Trace Files -- 1 : Generating SQL Traces (own session)

Hemant K Chitale - Sun, 2015-09-20 08:18
Beginning a new series of posts on Trace Files.

An SQL Trace captures SQL statements (including recursive SQL calls -- e.g. data dictionary lookups or triggers being executed, which are not "directly" visible to the client or explicitly executed by the client).   Optionally, it can capture Wait Events and Binds.

Tracing for Wait Events allows us to capture the Wait Events that occur within the duration of an SQL call.  Tracing for Binds allows us to capture the Bind Values that were passed by the Client (where the SQL code uses Bind Variables instead of Literals)

Here are a few methods to get the SQL Trace for one's own session (whether interactively in sqlplus or programmatically through any other client)

EVENT 10046
This is not recommended by Oracle although it seems to be widely in use.  Use with extreme caution as specifying the wrong event number or level when issuing an ALTER SESSION command can result in unpredictable behaviour and possible corruption.  I include it here not as a recommendation but only because I anticipate that I will be asked about this.  I do NOT recommend using this method.  (Levels 16 and 32 have not been tested by me)

This method is used with either of these commands :

ALTER SESSION SET EVENTS '10046 trace name context forever, level 1'; -- for the same behaviour as SQL_TRACE=TRUE
ALTER SESSION SET EVENTS '10046 trace name context forever, level 4'; -- for tracing Binds with the SQLs
ALTER SESSION SET EVENTS '10046 trace name context forever, level 8'; -- for tracing Wait Events with the SQLs
ALTER SESSION SET EVENTS '10046 trace name context forever, level 12'; -- for tracing both Binds and Wait Events with the SQLs
ALTER SESSION SET EVENTS '10046 trace name context forever, level 16'; -- to dump STAT lines for each execution
ALTER SESSION SET EVENTS '10046 trace name context forever, level 32'; -- never dump execution statistics

After executing the desired SQLs to be traced, tracing is disabled with :

ALTER SESSION SET EVENTS '10046 trace name context off';
(I have updated the "context forever, level 0" to "context off"  which is the correct method.  This just shows that I haven't used this method of tracing for a long time !)

The instance / session parameter SQL_TRACE is the oldest method and may still be in use although it has been deprecated in recent versions.

This is done with the SQL command :


After executing the SQLs that need to be traced, it is then disabled with the SQL command :


This PLSQL procedure is the proper alternative to setting the parameter SQL_TRACE.

This is done with


The EXEC call allows the PLSQL procedure to be executed from the command line.

After executing the SQLs that need to be traced, it is then disabled with the command :


This PLSQL procedure is the preferred method.  It also offers switches to enable/disable tracing for Wait Events and Binds separately.

This is done with


Thus, the switch for tracing Waits is active but tracing Binds is deactivated.  (Optionally, Binds could also be traced with the binds switch set to TRUE).

After executing the target SQLs in the session, it is then disabled with the command :


Thus, no flags need to be supplied to disable both Waits and Binds.

Site Maintenance (20th Sept 2015 22:00 GMT)

Tim Hall - Sat, 2015-09-19 01:30

DiagnosticsJust a quick heads-up about some work going on tomorrow on the website.

My hosting provider has decided my server needs to be put into a new rack, so somewhere after 22:00 GMT tomorrow (20th Sept 2015) the server will be switched off, moved to a new rack and switched on. They say the process should be complete within 4 hours. I’m hoping this is a massive overestimate. :)

If you are trying to use the site around that time and it’s not there, DON’T PANIC! I’ll be doing plenty of that for both of us. :)

ORA-01917: user or role 'PDB_DBA' does not exist

Pakistan's First Oracle Blog - Sat, 2015-09-19 00:42
I manually created a container database (CDB) in my Linux 6.4 based virutal machine. After creating it, I tried to create a pluggable database but got following error:

SQL> select instance_name,status from v$instance;

---------------- ------------
cdbtest          OPEN

1 row selected.

