  • Craftsmanship Tour: Day 2 Obtiva

    - by Liam McLennan
    I like Chicago. It is a great city for travellers. From the moment I got off the plane at O’Hare everything was easy. I took the train to ‘the Loop’ and walked around the corner to my hotel, Hotel Blake on Dearborn St. Sadly, the elevated train lines in downtown Chicago remind me of ‘Shall We Dance’. Hotel Blake is excellent (except for the breakfast) and the concierge directed me to a pizza place called Lou Malnati's for Chicago style deep-dish pizza. Lou Malnati’s would be a great place to go with a group of friends. I felt strange dining there by myself, but the food and service were excellent. As usual in the United States the portion was so large that I could not finish it, but oh how I tried. Dave Hoover, who invited me to Obtiva for the day, had asked me to arrive at 9:45am. I was up early and had some time to kill so I stopped at the Willis Tower, since it was on my way to the office. Willis Tower is 1,451 feet (442 m) tall and has an observation deck at the top. Around the observation deck are a set of acrylic boxes, protruding from the side of the building. Brave soles can walk out on the perspex and look between their feet all the way down to the street. It is unnerving. Obtiva is a progressive, craftsmanship-focused software development company in downtown Chicago. Dave even wrote a book, Apprenticeship Patterns, that provides a catalogue of patterns to assist aspiring software craftsmen to achieve their goals. I spent the morning working in Obtiva’s software studio, an open xp-style office that houses Obtiva’s in-house development team. For lunch Dave Hoover, Corey Haines, Cory Foy and I went to a local Greek restaurant (not Dancing Zorbas). Dave, Corey and Cory are three smart and motivated guys and I found their ideas enlightening. It was especially great to chat with Corey Haines since he was the inspiration for my craftsmanship tour in the first place. After lunch I recorded a brief interview with Dave. Unfortunately, the battery in my camera went flat so I missed recording some interesting stuff. Interview with Dave Hoover In the evening Obtiva hosted an rspec hackfest with David Chelimsky and others. This was an excellent opportunity to be around some of the very best ruby programmers. At 10pm I went back to my hotel to get some rest before my train north the next morning.

  • How do I get rid of the drive mount confirmation question for sshFS on boot?

    - by Dave M G
    With help from this site, I was able to set up an SSHFS connection between two computers on my LAN so that one auto mounts on the other at boot time. Everything works, but there is this annoying confirmation that comes up whenever I boot: An error occurred while mounting /home/dave/Mythbuntu. Press S to skip mounting or M or Manual recovery If I press S, then booting continues, and my drive is mounted as hoped, so it seems like even though I "skipped" it, maybe it tried again and succeeded later in the boot process. I followed the instructions here to set up "if up / if down" scripts, and here is my current /etc/fstab: sshfs#[email protected]:/home/mythbuntu /home/dave/Mythbuntu fuse auto,users,exec,uid=1000,gid=1000,allow_other,reconnect,transform_symlinks,BatchMode=yes 0 0 Although the mounting is working, this step of having to press S every time I boot is obviously kind of a hassle. How do I configure my computer so I don't have to do that, and so that my other computer will still automount?

  • Python soap using soaplib (server) and suds (client)

