20140279907 | Reducing Reading Of Database Logs By Persisting Long-Running Transaction Data - According to one embodiment of the present invention, a system reduces re-reading of database logs by persisting long running transaction data. The system processes the database log records of the database transaction log; generates a snapshot of the database log records at periodic intervals, wherein each snapshot includes database log records for pending transactions; and in response to an interruption in processing of the database log records, utilizes a snapshot to restore database log records for the pending transactions and resume processing of the database transaction log from a position succeeding the database log records of the selected snapshot. | 09-18-2014 |
20140379663 | REDUCING READING OF DATABASE LOGS BY PERSISTING LONG-RUNNING TRANSACTION DATA - According to one embodiment of the present invention, a system reduces re-reading of database logs by persisting long running transaction data. The system processes the database log records of the database transaction log; generates a snapshot of the database log records at periodic intervals, wherein each snapshot includes database log records for pending transactions; and in response to an interruption in processing of the database log records, utilizes a snapshot to restore database log records for the pending transactions and resume processing of the database transaction log from a position succeeding the database log records of the selected snapshot. | 12-25-2014 |
20150026115 | CREATION OF CHANGE-BASED DATA INTEGRATION JOBS - A computer software implemented method for transforming a first extract transform load (ETL) job having at least some unload transform load (UTL) portions. The method includes the following steps: (i) decomposing the first ETL job into an intermediate set of one or more jobs; and (ii) for each job of the intermediate set, transforming the job into a transactionally equivalent job to yield a final set of one or more jobs. The decomposing is performed so that each job of the intermediate jobs set is a Simple UTL job. The transforming is performed so that each job of the final set includes no UTL portions. | 01-22-2015 |
20150095286 | DATABASE AUDITING FOR BULK OPERATIONS - A method facilitates auditing of database transactions by maintaining logical consistency between a source database table and a shadow database table. A bulk command is received that specifies edits to a plurality of rows in the source database table. The bulk command is executed on the source database table. The shadow database table is queried to obtain an indication of the plurality of rows edited by the bulk command. The indication is stored as part of an audit trail for the source database table. | 04-02-2015 |
20150095287 | DATABASE AUDITING FOR BULK OPERATIONS - A method facilitates auditing of database transactions by maintaining logical consistency between a source database table and a shadow database table. A bulk command is received that specifies edits to a plurality of rows in the source database table. The bulk command is executed on the source database table. The shadow database table is queried to obtain an indication of the plurality of rows edited by the bulk command. The indication is stored as part of an audit trail for the source database table. | 04-02-2015 |
20150178121 | REPLICATION OF BATCH JOBS OF COMPUTING SYSTEMS - A method for replicating the effect of batch jobs using a replication agent is provided. The method comprises a replicating agent maintaining a maximum level in rows and a minimum level in rows for one or more columns in a database table of one or more database systems. The replicating agent further analyzes a mapping defined in the replicating agent to identify source columns of a source database system of the one or more database systems which are mapped to a target column of a target database system of the one or more database systems. According to at least one embodiment, the replicating agent further identifies a logical clause of the source database system and the target database system to define a range refresh. The replication agent further initiates the defined range refresh. | 06-25-2015 |
20150178363 | REPLICATION OF BATCH JOBS OF COMPUTING SYSTEMS - A computer-implemented method for replicating the effect of batch jobs using a replication agent is provided. The computer-implemented method comprises a replicating agent maintaining a maximum level in rows and a minimum level in rows for one or more columns in a database table of one or more database systems. The replicating agent further analyzes a mapping defined in the replicating agent to identify source columns of a source database system of the one or more database systems which are mapped to a target column of a target database system of the one or more database systems. According to at least one embodiment, the replicating agent further identifies a logical clause of the source database system and the target database system to define a range refresh. The replication agent further initiates the defined range refresh. | 06-25-2015 |
20150261838 | MANAGING REPLICATION CONFIGURATION AVAILABILITY - A computer-implemented method, carried out by one or more processors, for managing replication configurations. In an embodiment, the method comprises receiving, by one or more processors, a replication configuration for replicating data, wherein the replication configuration defines at least a target table in a target database based on a source table in a source database; initializing, by one or more processors, a federated view, wherein the federated view is based on at least the source table in the source database as defined in the replication configuration; utilizing, by one or more processors, the federated view to satisfy requesting applications, where requesting applications obtain data from the federated view; responsive to determining the replication of data is in spec, utilizing, by one or more processors, the target table in the target database to satisfy requesting applications. | 09-17-2015 |