SQL> show con_name


SQL> select * from cdb_pdbs;

 202375680 LOGGING   NO  NO           2

So I tried with different options, but it always gave that error about PDB_DBA role. Searching the MOS, presented document.

This Document states that if we create a CDB manually we need to get from DBCA because we might have omit some options. CDB and PDB needs to be installed with all the options. I created CDB manually in first place because I had low disk space in my virtual machine, and I was intending to use all the options.

So if you get that error, the solution is to either create database through DBCA.

Tracing Data Lineage and Impact Analysis in Oracle Enterprise Metadata Management 12c

Rittman Mead Consulting - Fri, 2015-09-18 22:11

At the beginning of the year, I wrote a couple of posts about Oracle Enterprise Metadata Management, one about how to install the tool and another one explaining the harvesting (importing) and stitching (relating) processes. A lot of things have happened since then, including a new version of OEMM released on May with some nice features as HTML 5 support, a workflow for business glossary and including the concept of groups in security.

OEMM is the Oracle solution for data governance and lifecycle management.  “Data governance (DG) refers to the overall management of the availability, usability, integrity, and security of the data employed in an enterprise”. So, the process of knowing how my data is related, the integrity of it, who has access to which part of the data and with which application, from where people can access the data, defining the stewards of the data, etc are part of data governance.

To refresh the main concepts, the first thing that you have to do when you start working with OEMM is the harvesting or importing process. We import the metadata creating one model for each different metadata source. After the successful importing process, we need to create a configuration to relate all the required models.

One of the main features of OEMM is to perform Data Flow Lineage and Impact Analysis. Why is this so important? Because the typical problem that we face in IT is to understand how all the company data is related, what will happen if I modify one column in a source schema,  or how I can find out where a particular piece of data come from. In this post I will talk about these process which are exactly the same as in the previous version.

I created an environment where I installed the latest release of OEMM (, Oracle Database 12c that contains the source, staging and DW schemas and ODI 12c which is the ELT tool to load and transform the data into our DW schema. In addition I also have OBIEE 11g which repository is based on the DW schema and some OBI analyses to query the data. I imported all the metadata from these different sources and create a configuration that includes all the models created.


Data Impact Analysis

The process of Data Impact Analysis is to find out which data items in target database and/or applications are affected if we change one source object, like a column or a table or another source object.

There are many ways to start the tracing data impact process in OEMM. We can start the analysis impact process in OEMM from the model where the object belongs or from a diagram.

We can open the model from the repository panel or from the configuration Architecture diagram. Once the model is opened, select the object that you want to perform the impact analysis, right click on it, and select Trace Data Impact or Trace Lineage (Advanced) option. Either option opens the same dialog window.


Then, we need to choose between the model and the configuration as the scope for this impact analysis. The most common option is to select one configuration to see the consequences of a possible change in all the target models present in this configuration. Also we have the option to see the result in graphic or in text mode.

In our example, we are going to trace the data impact of the ORDERS table which is in the database source model and is the source for the fact table in the DW.

In the following picture, you will find the resulted diagram of the data impact analysis. In order to see the diagrams better in OEMM,  you can collapse the Properties windows at your right and press the Fit to Content button in the diagram menu.


There are plenty of interesting things that you can do from here. First, if you take a closer look you will see that the lines between the Orders Source and Order Staging as well as the ones from Orders Staging and Orders_DW are ticker than the ones that connect Orders_DW to the OBIEE Model. This means there are some ETL process in the middle of these connections. When we right click on one of these arrows and select Trace ETL details, a new tab is opened inside the configuration and will show the mappings involved and the operations (a JOIN in our example). Also if we expand the windows properties and select the JOIN element we can see its condition.


Coming back to the Data Impact diagram, you can select one particular object like a column and press the highlight path button to emphasise only a specific data flow. This is very useful when you have many objects in the diagram and you need to focus in some particular data path.


