Connection Profiles

A single Workato on-premise agent can be used to connect with multiple on-premise applications. A connection profile uniquely identifies each one and contains configuration information required to connect to that application.

Profiles are configured in the <INSTALL_HOME>/conf/config.yml. A config file can contain profiles to a few types of systems:

• Databases
• On-premise file systems
• Java messaging service
• Apache Kafka
• Active directory
• HTTP resource

• NTLM

  Additionally, you can configure proxy servers for on-premise agents installed in a server with limited internet connectivity.

  A typical config file will look something like this:

database:
  profile1:
    ...
  profile2:
    ...

files:
  profile3:
    ...
  profile4:
    ...

jms:
  profile5:
    ...

ldap:
  profile6:
    ...

Do not use spaces or special characters in connection profile names.

Applying a new configuration

A running on-premise agent automatically applies any changes made to the configuration file. Changes to proxy server settings require you to restart the agent.

Database connection profile

Database connection profiles are located in the database section of <INSTALL_HOME>/conf/config.yml.

A database type is specified either by using the adapter property or a complete JDBC URL provided in the url property. Using the following adapter values for the respective database you are connecting to. The following databases are supported by the on-premise agent - use them as adapter values for the respective databases you connect to.

port numbers can be omitted when matching defaults for a given database type.

Here's a sample SQL server configuration for connecting to a specific instance:

database:
  sales:
    adapter: sqlserver
    host: localhost
    port: 1433
    database: sales
    username: me
    password: foobar

Here's a sample PostgreSQL database using url property in the configuration:

database:
  sales:
    url: jdbc:postgresql://sales.database:5432/sales
    username: joe
    password: Secret123
    ApplicationName: workato

JDBC connection profile

When creating connection profile to other JDBC-compatible databases, the configuration is special. These profiles require url and driverClass properties, where url is a valid JDBC URL and driverClass provides fully-qualified name of JDBC driver class for the given database. The driver class must be available on the agent's classpath; note that your agent's classpath can be extended in the server section of the configuration file:

database:
  tpc:
    url: jdbc:presto://warehouse.intra:8889/tpch
    driverClass: com.facebook.presto.jdbc.PrestoDriver
    adapter: jdbc
    user: my_user
    SSL: false

server:
  classpath: /opt/workato-agent/jdbc

On-premise files connection profile

Working with on-premise files requires you to define a file system profile in the files section. You need to specify the base folder for file access as it will be used for resolving relative paths. A folder named HR in the C:/Documents/ directory will be configured like this:

files:
  hrfiles:
    base: "C:/Documents/HR"

In another example, if wish to provide access to the employees folder in the Desktop directory, the configuration will have a file path that looks something like this:

files:
  hrfiles:
    base: "/Users/me/Desktop/employees"

JMS connection profile

JMS connection profiles must be defined in the jms section. A JMS provider is specified by provider property of a connection profile. The following JMS providers are supported by the on-premise agent:

Amazon SQS

You need the following configuration properties when connecting to Amazon SQS:

jms:
  MyAmazonProfile:
    provider: amazon-sqs
    region: <Your Amazon API region, eg 'us-east-2'>
    accessKey: <Your Amazon API access key>
    secretKey: <Your Amazon API secret>

Note that you need to make sure your SQS queue is created before sending messages.

Apache ActiveMQ

For connecting to a running ActiveMQ broker you only need to specify the broker URL:

jms:
  MyActiveMQProfile:
    provider: activemq
    url: tcp://localhost:61616

ActiveMQ broker cannot be embedded into the agent. Using any vm:// broker connections is not supported.

Apache Kafka connection profile

Kafka connection profiles must be defined in the kafka section. You need the following configuration properties when connecting to Kafka:

kafka:
  MyKafkaProfile:
    ... connection properties ...

You can provide any Kafka consumer or producer configuration properties, e.g. bootstrap.servers or batch_size.

However, some properties are overridden by the on-premise agent and cannot be configured. You will get a warning when trying to redefine a protected property. Some examples of these protected properties:

Workato Agent also supports the following (non-Kafka) configuration properties:

ssl.* options above can be used when connecting to Kafka using SSL/TLS and allows you to keep PEM-encoded certificates and private keys inside the config.yml file. Any YAML-compatible multiline syntax could be used, for instance:

kafka:
  MyKafkaProfile:
    ssl.truststore:
    |
      -----BEGIN CERTIFICATE-----
      502mPNNAYkY4a7Zu84DLCXLFurEa4BhLBqLkzC6WdTrBN9z6Rp/svTIl6VgjSTP6
      .....
      -----END CERTIFICATE-----

Note that password-protected private keys cannot be inlined.

Active Directory connection profile

Active Directory connection profiles must be defined in the ldap section. Example profile:

ldap:
  MyLdapProfile:
    url: ldap://ldap.intra:389
    base: DC=intra,DC=company,DC=co
    username: CN=company,CN=Users,DC=intra,DC=company,DC=co
    password: secret

where profile configuration properties are:

HTTP resources

The http configuration section allows configuring agent access to internal HTTPS resources:

http:
  trustAll: true
  verifyHost: true

The agent may be configured to allow accessing internal HTTPS resources which use self-signed certificates. To enable self-signed certificates set trustAll property to true.

Normally a server certificate's Common Name (or Subject Alternate Name) field should match the target hostname. If you want the agent to accept server certificates with non-matching hostname, disable hostname verification by setting verifyHost property to false (defaults to true).

NTLM connection profile

Certain HTTP resources require NTLM authentication. This can be done using a NTLM connection profile. An example profile should look like this:

ntlm:
  MyNtlmProfile:
    auth: "username:password@domain/workstation"
    base_url: "http://myntlmhost.com"
    cm_default_max_per_route: 15
    cm_max_total: 100
    verifyHost: true
    trustAll: false

The following profile properties are supported:

HTTP methods supported for NTLM connections are GET, POST, PUT, PATCH, DELETE and HEAD.
