How to Use xcompre

An xcompre shell script is provided with CA XCOM Data Transport as a sample script, and is available online. It is an option to run an exit on the local system before the transfer starts. It can be tailored to meet individual user requirements. The xcompre exit collects and passes transfer ID information (tid) to xcomqm, along with the parameter values specified by the available options, -g and -p.

Note: The -g and -p options, for use with xcomqm, as shown in the sample script are intended only for use with this exit.

The pre-allocation exit is invoked after CA XCOM Data Transport receives the CA XCOM Data Transport header from the remote partner, but before the transfer commences.

For information about shells and script changes, see Shells and Script Changes in this chapter.

For remotely initiated transfers, the pre-allocation exit is invoked after CA XCOM Data Transport receives the CA XCOM Data Transport header from the remote partner, but before the transfer commences. For locally initiated transfers, the pre-allocation exit is invoked based on the value specified by the global parameter XCOM_LOCAL. If XCOMPRE_LOCAL is set, the pre-allocation exit is invoked before sending the CA XCOM Data Transport header to a remote partner.
