I can't believe you said "gay porn" in a post. Oh, wait, I can. Nevermind.

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

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

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 for boiling it down--you're right. Should be all down hill from here.

Indeed, he will dive in Iceland--I forgot about the order of things. I
wonder what other "firsts" he'll have in Iceland?!

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!

I never participated in that program, but I remember it. Sorry it got shut
down--seemed like a brilliant way to get customers (or prospective
customers) access to play with cool new stuff!

Re: TNS Listener Configuration for Oracle RAC

dannorris — 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

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.

I have no experiences related to SAP. Besides, after I wrote a whole blog post about how I don't like licensing issues, why would I want to write more about it?

Hi Martin,

I'm glad you posted as I was thinking of you specifically when I wrote this. Since I didn't get your contact information, I'd hoped you would be watching :). Thanks for the question and getting me thinking...

Re: Start Database Services automatically after instance startup

dannorris — Fri, 20 Mar 2009 23:02:29 -0000

I think it isn't recommended because there's no reliable way to do it. The -r physical_standby option wasn't really developed (apparently), so all CRS knows how to do is "startup open" and nothing else.

In 10g R2, I had good experiences with DG Broker--not sure about versions before then, but I can guess it may not have been so good back in V1 or V2 (DG was introduced in 9i, so that's basically V1 in my eyes).

Maybe I should have said that *I* don't know any better authority...at least not yet :).

Either way, with your consistent blogging on the topic, you're capturing a lot of the public's attention as the technical expert. I look forward to the session. Thanks for stopping by.

Re: Start Database Services automatically after instance startup

I got some feedback from one of my contacts (suffice it to say this is authoritative information). Basically, they said that they don't recommend using CRS to put the DB in standby mode. There is a "-r physical_standby" mode that was created, but not used, so avoid it. Instead, DG Broker is the recommended way to manage RAC standbys and it is documented too: http://download.oracle.com/docs/cd/B19306_01/se...

Hope that helps.

Hi Charles,

I haven't seen anything like that in the docs either. I don't think there's any way for CRS to handle it as the "agent" for RAC instances isn't extensible as far as I know. So, to offer this functionality, Clusterware development would have to get involved to support it (at least that's how I see it--not knowing how things are organized internally there).

Your question is a good one and I pinged a few friends that might have some more thoughts. If they don't post them here (assuming I get responses at all), I'll summarize and post results.

I'm not sure why you almost quoted Charles Schultz, but I'm guessing you're actually a bot. Hope this comment gets you the hits you're looking for. See Charles' comment at http://www.dannorris.com/2009/03/12/start-datab...

You're welcome. Nomination is a small part. The team that actually chooses recipients is pretty tough and thorough, so being approved/accepted is all on you and your work in the community. Glad to have you in the program!

My cluster is on 11gR1. Agreed, you could do an external callout from the DB to srvctl, but that seems like a lot of work when you ultimately do just the same thing that the clusterware callout script does :).

Re: Start Database Services automatically after instance startup

dannorris — Fri, 13 Mar 2009 23:41:35 -0000

I think it would (I didn't check and already shut down my cluster for the night). Not sure if CRS would ever determine that it is there, though. I doubt it.

Re: Start Database Services automatically after instance startup

dannorris — Fri, 13 Mar 2009 22:19:01 -0000

The script runs for any cluster event. The only ones it cares about are instance startup events. All other events are discarded and the script exits unless it sees INSTANCE as the first argument to the script (which is how the callouts pass the args).

I had to test your idea as I hadn't tried it yet. Unfortunately, DBMS_SERVICE doesn't actually change Oracle Clusterware's status. So, I don't think it'd be a complete solution. I also like the thought of placing one generic script in Oracle Clusterware and avoid maintaining a database startup trigger in each of the databases I have in the cluster (thinking of the case where there are 10+ databases in the RAC cluster).

Good idea--I didn't know until I tried that a database startup trigger fires each time a new instance opens the database. So, a two-node cluster would fire the trigger twice (once in each instance). That could mess things up if you didn't know about it ahead of time and could be a problem for those environments that are counting on having it fire exactly once at startup time. Glad you got me thinking enough to test that out!
