• Upgrades in 5 Easy Pieces

  - by Anne R.

  Even though there are a few select tasks that I have to do once or twice a year, I can’t remember how to do them! Or where to find the bits and pieces to complete the task. So I love it when someone consolidates everything under one spot. That’s what the CRM On Demand team has done with the upgrade information. Specifically, they have: Provided a “one-stop” area for managing upgrades at your company. Broken down the upgrade process into 5 (yes, 5) steps. Explained when and how to perform each step with dates specific to your pod. Included details about each step, visible by expanding the step. Translated the steps into 11 languages. Added a list of release-specific resources with links from the page. Now, just head for the Training and Support portal, click the Release Info tab, and walk through the “5 Essential Steps to a Successful Upgrade.” Before you continue, though, select your language from the drop-down list on the Release Info page. CRM On Demand now has the upgrade steps translated into 11 languages. On the Step page, you can expand each section in sequence and follow the more detailed instructions that appear. This will ensure that you’ve covered all your bases for each upgrade. Here’s a shortened version of the information that you’ll find: 1. Verify your Primary Contact Information. Have you checked your primary contact information to make sure you’re being notified of all upgrade information? Or do you want more users to receive upgrade announcements? This section provides you with the navigation path to do that in CRM On Demand. 2. Review your Key Upgrade Dates. If you expand this step, a nice table appears with your critical dates for the various milestones. IMPORTANT: When your CRM On Demand pod has been officially added to the upgrade schedule, closer to the release date itself, this table will display your specific timetable. 3. Migrate your Customizations from the Staging Environment before the Snapshot Date. Oracle refreshes the Staging data with a copy of your Production data made on the Production Snapshot Date. So this section lists considerations relevant to this step. It also reminds you of the 2-week period when you should not be making any changes in your Staging environment.   4. Conduct your Upgrade Validation on the Staging Environment. When the Customer Validation Testing period begins, you need to log in to your Staging Environment to validate that your key business processes and customizations continue to behave as expected. If your company utilizes Web Services, Web Links, Web Applets or Workflow, focus on testing these first. You generally have about two weeks for testing. If you run into problems during this time, follow the instructions shown in this section for logging a service request. It describes exactly how to fill out the fields in the SR for the fastest resolution. 5. Conduct "White Glove" Testing in your Upgraded Production Environment. Before users start using the upgrade, you should access a few tabs and reports. Doing this actually warms up the cache so that frequently used pages and reports will come up at normal speed on Monday morning, when users log in to the upgraded system. Resources listed under this step help you in further preparing for the upgrade. Now there’s also a new Documentation section on the right with links to these release-specific resources.   Very nice, I commented, when discussing these improvements with the “responsible party.” She confirmed that, yes, they tried to consolidate the upgrade information, translate it for better communication, simplify it into 5 easy pieces, and drive admins responsible for handling upgrades to this one site instead of sending out elaborate emails. Yes, I just love it when someone practically reaches out and holds my hand through a process. Next best thing to a wizard!

• Master Data Management for Location Data - Oracle Site Hub

  - by david.butler(at)oracle.com

  Most MDM discussions cover key domains such as customer, supplier, product, service, and reference data. It is usually understood that these domains have complex structures and hundreds if not thousands of attributes that need governing. Location, on the other hand, strikes most people as address data. How hard can that be? But for many industries, locations are complex, and site information is critical to efficient operations and relevant analytics. Retail stores and malls, bank branches, construction sites come to mind. But one of the best industries for illustrating the power of a site mastering application is Oil & Gas.   Oracle's Master Data Management solution for location data is the Oracle Site Hub. It is a location mastering solution that enables organizations to centralize site and location specific information from heterogeneous systems, creating a single view of site information that can be leveraged across all functional departments and analytical systems.   Let's take a look at the location entities the Oracle Site Hub can manage for the Oil & Gas industry: organizations, property, land, buildings, roads, oilfield, service center, inventory site, real estate, facilities, refineries, storage tanks, vendor locations, businesses, assets; project site, area, well, basin, pipelines, critical infrastructure, offshore platform, compressor station, gas station, etc. Any site can be classified into multiple hierarchies, like organizational hierarchy, operational hierarchy, geographic hierarchy, divisional hierarchies and so on. Any site can also be associated to multiple clusters, i.e. collections of sites, and these can be used as a foundation for driving reporting, analysis, organize daily work, etc. Hierarchies can also be used to model entities which are structured or non-structured collections of nodes, like for example routes, pipelines and more. The User Defined Attribute Framework provides the needed infrastructure to add single row attributes groups like well base attributes (well IDs, well type, well structure and key characterizing measures, and more) and well geometry, and multi row attribute groups like well applications, permits, production data, activities, operations, logs, treatments, tests, drills, treatments, and KPIs. Site Hub can also model areas, lands, fields, basins, pools, platforms, eco-zones, and stratigraphic layers as specific sites, tracking their base attributes, aliases, descriptions, subcomponents and more. Midstream entities (pipelines, logistic sites, pump stations) and downstream entities (cylinders, tanks, inventories, meters, partner's sites, routes, facilities, gas stations, and competitor sites) can also be easily modeled, together with their specific attributes and relationships. Site Hub can store any type of unstructured data associated to a site. This could be stored directly or on an external content management solution, like Oracle Universal Content Management. Considering a well, for example, Site Hub can store any relevant associated multimedia file such as: CAD drawings of the well profile, structure and/or parts, engineering documents, contracts, applications, permits, logs, pictures, photos, videos and more. For any site entity, Site Hub can associate all the related assets and equipments at the site, as well as all relationships between sites, between a site and multiple parties, and between a site and any purchasable or sellable item, over time. Items can be equipment, instruments, facilities, services, products, production entities, production facilities (pipelines, batteries, compressor stations, gas plants, meters, separators, etc.), support facilities (rigs, roads, transmission or radio towers, airstrips, etc.), supplier products and services, catalogs, and more. Items can just be associated to sites using standard Site Hub features, or they can be fully mastered by implementing Oracle Product Hub. Site locations (addresses or geographical coordinates) are also managed with out-of-the-box address geo-coding capabilities coupled with Google Maps integration to deliver powerful mapping capabilities and spatial data analysis. Locations can be shared between different sites. Centered on the site location, any site can also have associated areas. Site Hub can master any site location specific information, like for example cadastral, ownership, jurisdictional, geological, seismic and more, and any site-centric area specific information, like for example economical, political, risk, weather, logistic, traffic information and more. Now if anyone ever asks you why locations need MDM, think about how all these Oil & Gas entities and attributes would translate into your business locations. To learn more about Oracle's full MDM solution for the digital oil field, here is a link to Roberto Negro's outstanding whitepaper: Oracle Site Master Data Management for mastering wells and other PPDM entities in a digital oilfield context

