Configuring the file

The configuration file for Talend SAP RFC Server is located under the $TSAPS_HOME/conf directory (where $TSAPS_HOME corresponds to the directory where the Talend SAP RFC Server has been installed). This file consists of five sections. Before starting Talend SAP RFC Server, you can configure the file to enable some additional features of the server according to your needs.

Information noteNote:
  • Talend SAP RFC Server doesn't support the SAP cluster configuration.
  • Any change of the configuration file requires a restart of the Talend SAP RFC Server.

Before the sections

  • logging.config: Specifies the log configuration file, which sets the log levels (mandatory).
  • loader.path: Specifies directories or archives to append to classpath for including sapjco3.jar. The directories or archives need to be separated with commas (mandatory).
  • named.connections: Specifies the path to the directory that holds the SAP connection configuration files (mandatory).
Information noteNote: The named.connections parameter is effective only if you have applied Patch_20210820_TDI-45536_v1-7.3.1.

Health section

This section controls the showing of health information.

  • Sets the level of showing health information, which is collected by summarizing all the HealthIndicator results (mandatory).
Information noteNote: This section is effective only if you have applied Patch_20210820_TDI-45536_v1-7.3.1.

JMS broker section

The JMS Broker section sets up the interaction with the embedded or remote JMS broker.

To enable user authentication, you need to uncomment the following four parameters and set their values. If you don't enable user authentication, the tSAPIDocReceiver component or the tSAPDataSourceReceiver component can also connect to Talend SAP RFC Server without setting the value for their user and password fields.

  • jms.login.config=conf/user-authentication/login.config: File system directory containing JAAS authentication configuration.
  • jms.login.configDomain=tsaps-domain: Domain of JAAS authentication configuration to use.
  • jms.login.username: JAAS username used to authenticate a publisher or sender.
  • jms.login.password: JAAS password used to authenticate a publisher or sender.
Information noteNote: The username and password values are used by the tSAPIDocReceiver or the tSAPDataSourceReceiver component to connect to the Talend SAP RFC Server. They must also exist in the $TSAPS_HOME/conf/user-authentication/ file. In this file, each row represents a username and a password pair, where the username value is on the left side of the equals sign and the password value is on the right side of the equals sign.

To enable the SSL transport mechanism, copy the key store file for SSL to the $TSAPS_HOME/conf folder. Then uncomment the following two parameters (the path to the key store file and the password for the key store file) in the configuration file and set their values

  • jms.ssl.keystore.path: The path to a key store for SSL.
  • jms.ssl.keystore.password: A password for a key store for SSL.
  • jms.durable.queue.replicate: Whether JMS messages should be replicated in durable queues.
  • jms.durable.queue.retentionPeriod: Retention period for JMS messages in durable queues in milliseconds (by default: 7 days).

Embedded broker section

The Embedded Broker section details the connection information of the used embedded JMS broker. If you use an external JMS broker, these values are commented out. The following lists the settings:

  • jms.bindAddress: The host address and port (ex: tcp://localhost:61616) for the JMS broker to listen for incoming connections (mandatory).
  • jms.persistent: Whether JMS messages are persisted or not. This way, the Talend SAP RFC Server keeps a copy of all IDocs received in queues named after the IDoc. This is meant to serve the tSAPIDocReceiver component in batch mode. When the receiver runs, it collects all IDocs stored in the durable queues since the last time it ran.

By default, messages are kept in the queues for up to seven days. You can change the retention period by uncommenting this parameter in the configuration file and updating its value to meet your own requirement.

  • jms.dataDirectory: File system location used by the JMS broker to persist data.
  • jms.useJmx: Sets whether or not the Broker's services should be exposed into JMX or not.

Remote broker section

The Remote Broker section details the connection information to a remote or external broker. If you use an embedded broker, this section is commented out. The following lists the settings:

  • When active, connects to a remote broker instead of an embedded one.
  • jms.reconnect.interval: Interval between reconnection attempts.
  • URLs of the brokers for failover. Broker URLs need to be provided in this form:,tcp://ip_address2:port_number2, ...).
Information noteNote: The parameter is effective only if you have installed the R2021-01 RFC server update or a later one delivered by Talend. For more information, check with your administrator.

Kafka section

The Kafka section details the Kafka connection information needed to use the streaming mode feature. It also contains settings for configuring an Azure eventhub as a Kafka cluster.

  • kafka.bootstrap.servers=<kafka_setting>: Kafka broker addresses (in the form of host:port number) separated by commas (mandatory).
  • kafka.sasl.mechanism=PLAIN
  • required username="$ConnectionString" password="{YOUR.EVENTHUBS.CONNECTION.STRING}";
Information noteNote:
  •, kafka.sasl.mechanism=PLAIN, and required username="$ConnectionString" password="{YOUR.EVENTHUBS.CONNECTION.STRING}"; are required when feature.streaming.enabled is set to true in an SAP connection configuration file.
  • For information about configuring an Azure eventhub as a Kafaka cluster, go to Quickstart: Data streaming with Event Hubs using the Kafka protocol.
