• Does Your Customer Engagement Create an Ah Feeling?

  - by Richard Lefebvre

  An (Oracle CX Blog) article by Christina McKeon Companies that successfully engage customers all have one thing in common. They make it seem easy for the customer to get what they need. No one would argue that brands don’t want to leave customers with this “ah” feeling. Since 94% of customers who have a low-effort service experience will buy from that company again, it makes financial sense for brands.1 Some brands are thinking differently about how they engage their customers to create ah feelings. How do they do it? Toyota is a great example of using smart assistance technology to understand customer intent and answer questions before customers hit the submit button online. What is unique in this situation is that Toyota captures intent while customers are filling out email forms. Toyota analyzes the data in the form and suggests responses before the customer sends the email. The customer gets the right answer, and the email never makes it to your contact center — which makes you and the customer happy. Most brands are fully aware of chat as a service channel, but some brands take chat to a whole new level. Beauty.com, part of the drugstore.com and Walgreens family of brands, uses live chat to replicate the personal experience that one would find at high-end department store cosmetic counters. Trained beauty advisors, all with esthetician or beauty counter experience, engage in live chat sessions with online shoppers to share immediate advice on the best products for their personal needs. Agents can watch customer activity online and determine the right time to reach out and offer help, just as help would be offered in a brick-and-mortar store. And, agents can co-browse along with the customer helping customers with online check-out. These personal chat discussions also give Beauty.com the opportunity to present products, advertise promotions, and resolve customer issues when they arise. Beauty.com converts approximately 25% of chat sessions into product orders. Photobox, the European market leader in online photo services, wanted to deliver personal and responsive service to its 24 million members. It ensures customer inquiries on personalized photo products are routed based on agent knowledge so customers get what they need from the company experts. By using a queuing system to ensure that the agent with the most appropriate knowledge handles the query, agent productivity increased while response times to 1,500 customer queries per day decreased. A real-time dashboard prevents agents from being overloaded with queries. This approach has produced financial results with a 15% increase in sales to existing customers and a 45% increase in orders from newly referred customers.

• JavaScript: Code Folding

  - by Petr

  Today I would like to mentioned code folding in the new JavaScript editor support, which is available in the continual builds from our server. It's a basic feature, but was mentioned in a comment under the mentioned post. So you can fold comments and every code block between { and }. The current support allows only methods to be folded. The difference is shown below. In the picture on the left side is the current folding and on the right side the new one.   The code folding can be switched off in the Editor Options (Tools main menu -> Options -> Editor category -> General Tab). In this dialog you can also define which folds should be collapsed by default when you open a file. These options more closely fit Java editor needs, but you can see in the next picture how the options are mapped for JavaScript code.  The Method option folds all functions in the code. Other code blogs are fold through the option Tags and Other Code Blogs.  The documentation comments (starts with /**) are fold through Javadoc Comments and when you check Initial Comment, then all comments that start with /* are folded by default.  The new JavaScript editor also supports custom folds. To add your custom fold, type in two special comments as shown in this example: // <editor-fold> Your code goes here... // </editor-fold> You can define the default description of a collapsed fold by adding a "desc" attribute: // <editor-fold desc="This is my super secret genius code."> Your code goes here... // </editor-fold> You can set a fold to be collapsed by default by adding a "defaultstate" attribute: // <editor-fold defaultstate="collapsed"> Your code goes here... // </editor-fold> There is a code template that helps with writing custom fold comments. The abbreviation for the template is fcom. As I wrote the new JS support is available in the continual builds. Go here for more info.