• Data Security Through Structure, Procedures, Policies, and Governance

  Security Structure and Procedures One of the easiest ways to implement security is through the use of structure, in particular the structure in which data is stored. The preferred method for this through the use of User Roles, these Roles allow for specific access to be granted based on what role a user plays in relation to the data that they are manipulating. Typical data access actions are defined by the CRUD Principle. CRUD Principle: Create New Data Read Existing Data Update Existing Data Delete Existing Data Based on the actions assigned to a role assigned, User can manipulate data as they need to preform daily business operations.  An example of this can be seen in a hospital where doctors have been assigned Create, Read, Update, and Delete access to their patient’s prescriptions so that a doctor can prescribe and adjust any existing prescriptions as necessary. However, a nurse will only have Read access on the patient’s prescriptions so that they will know what medicines to give to the patients. If you notice, they do not have access to prescribe new prescriptions, update or delete existing prescriptions because only the patient’s doctor has access to preform those actions. With User Roles comes responsibility, companies need to constantly monitor data access to ensure that the proper roles have the most appropriate access levels to ensure users are not exposed to inappropriate data.  In addition this also protects rouge employees from gaining access to critical business information that could be destroyed, altered or stolen. It is important that all data access is monitored because of this threat. Security Governance Current Data Governance laws regarding security Health Insurance Portability and Accountability Act (HIPAA) Sarbanes-Oxley Act Database Breach Notification Act The US Department of Health and Human Services defines HIIPAA as a Privacy Rule. This legislation protects the privacy of individually identifiable health information. Currently, HIPAA   sets the national standards for securing electronically protected health records. Additionally, its confidentiality provisions protect identifiable information being used to analyze patient safety events and improve patient safety. In 2002 after the wake of the Enron and World Com Financial scandals Senator Paul Sarbanes and Representative Michael Oxley lead the creation of the Sarbanes-Oxley Act. This act administered by the Securities and Exchange Commission (SEC) dramatically altered corporate financial practices and data governance. In addition, it also set specific deadlines for compliance. The Sarbanes-Oxley is not a set of standard business rules and does not specify how a company should retain its records; In fact, this act outlines which pieces of data are to be stored as well as the storage duration. The Database Breach Notification Act requires companies, in the event of a data breach containing personally identifiable information, to notify all California residents whose information was stored on the compromised system at the time of the event, according to Gregory Manter. He further explains that this act is only California legislation. However, it does affect “any person or business that conducts business in California, and that owns or licenses computerized data that includes personal information,” regardless of where the compromised data is located.  This will force any business that maintains at least limited interactions with California residents will find themselves subject to the Act’s provisions. Security Policies All companies must work in accordance with the appropriate city, county, state, and federal laws. One way to ensure that a company is legally compliant is to enforce security policies that adhere to the appropriate legislation in their area or areas that they service. These types of polices need to be mandated by a company’s Security Officer. For smaller companies, these policies need to come from executives, Directors, and Owners.

