  • Remote Debugging

    - by Pemdas
    Obviously, the easiest way to solve a bug is to be able to reproduce it in house. However, sometimes that is not practical. For starters, users are often not very good at providing you with useful information. Costumer Service: "what seems to be the issue?" User: "It crashed!" To further compound that, sometimes the bug only occurs under certain environmentally conditions that can not be adequately replicated in house. With that in mind, it is important to build some sort of diagnostic framework into your product. What type of solutions have you seen or used in your experience? Logging seems to be the predominate method, which makes sense. We have a fairly sophisticated logging frame work in place with different levels of verbosity and the ability to filter on specific modules (actually we can filter down to the granularity of a single file). Error logs are placed strategically to manufacture a pretty good representation of a stack trace when an error occurs. We don't have the luxury of 10 million terabytes of disk space since I work on embedded platforms, so we have two ways of getting them off the system: a serial port and a syslog server. However, an issue we run into sometimes is actually getting the user to turn the logs on. Our current framework often requires some user interaction.

  • ODI 11g - Faster Files

    - by David Allan
    Deep in the trenches of ODI development I raised my head above the parapet to read a few odds and ends and then think why don’t they know this? Such as this article here – in the past customers (see forum) were told to use a staging route which has a big overhead for large files. This KM is an example of the great extensibility capabilities of ODI, its quite simple, just a new KM that; improves the out of the box experience – just build the mapping and the appropriate KM is used improves out of the box performance for file to file data movement. This improvement for out of the box handling for File to File data integration cases (from the 11.1.1.5.2 companion CD and on) dramatically speeds up the file integration handling. In the past I had seem some consultants write perl versions of the file to file integration case, now Oracle ships this KM to fill the gap. You can find the documentation for the IKM here. The KM uses pure java to perform the integration, using java.io classes to read and write the file in a pipe – it uses java threading in order to super-charge the file processing, and can process several source files at once when the datastore's resource name contains a wildcard. This is a big step for regular file processing on the way to super-charging big data files using Hadoop – the KM works with the lightweight agent and regular filesystems. So in my design below transforming a bunch of files, by default the IKM File to File (Java) knowledge module was assigned. I pointed the KM at my JDK (since the KM generates and compiles java), and I also increased the thread count to 2, to take advantage of my 2 processors. For my illustration I transformed (can also filter if desired) and moved about 1.3Gb with 2 threads in 140 seconds (with a single thread it took 220 seconds) - by no means was this on any super computer by the way. The great thing here is that it worked well out of the box from the design to the execution without any funky configuration, plus, and a big plus it was much faster than before, So if you are doing any file to file transformations, check it out!

  • Named output parameters vs return values

    - by Abyx
    Which code is better: // C++ void handle_message(...some input parameters..., bool& wasHandled) void set_some_value(int newValue, int* oldValue = nullptr) // C# void handle_message(...some input parameters..., out bool wasHandled) void set_some_value(int newValue, out int oldValue) or bool handle_message(...some input parameters...) ///< Returns -1 if message was handled //(sorry, this documentation was broken a year ago and we're too busy to fix it) int set_some_value(T newValue) // (well, it's obvious what this function returns, so I didn't write any documentation for it) The first one doesn't have and need any documentation. It's a self-documenting code. Output value clearly says what it means, and it's really hard to make a change like this: - void handle_message(Message msg, bool& wasHandled) { - wasHandled = false; - if (...) { wasHandled = true; ... + void handle_message(Message msg, int& wasHandled) { + wasHandled = -1; + if (...) { wasHandled = ...; With return values such change could be done easily /// Return true if message was handled - bool handle_message(Message msg) { + int handle_message(Message msg) { ... - return true; + return -1; Most of compilers don't (and can't) check documentation written in comments. Programmers also tend to ignore comments while editing code. So, again, the question is: if subroutine has single output value, should it be a procedure with well-named self-documenting output parameter, or should it be a function which returns an unnamed value and have a comment describing it?

  • How do I get Graphics drivers / bluetooth / card reader working on an Acer Aspire V3-571G?

