  • What is the differnce between an Oracle and Microsoft schema?

    - by Tarzan
    I am working on an enterprise project. Some of the team has an Oracle background and some has a Microsoft SQL Server background. There is much confusion when we talk about schemas. I am trying to provide some clarity. Is this an accurate way to describe the difference in the meaning of schemas between the two technologies? An Oracle schema is associated with a single user and consists of the objects owned by the user. A MS SQL Server schema schema is a namespace.

  • How to access Oracle system tables from inside of a PL/SQL function or procedure?

    - by mjumbewu
    I am trying to access information from an Oracle meta-data table from within a function. For example (purposefully simplified): CREATE OR REPLACE PROCEDURE MyProcedure IS users_datafile_path VARCHAR2(100); BEGIN SELECT file_name INTO users_datafile_path FROM dba_data_files WHERE tablespace_name='USERS' AND rownum=1; END MyProcedure; / When I try to execute this command in an sqlplus process, I get the following errors: LINE/COL ERROR -------- ----------------------------------------------------------------- 5/5 PL/SQL: SQL Statement ignored 6/12 PL/SQL: ORA-00942: table or view does not exist I know the user has access to the table, because when I execute the following command from the same sqlplus process, it displays the expected information: SELECT file_name FROM dba_data_files WHERE tablespace_name='USERS' AND rownum=1; Which results in: FILE_NAME -------------------------------------------------------------------------------- /usr/lib/oracle/xe/oradata/XE/users.dbf Is there something I need to do differently?

  • How to log the raw SQL from Oracle occi C++ api?

    - by savanna
    One of our customers is complaining our application is not working. Their reasoning is that our sql function call to their Oracle database is not getting the "expected" result. Sometime, it should failed but our application get success from their database. It's really frustrating because it's their database and we cannot do any test on it. We are using the C++ Oracle OCCI API. Is there anyway we can log the raw sql from our end? That will be very helpful and we can ship the script to them and let them debug in their system to figure out the problem. Thanks in advance.

  • BI and EPM Landscape

    - by frank.buytendijk
    Most of my blog entries are not about Oracle products, and most of the latest entries are about topics such as IT strategy and enterprise architecture. However, given my background at Gartner, and at Hyperion, I still keep a close eye on what's happening in BI and EPM. One important reason is that I believe there is significant competitive value for organizations getting BI and EPM right. Davenport and Harris wrote a great book called "Competing on Analytics", in which they explain this in a very engaging and convincing way. At Oracle we have defined the concept of "management excellence" that outlines what organizations have to do to keep or create a competitive edge. It's not only in the business processes, but also in the management processes. Recently, Gartner published its 2009 market shares report for BI, Analytics, and Performance Management. Gartner identifies the same three segments that Oracle does: (1) CPM Suites (Oracle refers not to Corporate Performance Management, but Enterprise Performance Management), (2) BI Platform, and (3) Analytic Applications & Performance Management. According to Gartner, Oracle's share is increasing with revenue growing by more than 5%. Oracle currently holds the #2 market share position in the overall BI Software space based on total BI software revenue. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 Gartner has ranked Oracle as #1 in the CPM Suites worldwide sub-segment based on total BI software revenue, and Oracle is gaining share with revenue growing by more than 6% in 2009. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 The Analytic Applications & Performance Management subsegment is more fragmented. It has for instance a very large "Other Vendors" category. The largest player traditionally is SAS. Analytic Applications are often meant for very specific analytic needs in very specific industry sectors. According to Gartner, from the large vendors, again Oracle is the one who is gaining the most share - with total BI software revenue growth close to 15% in 2009. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 I believe this shows Oracle's integration strategy is working. In fact, integration actually is the innovation. BI and EPM have been silo technology platforms and application suites way too long. Management and measuring performance should be very closely linked to strategy execution, which is the domain of other business application areas such as CRM, ERP, and Supply Chain. BI and EPM are not about "making better decisions" anymore, but are part of a tangible action framework. Furthermore, organizations are getting more serious about ecosystem thinking. They do not evaluate single tools anymore for different application areas, but buy into a complete ecosystem of hardware, software and services. The best ecosystem is the one that offers the most options, in environments where the uncertainty is high and investments are hard to reverse. The key to successfully managing such an environment is middleware, and BI and EPM become increasingly middleware intensive. In fact, given the horizontal nature of BI and EPM, sitting on top of all business functions and applications, you could call them "upperware". Many are active in the BI and EPM space. Big players can offer a lot, but there are always many areas that are covered by specialty vendors. Oracle openly embraces those technologies within the ecosystem as well. Complete, open and integrated still accurately describes the Oracle product strategy. frank

