Full Transportable Export/Import White Paper

One of the really cool and helpful features in Oracle Database 12c is called Full Transportable Export/Import. It combines the basics of transportable tablespaces - of course cross-platform, cross-endianess, cross-version - with Data Pump taking care on all the stuff not stored in tables and indexes, such as views, synonyms, trigger, packages etc. And you can even reduce downtime by combining the feature with incrementally converted RMAN backups.

And the best thing: this will work with an Oracle Database 11.2.0.3/4 to Oracle Database 12c - so you don't have to be on Oracle Database 12c in order to leverage from that cool new feature.

See the brand new White Paper about Full Transportable Export/Import here:

The MAGIC Questions

Almost every week Roy, Carol and I receive one or more emails in the following style:

"Hey, we (or my customer) plan(s) an upgrade to Oracle 11g. We (or the customer) wants zero downtime. Currently we (or they) are on AIX with Oracle 10g (and someold  9i) databases. Can we get an advice please?"

or another one here ...

"Upgrade from 8i to 11g. The customer's database is 28 TB (quite big!). Downtime is 5-6 hours. It's on AIX. And it's an it's an Oracle EBS database"

Well, in both cases we lack a lot of useful information - or sometimes things are almost impossible or simply wishful thinking. So we have a collection of (we call them) The Magic Questions. Once those are answered upfront it is way easier to give a helpful advice.

  • Will you exchange the hardware?
  • Will you change to a new OS version?
  • Will you change to an entire new OS architecture?
  • Will you change the database characterset?
  • Do you plan to consolidate (schema/database/...)?
  • Number of databases you plan to upgrade or migrate?
  • Size of database(s)?
  • Exact source and target Oracle versions?
  • Maximum allowed downtime per database?
  • Fallback requirements?
  • Test environment available? Testing tools?
  • Does a performance baseline exist?
  • Changes required to enable new features?
  • RAC/Grid Infrastructure already in use or planned?

Once we get the answer and (even more helpful) a sheet describing the entire landscape in more detail we will be able to give some advice.

Back Home ...

Now finally back from my short trip to Johannesburg, South Africa. Flying out Monday overnight, returning Friday morning after another overnight flight (all Eco). But thanks to Turkish Airlines - including the short stop-over in Istanbul was worth it as the seating comfort in Turkish's economy class is far better than Lufthansa's - as is the food and especially the entertainment system, the service ... almost everything. And luckily the Turkish Airline's employees didn't go on strike in Thursday :-)

But after running now 6 internal Oracle Database 12c: Upgrade, Migrate and Consolidate workshops in the US and in EMEA I've learned a lot from our over 180 participants doing the full Hands-On part of the workshop.

I'm really looking forward to the release date :-)

AIB - Allied Irish Banks - Upgrade Success

AIB LogoJust a quick note on Allied Irish Banks (AIB), a customer colleagues and I did work with on their upgrade and migration to Oracle Database 11.2  They've done a tremendous job and finally were present at OOW 2012 in San Francisco. Mina, my presales colleague from Oracle Ireland, gave me heads up about the short videos they've produced in SF with the AIB folks now being available on o.com.

Mile High ... Collaborate 2013 in Denver

Collaborate 2013 is almost over - we are running our final Hands-On-Lab session right now in the Convention Center in Denver, Colorado. For those seeking for the Hands-On-Lab Instructions for our session please be patient until Oracle Database 12c gets released. As soon as this happens we'll offer you the HOL Instructions plus many more information about Oracle Database 12c and the different upgrade and migration paths.

Denver apparently has become my no.3 US city - not only because the mountains are so close by. But the city itself is really worth a visit :-) Please find some impressions below :-) And see you next year at Collaborate 2014 on April 7-11 in Las Vegas.


Yes, again SNOW in Denver ... well ...

Long time no update ...

