Technology for monitoring all resources and services of a distributed computing environment to collect and store information technology (IT) infrastructure resources, task resource usage metrics, and idle times of the environment. A system management task, both manually created by administrators and automatically scheduled, is queued on a management queue to be processed at a later time. When the system management task is removed from the queue, resources required to execute the activity of the distributed computing environment are then requested. The task is authorized to execute if the requested resources and time to complete the activity are available. The resources are then secured and the system management task executed in the distributed computing environment.

System management and maintenance in a distributed computing environment

A solution is proposed for populating a policy file in a Java environment automatically. For this purpose, there is provided a wrapper for a security manager in charge of controlling any access to protected resources. A generic Java application is run in a test environment. Whenever a specific operation must be executed on a secured resource, the Java application submits a corresponding permission request to the wrapper. The wrapper forwards the permission request to the security manager, which verifies whether the required permission is available in the policy file. The wrapper logs any denied permission. In any case, the wrapper always grants the required permission to the Java application, so that its operation can continue without any problem. At the end of the running of the Java application, the logged missing permissions are added to the policy file.