    - by Adam
    A couple of days ago I bought an Acer Aspire V3-571G laptop without a system installed on it. The only thing that was there was Linux Linpus. I created a bootable CD with Ubuntu 12.04 64-bit - I read that my processor was 64 bit and that it might be a good configuration for my gear (I'm not especially fluent with all the computer stuff, still trying to learn) and replaced Linpus with Ubuntu. Everything seemed to work fine, but there're few exceptions to that which came pass my way. My bluetooth doesn't work. It seems to be switched on, but when I check my system settings the button is actually off, and I can't drag it 'perminently' to the 'on' position. Tried a couple of commands I found on the net, none of them helped and there was no word whatsoever in my BIOS settings about enabling bluetooth. My card reader has some serious problems with copying more than one file at a time. I tried to put some music on my phone through a MicroSD card adapter (because my bluetooth doesn't work) and it got stuck every single time I copied an album on it. I'm not sure if all my drivers were properly installed, so I checked in the terminal if it could tell me sth about my graphics. typed: sudo lshw -c display and what i got was: *-display UNCLAIMED description: VGA compatible controller product: NVIDIA Corporation vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller cap_list configuration: latency=0 resources: memory:b2000000-b2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:2000(size=128) *-display description: VGA compatible controller product: Ivy Bridge Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:44 memory:b3000000-b33fffff memory:c0000000-cfffffff ioport:3000(size=64) As I said I'm no expert and not english-speaking generally, but it doesn't seem to be right.

  • Ping Access to a Nested VM !! Plz Help

    - by Shivaramakrishnan
    I have a problem in communication between the host and the nested VM.This is my layout. I have installed KVM on host machine having a single nic interface (public ip) running Ubuntu.On top of this,I have VM running Ubuntu.I have installed KVM in this VM too.I then have a VM inside this running a web server. I am able to ping the host from this web server VM and ssh into it.But from host to VM ,ping is being unsuccessful. The VM (named L1hyp) on host was created using libvirt-manager and has IP of 192.168.122.8. The vswitch interface created at host is in default config (NAT-ed). Its IP is 192.168.122.1. Now this VM is also having a vswitch interface which is in default config (NAT-ed).Its IP is 192.168.100.1. The Web server VM is created on top of this L1hyp VM, is having an IP of 192.168.100.186. The Webserver VM uses 192.168.100.1 as its default gw. The L1hyp uses 192.168.122.1 as its default gw. From Host: ping 192.168.122.8 - SUCCEEDS ping 192.168.122.1 - SUCCEEDS ping 192.168.100.1 - SUCCEEDS ping 192.168.100.186 - FAILS Comes up with Destination Host Unreachable From 192.168.122.1. But there is route to 192.168.100.0/24 subnet from host.Ping to 192.168.100.1 succeeds. From Webserver VM: ping 192.168.100.1 - SUCCEEDS ping 192.168.122.1 - SUCCEEDS SSH from web server VM to host succeeds. Can anyone help me out what needs to be modified to have two way communication between the host and Webserver VM at the earliest? I am pondering over this problem for over a week now.

  • Antenna Aligner Part 3: Kaspersky

    - by Chris George
    Quick one today. Since starting this project, I've been encountering times where Nomad fails to build my app. It would then take repeated attempts at building to then see a build go through successfully. Rob, who works on Nomad at Red Gate, investigated this and it showed that certain parts of the message required to trigger the 'cloud build' were not getting through to the Nomad app, causing the HTTP connection to stall until timeout. After much scratching heads, it turns out that the Kaspersky Internet Security system I have installed on my laptop at home, was being very aggressive and was causing the problem. Perhaps it's trying to protect me from myself? Anyway, we came up with an interim solution why the Nomad guys investigate with Kaspersky by setting Visual Studio to be a trusted application with the Kaspersky settings and setting it to not scan network traffic. Hey presto! This worked and I have not had a single build problem since (other than losing internet connection, or that embarrassing moment when you blame everyone else then realise you've accidentally switched off your wireless on the laptop).

  • Speeding up ROW_NUMBER in SQL Server

    - by BlueRaja
    We have a number of machines which record data into a database at sporadic intervals. For each record, I'd like to obtain the time period between this recording and the previous recording. I can do this using ROW_NUMBER as follows: WITH TempTable AS ( SELECT *, ROW_NUMBER() OVER (PARTITION BY Machine_ID ORDER BY Date_Time) AS Ordering FROM dbo.DataTable ) SELECT [Current].*, Previous.Date_Time AS PreviousDateTime FROM TempTable AS [Current] INNER JOIN TempTable AS Previous ON [Current].Machine_ID = Previous.Machine_ID AND Previous.Ordering = [Current].Ordering + 1 The problem is, it goes really slow (several minutes on a table with about 10k entries) - I tried creating separate indicies on Machine_ID and Date_Time, and a single joined-index, but nothing helps. Is there anyway to rewrite this query to go faster?

