Create mode descriptions

Mode descriptions describe the session characteristics (including the number of sessions) that are used to negotiate the allowable values between the local and remote locations. The iSeries™ mode descriptions are used only by APPC, APPN, and HPR support.

Note:
The system ships with several mode descriptions. You probably will not need to create one. You can use the Work with Mode Descriptions (WRKMODD) command to find out which mode descriptions already exist on your system.

The mode description also specifies a Class-of-Server Description (COSD) that is used if and when this mode is used to cross an APPN network.

If you need to create a mode description, do the following:

  1. Type the Create Mode Description (CRTMODD) command on any iSeries command line and press F4.
  2. Use the online help information to choose the parameter values.
  3. Press Enter. The mode description is created.

In order for APPN and HPR to choose an optimal route at any given point in time, the pre-established sessions and locally controlled parameters should be set to zero.

Notes:
  1. If pre-established sessions are not set to zero, the first time the mode is started (through session establishment or by using the STRMOD command) APPN and HPR will establish the number of sessions specified. These sessions remain up even if conversations are not active.
  2. If locally controlled sessions are not set to zero, (through session establishment, or by using the STRMOD command) APPN and HPR establish one session that will not be taken down at conversation end.