I deeply apologize for not updating the blog for some weeks now. I'm still working for Oracle, still in the same group - but due to some other things going on in preparation for Oracle Database 12c I had either no time or simply nothing to report at the moment. I didn't want to bore you with Oracle Database 11.2 stuff as the slides don't get changed right now. Oracle Database 11.2.0.4 patchset should be available sometime in early summer with a good bunch of fixes included.

Roy and me had delivered the first internal only Upgrade, Migrate and Consolidate to Oracle Database 12c workshops in Redwood Shores and Colorado Springs mainly to Support and Development colleagues. That was great fun as we did include 3 nice parts for hands-on as well. And we've got so much good and valuable feedback.

In the near future Roy will come over to Europe and end of April we'll deliver the workshop again in Paris, Munich and Reading. South Africa will follow in May - and maybe Orlando in the US. As soon as Oracle Database 12c will get released we'll be ready to go for customer workshops as well. So stay tuned for upcoming dates and events.

- Mike

PS: This happens when you'd like to fly back home from Denver, Colorado, in late March ...now I know what a Blizzard feels like ... and the picture isn't blurry ... it's simply PLENTY of snow ...

Potential check for corruptions

Having a corruption somewhere in the database is one of the worst case scenarios I could ever imagine - especially if it "sleeps" somewhere in the data dictionary. Recently I did talk to a customer who encountered a failing upgrade due to a data dictionary corruption gotten introduced in an earlier release.

What can you do to check your database(s) prior to an upgrade or generally from time to time? Actually I know now two powerful possibilities: 

  • hcheck.sql
    See MOS Note:136697.1
    This script will check for known problems in Oracle8i, Oracle9i, Oracle10g and Oracle 11g.
    You will need to create
    hOut Helper Package first - please see MOS Note:101468.1 to download the script hout.sql
  • RMAN validation:
    RMAN> backup check logical validate database;
    See MOS Note:836658.1 for further details - and you can run this with multiple parallel channels to speed up the run

New version of the huge Upgrade to 11.2 slides uploaded

It took a while to create a new and corrected version of the huge (sorry ... now over 500 slides) Upgrade and Migration to Oracle Database 11.2 slide deck.
But you'll find it to the right in the Slides Download Center.

As we will start with a new deck for the upcoming Oracle Database 12c slide set the old one may not see changes anymore from now on. And thanks a lot to everybody who has been helped to correct typos, syntax or naming errors and highlighted topics or misbehavior of the database we haven't seen before :-)

Happy New Year!!! And my top ten 2012 songs ...


Happy New Year

to all of you, your families and friends wherever you live on the globe :-)



And - similar to last year - here's my list of the best 2012 songs based on the CDs or LPs I did purchase that year - and I didn't buy much music this year but did focus on older stuff I had on my iPod for quite a while or just started listening. For instance I did get two UFO compilations, The Chrysalis Years and the The Decca Years, after listening to Try Me in the best bar on the globe.

But back to my top 2012 releases and best songs.

Anathema - Weather Systems


This is my true number 1 album of 2012. I know Anathema from Liverpool since 1996 and had the chance this year in early November to see them live for the first time. And even two months after that concert I would still claim that this was the best concert I've ever been to. Period. Just by they way: this album became also the 2012 critic's choice of UK's Prog magazine. And there's a reason for that ;-)

Listen to:
Untouchable Part 2 and The Gathering Of The Clouds


Katatonia
- Dead End Kings


Similar to Anathema Katatonia do exist since the early 90's. And back then their style was way harder than today. Bought this CD at Rasputin Records during OOW in San Francisco and did listen to it almost every second day since then. Don't get distracted by the strange cover - some bands need to have such an artwork.

Simply listen to these two songs:
Lethean and Racing Heart


Steve Wilson - Get What You Deserve - Live in Mexico City


Very rarely I buy DVDs or BluRays as I like more listening to music than watching it. But this one is an exception (and it has the full concert on a double CD included as well). Steve Wilson is the mastermind of Porcupine Tree, one of my true favorite bands. And he seems to sleep just 3 hours per night if you look at all the projects he had done in the past 3 years. This DVD/CD/BluRay is the entire concert of Steve Wilson's solo project after releasing Grace For Drowning in 2011. And sonically as well as visually this concert is really great.

