Abstract

A system and method is provided for initiating batch processing on a computer system from a terminal. The method generates a message from the terminal, where the message defines a transaction to be performed on a computer system. The transaction schedules and runs a program that extracts data from the message. The message is then transmitted to the computer system. The data is then used to generate batch job control language and a batch job is run on the computer system. The output of the batch job is then routed back to the terminal.

Claims

1-30. -30. (canceled)

31. A method for initiating batch processing on a server from a client computer comprising:

generating a message from the client computer identifying a transaction to be initiated on the server;

transmitting the message to the server;

in response to processing the message at the server, extracting data from the message to use to generate a batch job control language (JCL);

running the batch JCL at the server to generate an output; and

routing the output of the batch JCL to the client computer.

32. The method of claim 31, wherein using the extracted data from the message to generate the batch JCL further comprises:

using character strings from the message to identify parameters to map in to the batch JCL.

33. The method of claim 32, wherein using the character strings further comprises:

mapping the parameters into JCL skeletons; and

determining which parts of the skeletons are to be retained and removed based on character string indicators to customize the JCL skeletons;

generating batch JCL streams from the customized JCL skeletons.

34. The method of claim 32, wherein using the extracted data from the message to generate the batch JCL further comprises:

using the character strings of the message to identify components to mapping into the batch JCL.

35. The method of claim 32, further comprising:

maintaining, by the server, predefined reserved keywords reperesenting character strings in the imessage which indicate an action to be taken or are associated with values supplied by the user.

36. The method of claim 35, wherein the reserved keywords include keywords used to specify a JCL skeleton number to use to generate the batch JCL.

37. The method of claim 35, wherein the reserved keywords include substitution variables that users can dynamically define in the message that are mapped into the JCL skeletons and substitution variable labels that identify labels at which substitution variables will be mapped into the JCL skeleton.

38. A system in communication with a client computer, comprising:

a processor; and

a computer readable storage device including programs executed by the processor to perform operations, the operations comprising;

receiving a message from the client computer identifying a transaction to be initiated on the server;

in response to processing the message, extracting data from the message to use to generate a batch job control language (JCL);

running the batch JCL at the server to generate an output; and

routing the output of the batch JCL to the client computer.

39. The system of claim 38, wherein using the extracted data from the message to generate the batch JCL further comprises:

using character strings from the message to identify parameters to map in to the batch JCL.

40. The system of claim 39, wherein using the character strings further comprises:

mapping the parameters into JCL skeletons; and

determining which parts of the skeletons are to be retained and removed based on character string indicators to customize the JCL skeletons;

generating batch JCL streams from the customized JCL skeletons.

41. The system of claim 39, wherein using the extracted data from the message to generate the batch JCL further comprises:

using the character strings of the message to identify components to mapping into the batch JCL.

42. The system of claim 39, wherein the operations further comprise:

maintaining, by the server, predefined reserved keywords reperesenting character strings in the imessage which indicate an action to be taken or are associated with values supplied by the user.

43. The system of claim 42, wherein the reserved keywords include keywords used to specify a JCL skeleton number to use to generate the batch JCL.

44. The system of claim 42, wherein the reserved keywords include substitution variables that users can dynamically define in the message that are mapped into the JCL skeletons and substitution variable labels that identify labels at which substitution variables will be mapped into the JCL skeleton.

45. A computer program product comprising a computer readable medium device having computer readable program code embodied therein that is executed by a processor to communicate with a client computer and to perform operations, the operations comprising:

receiving a message from the client computer identifying a transaction to be initiated on the server;

in response to processing the message at the server, extracting data from the message to use to generate a batch job control language (JCL);

running the batch JCL at the server to generate an output; and

routing the output of the batch JCL to the client computer.

46. The computer program product of claim 45, wherein using the extracted data from the message to generate the batch JCL further comprises:

using character strings from the message to identify parameters to map in to the batch JCL.

47. The computer program product of claim 46, wherein using the character strings further comprises:

mapping the parameters into JCL skeletons; and

determining which parts of the skeletons are to be retained and removed based on character string indicators to customize the JCL skeletons;

generating batch JCL streams from the customized JCL skeletons.

48. The computer program product of claim 46, wherein using the extracted data from the message to generate the batch JCL further comprises:

using the character strings of the message to identify components to mapping into the batch JCL.

49. The computer program product of claim 46, further comprising:

maintaining, by the server, predefined reserved keywords reperesenting character strings in the imessage which indicate an action to be taken or are associated with values supplied by the user.

50. The computer program product of claim 49, wherein the reserved keywords include keywords used to specify a JCL skeleton number to use to generate the batch JCL.

51. The computer program product of claim 49, wherein the reserved keywords include substitution variables that users can dynamically define in the message that are mapped into the JCL skeletons and substitution variable labels that identify labels at which substitution variables will be mapped into the JCL skeleton.
