    Unanswered: Class "M" in onstat -g seg ?

    Hi,

    Here is the output for onstat -g seg. What I want to know is why are there 3 entries for "M" type.

    (* segment locked in memory)


    The Shared memory parameters on onconfig file are:

    SHMBASE 0x0 # Shared memory base address
    #SHMVIRTSIZE 120000 # initial virtual shared memory segment size
    # Modified the SHMVIRTSIZE on 7.12.04 (Nitin Mathur)
    SHMVIRTSIZE 180000 # initial virtual shared memory segment size
    SHMADD 16384 # Size of new shared memory segments (Kbytes)
    SHMTOTAL 0 # Total shared memory (Kbytes). 0=>unlimited
    LRUS 120 # Number of LRU queues
    LRU_MAX_DIRTY 2 # LRU percent dirty begin cleaning limit
    LRU_MIN_DIRTY 1 # LRU percent dirty end cleaning limit
    BUFFERS 180000 # Maximum number of shared buffers
    CLEANERS 24 # Number of buffer cleaner processes


    Thanks in advance.

    Hi Gustavo,

    Thanks for the answer. But since there are 3 entries for class "M" is it coz of the following parameter in onconfig:

    NETTYPE ipcshm,3,600,NET # Configure poll thread(s) for nettype
    NETTYPE soctcp,3,600,CPU # Configure poll thread(s) for nettype


    Bye

    Hi,

    Exactly, the 3 in NETTYPE correspond to connection for ipc.

    Gustavo.