• JNDI Datasource Problem on Tomcat 6, Hibernate

  - by Asuman AKYILDIZ

  Hello; I am using Tomcat 6 as application server, Struts-Hibernate and MyEclipse 6.0. My application uses JDBC driver but I should modify it to use JNDI Datasource. I followed steps as described in tomcat 6.0 howto tutorial. I defined my resource in tomcatconf: <Resource name="jdbc/ats" global="jdbc/ats" auth="Container" type="javax.sql.DataSource" driverClassName="oracle.jdbc.OracleDriver" url="jdbc:oracle:thin:@//localhost:1521/MISDEV" username="TEST" password="TEST" maxActive="20" maxIdle="10" maxWait="-1" validationQuery="SELECT 1 from dual" removeAbandoned="true" removeAbandonedTimeout="30" logAbandoned="false"/> I gave reference in my application web.xml: <resource-ref> <description>Oracle Datasource example</description> <res-ref-name>jdbc/ats</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> And I defined datasource-dialect in my hibernate-cfg.xml <property name="connection.datasource">java:comp/env/jdbc/ats</property> <property name="dialect">org.hibernate.dialect.Oracle9Dialect</property> But when I create hibernate session, it can not open the connection: 09:18:11,322 ERROR JDBCExceptionReporter:72 - Connections could not be acquired from the underlying database! org.hibernate.exception.GenericJDBCException: Cannot open connection I also tried to set the properties at runtime: Configuration configuration = new Configuration(); configuration.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle9Dialect"); //configuration.setProperty("hibernate.connection.datasource", "java:comp/env/jdbc/ats"); configuration.setProperty("hibernate.current_session_context_class", "thread"); configuration.setProperty("hibernate.connection.provider_class", "org.hibernate.connection.C3P0ConnectionProvider"); configuration.setProperty("hibernate.show_sql", "true"); sessionFactory = configuration.configure().buildSessionFactory(); It does not open connection again. But, when I use JDBC driver it works: Configuration configuration = new Configuration(); configuration.setProperty("hibernate.dialect", "org.hibernate.dialect.Oracle9Dialect"); //configuration.setProperty("hibernate.connection.datasource", "java:comp/env/jdbc/ats"); configuration.setProperty("hibernate.connection.url", "jdbc:oracle:thin:@//localhost:1521/MISDEV"); configuration.setProperty("hibernate.connection.username", "test"); configuration.setProperty("hibernate.connection.password", "test"); configuration.setProperty("hibernate.connection.driver_class", "oracle.jdbc.OracleDriver"); configuration.setProperty("hibernate.transaction.factory_class", "org.hibernate.transaction.JDBCTransactionFactory"); configuration.setProperty("hibernate.current_session_context_class", "thread"); configuration.setProperty("hibernate.connection.provider_class", "org.hibernate.connection.C3P0ConnectionProvider"); configuration.setProperty("hibernate.show_sql", "true"); sessionFactory = configuration.configure().buildSessionFactory(); I have been searching for 3 days and no success. What may be de problem?

• What do you think of the EntLib 5.0 configuration tool?

  Hello again! Its been a while, I know. Ive been busy over the last few months with several projects, some of them software related, and one of them human my son Jesse was born on 26 February 2010. Fun times! Meanwhile, back in Redmond, the p&p team has been busy working on Enterprise Library 5.0 see Grigoris announcement for details on the beta. Theres a ton of new stuff in this release, but theres one big new feature that hasnt received a lot of attention that Im keen to hear your perspectives on. The change is the biggest overhaul to the configuration tool since Enterprise Library was launched. If you havent yet grabbed the EntLib 5.0 beta, heres a before and after shot of the config tool: Enterprise Library 4.1 config tool Enterprise Library 5.0 (beta 1) config tool The tool has been rebuilt from the ground up in response to some feedback and usability studies from the previous version of the tool. But is this a step in the right direction? Id love to hear what you think. If youve downloaded EntLib 5.0 and tried out the tool, please share your thoughts on: First impressions. Is the tool easy to understand? Easy to find what youre looking for? Easy to read existing configuration? Pretty? Ease of use for real life tasks. Rather than make up your own tasks, here are a few sample scenarios you might want to try: Configure the data access block with a SQL Server connection called Audit that points to a database called Audit on a server called DB Configure the logging block so that any log entries in the Audit category are written to both the Event Log and the Audit database (see above) Configure the validation block with a ruleset called Email Address that uses an appropriate regular expression for e-mail addresses Configure the policy injection block such that any calls to classes in the MyCompany.Security namespace are logged before and after the call using the Audit category (see above) Comparison with the old config tool. What do you like better in the new tool? What did you like better in the old tool? How do you rate your level of expertise using the old tool? Keep in mind that I no longer work in the p&p team, so I cant say how any of this feedback will be used (although Im sure the team is listening!). However since Ive invested so much time in Enterprise Library, both in leading the team and using the product on real projects Im very interested to hear what you all think of the tools new direction.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Book review: Peopleware: Productive Projects and Teams

