rfc1323, sb_max, tcp_sendspace, udp_sendspace, udp_recvspace報錯

OS：AIX 6100-07

ORACLE 11.2.0.2 RAC for aix安裝檢測不經過

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

經過my oracle support查詢到該問題是11.2.0.3下的bug,bug號爲：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

經過這樣link一下問題仍是不能解決。

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.

經過再次查詢，有這樣的解決方法：

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用戶下建：

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

再次檢查就經過了！