• Conflict Minerals - Design to Compliance

  - by C. Chadwick

  Dr. Christina  Schröder - Principal PLM Consultant, Enterprise PLM Solutions EMEA What does the Conflict Minerals regulation mean? Conflict Minerals has recently become a new buzz word in the manufacturing industry, particularly in electronics and medical devices. Known as the "Dodd-Frank Section 1502", this regulation requires SEC listed companies to declare the origin of certain minerals by 2014. The intention is to reduce the use of tantalum, tungsten, tin, and gold which originate from mines in the Democratic Republic of Congo (DRC) and adjoining countries that are controlled by violent armed militia abusing human rights. Manufacturers now request information from their suppliers to see if their raw materials are sourced from this region and which smelters are used to extract the metals from the minerals. A standardized questionnaire has been developed for this purpose (download and further information). Soon, even companies which are not directly affected by the Conflict Minerals legislation will have to collect and maintain this information since their customers will request the data from their suppliers. Furthermore, it is expected that the public opinion and consumer interests will force manufacturers to avoid the use of metals with questionable origin. Impact for existing products Several departments are involved in the process of collecting data and providing conflict minerals compliance information. For already marketed products, purchasing typically requests Conflict Minerals declarations from the suppliers. In order to address requests from customers, technical operations or product management are usually responsible for keeping track of all parts, raw materials and their suppliers so that the required information can be provided. For complex BOMs, it is very tedious to maintain complete, accurate, up-to-date, and traceable data. Any product change or new supplier can, in addition to all other implications, have an effect on the Conflict Minerals compliance status. Influence on product development  It makes sense to consider compliance early in the planning and design of new products. Companies should evaluate which metals are needed or contained in supplier parts and if these could originate from problematic sources. The answer influences the cost and risk analysis during the development. If it is known early on that a part could be non-compliant with respect to Conflict Minerals, alternatives can be evaluated and thus costly changes at a later stage can be avoided. Integrated compliance management  Ideally, compliance data for Conflict Minerals, but also for other regulations like REACH and RoHS, should be managed in an integrated supply chain system. The compliance status is directly visible across the entire BOM at any part level and for the finished product. If data is missing, a request to the supplier can be triggered right away without having to switch to another system. The entire process, from identification of the relevant parts, requesting information, handling responses, data entry, to compliance calculation is fully covered end-to-end while being transparent for all stakeholders. Agile PLM Product Governance and Compliance (PG&C) The PG&C module extends Agile PLM with exactly this integrated functionality. As with the entire Agile product suite, PG&C can be configured according to customer requirements: data fields, attributes, workflows, routing, notifications, and permissions, etc… can be quickly and easily tailored to a customer’s needs. Optionally, external databases can be interfaced to query commercially available sources of Conflict Minerals declarations which obviates the need for a separate supplier request in many cases. Suppliers can access the system directly for data entry through a special portal. The responses to the standard EICC-GeSI questionnaire can be imported by the supplier or internally. Manual data entry is also supported. A set of compliance-specific dashboards and reports complement the functionality Conclusion  The increasing number of product compliance regulations, for which Conflict Minerals is just one example, requires companies to implement an efficient data and process management in this area. Consumer awareness in this matter increases as well so that an integrated system from development to production also provides a competitive advantage.

• Scenarios for Throwing Exceptions

  - by Joe Mayo

  I recently came across a situation where someone had an opinion that differed from mine of when an exception should be thrown. This particular case was an issue opened on LINQ to Twitter for an Exception on EndSession.  The premise of the issue was that the poster didn’t feel an exception should be raised, regardless of authentication status.  As first, this sounded like a valid point.  However, I went back to review my code and decided not to make any changes. Here's my rationale: 1. The exception doesn’t occur if the user is authenticated when EndAccountSession is called. 2. The exception does occur if the user is not authenticated when EndAccountSession is called. 3. The exception represents the fact that EndAccountSession is not able to fulfill its intended purpose - to end the session.  If a session never existed, then it would not be possible to perform the requested action.  Therefore, an exception is appropriate. To help illustrate how to handle this situation, I've modified the following code in Program.cs in the LinqToTwitterDemo project to illustrate the situation: static void EndSession(ITwitterAuthorizer auth) { using (var twitterCtx = new TwitterContext(auth, "https://api.twitter.com/1/", "https://search.twitter.com/")) { try { //Log twitterCtx.Log = Console.Out; var status = twitterCtx.EndAccountSession(); Console.WriteLine("Request: {0}, Error: {1}" , status.Request , status.Error); } catch (TwitterQueryException tqe) { var webEx = tqe.InnerException as WebException; if (webEx != null) { var webResp = webEx.Response as HttpWebResponse; if (webResp != null && webResp.StatusCode == HttpStatusCode.Unauthorized) Console.WriteLine("Twitter didn't recognize you as having been logged in. Therefore, your request to end session is illogical.\n"); } var status = tqe.Response; Console.WriteLine("Request: {0}, Error: {1}" , status.Request , status.Error); } } } As expected, LINQ to Twitter wraps the exception in a TwitterQueryException as the InnerException.  The TwitterQueryException serves a very useful purpose through it's Response property.  Notice in the example above that the response has Request and Error proprieties.  These properties correspond to the information that Twitter returns as part of it's response payload.  This is often useful while debugging to help you understand why Twitter was unable to perform the  requested action.  Other times, it's cryptic, but that's another story.  At least you have some way of knowing in your code how to anticipate and handle these situations, along with having extra information to debug with. To sum things up, there are two points to make: when and why an exception should be raised and when to wrap and re-throw an exception in a custom exception type. I felt it was necessary to allow the exception to be raised because the called method was unable to perform the task it was designed for.  I also felt that it is inappropriate for a general library to do anything with exceptions because that could potentially hide a problem from the caller.  A related point is that it should be the exclusive decision of the application that uses the library on what to do with an exception.  Another aspect of this situation is that I wrapped the exception in a custom exception and re-threw.  This is a tough call because I don’t want to hide any stack trace information.  However, the need to make the exception more meaningful by including vital information returned from Twitter swayed me in the direction to design an interface that was as helpful as possible to library consumers.  As shown in the code above, you can dig into the exception and pull out a lot of good information, such as the fact that the underlying HTTP response was a 401 Unauthorized.  In all, trade-offs are seldom perfect for all cases, but combining the fact that the method was unable to perform its intended function, this is a library, and the extra information can be more helpful, it seemed to be the better design. @JoeMayo

• MVC App Works in Visual Studio, but not IIS7

  - by kesh

  Working on a an ASP.NET MVC Project, and I'm having some difficulties deploying to a shared dev server. Locally, when debugging using the local Visual Studio 2008 server, everything works peachy. However, once deployed, I receive the following error: Parser Error Description: An error occurred during the parsing of a resource required to service this request.

