Re: Why Do an Inflight Mag Check?

Dan Norris — Wed, 29 Oct 2025 12:48:30 -0000

We had a case where runup mag check was fine, but in cruise one cyl was only firing on one mag. Root cause turned out to be a bad wire. We overhauled mags and all cylinders, so it's likely that the cables were moved more than usual and that would expose any issue with cable fatigue. Replaced all cables and issue cleared (after replacing spark plugs, etc).

Thanks for the note Randy. There are always two sides to the story as I think there may be here. For the Nautilus viewpoint, please see this link: https://nautilusliveaboards...

The ErrorLog directive shown in the post is the actual parameter. Check your httpd.conf and you'll see an ErrorLog directive. Replace it with something like what I've shown above if you'd like.

Re: TNS Listener Configuration for Oracle RAC

For 11gR2, all the stuff above is automatically configured when the DB is started. No manual configuration needed for any of it. However, some of the status commands are helpful for troubleshooting and debugging.

There's exactly one SCAN allowed, so if your database server has more than one interface used for client connections, one can use the SCAN, the other will have to use the pre-11.2 method that lists all the VIPs (which you'll have/want to create too).

I have no experience with the cold failover, but if you use RAC One, it is mostly automated.

I'd double-check the NameVirtualHost setting, but honestly this article is
more than 2.5 years old and I don't work on OAS much these days, so I'm not
sure I have too much debugging help to provide anymore.

please share.

Let's keep the Q&A on listener issues here for all to benefit.

Shoot me a mail on whatever else you need - my schedule is tight for the
next 2 weeks, so a call is probably less likely to get answered than an
email.

Re: Oracle 11g dbhome broken…oh, wait, nevermind.

I don't know of a command that displays running instances. I usually use "ps -ef|grep smo", similar to what you posted. I don't think it's that difficult to type and if it is that bothersome, then the first thing to type is "alias i='ps -ef|grep smon'" so that it's readily accessible. I also typically keep a text file of all the frequent commands handy for easy copy/paste which may also solve your issue.

Re: My iPhone Dilemma

Interesting to note that your disdain for umbrellas has now cost you real money in addition to the medical bills for all the poked eyes you've endured.

I certainly feel for you and think you're smart to stick with the platform. I agree that the new devices look really cool, but I think I'll probably be an iPhone user for a long time too.

I use the over-the-air sync on my phone, but I suspect that was a feature of the 3G phone that your current model probably doesn't have, so that won't help. I guess you could just sync things with Google and use their app for accessing info about contacts, etc. That way you could maybe limp along until the update comes, whenever that may be.

I'll be interested to know which path you take. Given the rumors about a break from AT&T, starting another 2-year sentence would be a non-starter for me.

Re: Email Address Matters

Dan Norris — Mon, 11 Jan 2010 22:09:25 -0000

I completely agree and AOL is pretty close to the bottom of my list too. I think I mentally give -0.5 points for hotmail.com these days, not sure why except its current affiliation with M$. I went from my college email to yahoo.com and then to my own personal domain name and have been there ever since (moving it to a few different hosting providers along the way).

Unlike many, I only use the one account and don't have a "spam only" account anywhere. I do keep my yahoo.com account around as an alternate just for the place that hosts my personal domain (where else would I have them email me if I log a ticket that my email is broken?).

I think I also give a little +1 to those that use a personal domain on resumes. Oh, I also have a friend that still uses netzero.net as their primary email account--betcha most people don't remember that org either!

Re: Configuring Multiple Weblogic IIS Plug-Ins On Same IIS Server

Dan Norris — Mon, 11 Jan 2010 09:18:13 -0000

I don't recall the pathname, sorry. However, do know that this was done over 18 months ago, so the version you're using now may have an alternate mechansim for interconnecting with IIS than the version used for this article.

Re: So, What Do You Do?

Dan Norris — Fri, 20 Nov 2009 15:42:01 -0000

I typically make mention of my very short attention span and if I haven't seen a shiny object go by yet and am still focused on the conversation, I explain that my job involves lots of different types of tasks. Some days I help customers fix broken stuff, other days I research to find ways to do things better, and occasionally, I get to spend time giving training or presenting a session at a conference.

I always worry that if I don't try to explain it, I'll sound insulting--as though they couldn't possibly understand it. And if I over-explain it, they really won't understand it. It's a thin line...to satisfy requires you to take into account the audience and often, their mood or demeanor.

Re: Configuring Multiple Weblogic IIS Plug-Ins On Same IIS Server

Dan Norris — Fri, 26 Jun 2009 09:13:48 -0000

I don't think I understand the question. Depending on how your network and DNS records are configured, users on the internet and intranet should have equal and same access to the environment.

The ORACLE_HOME throughout the process remains the middle tier (Portal) O_H--you never switch to use the INFRA O_H during this process as outlined in the post.

Re: New job, lots of exciting stuff

Dan Norris — Tue, 23 Jun 2009 15:26:30 -0000

Thanks, Kyle. I had the VPN installed too, just too many other things that I
felt it better to conform with the corporate standard for now. I don't
anticipate it will be too long to go back to the Mac--I miss it a lot
already.

I knew before I joined that there is a lot of MacOS in use at Oracle. I just
reverted to Windows long enough to make sure I have all the necessary
software components. I hope to go back to Mac soon.

Thanks for the heads up!

Thanks Charles and Simon.

Charles: you're right about Rac attack and JS was reading over my
shoulder when I saw your comment, so he knows the same.

Simon: I would love to--hopefully there are some Exadata customers
that will encourage my presence at ukoug and other UK events!

Re: TNS Listener Configuration for Oracle RAC

Dan Norris — Sat, 11 Apr 2009 06:53:13 -0000

A few ideas come to mind. To answer your question, you could use a tns
entry that references all instances/servers to check overall
availability and also separately check each individual instance to
determine availability.

You might also consider using clusterware callouts to alert you.
Scripts placed in ora_crs_home/racg/usrco will be run whenever
clusterware detects a resource offline. That may be easier than
writing your own custom polling method.

Re: Requiem for the Computer Lab

Dan Norris — Mon, 30 Mar 2009 21:28:46 -0000

I distinctly remember downloading slackware linux onto something like 15 3.5" floppies using a 28.8kbps modem over the course of a day or two (partly due to dropped connections). Before starting the download, I had to make room for the downloads on my hard drive (it might have been 200Mb or so...maybe less).

I also remember using "talk" and "ntalk" to chat with friends online.

Ahh...the good ol' days. Sad that my kids don't know what cassette tapes or VHS tapes are, let alone a world before computers when having an Apple IIgs with 1Mb of RAM meant you were *rich*.

And good tip on PCU--I loved that movie. I think that was the first one I remember with Jeremy Piven and I was a fan from then on.