If you want to keep this diagram saved so you can come back easily to it, you can add a bookmark. You can create folders to organise your bookmarks and they will appear at the bottom left of the screen.




Tracing Data Lineage

The Trace Data Lineage process is to find the path from the source to the target object that you selected.

In OEMM, tracing data lineage is a very similar process to impact analysis. In fact, it uses the same dialog window but now you should select the Trace Data Lineage or Trace Lineage (Advanced) option. Again, either option opens the same dialog window.

In our example, we are going to use the Table View from a particular OBI Analysis. We will perform first the data lineage using the model as a scope and then run another one in the context of the configuration in order to make clear the differences between these two data lineages.

Once I have the OBIEE Model opened, I double-click the required analysis and the analysis with all its components (criteria and layout) will appear in the Metadata Browser. I will run first the data lineage based on the model.


Another tab is shown with the data lineage based on the model. You can select one measure for example and see the properties. It will show details as the expression or formula (if it is a calculated item) and the default aggregation. In the diagram appears three main objects (that can be collapsed or expanded as required), one that represents the physical layer in the OBI repository (rpd), another for the Presentation layer and finally the table view in the OBI Analysis.

As you probably realise by now, there are a lot of tabs and panels that appears as you open different objects and execute some tasks. The panels are collapsible and can be resized, so you will need to do this a lot in order to visualise what you want.


We are going to repeat the same process but now selecting the configuration that contains the OBIEE model. In this new diagram you will see where the data in the OBI Analysis is coming from and the relationship with the other models in the configuration including the ODI model and the different database schemas. You can expand or collapse the objects in the diagram, tracing ETL details, highlight the path and all the features that we’ve seen for the data impact diagram as it is the same diagram.


Another useful and new feature of this release is the quick find that allows you to search for specific words and show you a list of all the objects in the diagram that matches the search criteria. If you double-click in one of this results, the object will appear highlighted in the diagram.


Model Connection Overview

The Model Connection Overview diagram shows the connection of the objects inside a model. As its name suggests is just an overview of the connections. You cannot go deeper into the object details, but is useful to have a rough idea of the object relationship in a model.  In the next pictures you will see an example of he Model Connection diagram of the OBIEE model and the diagram for a particular mapping in the ODI model. You can also save it as a bookmark as the other diagrams.


And this is how you can perform data lineage and impact analysis in OEMM, analysing the relationships among your company data.

My Sales Journey: #3

Pythian Group - Fri, 2015-09-18 13:26


This week started off with the last on boarding session with the CEO himself. It was my favorite for many reasons. It was passionate the way it can be when you build something from nothing with blood, sweat and tears and it resonated with me having been down that path myself. You hear it in the tone of their voice and the pride in their eyes. That BORG (boarding of recruited gurus!) is the inspiration for today’s post. Here are my takeaways from Week 3:

To be effective in a sales role you need to speak like a CEO, learn your product inside out and when people listen to you they must hear how amazing your product/service is without you ever saying how amazing it is. Your passion will shine through by your demonstrated knowledge.

Outreach needs organization as it demands many different tasks to be done at once. It is a daunting task but I am sure it will get better as I learn how to get the best out of my day. I am lucky to have a set up that allows me focus like two big screens, headsets, phones and most of all a manager who is there to assist and actively involved to make sure I succeed.

Being flustered is normal! You know that moment when you are making calls and leaving voice messages and suddenly you get a live one! You mumble your way through it and think Wow! I could have been so much better. I had one of those moments this week and it made me go out and do research and find better questions to ask. I chalk it down to my learning curve and move on.

As a rookie, your team is your support structure. Again, lucky to be surrounded by people who collaborate, take the time to help out, craft email templates and show you how its done on the phone. Without all that this fish jumping into unknown waters would certainly drown.

It’s been a good week! Share this with your rookies or if you are rookie tell me how your week was. Looking forward to hearing from you.

