Oracle single table stream replication is completed. Due to the many steps of oracle stream operations, many problems have been encountered before, Failed because I did not clarify my thinking or did not understand this. For important tables, stream replication is similar to the logging uard Application Log, master ser

Recently, because of the job needs, the boss asked the Oracle database on the server to migrate data to another server, I am not very familiar with Oracle, the migration of the database This is a matter of time spent, but also on the internet to inquire a lot of information. All kinds of moves are exhausted or not successfully migrated.Finally, the spirit of the dead horse as a live horse doctor, the

Oracle table organization and Data Replication 1. Copy the table structure and data to generate a new table: Create table table_name_new as select * from table_name_old; 2. copy only the table structure: Create table table_name_new as select * from table_name_old where 1 = 2; Or: create table table_name_new like table_name_old 3. Copy table data only: If the two tables have the same structure: Inser

Subject design Dblink to soa-suite the premise is that the Dblink both sides have a separate interface table, the effect of migration is, by a mediator trigger event , after this event triggered by the BPEL part to capture this event, Within this BPEL component, the Dblink functions of logging, data reading, data conversion, and data writing are accomplished through the collaboration of Dbadapter (log parts, read parts, write parts). 2.

You may be running an Oracle 10g Release 2 database server, but supporting some applications may have been written very early. Data tables created prior to Oracle 8i typically have a long data type to store large text. With the introduction of the large Object (LOB) data type, the long and long raw data types are discarded. If you are copying a data table that uses a Long data type, then using the CREATE t

Stream is an extended application of Oracle's Message Queuing (also known as Oracle Advanced Queue) technology. Oracle Message Queuing resolves event management through publish/subscribe. Stream replication is just a data sharing technique based on it, or it can be used as a flexible and customizable high-availability scenario. It enables database-level, schema-l

The wrapper defines a library that is responsible for communicating the local database to the remote database. The wrapper performs many tasks, such as: it can connect to the data source, and the wrapper applies the
