Replication can be configured to allow multiple OneSpan Authentication Server instances to keep their data synchronized.
The source server is the server where data is coming from, and the destination server is the server where data is going to. The replication queue holds data that is replicated between servers during the replication process. For more information about setting up replication, see Configuring replication.
Source Server tab
| Field name | Description |
|---|---|
| IP Address | This is the IP address of the source server. |
| Min Reconnect Interval (seconds) | Minimum time the system should wait before trying to reconnect to this server. |
| Max Reconnect Interval (seconds) | Maximum time the system should wait before trying to reconnect to this server. |
Destination Server tab
This tab allows you to add, edit, and delete destination servers.
| Field name | Description |
|---|---|
| Display Name | This is the display name for the destination OneSpan Authentication Server, which will appear on the Destination Servers list. |
| IP Address | This is the IP address to use to connect to the destination server. |
| Port | This is the port to use to connect to the destination server. |
| Use SSL | Select this checkbox to enable SSL for replication. |
| SSL Certificate | The SSL certificate to be used for replication. Certification authority (CA) files should be located on the same host as OneSpan Authentication Server. If your CA file is located on a network share, you need to copy the file locally before you browse to it and select it. |
| SSL Private Key Password | The private key password for the SSL certificate |
| CA Certificate Store | The CA certificate store that contains the SSL certificate. |
| Automatically Trust Certificates | If this checkbox is not selected, the certificates will be verified that they match the CA certificate stored in the certificate store/trust store before proceeding with every connection. Select this checkbox to skip that certificate verification and automatically accept and trust any certificate that is sent by the other server. This option makes connections potentially insecure. We highly recommend that you do not enable this option. |
Queue tab
| Field name | Description |
|---|---|
| File Path | This is the location of the replication queue file. If this path is changed or added, the directory must already exist. |
| Max File Size (MB) | Set a maximum size (in MB) for the replication queue file. If the file reaches this size, replication queue entries will no longer be written to the file. OneSpan Authentication Server will stop processing authentication and administration requests that result in a database update. |
| Max Retries | The maximum number of retries specifies how many times OneSpan Authentication Server should attempt to resend entries in the replication queue that failed at the destination server. |
| Retry Interval (Seconds) | The retry interval (in seconds) specifies how long OneSpan Authentication Server should wait before it attempts to resend entries in the replication queue that failed at the destination server. |
| Notify when queue file exceeds threshold | Select this checkbox if you want to receive a warning message when the replication queue file size reaches a particular file size. |
| Email Address | The target email address to use for sending the replication queue file warnings. |
| Queue File Size Limit (%) | This is the warning threshold of the replication queue file size as percentage of the maximum file size. If Notify when queue file exceeds threshold is selected and the replication queue file size exceeds this limit, OneSpan Authentication Server will send a first warning notification. Further notifications are sent in steps of 5% file growth until the maximum file size is reached. |
