Outbound LU specification

You can specify a defined APPC LU as the outbound LU.

The default setting for defined APPC LUs is BASE LU. Changing an outbound LU is useful because, when the outbound LU has status of disabled, IMS does not allocate the APPC conversation.

The outbound LU must be defined in the APPCPMxx member of the SYS1.PARMLIB library. To specify an LU as the outbound LU, use the OUTBND= parameter in the DFSDCxxx PROCLIB member. You can set the outbound LU by using the /CHANGE APPC OUTBND command. However, a restart sets the outbound LU to the value in the DFSDCxxx member, if specified. If it is not specified, the outbound LU is set to BASE LU.
