摘要： Systems and methods to implement optimistic locking in online and offline environments are provided. A particular method includes receiving from an application an application data request related to retrieving a data item from a data store. The method also includes sending an optimistic locking information request to the data store to retrieve optimistic locking information, such as an identifier, associated with the data item. Additionally, the method includes receiving a data item update statement from the application while a connection between the application and a database server coupled to the data store persists or after a connection between the application and the database server has terminated and reconnected. The data item update statement relates to storing an updated version of the data item at the data store. Further, the method includes synchronizing the data item with the updated version of the data item based on the optimistic locking information.

摘要： Systems and methods to modify a set of connection records are described. A determination is made that an application failed to access a first database via a connection record, where the connection record includes data to access the first database. A determination is made that a second database is accessible, where the second database is a failover database to the first database. A set of connection records associated with the first database is modified to enable access to the second database.

摘要： According to one embodiment of the present invention, a system, method and computer program product or the administration of client side property settings in a distributed and heterogeneous environment is provided. According to one embodiment of the present invention, a method comprises establishing communication between a plurality of property agents and a property service, and looking up an identifier in a property repository for each property agent. A property setting in an updated client application associated with a selected one of the property agents is then modified by a database administrator. Changed property settings from the selected one of the property agents are then sent to the property service. Property settings associated with the updated client application are updated in the property repository. The updated property settings are sent from the property service to a plurality of property agents. The property agents may then merge the updated property settings into an associated application.

摘要： Provided are techniques for monitoring information. In response to a database process starting, a monitoring agent is loaded under control of the database process, wherein the monitoring agent invokes a discovery service to discover a central server and monitoring service. Under control of the monitoring agent, monitor information about the database process is sent to the central server and monitoring service.

摘要： An apparatus and method are disclosed for converting XML data to a destination encoding format. A receive module receives a request for bytes of XML data in a destination encoding format streamed from a source XML file. A transfer module transfers the requested bytes from a byte conversion buffer to a request buffer in response to the request and the byte conversion buffer having at least the requested bytes. A conversion module, in response to the byte conversion buffer lacking the requested quantity of bytes, transfers part of the requested bytes to the request buffer, fetches input bytes from an XML file, stores the bytes in a receive buffer, transfers the input bytes through a byte-to-character converter to a character conversion buffer, transfers the characters through a character-to-byte converter to the byte conversion buffer, and transfers enough bytes to the request buffer to satisfy the request.

摘要： Provided are techniques for, under control of an agent: receiving a request from a first database client to access a service from a set of services, wherein the agent is associated with the service; receiving a request from a second database client to access the service, wherein the agent is shared by the first database client and the second database client; combining information from the first database client and the second database client; and sending the combined information to the service using a single physical connection in a client-side Client Management Extension (CMX) connection, wherein the first database client and the second database client share the single physical connection.
