Serialization of access to data in multi-mainframe computing environments

摘要

A multi-mainframe operating system serialization method can include receiving, in a first computing system, a request to access a data set on behalf of a first peer application, sending, in the first computing system, a notification to a second peer application to obtain a normal enqueue, in response to the second peer application obtaining the normal enqueue, obtaining, in the first computing system, a first rider enqueue for the data set and sending, in the first computing system, a communication to peer instances to obtain additional rider enqueues for the data set, the additional rider enqueues corresponding to the first rider enqueue.

1. A multi-computing system serialization method, comprising:
receiving, by a first computing system of the multi-computing system, a request to access a data set on behalf of a first peer application, wherein the first computing system does not support serialized access to the data set; sending, by the first computing system, a notification to a second peer application on a second computing system of the multi-computing system to obtain a normal enqueue, wherein the second computing system of the multi-computing system supports serialized access to the data set; in response to the second peer application obtaining the normal enqueue, obtaining, in the first computing system, a first rider enqueue for the data set; and sending, in the first computing system, a communication to peer instances to obtain additional rider enqueues for the data set, the additional rider enqueues corresponding to the first rider enqueue; in response to the first peer application completing access to the data set, releasing the rider enqueue and sending a notification to the second peer application to release the normal enqueue, wherein the first computing system is given serialized access to the data set via the second computing system in the multi-computing operation system.
