This happens if there is a bug in the calling routine. The process must have an effective ID of owner, creator or superuser to perform this command. Not all named file system objects can be mapped. SEE ALSO ubbconfig (5), tmloadcf (1), tmconfig (1) 735 ERROR: [Queue parameter error in internal routine] DESCRIPTION See message 728 for an explanation.

The amount of memory required by TUXEDO System/T is influenced by the parameters given in the UBBCONFIG file. MAP_PRIVATE specifies that an initial write to the mapped area creates a copy of the page and all writes reference the copy. Inquire about the state of shared memory with shmctl.c. is interpreted as hexadecimal,\n"); (void) fprintf(stderr, "\t0...

The original owner of a shared memory segment can assign ownership to another user with shmctl(). p->shmaddr = shmat(p->shmid, p->shmaddr, p->shmflg); if(p->shmaddr == (char *)-1) { perror("shmop: shmat failed"); nap--; } else (void) fprintf(stderr, "shmop: shmat returned %#8.8x\n", p->shmaddr); ... ACTION Make sure that the path name of the new server executable is the same as the path name for the existing server(s) on the queue used by the new server. Because they are very light weight, the most efficient synchronization mechanisms in Solaris 2.x are the threads library ones.

ACTION Contact your TUXEDO System Technical Support. 704 ERROR: Operating system parameter for message queues too small DESCRIPTION The UNIX System kernel parameters related to message queues are set too low. ResolutionDo not connect to the same database using shared memory more than once.  Alternatively, create and use an alias for the target DB.  For example: CREATE ALIAS s2k02 FOR DATABASE s2k01

Reply Quote 0 SGaist Lifetime Qt Champion last edited by Are you sure that the process that created the QSharedMemory is still running while your second process tries to attach it this contact form It is prototyped as follows: int shmctl(int shmid, int cmd, struct shmid_ds *buf); The process must have an effective shmid of owner, creator or superuser to perform this command. Increase the space on the swap device. This should not happen during normal system operation.

Example The onconfig parameter SHMVIRTSIZE and the kernel parameter SHMMAX are set to 167772160 and 33554432 bytes respectively.

A mapping type is retained across a fork(). But I cannot get a second process to attach that same existing segment. My Shared.h #ifndef MYSHARED_H_INCLUDED #define MYSHARED_H_INCLUDED #include #include #include #define PERM (S_IRWXU | S_IRGRP) #define MySharedKey 564732 #define SIZE 512 // 512 bytes struct MyShared { char buf[SIZE]; Devices that cannot be treated as storage, such as terminal and network device files, are examples of objects that cannot be mapped.

First open() the file, then mmap() it with appropriate access and sharing options Away you go. I found a mention about it in some thread but no solution (I think it was deleted) Help, please. key = " << tKey << std::endl; size_t nSharedMemorySize = 10000; int id = shmget(tKey, nSharedMemorySize, 0); if (id == -1) { std::cerr << "ERROR: shmget() failed (WILL TRY TO CREATE Check This Out Oftentimes, a network that is inoperative or slow may result in a BBL response problem. 733 ERROR: [Type information invalid] DESCRIPTION The internal routine to create an entry in the bulletin

The services currently offered on a queue can be determined through the tmadmin (1) printservice command with the -q option. The attach() fails. Only users with topic management privileges can see it. I am assuming that the 1st process does not put some kind of a lock on that node because that would be senseless.

Like any other portion of the process's address space, no page of the file is not actually loaded into memory until a page fault forces this action. Reduce the memory usage on the machine or increase the amount of physical memory on the machine. IPC_STAT -- Return the status information contained in the control structure and place it in the buffer pointed to by buf. you get the EINVAL error only if it's larger. (3) the mode flags are only relevant when you create the segment the first time (mostly sure). (4) The fact that shmget()

The flags MAP_SHARED and MAP_PRIVATE specify the mapping type, and one of them must be specified. Reduce the memory usage on the machine or increase the amount of physical memory on the machine. Creating and Using Mappings mmap() establishes a mapping of a named file system object (or part of one) into a process address space. So that eliminates one of your complaints.