    - by Celso Axelrud
    This question is related to: http://stackoverflow.com/questions/1751027/python-soap-server-client In the case of soap with python, there are recommendation to use soaplib (http://wiki.github.com/jkp/soaplib) as soap server and suds (https://fedorahosted.org/suds/) as soap client. My target is to create soap services in python that can be consumed by several clients (java, etc). I tried the HelloWorld example from soaplib (http://trac.optio.webfactional.com/wiki/HelloWorld). It works well when the client is also using soaplib. Then, I tried to use suds as client consuming the HelloWorld services and it fail. -Why this is happening? Does soaplib server has problems to consumed by different clients? Here the code for the server: from soaplib.wsgi_soap import SimpleWSGISoapApp from soaplib.service import soapmethod from soaplib.serializers.primitive import String, Integer, Arraycode class HelloWorldService(SimpleWSGISoapApp): @soapmethod(String,Integer,_returns=Array(String)) def say_hello(self,name,times): results = [] for i in range(0,times): results.append('Hello, %s'%name) return results if __name__=='__main__': from cherrypy.wsgiserver import CherryPyWSGIServer #from cherrypy._cpwsgiserver import CherryPyWSGIServer # this example uses CherryPy2.2, use cherrypy.wsgiserver.CherryPyWSGIServer for CherryPy 3.0 server = CherryPyWSGIServer(('localhost',7789),HelloWorldService()) server.start() This is the soaplib client: from soaplib.client import make_service_client from SoapServerTest_1 import HelloWorldService client = make_service_client('http://localhost:7789/',HelloWorldService()) print client.say_hello("Dave",5) Results: >>> ['Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave'] This is the suds client: from suds.client import Client url = 'http://localhost:7789/HelloWordService?wsdl' client1 = Client(url) client1.service.say_hello("Dave",5) Results: >>> Unhandled exception while debugging...

  • Big Data – Operational Databases Supporting Big Data – Key-Value Pair Databases and Document Databases – Day 13 of 21

    - by Pinal Dave
    In yesterday’s blog post we learned the importance of the Relational Database and NoSQL database in the Big Data Story. In this article we will understand the role of Key-Value Pair Databases and Document Databases Supporting Big Data Story. Now we will see a few of the examples of the operational databases. Relational Databases (Yesterday’s post) NoSQL Databases (Yesterday’s post) Key-Value Pair Databases (This post) Document Databases (This post) Columnar Databases (Tomorrow’s post) Graph Databases (Tomorrow’s post) Spatial Databases (Tomorrow’s post) Key Value Pair Databases Key Value Pair Databases are also known as KVP databases. A key is a field name and attribute, an identifier. The content of that field is its value, the data that is being identified and stored. They have a very simple implementation of NoSQL database concepts. They do not have schema hence they are very flexible as well as scalable. The disadvantages of Key Value Pair (KVP) database are that they do not follow ACID (Atomicity, Consistency, Isolation, Durability) properties. Additionally, it will require data architects to plan for data placement, replication as well as high availability. In KVP databases the data is stored as strings. Here is a simple example of how Key Value Database will look like: Key Value Name Pinal Dave Color Blue Twitter @pinaldave Name Nupur Dave Movie The Hero As the number of users grow in Key Value Pair databases it starts getting difficult to manage the entire database. As there is no specific schema or rules associated with the database, there are chances that database grows exponentially as well. It is very crucial to select the right Key Value Pair Database which offers an additional set of tools to manage the data and provides finer control over various business aspects of the same. Riak Rick is one of the most popular Key Value Database. It is known for its scalability and performance in high volume and velocity database. Additionally, it implements a mechanism for collection key and values which further helps to build manageable system. We will further discuss Riak in future blog posts. Key Value Databases are a good choice for social media, communities, caching layers for connecting other databases. In simpler words, whenever we required flexibility of the data storage keeping scalability in mind – KVP databases are good options to consider. Document Database There are two different kinds of document databases. 1) Full document Content (web pages, word docs etc) and 2) Storing Document Components for storage. The second types of the document database we are talking about over here. They use Javascript Object Notation (JSON) and Binary JSON for the structure of the documents. JSON is very easy to understand language and it is very easy to write for applications. There are two major structures of JSON used for Document Database – 1) Name Value Pairs and 2) Ordered List. MongoDB and CouchDB are two of the most popular Open Source NonRelational Document Database. MongoDB MongoDB databases are called collections. Each collection is build of documents and each document is composed of fields. MongoDB collections can be indexed for optimal performance. MongoDB ecosystem is highly available, supports query services as well as MapReduce. It is often used in high volume content management system. CouchDB CouchDB databases are composed of documents which consists fields and attachments (known as description). It supports ACID properties. The main attraction points of CouchDB are that it will continue to operate even though network connectivity is sketchy. Due to this nature CouchDB prefers local data storage. Document Database is a good choice of the database when users have to generate dynamic reports from elements which are changing very frequently. A good example of document usages is in real time analytics in social networking or content management system. Tomorrow In tomorrow’s blog post we will discuss about various other Operational Databases supporting Big Data.

