			<content:encoded><![CDATA[<p>Hello Oracle fans and victims out there,</p>
<p>I tried to create a 10.2.0.5 database on top of an existing 11.2.0.3 GI (with an already fine running 11.2.0.3 RDBMS as second database), 2 node RAC.</p>
<p>Installed the 10.2.0.1 + 10.2.0.5 PS + 10.2.0.5.6 PSU&#8230; worked like a charm.</p>
<p>After pinning the nodes (<em>remember, you have to do that for a pre-11gR2 database on 11gR2 Clusterware!</em>), I created the RAC database with DBCA&#8230; worked like a charm.</p>
<p>I started up the database with srvctl &#8211; crash. Both instances were killed by their LMON because of a KGXGN polling error. It looks like this in the alert logs:</p>
<p>Instance #1:</p>

<p>The LMON trace files just revealed the same information for me. I installed the 10.2.0.5.2 CRS Bundle into this ORACLE_HOME &#8211; no change. The internet &#8211; including MOS &#8211; gave hints in many directions, but nothing really seemed to match.</p>
<p><strong>Finally, after a day off (you sometimes need distance!) I got it:</strong></p>
<p>The error messages highly indicate an interconnect problem. The fact that a second (11gR2) database works fine at the same time excludes physics and other problems on the base of the stack. The server and the 11gR2 world has 2 interconnect interfaces. Solution: I just burned the IP of one specific interconnect interface into the init.ora parameters of the 10gR2 instance &#8211; and we got a take off. It works like a charm.</p>

			<content:encoded><![CDATA[<p>Hi there,</p>
<p>I was analyzing some unexpected RMAN termination, a RMAN-10038/RMAN-03009 combo:</p>
<pre>RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: Fehler bei REFAF Befehl in c13 Kanal auf 10/31/2011 08:21:50
RMAN-10038: Datenbank-Session für Kanal c13 unerwartet beendet</pre>
<p>Nothing, not even an RMAN tracing was able to reveal more hints. The trace just told it in other words. No underlying ORA/TNS error or similar.</p>
<p>It finally turned out it were some parameters recently added to sqlnet.ora, I set SQLNET.RECV_TIMEOUT and SQLNET.SEND_TIMEOUT and the beast silently dropped RMAN channels that were idle for a while. The next command in this channel blew up the whole RUN block of the backup script.</p>
<p>I removed the parameters and it works again.</p>
<p>Be careful with your sqlnet.ora <img src='http://www.thebonsai.net/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>Yesterday I bought a Linksys WAP54G AP to extend the networt to the air here.</p>
<h2>First steps</h2>
<p>First, I only had problems. I had a problem connecting to the webinterface, because the manual mentions the wrong default user/pass pair for logon. Sick. By the way, this is the same manual that says that <em>SNMP</em> is the standard internet mail transfer protocol. Fsck it. I usually read manuals &#8211; but this one is just able to heat the air when you finally burn it. Maybe not even that.</p>
<p>Then, after finally logging in, I found this buggy, ugly and crappy webinterface. What a user expirience. Shit. At least it works to make the basic settings.</p>
<p>The AP finally worked for my wireless devices.</p>
<p>And then tests. Well, the firmware is not even able to do station monitoring or some other basic stuff. Argh.</p>
<h2>The solution to all the problems and crap</h2>
<p>DD-WRT&#8230; Flashed the thing (okay, I bricked it on the first try, my fault), booted, logged into the nice and usable webinterface, made the basic configuration, ready. I have shell access, basic tools, a Cron, remote syslogging and some more features (a rich featureset, compared to the original code image).</p>
<p>If you are able to put something like OpenWRT or DD-WRT on your lower priced Linksys devices: Do it.</p>
<h2>Rant to Cisco</h2>
<p>Are you really sure you want to put your Logo on this device? The original firmware sucks and the manual is written by idiots. Nothing I usually have in mind when I hear &#8220;Cisco Systems&#8221;. I&#8217;m aware that this is consumer hardware, but a bare minimum of quality should be there. For me, Cisco stands for high performance, reliability, quality &#8211; this thing, that carries a Cisco logo, is just a shadow of the functionality and quality of a Cisco console cable!</p>
<p>Also: On the internet I read in far too many forums that the technical support from Linksys is as good as no technical support. I&#8217;m glad that I didn&#8217;t need it.</p>
<p>&nbsp;</p>

