HP DCE/9000 Version 1.8 Application Development Tools for HP-UX 11i Release Note Developing DCE Applications with HP DCE/9000 Developing DCE Applications with HP DCE/9000 This chapter provides information about developing, building, and debugging DCE applications with HP DCE/9000.
HP DCE/9000 Version 1.8 Application Development Tools for HP-UX 11i Release Note Developing DCE Applications with HP DCE/9000 • Source code that is built into applications that use the CDS, RPC, or security APIs must include . This is necessary because the DCE RPC runtime library creates a small number of private threads, on both the client and server sides of an application. • The DCE header files should be included as .
HP DCE/9000 Version 1.8 Application Development Tools for HP-UX 11i Release Note Developing DCE Applications with HP DCE/9000 Applications. • To debug an HP DCE threads application with DDE, use the -dce_thread option. By default, DDE assumes that the application is single- or kernel-threaded. The debug and dde commands have been extended to take the -dce_thread option. For example:debug -dce_thread averagedde -dce_thread average See Section 3.2.
HP DCE/9000 Version 1.8 Application Development Tools for HP-UX 11i Release Note Developing DCE Applications with HP DCE/9000 • DCE CMA exceptions should never be allowed to propagate into a C++ scope. Allowing this to happen could result in destructors failing to be executed. This can lead to memory leaks and unexpected behavior. For example, suppose some C++ code makes a call to a C function. Within this C function, a CMA exception can be raised.
HP DCE/9000 Version 1.8 Application Development Tools for HP-UX 11i Release Note Developing DCE Applications with HP DCE/9000 information. Performance trade-offs in CDS's usage of memory, disk, cache, the network, and time-outs are optimized to this very specialized purpose. The generality of the application programming interfaces to CDS masks the specificity of this purpose, and gives CDS the appearance of a general-purpose database system.
HP DCE/9000 Version 1.8 Application Development Tools for HP-UX 11i Release Note Developing DCE Applications with HP DCE/9000 timestamp should be between 0 to 5000 ms (milliseconds). Typically 2000 ms is used in most cases. RPC_RESTRICTED_PORTS Environment Variable The capability to restrict the assignment of endpoints to those in a user-specified set was added to RPC in OSF DCE 1.0.3.
HP DCE/9000 Version 1.8 Application Development Tools for HP-UX 11i Release Note Developing DCE Applications with HP DCE/9000 • If the client specified DCE secret key authentication and the server specified no authentication, then the runtime will reject the call, and it will never reach the manager routine. • If both client and server specified DCE secret key authentication, then authentication will be carried out by the RPC runtime transparently.
HP DCE/9000 Version 1.8 Application Development Tools for HP-UX 11i Release Note Developing DCE Applications with HP DCE/9000 export RPC_SUPPORTED_NETADDRS=ip:10.3.2.1 will force any servers started in the current shell to support only the addresses associated with the name myhost and the network address 10.3.2.1. Calling exec() from a DCE Application Care must be used when calling exec() from a DCE application.
HP DCE/9000 Version 1.8 Application Development Tools for HP-UX 11i Release Note Developing DCE Applications with HP DCE/9000 • On the server side, the only supported behavior is for a server thread to fork and exec, with no use of RPC in the child of the fork until after the exec. File Locking The HP DCE Threads fcntl() wrapper does not provide for thread-synchronous file locking. The entire process will block when a call to fcntl() specifies F_SETLKW and the file is currently locked by another process.
HP DCE/9000 Version 1.8 Application Development Tools for HP-UX 11i Release Note Developing DCE Applications with HP DCE/9000 Because the semop() wrapper adds the IPC_NOWAIT option before performing the semop() system call, the value of semncnt and semzcnt should not be trusted when using semop() to perform semaphore operations. signal() Use of the signal() system call is not supported by HP DCE Threads, as it can interfere with signal handlers that are installed by Threads.
