Restoring system functionality when primary maintenance interface is unavailable

1. A method for restoring system functionality when a primary maintenance interface is unavailable, the method comprising the computer-implemented processes of:

receiving an indication that the primary maintenance interface, which is a time sharing option (TSO) interface, for troubleshooting a mainframe system is unavailable, wherein the indication is based on monitoring the TSO interface;

in response to the indication that the TSO interface is unavailable, retrieving a computer maintenance application that is configured to use a Virtual Telecommunications Access Method (VTAM) interface to connect to a mainframe system, wherein the computer maintenance application is retrieved from a datastore;

accessing the mainframe system with the computer maintenance application using the VTAM interface, wherein the computer maintenance application performs the troubleshooting on the mainframe system via the VTAM interface in response to the TSO interface being unavailable for the troubleshooting; and

performing a maintenance activity on the mainframe system using the computer maintenance application.

2. The method of claim 1 , further comprising:

adapting a set of troubleshooting functions used to troubleshoot the mainframe system to function over the VTAM interface; and

including the set of troubleshooting functions in the computer maintenance application.

3. The method of claim 2 , wherein at least one troubleshooting function of the set of troubleshooting functions is a modified function based on a time sharing option (TSO) troubleshooting function.

4. The method of claim 1 , wherein the maintenance activity is selected from at least one of: accessing a user catalog, accessing a system dataset, restarting a system service, installing a driver, or scheduling a job.

5. The method of claim 1 , wherein the indication that the TSO interface is unavailable for the troubleshooting of the mainframe system is based on an unavailability of a Transmission Control Protocol/Internet Protocol (TCP/IP).

6. The method of claim 1 ,

wherein the mainframe system is a mainframe in a networked computing environment, and

wherein the TSO interface is unavailable because a service that supports the TSO is unavailable, the service being a Job Entry Subsystem 2 (JES2).

7. The method of claim 6 , wherein the networked computing environment is a cloud computing environment and wherein the mainframe executes a z/OS operating system.

8. A system for restoring system functionality when a primary maintenance interface is unavailable, comprising:

a memory medium comprising instructions;

a bus coupled to the memory medium; and

a processor coupled to the bus that when executing the instructions causes the system to:

receive an indication that the primary maintenance interface, which is a time sharing option (TSO) interface, for troubleshooting a mainframe system is unavailable, wherein the indication is based on monitoring the TSO interface;

in response to the indication that the TSO interface is unavailable, retrieve a computer maintenance application that is configured to use a Virtual Telecommunications Access Method (VTAM) interface to connect to a mainframe system, wherein the computer maintenance application is retrieved from a datastore;

access the mainframe system with the computer maintenance application using the VTAM interface, wherein the computer maintenance application performs the troubleshooting on the mainframe system via the VTAM interface in response to the TSO interface being unavailable for the troubleshooting; and

perform a maintenance activity on the mainframe system using the computer maintenance application.

9. The system of claim 8 , the instructions further causing the system to:

adapt a set of troubleshooting functions used to troubleshoot the mainframe system to function over the VTAM interface; and

include the set of troubleshooting functions in the computer maintenance application.

10. The system of claim 9 , wherein at least one troubleshooting function of the set of troubleshooting functions is a modified function based on a time sharing option (TSO) troubleshooting function.

11. The system of claim 8 , wherein the maintenance activity is selected from a at least one of: accessing a user catalog, accessing a system dataset; restarting a system service, installing a driver, or scheduling a job.

12. The system of claim 8 , wherein the indication that the TSO interface is unavailable for the troubleshooting of the mainframe system is based on an unavailability of a Transmission Control Protocol/Internet Protocol (TCP/IP).

13. The system of claim 1 ,

wherein the mainframe system is a mainframe in a networked computing environment, and

wherein the TSO interface is unavailable because a service that supports the TSO is unavailable, the service being selected a Job Entry Subsystem 2 (JES2).

14. The system of claim 13 , wherein the networked computing environment is a cloud computing environment and wherein the mainframe executes a Z/OS operating system.

15. A computer program product for restoring system functionality when a primary maintenance interface is unavailable, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause an electronic computation device to:

receive an indication that the primary maintenance interface, which is a time sharing option (TSO) interface, for troubleshooting a mainframe system is unavailable, wherein the indication is based on monitoring the TSO interface;

in response to the indication that the TSO interface is unavailable, retrieve a computer maintenance application that is configured to use a Virtual Telecommunications Access Method (VTAM) interface to connect to a mainframe system, wherein the computer maintenance application is retrieved from a datastore;

access the mainframe system with the computer maintenance application using the VTAM interface, wherein the computer maintenance application performs the troubleshooting on the mainframe system via the VTAM interface in response to the TSO interface being unavailable for the troubleshooting; and

perform a maintenance activity on the mainframe system using the computer maintenance application.

16. The computer program product of claim 15 , the computer program product further includes program instructions, that when executed by the processor, cause the electronic computation device to:

adapting a set of troubleshooting functions used to troubleshoot the mainframe system to function over the VTAM interface; and

including the set of troubleshooting functions in the computer maintenance application.

17. The computer program product of claim 16 , wherein at least one troubleshooting function of the set of troubleshooting functions is a modified function based on a time sharing option (TSO) troubleshooting function.

18. The computer program product of claim 15 , wherein the maintenance activity is selected from at least one of: accessing a user catalog, accessing a system dataset; restarting a system service, installing a driver, or scheduling a job.

19. The computer program product of claim 15 , wherein the indication that the TSO interface is unavailable for the troubleshooting of the mainframe system is based on an unavailability of a Transmission Control Protocol/Internet Protocol (TCP/IP).

20. The computer program product of claim 15 ,

wherein the mainframe system is a mainframe in a networked computing environment, and

wherein the TSO interface is unavailable because a service that supports the TSO is unavailable, the service being selected a Job Entry Subsystem 2 (JES2).
