F6=Create

Use the Create option, or enter the CRTMQMCHL command from the command line, to obtain the Create Channel panel. There are examples of Create Channel panels, starting at Figure 55.

With this panel, you create a new channel definition from a screen of fields filled with default values supplied by WebSphere MQ for iSeries. Type the name of the channel, select the type of channel you are creating, and the communication method to be used.

When you press Enter, the panel is displayed. Type information in all the required fields in this panel, and the three pages making up the complete panel, and then save the definition by pressing Enter.

The channel name must be the same at both ends of the channel, and unique within the network. However, you should restrict the characters used to those that are valid for WebSphere MQ for iSeries object names; see Channel attributes.

All panels have default values supplied by WebSphere MQ for iSeries for some fields. You can customize these values, or you can change them when you are creating or copying channels. To customize the values, see the WebSphere MQ for iSeries System Administration.

You can create your own set of channel default values by setting up dummy channels with the required defaults for each channel type, and copying them each time you want to create new channel definitions.

Table 31 shows the channel attributes for each type of channel. See Channel attributes for details about the fields.
