To correct the problem, first use the steps below to determine if you are experiencing this specific crash, because a reference to BLK_OPENED_NOTE can occur in other situations. The best artical to explain shared memory in Oracle.

Prior to this type of crash condition occurring, the following errors are typically reported in the console log: Insufficient memory Maximum number of memory segments that Notes can support has been Oracle will need exactly as many semaphores as the value of the processes "init.ora" parameter. The size of the SGA is the sum of the sizes of the 4 portions.

Sign in to participate Previous Next Panic error: can not attached to shared memory.. For example, if SEMMSL=25 and SEMMNI=10, total # of semaphores required (sum of PROCESSES) must not exceed 250 (10 semaphore sets * 25 semaphores/set). Upon awakening, the process will reattempt to turn the flag on, possibly suceeding or possibly sleeping again. To see what semaphores have been allocated, use the Unix command 'ipcs -b'.

Once this occurs, Domino will panic with one of the below messages: PANIC: Insufficient memory PANIC: Cannot attach to shared memory region, due to insufficient access (probably owned by another user Afterwards submit the NSD(s), console log and memory dumps from the incident to Lotus support.

For better performance, reboot the server after configuring enough Huge Pages. 00:0000:00000:00000:2012/12/10 09:57:33.88 kernel os_create_region: cannot lock shared memory region '/opt/sybase/ASE-15_0/pqbsyb1.krg' into physical memory. http://gpscheduler.com/cannot-attach/cannot-attach-to-or-create-shared-memory.html The maximum # of semaphores that can be allocated will be the lesser of (SEMMSL*SEMMNI) or SEMMNS. However, if the SGASIZE is larger than the configured SHMMAX, this will obviously fail. Once you have noted ALL of the identifiers for ALL of the instances which are up and running, compare these id numbers to those in the "ipcs -b" listing.

If all shared memory is used, Oracle will use swap. One-segment 2. Recommended values of kernel parameters for Shared memory in Oracle 8i SHMMAX= max value of shared memory segment = .5 * size of physical memory SHMMIN= min size of shared memory

Semaphores are allocated in sets.

Great job! » Log in to post comments What about copiright? However, I can't enter in-process mode either by command line option or using GammaRay launcher. In this case, the SGA will need to be placed in multiple shared memory segments, and Oracle proceeds to the next memory model for the SGA. If the output of ipcs -s is large (> 100 lines), then something is wrong.

The entry that does not have a running instance to match is the orphaned entry. According to the comments in header file, both Probe::instance() and Probe::isValidObject(caller) requires locking on Probe::objectLock(), what type should I lock, read or write? Semaphores can be thought of as flags (hence their name, semaphores). If the issue reoccurs with the debug enabled then perform step 1 and restart server.
