-execute the IMP, using the Indexs=n parameter to import objects other than index. Finally, go to Sql*plus, run the script you just edited, and build the index. This method is useful for importing index and constraints into the specified tablespace. 2. Change the default tablespace for the destination userThis is the way that people often ask questions. But the problem is not successful because of the lack of the following steps. first, recover the "UNLIMITED tablespace" permission for the desti

Before importing and exporting data, it is customary to check to see if our own machine can connect to a remote Oracle host, and the detection method is tnsping service_name. My machine is as follows:c:\users\zx>tnsping ORCLHost: lenovo-pc, service name: ORCLThe above operation is ping yourself, below we ping the remote host. How to use: Tnsping Ip/service_name, as follows:10.120. 56.203/ORCLHost and service names are marked by a red boxImporting data remotelySyntax format: Imp username/[email p
They have a common advantage is "change the whole, to avoid the input error" What are the two different?

OC-class definition and oc-DefinitionWe have already introduced a program HelloWorld: Keep in OC.
The biggest difference between OC and C is that it has the Object-Oriented function. When it comes to object-oriented, we have to talk about the class concept. If we have learned Java, so there is no stranger to the concepts of classes and objects, Because Java is a very pure object-oriented design language. I will not elaborate on the concepts of classe

Recently, when I was working on the preliminary code architecture of the cloud platform, I encountered a constant definition speed comparison problem, so I would like to make a comparison.The APC extension of PHP is described in the following section in the PHP manual:Http://cn.php.net/manual/zh/function.apc-define-constants.phpDefine () is notoriously slow. Since the main benefit of APC is to increase the performance of scripts/applications, this mec

To write a good C language, a beautiful macro definition is very important. Macro definitions can help us prevent errors, improve code portability and readability, and more.In the software development process, there are often common or common functions or code snippets that can be written as functions or encapsulated as macro definitions. So is the function good or the macro definition good? This requires u
