RE: rootpre.sh

That is what Oracle is saying. That you need a 32-bit kernel extension to run 64bit Oracle.

David,

   I haven't installed Oracle 8.1.7 or 9.2 to AIX 5.1 yet, but thanks to a data storage interrupt kernel panic on a 5.1 box, I do know that 'crash' has been replaced by 'kdb' for examining crash dumps. So, rootpre.sh is going to break on the line   'PKEXT_PATH='echo le | crash | blah blah blah...'

I think the question is - do you need the post-wait kernel extension at AIX 5.1?  

I don't know about Oracle 8.1.7, but the 9.2 Installation Guide (p. 2-35) says: "For Oracle9i 9.2.0.1.0 on AIX 5L, the functon and performance benefits of the Oracle post-wait kernel extension are incorporated into the AIX kernel. Oracle 9i 9.2.0.1.0 on AIX 5L does not require the Oracle post-wait kernel extension to be loaded."  

(This begs the question as to whether I still would need to run rootpre.sh for asyncronous I/O configuration. Presumably, I could use smit to configure async I/O.)  

It seems to me I read somewhere that 8.1.7 still requires a 32-bit kernel extension and therefore, you may not be able to run a 64-bit AIX kernel with 8.1.7. Scott

I am trying to run rootpre.sh. My admin just upgrade the kernel to 64-bit. We were running 32-bit on this box and everything was fine. No Oracle software is running. I am going to install 64-bit 8.1.7 Ent Ed for AIX 5.1L when I got this trying to run rootpre.sh. This is what I get when I run:
#./rootpre.sh