• Covering Earth with Hexagonal Map Tiles

  - by carrier

  Many strategy games use hexagonal tiles. One of the main advantages is that the distance between the center of any tile and all its neighboring tiles is the same. I was wondering if anyone has any thoughts on marrying a hexagonal tile system with the traditional geographic system (longitude/latitude). I think it would be interesting to cover a globe with hexagonal tiles and be able to map a geographic coordinate to a tile. Has anyone seen anything remotely close to this before? UPDATE I'm looking for a way to subdivide the surface of a sphere so that each division has the same surface area. Ideally, the centers of adjacent sub-divisions would be equidistant.

• ASP.NET: Custom MembershipProvider with a custom user table

  - by blahblah

  I've recently started tinkering with ASP.NET MVC, but this question should apply to classic ASP.NET as well. For what it's worth, I don't know very much about forms authentication and membership providers either. I'm trying to write my own MembershipProvider which will be connected to my own custom user table in my database. My user table contains all of the basic user information such as usernames, passwords, password salts, e-mail addresses and so on, but also information such as first name, last name and country of residence. As far as I understand, the standard way of doing this in ASP.NET is to create a user table without the extra information and then a "profile" table with the extra information. However, this doesn't sound very good to me, because whenever I need to access that extra information I would have to make one extra database query to get it. I read in the book "Pro ASP.NET 3.5 in C# 2008" that having a separate table for the profiles is not a very good idea if you need to access the profile table a lot and have many different pages in your website. Now for the problem at hand... As I said, I'm writing my own custom MembershipProvider subclass and it's going pretty well so far, but now I've come to realize that the CreateUser doesn't allow me to create users in the way I'd like. The method only takes a fixed number of arguments and first name, last name and country of residence are not part of them. So how would I create an entry for the new user in my custom table without this information at hand in CreateUser of my MembershipProvider?

• Dynamic Google Maps API InfoWindow HTML Content

  - by Peter Hanneman

  I am working in Flash Builder 4 with Google Map's ActionScript API. I have created a map, loaded some custom markers onto it and added some MouseEvent listeners to each marker. The trouble comes when I load an InfoWindow panel. I want to dynamically set the htmlContent based off of information stored in a database. The trouble is that this information can change every couple of seconds and each marker has a unique data set so I can not statically set it at the time I actually create the markers. I have a method that will every minute or so load all of the records from my database into an Object variable. Everything I need to display in the htmlContent is contained in this object under a unique identifier. The basic crux of the problem is that there is no way for me to uniquely identify an info window, so I can not determine what information to pull into the panel. marker.addEventListener(MapMouseEvent.ROLL_OVER, function(e:MapMouseEvent):void { showInfoWindow(e.latLng) }, false, 0, false); That is my mouse event listener. The function I call, "showInfowindow" looks like this: private function showInfoWindow(latlng:LatLng):void { var options:InfoWindowOptions = new InfoWindowOptions({title: appData[*I NEED A UNIQUE ID HERE!!!*].type + " Summary", contentHTML: appData[*I NEED A UNIQUE ID HERE!!!*].info}); this.map.openInfoWindow(latlng, options); } I thought I was onto something by being able to pass a variable in my event listener declaration, but it simply hates having a dynamic variable passed through, it only returns the last value use. Example: marker.addEventListener(MapMouseEvent.ROLL_OVER, function(e:MapMouseEvent):void { showInfoWindow(e.latLng, record.unit_id) }, false, 0, false); That solution is painfully close to working. I iterate through a loop to create my markers when I try the above solution and roll over a marker I get information, but every marker's information reflects whatever information the last marker created had. I apologize for the long explaination but I just wanted to make my question as clear as possible. Does anyone have any ideas about how to patch up my almost-there-solution that I posted at the bottom or any from the ground up solutions? Thanks in advance, Peter Hanneman

• Choosing the right web service

  - by Ratan Sharma

  My website currently working in ASP.NET 1.1 Old Process In our database we have huge amount of data stored for a decoding purpose. We have to update this huge set of data table each week(Data is supplied from a vendor). In our website (in asp.net 1.1) we query our database to decode information. New process Now instead of storing data in our database and query them, we want to replace this through the web service, AS now the vendor is supplying us a DLL, which will give us the decoded information. Information on the DLL provided by the vendor The DLL provided, can only be added in 4.0 sites. SO that also impleies that i can not directly add the dll to my 1.1 site. This DLL is exposing certain methods, we simply have to add the DLL refernce in our web service and call the method and fetch the needed information. Thus we will not have to store those information in our database. So which type of web service I should go for (asmx OR WCF) that will use the DLLs provided by vendor to fetch the decoded information ?? Flexibility i am looking for in the web service are: It can be consumed from asp.net 1.1 site directly and also using jQuery ajax. It can be consumed from other web services running on the server. It can be consumed from some windows services running from the server. NOTE : Moreover we have a plan to migrate our website from asp.net 1.1 to 4.0 version in future.So it should be that much supportive for future upgrade.