  - by DigiMortal

     Peopleware by Tom DeMarco and Timothy Lister is golden classic book that can be considered as mandatory reading for software project managers, team leads, higher level management and board members of software companies. If you make decisions about people then you cannot miss this book. If you are already good on managing developers then this book can make you even better – you will learn new stuff about successful development teams for sure. Why peopleware? Peopleware gives you very good hints about how to build up working environment for project teams where people can really do their work. Book also covers team building topics that are also important reading. As software developer I found practically all points in this book to be accurate and valid. Many times I have found my self thinking about same things and Peopleware made me more confident about my opinions. Peopleware covers also time management and planning topics that help you do way better job on using developers time effectively by minimizing the amount of interruptions by phone calls, pointless meetings and i-want-to-know-what-are-you-doing-right-now questions by managers who doesn’t write code anyway. I think if you follow suggestions given by Peopleware your developers are very happy. I suggest you to also read another great book – Death March by Edward Yourdon. Death March describes you effectively what happens when good advices given by Peopleware are totally ignored or worse yet – people are treated exactly opposite way. I consider also Death March as golden classics and I strongly recommend you to read this book too.

• LCM says Smart List import is complete but actually its not...Here are probable reasons

  - by RahulS

  First of all some basics of smart list: Administrators use Smart Lists to create custom drop-down lists that users access from data form cells. When clicking in cells whose members are associated with a Smart List (as a member property), users select items from drop-down lists instead of entering data. Users cannot type in cells that contain Smart Lists. Smart Lists display in cells as down arrows that expand when users click into the cells. Below link will give you more information on Smart Lists: http://download.oracle.com/docs/cd/E17236_01/epm.1112/hp_admin/enum_pg.html I got a simple query today, "The LCM process generates and indicates a status of "Complete", however, the 3,018 records do not appear in the Planning application. No error exists in the log to identify the problem." Things which can be checked in this case: 1. Spaces are not allowed in the Entry Name, 2. Spaces are allowed in the Entry Label, 3. The name must start with an alpha character or underscore, 4. Valid characters for the remaining part of the name must be alpha, numeric, or an underscore, 5. Enter a name that is unique within the smart list, 6. I am not sure about the limits but I have seen 22,000 members loaded fine, 7. ID for every entry should be unique,  8. IDs need not to be consecutive, Ex: It was go from 1 to 100 then 500 to 900 then 1900 to 4500 etc. While import .xml file using LCM there were no errors in the foundation and LCM migration logs, but when checked in the HyS9PlanningSysErr.log, few errors were found:Ex: The name Data_Coord_(Prod)_ACS is invalid, The name Sr_Dir_b+Medcd_Gvt_Rel_Sls_Mkt is invalid, The name entered is invalid. Enter a name that is unique within the smart list, Also, we can Load Smart List dimensions and Smart List dimension entries using the /DS:HSP_SMARTLISTS parameter in outlineload utility: OutlineLoad /A:acpt /U:admin /M /I:c:/smartlist_create1.csv /DS:HSP_SMARTLISTS /L:c:/OutlineLogs/outlineLoad.log /X:c:/OutlineLogs/outlineLoad.exc SmartList Name, Operation, Label, Display Order, Missing Label, Use Form Missing Label, Entry ID, Entry Name, Entry Label SL1,addsmartlist,SL1Label,,,,,, SL1,addEntry,,,,,,entry1,entrylabel1 SL1,addEntry,,,,,,entry2,entrylabel2 Cheers..!!!

