Abstract

A mechanism minimizes the management issues of the participant objects of the logical target set, such as an application set. The mechanism maps the current physical implementation. The mechanism then identifies the target and extraneous object set locations to facilitate isolation. Thereafter, the mechanism optimizes the logical target set placement for best manageability and performance. The mechanism minimizes the management issues by providing a small application footprint. This is accomplished by placing the object set on the fewest necessary volumes to facilitate both application performance and independence of administrative action.

Claims

1. A data processing system comprising:

a bus system;

a communications system connected to the bus system;

a memory connected to the bus system, wherein the memory includes a set of instructions; and

a processing unit connected to the bus system, wherein the processing unit executes the set of instructions to identify an application set, wherein the application set comprises a grouping of application objects related to an application;

determine application objects unrelated to the application;

determine on which physical storage units the application objects reside;

obtain a growth rate for the application objects;

set free space requirements and projections based on the growth rate for the application objects;

determine a layout of the application objects based on the determined physical storage units where the application objects reside, wherein the layout increases manageability of the application, and wherein the determined layout of the application objects isolates application objects related to an application from application objects unrelated to the application;

determine a layout of tablespaces, containers, and volumes for the application set based on the free space requirements and projections to recommend an accommodation of the application set on a minimum number of volumes; and

create tasks to implement the determined layout of the application objects, wherein creating the tasks to implement the determined layout of the application objects includes unloading the application objects currently residing on the physical storage units, re-defining infrastructure of the physical storage units based on the determined layout of the application objects, creating new data description language tasks, and loading the application objects in the re-defined infrastructure using the data description language tasks.

2. The data processing system of claim 1, wherein the processing unit further executes the set of instructions to determine a current size of the application objects.

3. The data processing system of claim 1, wherein the processing unit further executes the set of instructions to map the infrastructure of the physical storage units.

4. The data processing system of claim 1, wherein the layout of tablespaces, containers, and volumes for the application set is based on usage and performance requirements.

5. A computer program product comprising:

a computer readable storage medium encoded with computer usable program code that is executable by a computer for resolving intermixed application objects in storage, the computer program product including;

computer usable program code for identifying an application set, wherein the application set comprises a grouping of application objects related to an application;

computer usable program code for determining application objects unrelated to the application;

computer usable program code for determining on which physical storage units the application objects reside;

computer usable program code for obtaining a growth rate for the application objects;

computer usable program code for setting free space requirements and projections based on the growth rate for the application objects;

computer usable program code for determining a layout of the application objects based on the determined physical storage units where the application objects reside, wherein the layout increases manageability of the application, and wherein the determined layout of the application objects isolates application objects related to an application from application objects unrelated to the application;

computer usable program code for determining a layout of tablespaces, containers, and volumes for the application set based on the free space requirements and projections to recommend an accommodation of the application set on a minimum number of volumes; and

computer usable program code for creating tasks to implement the determined layout of the application objects, wherein creating the tasks to implement the determined layout of the application objects includes unloading the application objects currently residing on the physical storage units, re-defining infrastructure of the physical storage units based on the determined layout of the application objects, creating new data description language tasks, and loading the application objects in the re-defined infrastructure using the data description language tasks.

6. The computer program product of claim 5, further including:

computer usable program code for determining a current size of the application objects.

7. The computer program product of claim 5, further including:

computer usable program code for mapping the infrastructure of the physical storage units.

8. The computer program product of claim 5, wherein the layout of tablespaces, containers, and volumes for the application set is based on usage and performance requirements.