			<content:encoded><![CDATA[<p>For some systems a downtime is complicated to organize, or bad at all. We have such a system, a RAC database.</p>
<p>In the past, all storage migration operations there had two problems that lead to downtime:</p>
<ul>
<li>CRS votedisk migration at best only with offline CRS</li>
<li>kick old devices from the device management in the operating system</li>
</ul>
<p>In December I migrated the system to something more modern</p>
<ul>
<li>SLES11</li>
<li>Oracle Grid Infrastructure (CRS/ASM) 11.2</li>
<li>Oracle Database 10.2.0.5 (yes, still quite old, but it has to be a 10.2 for now)</li>
</ul>
<p>The use of a modern Linux kernel (especially a modern SCSI stack) and 11gR2 infrastructure fixed all my trouble from the past.</p>
<h3>Votedisk</h3>
<p>With 11gR2 Grid Infrastructure, the clusterware manages its vital files (VD, OCR) using an ASM instance. A migration of the ASM diskgroups holding these files is now as easy as a migration of a normal diskgroup. ASM takes care of moving the votedisks and the OCR and collaborates with CRS here.</p>
<h3>Linux devices</h3>
<p>The new Linux kernels with a finally sane SCSI stack and native multipathing helps with the second problem. It&#8217;s not a problem anymore to remove old device references from the stack:</p>
<ul>
<li>deconfigure the devices from multipathd (not needed technically, since multipathd itself holds no device references)</li>
<li>remove the device references from the Linux device mapper

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #666666; font-style: italic;"># see /dev/mapper/* for the name</span>
dmsetup remove mpathX</pre></div></div>

</li>
<li>remove the LUNs from the SCSI stack

<div class="wp_syntax"><div class="code"><pre class="bash" style="font-family:monospace;"><span style="color: #666666; font-style: italic;"># X:X:X:X LUN number</span>
<span style="color: #7a0874; font-weight: bold;">echo</span> <span style="color: #000000;">1</span> <span style="color: #000000; font-weight: bold;">&gt;</span> <span style="color: #000000; font-weight: bold;">/</span>sys<span style="color: #000000; font-weight: bold;">/</span>bus<span style="color: #000000; font-weight: bold;">/</span>scsi<span style="color: #000000; font-weight: bold;">/</span>X:X:X:X<span style="color: #000000; font-weight: bold;">/</span>delete</pre></div></div>

</li>
</ul>
<p>After that, you can safely edit the FC zone &#8211; no errors should occur in any logs.</p>

			<content:encoded><![CDATA[<p>You know the need to sometimes manually switch logfiles with</p>

<div class="wp_syntax"><div class="code"><pre class="oracle11" style="font-family:monospace;"><span style="color: #993333; font-weight: bold; text-transform: uppercase;">ALTER</span> <span style="color: #993333; font-weight: bold; text-transform: uppercase;">SYSTEM</span> SWITCH LOGFILE;</pre></div></div>

<p>In a RAC with some more nodes, it can be quite disturbing to do that on all instances.</p>
<p>When you inspect the protocol files of the right services, you will find another, <em>undocumented</em> method:</p>

<div class="wp_syntax"><div class="code"><pre class="oracle11" style="font-family:monospace;"><span style="color: #993333; font-weight: bold; text-transform: uppercase;">ALTER</span> <span style="color: #993333; font-weight: bold; text-transform: uppercase;">SYSTEM</span> SWITCH <span style="color: #993333; font-weight: bold; text-transform: uppercase;">ALL</span> LOGFILE;</pre></div></div>

<p>This works at least on 10.2.0.5. Since it&#8217;s undocumented, I can&#8217;t tell you under which circumstances this command works or not, but it looks like always possible. Please find out yourself and let me know.</p>

