I have seen some documents on kernel parms from oracle which i have found. I am trying to understand which underlaying kernel parms are used for oracle. I know the following parms are discussed by oracle but havent seen docs talk about maxdsiz or maxdsiz64 parms. What i am looking for is a doc that talks about oracle errors and its related kernel parm.

SHMMAX Maximum size of shared memory segment (bytes) 250kB + 8.2kB * shared_buffers + 14.2kB * max_connections or infinity
SHMMIN Minimum size of shared memory segment (bytes) 1
SHMALL Total amount of shared memory available (bytes or pages) if bytes, same as SHMMAX; if pages, ceil(SHMMAX/PAGE_SIZE)
SHMSEG Maximum number of shared memory segments per process only 1 segment is needed, but the default is much higher
SHMMNI Maximum number of shared memory segments system-wide like SHMSEG plus room for other applications
SEMMNI Maximum number of semaphore identifiers (i.e., sets) >= ceil(max_connections / 16)
SEMMNS Maximum number of semaphores system-wide ceil(max_connections / 16) * 17 + room for other applications
SEMMSL Maximum number of semaphores per set >= 17
SEMMAP Number of entries in semaphore map see text
SEMVMX Maximum value of semaphore
