Fastpath OptiConnect utilizes a special device description of QYCTSOC. When an APPC conversation is directed at this device, the OptiConnect device driver redirects the conversation through the OptiConnect bus. This will bypass most of the standard DDM, DRDA®, and APPC code.
To route data requests over OptiConnect by using the Fastpath method, you need to specify the QYCTSOC keyword in the device description parameter of the DDM file. You can use either the Create Distributed Data Management File (CRTDDMF) command, or the Change Distributed Data Management File (CHGDDMF) command to add this information.
When you create a new DDM file, do the following:
OptiConnect does not specifically use the other parameters on the CRTDDMF command. However, make sure that you have specified a valid selection (either *NO or *YES) for the Share Open Data Path parameter.
When you change an existing DDM file, do the following:
OptiConnect does not specifically use the other parameters on the CHGDDMF command. However, make sure that you have specified a valid selection for the Share Open Data Path parameter.
OptiConnect, by default, will accept any value in the mode parameter of a DDM file. However, if you want OptiConnect Agent jobs to start with the USRPRF specified in the QYYCDTSU job description, then you must use QYCTSOC in the mode parameter. Any other value in the mode parameter will result in the OptiConnect Agent job starting with the USRPRF, and the job description that initiated the DDM conversation.
