Abstract: A method for singleton process control in a computer environment is provided. A process identification (PID) for a background process is stored in a first temporary file. A determination operation is performed for determining if the parent process is alive for a predetermined number of tries. The PID of the background process is written from the first temporary file into a first PID variable when the parent process ends. A determination operation is performed for determining whether a second, global temporary file is empty. The background process is exited if an active PID is determined to exist in a second, global temporary file. The PID from the first temporary file is stored into the second, global temporary file. A singleton code block is then executed.

Abstract: A method for singleton process control in a computer environment is provided. A process identification (PID) for a background process is stored in a first temporary file. The PID is stored by a parent process and subsequently accessed by the background process. The background process is exited if an active PID is determined to exist in a second, global temporary file. The PID from the first temporary file is stored into the second, global temporary file. A singleton code block is then executed.

Abstract: An approach to generating logical configuration commands for logical objects in a system. A method may involve receiving a command requesting the logical configuration commands to configure the specified logical object (subject logical object) and the logical objects that support the logical object (the support logical objects). The method may also involve determining what logical objects in the system support the subject logical object. This may require determining the support logical objects that directly support the subject logical object, and then recursively examining each support logical objects to find the logical objects on which they depend. For each logical object (whether the subject logical object or one of the support logical objects), the method may involve determining the logical configuration commands to appropriately create and modify the logical object. The logical configuration commands may then be presented to the user.

Abstract: A method, system, and computer program product for providing dynamic context assistance to a user of a system, such as a storage system. One or more current command line interface (CLI) entries that are entered in a CLI of the system are received and a current state of the system is determined. Dynamic context assistance is then generated for one or more current CLI entries based on entered values of the one or more CLI entries. In this regard, the dynamic context assistance can be generated and displayed in a text or graphical form when one or more dynamic context assist keys are entered in the CLI in conjunction with the current CLI entry.

Abstract: A method for concurrently converting a standard volume to a thin-provisioned volume includes initially establishing metadata for a thin-provisioned volume. The method then updates the metadata for the thin-provisioned volume to point to extents residing in a standard volume. The method then suspends I/O to metadata for the standard volume. Upon suspending the I/O, the method migrates control of the extents in the standard volume from a standard-volume control algorithm to a thin-provisioned-volume control algorithm. The method then resumes the I/O to the metadata for the thin-provisioned volume. Using this technique, standard volumes may be rapidly converted to thin-provisioned volumes while minimally disrupting I/O to the volumes. A corresponding apparatus and computer program product are also disclosed and claimed herein.

Abstract: A method for executing a software routine identified in a task object is provided. The method includes accessing a list of software routine identifiers associated with software routines that are executable on a computer server. The method further includes generating a task object generation command having at least a first software routine identifier, parameter data, and link task information and generating a second task object in response to the task object generation command. The second task object includes the first software routine identifier, the parameter data, and the link task information.

Abstract: A method for storing data includes establishing a space efficient storage system including a virtual repository, a staging repository and a remote repository. The virtual repository includes a first pointer to the staging repository, and the staging repository includes a second pointer to the remote repository. The method further includes receiving data at the virtual repository, storing the received data in the staging repository based on the first pointer, and transferring the stored data to the remote repository based on the second pointer.