Click here for a two-page printable conference overview (PDF). Big Data with CEP and SOA - September 25, 2012 - 14:15 Speaker: Markus Zirn, Oracle and Baz Kuthi, Avocent The "Big Data" trend is driving new kinds of IT projects that process machine-generated data. Such projects store and mine using Hadoop/ Map Reduce, but they also analyze streaming data via event-driven patterns, which can be called "Fast Data" complementary to "Big Data". This session highlights how "Big Data" and "Fast Data" design patterns can be combined with SOA design principles into modern, event-driven architectures. We will describe specific architectures that combines CEP, Distributed Caching, Event-driven Network, SOA Composites, Application Development Framework, as well as Hadoop. Architecture patterns include pre-processing and filtering event streams as close as possible to the event source, in memory master data for event pattern matching, event-driven user interfaces as well as distributed event processing. Focus is on how "Fast Data" requirements are elegantly integrated into a traditional SOA architecture. Markus Zirn is Vice President of Product Management covering Oracle SOA Suite, SOA Governance, Application Integration Architecture, BPM, BPM Solutions, Complex Event Processing and UPK, an end user learning solution. He is the author of “The BPEL Cookbook” (rated best book on Services Oriented Architecture in 2007) as well as “Fusion Middleware Patterns”. Previously, he was a management consultant with Booz Allen & Hamilton’s High Tech practice in Duesseldorf as well as San Francisco and Vice President of Product Marketing at QUIQ.

