Resolution

Release 12.0 has a new feature that gives you the ability to disable locally and/or remotely initiated transfers on servers. The config member parameter which controls which transfer types the server can process is TRANSFERS_ALLOWED. This parameter is used to enable or disable processing of locally or remotely initiated transfers.

The values for this parameter are:

ALL - All transfer types are allowed to be processed.
LOCAL - The server only processes locally initiated transfer requests.
REMOTE - The server only processes remotely initiated transfer requests.
NONE - The server will not process any transfer requests.
Default: ALL

The value of the parameter can also be modified at any time by issuing the DFLT,TRANSFERS_ALLOWED command on the CA XCOM Data Transport server. 

 

Additional Information

See additional information in the XCOM 12.0 online documentation.

If you also need to disallow remotely initiated receives In this case, the only option is to code user EXIT07.  It gets called with all of the transfer parameter values after they have been read and parsed.  It then can set a return code determining whether the transfer is permitted or failed.
