the different links available in the wizard which can be helpful:

1. Trouble to Connect

If you don’t have access to the internet or your machine uses a proxy to access it, the wizard can’t directly contact our servers. This following link generates a URL that allows you to download a file from the browser of your choice and then import it through the wizard to register the product.

Be careful, the registration code used is linked to the machine where the software will be used. The license will be linked to this machine and can not be used on another one.

2. Create New Account

To register the product, you need to have an Idera account. If you don’t already have one, you can create a new account with this link.

3. Reset Password

If you have forgotten the password of your Idera account, you can request a password reset using this link.

4. Contact Support

If you are unable to register your software, you can open this page to get information about our contact support and how to contact them based on the tool.

Types of Licenses

IDERA offers 3 kinds of licenses, here is the detailed information about them:

1. Workstation (WS) License

A license which is installed on a workstation, using a serial number and an Idera account (a trial version is a license of type Workstation).

2. Network Named User (NNU) License

An NNU license allows the same user to install the product on multiple machines. The licenses are hosted on a license server installed on your network and reachable from the machines where the product is installed. An NNU license is assigned for a given user.

3. Concurrent User (CCU) License

A concurrent license is also installed on a license server. Several users can share it; the first arrived is the first served until the total number of its licenses is exhausted.

Licenses and Types of Users

These 3 types can perfectly coexist in the same product deployment:

Daily and stationary users can install Workstation licenses.
Users who are moving and have a desktop and a laptop use NNU licenses.
Users who are using the product from time to time share a pool of Concurrent licenses.

NNU and CCU Hosting

NNU and CCU licenses can be hosted on the same license server. It can be installed on a Windows or Linux server. For more information on the server itself, you can browse its documentation.

Pros and Cons of Types of Licenses

In the table below, there is a list of some pros and cons regarding the different types:

	長所	短所
WS	Once registered, the solution doesn’t need to reach a server to work.	When you want to install your solution to a new machine, or transfer your license to a co-worker, you have to contact Idera Support.
NNU	You can setup the solution on several machines for a single user without purchasing additional licenses (there is a limit of three simultaneous connections per user and product). You can reassign licenses from previous to new users without contacting Idera Support.	A license server is mandatory. You have to setup your NNU licenses with the Windows logins of your named users.
CCU	Easier administration. You don’t need to specify Windows user logins to use your licenses. You don’t need to contact Idera Support to release or reassign licenses.	A license server is mandatory. This type of license is more expensive than the other two, but may simplify licensing.