  • ArchBeat Link-o-Rama Top 10 for September 9-15, 2012

    - by Bob Rhubart
    The Top 10 most-viewed items shared on the OTN ArchBeat Facebook page for the week of September 9-15, 2017. 15 Lessons from 15 Years as a Software Architect | Ingo Rammer In this presentation from the GOTO Conference in Copenhagen, Ingo Rammer shares 15 tips regarding people, complexity and technology that he learned doing software architecture for 15 years. Attend OTN Architect Day – by Architects, for Architects – October 25 You won't need 3D glasses to take in these live presentations (8 sessions, two tracks) on Cloud computing, SOA, and engineered systems. And the ticket price is: Zero. Nothing. Absolutely free. Register now for Oracle Technology Network Architect Day in Los Angeles. Thursday October 25, 2012, 8:00 a.m. – 5:00 p.m. Sofitel Los Angeles , 8555 Beverly Boulevard , Los Angeles, CA 90048. Cloud API and service designers, stop thinking small | Cloud Computing - InfoWorld "The focus must shift away from fine-grained APIs that provide some type of primitive service, such as pushing data to a block of storage or perhaps making a request to a cloud-rooted database," says InfoWorld's David Linthicum. "To go beyond primitives, you must understand how these services should be used in a much larger architectural context. In other words, you need to understand how businesses will employ these services to form real workplace solutions—inside and outside the enterprise." Adding a runtime picker to a taskflow parameter in WebCenter | Yannick Ongena Oracle ACE Yannick Ongena shows how to create an Oracle WebCenter popup to allow users to "select items or do more complex things." Oracle IAM 11g R2 docs are now available "One of the great things about the new doc set is the inclusion of ePub files," says Fusion Middleware A-Team blogger Chris Johnson. "This means that if you have an iPad you can load up the doc library onto that and read the docs on the couch." Setting up a local Yum Server using the Exalogic ZFS Storage Appliance | Donald A concise technical post from the man named Donald. What's New in Oracle VM VirtualBox 4.2? | The Fat Bloke Sings "One of the trends we've seen is that as the average host platform becomes more powerful, our users are consistently running more and more vm's," says The Fat Bloke. "Some of our users have large libraries of vm's of various vintages, whilst others have groups of vm's that are run together as an assembly of the various tiers in a multi-tiered software solution, for example, a database tier, middleware tier, and front-ends." The new VirtualBox release, a year in the making, addresses the needs of these users, he explains. Configuring Oracle Business Intelligence 11g MDS XML Source Control Management with Git Version Control | Christian Screen Oracle ACE Christian Screen developed this tutorial for those interested in learning how to configure the Oracle Business Intelligence 11g (11.1.1.6) metadata repository for development using the new MDS XML source control management functionality. Identity and Access Management at Oracle Open World 2012 | Brian Eidelman Fusion Middleware A-Team blogger Brian Eideleman highlights three Oracle Openworld sessions that will put Identity and Access Management in the spotlight, and shares a link to the "Focus On: Identity Management" document, a comprehensive listing of Openworld activities also dealing with IM. Starting and stopping WebLogic automatically using Upstart | Chris Johnson "In Ubuntu, RedHat and Oracle Linux there's a new flavor of init called Upstart that all the kids are using," says Oracle Fusion Middleware A-Team member Chris Johnson. "It's the new hotness when it comes to making programs into daemons and wiring them to start and stop at appropriate times." Thought for the Day "The purpose of software engineering is to control complexity, not to create it." — Pamela Zave Source: SoftwareQuotes.com

  • ArchBeat Link-o-Rama Top 10 for December 9-15, 2012

    - by Bob Rhubart
    You click, we listen. The following list reflects the Top 10 most popular items posted on the OTN ArchBeat Facefbook page for the week of December 9-15, 2012. DevOps Basics II: What is Listening on Open Ports and Files – WebLogic Essentials | Dr. Frank Munz "Can you easily find out which WebLogic servers are listening to which port numbers and addresses?" asks Dr. Frank Munz. The good doctor has an answer—and a tech tip. Using OBIEE against Transactional Schemas Part 4: Complex Dimensions | Stewart Bryson "Another important entity for reporting in the Customer Tracking application is the Contact entity," says Stewart Bryson. "At first glance, it might seem that we should simply build another dimension called Dim – Contact, and use analyses to combine our Customer and Contact dimensions along with our Activity fact table to analyze Customer and Contact behavior." SOA 11g Technology Adapters – ECID Propagation | Greg Mally "Many SOA Suite 11g deployments include the use of the technology adapters for various activities including integration with FTP, database, and files to name a few," says Oracle Fusion Middleware A-Team member Greg Mally. "Although the integrations with these adapters are easy and feature rich, there can be some challenges from the operations perspective." Greg's post focuses on technical tips for dealing with one of these challenges. Podcast: DevOps and Continuous Integration In Part 1 of a 3-part program, panelists Tim Hall (Senior Director of product management for Oracle Enterprise Repository and Oracle’s Application Integration Architecture), Robert Wunderlich (Principal Product Manager for Oracle’s Application Integration Architecture Foundation Pack) and Peter Belknap (Director of product management for Oracle SOA Integration) discuss why DevOps matters and how it changes development methodologies and organizational structure. Good To Know - Conflicting View Objects and Shared Entity | Andrejus Baranovskis Oracle ACE Director Andrejus Baranovskis shares his thoughts -- and a sample application -- dealing with an "interesting ADF behavior" encountered over the weekend. Cloud Deployment Models | B. R. Clouse Looking out for the cloud newbies... "As the cloud paradigm grows in depth and breadth, more readers are approaching the topic for the first time, or from a new perspective," says B. R. Clouse. "This blog is a basic review of cloud deployment models, to help orient newcomers and neophytes." Service governance morphs into cloud API management | David Linthicum "When building and using clouds, the ability to manage APIs or services is the single most important item you can provide to ensure the success of the project," says David Linthicum. "But most organizations driving a cloud project for the first time have no experience handling a service-based architecture and don't see the need for API management until after deployment. By then, it's too late." Oracle Fusion Middleware Security: Password Policy in OAM 11g R2 | Rob Otto Rob Otto continues the Oracle Fusion Middleware A-Team "Oracle Access Manager Academy" series with a detailed look at OAM's ability to support "a subset of password management processes without the need to use Oracle Identity Manager and LDAP Sync." Understanding the JSF Lifecycle and ADF Optimized Lifecycle | Steven Davelaar Could you call that a surprise ending? Oracle WebCenter & ADF Architecture Team (A-Team) member learned a lot more than he expected while creating a UKOUG presentation entitled "What you need to know about JSF to be succesful with ADF." Expanding on requestaudit - Tracing who is doing what...and for how long | Kyle Hatlestad "One of the most helpful tracing sections in WebCenter Content (and one that is on by default) is the requestaudit tracing," says Oracle Fusion Middleware A-Team architect Kyle Hatlestad. Get up close and technical in his post. Thought for the Day "There is no code so big, twisted, or complex that maintenance can't make it worse." — Gerald Weinberg Source: SoftwareQuotes.com

