Described herein are systems and methods for implementing a distributed ledger a blockchain cloud service. The blockchain cloud service can include nodes of the distributed ledger and a REST proxy service component. The REST proxy service uses a service development kit for the distributed ledger to communicate with the distributed ledger, and can provide REST APIs for use by client applications to query through chaincodes, synchronously or asynchronously invoke transactions through the chaincodes, get transaction statuses, and get BCS proxy versions. The REST proxy service component can authenticate REST calls, and translate the REST calls into remote procedural calls, for use in interfacing with the distributed ledger. The REST proxy service component can further provide REST APIs that support the same functions which are provided by the BCS management console component, and provide a user interface for client applications to consume the BCS instance.

System and method for providing a representational state transfer proxy service for a blockchain cloud service

In accordance with an embodiment, described herein is a system and method for implementing a distributed ledger a blockchain cloud service. The blockchain cloud service can include nodes of the distributed ledger and a management console component. The management console component can include a web application running in a script runtime environment, a plurality of backend of APIs for communicating with various nodes of the blockchain cloud service, and a plurality of client APIs configured to be invoked by a client application. The plurality of client APIs uses one or more of the plurality of backend APIs in provisioning the distributed ledger as a blockchain cloud service, and in managing the managing the blockchain cloud service.

In accordance with an embodiment, described herein is a system and method for conditional call path monitoring in a distributed transactional middleware environment. A cache can be provided in local memory, for use by an agent in the reporting and aggregation of call path metrics. When the agent collects such metrics, it does not report them immediately to a system and application monitor (SAM) manager (e.g., Tuxedo System and Application Monitor, TSAM), but instead stores them in the cache, indexed by correlation ID (identifier). When a predefined condition is met at a participating node, that node propagates a corresponding correlation ID to other participating nodes, via the SAM manager. The other participating nodes can then search for the correlation ID in the cache, and report to the SAM manager metrics of call paths which meet the condition.

Systems and methods for implementing a distributed ledger as a blockchain cloud service are provided. The blockchain cloud service can include nodes of the distributed ledger and a REST proxy service component. The REST proxy service uses a service development kit for the distributed ledger to communicate with the distributed ledger, and can provide REST APIs for use by client applications to query through chaincodes, synchronously or asynchronously invoke transactions through the chaincodes, get transaction statuses, and get BCS proxy versions. The REST proxy service component can authenticate REST calls, and translate the REST calls into remote procedural calls, for use in interfacing with the distributed ledger. The REST proxy service component can further provide REST APIs that support the same functions which are provided by the BCS management console component, and provide a user interface for client applications to consume the BCS instance.

A system and method can support batch job management in a distributed system using a queue system with a plurality of queues and one or more job management servers. The queue system can represent a life cycle for executing a job by a job execution component, with each queue in the queue system adapted to receive one or more messages that represent a job status in the life cycle for executing the job. The one or more job management servers in the distributed system can direct the job execution component to execute the job, with each job management server monitoring one or more queues in the queue system, and performing at least one operation on the one or more messages in the queue system corresponding to a change of a job status for executing the job.