  • Update to SQL Server Configuration Scripting Utility

    - by Bill Graziano
    Last spring I released a utility to script SQL Server configuration information on CodePlex.  I’ve been making small changes in this application as my needs have changed.  The application is a .NET 2.0 console application.  This utility serves two needs for me.  First it helps with disaster recovery.  All server level objects (logins, jobs, linked servers, audits) are scripted to a single file per object type.  This enables the scripts to be easily run against a DR server.  If these are checked into source control you can view the history of the script and find out what changed and when. The second goal is to capture what changed inside a database.  Objects inside a database (tables, stored procedures, views, etc.) are each scripted to their own file.  This makes it easier to track the changes to an object over time.  This does include permissions and role membership so you can capture security changes.  My assumption is that a database backup is the primary method of disaster recovery for databases so this utility is designed to capture changes to objects.  You can find the full list of changes from the original on the Downloads page on CodePlex.

  • Which web site gives the most accurate indication of a programmer's capabilities?

    - by Jerry Coffin
    If you were hiring programmers, and could choose between one of (say) the top 100 coders on topcoder.com, or one of the top 100 on stackoverflow.com, which would you choose? At least to me, it would appear that topcoder.com gives a more objective evaluation of pure ability to solve problems and write code. At the same time, despite obvious technical capabilities, this person may lack any hint of social skills -- he may be purely a "lone coder", with little or no ability to help/work with others, may lack mentoring ability to help transfer his technical skills to others, etc. On the other hand, stackoverflow.com would at least appear to give a much better indication of peers' opinion of the coder in question, and the degree to which his presence and useful and helpful to others on the "team". At the same time, the scoring system is such that somebody who just throws up a lot of mediocre (or even poor answers) will almost inevitably accumulate a positive total of "reputation" points -- a single up-vote (perhaps just out of courtesy) will counteract the effects of no fewer than 5 down-votes, and others are discouraged (to some degree) from down-voting because they have to sacrifice their own reputation points to do so. At the same time, somebody who makes little or no technical contribution seems unlikely to accumulate a reputation that lands them (even close to) the top of the heap, so to speak. So, which provides a more useful indication of the degree to which this particular coder is likely to be useful to your organization? If you could choose between them, which set of coders would you rather have working on your team?

  • How do you KISS?

    - by Conor
    The KISS principle is a highly quoted design mantra. The aim of this principle is to stamp out unnecessary complexity on a project. This is a good thing, saving time, energy and money. It can lead to a relatively stress free implementation and a simple, elegant, maintainable end product. A lot of discussion on KISS provides mechanisms to simplify requirements, design and implementation. Things that spring to mind include: avoid scope creep; simple obvious design and code; minimal run-time dependencies; refactoring to maintain simplicity; etc. However there are a lot of implicit things that we do to KISS. Examples: small team sizes; minimal management layers; tidy desk; mastery of a single IDE; clear concise error messages; scripts to automate/encapsulate tasks; etc Why KISS practices do you apply? How have they been of benefit? I'm especially interested in non-obvious practices.

  • IIS 7 - Application pools

    - by vikp
    I made a CompanySite website in IIS - it's the only website on that server. I created .NET 4 Integrated pool for that website. I've installed ASP.Net site into CompanySite and it works fine. Now I'd like to install an application within this site. I create another .NET 4 application pool for that application. Then I install application into CompanySite using that application pool. As soon as setup starts off the website goes offline either with 503 or with The page cannot be displayed because an internal server error has occurred. The only way to fix this (that I have found) is to uninstall that application and restart Windows Server, not just IIS server. Question is how can I install multiple applications within a single site? THank you

  • NHibernate Tools: Visual NHibernate

    - by Ricardo Peres
    You probably know that I’m a big fan of Slyce Software’s Visual NHibernate. To me, it is the best tool for generating your entities and mappings from an existing database (it also allows you to go the other way, but I honestly have never used it that way). What I like most about it: Great support: folks at Slyce always listen to your suggestions, give you feedback in a timely manner, and I was even lucky enough to have some of my suggestions implemented! The templating engine, which is very powerful, and more user-friendly than, for example, MyGeneration’s; one of the included templates is Sharp Architecture; Advanced model validations: it even warns you about having lazy properties declared in non-lazy entities; Integration with NHibernate Validator and generation of validation rules automatically based on the database, or on user-defined model settings; The designer: they opted for not displaying all entities in a single screen, which I think was a good decision; has support for all inheritance strategies (table per class hierarchy, table per class, table per concrete class); Generation of FluentNHibernate mappings as well as hbm.xml. I could name others, but… why don’t you see for yourself? There is a demo version available for downloading. By the way, I am in no way related to Slyce, I just happen to like their software!