  • Two Weeks To Go, Still Time to Register

    - by speakjava
    Yes, it's now only two weeks to the start of the 17th JavaOne conference! This will be my ninth JavaOne, I came fairly late to this event, attending for the first time in 2002.  Since then I've missed two conferences, 2006 for the birth of my son (a reasonable excuse I think) and 2010 for reasons we'll not go into here.  I have quite the collection of show devices, I've still got the WoWee robot, the HTC phone for JavaFX, the programmable pen and the Sharp Zaurus.  The only one I didn't keep was the homePod music player (I wonder why?) JavaOne is a special conference for many reasons, some of which I list here: A great opportunity to catch up on the latest changes in the Java world.  This is not just in terms of the platform, but as much about what people are doing with Java to build new and cool applications. A chance to meet people.  We have these things called BoFs, which stands for "Birds of a Feather", as in "Birds of a feather, flock together".  The idea being to have sessions where people who are interested in the same topic don't just get to listen to a presentation, but get to talk about it.  These sessions are great, but I find that JavaOne is as much about the people I meet in the corridors and the discussions I have there as it is about the sessions I get to attend. Think outside the box.  There are a lot of sessions at JavaOne covering the full gamut of Java technologies and applications.  Clearly going to sessions that relate to your area of interest is great, but attending some of the more esoteric sessions can often spark thoughts and stimulate the imagination to go off and do new and exciting things once you get back. Get the lowdown from the Java community.  Java is as much about community as anything else and there are plenty of events where you can get involved.  The GlassFish party is always popular and for Java Champions and JUG leaders there's a couple of special events too. Not just all hard work.  Oracle knows how to throw a party and the appreciation event will be a great opportunity to mingle with peers in a more relaxed environment.  This year Pearl Jam and Kings of Leon will be playing live.  Add free beer and what more could you want? So there you have it.  Just a few reasons for why you want to attend JavaOne this year.  Oh, and of course I'll be presenting three sessions which is even more reason to go.  As usual I've gone for some mainstream ("Custom Charts" for JavaFX) and some more 'out there' ("Java and the Raspberry Pi" and "Gestural Interfaces for JavaFX").  Once again I'll be providing plenty of demos so more than half my luggage this year will consist of a Kinect, robot arm, Raspberry Pis, gamepad and even an EEG sensor. If you're a student there's one even more attractive reason for going to JavaOne: It's Free! Registration is here.  Hope to see you there!

