• How important is to sacriface your free time for accomplishing goals? [closed]

  - by Darf Zon

  I was reading a book about XP programming and about agile teams. While I was reading, I saw this scenario. I've never worked with a development team (just in school). So I would like what do you opine on this situation: Your boss has asked you to deliver software in a time that can only be possible to meet the project team asking if you want to work overtime without pay. All team members have young children. Discuss whether it should accept this request from your boss or should persuade the team to give their time to the organization rather than their families. What could be significant factors in the decision? As a programmer, you are offered an upgrade as project manager, but his feeling is that you can have a more effective contribution in a technical role in one administrative. Write when you should accept that promotion. Somethimes, I sacrifice my free time for accomplishing hits at work, so it's very important to me to know your opinion base of your experience.

• A Patent for Workload Management Based on Service Level Objectives

  - by jsavit

  I'm very pleased to announce that after a tiny :-) wait of about 5 years, my patent application for a workload manager was finally approved. Background Many operating systems have a resource manager which lets you control machine resources. For example, Solaris provides controls for CPU with several options: shares for proportional CPU allocation. If you have twice as many shares as me, and we are competing for CPU, you'll get about twice as many CPU cycles), dedicated CPU allocation in which a number of CPUs are exclusively dedicated to an application's use. You can say that a zone or project "owns" 8 CPUs on a 32 CPU machine, for example. And, capped CPU in which you specify the upper bound, or cap, of how much CPU an application gets. For example, you can throttle an application to 0.125 of a CPU. (This isn't meant to be an exhaustive list of Solaris RM controls.) Workload management Useful as that is (and tragic that some other operating systems have little resource management and isolation, and frighten people into running only 1 app per OS instance - and wastefully size every server for the peak workload it might experience) that's not really workload management. With resource management one controls the resources, and hope that's enough to meet application service objectives. In fact, we hold resource distribution constant, see if that was good enough, and adjust resource distribution if that didn't meet service level objectives. Here's an example of what happens today: Let's try 30% dedicated CPU. Not enough? Let's try 80% Oh, that's too much, and we're achieving much better response time than the objective, but other workloads are starving. Let's back that off and try again. It's not the process I object to - it's that we to often do this manually. Worse, we sometimes identify and adjust the wrong resource and fiddle with that to no useful result. Back in my days as a customer managing large systems, one of my users would call me up to beg for a "CPU boost": Me: "it won't make any difference - there's plenty of spare CPU to be had, and your application is completely I/O bound." User: "Please do it anyway." Me: "oh, all right, but it won't do you any good." (I did, because he was a friend, but it didn't help.) Prior art There are some operating environments that take a stab about workload management (rather than resource management) but I find them lacking. I know of one that uses synthetic "service units" composed of the sum of CPU, I/O and memory allocations multiplied by weighting factors. A workload is set to make a target rate of service units consumed per second. But this seems to be missing a key point: what is the relationship between artificial 'service units' and actually meeting a throughput or response time objective? What if I get plenty of one of the components (so am getting enough service units), but not enough of the resource whose needed to remove the bottleneck? Actual workload management That's not really the answer either. What is needed is to specify a workload's service levels in terms of externally visible metrics that are meaningful to a business, such as response times or transactions per second, and have the workload manager figure out which resources are not being adequately provided, and then adjust it as needed. If an application is not meeting its service level objectives and the reason is that it's not getting enough CPU cycles, adjust its CPU resource accordingly. If the reason is that the application isn't getting enough RAM to keep its working set in memory, then adjust its RAM assignment appropriately so it stops swapping. Simple idea, but that's a task we keep dumping on system administrators. In other words - don't hold the number of CPU shares constant and watch the achievement of service level vary. Instead, hold the service level constant, and dynamically adjust the number of CPU shares (or amount of other resources like RAM or I/O bandwidth) in order to meet the objective. Instrumenting non-instrumented applications There's one little problem here: how do I measure application performance in a way relating to a service level. I don't want to do it based on internal resources like number of CPU seconds it received per minute - We need to make resource decisions based on externally visible and meaningful measures of performance, not synthetic items or internal resource counters. If I have a way of marking the beginning and end of a transaction, I can then measure whether or not the application is meeting an objective based on it. If I can observe the delay factors for an application, I can see which resource shortages are slowing an application enough to keep it from meeting its objectives. I can then adjust resource allocations to relieve those shortages. Fortunately, Solaris provides facilities for both marking application progress and determining what factors cause application latency. The Solaris DTrace facility let's me introspect on application behavior: in particular I can see events like "receive a web hit" and "respond to that web hit" so I can get transaction rate and response time. DTrace (and tools like prstat) let me see where latency is being added to an application, so I know which resource to adjust. Summary After a delay of a mere few years, I am the proud creator of a patent (advice to anyone interested in going through the process: don't hold your breath!). The fundamental idea is fairly simple: instead of holding resource constant and suffering variable levels of success meeting service level objectives, properly characterise the service level objective in meaningful terms, instrument the application to see if it's meeting the objective, and then have a workload manager change resource allocations to remove delays preventing service level attainment. I've done it by hand for a long time - I think that's what a computer should do for me.

