Hello Listers,
On all nodes of a RAC database, oifcfg iflist takes 2 minutes to report the
results.
CRS version: 11.1.0.7, Platform: IBM AIX 6.1
/etc/hosts has all the IPs reported by the output of iflist command.
'netstat -in' also reports all the interfaces available at the OS level.
Truss with -d and -f switch gives following:
1421608: 1155345: kread(0, " l i d : V L A".., 4096) = 2281
1421608: 1155345: kread(0, " l i d : V L A".., 4096) = 0
1421608: 1155345: kwrite(1, " H a r d w a r e A d d".., 36) = 36
308104: kread(9, " H a r d w a r e A d d".., 4096) = 36
1421608: 1155345: *126.7475*: close(1) = 0
1421608: 1155345: 126.7478: kfcntl(2, F_GETFL, 0x00000001) =
67110914
308104: 126.7478: close(9) = 0
1421608: 1155345: 126.7479: _exit(0)
Without -f switch in the truss command, I see the following:
0.3459: kfork() = 258936
0.3484: thread_setmystate(0x0FFFFFFFFFFFD5F0, 0x0000000000000000) = 0
0.3487: close(10) = 0
0.3489: kfcntl(9, F_GETFL, 0x0000000110007DD0) = 0
0.3490: kioctl(9, 22528, 0x0000000000000000, 0x0000000000000000)
Err#25 ENOTTY
0.3509: kioctl(9, 22528, 0x0000000000000000, 0x0000000000000000)
Err#25 ENOTTY
2.3512: kread(9, "\0\0\0\0\0\0\0\0\0\0\0\0".., 4096) (sleeping...)
kread(9, " H a r d w a r e A d d".., 4096) = 36
*117.3814*: close(9) = 0
On a different RAC cluster in same network, same command reports results
within a Second as expected.
1286398: 3903619: 0.5246: kioctl(0, 22528, 0x00000000,
0x00000000) Err#25 ENOTTY
1286398: 3903619: kread(0, " - - - - - - - - - - - -".., 4096) = 2626
1286398: 3903619: 0.5250: kioctl(1, 22528, 0x00000000,
0x00000000) Err#25 ENOTTY
1286398: 3903619: kread(0, " - - - - - - - - - - - -".., 4096) = 0
1286398: 3903619: kwrite(1, " H a r d w a r e A d d".., 36) = 36
1286398: 3903619: *0.5255*: close(1) = 0
1347678: 2179287: kread(9, " H a r d w a r e A d d".., 4096) = 36
1286398: 3903619: *0.5257*: kfcntl(2, F_GETFL, 0x00000001) =
67110914
1286398: 3903619: 0.5258: _exit(0)
1347678: 2179287: 0.5258: close(9) = 0
Any hints/suggestions are welcome..
Note: oifcfg getif reports the results in a second.
