1. A method of backing out executable code components in a computing environment, said method comprising:
- determining an executable code component of said computing environment to be backed out from one version to a version different from said one version, wherein said executable code component is capable of emulating another version being executed by at least one other executable code component of said computing environment, and wherein said executable code component and said at least one other executable code component are associated with at least a portion of a unit of work; and
backing said executable code component out from said one version to said version different from said one version.

Abstract
A backing out capability backs out a component of a computing environment, while maintaining the availability of the computing environment. In particular, a component of the computing environment which is associated with at least a portion of a unit of work is backed out from one version to another version. In addition, the backed out component is capable of emulating the other version.
