Abstract: A method and a system are provided for controlling deduplication in a storage pool. The method includes creating one or more deduplication domains within a storage pool, wherein storage volumes that are within a deduplication domain are deduplicated only with other volumes within the same deduplication domain and assigning storage volumes to a deduplication domain in order to control deduplication between storage volumes. The method may include, within a deduplication domain, blacklisting a volume from deduplication with a specified volume whilst allowing deduplication with other volumes in the deduplication domain.

Abstract: A computer-implemented method, apparatus, system and computer program product for optimizing parameter data passing between services in a service mesh, the method including receiving, at a first service, a request for the first service, the request including parameter data; storing the parameter data in a request parameter store, retrieving the parameter data from the request parameter store; the first service initiating a request for a second service, the parameter data in the request being replaced by a unique token identifying the parameter data in the request parameter store; and responsive to the second service using the parameter data, retrieving the parameter data from the request parameter store.

Abstract: A method, computer system, and computer program product for generating an optimized managed runtime application is provided. Method invocation statistics for a managed runtime application are received. The managed runtime application comprises code defining a plurality of classes, each class including bytecode for one or more methods associated with the class. The method invocation statistics identify the methods invoked during at least one previous execution of the managed runtime application. An optimized version of the managed runtime application is generated based on the method invocation statistics. The managed runtime application is retrieved, and bytecode for at least one method of a class of the managed runtime application is selectively replaced with proxy code based on the method invocation statistics. The proxy code is configured for retrieving the replaced code.

Abstract: A method and a system for permanently deleting data from storage. The method includes receiving a wipe command to permanently delete a data segment stored in a storage system. The data segment includes an address to blocks where the data of the data segment is stored. The method also includes sanitizing the data segment, marking the address as sanitized, locating a last journal entry in a journal. The last journal entry includes metadata regarding the data segment. The method also includes sanitizing the last journal entry, traversing the journal, and sanitizing each journal entry of the data segment.

Abstract: Method and system are provided for handling an underperforming drive in a redundant array of independent disks (RAID) operating a distributed sparing mechanism. The method includes marking an underperforming drive in the array as resting and allocating distributed spare space of the array for data of operations to the resting drive. A data structure is designated to track operations diverted to the distributed spare space from the resting drive. If the resting drive is recovered, the method rebuilds data to the recovered drive from the distributed spare space by reference to the data structure.

Abstract: A method of paged memory management for a software process executing in a memory of a computer system, the software process having a first operating mode and a second operating mode, and the software process having associated memory page use information for determining a set of pages to be maintained in the memory. The method comprises recording the memory page use information to a data store as first operating mode memory page use information in response to a determination that the software process leaves the first operating mode, and retrieving the first operating mode memory page use information in response to a determination that the software process enters the first operating mode.

Abstract: A method and system for code editing using copy and paste operations are provided. The method includes copying a section of text (111) from a source program text (101) and providing source context information (120) for the copied section of text (111). The method further includes pasting (140) the copied section of text (111) to a destination location, including: defining the pasted text (140) as separate from the destination program text (102); carrying out editing (132) to conform variables of the pasted text to the variables of the destination program text (102); and then integrating (133) the pasted text into the destination program text (102). The step of carrying out editing to conform variables of the pasted text (140) to the variables of the destination program text (102) references the source context information (120) and context information (104) of the destination program text (102).

Abstract: A code assistance feature provides a user with a set of suggested program code insertions at a given point in the program code being edited. For example, in response to a user command, the feature identifies syntactically correct possible insertions derived from a search for insertions of a compatible type. The feature identifies members in the set of possible code insertions that can be expanded via a field dereference or subroutine call to provide further possible code insertions for selection by the user.

Abstract: To facilitate code building, a user can identify an expression to be copied at a position in a source section of program code. Occurrences of the user-selected expression form a set of candidate code expressions. The user-selected expression may include some or all occurrences of a variable within an enclosing scope in the source section, program statements, etc. The formed set of candidate code expressions is presented to the user for user selection of one or more of the expression occurrences within the set. The set occurrences selected by the user are pasted to one or more target locations.

Abstract: A method, and system for employing the method, for virtual data storage migration providing a plurality of data storage devices communicating with at least one computer system. A plurality of data being managed by the computer system and an archive data storage device is selected from the plurality of data storage devices. Specified data is selected for archiving in the archive data storage device when the archive data meets a specified archive criteria. After the archived specified data is accessed in the archive data storage device at a predetermined frequency, the archive data is migrated to an active data storage device in a powered up state. The archive data storage device is then powering down.

Abstract: A method, apparatus and computer program element are disclosed for selecting a term for inclusion in a glossary in a document handling or processing system in which a set of functions or rules are applied to the term in order to provide a probability measure for the terms being suitable for inclusion in said glossary.

Abstract: A process and system for assisting a user to write new lines of code of a computer program based on code examples. A first line in each code sample matching a specified anchor line. A loop having a custom line branch and a code assist branch is executed. The custom line branch generates a new line for the computer program via a custom line provided by the user. The code assist branch generates a new line for the computer program via code assist. The code assist determines a set of assist lines from the code samples, translates the assist lines to a user context in each code example, selects from the assist lines set of preferred lines sequenced in an order of preference, presents the set of preferred lines to the user, receives a preferred line selected by the user, and stores the preferred line as a new line.