• How to integrate Java ME SDK 3.2 with NetBeans

  - by SungmoonCho

  Many people like to use Java ME SDK with IDEs. We provided instructions on how to integrate the SDK with NetBeans through the download page, and also through the release note, however, let me explain it here once again with some screen shots. 1. Download Java ME SDK and NetBeans plugin from here. 2. Install Java ME SDK first. You will have the emulator and the runtime on your machine. Also please unarchive the NetBeans plugin somewhere. 3. Launch NetBeans. 4. Go to "Tools" - "Plugins". 5. Check out the "Installed" tab. Check "Show details". If you see the previous version of Java ME SDK Tools installed already. Check those to uninstall them. 6. Go to "Settings" tab. 7. Click "Add", and provide the location of NetBeans plugin. In my case, it is "file:/C:/Users/sungcho/Downloads/nb-me-sdk-plugins-uc/updates.xml". Don't forget to add "updates.xml" at the end. 8. Click "Okay" 9. Click "Available Plugins" tab. 10. If you scroll down, you will see three Java ME SDK Tools. Check "Java ME SDK Tools" plugin. Also check others as you desire. 11. Follow the instruction and install them. 12. Restart NetBeans 13. That is it. Done. Now you will see Oracle Java ME SDK 3.2 in your Java Platform list.

• Transfer ownership of abandoned Google Analytics account

  - by Bobe

  The web team of a new client was fully responsible for the client's Google Analytics account, meaning the client didn't keep records of the account. Now that that web team has gone under we are trying to retrieve the account. Is it possible to request an account to be transferred to another owner, or alternatively have a full-privileged user added to the account? What steps should I take to resolve this issue with Google?

• Synchronizing ODSEE and OUD

  - by Etienne Remillon

  When it comes to synchronizing between ODSEE and OUD, what should be the best options ? Couple  options are available - Use one of OUD internal capability called Replication Gateway - Use our synchronization tool called Directory Integration Platform part of Oracle Directory Services Plus - Manuel export and import Let's check pro and cons on each method. Replication Gateway is the natural, out of the box solution to perform the task. We created this as a feature of OUD because it works at our replication protocol level. The gateway perform the required adaptation between the ODSEE's replication protocol and OUD's one. The benefits of doing this is that it provide strong consistency between the to type of directories. This fully leverage conflict management implemented in the replication protocols to ensure that changes are applied in a coherent and ordered manner. It does not require specific modification on existing ODSEE production instances such as turning on "retro changelog". Changes are propagated at near speed of replication in both directions. Replication Gateway can also synchronize information that are stored internally in the directory server such as "xxxxx" account locking managed at ODSEE server level and not via the nsyyyy attribute. OUD replication gateway does no require any specific tools or installation specific procedure. It is manged like other OUD component with monitoring and configuration via the standard console. OUD Replication Gateway does not perform adaptation between ODSEE and OUD. Using Directory Integration Protocol as external component to OUD, brings flexibility in remapping and transformations between ODSEE and OUD. There is a price to pay in using DIP to perform the synchronization task. You will have to turn on the retro change log to get access to changes on the ODSEE side (this will impact disk and CPU usage and performances which could be a serious challenge for your existing ODSEE environment (if you have not provisioned additional hardware and instances). You will not benefits of conflict resolution management and this might have to be addressed at application level, which is not always possible to implement. Using export and import seams very simple, but this methodology cannot ensure an highly available deployment with up to date entries on booth sides. This solution can be used if full HA with up-to-date data is not needed (during synchronization time). It often used  if data-cleaning need to take place to avoid polluting a new environment with old un-necessary data.

• Is there a tool that allows site users to schedule meetings with each other? [closed]

  - by Andrew Min

  I'm the webmaster for a debate team, and we're trying to find a tool that allows us to have multiple team members say when they're available and see who else is available during those timeslots for one-on-one practice rounds. I suppose we could use something like Doodle, but that would involve recreating the Doodle every week. There are many scheduling tools available, but they're usually built so that you can sign up to meet with a specific individual (think a doctor or a professor's office hours), whereas you could be paired with ANY individual.