• URL naming conventions

  - by LookitsPuck

  So, this may be a can of worms. But I'm curious what your practices are? For example, let's say your website consists of the following needs (very basic): A landing page An information page for an event (static) A listing of places for that event (dynamic) An information page for each place With that said, how would you design your URLs? Typically, I'd do something like the following: www.domain.com/ - landing page [also accessible via www.domain.com/home] www.domain.com/event - event information page www.domain.com/places - listing of all places www.domain.com/places/{id} - place information page Now, here's a question. Just grammatically speaking, I have a hangup of referring to a given place in a url as being plural. Shouldn't it make more sense to go with this: www.domain.com/place/{id} as opposed to www.domain.com/places/{id} In some frameworks, you have a convention to follow (for example, ASP.NET MVC) by default. Yes, you can define custom routes to have /place/{id} route to the PlacesController. However, I'm just trying to keep this a bit abstract in discussion. With that being said, let's see for instance on another page of your site, you have a link, that when clicked, would open a modal popup populated with place information. Where you place that information? We could go with something like this: www.domain.com/ajax/places/{id} OR www.domain.com/places/{id} and serve based on the request header (that is, if requesting JSON, return JSON?}. Finally, for SEO reasons, typically I use a slug associated with a given resource. So, something like such: www.domain.com/ajax/places/{id}/london Where london is only there to add decoration to the link for SEO reasons. Is this sound? I ask all of these questions, because these are practices that I've been using for awhile, and I'd just like to see what other developers are doing or if I'm approaching things incorrectly. Thanks!

• Passing session between jsf backing bean and model

  - by Rachel

  Background : I am having backing bean which has upload method that listen when file is uploaded. Now I pass this file to parser and in parser am doing validation check for row present in csv file. If validation fails, I have to log information and saving in logging table in database. My end goal : Is to get session information in logging bean so that I can get initialContext and make call to ejb to save data to database. What is happening : In my upload backing bean, am getting session but when i call parser, I do not pass session information as I do not want parser to be dependent on session as I want to unit test parser individually. So in my parser, I do not have session information, from parser am making call to logging bean(just a bean with some ejb methods) but in this logging bean, i need session because i need to get initial context. Question Is there a way in JSF, that I can get the session in my logging bean that I have in my upload backing bean? I tried doing: FacesContext ctx = FacesContext.getCurrentInstance(); HttpSession session = (HttpSession) ctx.getExternalContext().getSession(false); but session value was null, more generic question would be : How can I get session information in model bean or other beans that are referenced from backing beans in which we have session? Do we have generic method in jsf using which we can access session information throughout JSF Application?

• How to debug JBoss out of memory problem?

  - by user561733

  Hello, I am trying to debug a JBoss out of memory problem. When JBoss starts up and runs for a while, it seems to use memory as intended by the startup configuration. However, it seems that when some unknown user action is taken (or the log file grows to a certain size) using the sole web application JBoss is serving up, memory increases dramatically and JBoss freezes. When JBoss freezes, it is difficult to kill the process or do anything because of low memory. When the process is finally killed via a -9 argument and the server is restarted, the log file is very small and only contains outputs from the startup of the newly started process and not any information on why the memory increased so much. This is why it is so hard to debug: server.log does not have information from the killed process. The log is set to grow to 2 GB and the log file for the new process is only about 300 Kb though it grows properly during normal memory circumstances.

• Lookback API: How long is a defect in a particular state?

  - by user1195996

  We have a state in our defects called "Need More Information". I would like to create a graph over time of how many defects are in that state at any particular period of time. I think I can get the info to do that with the Lookback API with the following query: my $find = { State => 'Need More Information', '_PreviousValues.State' => {'$ne' => 'Need More Information'}, _TypeHierarchy => -51006, # defect _ValidFrom => { '$gte' => '2012-09-01TZ', '$lt' => '2012-10-23TZ', } I thought that would give me back a list of all defect snapshots where the defect was transitioning into "Need More Information" state, but it does not (seems to list everything that was ever in "Need More Information" state. Technically what I need is a query that lists snapshots of any defects transitioning either TO OR FROM the "Need More Information" state, but since this simpler one did not seem to work as I expected, I thought I would ask first why the query above did not work the way I expected.

• How important is it that models be consistent across project components?

