• FMw Diagnostic Framework : Automatic Capture of Diagnostic Data Upon First Failure!

  - by Daniel Mortimer

  Introduction There is nothing more frustrating than a problem that "cannot be reproduced". Logs, configuration files have been analysed but there just isn't enough information to establish the root cause. The issue maybe closed, but you are left with the feeling that the problem will raise its ugly head again in the future. Trouble is, to resolve such issues you need to capture diagnostic data at the exact time the incident occurs. Step forward Fusion Middleware Diagnostic Framework!  Diagnostic Framework monitors WebLogic Managed Servers and delivers "Automatic capture of diagnostic data upon first failure". To quote fromOracle Fusion Middleware Administrator's Guide 11g Release 1 (11.1.1)Chapter 13 Diagnosing Problems "When a critical error occurs ... the Diagnostic Framework automatically collects diagnostics, such as thread dumps, DMS metric dumps, and WebLogic Diagnostics Framework (WLDF) server image dumps ... The data is stored in a file-based repository and is accessible with command-line utilities." In other words the data collected upon first failure - especially the thread and image dumps - provides a snapshot of the system as or immediately after the problem occurs. The table below shows the type of WebLogic Server issues which fall into the scope of Diagnostic Framework How to Configure Diagnostic Framework? Depending on your Fusion Middleware product choice you may not need to do anything! Diagnostic Framework is automatically installed, configured and initiated for any WebLogic Domain which has the Oracle Java Required Files (JRF) template applied. This template is applied by default whenever you configure WebLogic Managed Servers for products such as Portal / Forms / Reports / Discoverer Identity Management ( OID , OAM , OIM etc) WebCenter SOA Check your WebLogic Domain directory structure. If you have an "adr" sub directory under DOMAIN_HOME/servers/<servername>/ then JRF template has been applied and Diagnostic Framework will be in play. Should the "adr" sub directory not exist, review the advice given in My Oracle Support article How to Apply FMW ( EM ) Control and JRF to a WebLogic Domain and Managed Servers [ID 947043.1] If you are working with a standalone WebLogic Server solution and applying Oracle JRF is not acceptable, consider using WLDF - WebLogic Diagnostic Framework. (Fusion Middleware Diagnostic Framework makes use of WLDF under the covers.) Couple of useful links about WLDF are listed below Configuring and Using the Diagnostics Framework for Oracle WebLogic Server 11g WebLogic Diagnostics Framework-A Very Useful Tool [A nice blog which describes a WLDF use case] How to Get Started With Diagnostic Framework To be frank, the Fusion Middleware Administrator's Guide is the best place to start your learning Oracle Fusion Middleware Administrator's Guide 11g Release 1 (11.1.1)Chapter 13 Diagnosing Problems A lot of reading here,  but if you are in hurry and just want to get the right information to Oracle Support to help resolve your issue, check out the next section below. How to Upload Diagnostic Framework Incident Data to Oracle Support Some Background Information There are three interfaces to the Repository: Enterprise Manager Cloud Control (Support Workbench) WLST (Command Line) ADRCI (Command Line) The Enterprise Manager Cloud Control does provide a nice GUI interface to search, view and package diagnostic framework incidents. However, this software is not to be confused with Fusion Middleware (EM) Control. Cloud Control (formerly known as Grid Control) is part of the Enterprise Manager media package. EM Cloud Control has it's own install and configuration story. Therefore, for the benefit of those yet to install and play with Cloud Control, I am going to describe how to use the command line tools. Ideally, you would only need to one command line interface, but currently I suggest using both - mainly due to the fact that ADRCI SHOW INCIDENTS does not reveal the description behind the Diagnostic Framework error code. Instructions: Note: WLST and ADRCI are case sensitive when it comes to handling parameter values. If you make a mistake, expect an unfriendly syntax error message. 1) Find the incident Note: The managed server which you are troubleshooting must be up and running. If the managed server is down, ensure the domain's Admin Server is accessible. If you cannot connect to the Admin Server or the Managed Server the example WLST commands will not work. a) Launch WLST  Note: Use the WLST which resides in the "oracle_common" directory (not WL_HOME/common/bin) otherwise you will get a syntax error like the one below Traceback (innermost last):  File "<console>", line 1, in ?NameError: listIncidents MW_HOME/oracle_common/common/bin/wlst.sh b) Connect to the managed server or the admin server e.g. wls:/offline> connect('weblogic','welcome1','t3://localhost:7020') c) Run the command wls:/MyDomain/serverConfig> listIncidents() This will list the incidents for the server to which you have connected. If you have connected to the Admin Server and want to list the incidents for a managed server within the domain, use the command wls:/MyDomain/serverConfig> listIncidents(adrHome='diag\ofm\MyDomain\MyManagedServer' ,server='MyManagedServer') Example output Incident Id     Problem Key              Incident Time         1       DFW-99998 [java.lang.NullPointerException] [oracle.error.simulator.ErrorSimulator.createNullPointerException][errorWebApp_1-0-0-0]        Fri Nov 02 10:38:46 GMT 2012  The piece highlighted in bold is the description you do not see when using the ADRCI 'SHOW INCIDENT' command. Make a note of the incident id. You are ready to move to step 2 2. Package the incident a) Set up the environment - example commands below are for Unix cd <DOMAIN_HOME>/bin . ./setDomainEnv.sh If you want ADRCI to run a Remote Diagnostic Agent collection (recommended) at generate package time, point ORACLE_HOME at oracle_common ORACLE_HOME=$MW_HOME/oracle_common; export ORACLE_HOME To prevent ADRCI from running RDA at generate package time, point ORACLE_HOME at WL_HOME/server/adr directory.  ORACLE_HOME=$WL_HOME/server/adr; export ORACLE_HOME b) Launch adrci $WL_HOME/server/adr/adrci c) Set BASE and HOMEPATH adrci> SET BASE /oracle/middleware/user_projects/domains/ mydomain/servers/mymanagedserver/adr adrci> SET HOMEPATH diag/ofm/mydomain/mymanagedserver d)  Optionally run SHOW INCIDENTS e.g. adrci> SHOW INCIDENTS -MODE DETAIL ADR Home = /oracle/middleware/user_projects/domains/mydomain/ servers/mymanagedserver/adr/diag/ofm/mydomain/mymanagedserver:***********************************************************************************************************************************INCIDENT INFO RECORD 1**********************************************************   INCIDENT_ID                   1   STATUS                        ready   CREATE_TIME                   2012-11-02 10:38:46.468000 +00:00   PROBLEM_ID                    1   CLOSE_TIME                    <NULL>   FLOOD_CONTROLLED              none   ERROR_FACILITY                DFW   ERROR_NUMBER                  99998   ERROR_ARG1                    <NULL>   ERROR_ARG2                    <NULL>   ERROR_ARG3                    <NULL>   ERROR_ARG4                    <NULL>   ERROR_ARG5                    <NULL>   ERROR_ARG6                    <NULL>   ERROR_ARG7                    <NULL>   ERROR_ARG8                    <NULL>   ERROR_ARG9                    <NULL>   ERROR_ARG10                   <NULL>   ERROR_ARG11                   <NULL>   ERROR_ARG12                   <NULL>   SIGNALLING_COMPONENT          <NULL>   SIGNALLING_SUBCOMPONENT       <NULL>   SUSPECT_COMPONENT             <NULL>   SUSPECT_SUBCOMPONENT          <NULL>   ECID                          5162744c6a2eea5e:155ff445:13ac0aae7cb:-8000-0000000000000325   IMPACTS                       01 rows fetched e)  Create a logical package IPS CREATE PACKAGE INCIDENT incident_number e.g. adrci> IPS CREATE PACKAGE INCIDENT 1Created package 1 based on incident id 1, correlation level typical f) Generate the package IPS GENERATE PACKAGE package_number IN path e.g. adrci> IPS GENERATE PACKAGE 1 IN /tmp Generated package 1 in file /tmp/DFW99998j_20121102113633_COM_1.zip, mode complete Note: If the generate package command hangs, ADRCI may be experiencing an issue when running RDA.