• Terrible ping time with TP-Link wireless router

This happens from time to time. I'd restart the router, and then it'll have a 1-2 ms ping for a while, and then back to terrible ping. Is it just a poor quality router? Suggestions? Thank you

• My company's management wants to deduct from the salary of under performing employees. How can I convince them not to?

  - by Sparky

  My company's management wants to deduct from the salary of under performing employees. I'm a member of the Core Strategy committee and they want my opinion also. I believe that the throughput from an employee depends on a lot of things such as the particular work assigned to them, other members of his/her team, other reasons etc. Such penalizations will be demoralizing to the people. How can I convince my management not to do so?

• Is there any way to properly display negative time spans in Excel?

  - by Pepor

  Is there any way to make Excel show a negative time span? If I subtract two time values (say, when subtracting the actual amount of time spent on something from the amount of time planned for it) and the result is negative, Excel just fills the result cell with hashes to notify me that the result cannot be displayed as a time value. Even OpenOffice.org Calc and Google Spreadsheets can display negative time values. Is there a way to work around that issue by using conditional formatting? I really don't want to create some workaround by calculating the hours and minutes myself or anything like that.

• What groupware/project-management apps (preferably self-hosted webapp) do you recommend for a small dev shop?

  - by HedgeMage

  I run a small Drupal consulting shop and we've been trying different groupware solutions for what seems like ages, yet nothing we've found seems to be a good fit. We don't need CRM-overkill such as SugarCRM offers -- it's just too much for our small size. We do need git integration (at a minimum, an easy way to associate commits with issues) Time tracking on configurable or 15m increments per-project issue tracking billing (incl. recurring billing for support contracts, etc) some sort of per-project notes/wiki for things like login credentials, client contact info, etc. Contact logging (Client foo called at 2:20pm and asked to add bar to the spec, signed addendum with pricing due to client NLT CoB today, to be returned by CoB tomorrow) Open source solutions are greatly preferred to closed ones Most of all, it should be very efficient to use. Several solutions just fell out of use here because they required too many clicks for simple, frequent tasks like logging time spent on an issue or noting a call from a client. It shouldn't take 20 minutes to make a note. Edit: I almost forgot to mention: we're a mixed Linux/Mac shop with no Windows users.

• What's the best project management software for internal dev. 5 man shop

  - by P.Brian.Mackey

  I work for a large corporation, but we do small intranet web application development. Our project management tracking sucks. Its custom software built by a jr. intern. For what its worth, our development style is akin to agile, but there's nothing set in stone...very customer oriented approach. I need project tracking that meets the criteria: Intranet, internal products. Mostly maintenance, some new development. 5 developers 12 products 1 hands-off manager. He really just wants to know estimated man hours, due date for dev, QA and release. Along with a short description of the project. Free or super cheap. Bonus Simple pretty UI. Think pretty charts. Hope I covered everything. Please ask for any clarification. If you read dreaming in code, the company uses some project tracking software that sounds pretty sweet. Note, we do have Team Foundation Server. I already tried pushing its use as PM tracking, but its too complicated. I can't get people to sit and train. So this software has to be easy.

