You REALLY need to spend a LOT of time reading manuals. From the CICS TS 5.1 RDO manual:
So unless your record key is 8 bytes or less, you CANNOT use it as the ENQMODEL name. The ENQMODEL name is arbitrary but must be the same in each CICS region that shares the enqueue. The resource name is allowed to be up to 255 bytes but GRS limits it to 44 bytes so don't use more than 44 bytes in your ENQMODEL definition. ENQSCOPE is again any arbitrary 4-byte value; if it is not spaces then CICS passes GRS the name DFHE???? (where ???? is your 4-byte ENQSCOPE) and the resource name defined by ENQNAME in the ENQMODEL definition.
The ONLY way to achieve this is through RLS (record level sharing); in general an ENQ will be serialized at the cluster level.
Why are you not talking to your site support group? Very few, if any, sites allow an application programmer to use the CEDA transaction to define resources. CEDA is generally done by the site support group, so your asking all sorts of questions about it on a forum won't really help you that much.