• OWB 11gR2 &ndash; OMB and File Editing

  - by David Allan

  Here we will see how we can use the IDE for editing OMB scripts. The 11gR2 release is based on the common Oracle platform IDE used also by JDeveloper. It comes with a bunch of standard behavior for editing and rendering code. One of the lesser known things is that if you drop a text file into OWB you can edit it. So you can drop your tcl scripts right into OWB and edit in-place, and don’t need another IDE like Eclipse just for this task. Cool, so you have the file here. There may be no line numbers, you can toggle line numbers on by right clicking in the gutter. If we edit the file within the OWB IDE, the save is a little different from normal. OWB doesn’t normally manipulate files so things like ctrl-s to save, saves the OWB objects, but if you edit a file the closing of the file will ask if you want to save it – check it out. Now we enter the realm of ‘he who dares’…. Note the IDE doesn’t know about tcl files out of the box, so you see above there is no syntax highlighting. The code is identified by the extension… .java is java, .html is HTML etc. With OWB, the OMB scripts are tcl, we usually have .tcl extension on these files. One of the things we can do to trick up the syntax highlighting is to simply rename the file to have a .java suffix, then all of a sudden we get syntax highlighting, see the illustration here where side by side we see a the file with a .java extension and a .tcl extension. Not ideal pretending to be .java but gets us a way to having something more useful than notepad. We can then change the syntax highlighting such that we get Eclipse like highlighting within the IDE from the Tools Preferences option; You then get the Eclipse like rendering albeit using a little tweak on the file names… Might be useful if you are doing any kind of heavy duty OMB script development and just want a single IDE. The OMBPlus panel is then at hand for executing and testing it out.

• SQL Server is now supported by phpBB!

  - by The Official Microsoft IIS Site

  Our team is really excited to announce the new release of phpBB 3.0.7-PL1 by the phpBB community that supports SQL Server, and one can download it from the Web Application Gallery for a very easy install!! But let’s step back for a moment and provide some background. Microsoft’s Interoperability team has been working with a few PHP projects to support SQL Server using our driver, phpBB was one of them. Although phpBB already had some support for SQL Server / Access, our 1.1 release driver offered...(read more)

• SOASuite 11.1.1.4 : Error Logging into BPM11g Composer?

  - by angelo.santagata

  Hey all, I’ve just installed SOA Suite 11.1.1.4 and noticed a few funnies which people might hit, thankfully each of them have an easy solution.   1. Some applications are installed but dont appear to work? If when you install SOASuite you may notice that the following applications dont appear to work, however they do appear as deployments in Weblogic Server Console e.g.  SOA Composer (composer), FMW Welcome Page Application (11.1.0.0.0) and some of the adaptors. If they appear in the deployments list state as “installed” and not Active, then its likely that they haven't been targeted to a specific server.   The solution is to target the application the desired managed server , e.g. AdminServer in a development environment. This is done by selecting the application, tab “Targets”, select all components, Button[change Targets] and select the appropriate server. This change can be done without restarting the Weblogic Server 2. You might find that when you try to log into the BPM Composer at http://machine:7001/bpm/composer , the login screen will appear but you cant log in. The error log might mention the following   The solution to this is two fold, a) When creating the domain, avoid using 127.0.0.1 as the Listener address, or “Any Addresses”, if this is a development machine create an alias in your /etc/hosts file and then use this alias in the domain creation wizard. e.g.   my host file contains an entry     mypc     127.0.0.1   And in the Fusion middleware Configuration wizard   Twill then work!   if it still doesnt you can try setting the ServerURL attribute to http://mypc in the SoaInfraMBean instead of blank. This is accomplished by using Enterprise Manager. Use the System MBean Browser to navigate to Application Defined MBeans->oracle.as.soainfra.config->[ server]->SoaInfraConfig->soa-infra. Then changing the value of 'ServerURL' to http://mypc   Failing that give support a call….

