Re: TNS Listener Configuration for Oracle RAC

Admittedly this is rather late, but you should be sure and use the fqdn when using a name rather than ip for the remote and local listeners. There is an oracle bug referencing this. What it amounts to is that if you dont use the fqdn for the local listener, when you connect to the database from a different default domain, the oracle client will have trouble connecting if the local listener setting doesnt include an fqdn.

Oracle Blog Contacting — Thu, 14 Jul 2011 13:04:38 -0000

Hello Dan,

please take first my apologies for contacting you as owner of the Dannorris.com blog. As Oracle database professional you will be familiar
with the advantages/disadvantages of Oracle tracefile analysis. So there is no
need to waste your time with long explanations.

The company I work for is developing a tool
named QueryAdvisor specialized on Oracle tracefile analysis. QueryAdvisor
provides more information and allows easier access to tracefile data then
TKPROF (alone or in combination with TRCSESS) or even TRCANLZR does.

We are now looking for DBAs and developers
assisting as betatesters. We have chosen this approach to be sure that we will
cover a huge amount of different Oracle database configurations (different
hardware / releases / patch levels).

You will receive a free Administrator License
without restrictions or further obligations for your participation in our
betatest and/or writing an article. To avoid any misunderstanding - this is not
a new approach to sell you something. We are talking about a free license in
exchange of some of your time and experience - nothing more nothing less. We
hope that this is a win win situation for both of us.

You will find additional information and the
possibility to register as betatester at:

http://goo.gl/akWSL

More information how to obtain a free license
for writing an article and/or review is available at: http://goo.gl/W2LpF

If you like to do us a special favor - talk to
your colleagues about our betatest and share the link.

We will take care that you will not be
contacted a second time. Sorry for any inconvenience caused and thanks for your
time.

Kind regards

Frank

Re: Cloning a VM on ESX Server 3.0.1

Thanks, this worked perfectly. It is perplexing that they wouldn't add the clone VM feature in the free version of ESX. Either way, I will just script up this process and call it a day. Thanks again.

Dan,

Thanks for ur reply .. I also want to compress or gzip the rotated logs .. It will be great if u can help me on that .....

Thanks Again !

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.

Thank you so much for this post. You have no idea how much you have helped me today by sharing this little tidbit. Our Oracle App Server was also crashing periodically for no apparent reason and now we know why! I implemented the changes indicated in the Metalink note and it seems to work! Thanks again!!

Re: TNS Listener Configuration for Oracle RAC

Dan Norris — Fri, 04 Mar 2011 16:57:56 -0000

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.

Re: TNS Listener Configuration for Oracle RAC

Steve — Fri, 04 Mar 2011 16:31:34 -0000

Hi Dan, Nice post!

Have couple of questions in reading your post. Most of our implementations at customer sites are done with DB in cold failover mode where we have DB vlan which only App nodes can talk to and OAM vlan or control vlan where back office application can only talk to. In these cases, we generally have the listener endpoints to listen on both DB VIP and OAM VIP and they fail over to other node in the cluster, if primary node fails for some reason. All works great. However, if we had to support RAC with similar support i.e having back office apps connect to DB via control vlan only, what would you recommended setup?

And how does this work with SCAN listeners on RAC?

Cold failover protected by 11gr2 Oracle Clusterware is even worse cause during failover, we fail just the DB and not SCANs or restart local listeners. In a typical cold failover solution, we failover db,listener and storage resources along with it, but with clusterware, we have asm clustered but DB running in cold failover mode.

Appreciate your feedback.

Re: Portal Virtual Host Configuration

Dan Norris — Fri, 11 Feb 2011 09:20:59 -0000

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.

Fantastic works a treat.
However, when I go to the URL (e.g. www.dan.com) and try and login the URL for SSO login is redirected to (using your server names) http://nap01.itconvergence.com:7777/sso/jsp/login.jsp rather than http://www.dan.com. How do I change that?

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.

Hey Dan. This is Jake Ramirez in Vancouver WA. Wanted to know if I could call you about Cluster Listener config in 11gR2. Also need to talk to you about one more thing :)

Re: Concatenating lines in ldapsearch results

Asier Larrabide — Mon, 04 Oct 2010 04:21:34 -0000

Many thanks for this post. There's a little problem with this solution. If the ldif is very big the array could collapse the memory. In my case the ldif allocates 70 gb os disk space, so the script with the array crash.

In this case I would prefer this script:

#!/usr/bin/perl

while ($line = <>) {
chomp($line);
if ( $line =~ /^authpassword/ ) {
next;
} elsif ( $line =~ /^\S+/) { ### this line is a "normal" or starting line
print "$complete_line\n";
$complete_line=$line;
} elsif ( $line =~ /^$/ ) { ### this line is blank
print "$complete_line\n";
$complete_line="";
} elsif ( $line =~ /^\s+(\S.*)/ ) { ### this line is a continuation
$line =~ s/^\s+//;
$complete_line=$complete_line . $line;
}
}

This script can be run in a pipe, like this:

# gzcat backup_ldif.gz | ./concat_ldif.pl
