All devices on AIX have attributes associated with them. To view device attributes, enter:
lsattr -E -l DeviceName
Any attributes with the value True can be modified with the command:
chdev -l DeviceName -a attr=value
Attention: Changing device parameters incorrectly can damage your system.
By default, the maximum number of processes per user is 40. The default value may be too low for users who have many windows open simultaneously. The following command can be used to change the value systemwide:
hdev -l sys0 -a maxuproc=100
This example changes the maximum number to 100. The new value is set once the system has rebooted.
To view the current setting of this and other system attributes type:
lsattr -E -l sys0
The maxmbuf attribute is not currently supported by the mbuf services.
AIX supports the vmstat and iostat commands, but not the systat command or load averages.
