Abstract

The invention concerns a method for effecting a software service in at least one of a plurality of logical systems of a software system landscape, wherein the logical systems are interconnected by logical transport paths, each logical system has associated therewith one of a plurality of system roles and the software service relates to at least one of the code and the data of the at least one system, is described. The method includes providing a transport track that defines a route for software services through logical systems in a particular order and specifies one source system, adjacent interconnected systems, and at least one target system; generating a task list in a central task system from the transport track and the system roles, the task list defining tasks for routing a software service from a starting system to the at least one system and for implementing the preliminary software service in the at least one system; and scheduling in a central control system the execution of the tasks stored in the central task system and monitoring task statuses from the central control system.

Claims

1. A method for effecting a software service in at least one of a plurality of logical systems of a software system landscape, wherein the logical systems are interconnected by logical transport paths, each logical system has associated therewith one of a plurality of system roles and the software service relates to at least one of the code and the data of the at least one system, the method including:

providing a transport track that defines a route for software services through logical systems in a particular order and specifies one source system, adjacent interconnected systems, and at least one target system;

generating a task list in a central task system from the transport track and the system roles, the task list defining tasks for routing a software service from a starting system to the at least one system and for implementing the preliminary software service in the at least one system; and

scheduling in a central control system the execution of the tasks stored in the central task system and monitoring task statuses from the central control system.

2. The method of claim 1, wherein the scheduling comprises generating a schedule using predefined schedules for tasks and software service types.

3. The method of claim 1, wherein generating the task list comprises determining from the transport track which systems are affected, determining the system role type of each affected system, determining the software service type, and using predefined tasks associated to system role types and software service types.

4. The method of claim 3, wherein a preliminary software service type and a regular software service type are used as the software service types.

5. The method of claim 1, wherein the task list is generated with hierarchy levels.

6. The method of claim 5, wherein the hierarchy levels are generated to include a transport track level, a system role type level below the transport track level, a system role level below the system role type level, a system level below the system role level and a task level below the system level.

7. The method of claim 1, wherein as a system role type one of the group of source system, follow-on system or target system is used.

15. A computer program product comprising on a storage medium a computer code that upon execution on a computer system performs the method according to claim 1.

8. A computer system comprising:

a software system landscape comprising a plurality of logical systems that are interconnected by logical transport paths and each have associated therewith one of a plurality of system roles;

a transport track that defines a route for software services through logical systems in a particular order and specifies one source system, adjacent interconnected systems, and at least one target system, a software service relating to at least one of the code and the data of at least one system;

a central task system;

means for generating a task list in the central task system from the transport track and the system roles, the task list defining tasks for routing a software service from a starting system to the at least one system and for implementing the preliminary software service in the at least one system;

a central control system; and

means for scheduling in the central control system the execution of the tasks stored in the central task system and for monitoring task statuses from the central control system.

9. The system of claim 8, wherein predefined schedules for tasks and software service types are provided for use by the scheduling means.

10. The system of claim 8, wherein the means for generating are designed to determine from the transport track which systems are affected, to determine the system role type of each affected system, to determine the software service type, and to use predefined tasks associated to system role types and software service types.

11. The system of claim 10, wherein a preliminary software service type and a regular software service type are provided.

12. The system of one of claim 8, wherein the task list comprises hierarchy levels.

13. The system of claim 12, wherein the hierarchy levels include a transport track level, a system role type level below the transport track level, a system role level below the system role type level, a system level below the system role level and a task level below the system level.

14. The system of claim 8, wherein the system role type comprises one of the group of source system, follow-on system or target system.

16. A computer system comprising:

a software system landscape comprising a plurality of logical systems that are interconnected by logical transport paths and each have associated therewith one of a plurality of system roles;

a transport track that defines a route for software services through logical systems in a particular order and specifies one source system, adjacent interconnected systems, and at least one target system, a software service relating to at least one of the code and the data of at least one system;

a central task system;

a module to generate a task list in the central task system from the transport track and the system roles, the task list defining tasks for routing a software service from a starting system to the at least one system and to implement the preliminary software service in the at least one system;

a central control system; and

a module to schedule in the central control system the execution of the tasks stored in the central task system and to module task statuses from the central control system.
