Method And System For Transparently Accessing Non-Relational Hierarchical Databases Using Distributed Relational Database Architecture (DRDA) Protocol

Disclosed is a method and system for transparently accessing a collection of non-relational hierarchical databases across a sysplex (e.g., Parallel sysplex) using Distributed Relational Database Architecture (DRDA) protocol.

The following figure illustrates a system for transparently accessing the collection of non-relational hierarchical databases across the sysplex using the DRDA protocol.

non-relational hierarchical databases, their existence is made known via a sysplex-

notification system. The DRDA target server is registered with this sysplex-

notification system and is therefore dynamically aware of the existence of the non-relational hierarchical databases. These non-relational hierarchical databases may not be in the same database subsystem and may be unrelated to one another.

A single DRDA connection to the DRDA target server offers access to all the

non-relational hierarchical databases in the sysplex. Further, a sequence of DRDA protocol flows are utilized for connecting with the collection of non-relational hierarchical databases. The protocol flows are defined by a DRDA specification. However, typically