• Calculate travel time on road map with semaphores

  - by Ivansek

  I have a road map with intersections. At intersections there are semaphores. For each semaphore I generate a red light time and green light time which are represented with syntax [R:T1, G:T2], for example: 119 185 250 A ------- B: [R:6, G:4] ------ C: [R:5, G:5] ------ D I want to calculate a car travel time from A - D. Now I do this with this pseudo code: function get_travel_time(semaphores_configuration) { time = 0; for( i=1; i<path.length;i++) { prev_node = path[i-1]; next_node = path[i]); cost = cost_between(prev_node, next_node) time += (cost/movement_speed) // movement_speed = 50px per second light_times = get_light_times(path[i], semaphore_configurations) lights_cycle = get_lights_cycle(light_times) // Eg: [R,R,R,G,G,G,G], where [R:3, G:4] lights_sum = light_times.green_time+light_times.red_light; // Lights cycle time light = lights_cycle[cost%lights_sum]; if( light == "R" ) { time += light_times.red_light; } } return time; } So for distance 119 between A and B travel time is, 119/50 = 2.38s ( exactly mesaured time is between 2.5s and 2.6s), then we add time if we came at a red light when at B. If we came at a red light is calculated with lines: lights_cycle = get_lights_cycle(light_times) // Eg: [R,R,R,G,G,G,G], where [R:3, G:4] lights_sum = light_times.green_time+light_times.red_light light = lights_cycle[cost%lights_sum]; if( light == "R" ) { time += light_times.red_light; } This pseudo code doesn't calculate exactly the same times as they are mesaured, but the calculations are very close to them. Any idea how I would calculate this?

• What are the memory-management capabilities of MySQL + JDBC (in light of autonomic computing)?

  - by Adel

  I'm interested in implementing some kind of autonomic-computing functionality using MySQL. By autonomic-computing I mean roughly some failsafe abilities, whereby the application appears to be at least slightly "intelligent" For reference, the main parts of autonomic computing we'd like are the "self-configuring" and "self-healing" features (the other two - "self-optimizing" and "self-protecting", are too abstract/futuristic for us, at this time). Sofor example, if we have a sample Java application that utilizes a MySQL database, we might want to automatically restart the MySQL database if we take up too much memory. Or maybe we want to have the ability to dynamiccally adjust the database memory as needed. So for example, when we start the application the database begins with a 56 Megabyte buffer; but then as we insert so many rows we want to have it automatically jump up to 512 MB, then to 1024, until a max of 4096 MB. Does all of the above suggest that MySQL is too "weak" for the task? Do you suggest using Oracle database? My professor believes that by using Java we can basically make up for any memory-management deficiencies that MySQL has in relation to Oracle DB. I'm new to MySQL , but have experience with Oracle. If all of the above sounds wishy-washy, it is because I'm still fleshing it out. thanks

• I need to calculate the date / time difference between one date time column

  - by Stringz

  Details. I have the notes table having the following columns. ID - INT(3) Date - DateTime Note - VARCHAR(100) Tile - Varchar(100) UserName - Varchar(100) Now this table will be having NOTES along with the Titles entered by UserName on the specified date / time. I need to calculate the DateTimeDifference between the TWO ROWS in the SAME COLUMN For example the above table has this peice of information in the table. 64, '2010-03-26 18:16:13', 'Action History', 'sending to Level 2.', 'Salman Khwaja' 65, '2010-03-26 18:19:48', 'Assigned By', 'This is note one for the assignment of RF.', 'Salman Khwaja' 66, '2010-03-27 19:19:48', 'Assigned By', 'This is note one for the assignment of CRF.', 'Salman Khwaja' Now I need to have the following resultset in query reports using MYSQL. TASK - TIME Taken ACTION History - 2010-03-26 18:16:13 Assigned By - 00:03:35 Assigned By - 25:00:00 More smarter approach would be TASK - TIME Taken ACTION History - 2010-03-26 18:16:13 Assigned By - 3 minutes 35 seconds Assigned By - 1 day, 1 hour. I would appreciate if one could give me the PLAIN QUERY along with PHP code to embed it too.

