The paper addresses a problem in software operation that maintenance tasks may lead to software failures. A model for automated checking of software execution environment is proposed. The provided solution is to develop a “profile” for each deployable item which contains information about software requirements regarding its execution. The profile document is added to software deliverables together with a set of tools capable of validating the adequacy of the execution environment according to the document. Regular checks of execution environment may be performed during system operation. The paper discusses first practical results of the proposed approach.
