A method includes defining, by a computing device, a network of nodes of migration practitioners; receiving, by the computing device, working sets from the nodes defining ownership of data servers; determining, by the computing device, a consensus of ownership of the data servers amongst the migration practitioners; updating, by the computing device, the working sets using the consensus of ownership; distributing, by the computing device, the updated working sets across the nodes; obtaining, by the computing device, activity wrappers of migration activities on the data servers within the distributed working sets; generating, by the computing device, migration activities based on the obtained activity wrappers; determining, by the computing device, connectivity problems in the network; resolving, by the computing device, the connectivity problems in the network; allowing, by the computing device, a new node to join the network; and assigning, by the computing device, ownership of unowned data servers.

An example operation may include one or more of receiving a database storage request at a decentralized database, executing an operation of the database storage request at a database node based on chaincode to generate a simulated result without committing the database storage request to the decentralized database, determining whether the chaincode of the database node is valid via a functional testing that is performed based on an output of the execution of the database storage request, and, in response to determining the chaincode is valid, endorsing the database storage request for storage at the decentralized database and transmitting the endorsement to one or more database nodes of the decentralized database.

Database node functional testing

A process for determining a problematic condition while running software includes: loading a first pattern data set into a volatile memory of a computer, with the first pattern data set being associated with a set of problematic conditions, determining that a runtime symptom code generated while running software on the computer matches a pre-defined symptom code in a set of pre-defined symptom codes, collecting information during runtime according to a set of data collection instructions as a set of collected data, and determining, by applying a set of logic data to the set of collected data, a first problematic condition of the set of problematic conditions triggered the runtime symptom code.

Pattern oriented data collection and analysis

At least one application in a distributed computing environment is deployed. At least one resource of a virtual machine is provided to the at least one application in the distributed computing environment. The at least one resource of the virtual machine provided is recorded in metadata and the at least one application receives the metadata and using the metadata the at least one application determines how much of the at least one resource of the virtual machine to utilize. A change to the at least one resource of the virtual machine is determined. Responsive to determining the change to the at least one resource of the virtual machine, the metadata is modified. The at least one application uses the modified metadata to determine how much of the changed at least one resource of the virtual machine to use.

Automated exploitation of virtual machine resource modifications

In a system for providing data and/or computational services, various resources are assigned a sort of points (called vouchers or IOUs) for work manager threads that are currently queued at each resource. When a resource (and its associated resource manager) has a relatively small queue, whereby the resource is holding a relatively small number of points, that resource will be assigned work manager threads for incoming services requests at a high preference, or priority. In this way, faster performing resources can more reliably be supplied with new requests, while relatively slow performing resources will tend not to unduly tie up limited work manager threads in long queues at the slow resources.

An apparatus, method, and system for receiving a request for a transaction using a computer system. An absence of a first identification of an application on a first user device is determined, when a beacon of the computer system does not detect the first identification within a defined geographical area. A plurality of transaction data from a transaction device is received. A second identification based on the received transaction data is generated. An installation status of the application on the first user device based on the generated second identification and the absence of the first identification is also generated.

Tracking an application installation state

A process for determining a problematic condition while running software includes: loading a first pattern data set having a symptom code module, a problematic condition determination module, and a set of responsive action module(s), generating a runtime symptom code in response to a first problematic condition being caused by the running of the software on the computer, determining that the runtime symptom code matches a symptom code corresponding to the first pattern data set, determining that the first problematic condition caused the generation of the runtime symptom code, and taking a responsive action from a set of responsive action(s) that corresponds to the first problematic condition.

A method for providing other than a 1:1 resource mapping may include receiving an indication of a selected resource reference element, receiving an indication of at least one resource to be associated with the resource reference element, and generating, via processing circuitry, a registry including a declarative policy defining an association of the selected resource reference element and the at least one resource in which the registry defines an other than 1:1 mapping between resource reference elements and resources.
