Methods, systems, and computer-readable storage media for authorizing execution of processes that access cached data of an application running in a virtualized cloud environment. A first composite encrypted value comprising a first encrypted secret and a first secure hash value of a first secret is retrieved at a first virtual machine. The first encrypted secret is decrypted using a cryptographic key to determine a second secret to be used for initiating a first process (pα) on the first virtual machine. A second secure hash value of the second secret is generated. The second secure hash value is compared with the first secure hash value to determine whether to authorize execution of the first process on the first virtual machine using the first secret. In response to determining that the second secure hash value and the first secure hash value match, the first process is initiated at the first virtual machine.

A method for smart mounting of a first storage device to a first server includes receiving, at a first peer-to-peer communication component of a first server, a request from a second peer-to-peer communication component of a second server, the request being a request to mount a first storage device to said first server. The request is a request to mount a first storage device to said first server. The request is using a peer-to-peer communication protocol between the first and the second peer-to-peer communication components without using a central instance between the first and the second server.

Documents are compressed. A partially compressed document is obtained. The partially compressed document includes one or more code words that replace one or more common tokens of a document to be compressed. The one or more common tokens are tokens common to a plurality of documents, and included in a common dictionary. The common dictionary provides a mapping of code words to common tokens. A document associated dictionary is created from non-common tokens of the document to be compressed. The document associated dictionary provides another mapping of other code words to the non-common tokens. A compressed document is created. The creating of the compressed document includes replacing one or more non-common tokens of the partially compressed document with one or more other code words of the document associated dictionary. The compressed document includes the one or more code words of the partially compressed document and the one or more other code words of the document associated dictionary.

Compressing a plurality of documents

Methods, systems, and computer-readable storage media for receiving, by an operation controller, a call to trigger an operation, the call at least partially including an identifier associated with an operation signature, providing the operation signature based on the identifier, identifying, by the operation controller, an operation provider that provides the operation corresponding to the operation signature, validating, by the operation provider, one or more conditions for execution of the operation, and executing the operation to affect an entity within a landscape in response to the one or more conditions being valid.

Model-based service registry for software systems

Methods, systems, and computer-readable storage media for executing service calls, and include receiving a service call including a flat structure of a set of key-value pairs, providing a blueprint including one or more blueprint expressions, for at least one blueprint expression included in the blueprint, determining a specific value by processing at least one blueprint expression of the blueprint using a value of a key-value pair, and providing the specific value for execution of the process.

Service blueprint creation for complex service calls

In an approach for calculating a probability of a consistency violation of a transaction in a database management system, a processor receives a plurality of transactions within a predetermined time period. A processor identifies a first pattern in a first transaction of the plurality of transactions based on at least an isolation level of the transaction. A processor identifies a second pattern, wherein the second pattern is the cooperation between the first transaction and the second transaction. A processor determines that the first pattern of the first transaction substantially matches a preexisting pattern, wherein the preexisting pattern corresponds to values for a mathematical model for estimating a percentage of transactions in violation of consistency criteria. A processor extracts values from the first transaction based on the determined preexisting pattern. A processor calculates the mathematical model using the values from the first transaction and the values from the preexisting pattern.

A method for smart mounting of a storage device to a server may be provided. The method comprises providing a first peer-to-peer communication component to a first server a first storage device is controlled by, and providing a second peer-to-peer communication component to a second server a second storage device is controlled by. The method also comprises requesting, by said second server, a mounting of said first storage device of said first server using a direct communication between said first peer-to-peer communication component, and said second peer-to-peer communication component using a peer-to-peer communication protocol between said first and said second peer-to-peer communication component without using a central instance between said first and said second server, and providing mounting information of said first storage device to said second peer-to-peer communication component without using said central instance.

A method includes associating a state identifier with a page of a user interface; associating an element identifier with an element of the page of the user interface; and tracking a state of the element based on the state identifier and the element identifier throughout a user session of the user interface.

Web-browser based state repository

In an approach for optimizing read/write access to a document object model in a web browser, one or more computer processors detect one or more accesses to a first data structure of a document object model. Based on the detected one or more accesses, the one or more computer processors determine whether the first data structure is a highly dynamic part of the document object model. Responsive to determining the first data structure is a highly dynamic part of the document object model, the one or more computer processors trigger a conversion of the first data structure to an access optimized data structure. The one or more computer processors convert the first data structure to an access optimized data structure.
