System programming considerations

This section discusses the CICS® resources that must be defined for asynchronous processing.

• A link to a remote system must be defined.
• Remote transactions that are to be initiated by start requests must be defined as remote resources to the local CICS system. This is not necessary, however, for transactions that are initiated only by START commands that name the remote system explicitly in the SYSID option.
• If the QUEUE option is used, the named queue must be defined on the system to which the start request is shipped. The queue can be either a local or a remote resource on that system.
• If a START request names a “reply” transaction, that transaction must be defined on the system to which the start request is shipped.
