Abstract: Methods, systems, and computer program products for converting a database table are described. A data structure is accessed to obtain an identification of one or more differences of a source table in the database and a specified target table and a new field is appended to the source table for a field of the source table in need of conversion, the field of the source table in need of conversion having a name. A processor-driven trigger is created for the field of the source table in need of conversion and data is copied between the field of the source table in need of conversion and the corresponding new field using the processor-driven trigger.

Abstract: A zero downtime upgrade procedure is initiated that upgrades a first version of software executing on a source system comprising at least one source server to a second version of software executing on a target system comprising at least one target server. The source system initially starts operating in a read-write mode. Thereafter, concurrent with the operation of the source system, operation of the target system is initiated in a read-only mode. Operations of the source system are then ceased by ramping down activities of the source system. Upon cessation of operation of the source system, operation of the target system is initiated in a read-write mode.

Abstract: Methods, systems, and computer program products for converting a database table and implementing upgrades and/or migrations are described. A bridge schema comprising a bridge view for a table in a database of an original schema is created and a bridge application server instance is created, the bridge application server instance configured to utilize the bridge schema to access the table of the original schema. The table of the original schema is revised to conform to a specified target schema and a target application server instance configured to access the revised table is created.

Abstract: Various techniques are described for precisely locking database objects within a database during a system upgrade with the use of database freeze triggers. Some database freeze triggers can be utilized to lock transport requests while other database freeze triggers can be utilized to lock database objects such as exchange tables. For transport requests, techniques describe the use of a whitelist identify transport objects or transport object types which shall remain unblocked. As a result, a database freeze trigger can be generated for transport objects or transport object types that are not included in the whitelist. For database objects, techniques describe the identification of a tool or service which has been allowed during the upgrade. Database objects which can be modified during execution of the tool or service can be identified. Database freeze triggers can be generated for the database objects besides those identified.

Abstract: A zero downtime upgrade procedure upgrading a source system to a target system is initiated that prepares software for the target system in parallel to the operation of the source system. As part of the upgrade procedure, source tables of the source system are renamed. Thereafter, the renamed source tables are cloned for the target system. Further, the renamed source tables are equipped with database triggers to transfer data from the renamed source tables to the cloned tables used by the source system according to a source database schema. Next, the target tables are generated that include updated software content for later use by the target system while the source tables are used via a bridge database schema. Tables can then be shared between the source database schema accessed via the bridge database schema and the target system.

Abstract: Techniques for migrating data in a database include identifying an update to one or more data entries of a source table; determining that a status of a trigger associated with the source table indicates to update a logging table, and in response: updating, in a first transaction, (i) the one or more data entries of the source table, and (ii) one or more data entries of the logging table based on the user input, and copying content of the source table to a target table; and determining that the status indicates to update the target table, and in response: updating, in a second transaction, (i) the one or more data entries of the source table and (ii) one or more data entries of the target table based on the user input, and updating the content of the target table based on the one or more data entries of the logging table.

Abstract: In some example embodiments, a computerized method includes determining at least one of a read frequency, a write frequency and a data volume for data persistently stored. The data has a first format. The method also includes selecting a first type of data migration or a second type of data migration, wherein the selecting is derived from at least one of the read frequency, the write frequency and the data volume for the data persistently stored. The method includes transforming the data to a second format using the selected data migration. The method includes outputting the data for storage in machine-readable medium.

Abstract: A system and method for database migration is provided. In an example embodiment, the database migration technique may include execution modules having a first connection to a source database and a second connection to a target database, and orchestration modules adapted to identify first and second subsets of statements from a single storage table, wherein the first and second subsets of statements are executed by the execution modules during an uptime period of the source database.

Abstract: A zero downtime upgrade of a source system to a target system is initiated. The source system and the target system operate in a first database layer and a second database layer. Thereafter, differences in structure and/or database type are computed between a source table in the source system and a target table in the target system in each of the two different database layers. The data is then migrated, using the computing differences and in the second database layer, from the source table to the target table. The upgrade procedure is later terminated after completion of the migration of the data. Related apparatus, systems, techniques and articles are also described.