SQL PLAN DIRECTIVES, SQL PLAN DIRECTIVES???retention ???53?: Package: DBMS_SPD This package provides subprograms for managing Sql Plan Directives(SPD). SPD are objects generated automatically by Oracle server. For example, if server detects that the single table cardinality estimated by optimizer is off from the actual number of rows returned when accessing the table, it will automatically create a directive to do dynamic sampling for the table. When any Sql statement referencing the table is compiled, optimizer will perform dynamic sampling for the table to get more accurate estimate. Notes: DBMSL_SPD is a invoker-rights package. The invoker requires ADMINISTER SQL MANAGEMENT OBJECT privilege for executing most of the subprograms of this package. Also the subprograms commit the current transaction (if any), perform the operation and commit it again. DBA view dba_sql_plan_directives shows all the directives created in the system and the view dba_sql_plan_dir_objects displays the objects that are included in the directives. -- Default value for SPD_RETENTION_WEEKS SPD_RETENTION_WEEKS_DEFAULT CONSTANT varchar2(4) := '53'; | STATE : NEW : Newly created directive. | : MISSING_STATS : The directive objects do not | have relevant stats. | : HAS_STATS : The objects have stats. | : PERMANENT : A permanent directive. Server | evaluated effectiveness and these | directives are useful. | | AUTO_DROP : YES : Directive will be dropped | automatically if not | used for SPD_RETENTION_WEEKS. | This is the default behavior. | NO : Directive will not be dropped | automatically. Procedure: flush_sql_plan_directive This procedure allows manually flushing the Sql Plan directives that are automatically recorded in SGA memory while executing sql statements. The information recorded in SGA are periodically flushed by oracle background processes. This procedure just provides a way to flush the information manually. ????”_optimizer_dynamic_plans”(enable dynamic plans)????????,???TRUE??DYNAMIC PLAN? ???FALSE???????????? ????,Dynamic Plan????????????Nested Loop?Hash Join???case ,????????Nested loop???????????HASH JOIN,?HASH JOIN????????????????? ????????subplan?????,???? pass?? ?join method???,?????STATISTICS COLLECTOR???cardinality?,???????HASH JOIN?????Nested Loop,????????????subplan?????access path; ???????Sales??????????????????,????HASH JOIN,??SUBPLAN??customers?????????;?????Nested Loop,???????cust_id?????Range Scan+Access by Rowid?

  • How to set _optimizer_search_limit and _optimizer_max_permutations in Oracle10g.

    - by user52856
    I am working on a product that must support both MSSQL and Oracle (10g and 11g). I have some very complex queries that seem to run without issue on MSSQL 2005/2008, but very, very slow with Oracle. The CPU on the oracle server skyrockets for long periods of time, and it seems like the optimizer may be trying to find the best execution plan for the very complex query. I did some Googling to figure out how to limit the amount of time the optimizer spends on this, and came up with _optimizer_search_limit and _optimizer_max_permutations. Both of these parameters are hidden in Oracle 10g, and setting them in init.ora doesn't seem to make any difference. How do I set these parameters in Oracle. Or am I just totally barking up the wrong tree with the assumption that the optimizer is spending several minutes finding an execution plan? Thanks.

  • Difference in VISUAL STUDIO VERSIONS

    - by karthik ram
    I would like to understand some fundamental VS version differences, What is the difference between Visual Studio 2008 and Visual Studio 2008 Team System? Does the Team System 2008 include VS2008, TFS 2008 & Team Explorer 2008? Furthermore, what is the difference betwene Team System 2008 and Team Suite 2008? I beleive there are no more Team Suites or Team Systems in 2010? Does Visual Studio Ultimate 2010 include all Team System components, like TFS 2010 & Team Explorer 2010, so in effect it is like an upgrade of Visual Studio 2008 Team System? Or does TFS 2010 & Team Explorer 2010 need to be installed separately?

