Abstract
Method, system and article of manufacture for scheduling queries. In particular, the scheduling options made available to a user for a particular unit of work are determined dynamically at the time of scheduling. In this way, the execution cost, for example, of a particular unit of work can be taken into account when determining which scheduling options to make available. In addition, or alternatively, system availability and/or user parameters may be accounted for when determining which scheduling options to make available.
Claims14
A non-transitory computer readable storage medium containing a program which, when executed, performs an operation for scheduling execution of units of work, the operation comprising:
- determining a first cost to execute a first unit of work;
- determining a first set of user-selectable scheduling options for future execution of the first unit of work based on the first cost, wherein the first set of user-selectable scheduling options is a subset of a larger set of scheduling options, and wherein the larger set of scheduling options are stored on a computer readable storage medium and include a plurality of user-selectable time criteria and frequency criteria, wherein the time criteria specifies when the execution of a given unit of work will begin and the frequency criteria specifies how frequently the given unit of work will be executed;
- returning the first set of user-selectable scheduling options to a user interface for display, whereby the user interface presents:
- time criteria selection elements from which a user specifies a time at which execution of the first unit of work will begin;
- and
- frequency criteria selection elements from which the user specifies a frequency at which the first unit of work will be executed beginning at the specified time;
- determining a second cost to execute a second unit of work;
- determining a second set of user-selectable scheduling options for future execution of the second unit of work based on the second cost, wherein the second set of user-selectable scheduling options a subset of the larger set of scheduling options, and wherein the second set of user-selectable scheduling options is different than the first set of user-selectable scheduling options;
- and
- returning the second set of user-selectable scheduling options to a user interface for display, whereby the user interface presents:
- time criteria selection elements from which a user specifies a time at which execution of the second unit of work will begin;
- and
- frequency criteria selection elements from which the user specifies a frequency at which the second unit of work will be executed beginning at the specified time.

A computer system, comprising:
- a schedule indicating when units of work are to be executed;
- a scheduler configured to:
- determine a first cost to execute a first unit of work;
- determine a first set of user-selectable scheduling options for repetitive execution of the first unit of work on the basis of the first cost, wherein the scheduler determines the first set of user-selectable scheduling options base on the first cost, wherein the first set of user-selectable scheduling options is a subset of a larger set of scheduling options, and wherein the larger set of scheduling options are stored on a non-transitory computer readable storage medium and include a plurality of user-selectable time criteria and frequency criteria, wherein the time criteria specifies when the execution of a given unit of work will begin and the frequency criteria specifies how frequently the given unit of work will be executed;
- return the first set of user-selectable scheduling unit of work to the user interface for display, whereby the user interface presents:
- time criteria selection elements from which a user specifies a time at which execution of the first unit of work will begin;
- and
- frequency criteria selection elements from which the user specifies a frequency at which the first unit of work will be executed beginning at the specified time;
- determine a second cost to execute a second unit of work;
- determine a second set of user-selectable scheduling options for repetitive execution of the second unit of work on the basis of the second cost, wherein the scheduler determines the second set of user-selectable scheduling options based on the second cost, wherein the second set of user-selectable scheduling options is a subset of the larger set of scheduling options, and wherein the second set of user-selectable scheduling options is different than the first set of user-selectable scheduling options;
- and
- return the second set of user-selectable scheduling unit of work to the user interface for display, whereby the user interface presents:
- time criteria selection elements from which a user specifies a time at which execution of the second unit of work will begin;
- and
- frequency criteria selection elements from which the user specifies a frequency at which the second unit of work will be executed beginning at the specified time.