• Choosing the right language for the job

  - by Ampt

  I'm currently working for a company on the engineering team of about 5-6 people and have been given the job of heading up the redesign of an embedded system tester. We've decided the general requirements and attributes that would be desirable in the system, and now I have to decide on a language to use for the system, or at the very least come up with a list of languages with pros and cons to present to the team. The general idea of the project is that we currently have a tester written in c++, which was never designed to be a tester, but instead has evolved to be such over the course of 3-4 years due to need. Writing tests for a new product requires modifying the 'framework' and writing code that is completely non-human readable or intuitive due to the way the system was originally designed. Now, we've decided that the time to modify this tester for each new product that we want to test has become too high and want to partially re-write the system so that we can program the actual tests in a scripting language that would then use the modified c++ framework on the back end to test the actual systems. The c++ framework would be responsible for doing all the actual work and the scripting language would just integrate with that to tell the framework what to do. Never having programmed in a scripting language (we program embedded systems), I've run into a wall where I have no experience with any of the languages that we could possibly use, but must somehow give pros and cons of each language so that we can choose the best one for the job. Currently my short list of possibilities includes: Python TCL Lua Perl My question is this: How can a person evaluate a language that he/she has never used before? What criteria are good indicators for a languages potential usability on a project? While helpful suggestions for my particular case are appreciated, I feel that this is a good skill to possess and would like to be able to apply this to many different projects if at all possible

• Magento - How to manage multiple base currencies and multiple payment gateways?