  • Upgrade TFS 2010 build server to support .net 4.5

    - by JustEngland
    What is needed in the tfs 2010 build agent, to build .net 4.5 projects, in tfs 2008 we had to set the MSBuildPath property, but the configuration seems to be different in 2010. I get the following error message. (614): The imported project "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v11.0\WebApplications\Microsoft.WebApplication.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk. How we handled it in 2008 http://blogs.msdn.com/b/willbar/archive/2009/11/01/building-net-4-0-applications-using-team-build-2008.aspx

  • How to install a new TFS checkin policy on a TFS 2010 server?

    - by rayrayrayraydog
    We've recently upgraded our TFS server to TFS 2010 from 2008. We've been researching a couple new add-on checkin policies we want to install. The only problem is that all documentation I can find on adding new policies to the server appears to be specific to TFS 2008 or earlier. Those steps involve adding new keys in the registry which do not exist on our 2010 TFS server. Does anybody know where the process to install new checkin policies on a TFS 2010 server so they can be applied to Team Projects is documented? Thanks!

  • Code-First Database Creation During TFS 2010 CI Build

    - by jedimindtrickster
    I would like to automate code-first database generation during the automated CI build of a web project in Team Foundation Server 2010. When run locally the tests create a code-first database specified by the connection string in the app.config of the tests project. How do I configure the TFS Build Configuration to mimic this behaviour on the TFS build server? Edit The problem, it turns out, was that the TFS build server was successfully running the test which was using the default connection string in the app.config which pointed to the local SQL Server, not where I expected it. The solution was to use SlowCheetah on the TFS server as a means to transform the App.config file using the QA transform as per this blog article.

  • Can TFS 2010 be installed onto a single server and in a Workgroup (not AD)

    - by Pure.Krome
    Hi folks, currently, we're using TFS2010 at our office and we're about to move. Part of that move is a split of teams. Our team will get their own servers. So we need to build our own TFS server and add our current projects to that. Right now, our TFS server exists on TWO servers - one for TFS and one for our Continuous Integration .. i think that's a build controller or something. That really suxs for us - having TWO servers instead of one for all our source control. We love CI and how it works (after the massive massive pain it was to get our VS2010 solution to CI + web Deploy) ... but it does work. So - can we do this with ONE server? Also, we don't want to have an Active Directory. Will this also work?

  • How do you install a new build controller in TFS?

    - by JL.
    I am not looking for detailed instructions, I just want the quick and dirty overview. We have an existing TFS infrastructure, I am looking to install a new build controller for 1 team project. Do I need to create a new VM and install TFS (configure as controller) and then link it from the VM to the main TFS instance? OR Do I need to create the new VM, install TFS (configure as controller) and then - From the main TFS admin console on the main TFS server - add the new controller? Thanks in advance?

  • Clear/ Reset Result Table of Search page in OAF

    - by PRajkumar
    Normally problem faced by developers after creating Search Page is how to Clear/ Reset Result Table when developer open search page first time or after search when developer redirecting back to same search page from any other page (say delete page or update page)   Add following Code in your Search page Controller where you have constructed your Query Region   import oracle.apps.fnd.framework.webui.beans.layout.OAQueryBean; ... public void processRequest(OAPageContext pageContext, OAWebBean webBean) {  super.processRequest(pageContext, webBean);  OAQueryBean queryBean = (OAQueryBean)webBean.findChildRecursive("QueryRN");   // Here QueryRN is your Query Region Name as shown in following snap shot  queryBean.clearSearchPersistenceCache(pageContext); }     Note – After add this code, no need to worry about state of Application Module (AM). This code will clean up result table automatically every time when you will open Search page first time and when you are redirecting back to search page. But still as per good coding standard while redirecting back to search page always keep AM state to FALSE

  • How Social Is Your Contact Center?

