Replicate Cluster Nodes for Proficy Authentication and Configuration Hub

This topic describes how to replicate nodes for Proficy Authentication and Configuration Hub in a failover setup.

About this task

In a failover setup, you have to create and maintain identical instances of a computing node. These steps ensure that if the primary node fails, the replica (duplicate node/s) is ready to take over.

Procedure

Copy/Paste Database Password from Latest to Previous Installation:
  1. Copy DATABASE_PASSWORD key value from the latest installation.
    1. Log in to the node (in a cluster) where the latest installation was performed.
      In our example scenario, it is Node2.
    2. Open Registry Editor.
      On the Windows taskbar, type regedit in the search box, then select Registry Editor (Desktop app) from the results.
    3. Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\UaaTomcat\Parameters.
    4. Open the Environment key.
    5. Copy the DATABASE_PASSWORD value.
  2. Paste DATABASE_PASSWORD key value to a previous installation.
    1. Log in to the node (in a cluster) where you performed the first installation.
      In our example scenario, it is Node1.
    2. Repeat steps 1-b, 1-c, and 1-d.
    3. Paste the DATABASE_PASSWORD value to overwrite the existing value.
Copy/Paste UAA.yaml from Latest to Previous Installation:
  1. Copy the UAA.yaml file from the latest installation.
    1. On Node2, navigate to C:\ProgramData\GE\Proficy Authentication\uaa-config.
    2. Copy the UAA.yaml file.
  2. Overwrite the UAA.yaml file in the previous installation.
    1. On Node1, navigate to C:\ProgramData\GE\Proficy Authentication\uaa-config.
    2. Paste the UAA.yaml file copied from Node2.
Copy/Paste Security Certificates from Latest to Previous Installation:
  1. Copy the security certificates from the latest installation.
    1. On Node2, navigate to C:\Program Files\GE\Proficy Authentication\httpd\conf\cert.
    2. Copy the server.crt and server.key files.
  2. Overwrite the security certificates in the previous installation.
    1. On Node1, navigate to C:\Program Files\GE\Proficy Authentication\httpd\conf\cert.
    2. Paste the server.crt and server.key files copied from Node2.
    3. After copying the certificates (to Node1), change server.crt file extension to server.pem.
    4. On Node1, open Certificate Management Tool from the desktop shortcut.
      Update the following field values as described:
      Certificate File Select the server.pem file created in the earlier step (refer to step 6-c).
      Key File Select the server.key file.
    5. Select Import to import the files.
    6. Select Close to exit.

Results

After completing the steps, you should have successfully replicated the nodes, ensuring synchronization between them.