• Custom date time picker for Windows Forms that is locked to GMT time

  - by m3ntat

  Using Visual Studio 2008, c#, .net 2.0. I have a Windows Forms client application that contains a scheduling UI section, currently this is housed only in the London office with the standard datetime picker control, the selected time is saved in a UK database (GMT) and a London based server aapplication processes the schedules. There is a requirement to roll the client out to various global locations, Hong Kong, New York etc and allow them to setup schedules that run according to GMT time on the London server. I'll have a label on screen saying "note schedules are GMT" what I need is a good way to present a datetime picker that always shows and is in sync with the database server's GMT time regardless of where the client app is running globally. Suggestions on how to acheive this? thanks.

The steps to calculate the anomalies are following: Monthly premature departures from the long-term (1991-2007) average are obtained. Then standardized by dividing by the standard deviation of monthly temperature. The standardized monthly anomalies are then weighted by multiplying by the fraction of the average temperature for the given month. These weighted anomalies are then summed over 3 month time period. Can you please help me?

• java time check API

  - by ring bearer

  I am sure this was done 1000 times in 1000 different places. The question is I want to know if there is a better/standard/faster way to check if current "time" is between two time values given in hh:mm:ss format. For example, my big business logic should not run between 18:00:00 and 18:30:00. So here is what I had in mind: public static boolean isCurrentTimeBetween(String starthhmmss, String endhhmmss) throws ParseException{ DateFormat hhmmssFormat = new SimpleDateFormat("yyyyMMddhh:mm:ss"); Date now = new Date(); String yyyMMdd = hhmmssFormat.format(now).substring(0, 8); return(hhmmssFormat.parse(yyyMMdd+starthhmmss).before(now) && hhmmssFormat.parse(yyyMMdd+endhhmmss).after(now)); } Example test case: String doNotRunBetween="18:00:00,18:30:00";//read from props file String[] hhmmss = downTime.split(","); if(isCurrentTimeBetween(hhmmss[0], hhmmss[1])){ System.out.println("NOT OK TO RUN"); }else{ System.out.println("OK TO RUN"); } What I am looking for is code that is better in performance in looks in correctness What I am not looking for third-party libraries Exception handling debate variable naming conventions method modifier issues

• average case running time of linear search algorithm

  - by Brahadeesh

  Hi all. I am trying to derive the average case running time for deterministic linear search algorithm. The algorithm searches an element x in an unsorted array A in the order A[1], A[2], A[3]...A[n]. It stops when it finds the element x or proceeds until it reaches the end of the array. I searched on wikipedia and the answer given was (n+1)/(k+1) where k is the number of times x is present in the array. I approached in another way and am getting a different answer. Can anyone please give me the correct proof and also let me know whats wrong with my method? E(T)= 1*P(1) + 2*P(2) + 3*P(3) ....+ n*P(n) where P(i) is the probability that the algorithm runs for 'i' time (i.e. compares 'i' elements). P(i)= (n-i)C(k-1) * (n-k)! / n! Here, (n-i)C(k-1) is (n-i) Choose (k-1). As the algorithm has reached the ith step, the rest of k-1 x's must be in the last n-i elements. Hence (n-i)C(k-i). (n-k)! is the total number of ways of arranging the rest non x numbers, and n! is the total number of ways of arranging the n elements in the array. I am not getting (n+1)/(k+1) on simplifying.

• Time complexity of a certain program

  - by HokageSama

  In a discussion with my friend i am not able to predict correct and tight time complexity of a program. Program is as below. /* This Function reads input array "input" and update array "output" in such a way that B[i] = index value of nearest greater value from A[i], A[i+1] ... A[n], for all i belongs to [1, n] Time Complexity: ?? **/ void createNearestRightSidedLargestArr(int* input, int size, int* output){ if(!input || size < 1) return; //last element of output will always be zero, since no element is present on its right. output[size-1] = -1; int curr = size - 2; int trav; while(curr >= 0){ if(input[curr] < input[curr + 1]){ output[curr] = curr + 1; curr--; continue; } trav = curr + 1; while( input[ output [trav] ] < input[curr] && output [trav] != -1) trav = output[trav]; output[curr--] = output[trav]; } } I said time complexity is O(n^2) but my friend insists that this is not correct. What is the actual time complexity?