  - by RonLugge

  I have a project with two components, a server-side component and a client-side component. For various reasons, the client-side device doesn't carry a fully copy of the database around. How important is it that my models have a 1:1 correlation between the two sides? And, to extend the question to my bigger concern, are there any time-bombs I'm going to run into down the line if they don't? I'm not talking about having different information on each side, but rather the way the information is encapsulated will vary. (Obviously, storage mechanisms will also vary) The server side will store each user, each review, each 'item' with seperate tables, and create links between them to gather data as necessary. The client side shouldn't have a complete user database, however, so rather than link against the user for gathering things like 'name', I'd store that on the review. In other words... --- Server Side --- Item: +id //Store stuff about the item User: +id +Name -Password Review: +id +itemId +rating +text +userId --- Device Side --- Item: +id +AverageRating Review: +id +rating +text +userId +name User: +id +Name //Stuff The basic idea is that certain 'critical' information gets moved one level 'up'. A user gets the list of 'items' relevant to their query, with certain review-orientation moved up (i. e. average rating). If they want more info, they query the detail view for the item, and the actual reviews get queried and added to the dataset (and displayed). If they query the actual review, the review gets queried and they pick up some additional user info along the way (maybe; I'm not sure if the user would have any use for any of the additional user information). My basic concern is that I don't wan't to glut the user's bandwidth or local storage with a huge variety of information that they just don't need, even if proper database normalizations suggests that information REALLY should be stored at a 'lower' level. I've phrased this as a fairly low-level conceptual issue because that's the level I'm trying to think / worry over, but if it matters I'm creating a PHP / MySQL server that provides data for a iOS / CoreData client.

• Best way to store this data?

  - by Malfist

  I have just been assigned to renovate an old website, and I get to move it from some old archaic system to drupal. The only problem is that it's a real-estate system and a lot of data is stored. Currently all the information is stored in a single table, an id represents the house and then everything else is key/value pairs. There are a possible 243 keys per estate, there are 23840 estates in the system. As you can imagine the system is slow and difficult to query. I don't think a table with 243 rows would be a very good idea, and probably worse than the current situation. I've done some investigating and here's what I've found out: Missing data does not indicate a 0 value, data is merged from two, unique sources/formats. Some guessing is involved. I have no control over the source of the data. There are 4 keys that are common to all estates, all values look like something that is commonly searched for and could be indexed There are 10 keys that are in the [90-100)% range 8 of these are information like who's selling it, and it's address. The other two seem to belong with the below range There are 80 keys that are in the [80-90)% range This range seems to mostly just list room types and how many the house has (e.g. bedrooms_possible, bathrooms, family_room_3rd, etc) This range also includes some minor information like school districts, one or two more pieces of data on the address. The 179 keys that are in the [0-80)% range include all sorts of miscellaneous information about the estate My best idea was a hybrid approach, create a table that stores important, common information and keep a smaller key/value table. How would you store this information?

• Using DEBUG Mode in Oracle SQL Developer to Log SQL

  - by thatjeffsmith

  Curious how we’re getting the data you see in SQL Developer when you click on something? While many of the dialogs provide a ‘SQL’ panel that shows you the SQL ABOUT to be generated, I’d rather see the SQL AS it’s executed. True, you could set a TRACE or fire up a Monitor Sessions report, but both of those solutions leave me hungry for more. Did you know that SQL Developer has a ‘debug’ mode? It slows the tool down a bit and spits out a lot of information you don’t care about, but it ALSO shows you ALL the SQL that is sent to the database, as you click around the tool! See ALL the SQL that SQL Developer sends to the database on your behalf Enable DEBUG Mode When you see the splash screen as SQL Developer fires up, frantically hit Up, Up, Down, Down, Left, Right, Left, Right, B, A, SELECT, Start. Wait, wrong game. No, all you need to do is go to your SQL Developer directory and navigate down to the ‘bin’ directory. In that directory, find the ‘sqldeveloper.conf’ file. Install Directory - sqldeveloper - bin - sqldeveloper.conf Open it with a text editor. Find this line IncludeConfFile sqldeveloper-nondebug.conf And replace it with this line IncludeConfFile sqldeveloper-debug.conf Save the file. Start up SQL Developer. Observe the Logging Page – Log Panel for the SQL There’s going to be more than just SQL here. You’ll actually see a LOT of other information. If you’re having general problems with the tool and you want to see the nitty-gritty of what’s going on, then this is a good place to satisfy your curiosity and might help us diagnose your issue if you post to the forums or open a ticket with My Oracle Support. You’ll find ‘INFO’ entries that look a little something like this - This is the query used to populate your Tables list in the connection tree. You can double-click on the sql text and get a pop-up window that’s much easier to read. See all that typing we’re saving you? I don’t recommend running in DEBUG mode all the time. Capturing this information and displaying it is more expensive than not doing so. And it provides a lot of information you don’t normally need to see. But when you DO want to know what’s going on and why, this is an excellent way of getting that information. When you’re ready to go back to ‘normal’ mode, just close SQL Developer, go back to your .conf file, and add the ‘nondebug’ bit back.

• Data Masking Pack 12.1.0.3 Certified with E-Business Suite 12.1.3

  - by Elke Phelps (Oracle Development)

