This is why we need to be more careful about what we tell users

A thought for a Sunday morning.

This is a bit old, but nonetheless nails home a serious point about user awareness.

Technote on broken streaming cluster replication issue in R8 gets new information

Andy Pedisich  August 14 2008 08:53:17 AM

I originally picked up on Technote 1304671  back on July 1st, 2008 while preparing to speak at the San Franciso ND8 Upgrade Seminar for The View.  I found it to be a bit disturbing.  I was thinking, "How the heck do you know you're having this problem in the first place?"  And yes, I do sometimes save Technotes in my journal so they'll be readily accessible for clients.

Well, the Technote was modified again on August 4th, and included this new piece of information to help you determine if you're got the streaming replication heebie jeebies.

In addition, you may also receive the following error:

"ClientSCR: Error reading SCR object: RRV=xxxx Error-Invalid or nonexistent document"

If you're as nervous about this as I am, you can turn streaming replication off as pointed out in the article.

If you want to disable SCR completely and use regular clustered replication, do the following:

1. Add the following debug parameter in your notes.ini file:
  DEBUG_SCR_DISABLED=1 (must be implemented on all cluster mates)
2. Clear the replication history.

Also, I think that the DEBUG_SCR=128 is a bit heavy handed and will pretty much flood what you're watching.  127 seems to do the trick just fine.

While the Technote does make me uncomfortable, it also is an indication that the problem is being worked on.  I'll bet a dollar that the problem won't be around in future versions of Domino and that a fix is on the way.  It's too much of a desirable core feature for IBM/Lotus to let sit this way.

Meantime, perhaps you should just turn the thing off until we get more information.

An evening with Radiohead

Andy Pedisich  August 13 2008 09:53:59 AM

We left the house for the sold out Radiohead show without tickets.  Linda was confident her Craig's List connection would come through for 2 lawn seats, and she was pretty sure we could score another on the cheap.  Mission accomplished.  But traffic and ticket scoring cut into our time, so we missed the first act completely.  We did have plenty of time to settle in for Radiohead, however.

I think I have a bit of whiplash because the show was such a 180 degree turn from last night's King Crimson performance.  And even though the venue was an arena rather than a theater, I think that the sound was so much more superior.  

Radiohead had me in their clutches right at the second song, There There (The Boney King of Nowhere).

This was my first time seeing Radiohead, and they are an extremely innovative band.  I found them to be much more accessible in a live context than in a recorded studio setting. And what I heard and saw will make me backtrack over their stuff now that I have a better understanding of the nuances of their material.

I took no pictures of the lighting that would do them justice. Most times, bands use spots to highlight the musicians.  While Radiohead performed, the lights were mega, total stage paintings, with almost no spots at all on the players.  You were drawn into to the hypnotics of the music and the total effect of the illumination.

Lead singer Thom Yorke's vocal renderings were carefully woven into the band's often minimalistic arrangements, and his voice was at once plaintive and prayerful  The music was tightly conceptual and always well calculated, creating a column of sound that would bear down on your senses.

It wasn't until I sat on the lawn and closed my eyes to listed that I realized how concentrated and truly beautiful their sound was.  Lights and visual presentation, while excellent and abstract, were really unnecessary.

See them if you can.  But try not to wait until the last minute to get tickets.  You might miss the opening act.
