Tuning Virtual Memory Manager (VMM)

Oracle recommends that you use the vmo command to tune virtual memory.

Note:

• The lru_file_repage parameter does not apply to IBM AIX 7.1 and later updates to IBM AIX 7.1.
• The tunable parameters strict_maxclient and strict_maxpermare deprecated in IBM AIX 7.2 and later updates to IBM AIX 7.2.

Table 3-5 Recommended Values for Virtual Memory Manager

Parameter	Value
minperm%	3
maxperm%	90
maxclient% = 90	90

For example:

vmo -p -o minperm%=3
vmo -p -o maxperm%=90
vmo -p -o maxclient%=90

You must restart the system for these changes to take effect.
