Some embodiments are directed to an improved approach to implement deployments where a client can get application-level redirects to different servers, where the service is running in a different cloud environment. Dynamic port mapping may be performed at runtime. Routes may be added to IP tables to implement redirects from a first cloud to a second cloud.

Private link based access with port mapping for service deployed in a separate cloud

Techniques are provided for maintaining snapshots of state information for a plurality of resource entities, within a distributed cloud service. A first snapshot of state information for the plurality of resource entities is maintained at an endpoint in persistent storage. A request to modify resources allocated to resource entities is received. A virtual lock on the state information reflected in the first snapshot is obtained. Upon obtaining the virtual lock, a service determines, based on the first snapshot, that there are available resources to perform the request to modify resources. A second snapshot of the state information, reflecting the modification of resources allocated to resource entities, is then generated and stored at the endpoint in persistent storage. The virtual lock on the state information is released and the resources allocated to the resource entities are modified according to the request.

Representation and management of infrastructure state of a distributed database cloud service

Disclosed is an improved approach to implement a mechanism to provide customer control over access to cloud infrastructure by the cloud provider's operator employees. This mechanism allow customer controlled access to any cloud infrastructure that belongs to or is otherwise allocated to the customer.

Framework for customer control and auditing of operator access to infrastructure in a cloud service

Provided is a process for determining a number of parallel threads for a request. The process involves receiving availability data regarding processing resources, wherein the availability data indicates which processing resources are idle or are to become idle. Based on the availability data, a number of parallel threads for the request is determined.

System and method for dynamic determination of a number of parallel threads for a request

A method, a master database node and a subscriber database node for optimizing an index. The method for optimizing index includes: checking, by a master database node, if role information of an index matches role information of the master database node, when the index is added into the master database node; updating database information by using the index when the role information of the index matches the role information of the master database node. In this invention, unnecessary indexes in the master database node and the subscriber database node are reduced while keeping the schema the same. Furthermore, unnecessary logs transmitted from the master database node to the subscriber database node are reduced.

Method for optimizing index, master database node and subscriber database node

Method, device, and system for peer-to-peer data replication are provided. The method includes: generating a first commit redo record attached with a CSN when a first write operation happens on a first physical entity in a master node, wherein the master node is preset with the first physical entity and a second physical entity and is connected to a first subscriber node and a second subscriber node; pushing, the first commit redo record to a first subscriber node corresponding to the first physical entity based on mapping relationships between the physical entities and the subscriber nodes, wherein the first commit redo record is used for replicating data of the first write operation from the master node to the first subscriber node, and then to the second subscriber node through pushing, by the first subscriber node, the received first commit redo record to the second subscriber node.

Method, device, and system for peer-to-peer data replication and method, device, and system for master node switching

A method, a master database node and a subscriber database node for optimizing index. The method for optimizing index includes: checking, by a master database node, if role information of an index matches role information of the master database node, when the index is added into the master database node; updating database information by using the index when the role information of the index matches the role information of the master database node. In this invention, unnecessary indexes in the master database node and the subscriber database node are reduced while keeping the schema the same. Furthermore, unnecessary logs transmitted from the master database node to the subscriber database node are reduced.

A method and system for optimizing replication in a distributed network is described. The instant invention allows for determining existing cluster topology of the network by one or more router(s) device(s) operating in the network, identifying and optimizing a data replication stream/service in use in network, by said router(s); determining a routing scheme based on the cluster topology by the router routing data packets though said network based on said routing scheme and applying predefined policy to a predefined set of router(s) corresponding to identified data replication stream by the router.

Method and device for database and storage aware routers

A debugging method is proposed in the disclosure. A computer running a program generates a master core dump file and one or more slave core dump files in response to a triggering event such as an internal failure. The core dump files are analyzed by another computer for debugging the program. The master core dump file includes an index list, and each entry of the index list corresponds to a slave core dump file of the one or more slave core dump files. The master core dump file can be the first to be transferred to the other computer. Based on the information in the index list, the other computer selectively requests one or more slave core dump files from the generated slave core dump files for debugging.

Method for debugging a computer program

A method and an apparatus of maintaining data for online analytical processing in a database system. The method includes: tracking a changed page in a main process; and synchronizing the changed page to a child process for online analytical processing. In the method and apparatus of maintaining data for online analytical processing, the changed pages are tracked and then the child process is synchronized with the changed pages. Therefore, periodic forking is avoided, fork overhead due to periodic forking in the prior art is removed, the synchronization is faster since only the changed pages are synchronized, and the performance of online data processing is enhanced.