  - by Diego

  I have two requirements to satisfy, I hope someone with more experience can help me sorting them out. Multiple Base Currencies My client wants to allow visitors to place orders in whatever currency they prefer, choosing from the ones he’ll configure. Magento only supports one Base Currency, and this is, obviously, not what I need. I checked the solution involving multiple websites, but I need a customer to be registered once and stay on the same website, not to switch from one to the other and have to register/log in on each. Manage multiple Payment Gateways per currency and per payment method This is another crucial requirement, and it’s tied to the first one. My client wants to “route” payments in different currencies to different accounts. He’ll thus have one for Euro, one for USD and one for GBP. Whenever a customer pays with one of these currencies, the payment gateway has to be chosen accordingly. Additionally, the gateway should be different depending on other rules. For example, if customer pays with a Debit Card, my client will have a payment gateway configured especially for it. If customer pays with MasterCard, the gateway will be different, and so on. The complication, in this case, arises from the fact that my client uses Realex Payments and, although it would be possible for him to open multiple accounts, the Realex module expects one single gateway. In a normal scenario, we would need up to six instead: Payment with Debit Card in Euro Payment with Credit Card in Euro Payment with Debit Card in US Dollars Payment with Credit Card in US Dollars Payment with Debit Card in GB Pounds Payment with Credit Card in GB Pounds This, of course, if he doesn’t decide to accept other payment methods, such as bank transfer, which would add one more gateway per currency. Is there a way to achieve the above in Magento? I never had such complicated requirements before, and I’m a bit lost. Thanks in advance for the help.

• Windows 7 USB power lose after a few seconds / minutes

  - by Stefan Dunn

  My friend's computer has a problem where the USB ports causes problems with the power of some devices connected to the computer. The USB mouse has no problems, however the Wireless Adapter looses power after around 20 seconds of use and USB Flash Drives cause the computer to either freeze, lose power (and become unresponsive) or become disconnected (still shown in Device Manager, but not in My Computer) when trying to transfer any type of file to / from the computer. I have a suspicion it's the Motherboard but could it also be a Software problem? Tried a new case, RAM, CPU and GFX Card which had no effect. The problem occurs on both the Front USB and Back (Motherboard) USB Ports. UPDATE: Tried the USB devices with an Ubuntu Live CD and they work fine, could this mean it's a problem with Windows (x64)?

• 1and1: Unable to host an external domain

  - by Django Reinhardt

  I'm sorry if this isn't the right place for this question, but I'm presently having difficulties with my hosting provider (1and1). Two weeks ago, two of my clients bought hosting from them on my recommendation, but as it turned out, 1and1 are having severe technical difficulties. Right now non of their hosting packages are able to accept ANY external domains. So either you pay the costs of transferring the registrar of your domain, or you use the ugly 1and1 domain name. Not any good for a hosting company of 1and1's reputation! They have been promising me for two weeks that they're going to fix the problem, but as you have probably guessed by now, that hasn't been the case. I would like to know if a) Anyone else is in the same boat as me, and b) If there are other comparably reputable hosting providers that I should consider moving to instead? Very disappointing! :( Note: This is for 1and1 in the UK. I imagine it isn't affecting users in other countries(?) Clarification: 1and1 are unable to accept ANY external domains. That means that even if you update your DNS details on your domain, their system cannot be updated to add your external domain to your account.

• Is anyone else using OpenBSD as a router in the enterprise? What hardware are you running it on?

  - by Kamil Kisiel

  We have an OpenBSD router at each of our locations, currently running on generic "homebrew" PC hardware in a 4U server case. Due to reliability concerns and space considerations we're looking at upgrading them to some proper server-grade hardware with support etc. These boxes serve as the routers, gateways, and firewalls at each site. At this point we're quite familiar with OpenBSD and Pf, so hesitant at moving away from the system to something else such as dedicated Cisco hardware. I'm currently thinking of moving the systems to some HP DL-series 1U machines (model yet to be determined). I'm curious to hear if other people use a setup like this in their business, or have migrated to or away from one.

• Hiding the Flash Message After a Time Delay

  - by Madhan ayyasamy

  Hi Friends,The flash hash is a great way to provide feedback to your users.Here is a quick tip for hiding the flash message after a period of time if you don’t want to leave it lingering around.First, add this line to the head of your layout to ensure the prototype and script.aculo.us javascript libraries are loaded:Next, add the following to either your layout (recommended), your view templates or a partial depending on your needs. I usually add this to a partial and include the partial in my layouts. "flash", :id = flash_type % "text/javascript" do % setTimeout("new Effect.Fade('');", 10000); This will wrap the flash message in a div with class=‘flash’ and id=‘error’, ‘notice’ or ‘warn’ depending on the flash key specified.The value ‘10000’ is the time in milliseconds before the flash will disappear. In this case, 10 seconds.This function looks pretty good and little javascript stunts like this can help make your site feel more professional. It’s also worth bearing in mind though, not everybody can see well or read as quickly as others so this may not be suitable for every application.Update:As Mitchell has pointed out (see comments below), it may be better to set the flash_type as the div class rather than it’s id. If there is the possibility that you’ll be showing more than one flash message per page, setting the flash_type as the div id will result in your HTML/XHTML code becoming invalid because the unique intentifier will be used more than once per page.Here is a slightly more complex version of the method shown above that will hide all divs with class ‘flash’ after a time delay, achieving the same effect and also ensuring your code stays valid with more than one flash message! "flash #{flash_type}" % "text/javascript" do % setTimeout("$$('div.flash').each(function(flash){ flash.hide();})", 10000); In this example, the div id is not set at all. Instead, each flash div will have class “div” and also class of the type of flash message (“error”, “warning” etc.).Have a Great Day..:)