  • SQLAuthority News – Presented Technical Session at DevReach 2013, Sofia, Bulgaria – Oct 1, 2013

    - by Pinal Dave
    Earlier this month, I had a fantastic time presenting at DevReach 2013, in Sofia, Bulgaria on Oct 1, 2013. DevReach strives to be the premier developer conference in Central and Eastern Europe. It is organized annually in Sofia, Bulgaria. The 8th edition of the conference is moving to a new and bigger venue: Sofia Event Center. In my career, I have presented over 9 different countries (India, USA, Canada, Singapore, Hong Kong, Malaysia, Sri Lanka, Nepal, Thailand), this was the first time for me to present in Europe. DevReach was perfect places to start my journey in Europe as an evangelist. The event was one of the most organized event I have ever come across in my life. The DevRech organization team had perfected every minute detail of the event to perfection. After the event was over I had the opportunity to see Sofia for one day. I presented with one of my most favorite Database Worst Practices Session.

  • How to eliminate NULL fields in TSQL

    - by salvationishere
    I am developing a TSQL query in SSMS 2008 R2. I am trying to develop this query to identify one record / client. Because some of these values are NULL, I am currently doing LEFT JOINS on most of the tables. But the problem with the LEFT JOINs is that now I get 1 record for some clients. But if I change this to INNER JOINs then some clients are excluded entirely because they have NULL values for these columns. How do I limit the query result to just one record / client regardless of NULL values? And if there are non-NULL values then I want it to choose the record with non-NULL values. Here is some of my current output: group_profile_id profile_name license_number is_accepting is_accepting_placement managing_office region vendor_name vendor_id applicant_type Office Address status_description Cert Date2 race ethnicity_desc religion 9CD932F1-6BE1-4F80-AB81-0CE32C565BCF Atreides Foster Home 1 Atreides1 1 Yes Manchester, NH Gulf Atlantic Atreides1 00000007 Treatment Foster Home 4042 Arrakis Avenue, Springfield, VT 05156 Open/Re-opened 2011-06-01 00:00:00.000 NULL NULL NULL DCE354D5-A7CC-409F-B5A3-89BF664B7718 Averitte, Leon and Sandra 00000044 1 Yes Birmingham, AL Gulf Atlantic AL Averitte, Leon and Sandra 00000044 Treatment Foster Home 3816 5th Avenue, Bessemer, AL 35020, (205)482-4307 Open/Re-opened 2011-08-05 00:00:00.000 NULL NULL NULL DCE354D5-A7CC-409F-B5A3-89BF664B7718 Averitte, Leon and Sandra 00000044 1 Yes Birmingham, AL Gulf Atlantic AL Averitte, Leon and Sandra 00000044 Treatment Foster Home 3816 5th Avenue, Bessemer, AL 35020, (205)482-4307 Open/Re-opened 2011-08-05 00:00:00.000 Caucasian/White Non Hispanic NULL AD02A43C-6F38-4F35-8C9E-E12422690BFB Bass, Matthew and Sarah 00000076 1 Yes Jacks on, MS Central Gulf Coast MS Bass, Matthew and Sarah 00000076 Treatment Foster Home 506 Eagelwood Drive, Florence, MS 39073, (601)665-7169 Open/Re-opened 2011-04-01 00:00:00.000 NULL NULL NULL AD02A43C-6F38-4F35-8C9E-E12422690BFB Bass, Matthew and Sarah 00000076 1 Yes Jackson, MS Central Gulf Coast MS Bass, Matthew and Sarah 00000076 Treatment Foster Home 506 Eagelwood Drive, Florence, MS 39073, (601)665-7169 Open/Re-opened 2011-04-01 00:00:00.000 Caucasian/White NULL Baptist You can see that both Averitte and Bass profile names have one record with NULL race, ethnicity, religion.