• How to display locale sensitive time format without seconds in python

  I can output a locale sensitive time format using strftime('%X'), but this always includes seconds. How might I display this time format without seconds? >>> import locale >>> import datetime >>> locale.setlocale(locale.LC_ALL, 'en_IE.utf-8') 'en_IE.utf-8' >>> print datetime.datetime.now().strftime('%X') 12:22:43 >>> locale.setlocale(locale.LC_ALL, 'zh_TW.utf-8') 'zh_TW.utf-8' >>> print datetime.datetime.now().strftime('%X') 12?22?58? The only way I can think of doing this is attempting to parse the output of locale.nl_langinfo(locale.T_FMT) and strip out the seconds bit, but that brings it's own trickery. >>> print locale.nl_langinfo(locale.T_FMT) %H?%M?%S? >>> locale.setlocale(locale.LC_ALL, 'en_IE.utf-8') 'en_IE.utf-8' >>> print locale.nl_langinfo(locale.T_FMT) %T

• Fetching real time data from excel

  - by Umesh Sharma

  I am seriouly looking for your valuable help first time here. If possible, plese help me. I am developing a VB.NET app in which i read "real time data" from a excel sheet using "Microsoft.Office.Interop.Excel" i.e. excel automation. All cells in excel sheet are fetching stock data from some LOCAL DDE Server like "=XYZ|Bid!GOLD", "=XYZ|Bid!SILVER", "=XYZ|Ask!SILVER" and so on... Some cells also having fixed values like "Symbol", "Bid Rate", "32.90" etc. Values of DDE mapped cells (i.e. =XYZ|xxxx!yyy) are continuously changing. THE PROBLEM is here..."FIXED values" from excel cells are coming quite ok to my app but all DDE mapped cells values are coming "-2146826246" (When datasource local dde server ON) or "-2146826265" (OFF). Although, if i use C#.NET, it's all ok but not with Vb.NET. I want to display range of excel (A1 to J50) into VB.NET ListView which are changing in every 200ms (5 times in every 1 second) ================ Important ====================================================== Is it possible to BIND "listview items/columns values" with "excel cells" or some local memory variables ?? Currently, i am reading excel "cell by cell" and trying to put values in .NET listview but CPU USES are very high as well as it's toooo slow process. If yes, then how please ? I am a VFP developer but new to .NET It's very easy in VFP then why not in .NET ?? Please guide me, if someone has the solution...

• linux bash script: set date/time variable to auto-update (for inclusion in file names)

  - by user1859492

  Essentially, I have a standard format for file naming conventions. It breaks down to this: target_dateUTC_timeUTC_tool So, for instance, if I run tcpdump on a target of 'foo', then the file would be foo_dateUTC_timeUTC_tcpdump. Simple enough, but a pain for everyone to constantly (and consistently) enter... so I've tried to create a bash script which sets system variables like so: FILENAME=$TARGET\_$UTCTIME\_$TOOL Then, I can just call the variable at runtime, like so: tcpdump -w $FILENAME.lpc All of this works like a champ. I've got a menu-driven .sh which gives the user the options of viewing the current variables as well as setting them... file generation is a breeze. Unfortunately, by setting the date/time variable, it is locked to the value at the time of creation (naturally). I set the variable like so: UTCTIME=$(/bin/date --utc +"%Y%m%d_%H%M%Z") What I really need is either a way to create a variable which updates at runtime, or (more likely) another way to skin this cat. While scouring for solutions, I came across a similar issues... like this. But, to be honest, I'm stumped on how to marry the two approaches and create a simple, distributable solution. I can post the entire .sh if anyone cares to review (about 120 lines)

