Prerequisites: 1). the source and target Oracle Database listening starts.2). gg installation directory:/u01/app/ogg3) The copied table must have a primary key.4) check whether the extraction log directory configured by the process is valid. If the Process configuration is correct, Directory inconsistency may cause the replication to fail.5). Operating SystemRhel 5.4X64 (2.6.18

GXPT is a distributed system that temporarily includes the permission system, basic system, evaluation system, and examination system. Each system has its own oracle database. Our group is responsible for the evaluation system, and the normal evaluation system needs to rely on the permission system and basic system. The specific business is not explained here. The evaluation activities are coming soon. The basic system enters real data into the basic

Schema-level replication can be done through DBMS_STREAMS_ADM. Maintain_schemas created, after the space-level trial of the previous table, the creation of a schema-level replication environment is relatively straightforward. The examples in this chapter continue to follow the environment in the previous chapter (primarily the Oracle environment, where the previ