• Running Non-profit Web Applications on Cloud/Dedicated Hosting [closed]

  - by cillosis

  Possible Duplicate: How to find web hosting that meets my requirements? I often times build web applications purely because I enjoy it. I like building useful tools or open source applications that don't come with a price tag. That being said, many of these applications can be quite complex requiring services beyond shared hosting (ex. specific PHP extensions). This leaves me with two options: Make the web application less complex and run on shared hosting. Fork out money for cloud or dedicated/VPS hosting. Considering the application is free (I don't make money off of it intentionally), the money for hosting comes out of my own pocket. I know I am not alone in this sticky situation. So the question is, what are the hosting options that provide more advanced features such as shell access via SSH, ability to install specific software/extensions (ex. if I wish to use a NoSQL DB such as Redis, MongoDB, or Cassandra), etc., at a free or low price point? I know free usually equates to bad/unreliable hosting -- but it's not always the case. There are a couple providers with free plans I know of: Amazon EC2 - Free micro-instance for 1 year AppHarbor - Cloud based .NET web application hosting w/ free plan. What else is available for hosting of non-profit applications?

• The Hot-Add Memory Hogs

  - by Andrew Clarke

  One of the more difficult tasks, when virtualizing a server, is to determine the amount of memory that Hypervisor should assign to the virtual machine. This requires accurate monitoring and, because of the consequences of setting the value too low, there is a great temptation to err on the side of over-provisioning. This results in fewer guest VMs and, in fact, with more accurate memory provisioning, many virtual environments could support 30% more VMs. In order to achieve a better consolidation (aka VM density) ratio, Windows Server 2008 R2 SP1 has introduced what Microsoft calls ‘Dynamic Memory’. This means that the start-up RAM VM memory assigned to guest virtual machines can be allowed to vary according to demand, changing dynamically while the VM is running, based on the workload of applications running inside. If demand outstrips supply, then memory can be rationed according to the ‘memory weight’ assigned to the guest VM. By this mechanism, memory becomes a shared resource that can be reallocated automatically as demand patterns vary. Unlike VMWare’s Memory Overcommit technology, the sum of all the memory allocations to each virtual machine will not exceed the total memory of the host computer. This is fine for applications that are self-regulating in their demands for memory, releasing memory back into the 'pool' when not under peak load. Other applications however, such as SQL Server Standard and Enterprise, are by nature, memory hogs under high workload; they can grab hot-add memory whilst running under load and then never release it. This requires more careful setting-up and the SQLOS team have provided some guidelines from for configuring SQL Server in virtual environments. Whereas VMWare’s Memory Overcommit is well-proven in a number of different configurations, Hyper-V’s ‘Dynamic Memory’ is new. So far, the indications are that it will improve the business case for virtualizing and it is probably a far more intuitive technology for the average IT professional to grasp. It is certainly worth testing to see whether it works for you.

