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.
