rfc1323, sb_max, tcp_sendspace, udp_sendspace, udp_recvspace报错

OS：AIX 6100-07

ORACLE 11.2.0.2 RAC for aix安装检测不经过

有rfc1323, sb_max, tcp_sendspace, udp_sendspace, udp_recvspace警告！

经过my oracle support查询到该问题是11.2.0.3下的bug,bug号为：bug 13077654

PRVE-0273 : The value of network parameter “udp_sendspace” for interface “en0″ is not configured to the expected value on node “racnode1″

bug 13077654 - AIX specific

On AIX, runInstaller complains network parameter setting: ipqmaxlen, rfc1323, sb_max, tcp_sendspace, udp_sendspace, udp_recvspace

INFO: *********************************************
INFO: Network parameter - rfc1323: Checks if the network parameter is set correctly on the system
INFO: Severity:IGNORABLE
INFO: OverallStatus:VERIFICATION_FAILED
INFO: ———————————————–
INFO: Verification Result for Node:racnode1

INFO: Error Message: PRVE-0273 : The value of network parameter “rfc1323″ for interface “en2″ is not configured to the expected value on node “racnode1″.[Expected="1"; Found="en2=0"]

Manually verified with “ifconfig” and “/usr/sbin/no”, the setting is as expected

This bug is fixed in 12.1 and onward

The workaround is to create a symbolic as root:

# ln -s /usr/sbin/no /etc/no

经过这样link一下问题仍是不能解决。

bug 13531373 - AIX specific

On AIX, runInstaller complains network parameter setting even when they are bigger than required:

INFO: *********************************************
INFO: Network parameter - tcp_sendspace: Checks if the network parameter is set correctly on the system
INFO: Severity:IGNORABLE
INFO: OverallStatus:VERIFICATION_FAILED
INFO: ———————————————–
INFO: Verification Result for Node:racnode1
INFO: Expected Value:1
INFO: Actual Value:en2=0
INFO: Error Message: PRVE-0273 : The value of network parameter “tcp_sendspace” for interface “en10″ is not configured to the expected value on node “racnode1″.[ Expected=" 65536"; Found="en10= 262144"]

As you can see, the expected value is 65536, and the current value is 262144 is satisfies the requirement.

The fix is included in 11.2.0.3 GI PSU2, 11.2.0.4 and above, the error can be ignored.

经过再次查询，有这样的解决方法：

1）修改：/etc/rc.net  添加以下：

if [ -f /usr/sbin/no ] ; then
/usr/sbin/no -p -o tcp_ephemeral_low=9000
/usr/sbin/no -p -o udp_ephemeral_low=9000
/usr/sbin/no -p -o tcp_ephemeral_high=65500
/usr/sbin/no -p -o udp_ephemeral_high=65500
/usr/sbin/no -p -o udp_sendspace=65536
/usr/sbin/no -p -o udp_recvspace=655360
/usr/sbin/no -p -o tcp_sendspace=65536
/usr/sbin/no -p -o tcp_recvspace=65536
/usr/sbin/no -p -o rfc1323=1
/usr/sbin/no -p -o sb_max=4194304
/usr/sbin/no -r -o ipqmaxlen=512
fi

2） root用户下建：

ln -s /usr/sbin/no /etc/no

再次检查就经过了！
