Client access to the EJB deployed on the apusic. While this is one of the simplest aspects of apusic and CORBA interoperability and does not involve security and transactional propagation, it has shown the APUSIC capabilities and general steps for development in interoperability. First, introduce the server and client development environment. The server-side environment is: Windows Server JDK1.4.2 Apusic Application Server 3.0 The client's environment is: Windows Professional JDK1.4.2 T

Recently, when using Cold Standby tar for Oracle database migration, You need to filter out the files exported by datapump under the current database file, otherwise, a large tar file will be generated and the network transmission time will be consumed. In fact, the tar command provides a filtering function, but many people do not know it because the filtering function is usually used less. This article describes how to filter unwanted files or folders under the tar command. 1. Demo Environment

The operating system chooses Windows (of course, you can also choose HP UNIX, Linux, or AIX). 　　 Program Implementation 　　 IDL IDL is the protocol that the CORBA server and the client make the request call, and the client and the service can communicate seamlessly without any relation to the development language

can pay more attention to program algorithms and logic, rather than network details.What we need to do is the simplest client RPC call, define the interface file of the function we want to call, and then call the NetpwPathCanonicalize () function of the target host, according to our local overflow, the specially constructed string containing the shellcode is passed in, so the remote host will overflow when executing this function, and will execute our shellcode!RPC client development process (f

. CORBA and DCOM are both designed for client/server style communication among distributed objects. in both technologies, a client invokes a method that is implemented by a remote object that acts as a server. the interface for such an object providing the service is defined in an Interface Definition Language (IDL ). this keeps the object implementations hidden from the client. both CORBA and COM communications are implemented like RPC and methods of

In subsequent examples you will need to be able to compile type libraries and reference them from VB projects. in this example you will compile an IDL file using the Microsoft IDL compiler and register the resulting type library file with windows, thereby allowing you to reference the Type Library in VB just like an ActiveX component. but first, you may require some essential background information. the mid

, which calls the actual code in windows through LPC. This structure can isolate user processes from Windows code. The structure used by COM is similar to that used by the customer to communicate with the DLL of the same imitation component. This dll can adjust parameters and call LPC for the customer. A proxy is a component with the same behavior as another component. The proxy must be in the DLL format because they need to access the address space of the client process to adjust the data trans

If the system does not have the yum-yinstalldstat tool, install dstat. the software is small and exquisite. the package size is only 144 KB, and the installation size is 660 KB. By default, this tool dynamically displays the CPU, disk, net, page, and system load conditions, as shown in the following figure. of course, there will be different colors, which is relatively intuitive, for the moment, we will directly copy and integrate the product. We also hope that you will see Guan Haihan, and you

Aidl (Android Interface Definition Language) is an IDL language used to generate interprocess communication between two processes on Android devices (interprocess communication, IPC) The code. You can use Aidl to generate serializable parameters if you want to invoke the operation of another process (such as a service) object in one process (for example, activity). This article briefly introduces the use of Aidl.1. New Iremoteservice.aidlPackage Com.t
