According to Oracle's documentation, the data pump in different ways to export imports, performance can be significantly different, this time just have the opportunity to test, migration table space, direct path, external table, and database chain export, import performance differences. This test network_link how to import. First clear the user and tablespace imported from the previous article, and re-establish the test user and tablespace. sql> DR

written in front of the words: See the title so long may be a little crazy, yes, I just learned this article when there are some do not understand, what is the layout of the pump? Edit each template then what is a custom adapter? Below we begin to learn the content of this article Preferred previous picture to achieve effect: Logical parsing: First of all, the above diagram is the final implementation of the effect, a bit like our contacts cont

This includes object tables is partitioned. A domain index exists for a LOB column. A table is in a cluster. There is an active trigger on a

(In the default mode, only one process is visible) all the worker processes synchronize the data out and display their progress on the status screen.It is important to separate the input/output channels that access the data files and dump the directory file system. Otherwise, the overhead associated with maintaining the data

It is better than the imp/exp of the advantages of the way to say---faster!Unfortunately, I exported the data when the error, I wipe, this special is embarrassing. So, divine skill at first glance, brother Hong is good at solving the problem have wood?Yes? At first glance thi

When importing data using the IMPDP data pump in Oracle, it is assumed that the user was created before the import, prompting the error: "ORA-31684: Object type already exists." Such as:In fact, this problem is not serious, can not create a user first, import when you specify a Super user import:impdp system/123456

1. Relationship of Parts (part), Entity (Instance) and set (Assembly) (13.3.1) A model can include many parts (part), but it can contain only one set (Assembly). This collection is composed of many entities (Instance), and these entities (Instance) are formed by parts (part) that are specified in the overall coordinate system. For example, if a part is a brick, t

Events and applications of 16.4.2 Tdbgrid components Tdbgrid parts in the same time with many important attributes, Delphi also gave it a number of events to control the user in the Tdbgrid part of the operation, we have some of these events to write handlers, can effectively control the behavior of Tdbgrid parts. Because at one time in the Tdbgrid part is displaying multiple fields in multiple records and

According to Oracle's documentation, the data pump in different ways to export imports, performance can be significantly different, this time just have the opportunity to test, migration table space, direct path, external table, and database chain export, import performance differences. This article introduces the test environment. Both the source and target database versions are 10.2.0.3, there is no version difference, the character set is ZHS16GB

Recently checked a blog before, unexpectedly found this bug was I forget, after a year to continue to solve this problem. Based on the analysis process described in the previous article, it is generally possible to confirm that the statistics of these partitioned tables are related to themselves. Since the current database is exported from 920 environment exp, IMP is imported into the same version of the intermediate database and eventually imported into the current database through the data
