System V Message Parameters
msgsys:msginfo_msgssz
| Description | Specifies size of chunks
system uses to manage space for message buffers. Obsolete since the Solaris
8 release.
|
| Data Type | Signed integer
|
| Default | 40
|
| Range | 0 to MAXINT
|
| Dynamic? | No. Loaded into msgtql field of msginfo structure.
|
| Validation | The space consumed by
the maximum number of data structures that would be created to support the
messages and queues is compared to 25% of the available kernel memory at the
time the module is loaded. If the number is too big, the message queue module
refuses to load and the facility is unavailable. This computation does include
the space that might be consumed by the messages. This situation occurs only
when the module is first loaded.
|
| When to Change | When the default
value is not enough. Generally changed at the recommendation of software vendors.
|
| Commitment Level | Obsolete
|
msgsys:msginfo_msgmap
| Description | Number of messages the
system supports. Obsolete since the Solaris 8 release.
|
| Data Type | Signed integer
|
| Default | 100

msgsys:msginfo_msgseg
| Description | Number of msginfo_msgssz segments the system uses as a pool for available

* msginfo_msgssz. Obsolete as of the Solaris 8 release.
|
| Data Type | Signed short

| Default | 1024
|
| Range | 0 to 32,767