    - by Charles Knapp
    More than 75% of consumers have complained on a social site after a poor customer experience. Yet, 70% of companies have little understanding of the social media conversations about their brand. To deliver upon your brand promise, retain customers, and increase their lifetime value, you must deliver great customer experiences across social, mobile, phone, and chat channels. Siloed channels produce poor customer experiences. Social channels must integrate with the people, processes, technology, and traditional channels used to satisfy customers. The more effective a company’s social marketing, the greater the demand for effective social service. However, service is not a job for social marketers. It is a job for service specialists, focused on KPIs such as response time, first contact resolution, satisfaction, churn, retention, and customer lifetime value. Most social-enabled contact centers are at the early adopter stage, attempting to “bolt on” social media as a side process. Many are experiencing inconsistent customer experiences, higher costs, and negligible return on investments. Service leaders should consider carefully how to integrate social channels with their current customer service and support people, processes, technology, and channels. Here is one company realizing success: the pre-integrated Oracle RightNow Social Experience “empowers our contact center operations by enabling our agents to join customer conversations that are happening on social sites like Twitter and Facebook and integrate those conversations into our overall multichannel customer engagement processes.” — Lisa Larson, Drugstore.com

  • Comments syntax for Idoc Script

    - by kyle.hatlestad
    Maybe this is widely known and I'm late to the party, but I just ran across the syntax for making comments in Idoc Script. It's been something I've been hoping to see for a long time. And it looks like it quietly snuck into the 10gR3 release. So for comments in Idoc Script, you simply [[% surround your comments in these symbols. %]] They can be on the same line or span multiple lines. If you look in the documentation, it still mentions making comments using the syntax. Well, that's certainly not an ideal approach. You're stuffing your comment into an actual variable, it's taking up memory, and you have to watch double-quotes in your comment. A perhaps better way in the old method is to start with my comments . Still not great, but now you're not assigning something to a variable and worrying about quotes. Unfortunately, this syntax only works in places that use the Idoc format. It can't be used in Idoc files that get indexed (.hcsp & .hcsf) and use the <!--$...--> format. For those, you'll need to continue using the older methods. While on the topic, I thought I would highlight a great plug-in to Notepad++ that Arnoud Koot here at Oracle wrote for Idoc Script. It does script highlighting as well as type-ahead/auto-completion for common variables, functions, and services. For some reason, I can never seem to remember if it's DOC_INFO_LATESTRELEASE or DOC_INFO_LATEST_RELEASE, so this certainly comes in handy. I've updated his plug-in to use this new comments syntax. You can download a copy of the plug-in here which includes installation instructions.

  • Agile PLM on Developing Agile PLM: Software Lifecycle Management

    - by Kerrie Foy
    Change is constant.  That saying couldn’t be truer when applied to software development.   And with all that change comes extensive product complexity.  How do you manage it all?  As software developers ourselves, we can certainly empathize with the challenge. On April 3, 2012 Stephen Van Lare, VP of PLM Product Development, hosted a webcast to share how Oracle uses Agile to develop Agile – a PLM solution for managing a PLM solution!   Stephen passionately shared his unique insight based on 10 years of using Agile PLM to manage the development process, as well as customer use cases.  He shared our time-proven view of the software’s relationship to the product record, while pointing out that PLM is not source control.  He began with the challenges of software development, which boiled down to the deduction that “despite many great tools in the software development industry, it takes a lot more than good source control, more than good bug tracking, to get to an on-time, on-budget and quality release in your marketplace.   It requires defining the right things you want to do, managing the scope, managing your schedule, and, most importantly, managing the change to all those things over the lifecycle of the process. And this is the definition of PLM.”   Stephen then defined the relationship of PLM to the software development process by detailing the two main use cases –  Product Lifecycle and Mechatronics – which can be used simultaneously and in fact are already used in most industries today.  The Product Lifecycle use case is used to manage artifacts and change throughout product development, while the Mechatronics use case involves the software, hardware and electrical design in the BOM.  In essence, PLM is just as relevant to software as the rest of the BOM when trying to maximize profits during any phase of the lifecycle. Please take the opportunity to watch Stephen Van Lare as he details how and why based on his own experience developing Agile with Agile, as well as a lively Q&A session, in the Software PLM Webcast Replay.