Shoutouts: Jordan Knight has a demo up of a project he did for DigiGirlz: DigiGirlz, Deep Zoom and Azure, hopefully we'll get source later :) Jeremy Likness has a must-read post on his Ten Reasons to use the Managed Extensibility Framework I put this on another post earlier, but if you want some desktop bling for WP7, Ozymandias has some: I Love Windows Phone Wallpaper If you're not going to be in 'Vegas next week, Tim Heuer reminds us there's an alternative: Watch the Silverlight 4 Launch event and LIVE QA with ScottGu and others From SilverlightCream.com: Ghost Lines in Silverlight Alan Mendelevich reports an issue when drawing lines with odd coordinate values. He originated it in Silverlight 3, but it is there in SL4RC as well... check it out and leave him a comment. A Framework to Animate WPF and Silverlight Pages Similar to the PowerPoint Slides Siyamand Ayubi has an interesting post up on animating WPF or Silverlight pages to make them progress in the manner of a PPT slideshow. And it can also make phone calls… Rudi Grobler has a list of 'tasks' you can do with WP7 such as PhoneCallTask or EmailComposeTask ... looks like this should be plasticized :) Using the GPS, Accelerometer & Vibration Controller Rudi Grobler is also investigating how to use the GPS, Accelerometer, and Vibration in WP7 with a bunch of external links to back it up.

  • SQLAuthority News – Presented Soft Skill Session on Presentation Skills at SQL Bangalore on May 3, 2014

    - by Pinal Dave
    I have presented on various database technologies for almost 10 years now. SQL, Database and NoSQL have been part of my life. Earlier this month, I had the opportunity to present on the topic Performing an Effective Presentation. I must say it was blast to prepare as well as present this session. This event was part of the SQL Bangalore community. If you are in Bangalore, you must be part of this group. SQL Bangalore is a wonderful community and we always have a great response when we present on technology. It is SQL User Group and we discuss everything SQL there. This month we had SQL Server 2014 theme and we had a community launch of SQL Server. We have the best of the best speakers presenting on SQL Server 2014 technology. The event had amazing speakers and each of them did justice to the subject. You can read about this over here. In this session I told a story from my life. I talked about who inspired me and how I learned to speak in public. I told stories about two legends  who have inspired me. There is no video recording of this session. If you want to get resources from this session, please sign up my newsletter at http://bit.ly/sqllearn. Well, I had a great time at this event. We had over 250 people showed up at this event and had a grand  time together. I personally enjoyed a session of Amit Benerjee, Balmukund Lakhani and Vinod Kumar. Ken and Surabh also entertained the audience. Overall, this was a grand event and if you were in Bangalore and did not make it to this event. You did miss out on a few things. Here are a few photos of this event.