• Boost your infrastructure with Coherence into the Cloud

  - by Nino Guarnacci

  Authors: Nino Guarnacci & Francesco Scarano,  at this URL could be found the original article:  http://blogs.oracle.com/slc/coherence_into_the_cloud_boost. Thinking about the enterprise cloud, come to mind many possible configurations and new opportunities in enterprise environments. Various customers needs that serve as guides to this new trend are often very different, but almost always united by two main objectives: Elasticity of infrastructure both Hardware and Software Investments related to the progressive needs of the current infrastructure Characteristics of innovation and economy. A concrete use case that I worked on recently demanded the fulfillment of two basic requirements of economy and innovation.The client had the need to manage a variety of data cache, which can process complex queries and parallel computational operations, maintaining the caches in a consistent state on different server instances, on which the application was installed.In addition, the customer was looking for a solution that would allow him to manage the likely situations in load peak during certain times of the year.For this reason, the customer requires a replication site, on which convey part of the requests during periods of peak; the desire was, however, to prevent the immobilization of investments in owned hardware-software architectures; so, to respond to this need, it was requested to seek a solution based on Cloud technologies and architectures already offered by the market. Coherence can already now address the requirements of large cache between different nodes in the cluster, providing further technology to search and parallel computing, with the simultaneous use of all hardware infrastructure resources. Moreover, thanks to the functionality of "Push Replication", which can replicate and update the information contained in the cache, even to a site hosted in the cloud, it is satisfied the need to make resilient infrastructure that can be based also on nodes temporarily housed in the Cloud architectures. There are different types of configurations that can be realized using the functionality "Push-Replication" of Coherence. Configurations can be either: Active - Passive  Hub and Spoke Active - Active Multi Master Centralized Replication Whereas the architecture of this particular project consists of two sites (Site 1 and Site Cloud), between which only Site 1 is enabled to write into the cache, it was decided to adopt an Active-Passive Configuration type (Hub and Spoke). If, however, the requirement should change over time, it will be particularly easy to change this configuration in an Active-Active configuration type. Although very simple, the small sample in this post, inspired by the specific project is effective, to better understand the features and capabilities of Coherence and its configurations. Let's create two distinct coherence cluster, located at miles apart, on two different domain contexts, one of them "hosted" at home (on-premise) and the other one hosted by any cloud provider on the network (or just the same laptop to test it :)). These two clusters, which we call Site 1 and Site Cloud, will contain the necessary information, so a simple client can insert data only into the Site 1. On both sites will be subscribed a listener, who listens to the variations of specific objects within the various caches. To implement these features, you need 4 simple classes: CachedResponse.java Represents the POJO class that will be inserted into the cache, and fulfills the task of containing useful information about the hypothetical links navigation ResponseSimulatorHelper.java Represents a link simulator, which has the task of randomly creating objects of type CachedResponse that will be added into the caches CacheCommands.java Represents the model of our example, because it is responsible for receiving instructions from the controller and performing basic operations against the cache, such as insert, delete, update, listening, objects within the cache Shell.java It is our controller, which give commands to be executed within the cache of the two Sites So, summarily, we execute the java class "Shell", asking it to put into the cache 100 objects of type "CachedResponse" through the java class "CacheCommands", then the simulator "ResponseSimulatorHelper" will randomly create new instances of objects "CachedResponse ". Finally, the Shell class will listen to for events occurring within the cache on the Site Cloud, while insertions and deletions are performed on Site 1. Now, we realize the two configurations of two respective sites / cluster: Site 1 and Site Cloud.For the Site 1 we define a cache of type "distributed" with features of "read and write", using the cache class store for the "push replication", a functionality offered by the project "incubator" of Oracle Coherence.For the "Site Cloud" we expect even the definition of “distributed” cache type with tcp proxy feature enabled, so it can receive updates from Site 1.  Coherence Cache Config XML file for "storage node" on "Site 1" site1-prod-cache-config.xml Coherence Cache Config XML file for "storage node" on "Site Cloud" site2-prod-cache-config.xml For two clients "Shell" which will connect respectively to the two clusters we have provided two easy access configurations.  Coherence Cache Config XML file for Shell on "Site 1" site1-shell-prod-cache-config.xml Coherence Cache Config XML file for Shell on "Site Cloud" site2-shell-prod-cache-config.xml Now, we just have to get everything and run our tests. To start at least one "storage" node (which holds the data) for the "Cloud Site", we can run the standard class  provided OOTB by Oracle Coherence com.tangosol.net.DefaultCacheServer with the following parameters and values:-Xmx128m-Xms64m-Dcom.sun.management.jmxremote -Dtangosol.coherence.management=all -Dtangosol.coherence.management.remote=true -Dtangosol.coherence.distributed.localstorage=true -Dtangosol.coherence.cacheconfig=config/site2-prod-cache-config.xml-Dtangosol.coherence.clusterport=9002-Dtangosol.coherence.site=SiteCloud To start at least one "storage" node (which holds the data) for the "Site 1", we can perform again the standard class provided by Coherence  com.tangosol.net.DefaultCacheServer with the following parameters and values:-Xmx128m-Xms64m-Dcom.sun.management.jmxremote -Dtangosol.coherence.management=all -Dtangosol.coherence.management.remote=true -Dtangosol.coherence.distributed.localstorage=true -Dtangosol.coherence.cacheconfig=config/site1-prod-cache-config.xml-Dtangosol.coherence.clusterport=9001-Dtangosol.coherence.site=Site1 Then, we start the first client "Shell" for the "Cloud Site", launching the java class it.javac.Shell  using these parameters and values: -Xmx64m-Xms64m-Dcom.sun.management.jmxremote -Dtangosol.coherence.management=all -Dtangosol.coherence.management.remote=true -Dtangosol.coherence.distributed.localstorage=false -Dtangosol.coherence.cacheconfig=config/site2-shell-prod-cache-config.xml-Dtangosol.coherence.clusterport=9002-Dtangosol.coherence.site=SiteCloud Finally, we start the second client "Shell" for the "Site 1", re-launching a new instance of class  it.javac.Shell  using  the following parameters and values: -Xmx64m-Xms64m-Dcom.sun.management.jmxremote -Dtangosol.coherence.management=all -Dtangosol.coherence.management.remote=true -Dtangosol.coherence.distributed.localstorage=false -Dtangosol.coherence.cacheconfig=config/site1-shell-prod-cache-config.xml-Dtangosol.coherence.clusterport=9001-Dtangosol.coherence.site=Site1  And now, let’s execute some tests to validate and better understand our configuration. TEST 1The purpose of this test is to load the objects into the "Site 1" cache and seeing how many objects are cached on the "Site Cloud". Within the "Shell" launched with parameters to access the "Site 1", let’s write and run the command: load test/100 Within the "Shell" launched with parameters to access the "Site Cloud" let’s write and run the command: size passive-cache Expected result If all is OK, the first "Shell" has uploaded 100 objects into a cache named "test"; consequently the "push-replication" functionality has updated the "Site Cloud" by sending the 100 objects to the second cluster where they will have been posted into a respective cache, which we named "passive-cache". TEST 2The purpose of this test is to listen to deleting and adding events happening on the "Site 1" and that are replicated within the cache on "Cloud Site". In the "Shell" launched with parameters to access the "Site Cloud" let’s write and run the command: listen passive-cache/name like '%' or a "cohql" query, with your preferred parameters In the "Shell" launched with parameters to access the "Site 1" let’s write and run the following commands: load test/10 load test2/20 delete test/50 Expected result If all is OK, the "Shell" to Site Cloud let us to listen to all the add and delete events within the cache "cache-passive", whose objects satisfy the query condition "name like '%' " (ie, every objects in the cache; you could change the tests and create different queries).Through the Shell to "Site 1" we launched the commands to add and to delete objects on different caches (test and test2). With the "Shell" running on "Site Cloud" we got the evidence (displayed or printed, or in a log file) that its cache has been filled with events and related objects generated by commands executed from the" Shell "on" Site 1 ", thanks to "push-replication" feature.  Other tests can be performed, such as, for example, the subscription to the events on the "Site 1" too, using different "cohql" queries, changing the cache configuration,  to effectively demonstrate both the potentiality and  the versatility produced by these different configurations, even in the cloud, as in our case. More information on how to configure Coherence "Push Replication" can be found in the Oracle Coherence Incubator project documentation at the following link: http://coherence.oracle.com/display/INC10/Home More information on Oracle Coherence "In Memory Data Grid" can be found at the following link: http://www.oracle.com/technetwork/middleware/coherence/overview/index.html To download and execute the whole sources and configurations of the example explained in the above post,  click here to download them; After download the last available version of the Push-Replication Pattern library implementation from the Oracle Coherence Incubator site, and download also the related and required version of Oracle Coherence.

