HP-UX - Server maximum shared memory segments

The maximum shared memory segment size in all versions of Domino R5, up to and including 5.0.9, should not exceed the HP-UX system configuration assigned to the shmmax kernel parameter. To ensure that your settings comply with this requirement, set the shell environment variable Notes_SHARED_DPOOLSIZE below the value assigned to the kernel parameter shmmax. Alternatively, shmmax can be set to a value greater than 256Mb (for those systems that have the resources available), which will exceed the default size used by Domino (256Mb). An example setting for a system requiring a small shared segment size under 12 Mb would be assigned (using csh) as follows:

setenv Notes_SHARED_DPOOLSIZE 12000000