Listen to Harmony Korine and Part of Me


Baroness - Yellow & Green


Baroness 2012 release is my "almost" number 1 album of 2012. Actually it's two albums, Yellow and Green combined into one release. I did purchase that after reading a review in German magazine Der Spiegel a while back in July 2012. The author called it The Album Of The Year ... in July. The band is based in Savannah, Georgia, exists since 2003 and had been already on tour in the past supporting Metallica. I got really touched by the variety of styles, the rough rawness and power combined with sweet harmonies - wow! Some songs simply blew me away :-)

Listen to:
Take My Bones Away and Twinkler and Psalms Alive


Die Toten Hosen - Ballast der Republik


Just a month ago a documentary in German TV did show the entire career of Die Toten Hosen now spanning over 30 years. They started as a punk band in Düsseldorf in 1982 but today they are playing true rock music. Plenty of their songs were frequently played some 20 years ago at our school parties. It's still not their best album ever (that's Ein Kleines Bisschen Horrorschau, the German interpretation of Clockwork Orange with Hier kommt Alex)  but I did listen to some of their songs very often when walking through San Francisco this year at OOW - and I have them on heavy rotation in my car for longer drives (sometimes there's no speed limit on German Autobahns) ;-)

Listen to Altes Fieber and Tage Wie Diese

Creating ASM for test purposes in the file system

First of all, I'm back after pausing for a while - sorry for not updating the blog in the past weeks ... and you won't see many updates in the following weeks as it'll be holiday season (and we Germans have sooooo many public holidays) :-)

Anyway, back to tech topics. Today I want to test Oracle Restart upgrades. Oracle Restart internally is called SIHA (Single Instance High Availability) which explains the topic a bit more. Basically it means having your database reside in ASM and let Oracle Clusterware take care on it, even though you don't have a cluster. Not a bad idea as this can be very helpful in real world environments. But I did realize that the entire process is not documented in all details. So I'd thought I should give this a try.

The first challenge I do face: I have just one disk in my machine - so I'll have to tweak ASM a bit to make it work with files on the file system.

Creating two empty strawman files in file system with dd is not a big deal:
$ dd if=/dev/zero of=/oradata/ASM/dg_DATA bs=8192 count=1000000 oflag=direct
1000000+0 records in
1000000+0 records out
8192000000 bytes (8.2 GB) copied, 336.371 seconds, 24.4 MB/s
[V112] oracle@localhost:/oradata
$ dd if=/dev/zero of=/oradata/ASM/dg_BCK bs=8192 count=500000 oflag=direct
500000+0 records in
500000+0 records out
4096000000 bytes (4.1 GB) copied, 246.021 seconds, 16.6 MB/s

But the next step is to start the cssd (Cluster Synchronization Services Demon) in my Oracle Database 10.2.0.5 installation from within the $ORACLE_HOME/bin directory:
[root@localhost bin]# . localconfig add
/etc/oracle does not exist. Creating it now.
Successfully accumulated necessary OCR keys.
Creating OCR keys for user 'root', privgrp 'root'..
Operation successful.
Configuration for local CSS has been initialized
Adding to inittab
Startup will be queued to init within 30 seconds.
Checking the status of new Oracle init process...
Expecting the CRS daemons to be up within 600 seconds.
CSS is active on these nodes.
        localhost
CSS is active on all nodes.
Oracle CSS service is installed and running under init(1M)

Otherwise no chance for ASM to start up.

