Progress KB - Calculating SEMMSL, SEMMNS and SEMMN

SEMMSL is the maximum number of semaphores allowed per semaphore identifier (semaphore set). SEMMNS is the total number of semaphores allowed for the system. SEMMNU is the maximum number of semaphore undo structures allowed for the system. Semaphore calculation requirements for Progress DESCRIPTION The semmns tunable specifies the maximum total individual System V IPC system-wide semaphores which can be assigned by applications. Semaphores are assigned in sets associated with an ID. Thus semaphores can be distributed in any manner across the range of IDs with one or more per ID Semaphores are assigned in sets associated with an ID. Thus semaphores can be distributed in any manner across the range of IDs with one or more per ID. There is no reason to specify semmns less than semmni (the maximum number of identifiers) as each ID requires at least one semaphore

SEMMNS is the result of SEMMSL multiplied by SEMMNI. The database manager requires that the number of arrays (SEMMNI) be increased as necessary SEMMNS is the setting for the total number of Semaphores allowed system wide and may differe between versions. Oracle Support typically does not recommend specific values for semaphore kernel parameters. Instead, use the information provided in this document to set the parameters to values that are appropriate for your operating environment A semaphore is a term used in UNIX for a variable which acts as a counter.Ex.suppose two processes try to access the same file simultaneously.The value of the semaphore is initialized by the first process when the file is in access by it

What is the maximum amount of value assigned to SEMMNS ? How to calculate if SEMMNS assigned for semaphore is too much for a system ? Should the value of SEMMNS be determined as per the kernel code: #define SEMMNS (SEMMNI*SEMMSL) /* <= INT_MAX max # of semaphores in system */ Environment. Red Hat Enterprise Linux(All version) SEMMNS: maximum number of semaphores, system wide. SEMOPM: maximum number of operations in one semop call. SEMMNI: number of semaphore identifiers (or arrays), system wide. These parameters are set, all together, through kernel.sem which holds the values, separated through whitespace, as follows: SEMMSL SEMMNS SEMOPM SEMMNI. Not used or not. Setting SEMMNS to 32000 ensures that SEMMSL * SEMMNI (250*128=32000) semaphores can be be used. Therefore it is recommended to set SEMMNS to at least 32000 for 9i and 10g databases on x86 and x86-64 platforms Semaphores are data structures within the operating system that function like signals for memory process communications. For Oracle, semaphores tell the Oracle processes when to stop, wait or start operations. In addition, semaphores tell Oracle processes when they are to resume processing. Each Oracle process has its own semaphore assigned to it

SEMMNS - A system-wide limit on the number of semaphores in all semaphore sets. The maximum number of sempahores in the system. SEMOPM - The maximum number of operations in a single semop call. SEMMNI - A system-widerff limit on the maximum number of semaphore identifiers (sempahore sets SEMMNS - A system-wide limit on the number of semaphores in all semaphore sets.

SEMMNU is the maximum number of semaphore undo structures allowed for the system. Semaphore calculation requirements for Progress: SEMMS

Set seminfo_semmns, the maximum number Each HADB node needs eight semaphores SEMMNS = SEMMSL * SEMMNI The SEMOPM and SEMMSL parameter values must be equal. If any applications or databases are running on the client, the parameters must be increased accordingly Kernel Parameters to set semaphore limits The kernel parameters to set the semaphore limits are: kernel.sem = SEMMSL SEMMNS SEMOPM SEMMNI SEMMSL - max semaphores per array SEMMNS - max semaphores system wide SEMOPM - max ops per semop call SEMMNI - max number of array The specific parameters, SEMMNS and SEMMNU control the number of semaphores provided by the system for use by the database servers. The user interface, scoadmin, does not provide access to these parameters. Which means they need to be changed manually. This can be done via two methods: Method 1-----Use idtune to modify the kernel parameter

The sysctl command is used to view, set, and automated kernel settings in the /proc/sys/ directory. To get a quick overview of all settings configurable in the /proc/sys/ directory, type the sysctl -a command as root. This will create a large, comprehensive list.

I just updated one of my legacy developement AIX 4.3.3 systems with the latest AIX 4.3.3.11. Since the reboot the DBA has semaphore errors in the database log
  2. SEMMNS is the result of SEMMSL multiplied by SEMMNI. The database manager requires that the number of arrays (SEMMNI) be increased as necessary. Typically, SEMMNI should be twice the maximum number of connections allowed (MAXAGENTS) multiplied by the number of logical partitions on the database server computer plus the number of local.
  3. semaphore acts as a synchronization tool in IPC systems with the help of which we can ensure that a critical section can be accessed by the processes in a mutually exclusive way. It is simply a variable or abstract data type used to control access to a common resource by multiple processes in interprocess communication
  4. For example, the requirement is to set semmns parameter to a value of 50000. First, check the current running Value. You can confirm using the kctune command if the value can be change Immediately or at Next Boot. You should also confirm here at that Value on Next Boot is the one you specifically set