  I'm pleased to announce the certification of the E-Business Suite 12.1.3 Data Masking Template for the Data Masking Pack with Enterprise Manager Cloud Control 12.1.0.3. You can use the Oracle Data Masking Pack with Oracle Enterprise Manager Grid Control 12c to scramble sensitive data in cloned E-Business Suite environments.     You may scramble data in E-Business Suite cloned environments with EM12.1.0.3 using the following template: E-Business Suite 12.1.3 Data Masking Template for Data Masking Pack with EM12c (Patch 18462641) What does data masking do in E-Business Suite environments? Application data masking does the following: De-identify the data:  Scramble identifiers of individuals, also known as personally identifiable information or PII.  Examples include information such as name, account, address, location, and driver's license number. Mask sensitive data:  Mask data that, if associated with personally identifiable information (PII), would cause privacy concerns.  Examples include compensation, health and employment information.   Maintain data validity:  Provide a fully functional application.  How can EBS customers use data masking? The Oracle E-Business Suite Template for Data Masking Pack can be used in situations where confidential or regulated data needs to be shared with other non-production users who need access to some of the original data, but not necessarily every table.  Examples of non-production users include internal application developers or external business partners such as offshore testing companies, suppliers or customers.  Due to data dependencies, scrambling E-Business Suite data is not a trivial task.  The data needs to be scrubbed in such a way that allows the application to continue to function. The template works with the Oracle Data Masking Pack and Oracle Enterprise Manager to obscure sensitive E-Business Suite information that is copied from production to non-production environments.  The Oracle E-Business Suite Template for Data Masking Pack is applied to a non-production environment with the Enterprise Manager Grid Control Data Masking Pack.  When applied, the Oracle E-Business Suite Template for Data Masking Pack will create an irreversibly scrambled version of your production database for development and testing. Is there a charge for this? Yes. You must purchase licenses for the Oracle Data Masking Pack to use the Oracle E-Business Suite 12.1.3 template. The Oracle E-Business Suite 12.1.3 Template for the Data Masking Pack is included with the Oracle Data Masking Pack license.  You can contact your Oracle account manager for more details about licensing.

• AutoVue at the Oracle Asset Lifecycle Management Summit

  - by celine.beck

  I recently had the opportunity to attend and present the integration between AutoVue and Primavera P6 during the Oracle ALM Summit, which was held in March at Redwood Shores, on Oracle Headquarters grounds. The ALM Summit brought together over 300 Oracle maintenance practitioners who endured the foggy and rainy San Francisco weather to attend the 4th edition of this Oracle-driven conference. Attendees have roles in maintenance management and IT. Following a general session, Ralph Rio from ARC Advisory Group provided a very interesting keynote session discussing Asset Management directions, both in the short and long run. An interesting point that Ralph raised is that most organizations have done a good job at improving performance at the design / build, operate and maintain and portfolio management phases by leveraging solutions like Asset Lifecycle Management and Project & Portfolio management solutions; however, there seem to be room for improvement in between those phases, when information flows from one group to the other, during the data handover phase or when time comes to update / modify drawings to reflect the reality of physical assets. This is where AutoVue comes into play. By integrating with enterprise applications like content management systems, asset lifecycle management applications and project management solutions, AutoVue can be a real-process enabler, streamlining information flows from concept/design to decommissioning and ensuring that all project stakeholders have access to asset information and engineering data throughout the asset lifecycle. AutoVue's built-in digital annotation capabilities allows maintenance workers and technicians to report changes in configuration and visually capture the delta between as-built and as-maintained versions of asset documents. This information can then be easily handed over to engineers who can identify changes and incorporate these modifications into the drawings during the next round of document revisions. PPL Power Generation, an electric utilities headquarted in Allentown, Pennsylvania discussed this usage of AutoVue during an interesting Webcast around AutoVue's role in the Utilities space. After the keynote sessions, participants broke off into product-centric tracks around Oracle's Asset Lifecycle Management solutions (E-Business Suite, PeopleSoft, and JD Edwards). The second day of the conference was the occasion for us to present the integration between AutoVue and Primavera P6 to the Maintenance Summit audience. The presentation was a great success and generated much discussion with partners and customers during breaks. People seemed highly interested in learning more about our plans for integrating AutoVue and Primavera P6 with Oracle's ALM solutions...stay tune for further information on the subject!

• The Minimalist Approach to Content Governance - Retire Phase

  - by Kellsey Ruppel

   Originally posted by John Brunswick. Good news - the Retire Phase is actually more fun than the Manage Phase. During the Retire Phase our content management team should not have to track down content creators if the Request Phase of this process was completed successfully. The ownership meta data, success criteria and time stamp that was applied to the original content submission will help to manage content at the end of the content life cycle. The Retire Phase will provide the opportunity for us to prune irrelevant content items through archiving or deletion, keeping the content system clear of irrelevant information, streamlining users ability to browse and search for content.   1. Act on Metrics Established during the Request Phase Why - Some information is only relevant for a given amount of time. In Content Platform Migration Strategy - Artifacts vs Perishable Content we examined two content types - Artifacts and Perishable content. Understanding the differences between Artifacts and Perishable content will allow us to explicitly respect their various lifespans. Additionally, some content may have been part of a project that failed to meet the success criteria outlined in the Request Phase. Any content that did not meet the metrics outlined in the Request Phase should be considered for deletion. How - Thankfully by adhering to to The Minimalist Approach to Content Governance our content should have some level of meta data associated with it that will allow us to quickly sort and understand how to deal with it. Content Management Systems like Oracle's Universal Content Management (UCM) natively allow you to create and save advanced searches that can use content meta data like folders, author, expiration date, security settings and custom meta data to pull back listings of content for examination. Additionally, analytics are available for all content items that allow us to determine if the usage is meeting success criteria that may have been previously outlined during the request phase. The lists that are produced from these approaches can be quickly reviewed for each project with the content owners and based on the nature of the content and success criteria undergo archiving or deletion. Impact - Retiring content that is no longer relevant will allow end users to have fast and relevant access to information across your enterprise. As we mentioned in our first post in this series - it is easy to quickly start producing content, but the challenge is ensuring that the environment is easy to navigate and use on the third week and during the third year. The light level of effort that was placed into the Request Phase of this process will set us up to keep content clean and relevant for a long time to come. With an up-to-date content repository users will be able to quickly find access to the information that is critical to their work processes. You might not get a holiday named in your honor managing the content system, but will appreciate their quick access to quality information.

