In one aspect, a universal storage manager in a multi-tenant computing system receives at least one message requesting a change to a storage infrastructure of the multi-tenant computing system. Thereafter, the universal storage manager associates the requested change with one of a plurality of operations changing the storage infrastructure. Once this association is made, the universal storage manager initiates the associated operation to change the storage infrastructure. Related apparatus, systems, techniques and articles are also described.

Universal storage manager for modifying storage infrastructure in multi-tenant computing system

Described herein are systems and methods for three phase exception handling ensuring high availability of services. Via unified application program interface (API), one or more inspector instances are observing the behavior one or more services. The three phase exception handling is triggered upon observing an abnormal service behavior. Phase one comprises executing one or more commands from the unified API by the one or more inspector instances in attempt to resolve the abnormal service behavior and notifying a centralized inspector engine. Phase two comprises executing one or more predefined rules according to the current service state by the centralized inspector engine in attempt to resolve the abnormal service behavior and notifying an administrator. Phase three comprises abnormal service behavior analysis by the administrator and executing customized by the administrator rules to resolve the abnormal service behavior.

Ensuring high availability of services via three phase exception handling

A method includes generating at a client, operating on a user computer, a URL request having URL parameters according to a representational state transfer (REST) protocol, transmitting the URL request from the client to a gateway, which is operating on a server computer, and extracting via the gateway the URL parameters according to the REST protocol. The method further includes generating via the gateway a query for hosted content identified by the URL parameters, transmitting the query to the database, generating a search report for the query, and transmitting the search report from the database to the gateway. The method further includes encoding via the gateway the search report in an XML representation according to the REST protocol, and transmitting the search report in the XML representation from the gateway to the client where the client decodes the search report in the XML representation via the REST protocol for display.

Computer method for in-memory (CO-PA) clients and corresponding computer system

Exemplary methods and systems may clone a tenant database and send updates to the clone. By doing so, methods and systems may determine a difference between the clone and the tenant, making it possible to test upgrades for a tenant based on the difference. With this capability, a provider-tenant system may upgrade tenant business applications and customize tenant databases.

Method and system for cloning a tenant database in a multi-tenant system

The present invention discloses methods and systems for hosting tenants over a network in a computer-based environment in which a provider may receive data structures corresponding to a first tenant, determine which of the data structures are specific to the first tenant and which the data structures are shared with the other tenant; generate a tenant template that stores the data structures specific to the first tenant, and use the tenant template to generate a tenant database corresponding to the first tenant and storing the data structures specific to the first tenant.
