Two problems encountered during impdp Import Two days ago, you need to import the data dump exported from a remote test database using expdp to a local test environment. Some problems are encountered, which is worth a summary. Environment Introduction: 1. Data volume: 10 + tables, 2. Both the source and target databases are 11.2.0.4 3.

According to business requirements, all objects under the test user on the database are replicated to a new user TEST2, but no table data is required. The idea is to first use the EXPDP content=metadata_only parameters to export metadata, and then use IMPDP remap_schema=test:test2 to convert to complete the business requirements. Once submitted to the business unit, it is also requested that the table space used by the TEST2 business table be assigned

cannot be moved. However, from Oracle Database 10 Gb, you can use the alter tablespace RENAME command to modify the name of the source data table space or destination database tablespace. The system tablespace and the tablespace of the Sys user object cannot be moved. If you want to move a tablespace to another operating system, you must set the initialization parameter compatible to 10.0 or above. To migrate the table space tbs01 in the orcl database to the demo database, perform the follow

Some time ago in a migration of data pump and exp, found that the difference in efficiency is quite large. Here is an example of a simple comparison. This article compares the differences between IMP and IMPDP import. The comparison of exp and data pump export, you can see that the data pump export speed and direct path, compared to the speed is not the essence of improvement, the following look at the da

The company's system uses orcalce 10 Gb. However, during installation, the default tablespace of the created solution (User old_user) is system, and expdp and impdp are used to transfer it to the new tablespace. Assume that the user name is new_user. The default tablespace is new_tablespace. 0. Before using expdp and impdp, you must set the directory object and grant the user the read and write pe

Due to objective reasons of disk space, it is not possible to use rman and expdp to generate landing files for recovery or import operations. Therefore, impdp is used to import data using network_link, this method is really good, and because impdp can run directly on the server background, it can be unattended. You only need to check the logfile the next day. Click here to create dblink. Oracle $