Today, we’re going to focus on Social Relationship Management at Oracle OpenWorld.?Social networking is touching all businesses today.  Customers are speaking about your brand right now on social media sites. Your employees are speaking to one another on social media sites. In an Oracle survey, 40% of consumers factor in Facebook recommendations when making purchasing decisions. Despite the rise of social networking, 70% of marketers report having little understanding of social media conversations happening around their brand. Oracle has invested in technologies that will help companies leverage social media technologies for their enterprise. Our suite of social products is collectively known as Social Relationship Management. Customers are using Social Relationship Management to get analytics to social media conversations around their brand, manage multiple social media channels while keeping their brand consistent, optimize internal workflows and processes, and create better customer relationships and experiences. In this example, using Social Relationship Management, a high-end national grocery chain is able to see that “Coconut Water” is trending in San Francisco. They are now able to send a $2-off coconut water coupon to shoppers who have checked into their San Francisco locations. This promotion further drives sales of coconut water in San Francisco. In another example, using Social Relationship Management, a technology company creates multiple Facebook pages and runs campaigns on them. These social campaigns are now integrated and tracked as another marketing channel in Oracle Fusion CRM. The technology company can now track and respond to a particular customer as he moves across multiple channels – without having to restart the conversation each time the customer contacts the company. Furthermore, the technology company can see in one interface what marketing channels – including social – is performing best for each promotion. Besides being a Software-as-a-Service solution, social is also a Platform-as-a-Service solution. The benefit here is that customers can extend the functionality of our social applications to suit their particular needs or create their own social application from scratch. During the Social Developer track, developers are learning how to use Java and other industry-standard programming languages to plug in social functionality to enterprise applications. To see how Social Relationship Management can help your business build better relationships and experience with customers, visit us on the web at oracle.com/social. There are a lot more social-oriented sessions left at OpenWorld. To view a schedule of the upcoming social-oriented sessions, go here.

• ISACA Webcast follow up: Managing High Risk Access and Compliance with a Platform Approach to Privileged Account Management

  - by Darin Pendergraft

  Last week we presented how Oracle Privileged Account Manager (OPAM) could be used to manage high risk, privileged accounts.  If you missed the webcast, here is a link to the replay: ISACA replay archive (NOTE: you will need to use Internet Explorer to view the archive) For those of you that did join us on the call, you will know that I only had a little bit of time for Q&A, and was only able to answer a few of the questions that came in.  So I wanted to devote this blog to answering the outstanding questions.  Here they are. 1. Can OPAM track admin or DBA activity details during a password check-out session? Oracle Audit Vault is monitoring these activities which can be correlated to check-out events. 2. How would OPAM handle simultaneous requests? OPAM can be configured to allow for shared passwords.  By default sharing is turned off. 3. How long are the passwords valid?  Are the admins required to manually check them in? Password expiration can be configured and set in the password policy according to your corporate standards.  You can specify if you want forced check-in or not. 4. Can 2-factor authentication be used with OPAM? Yes - 2-factor integration with OPAM is provided by integration with Oracle Access Manager, and Oracle Adaptive Access Manager. 5. How do you control access to OPAM to ensure that OPAM admins don't override the functionality to access privileged accounts? OPAM provides separation of duties by using Admin Roles to manage access to targets and privileged accounts and to control which operations admins can perform. 6. How and where are the passwords stored in OPAM? OPAM uses Oracle Platform Security Services (OPSS) Credential Store Framework (CSF) to securely store passwords.  This is the same system used by Oracle Applications. 7. Does OPAM support hierarchical/level based privileges?  Is the log maintained for independent review/audit? Yes. OPAM uses the Fusion Middleware (FMW) Audit Framework to store all OPAM related events in a dedicated audit database.  8. Does OPAM support emergency access in the case where approvers are not available until later? Yes.  OPAM can be configured to release a password under a "break-glass" emergency scenario. 9. Does OPAM work with AIX? Yes supported UNIX version are listed in the "certified component section" of the UNIX connector guide at:http://docs.oracle.com/cd/E22999_01/doc.111/e17694/intro.htm#autoId0 10. Does OPAM integrate with Sun Identity Manager? Yes.  OPAM can be integrated with SIM using the REST  APIs.  OPAM has direct integration with Oracle Identity Manager 11gR2. 11. Is OPAM available today and what does it cost? Yes.  OPAM is available now.  Ask your Oracle Account Manager for pricing. 12. Can OPAM be used in SAP environments? Yes, supported SAP version are listed in the "certified component section" of the SAP  connector guide here: http://docs.oracle.com/cd/E22999_01/doc.111/e25327/intro.htm#autoId0 13. How would this product integrate, if at all, with access to a particular field in the DB that need additional security such as SSN's? OPAM can work with DB Vault and DB Firewall to provide the fine grained access control for databases. 14. Is VM supported? As a deployment platform Oracle VM is supported. For further details about supported Virtualization Technologies see Oracle Fusion Middleware Supported System configurations here: http://www.oracle.com/technetwork/middleware/ias/downloads/fusion-certification-100350.html 15. Where did this (OPAM) technology come from? OPAM was built by Oracle Engineering. 16. Are all Linux flavors supported?  How about BSD? BSD is not supported. For supported UNIX version see the "certified component section" of the UNIX connector guide http://docs.oracle.com/cd/E22999_01/doc.111/e17694/intro.htm#autoId0 17. What happens if users don't check passwords in at the end of a work task? In OPAM a time frame can be defined how long a password can be checked out. The security admin can force a check-in at any given time. 18. is MySQL supported? Yes, supported DB version are listed in the "certified component section" of the DB connector guide here: http://docs.oracle.com/cd/E22999_01/doc.111/e28315/intro.htm#BABGJJHA 19. What happens when OPAM crashes and you need to use the password? OPAM can be configured for high availability, but if required, OPAM data can be backed up/recovered.  See the OPAM admin guide. 20. Is OPAM Standalone product or does it leverage other components from IDM? OPAM can be run stand-alone, but will also leverage other IDM components