SEMMNS: maximum number of semaphores, system wide. SEMOPM: maximum number of operations in one semop call. SEMMNI: number of semaphore identifiers (or arrays), system wide. These parameters are set, all together, through kernel.sem which holds the values, separated through whitespace, as follows: SEMMSL SEMMNS SEMOPM SEMMNI # Red Hat Enterprise Linux 3.0 and CentOS 3.x kernel.shmmax = 2147483648 kernel.shmmni = 4096 kernel.shmall = 2097152 kernel.shmmin = 1 kernel.shmseg = 10 # semaphores: semmsl, semmns, semopm, semmni kernel.sem = 250 32000 100 128 fs.file-max = 65536 # Red Hat Enterprise Linux 4.0 and CentOS 4.x kernel.shmmax = 536870912 kernel.shmmni = 4096. Description The semget () system call returns the semaphore set identifier associated with the argument key. A new set of nsems semaphores is created if key has the value IPC_PRIVATE or if no existing semaphore set is associated with key and IPC_CREAT is specified in semflg

The last value is the number of database server utilities such as ONSTAT and ONCHECK that may connect concurrently

SEMMNS: System wide maximum number of semaphores: policy dependent (on Linux, this limit can be read and modified via the second field of /proc/sys/kernel/sem). Values greater than SEMMSL * SEMMNI makes it irrelevant. BUGS The name choice IPC_PRIVATE was perhaps unfortunate, IPC_NEW would more clearly show its function SEMMNS defines how many semaphores can be allocated on the system at one time. One value that is not mentioned below is SEMMAP. This keeps track of unused semaphores. This could cause potential problems for you if you have a high SEMMNS value The most significant parameter is the semmns semaphore parameter, which determines the number of semaphores in the entire system. The default configuration allows 1000 semaphores in concurrent use. The default semmni parameter value is 1000.

SHMMAX is the maximum size of a shared memory segment on a Linux system whereas SHMALL is the maximum allocation of shared memory pages on a syste semmns determines the maximum number of allowable semaphores system-wide. Because semmni is the maximum number of all possible semaphore sets, and semmsl is the maximum number of semaphores per set, the maximum total number of semaphores overall should not be greater than the product of semmni and semmsl System V semaphores are allocated by creating groups of individual semaphores. semmni above controls the maximum number of semaphore groups, and semmns controls the maximum total number of semaphores (within any and all groups). Each RTI Connext application that has shared memory enabled allocates 2 groups of 1 semaphore each (per domain) 1 - About On Linux, A semaphore is a System V IPC object that is used to control utilization of a particular process. Semaphores are a shareable resource that take on a non-negative integer value. They are manipulated by the P (wait) and V (signal) functions, which decrement and increment the semaphore, respectively kernel.shmall = 2097152 kernel.shmmax = 2147483648 kernel.shmmni = 4096 kernel.msgmni = 2878 kernel.msgmax = 8192 kernel.msgmnb = 65535 # semaphores: semmsl, semmns, semopm, semmni kernel.sem = 250 32000 100 142 fs.file-max = 131072 net.ipv4.ip_local_port_range = 1024 65000 net.core.rmem_default=262144 net.core.rmem_max=262144 net.core.wmem.

It occurs when either the system limit for the maximum number of semaphore sets (SEMMNI), or the system wide maximum number of semaphores (SEMMNS), would be exceeded. You need to raise the respective kernel parameter. Alternatively, reduce PostgreSQL's consumption of semaphores by reducing its max_connections parameter Find answers to Is ulimit -n (nofiles(descriptors)) = to the solaris kernel set shmsys:shminfo_semmns or what would be the equivalent? from the expert community at Experts Exchang set shmsys:shminfo_shmmax = 40000000 set shmsys:shminfo_shmmni = 180 set shmsys:shminfo_shmseg = 60 set semsys:seminfo_semmni = 320 set semsys:seminfo_semmns = 670 set semsys:seminfo_semmnu = 542 set semsys:seminfo_semmsl = 35 set msgsys:msginfo_msgmax = 2048 set msgsys:msginfo_msgmnb = 4096 set msgsys:msginfo_msgmni = 53 set msgsys:msginfo_msgtql = 14 Obviously, SEMMNS is the most important parameter. If you assume that each connection made to the database will generate 4 latches and if you assume that the database needs to support 1024 simultaneous connections, then you would need SEMMNS to be set to 4096. This value of 4096 should be considered a bare minimum Increase the kernel parameter SEMMNS if an ORA-7279 or ORA-27146 is generated. ORA-7251 If the latter case occurs, an ORA-7251 will be raised. Now Oracle begins allocating sets of size SEMMSL (or ORANSEMS, as the case may be) until it has at least PROCESSES semaphores. ORA-7252, ORA-733