The University As Ed Tech Startup: UMUC, Global Campus, Texas, and SNHU roll their own

Michael Feldstein - Fri, 2015-09-18 13:08

By Phil HillMore Posts (365)

Today the University of Maryland University Campus (UMUC) announced its plans to spin off their Office of Analytics into a separate for-profit ed tech company.

The University System of Maryland Board of Regents today approved a University of Maryland University College (UMUC) plan to spin off its Office of Analytics into a new company, HelioCampus, that will provide business intelligence products and services to universities nationwide. [snip]

The new company will provide a foundational analytics platform and data analysis services. This comprehensive offering will include all the tools needed to support or jumpstart an analytics program. HelioCampus will host a secure platform in the cloud that will include flexible data models and best-in-class visual analytics to accelerate analysis.

The technology will be complemented by a team of higher-education and business-intelligence experts. Each institution will be assigned a dedicated analyst that will partner with key stakeholders to interpret the data and highlight key trends.

The Chronicle quotes two UMUC execs – CIO Pete Young (staying at UMUC) and VP for Analytics Darren Catalano (leaving UMUC to become HelioCampus’ chief executive). It is worth noting, as Stephen deFilipo did on Twitter, that both Pete Young and Darren Catalano come from Rosetta Stone.

“The market as it currently stands has some very traditional software tools,” said Peter C. Young, UMUC’s senior vice president for analytics, planning, and technology. “You buy software licenses, you pay for very expensive implementation. Fundamentally, you’re doing your own thing.” [snip]

“We know what data is valuable and what data is not,” said Darren Catalano, UMUC’s vice president for analytics. Most colleges aren’t using their data effectively, he said, and the ability to understand your own data “is no longer optional in higher education.”

This story, however, is important beyond just UMUC and HelioCampus, as it is part of a growing trend for universities to act as ed tech startup. This can be done either with a for-profit spinoff company or with an internal incubator.

SNHU and Motivis Learning

SNHU, the university best known for its College for America competency-based education (CBE) program, spun off its learning platform into a separate company. As reported by Inside Higher Ed in September 2014:

Southern New Hampshire University, seeing an opening in the market for a learning management system designed around competency-based education, is spinning off the custom-made system it built to support College for America.

Before College for America launched in January 2013, the university considered building a platform to support the competency-based education subsidiary on top of the learning management system used on campus, Blackboard Learn. The university instead picked Canvas, created by Instructure, but after only a couple of months, “we decided we needed to build our own,” said Paul J. LeBlanc, president of the university. [snip]

On Oct. 1, one year after the system went live at College for America, the university is spinning it off as Motivis Learning and writing the for-profit subsidiary a $7 million check. In its first phase, LeBlanc said, the company will further develop its platform based on how other institutions are approaching competency-based learning.

University of Texas and UTx / TEx

The University of Texas System and its Institute for Transformational Learning (ITL), with a $50 million kickstart in 2012, created as an office leading a series of ed tech initiatives. One of UTx’s signature initiatives is a “next-generation educational ecosystem” called TEx that supports the U Texas CBE programs. From Inside Higher Ed in November 2014:

The institute is building its own competency-based platform, but is drawing pieces from several vendors to put it together.

Marni Baker Stein, the institute’s chief innovation officer, described a “stack” of elements, dubbed TEx, for Total Educational Experience. TEx will include customer relationship software, adaptive technology, a “cross-contextual” user interface and mobile technology. RealizeIt from CCKF, Big Tomorrow and Robots and Pencils are some of the firms the system has tapped.

CSU Global Campus

Like UMUC, Colorado State University System’s online arm – the Global Campus – is also in the middle of creating a spin-off for-profit company partially based on analytics. They have not made public the selected name of the venture, so their internal documents list it as “NewCo”. The February 2015 board of governors’ meeting described the goals.