• Running evrouter at boot with init.d, or after xserver starts

  - by J V

  I'm using evrouter to set up mouse button binds, and init.d to start it. My init.d file: #!/bin/bash #Simple init.d script to run evrouter ### BEGIN INIT INFO # Provides: evrouter # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Set evrouter bindings # Description: Set evrouter bindings at boot time. ### END INIT INFO config="/opt/hacks/evrouterrc" case "$1" in start|restart|reload|force-reload) evrouter -c "$config" /dev/input/event* ;; stop) echo "Evrouter is not a daemon, change settings file at '$config' and restart" ;; *) echo "Usage: $0 start" >&2 exit 3 ;; esac evrouter however complains that: evrouter: could not open display "". If evrouter requires xserver to be up, how do I get init to wait until after xserver starts to run this script? If xserver restarts will this script run automatically? Running this with sudo services evrouter start still results in this error, can init.d scripts not tell where my display is? (Not exactly familiar with init, runlevels, etc)

• Cannot access Windows 7 share from Windows XP

  - by artfulrobot

  I have a new Windows 7 machine named PAP44 in the PAP workgroup. The networking is set to "Work" mode for the wired LAN. I have a couple of users and I've shared a folder and set it so both users can read/write. Confusingly for me, rather than sharing just that folder (as I'm used to with older versions of Windows) it appears to be sharing a path (\\pap44\users\...\myFolder) From another machine on the LAN, running XP, when I go to \\PAP44\Users I'm asked for a username and password, but neither of the usernames+passwords work. It just jumps back to the username and password dialogue, except that the username I entered gets prefixed with PAP44\ My end goal is to get my Debian/Ubuntu machines to be able to access this share, but first of all I thought I'd try to get it working in Windows, after all, that's supposed to be easy! Is there another step? (PS. I am not a "hit and run" case!)

• Looking for a software to keep track of backup media

  - by Tarnschaf

  Hi, I am looking for a software that allows me to enter my used backup media (e.g. DVD1, DVD2) my backed-up assets in high-level (such as "family-photos from 2003", "laptop drivers") details of the assets ("Ninas Birthday 2003") where the backup media is currently stored when the media has been burned (to re-burn in case of media degeneration) Of course it should be possible to navigate from media to assets and backwards. I also thought about marking assets as "deprecated". If all assets on a media are deprecated, the program should tell me so I don't have to keep it any more. Does anybody know a program with this feature-set or will I have to start my own in say Access?

