Operating Systems Solaris Kernel Parameters in Solaris 10 Post 302132577 by pressy on Friday 17th of August 2007 12:33:04 PM

FYI:
The Solaris 10 Operating System introduces the following new resource controls to replace the old /etc/system tunables:
Code:
                              Old             Old       New         New
    Resource control          tunable         default   Max value   default
    ----------------------    -------------   -------   ---------   ----------
    process.max-msg-qbytes    msginfo_msgmnb  4096      ULONG_MAX   65536
    process.max-msg-messages  msginfo_msgtql  40        UINT_MAX    8192
    process.max-sem-ops       seminfo_semopm  10        INT_MAX     512
    process.max-sem-nsems     seminfo_semmsl  25        SHRT_MAX    512
    project.max-shm-memory    shminfo_shmmax  0x800000  UINT64_MAX  1/4 physmem
    project.max-shm-ids       shminfo_shmmni  100       2**24       128
    project.max-msg-ids       msginfo_msgmni  50        2**24       128
    project.max-sem-ids       seminfo_semmni  10        2**24       128

As the names suggest, these rctls are attributes of either processes or projects.

The following tunables are now obsolete in the Solaris 10 Operating System:
Code:
    Shared Memory        Semaphores             Message-Queue
    --------------       --------------         ---------------
    shminfo_shmseg       seminfo_semmns         msginfo_msgmax 
    shminfo_shmmin       seminfo_semvmx         msginfo_msgssz 
    shminfo_shmmax*      seminfo_semmnu         msginfo_msgmni*
    shminfo_shmmni*      seminfo_semaem         msginfo_msgtql*
                         seminfo_semume         msginfo_msgmnb*
                         seminfo_semusz         msginfo_msgmap
                         seminfo_semmap         msginfo_msgseg
                         seminfo_semmsl*
                         seminfo_semopm*
                         seminfo_semmni*


   values ending in * are technically obsolete, but if they are present
   in the /etc/system file then at boot the kernel will translate the
   values into global resource controls.

1.-Is there a way to find out the current parameter values in SOLARIS 10, so that I can compare the current parameter values that I have from the old solaris 8.
have a look at: "prctl $$"