Now my attempts to use simply DBCA (Database Configuration Assistant) to creare the ASM instance on these two strawman files did not work as the DBCA didn't want to recognize the "disks". So back to good old command line. By the way, there's a MOS Note out there which may be helpful as well (but didn't work in my case).
How To Create ASM Diskgroups using NFS/NAS Files? (Doc ID 731775.1)

  1. Create a password file for ASM instance in $ORACLE_HOME/dbs
  2. Create a fresh init.ora for ASM within the same directory having the following parameters set:
    _asm_allow_only_raw_disks='FALSE'
    asm_diskstring='/oradata/ASM/dg*'
    asm_power_limit=4
    instance_type=asm
  3. With these parameter set I could bring the instance into MOUNT state ready to create the two disk groups after setting the ORACLE_SID=+ASM in the environment:
    SYS:+ASM> create diskgroup DATA external redundancy disk '/oradata/ASM/dg_DATA';
    Diskgroup created.
    SYS:+ASM>  create diskgroup BCK  external redundancy disk '/oradata/ASM/dg_BCK';
    Diskgroup created.

Starting up ASM did work now well after shutting it down first - and a check for SELECT path from V$ASM_DISK did show me my disks.

Next step - simply - is to create a database with DBCA inside of ASM. So the first part of my test did complete.

... to be continued soon ...

Rules Manager and Expression Filter getting removed

I doubt that many people are using the Oracle features "Rules Manager" and "Expression Filter" as usually people handle these things (such as ensuring that a zip code or a car number plate has a certain format) within the application code and not inside the database. Oracle Beehive for instance uses that just on the side. 

Anyway, just learned today that Rules Manager and Expression Filter components will get removed once our next database release most likely called Oracle Database 12c will get released. So before upgrading to Oracle Database 12c you can remove EXF and RUL components (SELECT COMP_ID FROM DBA_REGISTRY WHERE COMP_ID IN ('EXF','RUL'); ).

You'd simply do that by executing the following script before upgrade:
SQL> @?/rdbms/admin/catnoexf.sql
This will clean up Rules Manager and Expression Filter components inside the database. You could run ?/rdbms/admin/catnorul.sql before but I believe catnoexf.sql will clean up everything already.

And you'll find all this information plus guidelines for migration of existing content in MOS Note: 1233535.1 - Obsolescence Notice: Rules Manager and Expression Filter Features of Oracle Database

Where's Gangnam?

When somebody did mention "PSY" during a dinner at OOW this year with customers and colleagues from Korea I was completely clueless. I even didn't understand correctly who or what "PSY" is. I did forget about that until last week as a German online magazine did report on over 500 mio youtube hits for "Gangnam Style". Well ... I didn't know that I've almost missed a global phenomenon. And now I've learned that the song is omnipresent in Korea (and not only here) - and Gangnam is a really nice (and expensive) quarter of Seoul :-) not that far away from my hotel.

And if you need some rest during your lunch break you may watch these youtube vids - but don't blame me if you don't get the song out of your head anymore ...

And NO - that's not the type of music I'd usually listen to!!!

OTN APAC Tour 2012: Bangkok, Thailand - RECAP

Thanks to everybody who did attend at the OTN APAC Tour in Bangkok on Monday, Oct 21. It was a pleasure for me to be back in Bangkok again even though I didn't have much time again due to my overnight flight to Seoul after the workshop.

But thanks for your questions - I will follow up as soon as I'm getting back home. And thanks to Francisco Alvarez, Oracle ACE Director from New Zealand, for inviting me. It was a pleasure presenting together with Francisco, Kamran Nagayev, Oracle ACE Director from Azerbaidjan and Tanakorn Tavornsasnavong from Bangkok. I have learned a lot during that day.

Mike Dietrich, Francisco Alvarez Munos, Kamran Agayev

In case you'd like to download my presentations from this day please find theme via this link. You may access the other slides on either the local OTN page or get them directly from Francisco's blog and Kamran's blog (and you'll find a lot of excellent and helpful articles there as well).

