Methods for using SQL statements to access an application-server-managed database are disclosed herein. In some embodiments, a user sends, either directly or indirectly (i.e., remotely) a SQL statement from an ODBC application or server, respectively, to an application server that preprocesses SQL statements for accessing data from a centralized database. The application server may have a SQL endpoint, and access to the SQL endpoint may be determined by a user's logon credentials, a user's presentation of a SAML token, or a user's presentation of a valid certificate. The application server may then parse the SQL statement and determine the user's authorization to access certain objects in the centralized database based on a SQL handler design-time configuration. A result from the statement may be sent back to the user either directly or indirectly and exposed.

Dedicated SQL services for cross-system SQL access to an application-server-managed database

The present disclosure involves systems, software, and computer implemented methods for event processing in background services. One example method includes receiving a request to create a daemon session, the request including at least one parameter. The session is created, including storing the at least one parameter in a memory storage that is configured to survive a restart of the session. A set of messages is received for the session. The messages are stored in a queue that is configured to survive a restart of the session. A determination is made that the session is to be restarted. A restart of the session is initiated, including providing the at least one parameter to the session during the restart of the daemon session and providing unprocessed messages to the session after the session has been restarted, to enable the session to process the unprocessed messages.

Event processing in background services

Disclosed herein are systems and methods for embedding database procedures in data-driven software applications written in a language different from the database-procedure language. For example, in some embodiments, the hosting application may be written in ABAP whereas the database procedure may be written in SQLScript. In various embodiments, the database procedures are encapsulated in specially marked methods of the host application, which, when called at runtime, cause the database procedures to be created in a database catalog and executed on a database server.

Embedding database procedures in data-driven applications

Disclosed herein are systems and methods facilitating extensions to software applications that access a database, and in particular to applications with embedded database procedures. In various embodiments, an extension anchor embedded in the application as well as one or more extensions implemented as database procedures are encapsulated in specially marked database-procedure methods.

Extensibility of embedded database procedures

Disclosed herein are systems and methods for the hot deployment of database procedures embedded in a host software application. In various example embodiments, the database procedures are encapsulated in specially marked methods of the host application, which, when called at runtime, cause the database procedures, and associated procedure stubs through which the database procedures are called, to be created in a database catalog and executed on the database server. When an embedded database procedure is modified in an application by one user during execution of that application by a second user, compilation of the modified database procedure may result in deletion of the original database procedure and/or associated procedure stub from the database, avoiding inconsistencies between database procedure versions during application execution by the second user.

Hot deployment of embedded database procedures

A system, a method and a computer-program product for exchanging communications between user sessions are provided. A first push channel and a first messaging channel on a first application server for connecting a first client to the first application server are established. The first messaging channel communicates with the first push channel, where both channels form a first session corresponding to the first client. A second push channel and a second messaging channel on a second application server for connecting a second client to the second application server are established. The second messaging channel communicates with the second push channel, where both channels form a second session corresponding to the second client. The first and second application servers communicate on a communication network. Messages are exchanged between the first and second messaging channels to form a connection between the first and second clients.

ABAP channels for event signaling

In one embodiment, a method includes defining a parent structure including an extension. A polymorphic structure is defined for the extension. The polymorphic structure is associated with a plurality of client specialization structures, each client specialization being associated with a client in a plurality of clients. During runtime by a computing device, the parent structure is generated with an extension to a client specialization structure associated with one of the plurality of clients where client specialization structures associated with other clients are not visible to the parent structure.

Generic boxed components for multi-client systems

Methods and apparatus, including computer program products, are provided for implementing a cooperative model between an application and a database. In one aspect, there is provided a computer-implemented method. The method may include receiving from an application a command to perform an operation at a database; accessing metadata representative of the application; configuring, based on at least the metadata, a result of the operation; and sending the configured result to shared memory accessible by the application. Related apparatus, systems, methods, and articles are also described.

Cooperative model between an application server and a database

Methods and systems of monitoring events occurring in a computer system are provided. An event monitoring instruction including a condition is parsed, the event monitoring instruction expressed using syntax defined in source code, the parsing resulting in an event channel to monitor and the condition. Then execution of an application is paused. The event channel is monitored until an event occurs on the event channel. Then an event handler for the event is run in response to the event occurring on the event channel. The condition is evaluated to determine whether the condition is satisfied. Execution of the application is resumed in response to the condition being satisfied.

Programming language conditional event dispatcher

A plurality of partitions can be defined in a database for a multi-tenant computing system provided on one or more processors such that each partition of the plurality of partitions is associated with only one business tenant of a set of business tenants supported by the multi-tenant system. The database can stored shared content that is shared among and accessible to all tenants of the multi-tenant computing system while tenant content for each business tenant can be stored in the database in one partition of the plurality of partitions. The one partition can be assigned to an associated business tenant. At least a portion of the tenant content can be unique to and associated with the associated business tenant. One or more errors can be generated to prevent tenant content associated with a first business tenant of the set of business tenants from being accessed by a second business tenant of the set of business tenants when an application code executed within the multi-tenant computing system comprises a construct that would otherwise enable cross-tenant access by the second business tenant to tenant content associated with the first business tenant. Related systems, methods, and computer program products are described.

Strict tenant isolation in multi-tenant enabled systems

A system, computer program product and method of processing function calls in a distributed application environment are provided. A number of function calls for communication from a sending application to a receiving application are queued in a database. Dependencies among at least a portion of the function calls that are being queued are determined while the function calls are stored in the queues. A schedule of execution of the function calls is then generated based on the determined dependencies.

Queued asynchronous remote function call dependency management

A computer system and computer program product executing a method for consistent and efficient management of program configuration and customizing data for a business application program. According to one method, an existing or newly created version of a global switch configuration is provided in a cache shared by one or more other programs. The cached switch configuration provides a configuration for a switch framework that governs access to one or more program functions of a business application. The cached switch configuration is then attached to the business application to provide an attached version of the switch configuration. Compatibility between the attached version of the switch configuration and the business application is determined. If compatibility exists, the business application program is executed in accordance with the attached version of the switch configuration.

Method for consistent and efficient management of program configuration and customizing data

A method and system for employing client interfaces for packages. In one embodiment, an access object associated with a service provided by a first package is located, where the service is seeking to access content residing at a second package. A client interface is then created at the second package using the access object. The client interface is used to provide access to the content by exposing the content to the service via the client interface.

Client interfaces for packages

A method and system for object generation in packages. In one embodiment, the process for generating an object in a package is initiated. The package is created and is associated with a target package. The object is generated into the package.