• Visual Studio Extension: Web Essentials

  - by BizTalk Visionary

  To quote Scott Hanselman…. Visual Studio 2010 is really extensible and that's allowed many folks on the team to try out new features for Web Development without having to rebuild Visual Studio itself. One of those "playground" extensions is called "Web Essentials" by Mads Kristensen. Mads handles HTML5 and CSS3 tools for our team. You might remember Mads from when we released the Web Standards Update a few months back. Get it here: Scott Nanselman blog...

• JavaOne: Parleys.com, Spring Vs. Java EE and HTML5 tooling

  - by delabassee

  Parleys.com, a 2012 Duke's Choice Award winner, is an E-Learning platform that host content from different sources (conferences, JUGs meetings, etc.). There is a lot of technical content available for online but also offline consumption, including many sessions on Java EE. Parleys has just released, for free, all the Devoxx 2011 sessions (video and slides sync'ed!). From a technical point of view, Parleys.com is interesting as they have switched from Spring to Java EE 6 to avoid being locked in a proprietary framework. During the GlassFish Community BoF, Stephan Janssen (Parleys.com and Devoxx founder) also presented how GlassFish is used to support 2000 concurrent Parleys users over a cluster of 2 GlassFish instances. Talking about Java EE and/or Spring, Harshad Oak has posted an update on the 'Spring Vs. Java EE' panel discussion that took place on Tuesday. As Arun said standards such as Java EE does not necessarily refrain innovation: "JBoss Forge & Arquillian from RedHat are great examples of innovation in the JavaEE community. Standardization is important but innovation does continue even within that framework." Simplicity, productivity along with HTML5 are the driving themes of Java EE 7. In terms of simplicity and productivity, the developer experience can also be improved by the tooling. Every NetBeans release comes with a large set of improvements, the just released NetBeans 7.3 beta is no exception. The goal of ‘NB 7.3’s Project Easel’ is to improve HTML5 development, something that will be handy for Java EE 7 developers. Project Easel can, for example, communicate directly to Chrome's WebKit engine, this feature was shown during Sunday's Technical Keynote at the end of the Java EE section. In this beta release, Chrome and the embedded JavaFX browser are the only supported browsers but the NetBeans team plan to add support, over time, for other WebKit based browsers. NetBans 7.3 beta NetBeans 7.3 screenscasts Today (i.e. Wednesday 3rd) is also the final exhibition day, so make sure to visit the Java EE and the GlassFish pods on the Java DEMOgrounds (Hilton Grand Ballroom, 9:30 am - 5:00 pm). Finally, here are some Java EE and GlassFish related activities worth attending today if you are at JavaOne : Wednesday October 3rd Time Title Location 8:30-9:30am What's New in Servlet 3.1: An Overview Parc 55 Mission 8:30-9:30am Bean Validation 1.1: What's New Under the Hood Parc 55Cyril Magnin II/III 10:00-11:00am JSR 353: Java API for JSON Processing Parc 55 Mission 10:00-12:00pm Tutorial : Integrating Your Service into the GlassFish PaaS Platform Parc 55 Devisidero 11:30-12:30pm What's New in JSF: A Complete Tour of JSF 2.2 Parc 55Cyril Magnin I 11:30-12:30pm Best of Both Worlds: Java Persistence with NoSQL and SQL Parc 55 Mission 1:00-2:00pm Sharding Middleware to Achieve Elasticity and High Availability in the Cloud Parc 55Market Street 1:00-2:00pm Pimp My RESTful Java Applications Parc 55Cyril Magnin I 3:00-4:00pm Migrating Spring to Java EE Parc 55Cyril Magnin II/III 4:30-5:30pm JavaEE.Next(): Java EE 7, 8, and Beyond Parc 55Cyril Magnin II/III 4:30-5:30pm HTML5 WebSocket and Java Parc 55Cyril Magnin I 4:30-5:30pm Easy Middleware for Your Embedded Device Nikko Ballroom II/III

