If a table to be synchronized is a replication table without a primary key in GaussDB, the task will fail. System schemas (pg_toast, cstore, snapshot, sys, dbms_job, dbms_perf, pg_catalog, information_schema, utl_file, dbms_output, dbms_random, utl_raw, dbms_sql, dbms_lob, dbe_...
A client/server architecture is similar to the traditional centralized architecture in that the DBMS resides on a single computer. In fact, many of today’s mainframes actually function as large, fast servers. The need to handle large data sets still exists although the location of some of the...
nonlinear equations/ C4130 Interpolation and function approximation (numerical analysis) C6160 Database management systems (DBMS)In this paper we analyze Optimistic Concurrency Control (OCC) schemes based on certification. We allow two data access schemes referred to as static and dynamic. A static ...
Data Management in Peer-to-Peer Data Integration Systems Decentralized data management has been addressed during the years by means of several technical solutions, ranging from distributed DBMSs, to mediator-base...

Because Amazon RDS is a managed service, Amazon RDS for Oracle doesn’t supportDBMS_SWRF_INTERNAL.AWR_LOADas of this writing. Therefore, for this demo, we create a centralized repository on Oracle hosted on Amazon EC2. The database user should have privile...
The effect of concurrency control methods on the performance of computer systems is analyzed in the context of a centralized database with a static lock request policy, i.e., database transactions should acquire all locks before their activation. In the lock conflict model the L locks required ...
Do not synchronize unlogged tables in the incremental phase. A user-defined table that has no primary key and is a partitioned table cannot be synchronized. Otherwise, data may be inconsistent or the task may fail. System schemas (pg_toast, cstore, snapshot, sys, dbms_job, dbms_perf, ...
The AAA server is coupled with a DBMS system that stores user authentication, authorization and accounting information in a standard format. Authentication and authorization are performed using a five phase process comprising the phases: Augmentation; Selection; Authentication; Authorization and Confirmation...