It is engaged in the exploration, acquisition, integration, and efficient development of oil and gas fields outside the Russian Federation to promote transforming LUKOIL into a transnational energy company. In 2010, the company signed a 20-year development project for the giant, West Qurna 2 oil field in Iraq. Executing 10,000 to 15,000 project activities simultaneously on 14 major construction and drilling projects in Iraq for the West Qurna-2 project meant the company needed a clear picture, in real time, of dependencies between its capital construction, geologic exploration and sinking projects—required for its building infrastructure oil field development projects in Iraq. LUKOIL Overseas Holding deployed Oracle’s Primavera P6 Enterprise Project Portfolio Management to generate structured project management information and optimize planning, monitoring, and analysis of all engineering and commercial activities—such as tenders, and bulk procurement of materials and equipment—related to oil field development projects. A word from LUKOIL Overseas Holding Ltd. “Previously, we created project schedules on desktop computers and uploaded them to the project server to be merged into one big file for each project participant to access. This was not scalable, as we’ve grown and now run up to 15,000 activities in numerous projects and subprojects at any time. With Oracle’s Primavera P6 Enterprise Project Portfolio Management, we can now work concurrently on projects with many team members, enjoy absolute security, and issue new baselines for all projects and project participants once a week, with ease.” – Sergey Kotov, Head of IT and the Communication Office, LUKOIL Mid-East Ltd. Oracle Primavera Solutions: · Facilitated managing dependencies between projects by enabling the general scheduler to reschedule all projects and subprojects once a week, realigning 10,000 to 15,000 project activities that the company runs at any time · Replaced Microsoft Project and a paper-based system with a complete solution that provides structured project data · Enhanced data security by establishing project management security policies that enable only authorized project members to edit their project tasks, while enabling each project participant to view all project data that are relevant to that individual’s task · Enabled the company to monitor project progress in comparison to the projected plan, based on physical project assets to determine if each project is on track to conclude within its time and budget limitations To view the full list of solutions view here. “Oracle Gold Partner Parma Telecom was key to our successful Primavera deployment, implementing the software’s basic functionalities, such as project content, timeframes management, and cost management, in addition to performing its integration with our enterprise resource planning system and intranet portal within ten months and in accordance with budgets,” said Rafik Baynazarov, head of the master planning and control office, LUKOIL Mid-East Ltd. “ To read the full version of the customer success story, please view here.

• Trac vs. Redmine vs. JIRA vs. FogBugz for one-man shop?

