The set-flush BASIC program displays or changes the value of the period of the flush and of the forced flush.
Syntax
set-flush {{period}{,force.period}} {(options}
set-flush {{period}{,off}} {(options}
set-flush {{period}{,imm}} {(options}
Parameter(s)
|
period |
A new period (in seconds) with which the flush process wakes up automatically to write dirty (write-required) frames back to disk. The valid range is from 500 to 32000 milliseconds (0.5 to 32 seconds). If a period is not specified, the current flush period displays. The default period is defined at boot time by the flush statement in the configuration file. |
|
|
force.period |
New period (in seconds) with which the flush process wakes up automatically to write all buffers containing data belonging to the file system (item, indexes, and so on). This period is the guaranteed time after which an update to a protected file is written to disk. These values have a special meaning: |
|
|
0 |
All writes are done by the process itself. In other words, when a process updates an item, for example, the process waits until the write is completed. The keyword imm can be used to specify this option. |
|
|
-1 |
Forced flush mechanism is disabled. With this option, there is no guaranteed time for an update to the file system to be written to disk. The keyword off can be used to specify this option. |
|
|
options |
q |
Quiet mode suppresses all terminal output. |
|
NOTE— |
The default period is defined at boot time by the fflush statement in the configuration file. |
