The Tablespace feature-the ability to replicate data files directly between Oracle instances without unloading and loading data-was introduced in Oracle 8i and has since become a feature. Initially, the tablespace and destination databases to be transferred must have the same size module. Support for the increased number of module sizes in Oracle 9i overcomes this limitation. Now, in Oracle 10g, the limitations of the platform have also been largely r

Reason:The personal plan points Data Source of the knowledge base is 157 databases. However, based on Bi and other systems, a separate personal plan points of the knowledge base are copied on the 34, so each 157 change occurs, it is troublesome to manually change 34 databases. Therefore, a trigger was written in 157 to synchronously update the personal plan points of 34