			<content:encoded><![CDATA[<p>Ich lese zuletzt immer wieder Anschuldigungen dass das Vorgehen von Wikileaks kriminell sei. Fall: Dokumente von US Diplomaten und dem US Aussenministerium.</p>
<p>Leute, ganz ehrlich, wenn diese Dokumente schützenswert und geheim sind sollten sie vielleicht besser geschützt werden? Das geht doch auf keine Kuhhaut: Ein riesen Sicherheitsloch im eigenen Bau und dann rumweinen dass Wikileaks ja so kriminell ist?</p>
<h2><span style="color: #ff0000;">Wie albern.</span></h2>
<p>Vielleicht kann man jetzt auf urige Anschuldigungen warten, mit denen dann die Geheimdienste der Welt Wikileaks zerlegen dürfen, oder 80 US Divisionen marschieren in die Serverräume von Wikileaks ein und suchen ominöse C-Waffen, oder so&#8230; Vielleicht findet man auch den grossen bösen Wikileaks-Diktator den man dann medienwirksam hängen kann. Ausserdem ist das ein Bündnisfall und die gesamte westliche Welt muss in den Wikileaks Krieg ziehen.</p>
<p>Nebenbei: Mir ist klar dass die aussenpolitischen Partner und Gegner realistisch eingeschätzt werden müssen, das ist nicht der Punkt. Ich finde den Inhalt dieser Dokumente nicht wirklich überraschend. Lustig ist nur wie kindisch die Grossmacht USA jetzt rumbrüllt dass das ja alles so &#8220;kriminell&#8221; sei. Kriminell ist ihr Sicherheitsloch, ja, aber nicht die Veröffentlichung. Wie gesagt, wenn das Zeug so geheim und wichtig ist, sollen sie es schützen. Ich hoffe das tun sie wenigstens mit ihren A-Bomben &#8211; denn auf deren &#8220;Veröffentlichung&#8221; bin ich nicht scharf.</p>
<p>Und &#8211; ganz im Trend der Zeit &#8211; wird vielleicht die Freiheit im Netz und die Grundlage für solche Publikationen wie bei Wikileaks (zusammen mit Meinungen in diversen Blogs und anderen &#8220;gefährlichen&#8221; Erscheinungen im Internet) abgeschafft: Schliesslich muss man ja seine Bürger vor staatskritischen Meinungen von Terroristen schützen.<br />
<span id="more-220"></span><br />
<em>(nein, ich bin noch nicht ganz wach und etwas angefressen, vielleicht wird das ja nach dem nächsten Kaffee besser <img src='http://www.thebonsai.net/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' />  )</em></p>
<h2>UPDATE-01: 30.11.2010 07:15</h2>
<p>Die letzten paar Tage ist eine regelrechte Cyber-Hetzjagd gegen Wikileaks entbrannt. Da werden Domains gesperrt, Server zugemacht, PayPal Konten gesperrt usw. Da muss man sich schon fragen, in welcher Welt wir eigentlich leben &#8211; und die deutsche Regierung macht da bestimmt gerne mit.</p>
<p>Einen interessanten Satz habe ich unter einem Tagesschau.de-Artikel in den Kommentaren gelesen &#8211; der spricht eigentlich Bände über diesen derzeitigen Wahnsinn: <strong><span style="color: #ff0000;">Ein tausendstel dieses Aktionismus hätte ich mir gegen Kinderpornographie gewünscht.</span></strong></p>
<p>Ich kann anhand der ausgeführten Aktionen nur vermuten, dass bei manchen Leuten gerade die Nerven blank liegen &#8211; ob die wohl um ihre Karriere fürchten müssten?</p>
<h2>UPDATE-02: 04.12.2010 13:29</h2>
<p>Nur ein Link: <a title="US State Department announced to host world press freedom day in 2011" href="http://www.state.gov/r/pa/prs/ps/2010/12/152465.htm" target="_blank">http://www.state.gov/r/pa/prs/ps/2010/12/152465.htm</a></p>
<p><strong>Zusammenfassend:</strong> Die Vereinigten Staaten freuen sich mitteilen zu dürfen dass sie den internationalen Tag der Pressefreiheit 2011 der UNESCO ausrichten.</p>
<h2>UPDATE-03: 09.12.2010 12:55</h2>
<p>Anscheinend hat PayPal die eingefrorenen Beträge freigegeben. Link zu tagesschau.de: <a href="http://www.tagesschau.de/ausland/assange154.html" target="_blank">http://www.tagesschau.de/ausland/assange154.html</a></p>
<p>Aber irgendwie kann ich mir trotzdem nicht ganz vorstellen dass einem Riesen wie PayPal ein paar tausend geschlossener Konten wirtschaftlich was ausmachen. Trotzdem eine interessante Reaktion.</p>
<h2>UPDATE-03: 09.12.2010 15:47</h2>
<p>Ob diese Petition irgendwas bewegen wird? Wahrscheinlich nicht. Siehe <a href="http://www.avaaz.org/en/wikileaks_petition" target="_blank">http://www.avaaz.org/en/wikileaks_petition</a></p>
<h2>UPDATE-04: 10.12.2010 10:27</h2>
<p>Irgendwie scheint sich auch die UN besorgt über den Wahnsinn geäußert zu haben. Vielleicht gibt es ja doch noch vernünftige Institutionen?</p>
<h2>UPDATE-05: 14.12.2010 13:01</h2>

<div>Grundsätzlich wäre aber interessant wie seine derzeitige Dreiecksbeziehung GB/SE/US läuft und ausgeht <img src='http://www.thebonsai.net/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </div>
<div>
<h2>UPDATE-06: 18.12.2010 13:07</h2>
<p>Schon einige Tage nichts mehr geschrieben <img src='http://www.thebonsai.net/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p>Kurzfassung der interessantesten Dinge:</p>
<ul>
<li>Assange ist doch nicht TIME&#8217;s Person of the year</li>
<li>Assange ist auf Kaution frei und befindet sich noch in GB</li>
<li>Amerikanischer Politiker Bob Beckel ruft auf FOX News zur &#8220;illegalen Tötung&#8221; von Assange auf (wow&#8230;)</li>