• How to do hooking in Java? [closed]

  - by chimpaburro

  A hook is a process running to get data from another (more info), well the case was that I wanted to get the methods or functions using any application for access to a network, these methods are usually WSAConnect (), WSASendTo (), bind (), connect () and sendto () [these are the ones that need to get to the application]. I started testing, creating Runtime [Runtime.getRuntime (). exec (...)] with all possible methods [addShutdownHook (...);] and now I'm trying to ProcessBuilder [new ProcessBuilder (...);] and the famous BufferedReader [new BufferedReader (new InputStreamReader (proceso.getInputStream ()));] but I could not find the way to do it. Sorry for my bad English..

• WCF Versioning, Naming and Endpoint URL

  - by Vinothkumar VJ

  I have a WCF Service and a Main Lib1. Say, I have a Save Profile Service. WCF gets data (with predefined data contract) from client and pass the same to the Main Class Lib1, generate response and send it back to client. WCF Method : SaveProfile(ProfileDTO profile) Current Version 1.0 ProfileDTO have the following UserName Password FirstName DOB (In string yyyy-mm-dd) CreatedDate (In string yyyy-mm-dd) Next Version (V2.0) ProfileDTO have the following UserName Password FirstName DOB (In UnixTimeStamp) CreatedDate (In UnixTimeStamp) Version 3.0 ProfileDTO have the following (With change in UserName and Password length validation) UserName Password FirstName DOB (In UnixTimeStamp) CreatedDate (In UnixTimeStamp) In simple we have DataContract and Workflow change between each version 1. How do I name the methods in WCF Service and Main Class Lib1? 2. Do I have to go with any specific pattern for ease development and maintenance? 3. Do I have to have different endpoints for different version? In the above example I have a method named “SaveProfile”. Do I have to name the methods like “SaveProfile1.0”, “SaveProfile2.0”, etc. If that is the case when there is no change between Version “3.0” and “4.0” then there will difficult in maintenance. I’m looking for a approach that will help in ease maintenance

• How do I get nginx to issue 301 requests to HTTPS location, when SSL handled by a load-balancer?

  - by growse

  I've noticed that there's functionality enabled in nginx by default, whereby a url request without a trailing slash for a directory which exists in the filesystem automatically has a slash added through a 301 redirect. E.g. if the directory css exists within my root, then requesting http://example.com/css will result in a 301 to http://example.com/css/. However, I have another site where the SSL is offloaded by a load-balancer. In this case, when I request https://example.com/css, nginx issues a 301 redirect to http://example.com/css/, despite the fact that the HTTP_X_FORWARDED_PROTO header is set to https by the load balancer. Is this an nginx bug? Or a config setting I've missed somewhere?

• Evolution of an Application: how to manage and improve core engine?

  - by Phil Carter

  The web application I work on has been live for a year now, but it's time for it to evolve and one of the ways in which it is evolving is into a multi-brand application - in this case several different companies using the application, different templates/content and some slight business logic changes between them. The problem I'm facing is implementing a best practice across the site where there are differences in business logic for each brand. These will mostly be very superficial, using a an alternative mailing list provider or capturing some extra data in a form. I don't want to have if(brand === x) { ... } else { ... } all over the site especially as most of what needs to be changed can be handled with extending the existing class. I've thought of several methods that could be used to instantiate the correct class, but I'm just not sure which is going to be best especially as some seem to lead to duplication of more code than should be necessary. Here's what I've considered: 1) Use a Static Loader similar to Zend_Loader which can take the class being requested, and has knowledge of the Brand and can then return the correct object. $class = App_Loader::getObject('User', $brand); 2) Factory classes. We use these in the application already for Products but we could utilise them here also to provide a transparent interface to the class. 3) Routing the page request to a specific brand controller. This however seems like it would duplicate a lot of code/logic. Is there a pattern or something else I should be considering to solve this problem? 4) How to manage a growing project that has multiple custom instances in production? Update This is a PHP application so the decisions on which class to load are made per request. There could be upwards of 100+ different 'brands' running.

• What should be the architecture of an urban game system?

  - by pmichna

  I'm going to develop an urban game using a telco API for phone geolocation and sending/receiving messages. A player would pick up one of the scenarios, move around the city and when he hits a given location, he gets a message and possibly has to answer it. I'm wondering, what approach would be the best in my case. I came up with this general idea: Web application as a user interface (user registration, players ranking, scenarios editing) written in Ruby on Rails. Game server (hosting games, game logic like checking players location, sending and receiving messages) written in Ruby. Database (users, scores, scenarios etc.), probably MySQL or someother open source DB. I want to learn Ruby and RoR, that's why I chose these language and framework. Do you think it's a good choice for a game server? Another question: is this project division good? I mean, I have little experience with Ruby and Rails - that's why I'm asking. Maybe it's better to have web application merged with game server and somehow have the server hosting RoR application do the tasks like mobile phone pinging and message sending? How would that be performed? Maybe this is worth mentioning: the API is RESTful, most results are JSON, few are XML.

