SHMMAX mean: This setting does not decide how much physical memory is used in Oracle database or operating system, only determines the number of memory available. This setting does not affect the kernel resources of the operating system. Setting method: 0.5 * Physical memory example: SHMINFO_SHMMAX = 10485760 shmmin meaning: Shared memory minimum size. Setting method: Usually set to 1. Example: set shmsys: shminfo_shmmin = 1: SHMMNI meaning: The maximum number of memory segments in the system. Example: set shmsys: shminfo_shmmni = 100 shmseg Meaning: The number of maximum shared memory segments per user process can be used. Example: set shmsys: shminfo_shmseg = 20: semmni meaning: The maximum number of Semaphore Identifierer in the system. Setting method: Set the value of this variable to all Oracle's instances of all Oracle's instances of the processes to add 10. Example: Set Semsys: seminfo_semmni = 100 SemMns Emnity: The maximum number of EMAPHORES in the system. Setting method: This value can be calculated in the following manner: the sum of the value of the processes of each Oracle instance, the sum of the value (remove the largest processes parameter) the number of the maximum of the processes × 2 10 × Oracle instance. Example: Set Semsys: seminfo_semmns = 200 Semmsl Meaning: The maximum number of Semaphore in a set.
