  • an escrow-locking multithreaded process-pair resource manager (PPRM) dictionary responsive to multiple concurrent transactions, the dictionary including;

    a dictionary resource;

    a concurrent aspect for concurrently servicing the multiple concurrent transactions, the concurrent aspect having an instance of the escrow-locking dictionary; and

    a serial aspect for serializing the multiple concurrent transactions, the serial aspect having an instance of the escrow-locking dictionary;

    wherein the escrow-locking dictionary allows multiple concurrent transactions of the concurrent aspect and serial transactions of the serial aspect to share the dictionary resource and to perform operations on behalf of the multiple concurrent transactions without compromising the atomic, consistent, isolated and durable (ACID) transaction properties.