  - by kizzx2

  Background I am a one-man freelancer looking for a project management software that can provide the following requirements. I have used Trac for about a year now. Tried Redmine and FogBugz on Demand for a couple of weeks. Never tried JIRA before. Basically, I'm looking for a piece of software that: Facilitates developer-client communication/collaboration Does time tracking Requirements Record time estimates/Time tracking Clients must be able to create/edit his own tickets/cases Clients must not see Developer created tickets/cases (internal) Affordable (price) with multiple clients Nice-to-haves Supports multiple projects in one installation Free eclipse integration (Mylyn) Easy time-tracking without using the Web UI (Trac's post commit hook or Redmine's commit message scanning) Clients can access the Wiki Export the data to standard formats My evaluation Trac can basically fulfill most of the above requirements, but with lots of customizations and plug-ins that it doesn't feel so clean. One downside is that the main trunk (0.11) has been around for a year or more and I still haven't seen much tendency of any upgrades coming up. Redmine has the cleanest Web UI. It's design philosophy seems to be the most elegant, with its innovative commit message scanning and stuff. However, the current version doesn't seem to be very mature and stable yet. It doesn't support internal (private) tickets and the time-tracking commit message patch doesn't support the trunk version. The good thing about it is that the main trunk still seems to be actively developed. FogBugz is actually a very well written piece of software. However the idea of paying $25/month for the client to be able to log-in to the system seems a little bit too far off for an individual developer. The free version supports letting clients create/view their own cases using email, which is a sub-optimal alternative to having a full-fledged list of the user's own cases. That also means clients can't read/write wiki pages. Its time-tracking approach is innovative and good though. However the fact that all the eclipse integration (Bugclipse, Foglyn) are commercial. Yet other investments before I can use my bug-tracker! If I revert back to the Web UI, it's not really a fast rendering Web service. Also, the in-built report functions are excellent (e.g. evidence based scheduling) JIRA is something I have zero experience with. Can someone with JIRA experience recommend why it might be a good fit for this particular situation? Question Can we share experience on this? Any specific plugins/customizations would that would best suit the requirements for this case?

• PostgreSQL to Data-Warehouse: Best approach for near-real-time ETL / extraction of data

  - by belvoir

  Background: I have a PostgreSQL (v8.3) database that is heavily optimized for OLTP. I need to extract data from it on a semi real-time basis (some-one is bound to ask what semi real-time means and the answer is as frequently as I reasonably can but I will be pragmatic, as a benchmark lets say we are hoping for every 15min) and feed it into a data-warehouse. How much data? At peak times we are talking approx 80-100k rows per min hitting the OLTP side, off-peak this will drop significantly to 15-20k. The most frequently updated rows are ~64 bytes each but there are various tables etc so the data is quite diverse and can range up to 4000 bytes per row. The OLTP is active 24x5.5. Best Solution? From what I can piece together the most practical solution is as follows: Create a TRIGGER to write all DML activity to a rotating CSV log file Perform whatever transformations are required Use the native DW data pump tool to efficiently pump the transformed CSV into the DW Why this approach? TRIGGERS allow selective tables to be targeted rather than being system wide + output is configurable (i.e. into a CSV) and are relatively easy to write and deploy. SLONY uses similar approach and overhead is acceptable CSV easy and fast to transform Easy to pump CSV into the DW Alternatives considered .... Using native logging (http://www.postgresql.org/docs/8.3/static/runtime-config-logging.html). Problem with this is it looked very verbose relative to what I needed and was a little trickier to parse and transform. However it could be faster as I presume there is less overhead compared to a TRIGGER. Certainly it would make the admin easier as it is system wide but again, I don't need some of the tables (some are used for persistent storage of JMS messages which I do not want to log) Querying the data directly via an ETL tool such as Talend and pumping it into the DW ... problem is the OLTP schema would need tweaked to support this and that has many negative side-effects Using a tweaked/hacked SLONY - SLONY does a good job of logging and migrating changes to a slave so the conceptual framework is there but the proposed solution just seems easier and cleaner Using the WAL Has anyone done this before? Want to share your thoughts?
