Lynx 1.7.1 Release Notes

Prerequisites

Before installing Lynx 1.7.1, please ensure that the target system(s) meet the following requirements:

• Windows Server 2012 R2, Windows Server 2016, Windows Server 2019 or Windows Server 2022 (physical or virtual machine).

• The server on which Lynx 1.7.1 will be installed must be joined to the Active Directory domain that contains the users that will use the solution.

• Valid SSL certificate - The certificate can be issued by a public certificate authority (for example, Verisign or GoDaddy) or an internal authority (for example, Windows Certificate Services).

• Microsoft .NET 4.6.1 or greater is installed.

• License key (available from Identity Automation - please contact your account representative).

• (OPTIONAL) Microsoft SQL Server 2012, 2014, 2016, 2017, or 2019 (any edition). SQL Server can be installed on the same machine as the Lynx Server software, or on a different machine. Note: For enterprise deployments, Identity Automation recommends the use of a high-availability SQL Server environment. Therefore, for enterprise deployments, you should choose an edition of SQL Server that supports high availability.

• (OPTIONAL) Will you be using Lynx in conjunction with Identity Automation's ExactAccess (XA) product? If using Lynx with ExactAccess (XA), then Lynx must be installed on the same computer as XA Server. This is because Lynx will use the encryption components that XA Server provides to read and write encrypted data in the database. In addition, you must use a Microsoft SQL Server instance because it is required by the XA Server.

Database Update Instructions

Lynx 1.7.1 can be configured to use an embedded database or a Microsoft SQL Server database. If you are using the embedded database, then no further action is required. If you are using a Microsoft SQL Server database, then you must upgrade the database to support Lynx 1.7.1, if you are upgrading Lynx from 1.5.0. Follow these instructions to upgrade your SQL Server database.

1. After the installation or upgrade to Lynx 1.7.1, open the Windows Services app (services.msc) and find the HealthCast Lynx service in the list.
2. Stop the HealthCast Lynx service.
3. Double-click the HealthCast Lynx service to open its property pages.
4. Click the Log On tab.
5. Select the This account radio button and enter the credentials for an account that has read and write privileges to the Lynx database on SQL Server.
6. Click OK.
7. Next, start SQL Server Management Studio (SSMS)
8. In SSMS, open the C:\Program Files (x86)\HealthCast\Lynx\CreateDb.sql file.
9. In the CreateDb.sql file (now opened in SSMS) change the top line from use [YOUR-DATABASE-NAME-HERE] to contain the correct Lynx database name. Typically, this would look like this: use [Lynx] although your database name may be different.
10. Run the CreateDb.sql file within SSMS.
11. You will notice several errors that all say that certain objects (tables) are already created. You can safely ignore these errors.
12. Now start the HealthCast Lynx service which was stopped in Step 2 of these instructions.
13. The database update is now complete.

Upgrading from Lynx 1.6.x

Lynx 1.7.1 can be upgraded directly from 1.6.x (1.6.0 & 1.6.1) versions without any issue. The upgrade process also do not require any special instruction to update the Lynx database and the data also persists in the existing database.

1. Assuming that we have already Lynx-1.6.x is installed and to upgrade it to Lynx-1.7.1, we have to install the latest Lynx build i.e. Lynx-1.7.1.29 by double clicking on the setup file.

2. It may display a dialog box stating that the reboot is required and we have to click on OK button to move forward, as displayed in the following image.

   

3. After completing the Lynx-1.7.1 installation we have to restart the HealthCast Lynx service from Services as highlighted in the following image.
   

4. Then run the Lynx portal in web browser as displayed in the following image and it displays the current installed version in the top and bottom of the login screen of Lynx.

   

5. We can also verify the upgraded version from the Control Panel > Program & Features list that the current installed version is changed to 1.7.1.29, as displayed in the following image.
   

6. So, in this way we can easily upgrade the Lynx from 1.6.x to 1.7.1 version.