  • Why won't Mail sync To Do/Tasks with Exchange?

    - by cebjyre
    I'm using Apple Mail (Snow Leopard, everything is fully up-to-date), and am happily using an Exchange 2007 server for email needs, but I can't get it to synchronise the To Do notes from Mail with the Tasks from Exchange. I've tried creating a task in each and neither of them went to the other side. Bizarrely I have a single task from before I actually upgraded to Snow Leopard that did get into Mail from Exchange. Right-clicking on the Inbox and hitting 'Get Account Info' in Mail reports the correct number of entries in the 'To Do' folder for 'Messages on Server'.

  • HP Smart Array; Is it possible to convert Raid1 to Raid0 by dropping a failed drive?

    - by Erik Heppler
    I have a server that was running two 60GB drives as a logical RAID1. At some point the second drive was physically removed and the logical drive has been in "Interim Recovery Mode" for several months now. There's no need for the redundancy of RAID1 on this machine, and I have no intention of replacing the missing drive. If possible I would like to convert the current RAID1 to a single-drive RAID0 by simply dropping the failed drive from the current configuration. I'm only interested in doing this if it can be done in-place. Otherwise I'm perfectly content to leave it in "Interim Recovery Mode" indefinitely.

  • Cutting and pasting in MS Word: hourglass pops and it takes longer than expected

    - by Rax Olgud
    I work with MS Word 2007. Today I created a new document, and for some reason cutting and pasting text (using Ctrl-X and Ctrl-V) takes longer than expected. To clarify, here's the process: I select a single word in the document I click Ctrl-X The hourglass shows up for 1-2 seconds The word is cut The same happens for pasting (i.e. 1-2 seconds of hourglass). This document is ~5 pages long, with nothing fancy. I have plenty of available RAM and my CPU usage is around 1-2%, there's not peak during the cut/paste. Any thoughts on what can cause this and what I can do against it?

  • Mail Merge in Microsoft Word with images from Sharepoint

    - by Ian Turner
    Is there any way of doing a Mail Merge in Microsoft Word 2007 taking data, including images from a Sharepoint site? It's a bit crude, but I've managed to merge text by taking the data off the sharepoint site as an Excel sheet and then merging that. My problem is what to do with the images. I can set references to the images up in the Sharepoint site, however all I can find is a way of Mail Merging when images are in the same folder as the document you are trying to Merge and I can't find a sensible automated way to pulls these images together into one single folder.

  • Personal Software Process (PSP1)

    - by gentoo_drummer
    I'm trying to figure out an exercise but it doesn't really makes to much sense.. I'm not asking someone to provide the solution. just to try and analyse what needs to be done in order to solve this. I'm trying to understand which PSP 1.0 1.1 process I should use. PROBE? Or something else? I would greatly appreciate some help on this one from someone that has experience with the Personal Software Process Methodology.. Here is the question. For the reference case (“code1.c”), the following s/w metrics are provided: man-hours spent in implementation phase (per-module): 2,7 mh/file man-hours spent in testing phase (per-module): 4,3 mh/file estimated number of bugs remaining (per-module): 0,3 errors/function, 4 errors/module (remaining) Based on the corresponding values provided for the reference case, each of the following tasks focus on some s/w metrics to be estimated for the test case (“code2.c”): [25 marks] (estimated) man-hours required in implementation phase (per-module) [8 marks] (estimated) man-hours required in testing phase (per-module) [8 marks] (estimated) number of bugs remaining at the end of testing phase (per-module) [9 marks] Tasks 4 through 6 should use the data provided for the reference case within the context of Personal Software Process level-1 (PSP-1), using them as a single-point historic data log. Specifically, the same s/w metrics are to be estimated for the test case (“code2.c”), using PSP as the basic estimation model. In order to perform the above listed tasks, students are advised to consider all phases of the PSP software development process, especially at levels PSP0 and PSP1. Both cases are to be treated as separate case-studies in the context of classic s/w development.

