Abstract
Provided are a method, system, and program for managing communication code changes between processors in which a local processor sends remote operation requests to be executed by a remote processor. In the illustrated embodiment, the local processor and the remote processor each have a control set for managing transfers of remote operation requests. The remote processor control set includes a queue for queuing remote operation requests awaiting execution. The control set of the local processor includes a credit counter which keeps track of permissible outstanding remote operation requests. The remote processor populates a configuration structure with information concerning the remote processor control set including the size of the queue and sends the configuration structure to the local processor. The local processor extracts the information from the configuration structure and configures the local processor control set. In the configuration, the credit counter is initialized in accordance with the capacity of the remote processor control set queue.