• Latency Matters

  - by Frederic P

  A lot of interest in low latencies has been expressed within the financial services segment, most especially in the stock trading applications where every millisecond directly influences the profitability of the trader. These days, much of the trading is executed by software applications which are trained to respond to each other almost instantaneously. In fact, you could say that we are in an arms race where traders are using any and all options to cut down on the delay in executing transactions, even by moving physically closer to the trading venue. The Solaris OS network stack has traditionally been engineered for high throughput, at the expense of higher latencies. Knowledge of tuning parameters to redress the imbalance is critical for applications that are latency sensitive. We are presenting in this blog how to configure further a default Oracle Solaris 10 installation to reduce network latency. There are many parameters in fact that can be altered, but the most effective ones are intr_blank_time and intr_blank_packets. These parameters affect on-board network throughput and latency on Solaris systems. If interrupt blanking is disabled, packets are processed by the driver as soon as they arrive, resulting in higher network throughput and lower latency, but with higher CPU utilization. With interrupt blanking disabled, processor utilization can be as high as 80–90% in some high-load web server environments. If interrupt blanking is enabled, packets are processed when the interrupt is issued. Enabling interrupt blanking can result in reduced processor utilization and network throughput, but higher network latency. Both parameters should be set at the same time. You can set these parameters by using the ndd command as follows: # ndd -set /dev/eri intr_blank_time 0 # ndd -set /dev/eri intr_blank_packets 0 You can add them to the /etc/system file as follows: set eri:intr_blank_time 0 set eri:intr_blank_packets 0 The value of the interrupt blanking parameter is a trade-off between network throughput and processor utilization. If higher processor utilization is acceptable for achieving higher network throughput, then disable interrupt blanking. If lower processor utilization is preferred and higher network latency is the penalty, then enable interrupt blanking. Our experience at ISV Engineering is that under controlled experiments the above settings result in reduction of network latency by at least 50%; on a two-socket 3GHz Sun Fire X4170 M2 running Solaris 10 Update 9, the above settings improved ping-pong latency from 60µs to 25-30µs with the on-board NIC.

• Can't save data for a member in a data form

  - by RahulS

  Implied sharing is an old thing everyone knows the reasons and solutions of that, still little theory about that: With Essbase implied sharing, some members are shared even if you do not explicitly set them as shared. These members are implied shared members. When an implied share relationship is created, each implied member assumes the other member’s value. Essbase assumes (or implies) a shared member relationship in these situations: 1. A parent has only one child 2. A parent has only one child that consolidates to the parent In a Planning form that contains members with an implied sharing relationship, when a value is added for the parent, the child assumes the same value after the form is saved. Likewise, if a value is added for the child, the parent usually assumes the same value after a form is saved.For example, when a calculation script or load rule populates an implied share member, the other implied share member assumes the value of the member populated by the calculation script or load rule. The last value calculated or imported takes precedence. The result is the same whether you refer to the parent or the child as a variable in a calculation script. For more information have a look at: http://docs.oracle.com/cd/E17236_01/epm.1112/hp_admin_11122/ch14s11.html Now the issue which we are going to talk about is We loose data on save even when the parent is dynamic calc and has a single child. A dynamic calc parent to a single child:  If we design the form with following selection: In the data form we will find parent below the member and this is by design whenever you make a selection using commands to select all the member below parent, always children will appear before the parent: Lets try to enter data, Save it Now, try to change the way we selected members Here we go: Now the question again why this behavior: 1. Data from Planning data form passes to Essbase row by row, 2. Because in data form the child member appears before the parent, 3. First, data goes to Essbase for child (SingleStoreChild), 4. Then when Planning passes the data for parent there was #Missing or No data,  5. Over writes the data to #missing. PS: As we know that dynamic calc members are calculated on the fly they are not allocated with any memory in the Essbase, here the parent was dynamic calc and it was pointing to same memory as child in the background, when Planning was passing data to Essbase for second row it has updated the child with missing data.(Little confusing, let me know if you need more explanation) 6. As one of the solutions just change the order of appearance of parent and child. Cheers..!!! Rahul S. https://www.facebook.com/pages/HyperionPlanning/117320818374228
