Too many Oracle kernel extensions on AIX ??

Hi everyone,

To all you kind Oracle folks, I'm an AIX sysdamin, not a DBA - hence the cross posting from comp.unix.aix.

One of my DBA colleagues is having problems with an Oracle 8.1.7.2 to 8.1.7.4 upgrade on a P690 LPAR running AIX 5.1, ML03.

Rooting around ( pun kind of intended ) I see that there appear to be FOUR "copies" - not sure what else to call them - of pw-syscall running.

Every piece of Oracle documentation that I've been able to find refers to loading an extension ( in the singular ).

Evidence ?

/etc/loadext -q /etc/pw-syscall

 Oracle Kernel Extension Loader for AIX

       Copyright (c) 1998,1999 Oracle Corporation

Extension /etc/pw-syscall found with kmid: 0x204cae4

So far, so good - just a single extension. But,

echo lke | kdb | grep pw-syscall returns:

1 05F5DD00 0204ABF8 00001024 00000273 /etc/pw-syscall
3 05F5D480 02049BC8 00001024 00000273 /etc/pw-syscall
5 05A26480 02048B98 00001024 00000273 /etc/pw-syscall
7 05A0BB00 02047B68 00001024 00000273 /etc/pw-syscall

Could this 1:4 relationship be responsible for (amongst other things):

>> ld: 0711-224 WARNING: Duplicate symbol: uiprrp
>> ld: 0711-224 WARNING: Duplicate symbol: uiprrc
>> ld: 0711-224 WARNING: Duplicate symbol: uiprrj
>> ld: 0711-224 WARNING: Duplicate symbol: uiprnp
>> ld: 0711-224 WARNING: Duplicate symbol: uiprgb

>> When relinking Oracle Financials on Oracle 8.1.7.2 on AIX 5

Other AIX boxes - running AIX 4.3.3 and 5.1 and Oracle 8 instances show a 1:1 relationship.

We have failed to remove these multiple extensions using both loadext -u and slibclean.

We do plan to reboot in the near future. We will disable the /etc/inittab entry and view the state of the kernel before and after a manual load of the extension [ not extensions ;-) ]

In the meantime, has anybody encountered this situation before ?

Is there another way to flush out these extensions if loadext -u and slibclean wont do it ?

Thanks in advance.

Nick.
