DataFlux Data Management Studio 2.5: User Guide

Messaging Tab

Use this tab to specify messaging options for the JMS Writer node for process jobs. These options enable the node to communicate with a JMS messaging system. For more information about the options in this tab, see Configuration Options for JMS Nodes.

If you see a set of default options when you add a new node to a job, then these defaults have been specified in a configuration file. For more information, see Set Up for JMS Nodes.

Message

Select what to write as a message: 

Fixed Text - static text string to send as message body. Alternatively, you can leave this field blank and use this node to send an EOF marker. For example, if another node in a process flow returns a certain value, this node could send an EOF marker.

JNDI Connection

Initial context factory - fully-qualified class name of the JNDI provider context factory.

Provider URL - server host and port information for JNDI connection.

Connection factory - JNDI name of the JMS connection factory.

JMS destination - JNDI name for the JMS destination.

Options

EOF Marker - This and the next option allow to define an EOF marker to set in messages sent from this node (no more messages will be sent). Can be set to one of three values: null (a message with NULL body serves as EOF); empty (a message with an empty string body serves as EOF), or value (enables EOF_VALUE option). Any other value is ignored (option is not set). This field is case-insensitive.

Values - If EOF Marker is set to value, then the message's body will be compared with the EOF Marker setting to determine if the message is an EOF marker. The comparison is a case-insensitive string comparison.
