Timers
hires_tick
- Description
When set, this parameter causes the Solaris OS to use a system clock rate of 1000 instead of the default value of 100. - Data Type
Signed integer - Default
0 - Range
0 (disabled) or 1 (enabled) - Dynamic?
No. Causes new system timing variable to be set at boot time. Not referenced after boot. - Validation
None - When to Change
When you want timeouts with a resolution of less than 10 milliseconds, and greater than or equal to 1 millisecond. - Commitment Level
Unstable
timer_max
- Description
Specifies the number of POSIXTM timers available. - Data Type
Signed integer - Default
32 - Range
0 to MAXINT - Dynamic?
No. Increasing the value can cause a system crash. - Validation
None - When to Change
When the default number of timers offered by the system is inadequate. Applications receive an EAGAIN error when executing timer_create system calls. - Commitment Level
Unstable