And many thanks to the local OTN group organizing the entire event so well :-) 

Hope to see you soon again :-)

Migration of a database from 32bit to 64bit

Database migrations from an 32bit environment to an 64bit environment keeping the same platform architecture (e.g. moving an Oracle 10.2.0.5 database from MS Windows XP 32bit to MS Windows Server 2003 64bit) does not happen that often anymore. But still we see them getting done. And there are a few things to note when doing such a move.

First of all the important question is:
Will you upgrade your database as part of this move - Yes or No?

If you say "Yes" then you are almost done with that topic as we will take care of that bitnes move during the upgrade. The only thing you have to take care is OLAP in case you are using OLAP Option with Analytic Workspaces (AW) by yourself. Those store data in Binary LOBs - and in order to move AWs from 32bit to 64bit you have to export your AWs prior to the move - and import them later on. People who don't use OLAP don't have to take care on this. In that case you'll have to drop AWs after the export - please see MOS Note:386990.1 for further details.

But if you say "No" (meaning: no upgrade actions involved - you keep your database version) then you have to make sure to invalidate all packages and stored code in the database before you shutdown your database in the 32bit environment and prior to moving it over. And the same rule as above for OLAP applies once you use the OLAP Option.

In the source environment:

startup upgrade;    -- [or startup migrate; -- for Oracle 9i]
@?/rdbms/admin/utlirp.sql
shutdown immediate

In the destination environment:

startup upgrade
@?/olap/admin/xumuts.plb --Only if OLAP Option is installed
@?/rdbms/admin/utlrp.sql

The script utlirp.sql will invalidate all packages and stored code, utlrp.sql will recompile - and xumuts.plb will rebuild the OLAP Analytic Workspaces in case you have the OLAP Option installed.

OOW 2012:
Slides Download

Hm ... you might ask yourself why there are no Oracle Database 12c slides available for download, neither in the OOW 2012 content system nor on our blog (and I believe nowhere else).

Simple reason: As long as Oracle Database 12c is not released and available we are not allowed to offer slides for download. Therefore people were simply taking pictures during the 12c sessions with their phones, iPods and cameras. Roy took a nice shot:


Sorry for that - we'll make the content available as soon as Oracle Database 12c gets released.

In between you can download our OOW 2012 talk Database Upgrades on Steroids: Real Speed, Real Customers, Real Secrets as PDF (3.4MB) - but the 12c content is currently not in that PDF. But a lot of information applies to your source database and/or to any upgrade - so it still might be helpful. And unfortunately the same 12c rule applies to the slides guiding you through our Hands-On-Lab on Tuesday.

Thanks :-)

OOW 2012:
Kings of Leon & Pearl Jam - Appreciation Event

June 15, 1992 - that was actually the day when Pearl Jam played their first concert in Serenadenhof in my hometown, Nürnberg. Oups ... that's over 20 years ago ... ;-)

So I was so happy to get a ticket to this year's OOW 2012 appreciation event on Treasure Island. Every year it amazes me over and over again how the organizers manage it logistically to bring almost 40,000 people to and back from the island. Food was ... I would say fairly ok ... and beer (as always) is not - actually even though I'm not a beer drinker I wouldn't call it beer

Kings of Leon did start. I like them a lot and owe their 2008 album Only By Night. That was a good start to warm up the crowd.

And then Pearl Jam took over - and ... wooooooow ... they are such a great live band. First of all as far as I understood they were donating the money they've got for that gig to an NGO. And Eddie Vedder's voice is simply striking ... I had shivers running down my spine. They played a good excerpt of their +20 years career closing down with Alive at the very end. It seemed to everybody that the band had real fun playing there - and it was sooooo good. Thanks a lot to the person who did organize me a ticket :-)

Catching my bus back to my hotel area down at Fisherman's Wharf worked well - but I must have fallen asleep 5 minutes after we've left the parking lot. The next thing I did recognize was the bus driver pushing the breaks at Northpoint. What a wonderful night ...
