The present invention discloses methods and systems for hosting tenants over a network in a computer-based environment in which a provider may store a shared data structure having shared data. A tenant receives a request for a shared data structure and retrieves the shared data structure from the provider based on shared metadata identifying the locations of shared data structures stored at the provider. In addition, based on extension metadata, the tenant retrieves an extended data structure including tenant-specific elements unique to the first tenant. The tenant server then combines the shared and extended data structures into a combined data structure including the tenant-specific elements.

Systems and methods to implement extensibility of tenant content in a provider-tenant environment

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 in a computer-based environment in which a provider stores a shared data structure. Each of the tenants may store shared-metadata referencing the shared data structure, while a first tenant may store a tenant-specific data structure specific to the first tenant for access by the first tenant. Based on the shared-metadata and in response to a data request from the first tenant, the system may the query the provider or the first tenant for requested data and provide the requested data based on the querying.

Systems and methods for implementing a tenant space in a provider-tenant environment

Exemplary methods and systems may associate data structures specific to a first tenant with a first tenant template, determine whether new data structures are specific to the first tenant, and if so, associate the new data structures with a second tenant template. By doing so, methods and systems may determine a difference between the first and second tenant templates, making it possible to upgrade a tenant based on the difference. With this capability a provider-tenant system may upgrade applications and data.

Software management systems and methods, including use of such systems and methods in a provider-tenant environment

The present invention discloses methods and systems for hosting tenants in a computer-based environment in which a provider stores a shared data structure. Each of the tenants may communicate with a middleware module storing metadata referencing the shared data structure and a tenant-specific data structure specific to the first tenant for access by the first tenant. Based on the metadata and in response to a data request from the first tenant, the system may the query the provider or the first tenant for requested data and provide the requested data based on the querying.

Systems and methods for accessing a shared space in a provider-tenant environment by using middleware

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.

Systems and methods for deploying a tenant in a provider-tenant environment

The present invention discloses methods and systems for tenants to execute application software hosted by a provider in a computer-based environment in which a provider may store a shared data structure associated with the application software, such that each of the plurality of tenants has access to the shared data structure. The provider may also distribute, to each of the plurality of tenants, respective tenant-specific data structures for storing data unique to each respective tenant for storage at each respective tenant, and send, based upon a data request generated by the application software, data of the shared data structure a first tenant of the plurality of tenants.

Systems and methods for accessing a shared space in a provider-tenant environment

Exemplary methods and systems may designate a data structure as tenant-specific or shared. By reviewing a plurality of data structures at the provider corresponding to a plurality of tenants, the provider may determine which of the plurality of data structures are specific to a first tenant of the plurality of tenants, and generate a tenant specific designation to identify a data structure as specific to the first tenant. Further, the provider may associate a data structure determined to be specific to the first tenant with the generated tenant specific designation. With this capability a provider-tenant system may separately store each tenants data.

Systems and methods for generating tenant-specific properties for use in a provider-tenant environment

Managing a computer system having a plurality of blades by detecting the presence of a new blade in the computer system; installing an operating system on the new blade; configuring the operation system; and copying a service that is running on an earlier detected blade to the new blade. Further features are testing services and operating system on the new blade and cyclically shifting services through the blades.

Managing a computer system with blades

A method for restarting a process running on a first processor includes preparing a second processor, copying process context information to the second processor, starting a second process using the context information on the second processor, and terminating a first process running on the first processor. The second process performs an equivalent function to the first process.

Restarting processes in distributed applications on blade servers

A method for displaying regions of a matrix. The matrix has at least one column and one or more rows having one or more fields related to individual data records. The method comprises: displaying a starting region of the matrix, the starting region having one or more rows with each row having a field corresponding a data record; determining a field corresponding to the matrix position which the computer user indicates via a first user interface; obtaining a data record to which the determined field is related; identifying the rows of the matrix relating to the obtained data record; displaying, on detection of a user request via a second user interface to continue to display, a second region of the matrix which contains at least one identified row.

Interface-controlled display of a matrix document in regions

Systems and methods are provided for changing a data structure, which an application program in a computer system uses to access database systems. According to an exemplary method, an application program communicates with a first database system to store entries in a source table having a first data structure. The method further includes creating a destination table in the first database system, such that the destination table has a second data structure and recording the type of change for those entries in the source table, which are changed when the application program communicates with the source table. The method further includes copying the destination table into a second database system and copying the source table in the second database system. Moreover, the method may include converting the entries in the copy of the source table from the first data structure to the second data structure and adjusting the changed entries in the source table to the copy of the source table, wherein the changed entries are copied from the source table as changed entries to the copy of the source table.