  • Apache DVB http video Streaming bandwidth or priority problem

    - by igino manfre'
    I'm streaming few precompressed DVB videos from cloud. The streams are generated from VLC on "impossible" ports (such as 64085, 64086 etc) reverse proxed by Apache on port 80 and 8080. All the generated streams are listed in "http://95.110.164.61/indexv.html". From an ADSL connection with enough downlink bandwidth, recalling the stream generated by VLC (such as "http://95.110.164.61:64087/mpg2_6.4") it flows fluently. Recalling the same stream proxed by Apache ("http://95.110.164.61/mpg2_6.4") the stream stops and goes. The only situation in which the Apache proxed streams flow regularly is from a site connected through 64 Mbps warranted bandwith with RTT to the server less than 10 mseconds. Please note that streams below 2 Mbps are fluently proxed. The system is a single core xeon with windows 2008 R2 on 4 GB of RAM with 1 Gbps of network bandwidth. The drain of computational and bandwidth resources is negligeable, the RAM usage always lower than 50%. On the system I run many VLC streamers. Any of them drains a variable amount of RAM (from about 25 to 70 MB). On the contrary the couple of httpd.exe processes drain no more than 7 MB. Using Wireshark (on the server) I see that VLC directy send to the client much more packets than Apache, and the stream is framgmented on many frames. I'm not a programmer, a newby of Apache. Can anyone please address me to a specific portion of the Apache's huge documentation? Thank you. igino

  • Intel Rapid Storage Technology service always crashes

    - by Massimo
    I'm running Windows 7 x64 on a system based on an Asus Z87-Deluxe motherboard; the storage is configured for RAID mode; there is a single SSD drive for the O.S. and two 4-TB disks in a RAID 1 setup for the data. I've installed the latest version of Intel's Rapid Storage Technology drivers, 12.8.0.1016. The program complains about its service not being running, and the service is actually stopped; if I try to start it, it crashes. I've already tried reinstalling the package, but nothing changed. All the disks work correctly, but the RST program is unusable. How can I fix this?

  • Building a Redundant / Distributed Application

    - by MattW
    This is more of a "point me in the right direction" question. My team of three and I have built a hosted web app that queues and routes customer chat requests to available customer service agents (It does other things as well, but this is enough background to illustrate the issue). The basic dev architecture today is: a single page ajax web UI (ASP.NET MVC) with floating chat windows (think Gmail) a backend Windows service to queue and route the chat requests this service also logs the chats, calculates service levels, etc a Comet server product that routes data between the web frontend and the backend Windows service this also helps us detect which Agents are still connected (online) And our hardware architecture today is: 2 servers to host the web UI portion of the application a load balancer to route requests to the 2 different web app servers a third server to host the SQL Server DB and the backend Windows service responsible for queuing / delivering chats So as it stands today, one of the web app servers could go down and we would be ok. However, if something would happen to the SQL Server / Windows Service server we would be boned. My question - how can I make this backend Windows service logic be able to be spread across multiple machines (distributed)? The Windows service is written to accept requests from the Comet server, check for available Agents, and route the chat to those agents. How can I make this more distributed? How can I make it so that I can distribute the work of the backend Windows service can be spread across multiple machines for redundancy and uptime purposes? Will I need to re-write it with distributed computing in mind? I should also note that I am hosting all of this on Rackspace Cloud instances - so maybe it is something I should be less concerned about? Thanks in advance for any help!

  • Simplest way to render image over top of another with another image used as mask in OpenGL?

    - by Adam Naylor
    The effect I'm looking for is to have a single large background image that is always visible (at full alpha) and then show a second image (what I call a light map or specular map) that is partially shown over the top based on a third image (which is effectively a mask). The effect is similar to this effect except instead of simply darkening or lightening the background image using the third image it needs to mask the second without effecting the first at all. The third image is the only one that moves therefore hard baking the third images alpha into the second image isn't an option. If my explanation isn't clear I'll provide visual examples when I have more time. I'd prefer not to go down a shader route as I haven't taught myself this area yet so unless I have too I'd rather try to achieve this with simple alpha blending. Happy to use a shader approach. Cheers. Additional These third images are obviously light sources being cast onto the first image showing the specular information from the second image to simulate the light 'shining' off the objects in the first image. The solution I implement will need to allow two light sources to potentially overlap so my current thoughts are that the alpha values of the two images will need to be combined (Added?) to produce a final image which masks the second image? Don't worry about things like coloured lights. For this technique the lights are all considered white.

