#### Solaris

In Solaris 9, because of the kernel changes, the `hmsys:shminfo_shmseg` variable is obsolete. In Solaris 8, add the following settings to the `/etc/system` file:

    set shmsys:shminfo_shmmax = 0xffffffff
    set shmsys:shminfo_shmseg = <default=6>
    set shmsys:shminfo_shmmni = <default=100> + (6 * NNODES)

Default values are for Solaris 8. Add HADB resource requirements to the previous value of the variables regardless of whether they are the default values.

Note –

You must reboot the host after changing these settings.
