The following settings are recommended:
set msgsys:msginfo_msgmax = 65535 Maximum size of System V message.
set msgsys:msginfo_msgmnb = 65535 Maximum number of bytes that can be on any
one message queue.
set msgsys:msginfo_msgssz = 32 Specifies size of chunks system uses to
manage space for message buffers.
Obsolete since the Solaris 8 release.
set msgsys:msginfo_msgseg = 16384 Number of msginfo_msgssz segments the system
uses as a pool for available message memory.
Total memory available for messages is
msginfo_msgseg * msginfo_msgssz.
Obsolete since the Solaris 8 release.
set semsys:seminfo_semmni = 4096 Maximum number of semaphore identifiers.
set msgsys:msginfo_msgtql = 10000 The maximum number of queue entries that
can be in the system at the same time.
A low value can adversely affect
system performance, or cause the
client to freeze. IBM® recommends that
you set this value to the maximum (10000),
or at least double the maximum number of
concurrent requests. Stress load your
system, and then use the ipcs -qa command
to determine the setting.
Set these values by changing the entries in the /etc/system file. See Solaris system notes for information on changing this file.
