Re: [U2] UniData Upgrade
Thanks Wally! I saw your post but things are crazy for me today and my typing got ahead of my thinking (too many fires, not enough water buckets). I have passed your info on to the folks here.

RE: [U2] UniData Upgrade on AIX
We did a similar upgrade not too long ago and these are the only notes I have from it: In @udthome/sys/UDTSPOOL.CONFIG the nhead option needs to be set to U_IGNORE instead of -o to stop it from using -o nobanner You can enter SETPTR 0 to see which options it is using. However, we use SB+ which pretty much eliminates the need to use setptr so this may not be a surprise for you Colin Alfke Support Specialist Thomson Elite 450, 800 - 6th Ave. S.W.

[U2] UniData Upgrade on AIX
I am going to upgrade an IBM RS/6000 with AIX 4.2.2 and UniData 5.1 to AIX 5.2.3 with UniData 6.0.8. While I have upgraded to UniData 6.0.X on AIX before, it has only been on AIX 4.3.3. I do know that AIX needs to be upgraded first to 4.3.3 and then to 5.2.3, however, I don't know if I need to be concerned with anything else. Any issues I may need to address? Is there anything significantly different with AIX 5.2.3 that needs more attention? Thanks.
