Conclusion ,the following are the important parameters:

*project.max-shm-ids: Maximum shared memory IDs for a project. Replaces shmmni

*project.max-sem-ids: Maximum semaphore IDs for a project.Replaces semmni

*project.max-msg-ids: Maximum message queue IDs for a project. Replaces msgmni

*project.max-shm-memory: Total amount of shared memory allowed for a project. Replaces shmmax

*process.max-sem-nsems: Maximum number of semaphores allowed per semaphore set.Replaces semmsl

*process.max-sem-ops: Maximum number of semaphore operations allowed per semop.Replaces semopm

*process.max-msg-qbytes: Maximum number of bytes of messages on a message queue. Replaces msgmnb

*process.max-msg-messages: Maximum number of messages on a message queue.Replaces msgtql

    Hi
    I’m installing Oracle 10g on a Solaris 10 5/08 x86 and set the
    kernel parameters exactly as the manual said but but oracle installer says :

    Checking for shmsys:shminfo_shmmax=4294967295; found no entry. Failed <<<<
    Checking for shmsys:shminfo_shmmni=100; found no entry. Failed <<<<
    Checking for semsys:seminfo_semmni=100; found no entry. Failed <<<<
    Checking for semsys:seminfo_semmsl=256; found no entry. Failed <<<<
    Check complete. The overall result of this check is: Failed <<<<
    This is /etc/project file:
    system:0::::
    user.root:1::::
    noproject:2::::
    default:3::::
    group.staff:10::::
    oracle:100::::project.max-sem-ids=(priv,100,deny);project.max-sem-nsems=(priv,256,deny);project.max-shm-ids=(priv,100,deny);project.max-shm-memory=(priv,4294967296,deny)
    and project of oracle user is oracle.
    What should i do?
    Thanks

    do you add this parameter to your /etc/system
    shmsys:shminfo_shmmax=4294967295
    shmsys:shminfo_shmmni=100
    semsys:seminfo_semmni=100
    semsys:seminfo_semmsl=256

    and how much size your physical memory, cause this involved with the shmmax value.

    please tell men if not solve.