• Introducing the Oracle MDM Blog - Why All MDM Solutions Aren't Equal

  - by ken.pulverman

  Welcome to the Oracle MDM Blog.  Dave Butler, Tony Ouk, and myself - Ken Pulverman, will be bringing you news and information from the world of MDM at Oracle.  Dave is our resident expert with more than 30 years of experience in data and information management. Tony has deep expertise in our Exadata product line which provides a strong hardware synergy with MDM.  I come from Siebel Systems where I helped found the team that built our integration product line and then our Universal Customer Master with is part of our MDM offering at Oracle. I thought I'd hit the ground running with a topic we are going to want to continue to bend your ear about.  We had a recent meeting with Ford Goodman, our head of MDM commercial sales in the US and he was very fired up about and important topic.  He's irked that all MDM solutions get painted with the same brush even though they aren't the same at all. There are companies out there trying to represent frameworks and toolkits as out of the box solutions.  They give you the pleasure (read pain) of doing things like developing your own multi-application data model, building your own web services, or creating your own APIs.  Huh?  What gets sold as flexibility in reality is a barrier to ever going live.  At Siebel Systems we obsessed over the notion of a customer.  Our data model took over 10 years to perfect as defining a customer is a very complex task indeed.  There are divisions, subsidiaries, branches, acquisitions, sites etc., etc., etc..  You'll want to do your homework, but trust me - you aren't going to want to take the time or resource to build these canonical data structures yourself.  And what about APIs?  Again, it sounds flexible.  In reality it's a lot of work. Our DNA at Oracle is to reduce the cost of information technology so we pre-integrate our technology with all of our major applications and pre-build integrations and connectors for all the major systems you work with.  This is tedious work that requires detailed knowledge of the interfaces of all the applications involved.  It is also version specific as the interface features and technology are always changing.  We have a substantial organization to manage this complexity so you don't have to.  Suffice to say, we'd like to help our customers peel back the rhetoric of companies that fly the MDM flag without a real offering that you can quickly benefit from. Please watch this space for more information on this storyline as well as news and information around Oracle MDM.

• July, the 31 Days of SQL Server DMO’s – Day 24 (sys.dm_db_index_operational_stats)

  - by Tamarick Hill

  The sys.dm_db_index_operational_stats Dynamic Management Function returns information about the IO, locking, and access methods for the indexes that you currently have on your SQL Server Instance. This function takes four input parameters which are (1) database_id, (2) object_id, (3) index_id, and (4) partition_number. Let’s have a look at the results from this function against our AdventureWorks2012 database. This function returns a ton of columns, so not only will I not attempt to describe each of the columns, I wont even attempt to display all of them here. My query below will give you a subset of the columns returned from this function. SELECT database_id, object_id, index_id, partition_number, leaf_insert_count, leaf_delete_count, leaf_update_count, leaf_ghost_count, nonleaf_insert_count, nonleaf_delete_count, nonleaf_update_count, range_scan_count, forwarded_fetch_count, row_lock_count, row_lock_wait_count, page_lock_count, page_lock_wait_count, Index_lock_promotion_attempt_count, index_lock_promotion_count, page_compression_attempt_count, page_compression_success_count FROM sys.dm_db_index_operational_stats(db_id('AdventureWorks2012'), NULL, NULL, NULL) The first four columns in the result set represent the values that we passed in as our input parameters. If you use NULL’s as I did, then you will see results for every index on your system. I specified a database_id so my result set only shows those records pertaining to my AdventureWorks2012 database. The next columns in the result set provide you with information on how may inserts, deletes, or updates that have taken place on your leaf and nonleaf index levels. The nonleaf levels would refer to the intermediate and root index levels. In the middle of these you see a leaf_ghost_count column, which represents the number of records that have been logically deleted and marked as “ghosted”  and are waiting on the background ghost cleanup process to physically remove them. The range_scan_count column represents the number of range or table scans that have been performed against an index. The forwarded_fetch_count column represents the number of rows that were returned from a forwarding row pointer. The row_lock_count and row_lock_wait_count represent the number of row locks that have been requested for an index and the number of times SQL has had to wait on a row lock respectively. The page_lock_count and page_lock_wait_count represent the number of page locks that have been requested for an index and the number of times SQL has had to wait on a page lock respectively. The index_lock_promotion_attempt_count represents the number of times the database engine has attempted to promote a lock to the index level. The index_lock_promotion_count column displays how many times that index lock promotion was successful. Lastly the page_compression_attempt_count and page_compression_success_count represents how many times a page was attempted to be compressed and how many times the attempt was successful. As you can see there is a ton of information returned from this DMV. The DMV we reviewed on yesterday (sys.dm_db_index_usage_stats) provided you with good information on when and how indexes have been used, but this DMF takes an even deeper dive into these statistics. If you are interested in performing a very detailed analysis on the operational stats of your indexes, this is not only a good place to start, but more than likely the best place. For more information on this Dynamic Management Function, please see the below Books Online link: http://msdn.microsoft.com/en-us/library/ms174281.aspx Follow me on Twitter @PrimeTimeDBA
