A filter for messages. When criteria set is specified, it can be used to browse, copy, move, re-route and delete messages which satisfy the selected criteria's specifications. When a message criteria record is selected to filter messages, it also applies to the Put New Message option. Message criteria are also available to set default MQMD header values when you load messages from a file (Load from File option).

Select an existing message criteria set from the drop-down list to apply to the messages. Only one message criteria set can be specified.

Full messages are required for XML and JSON views. Enable this option to load full messages when viewing data in XML or JSON format.

When this option is enabled, the following settings become available to control whether a confirmation prompt is displayed before loading the full message. Select one of the following options:

• Always: The system prompts the user before loading the full message.

• If message size in bytes >: Specify a size threshold. The confirmation prompt appears only when the message size exceeds the specified value.

• Never: The system never displays a confirmation prompt before loading the full message.

These settings decide how the system identifies messages when you copy, move, or delete them.

• Message Identity (Message ID, Correlation ID, Put Date, Put Time):
  Use this option for the most accurate selection. However, multiple messages can have the same identity values.

• Message Position:
  Use this option when many messages share the same identity values. Keep in mind that message positions can change in a queue, so the system may not allow some actions when you select multiple individual messages. You can still use the Message(s) selected menu to copy, move, or delete messages.

Full messages are needed for XML and decode views. Enable this option to allow full messages to be loaded when in an XML or decode view. 

When enabled, the system can be configured so that a confirmation prompt can appear before loading the full message.  See below Prompt options to select desired criteria.

When the Load full msg. for XML and Decode views option is enabled, the Prompt options appear. These options control whether to display a confirmation prompt before loading a full message for XML and decode views. Select one of the following options:

• Always: Before loading full messages, the system will ask the user if the full message should be loaded.
• If message size in bytes >: Specify an amount.  The prompt asking if the full message should load will only appear when the message size is larger than the size specified.
• Never: a confirmation prompt will never appear.

Provides Copy/Move/Delete options. Available when User settings is clicked or if you are in Copy/Move/Delete messages operations.

As noted in the description on the dialog, the disadvantage of selecting messages by position (the Message Position method) is that a message’s position might change within a queue.  For this reason, when you select the Message Position method, the icons for deleting, rerouting, copying, and editing are not available when multiple individual messages are selected. You can still choose to copy, move, or delete all messages using the message(s) pop-up menu.
