the function semop() itself? The /tmp/.VRTSTuxedo//PID directory exists, but there is no pidfile.BBL file, so it is proceeding to check for the required processes, whereby it does not find them and eventually faults: ffdc:20103: Tuxedo For HP note that it is advisable to adjust the 'maxdsiz' parameter to allow a process to allocate more memory for users data/objects MAXDSIZ = 536870912 MAXSSIZ = 67108864 For Digital Removing brace from the left of dcases Is there a performance difference in the 2 temp table initializations?

Does the process scheduler start well ?

This is a "wait-for-zero" operation: if semval is zero, the operation can immediately proceed. Another possibility is that such semaphore adjustments could be ignored altogether (somewhat analogously to failing when IPC_NOWAIT is specified for a semaphore operation). The elements of this structure are of type struct sembuf, containing the following members: unsigned short sem_num; /* semaphore number */ short sem_op; /* semaphore operation */ short sem_flg; /* operation Otherwise, semzcnt (the count of threads waiting until this semaphore's value becomes zero) is incremented by one and the thread sleeps until one of the following occurs: · semval becomes 0,

Libtux_cat:669: Error: Message Operation Failed Because Of The Invalid Message Queue Identifier

Code for semtest.c and semaphore.c are as given below ********************************************************************* /* semtest.c */ #define PROG_NAME "SEMTEST" #define TITLE "SEMTEST Semaphore Test Stub - Version 0.1 (10-Dec-1992)" #define USAGE "Usage: semtest c|o" Furthermore, if SEM_UNDO is specified for this operation, the system subtracts the value sem_op from the semaphore adjustment (semadj) value for this semaphore. Libtux_cat:271 semop() is never automatically restarted after being interrupted by a signal handler, regardless of the setting of the SA_RESTART flag when establishing a signal handler. Libtux_cat:268: Error: Failed To Stop Serving Before Linux 3.19, the default value for this limit was 32.

EACCES The calling process does not have the permissions required to perform the specified semaphore operations, and does not have the CAP_IPC_OWNER capability in the user namespace that governs its IPC A semaphore adjustment (semadj) value is a per-process, per-semaphore integer that is the negated sum of all operations performed on a semaphore specifying the SEM_UNDO flag. This bug is fixed in kernel 2.6.11. A description of the project, information about reporting bugs, and the latest version of this page, can be found at https://www.kernel.org/doc/man-pages/.

P semaphore failed Thanks. Even apache uses shared memory resources.I've attached a resource analysis script that lets you collect data over any time period you designate. Created a test program 'semtest.c'.

Looks like you have specified the value as mclnsetst01-dev, but in the process listing the Tuxedo server are coming up with a value of mclnsetst02-dev. It is a SUN V240 with dual 1.2 Ghz procs and 4GB RAM. What db and version ?

If it does not find the pidfile.BBL file, it will start looking for the required processes associated with the environment (BBL, PSAESRV, PSDSTSRV etc.).
