Abstract
Abstract Described is a server probe for use in a distributed data processing system having plural application server computer systems interconnected via a network wherein each application server has a database application including a plurality of executable data management tasks and an initialisation table storing a task configuration indicative of which ones of the tasks should be active. The server probe reads the task configuration from the initialisation table from a target one of the application servers, identifies the tasks which are active in the target one of the application servers, and generates an event message if active tasks identified differ from the tasks specified in the initialisation table.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
Server probe apparatus for a distributed data processing system having plural application server computer systems interconnected via a network, each application server having a database application including a plurality of executable data management tasks and an initialisation table storing a task configuration indicative of which ones of the tasks should be active, the apparatus comprising: means for reading the task configuration from the initialisation table from a target one of the application servers; means for identifying the tasks which are active in the target one of the application servers; and means for generating an event message if active tasks identified differ from the tasks specified in the initialisation table.
Claim 2
Dependent Claim
109 words
Server probe apparatus for a distributed data processing system having plural application server computer systems interconnected via a network, each application server having a database application including a plurality of executable data management tasks and an initialisation table storing a task configuration indicative of which ones of the tasks should be active, the apparatus comprising: means for reading the task configuration from the initialisation table from a target one of the application servers; means for identifying the tasks which are active in the target one of the application servers; and means for generating an event message if active tasks identified differ from the tasks specified in the initialisation table.
Claim 3
Dependent Claim
62 words
Apparatus as claimed in claim 1, wherein the generating means comprises restart means for making successive attempts to restart tasks which are specified in the initialisation table but inactive in the target one of the application servers and means for generating the event message after a predetermined plurality of failed attempts by the restart means to restart the or each inactive task.
Claim 4
Dependent Claim
17 words
Apparatus as claimed in claim 1, comprising an administration terminal having means for displaying the event messages.
Claim 5
Dependent Claim
111 words
A distributed data processing system having plural application server computer systems interconnected via a network, each application server having a database application including a plurality of executable data management tasks and an initialisation table storing a task configuration indicative of which ones of the tasks should be active, and server probe apparatus, said server probe apparatus comprising: means for reading the task configuration from the initialisation table from a target one of the application servers; means for identifying the tasks which are active in the target one of the application servers; and means for generating an event message if active tasks identified differ from the tasks specified in the initialisation table.
Claim 6
Dependent Claim
111 words
A distributed data processing system having plural application server computer systems interconnected via a network, each application server having a database application including a plurality of executable data management tasks and an initialisation table storing a task configuration indicative of which ones of the tasks should be active, and server probe apparatus, said server probe apparatus comprising: means for reading the task configuration from the initialisation table from a target one of the application servers; means for identifying the tasks which are active in the target one of the application servers; and means for generating an event message if active tasks identified differ from the tasks specified in the initialisation table.
Claim 7
Independent Claim
110 words
A method for managing data management tasks in a distributed data processing system having plural application server computer systems interconnected via a network, each application server having a database application including a plurality of executable data management tasks and an initialisation table storing a task configuration indicative of which ones of the tasks should be active, the method comprising the steps of: reading the task configuration from the initialisation table from a target one of the application servers; identifying the tasks which are active in the target one of the application servers; and generating an event message if active tasks identified differ from the tasks specified in the initialisation table.
Claim 8
Independent Claim
110 words
A method for managing data management tasks in a distributed data processing system having plural application server computer systems interconnected via a network, each application server having a database application including a plurality of executable data management tasks and an initialisation table storing a task configuration indicative of which ones of the tasks should be active, the method comprising the steps of: reading the task configuration from the initialisation table from a target one of the application servers; identifying the tasks which are active in the target one of the application servers; and generating an event message if active tasks identified differ from the tasks specified in the initialisation table.
Claim 9
Dependent Claim
54 words
A method as claimed in claim 5, wherein the generating step comprises: making successive attempts to restart tasks which are specified in the initialisation table but inactive in the target one of the application servers; and, generating the event message after a predetermined plurality of failed attempts to restart the or each inactive task.
Claim 10
Dependent Claim
16 words
A method as claimed in claim 5, comprising displaying the event message on a display device.
