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

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

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

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
