Hello,
On Aix 5.2, we changed the parameters tcp_keepinit, tcp_keepintvl and tcp_keepidle with the no command.
tunrestore -R is present in inittab
in the directory /etc/tunables we can clearly see the inclusion of parameters during reboot, including the file lastboot.log
root#/etc/tunables#ls -ltr
total 40
-rw-r--r-- 1 root system 493 Nov 5 17:38 nextboot
-rw-r--r-- 1 root system 334 Dec 3 17:39 lastboot.log
-rw-r--r-- 1 root system 11735 Dec 3 17:39 lastboot
root#/etc/tunables#grep keep nextboot
tcp_keepinit = "40"
tcp_keepintvl = "20"
tcp_keepidle = "600"
root#/etc/tunables#grep keep lastboot.log
Setting tcp_keepidle to 600
Setting tcp_keepinit to 40
Setting tcp_keepintvl to 20
root#/etc/tunables#grep keep lastboot
ndpt_keep = "120" # DEFAULT VALUE
tcp_keepcnt = "8" # DEFAULT VALUE
tcp_keepidle = "600"
tcp_keepinit = "40"
tcp_keepintvl = "20"
But when we checked with the no command, the parameters are not valid
root#/etc/tunables#no -L | grep keep |grep -v cnt |grep -v ndpt
tcp_keepidle 6840 14400 600 1 8E-1 halfsecond C
tcp_keepinit 40 150 40 1 8E-1 halfsecond D
tcp_keepintvl 110 150 20 1 32K-1 halfsecond C
root#/etc/tunables#no -a | grep keep |grep -v cnt |grep -v ndpt
tcp_keepidle = 6840
tcp_keepinit = 40
tcp_keepintvl = 110
is it because of the pre520tune parameter is disabled?
root#/etc/tunables#lsattr -E -l sys0 |grep pre520
pre520tune disable Pre-520 tuning compatibility mode
True
have you a solution for this problem?
thank you for your answers