• Integration of routes that are not resources in an MVC REST style application

  - by Emil Lerch

  I would like to keep my application relatively REST-pure for the sake of consistency, but I'm struggling philosophically with the relatively few views (maybe just one) that I'll need to build that don't relate to resources directly, and therefore do not fit into a REST style. As an example, take the home page. Ruby on rails seems to bail on their otherwise RESTful approach for this very basic need of all web sites. The home page appears special: You can get it, but a get at the resource level is supposed to give you a collection of elements. I can imagine this being the list of routes maybe, but that seems a stretch, and doesn't address anything else. Getting the home page by id doesn't seem to make a whole lot of sense - what's the element of a home collection? Again, maybe routes, but a get on a route would do what? Redirect? This feels odd. You can't delete it (arguably you could allow this for administrators) Adding a second one doesn't make sense except possibly if the elements were routes Updating it might make sense for administrators, but AFAIK REST doesn't describe updates on the resource directly, only elements of the resource (this article explicitly says "UNUSED" for PUTS on the resource) Is the "right" thing to do just to special case these types of things? At the end of the day, I can wrap my head around most of applications being gathered around resources...I can't think of another good example other than a home page, but since that's the start of an application, I think it warrants some thought.

• One-way forest trust between geographically distributed forests using Server 2008 R2

  - by bwerks

  Hi all, I'm planning out a joinder between two domains, as would take place with contracting companies. Forests A and B exist in distant sites, and there is to be a one-way forest trust so that domain users in Forest A can be authenticated on machines in Forest B. In order to facilitate this, each forest's domain controller must be able to contact each other in order to set up & confirm the trust, but my question is what underlying networking magic must take place beneath it. So far the prevailing approach has been to maintain a VPN connection between the two sites, but the technet documentation seems to indicate that DNS forwarding may be the way to go. Is this the case? Furthermore, if DNS will suffice, does that mean that there must be a server running DNS on boundary servers in each domain so that they can be reached from across the internet? How must they be configured? Thanks!

• Ganglia and how it communicates

  - by MikeKulls

  I'm a little confused about how Ganglia sends information around and have found conflicting information on the web. I would have thought that the gmond process would either send info to gmetad at a regular interval or gmetad would request info from the various instances of gmond. At least one online article states this is how it works but from what I understand this is incorrect. It appears that you configure all gmond processes to send their info to a central gmond process and gmetad will request info from that central gmond. Is that correct? In my case I have 6 servers sending their information to 1 central server. If I set gmetad to get it's information from the central server then I get information from all 6 servers, all good.. Their weird thing is that if I point gmetad to one of the 6 servers then I still get info from all 6 servers. How is it that server 1 in my cluster if getting stats from all the other servers?

• What's Your Favorite Harmless Computer Practical Joke?

  - by Ben Griswold

  A couple of months ago, I returned from lunch to find that typing any key launched a random application. As I always lock my machine before walking away from it, my first thought was that a co-worker was playing a practical joke on me. As it turned out, the cause was random computer wonkiness. But just in case there's a need :), what's your favorite harmless computer practical joke? For example, would you alter host file entries to direct google.com to a random site or would you put tape over the optical sensor of a co-worker’s mouse?

• How to ...set up new Java environment - largely interfaces...

  - by Chris Kimpton

  Hi, Looks like I need to setup a new Java environment for some interfaces we need to build. Say our system is X and we need to interfaces to systems A, B and C. Then we will be writing interfaces X-A, X-B, X-C. Our system has a bus within it, so the publishing on our side will be to the bus and the interface processes will be taking from the bus and mapping to the destination system. Its for a vendor based system - so most of the core code we can't touch. Currently thinking we will have several processes, one per interface we need to do. The question is how to structure things. Several of the APIs we need to work with are Java based. We could go EJB, but prefer to keep it simple, one process per interface, so that we can restart them individually. Similarly SOA seems overkill, although I am probably mixing my thoughts about implementations of it compared to the concepts behind it... Currently thinking that something Spring based is the way to go. In true, "leverage a new tech if possible"-style, I am thinking maybe we can shoe horn some jruby into this, perhaps to make the APIs more readable, perhaps event-machine-like and to make the interface code more business-friendly, perhaps even storing the mapping code in the DB, as ruby snippets that get mixed in... but thats an aside... So, any comments/thoughts on the Spring approach - anything more up-to-date/relevant these days. EDIT: Looking a JRuby further, I am tempted to write it fully in JRuby... in which case do we need any frameworks at all, perhaps some gems to make things clearer... Thanks in advance, Chris
