2.105 query_buffer_availability
The query_buffer_availability command returns information about the amount of STREAMS buffer space
that SNAplus2 is currently using, the maximum amount it has used, and the maximum amount available (specified
using the set_buffer_availability command). This information enables you to check STREAMS buffer
usage and set the limit appropriately to ensure that sufficient buffer space is available for SNAplus2 components
and for other programs on the HP-UX computer. The command also returns additional internal values related to
buffer usage for use by SNAplus2 support personnel.
2.105.1 Supplied Parameters
Parameter name Type Length Default
[query_buffer_availability]
reset_max_values constant NO
Supplied parameter is:
reset_max_values
Specify whether SNAplus2 should reset the max_* values (after returning them on this command) to match
the current values of these parameters. This ensures that a subsequent query_buffer_availability
command will return the maximum values reached since this command was issued, rather than the maximum
values reached since the system was started (or since the max_* values were last reset). Possible values are:
YES
Reset the max_* values to match the current values.
NO
Do not reset the max_* values.