President Takeda-Tinker explained the concept of NewCo as a tech transfer entity to leverage CSU- Global Campus’ expertise to serve market needs. Services would be offered to other educational institutions and business sectors, and would include consulting, technology licenses, and outsource services. NewCo would benefit the CSU System and CSU-Global Campus in multiple ways in planning for future financial viability. The suggestion was made to provide examples of Colorado tech transfer entities in the business plan.

From what I can read in the subsequent meeting notes, CSU has approved the creation of the entity, selected (but not made public) the name, and are currently setting it up as legal entity owned by the CSU Foundation. The key elements of technology are portals (faculty, staff, and student) as well as faculty management system. This last one is interesting, based on systems to verify how much time instructors actually spend on each course, what their level of interaction is with students, and other monitoring software that can be controversial outside of large online programs.

There are more details in this slide presentation that was part of the December 2014 meeting.

More to Come

Are these efforts paving the way for universities who know their own business to create profitable ed tech and services offerings based on unique insights into how schools really work, or are they vehicles for star-struck administrators seeing glory and easy revenues? Or both? Only time will tell, but I would expect to see more announcements of a similar nature over the next year or two. Watch for more coverage here.

How to View Field Service Task Information

Joshua Solomin - Fri, 2015-09-18 11:23
If you have a Service Request (SR) that requires hardware replacement or a visit from a hardware support engineer, your SR will have "Field Service Tasks" associated with it. These tasks can be viewed in My Oracle Support as outlined below.

NOTE: If you have Services or MICROS products that require part replacement, you will need to switch to the My Oracle Support Portal to view the field tasks in the SR. (reference A).

1. In My Oracle Support, locate the SR region on the Dashboard or click the Service Request tab and locate your Service Request (reference B).

2. Open the desired Service Request, then click on the Field Service Tasks link (reference C) on the right hand side of the screen under the Summary section. A list of associated Tasks will display (reference D).

3. Click on the desired Task Number for details about that Task. The Task information is displayed and can be sorted using the Sort By drop down menu (reference E).

For additional tips on Service Request management view the My Oracle Support 'How-to' Series (Doc ID 1544005.2).

Android Users, You Need Vysor

Oracle AppsLab - Fri, 2015-09-18 10:14

Despite the amount of iOS and Apple Watch chatter here lately, we still have a dedicated Android user base on the team, including me.

If you read here, you’ll know that projecting an Android device screen to an audience has always been important for us, and usually we have more than one screen to project. Over the years, I’ve used several tools for this BBQScreenAndroid Screen Monitor and lately, Chromecast’s screen mirroring feature, which is handy because it cuts out the laptop middleman.

Enter a Chrome app called Vysor, created by Android luminary, Koushik Dutta, better know as koush.


You may remember him from such projects as CyanogenMod, AllCast, Helium, ROM Manager, etc. He’s kind of a big deal in the Android modding community because he’s constantly filling Android gaps and improving the Android experience.

And Vysor doesn’t disappoint. Just install the Chrome app from the Chrome Web Store, set the developer options on your Android device and plug it into your machine.

Vysor opens your device’s screen, and sit down for this one, allows you to control it via mouse and keyboard.vysor1You read that right. This is a huge feature that none of the other options I’ve tried offer.

For a full how-to, read Lifehacker’s post.

As an aside, Chrome apps are the bee’s knees. They are truly cross-platform, can run in their own windows outside Chrome and can run when Chrome itself is closed. Seriously, I can quit Chrome and launch the Vysor app on its own. I just did this on OS X and again on Ubuntu.

Did you know that? Although I did, and I shared the enthusiasm of the tech press back in late 2013, I had forgotten. Google hasn’t done a very good job promoting this awesome capability of the Chrome ecosystem.

Not to wander too far off topic, but it is a shame to see Chrome take a back seat to Android when the two are equally useful.

Moving on, Vysor is in beta. It works really well with one device from what I’ve seen. However, once you get two devices connected, it gets confused.


I might have something set wrong, or maybe it’s that annoying Android File Transfer app that’s required (is it still?) for OS X.

Might be user error.