  • SQL Saturday 194 - Exeter

    - by Dave Ballantyne
    Many kudos goes to Jonathan and Annette Allen and the others on the team for confirming SQL Saturday 194 in Exeter on the 8th and 9th of March.  The event home page is here http://www.sqlsaturday.com/194/eventhome.aspx and I delighted that myself and Dave Morrison will be presenting a full day pre-con on the 8th on favourite subjects “TSQL and Internals”. Here is the full abstract : TSQL and internals - When faced with performance issues there are many lines of attack. Tuning the engine itself can get you so far, however for maximum effect you need to understand how the engine and how it translates SQL statements into performable actions. This is not a simple task, it is a massive task to deal with a multi-table join and the number of permutations can be immense. To back up this knowledge, we can create better performing TSQL and understand the impact that is has upon the engine and recognize the pitfalls and gotcha’s that exist in SQLServer. Ultimately, there is no ‘best way’ to perform a single task only many variations of ‘it depends’ , but now we can pick the most appropriate option for the required dataload. Over the years, there have been many myths and misconceptions have grown around the product, some have basis in older versions and some are just wrong. Continuing to build on the knowledge given so far these issue will be explored and broken down and proved or disproved. Finally we will look to the future and explore SQL Server 2012 and the new functionality that that brings and some of the common uses that we will be able to address. After completion of this days pre-con, attendees will have a more complete knowledge of execution plans, and how they relate to the physical and logical actions that SQLServer will be executing on their behalf. The attendees will also have a more rounded and fuller knowledge of TSQL and the implications of incorrectly defining a query. Dave is a fountain of knowledge on execution plans and optimizer internals and ,though i may flatter myself, I’m no shrinking violet when it comes to TSQL and such matters.  I hope that if you cant join us, then there are other pre-cons available from other experts in their fields that may ‘float you boat’ too.  The pre-con page is http://sqlsouthwest.co.uk/SQLSaturday_precon.htm Also, excitingly, this pre-con day is sponsored by Fusion-IO which is a great boon for the day. If you want a more of this then i am offering a 2 day TSQL course starting on the 19th of March. More details on this are available here

  • MySQL – Learning MySQL Online in 6 Hours – MySQL Fundamentals in 320 Minutes

    - by Pinal Dave
    MySQL is one of the most popular database language and I have been recently working with it a lot. Data have no barrier and every database have their own place. I have been working with MySQL for quite a while and just like SQL Server, I often find lots of people asking me if I have a tutorial which can teach them MySQL from the beginning. Here is the good news, I have written two different courses on MySQL Fundamentals, which is available online. The reason for writing two different courses was to keep the learning simple. Both of the courses are absolutely connected with other but designed if you watch either of the course independently you can watch them and learn without dependencies. However, if you ask me, I will suggest that you watch MySQL Fundamentals Part 1 course following with MySQL Fundamentals Part 2 course. Let us quickly explore outline of MySQL courses. MySQL Fundamental – 1 (157 minutes) MySQL is a popular choice of database for use in web applications, and is a central component of the widely used LAMP open source web application software stack. This course covers the fundamentals of MySQL, including how to install MySQL as well as written basic data retrieval and data modification queries. Introduction (duration 00:02:12) Installations and GUI Tools (duration 00:13:51) Fundamentals of RDBMS and Database Designs (duration 00:16:13) Introduction MYSQL Workbench (duration 00:31:51) Data Retrieval Techniques (duration 01:11:13) Data Modification Techniques (duration 00:20:41) Summary and Resources (duration 00:01:31) MySQL Fundamental – 2 (163 minutes) MySQL is a popular choice of database for use in web applications, and is a central component of the widely used LAMP open source web application software stack. In this course, which is part 2 of the Fundamentals of MySQL series, we explore more advanced topics such as stored procedures & user-defined functions, subqueries & joins, views and events & triggers. Introduction (duration 00:02:09) Joins, Unions and Subqueries (duration 01:03:56) MySQL Functions (duration 00:36:55) MySQL Views (duration 00:19:19) Stored Procedures and Stored Functions (duration 00:25:23) Triggers and Events (duration 00:13:41) Summary and Resources (duration 00:02:18) Note if you click on the link above and you do not see the play button to watch the course, you will have to login to the system and watch the course. I would like to throw a challenge to you – Can you watch both of the courses in a single day? If yes, once you are done watching the course on your Pluralsight Profile Page (here is my profile http://pluralsight.com/training/users/pinal-dave) you will get following badges. If you have already watched MySQL Fundamental Part 1, you can qualify by just watching MySQL Fundamental Part 2. Just send me the link to your profile and I will publish your name on this blog. For the first five people who send me email at Pinal at sqlauthority.com; I might have something cool as a giveaway as well. Watch the teaser of MySQL course.