  • ZFS Basics

    - by user12614620
    Stage 1 basics: creating a pool # zpool create $NAME $REDUNDANCY $DISK1_0..N [$REDUNDANCY $DISK2_0..N]... $NAME = name of the pool you're creating. This will also be the name of the first filesystem and, by default, be placed at the mountpoint "/$NAME" $REDUNDANCY = either mirror or raidzN, and N can be 1, 2, or 3. If you leave N off, then it defaults to 1. $DISK1_0..N = the disks assigned to the pool. Example 1: zpool create tank mirror c4t1d0 c4t2d0 name of pool: tank redundancy: mirroring disks being mirrored: c4t1d0 and c4t2d0 Capacity: size of a single disk Example 2: zpool create tank raidz c4t1d0 c4t2d0 c4t3d0 c4t4d0 c4t5d0 Here the redundancy is raidz, and there are five disks, in a 4+1 (4 data, 1 parity) config. This means that the capacity is 4 times the disk size. If the command used "raidz2" instead, then the config would be 3+2. Likewise, "raidz3" would be a 2+3 config. Example 3: zpool create tank mirror c4t1d0 c4t2d0 mirror c4t3d0 c4t4d0 This is the same as the first mirror example, except there are two mirrors now. ZFS will stripe data across both mirrors, which means that writing data will go a bit faster. Note: you cannot create a mirror of two raidzs. You can create a raidz of mirrors, but to do that requires trickery.

  • Blink-Data vs Instinct?

    - by Samantha.Y. Ma
    In his landmark bestseller Blink, well-known author and journalist Malcolm Gladwell explores how human beings everyday make seemingly instantaneous choices --in the blink of an eye--and how we “think without thinking.”  These situations actually aren’t as simple as they seem, he postulates; and throughout the book, Gladwell seeks answers to questions such as: 1.    What makes some people good at thinking on their feet and making quick spontaneous decisions?2.    Why do some people follow their instincts and win, while others consistently seem to stumble into error?3.    Why are some of the best decisions often those that are difficult to explain to others?In Blink, Gladwell introduces us to the psychologist who has learned to predict whether a marriage will last, based on a few minutes of observing a couple; the tennis coach who knows when a player will double-fault before the racket even makes contact with the ball; the antiquities experts who recognize a fake at a glance. Ultimately, Blink reveals that great decision makers aren't those who spend the most time deliberating or analyzing information, but those who focus on key factors among an overwhelming number of variables-- i.e., those who have perfected the art of "thin-slicing.” In Data vs. Instinct: Perfecting Global Sales Performance, a new report sponsored by Oracle, the Economist Intelligence Unit (EIU) explores the roles data and instinct play in decision-making by sales managers and discusses how sales executives can increase sales performance through more effective  territory planning and incentive/compensation strategies.If you are a sales executive, ask yourself this:  “Do you rely on knowledge (data) when you plan out your sales strategy?  If you rely on data, how do you ensure that your data sources are reliable, up-to-date, and complete?  With the emergence of social media and the proliferation of both structured and unstructured data, how do you know that you are applying your information/data correctly and in-context?  Three key findings in the report are:•    Six out of ten executives say they rely more on data than instinct to drive decisions. •    Nearly one half (48 percent) of incentive compensation plans do not achieve the desired results. •    Senior sales executives rely more on current and historical data than on forecast data. Strikingly similar to what Gladwell concludes in Blink, the report’s authors succinctly sum up their findings: "The best outcome is a combination of timely information, insightful predictions, and support data."Applying this insight is crucial to creating a sound sales plan that drives alignment and results.  In the area of sales performance management, “territory programs and incentive compensation continue to present particularly complex challenges in an increasingly globalized market," say the report’s authors. "It behooves companies to get a better handle on translating that data into actionable and effective plans." To help solve this challenge, CRM Oracle Fusion integrates forecasting, quotas, compensation, and territories into a single system.   For example, Oracle Fusion CRM provides a natural integration between territories, which define the sales targets (e.g., collection of accounts) for the sales force, and quotas, which quantify the sales targets. In fact, territory hierarchy is a core analytic dimension to slice and dice sales results, using sales analytics and alerts to help you identify where problems are occurring. This makes territoriesStart tapping into both data and instinct effectively today with Oracle Fusion CRM.   Here is a short video to provide you with a snapshot of how it can help you optimize your sales performance.
