DBA is asking for Kernel Extension Version: 3 we have version 2.

How do I do this?

Thanks
 
I'm not sure what the DBA is asking for: what does it mean kernel extension? AIX has version, release, maintenance (like 4.3.3). Is the DBA referring to the database software that needs a "kernel extension"?
 
I have 2 AIX machines one with Kernel extention version 2 and one with Kernel extention version 3. The DBA does not have issues with the latter but says we need to bring the other one up with Kernel extention version 3? Can I get this off of the installation CD's?

Thanks
 
What does kernel extension mean?
 
Is this Oracle? The kernel extensions and loader are installed by running the rootpre.sh script which is located in the orainst directory. This script will install the kernel extensions (ora_kstat & pw-syscall) and loader (loadext) into /etc and will also make the required entries to /etc/inittab to ensure these are loaded on reboot.

Note, the script will also activate async/io but will not change the default values.

When they do that it loads version 2 of the kernel and they need version 3 for Oracle 8i. Do I get this off of the AIX installation CD's?
 
Following is the command I use to check the version:

root@/>/etc/loadext -r

Oracle Kernel Extension Loader for AIX
Copyright (c) 1998, Oracle Corporation

> > Currently running Kernel Extension Path: /etc/pw-syscall
Kernel Extension Version: 2

root@/>

What do I need to install for version 3? I can not find anything in the AIX doc about this.

Thanks
 
This is an Oracle thing. Sounds like you might need to upgrade Oracle so the two systems are running the same version of the software? (Perhaps your DBA needs to be a little clearer and less database-techie in asking for what he/she wants?) If it is an upgrade that is needed, I strongly suggest you either let the DBA do it, or work very, very closely with the DBA on the planning and execution.

What version of Oracle are you running on both systems?
 
awilco - No this is not from the AIX installation CDs, it's from the Oracle installation CDs.

When I check my systems via loadext the result is:
loadext -r

Oracle Kernel Extension Loader for AIX
Copyright (c) 1998,1999 Oracle Corporation

> >
Currently running Kernel Extension Path: /etc/ora_kstat
Kernel Extension Version: 2

Currently running Kernel Extension Path: /etc/pw-syscall
Kernel Extension Version: 3

Looks like I have a different version of loadext to you:
sum /etc/loadext
05166 12 /etc/loadext
ls -l /etc/loadext
-r-x------ 1 root system 11947 Nov 27 2001 /etc/loadext

I suggest you regenerate the orainst directory from the Oracle CDs, and try rerunning rootpre.sh.
 
Sectorseveng is correct. Version 3 of the kernel would not load because there was another Oracle SID running with V2. It checks to see if another version is running and will not load on top. Version 3 loaded fine, from the Oracle CD, once all SIDS were shut down.

Please, thank you all for your replies.