  • SQL Authority News – Presenting at SQL Bangalore on May 3, 2014 – Performing an Effective Presentation

    - by Pinal Dave
    SQL Bangalore is a wonderful community and we always have a great response when we present on technology. It is SQL User Group and we discuss everything SQL there. This month we have SQL Server 2014 theme and we are going to have a community launch on this subject. We have the best of the best speakers presenting on SQL Server 2014 technology. Looking at the whole line of celebrity speakers, I have decided not to present on SQL Server. I will be presenting on the performance tuning subject, but with the twist of soft skills. I will be presenting on “Performing an Effective Presentation“. Trust me, you do not want to miss this presentation, I will be presenting on how to present effectively when presenting SQL Server topics. What this session will NOT have I personally believe that we all are good presenters most of the time. We can all easily call out if someone is bad presenter. There is no point talking about basics like bigger bullet points, talk loudly, talk with confidence, use better analogies etc. In simple words – this is not going to some philosophy session and boring notes. What this session will have Well, this session will tell stories of my life. It will tell how we can present about technology and SQL Server with the help of stories and personal experience. I am going to tell stories about two legends  who have inspired me. Right after that we will be doing two exercises together where we will learn quickly and effectively, how to become better speaker – instantly! There is no video recording of this session. If you want to get resources from this session, please sign up my newsletter at http://bit.ly/sqllearn Here are few of the slides from this presentation: Here is the details about the event and location Venue:Microsoft Corporation, Signature Building,Embassy Golf Links Business Park, Intermediate Ring Road, Domlur, Bangalore – 560071 The agenda is amazing – we have top line SQL Speakers.

  • Getting Started with Puppet on Oracle Solaris 11

    - by Glynn Foster
    One of the exciting enhancements with Oracle Solaris 11.2 has been the introduction of Puppet. While upstream Puppet did have some rudimentary support for Oracle Solaris 11, Drew Fisher and Ginnie Wray worked tirelessly to add enhance the Oracle Solaris Puppet offering. We've talked to customers over the past few years and asked them what their problems were and what technologies they were using, particularly for configuration management. Puppet came up time and time again, and it made a huge amount of sense bringing it as a 1st class citizen in the Oracle Solaris platform. So what is Puppet, and why is it useful? To quote from PuppetLabs, the guys who are responsible for creating Puppet: Puppet is a declarative, model-based approach to IT automation, helping you manage infrastructure throughout its lifecycle, from provisioning and configuration to orchestration and reporting. Using Puppet, you can easily automate repetitive tasks, quickly deploy critical applications, and proactively manage change, scaling from 10s of servers to 1000s, on-premise or in the cloud. What's more, with Puppet support for Oracle Solaris, administrators can now manage a completely heterogeneous data center from a single or series of Puppet masters. Better still, it's an excellent tool when combined with our new compliance framework to ensure you're meeting your compliance regulations. We're not stopping there of course, and we'll enhance our offerings over time, and work with PuppetLabs to get some of this support upstream (or into the Puppet Forge). So if you've heard some of the buzz around Puppet and never quite got started, and have some Oracle Solaris real estate that you'd love to manage, check out the Getting Started with Puppet on Oracle Solaris 11 guide.

