Abstract

Generating a signaling service message for a message group of a sysplex coupled together using a signaling service includes executing, on a computer, a data transfer application that communicates with a respective partner data transfer application on each member of the message group, the data transfer application comprised of a plurality of interworking modules including an interface module. Generating the message also includes receiving by the interface module a request from one of the other interworking modules that is related to sending the signaling service message; and based on the request, determining by the interface module a type of message for the signaling service message. Based on the type of message, the interface module identifies a corresponding routine of an operating system executing on the computer which will generate the signaling service message; and invoking the corresponding routine which causes the operating system to generate the signaling service message.

Claims

1. A method for generating a signaling service message for a message group of a sysplex coupled together using a signaling service, the method comprising:

executing, on a computer, a data transfer application that communicates directly with a respective partner data transfer application on each member of the message group, the data transfer application comprised of a plurality of interworking modules including an interface module;

receiving by the interface module, on the computer, a request related to sending the signaling service message;

the request being received from one of the other interworking modules;

based on the request, determining by the interface module, on the computer, a type of message for the signaling service message;

based on the type of message, identifying, by the interface module, on the computer, a corresponding routine of an operating system executing on the computer which will generate the signaling service message; and

invoking the corresponding routine that causes the operating system to generate the signaling service message;

constructing, by the interface module, on the computer, contents to be included in the signaling service message;

wherein the interface module comprises a first control block data structure local to the computer;

wherein the signaling service message comprises the first control block data structure.

2. The method of claim 1, wherein the operating system comprises a cross-system coupling facility.

3. The method of claim 1, wherein the contents relate to a command to perform.

4. The method of claim 1, wherein the signaling service message relates to one of:

leaving the message group; and

joining the message group.

5. The method of claim 1, wherein the signaling service message relates to one of:

sending the signaling service message to one specific member of the message group; and

sending the signaling service message to all members of the message group.

6. The method of claim 1, wherein the signaling service message relates to replying to a previous signaling service message.

7. The method of claim 1, wherein the signaling service message relates to a QUERY signaling service message.

8. A system for generating a signaling service message for a message group of a sysplex coupled together using a signaling service, the system comprising:

a processor and a memory coupled to the processor, the memory configured to store program code executable by the processor;

the program code, when executed by the processor, configured to execute data transfer application that communicates directly with a respective partner data transfer application on each member of the message group, the data transfer application comprised of a plurality of interworking modules including an interface module;

the program code, when executed by the processor, configured to receive by the interface module, a request related to sending the signaling service message;

the request being received from one of the other interworking modules;

the program code, when executed by the processor, configured to, based on the request, determine by the interface module a type of message for the signaling service message;

the program code, when executed by the processor, configured to, based on the type of message, identify by the interface module a corresponding routine of an operating system executing on the system which will generate the signaling service message; and

the program code, when executed by the processor, configured to invoke the corresponding routine that causes the operating system to generate the signaling service message;

wherein the program code is further configured to construct, by the interface module, contents to be included in the signaling service message;

wherein the interface module comprises a first control block data structure local to the system;

wherein the signaling service message comprises the first control block data structure.

9. The system of claim 8, wherein the operating system comprises a cross-system coupling facility.

10. The system of claim 8, wherein the contents relate to a command to perform.

11. The system of claim 8, wherein the signaling service message relates to one of:

leaving the message group; and

joining the message group.

12. The system of claim 8, wherein the signaling service message relates to one of:

sending the signaling service message to one specific member of the message group; and

sending the signaling service message to all members of the message group.

13. The system of claim 8, wherein the signaling service message relates to replying to a previous signaling service message.

14. The system of claim 8, wherein the signaling service message relates to a QUERY signaling service message.

15. A computer program product for generating a signaling service message for a message group of a sysplex coupled together using a signaling service, the computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured to execute a data transfer application that communicates directly with a respective partner data transfer application on each member of the message group, the data transfer application comprised of a plurality of interworking modules including an interface module;
