Global Maps Table Columns

Column	Description
Server ID	Identifies the ID of the server where the global map variable resides.
Channel	This will either be the channel name, or "<Global Map>" if the entry refers to the global map rather than a global channel map.
Key	The string used to uniquely identify the entry within the given map.
Value	The string representation of the current value residing in the map entry. Note that although the Global Maps table will show the string representation, the actual object resides in memory on the server side. If the object has no string representation you may see an entry like "java.lang.Object@123abc"; instead.

Global Maps

The Global Maps tab allows you to view the current state of the Global Map and the Global Channel Maps specific to particular channels. For additional information on these maps, see Variable Maps. The Global Maps table shows all current global map entries, and all current global channel map entries for the channels that are currently selected in the dashboard table. You can multi-select channels to view global channel map entries across multiple channels at once. Global Maps Table Columns Parent topic: Dashboard View

Custom Metadata Columns

Custom metadata columns are user-created, searchable columns that appear in the Metadata Table in the Message Browser. As messages process through a channel, these columns are populated from the Variable Maps using a configurable map key. Column Description Column Name The name of the actual database column. This name will also be shown in the metadata table when viewing the message browser for the channel. Type The type of column to create. STRING: A textual string value. NUMBER: A numeric value. This may be an integer or floating point value. BOOLEAN: A true/false value. TIMESTAMP: A date/time value. Variable Mapping The key used to look up values in all available variable maps for each connector. As explained in the Variable Maps section, the following maps (if available) will be checked in this order: Response Connector Channel Source Global Channel Global Configuration Modifying Custom Metadata Columns Parent topic: Summary Tab

Alert Variables

alertId: The unique ID of the alert. alertName: The name of the alert. serverId: The unique ID of the server. globalMapVariable: Indicates that you can use any variable in the global or configuration maps. date: The current date, formatted as a human-readable string. systemTime: The current epoch time in milliseconds. error: The full error message, including (where applicable) the source code, line number, and error details. errorMessage: If an exception is associated with the error event, this will be the message or detail of the exception. errorType :The category of the error. For additional information, see Alert Error Types and Regex. channel Id: The ID of the channel associated with the error, if applicable. channelName: The name of the channel associated with the error, if applicable. connectorName: The name of the connector associated with the error, if applicable. connectorType: The type of the connector associated with the error, if applicable. messageId: The ID of the message

Mapper Transformer Step

This step extracts data from a field in the message (or an expression) and places it into one of the available Variable Maps. Depending on the scope of the map, this variable will be available in subsequent steps, in the destination connector properties, or even in subsequent connectors. Item Name Description Variable The variable name / key to use when inserting into the map. The Add to drop-down menu to the right determines which map to place the variable in. For additional information, see Variable Maps. Mapping The value to place into the map. This may be a field from the message, or any JavaScript expression. Default Value If the Mapping is not found or evaluates to an empty string, this value / expression will be used instead. String Replacement This table allows you to perform replacements on the value before it gets inserted into the map. Regular Expression: A Java-style regular expression to test against the value. This will implicitly set the global regex flag. Replace With:

Global Map

This map is available across your entire server, across all channels and all messages. That means you can store a value during message processing in one channel, and use that value from a different channel, or somewhere else like an Alert. You can also store global map values in the global scripts. Like the global channel map, this map is useful for storing stateful, non-serializable objects like a database Connection. It is in-memory only, meaning that if Mirth® Connect is restarted, the entries in this map are not preserved anywhere. It is also a concurrent map, which means that "null" values cannot be stored in it. Get global map value: var value = globalMap.get('key'); var value = $g('key'); Put global map value: globalMap.put('key', 'value'); $g('key', 'value'); Note: By default the "Clear global map on redeploy" option is enabled on the Server Settings Tab. You may want to disable this if you want the global map to remain unchanged when you redeploy all channels. Parent topic: Va

Configuration Map Settings Tab

The configuration map is one of the available variable maps that can be used from within channel properties or scripts. The fact that it is stored in the Application Data Directory as a flat file makes it unique. It is intentionally not included in server configuration exports. Because of this, you can use variables from this map in your channel properties, and the same channel can be used across multiple Mirth® Connect servers without having to edit the channel for each server. By default the values in the table are not immediately shown. Select Show values to reveal all of them on screen. The Configuration Map tab enables you to edit the entries in the configuration map for the current server. Double-click any of the cells in the table to edit the values. Select the Add / Remove buttons on the top-right side of the window to add or remove entries from the table. Image of the Configuration Map tab Table Columns Tasks Parent topic: Settings View
