PROD_PERM and DACS getPeList function for real and delayed symbols

We are receiving DACS response and reading data returned by getPeList which is vector of unsigned int.

We need to know how to interpret numbers, there is no information in DACS docs unfortunately. We need to know actually only one thing - whether authorization response came on actual or delayed symbol. in out case real time PE is always 5625 and for delayed symbols it is 9241.

We are using Open DACS and RFA 8.0 C++

PE can be mapped to DACS subservices which are assigned to DACS users.

For example, from the above picture. PE 5625 is mapped to LSE1D (exchange subservice) and GBSE3PRIPD (product subservice). To subscribe to the item with PE 5625, the DACS user must have both LSE1D and GBSE3PRIPD in the profile.

You can use the getPeToSubServiceList() method is used to lookup within DACS, the PE to subservice authorization values that have been assigned to the referred to service.

For more information, please refer to Tutorial 4 - Content Based Entitlements (CBE).

Hello @mktdata ,

If my understanding is correct, you are trying to understand, for each of the PEs returned per user if it is a realtime PE or a delayed PE?

The way I can think of obtaining this information, you would need to obtain a DACS lock per realtime item (for example, subscribe IBM.N), and a DACS lock per delayed realtime item (for example, subscribe delayed /IBM.N), and each will carry it's lock, you will see the PE assigned, to this item, and therefore to this type of item per exchange. The information would repeat for each type of instrument that you require, so you would need to run this once, per type of instrument required.

Perhaps not directly relevant, Open DACS Permission Server (ODPS) interface includes function itemToPE that is intended to obtain this information, to map item to it's PE(s).

Hope this info helps
