Generally speaking, the air conditioning system is designed according to the full load, but the actual operation, the full load operation time is less than 3%, the air conditioning equipment most of the time in the case of a far lower than the rated load operation. Under partial load, although the chiller can adjust the corresponding cooling output according to the actual load, but the flow configuration of the conventional cold water system in the evaporator side of the chiller is fixed, the ch

How to Diagnose Oracle Data Pump-How to add diagnostic information to the Data Pump, diagnosepump- There are still many bugs in the 11g Data Pump (expdp/impdp), and we often encounter inexplicable card death, which makes people feel overwhelmed. I recently read an article, in fact, you can track logs when exporting and importing data from a data

Oracle's 11GR2 version does not make much of a change to the data pump, mainly by adding support for the original version parameters and removing some small restrictions. This article introduces the data pump to import the new data_options parameters. Prior to 11.2, the data pump import provided only one data_options--skip_constraint_errors, and in 11.2, Data_o

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 discusses the effect of parallelism on the export of data pumps. Write a few articles before the data pump also know not much, recently read the document found that the parallel settings are also skilled, if set reasonable, you can significantly

For example: Int [] array = {,}, divided into two parts: {, 4}, {7}, the difference is 1. Reference 1: Section 2.18 of the beauty of programming, but the

On the itpub saw someone raise this question, can use the data pump to export a query result. In fact, the data pump really has this function. Establish a simple test environment: sql> CREATE TABLE T1 2 (ID number, NAME VARCHAR2 (30)); Table created. Sql> INSERT into T1 2 SELECT rownum, Tname 3 from TAB; Created rows. sql> CREATE TABLE T2 2 (ID number, NAME VARCHAR2 (30)); Table created. Sql> IN

Starting from 10 Gb, Oracle provides more efficient Data Pump (expdp/impdp) for Data import and export. The old exp/imp can also be used, but it is not recommended. Note: expdp/impdp AND exp/imp are incompatible. In other words, exp exported files can only be imported using imp, and expdp exported files can only be imported using impdp.
