Method and apparatus for resource dependency relaxation

An apparatus that implements a policy for resource failure in a computer network, comprising:

• means for receiving a failure event corresponding to a failure of a first network resource;
• means for determining a second network resource that has a dependency relationship with the first network resource;
• means for, if the dependency relationship between the first and the second network resource is a relaxed dependency relationship, performing actions determined by a plurality of relaxation rules for the first and second network resources;
• and
• means for performing actions determined by a plurality of event handler rules for the failure event.

An apparatus that implements a policy for resource failure in a computer network, comprising:

• a portion configured to receive a failure event corresponding to a failure of a first network resource;
• a portion configured to determine a second network resource that has a dependency relationship with the first network resource;
• a portion configured, if the dependency relationship between the first and the second network resource is a relaxed dependency relationship, to perform actions determined by a plurality of relaxation rules for the first and second network resources;
• and
• a portion configured to perform actions determined by a plurality of event handler rules for the failure event.

A computer program product, comprising:

• a computer usable medium having computer readable code embodied thereon for causing implementation of a policy dealing with resource failure in a computer network, the computer program product including:
• computer readable program code devices configured to cause a computer to effect receiving a failure event corresponding to a failure of a first network resource;
• computer readable program code devices configured to cause a computer to effect determining a second network resource that has a dependency relationship with the first network resource;
• computer readable program code devices configured to cause a computer to effect, if the dependency relationship between the first and the second network resource is a relaxed dependency relationship, performing actions determined by a plurality of relaxation rules for the first and second network resources;
• and
• computer readable program code devices configured to cause a computer to effect performing actions determined by a plurality of event handler rules for the failure event.

A computer data signal embodied in a carrier wave and representing sequences of instructions which, when executed by a processor, cause implementation of a policy dealing with resource failure in a computer network, by performing the steps of:

• executing a computer program to receive a failure event corresponding to a failure of a first network resource;
• executing a computer program to determine a second network resource that has a dependency relationship with the first network resource;
• executing a computer program, if the dependency relationship between the first and the second network resource is a relaxed dependency relationship, to perform actions determined by a plurality of relaxation rules for the first and second network resources;
• and
• executing a computer program to perform actions determined by a plurality of event handler rules for the failure event.