Anyway, if you’re an Android user, check out Vysor. It’s awesome.

Taking a Composition Exam

Chris Foot - Fri, 2015-09-18 05:00

You may perhaps often possibly be requested within higher education to look at composition examinations. In some techniques, a similar guidelines regarding composing good out-of-class works apply to producing good in-class works at the same time. For example, the two sorts of works are definitely more prosperous if you consider your function, crowd along with facts; whenever you develop a thesis together with assist; if you verify your assertions together with facts; when you guidebook your current audience with changes, and so forth.

However, there are many variances to keep in mind since you put together to publish. The most important the first is the point intended for composing. Commonly anyone create an investigation report, by way of example, to learn more regarding ones decided on matter; on the other hand, you compose article examinations to show the know-how. You aren’t merely offerring facts, and also indicating for a audience–the examiner–that you could have mastered the information which enables it to assist this.

Mind-blowing physical violence is just not premeditated. If your kid requires as well as failures the family auto, for example, the father may perhaps burst and conquer him. Coercive violence, conversely, will be sharp along with purposive; they have the purpose of producing complying as well as conformity.

SANGAM15 – See you there!

Tim Hall - Fri, 2015-09-18 04:31

I mentioned my Oracle OpenWorld 2015 trip in a previous post. Yesterday evening I picked up my passport with my lovely new India visa in it!

The talks are written. The flights are booked. The hotel is booked. I have a visa. So that’s me sorted for SANGAM15 in November! :)

It’s going to be a rather hectic few days. I fly out, do the 2 day conference, then fly straight home. It looks like I will be in aeroplanes and airports longer than I will actually be in India. :)

If you are coming along to the conference, be sure to come and say hello. :)

Selling Books on Amazon vs. Intelivideo

Bradley Brown - Thu, 2015-09-17 20:44
For the last couple of years I've heard that publishers don't like selling their books through Amazon.  The way I heard it described sounded like Amazon was forcing (or pushing) you to sell books for under $10.  It's actually pretty complicated as to how their pricing works, so I've attempted to simplify for you here.  If you want the details, you can read more here:

Basically you have to pick which plan you’re on.  The 35% or 70% royalty plan.  At first glance, you would ask - why would anyone pick the 35% royalty plan?  Let's see, you do all of the research, write the book, take a book through 5 edits and get it to the point of publishing and Amazon is going to keep 35 "or" 70% of the revenue generated?  Logically who would say they only want to keep 35%?  It's more complicated - i.e. strings are attached to each choice.

If you pick the 70% royalty plan, you keep as much as 70% (minus delivery costs and with about 100 other rules) of whatever they sell it for.  But according to the small print, on a number of your sales, you’ll actually keep 35% of whatever they sell it for.  Here's the real kicker - if you want to keep 70% (minus delivery costs, VAT, etc), they force you to set the list price to $2.99 to $9.99 AND by the way they will keep 65% if they sell it in other countries, etc.  If you choose the 35% royalty plan (keep in mind, they are are keeping 65%), you can set the price between $2.99 and $200.  You can sell it for less than $2.99 (i.e. down to $.99) if you have a small book (i.e. less than 10Mb footprint).  They also say that the list price must be at least 20% below the lowest physical list price for the physical book.  Wow - SO many rules!

So Amazon charges (keeps) 30% (minus delivery costs) to 65% (and it’s usually this amount) and has minimum and maximum prices you can charge and a lot of rules AND it’s Amazon’s customer (not yours).

The 2 pricing options are explained (and tough to understand) here:

And their FAQ is here:

We're soon to release (secure) eBook functionality at Intelivideo.  So how does it work?  If you pick the Pro Plan, you keep 85% of the revenue and you can set the price to whatever price you want.  We have some other fine print, but overall I can assure you that our pricing is WAY better than Amazon's offer - and it's your customer.  You can sell them more products.  You can do promotions to them.  You can upsell them.  I'm shocked by Amazon's model and now understand the frustration others have!