  • Oracle Solaris at the OpenStack Summit in Atlanta

    - by Glynn Foster
    I had the fortune of attending my 2nd OpenStack summit in Atlanta a few weeks ago and it turned out to be a really excellent event. Oracle had many folks there this time around across a variety of different engineering teams - Oracle Solaris, Oracle ZFSSA, Oracle Linux, Oracle VM and more. Really great to see continuing momentum behind the project and we're very happy to be involved. Here's a list of the highlights that I had during the summit: The operators track was a really excellent addition, with a chance for users/administrators to voice their opinions based on experiences. Really good to hear how OpenStack is making businesses more agile, but also equally good to hear about some of the continuing frustrations they have (fortunately many of them are new and being addressed). Seeing this discussion morph into a "Win the enterprise" working group is also very pleasing. Enjoyed Troy Toman's keynote (Rackspace) about designing a planet scale cloud OS and the interoperability challenges ahead of us. I've been following some of the discussion around DefCore for a bit and while I have some concerns, I think it's mostly heading in the right direction. Certainly seems like there's a balance to strike to ensure that this effects the OpenStack vendors in such a way as to avoid negatively impacting our end users. Also enjoyed Toby Ford's keynote (AT&T) about his desire for a NVF (Network Function Virtualization) architecture. What really resonated was also his desire for OpenStack to start addressing the typical enterprise workload, being less like cattle and more like pets. The design summit was, as per usual, pretty intense for - definitely would get more value from these if I knew the code base a little better. Nevertheless, attended some really great sessions and got a better feeling of the roadmap for Juno. Markus Flierl gave a great presentation (see below) at the demo theatre for what we're doing with OpenStack on Oracle Solaris (and more widely at Oracle across different products). Based on the discussions that we had at the Oracle booth, there's a huge amount of interest there and we talked to some great customers during the week about their thoughts and directions in this respect. Undoubtedly Atlanta had some really good food. Highlights were the smoked ribs and brisket and the SweetWater brewing company. That said, I also loved the fried chicken, fried green tomatoes and collared greens, and wonderful hosting of "big momma" at Pitty Pat's Porch. Couldn't quite bring myself to eat biscuits and gravy in the morning though. Visiting the World of Coca-Cola just before flying out. A total brain washing exercise, but very enjoyable. And very much liked Beverly (contrary to many other opinions on the internet) - but then again, I'd happily drink tonic water every day of the year... Looking forward to Paris in November!

  • Harry Foxwell talks about "Oracle Solaris 11 System Administration: The Complete Reference"

    - by Glynn Foster
    In a previous blog entry, New Oracle Solaris 11 Administration book, I blogged about the fact that a new book has been written to provide an excellent resource for administrators starting to learn some of the new features in Oracle Solaris 11. Despite an extensive set of online resources from the Oracle Technology Network, it's also useful to have something in the bookshelf that you can quickly refer to - and Harry Foxwell and his team of co-authors have done just that. Check out the video below where Harry goes into detail about why the book was written, details about the target audience, and what he's excited about in Oracle Solaris 11. Best of all though, is the fact that this is a brilliant book for any inspiring Linux administrator who wants to start getting to know the Oracle Solaris operating system a little better.

  • A view from the call center for the Nashville Flood telethon

    - by Rob Foster
    I want to break away from my usual topic of something technical and talk about what I experienced tonight while working in the call center for the Nashville Flood telethon, which was broadcast on WSMV, CNN, and The Weather Channel.  We started receiving calls about 7pm local time and to be honest, I had no idea what to expect when going into this.  I mean, I'm a pretty good talker, but this is different...We had a good script of what to say and how we were supposed to say it, as well as paper forms and pens that we used to collect information from people who wanted to donate their money to help.  I took my first few calls pretty easily and it went pretty quick and easy.  Everyone was upbeat and happy to be in the call center as well as people happy to be donating money. Pizza, snacks, and soft drinks were flowing well.  Everyone is smiling and happy.  :) About 3 or 4 calls into my night, I got a call from a lady that had lost 2 family members in West Nashville who drowned in the floods.  She was crying when she called and I of course tried to console her.  She told me how bad her situation was, losing family members and much of her neighborhood.  After all this, she still just wanted to help other people.  She was donating all the money that she could to the telethon and I want to share a direct quote from her: "I want to donate this instead of buying flowers for my family members' funeral because people out there need help.". Please let me pause while I get myself together <again>.  That caught me so off guard (and still does). I had kids calling wanting to donate their allowance, open their piggy banks, whatever they could do.  These are kids.  Kids not much older than my boys.  Kids who should be focused on buying the next cool video game or toy or whatever but wanted to do something.  Everyone just seemed to want to help. I took calls from as far away as British Columbia as well and pretty much coast to coast.  how cool is that? Yet another thing that caught me off guard.  This kind lady that called from British Columbia told me how much she loved visiting Nashville and just hated to see this happen.  I belive that she said that she will be attending the CMA Fest this year too.  I was sure to tell her not to cancel her plans!  :) It felt like every call I took (and I took A LOT, as did everyone else) was very personal and heartfelt.  I've never had the privelage to do anything like this and fell lucky to have been able to help out with answering phones and logging donations.  Nashville will bounce back very quickly, people are out there day and night helping each other, and the spirits are very high here.  I hope that one day, my kids read this blog and better understand who they are, where they come from, and what the human spirt is and can be.  I love this city, I love the people here, I love the culture and even more than ever am proud to say that this is me.  This is us.  We are Nashville!

