An ODBC (Open Database Connectivity) Connection exposes the LabKey schema and queries as a data source to external clients for analysis and reporting. This enables users to continue outside tools they may already be using
with data stored in LabKey.
Encrypting ODBC connections using Transport Level Security (TLS) is recommended for all deployments and are supported for both hosted and on-premise servers. Secure ODBC connections can piggyback Tomcat's TLS configuration (both certificates and keys), or the server can automatically generate a key pair and self-signed certificate. This topic describes how an administrator configures LabKey Server to accept ODBC connections.
Basic ODBC Connection Setup
Your server must include the connectors
module to support ODBC connections. They are disabled by default; to enable them, follow the instructions below.
- Select (Admin) > Site > Admin Console.
- Under Premium Features, click External Analytics Connections.
- On the page Enable External Analytics Connections, place a check mark next to Allow Connections.
- By default the server will listen for client requests on port 5435. If desired, you can change the port number within the range: 1 to 65535.
- The other settings on this page are described in the next section.
- Click Save.
Secure ODBC Using TLS
To require that ODBC connections are encrypted, you can check the box for Require TLS for encrypted connections
. In this section you learn how to configure the LabKey Server deployment. LabKey Server can either get its configuration from Tomcat's HTTPS settings, or use a self-signed certificate. The page also shows the expiration dates for the available certificates.
Using Tomcat's HTTPS Configuration
For details see Installation: Tomcat Configuration
and Creating & Installing SSL/TLS Certificates on Tomcat
LabKey Server will use the certificateKeyAlias, certificateKeystoreFile, certificateKeystorePassword, and certificateKeystoreType attributes on the <Connector><SSLHostConfig><Certificate> element to configure its TLS connections. It does not support using the certificateFile, certificateChainFile, or certificateKeyFile elements.
If you have specified protocols and/or ciphers on the <Connector> or <Connector><SSLHostConfig> elements, LabKey Server will use them as well. While Tomcat supports both commas or colons as the delimiter for the ciphers list, to make it work with ODBC connections, a colon delimiter must be used in separating cipher suites. For example:
Using Auto-Generated, Self-Signed Certificate
- Choose the validity period for newly generated certificates. The server will automatically generate a new certificate when the old one expires.
- Check the box to Regenerate certificate to force the server to generate a new certificate immediately.
- Click the (download) link to download the certificate.
- Click Save.