  • BPM 11g - Dynamic Task Assignment with Multi-level Organization Units

    - by Mark Foster
    I've seen several requirements to have a more granular level of task assignment in BPM 11g based on some value in the data passed to the process. Parametric Roles is normally the first port of call to try to satisfy this requirement, but in this blog we will show how a lot of use-cases can be satisfied by the easier to implement and flexible Organization Unit. The Use-Case Task assignment is to an approval group containing several users. At runtime, a location value in the input data determines which of the particular users the task is ultimately assigned to. In this case we use the Demo Community referenced in the SOA Admin Guide, and specifically the "LoanAnalyticGroup" which contains three users; "szweig", "mmitch" & "fkafka". In our scenario we would like to assign a task to "szweig" if the input data specifies that the location is "JapanCentral", to "fkafka" if the location is "JapanNorth" and to "mmitch" if "JapanSouth", and to all of them if the location is "Japan" i.e....   The Process Simple one human task process.... In the output data association of the "Start" activity we need to set the value of the "Organization Unit" predefined variable based on the input data (note that the  predefined variables can only be set on output data associations)....  ...and in the output data association of the human activity we will reset the "Organization Unit" to empty, always good practice to ensure that the Organization Unit will not be used for any subsequent human activities for which we do not require it.... Set Up the Organization Unit  Log in to the BPM Workspace with an administrator user (weblogic/welcome1 in our case) and choose the "Administration" option. Within "Roles" assign the "ProcessOwner" swim-lane for our process to "LoanAnalyticGroup".... Within "Organization Units" we can model our organization.... "Root Organization Unit" as "Japan" and "Child Organization Unit" as "Central", "South" & "North" as shown. As described previously, add user "szweig" to "Central", "mmitch" to "South" and "fkafka" to "North"....   Test the Process Invalid Data  First let us test with invalid data in the input to see what the consequences are, here we use "X" as input.... ...and looking at the instance we can see it has errored.... Organization Unit Root Level Assignment  Now let us see what happens if we have "Japan" in the input data.... ...looking in the "flow trace" we can see that the task has been assigned....  ... but who has the task been assigned to ? Let us look in the BPM Workspace for user "szweig"....  ...and for "mmitch"....  ... and for "fkafka"....  ...so we can see that with an Organization Unit at "Root" level we have successfully assigned the task to all users. Organization Unit Child Level Assignment  Now let us test with "Japan/North" in the input data.... ...and looking in "fkafka" workspace we see the task has been assigned, remember, he was associated with "JapanNorth"....   ... but what about the workspace of "szweig"....  ...no tasks assigned, neither has "mmitch", just as we expected. Summary  We have seen in this blog how to easily implement multi-level dynamic task routing using Organization Units, a common use-case and a simpler solution than Parametric Roles.
