• Hosted EBS 11i Integration Repository Temporarily Offline

  - by Steven Chan (Oracle Development)

  Most developers know that they can integrate their external applications with the E-Business Suite via the business service interfaces and SOA service endpoints documented in the E-Business Suite's Integration Repository.  This is shipped as part of EBS 12.  Until recently, it was provided as a hosted environment on the Oracle.com domain for EBS 11i. Unfortunately, we identified some standards-related issues in the process of switching from the existing server that hosts the EBS 11i environment to a new one, notably in the area of accessibility. Some of those issues will require coding changes to resolve.  Given our focus on EBS 12.2 right now, it may take some time to prioritize this relative to our other existing commitments. In the meantime, we are required to suspend access to the EBS 11i Integration Repository.  I don't have a firm schedule for getting this back online yet, but you're welcome to monitor or subscribe to this blog. I'll post updates here as soon as soon as they're available.    Related Articles Integration Repository for the E-Business Suite New Whitepaper: Primer on Integrating with EBS 12 with Other Applications

• Enabling SFTP Access within PLESK

  - by spelley

  I have a client who wants to ensure his upload is secure, so we are trying to enable SFTP for him on our Linux PLESK server. I have enabled SSH access to bin/bash for FTP accounts, and created a new user. When I attempt to SFTP using either the IP address or the domain name, this is the error FileZilla is giving me: Error: Authentication failed. Error: Critical error Error: Could not connect to server Here is some basic information regarding the server: Operating system Linux 2.6.24.5-20080421a Plesk Control Panel version psa v8.6.0_build86080930.03 os_CentOS 5 I had read in some places that I should reboot the SSH Service in Server - Services, however, there is no SSH Service within the list. I'm not really a server guy so it's quite possible I'm missing something obvious. Thanks for any help that you guys can provide!

• VMware ESX 3.5 Host Health shown as unknown

  - by dunxd

  I have an ESX 3.5 update 5 cluster of five host servers, all fully patched as of this Friday. Today I noticed that one of the servers has the Hardware Health status as unknown in Virtual Center Infrastructure Client. When I look at the Health Status view under configuration for that host, all the items are status Unknown. The server is exactly the same configuration as the others - same model (HP DL360 G5), memory, NICs etc. I have tried restarting the management service with service mgmt-vmware restart but this has not resolved the issue. Asides from this, I am not seeing any issues with the cluster - however, I hate having a blind spot like this. Any ideas?

• Relationship between SOA and OOA

  - by TheSilverBullet

  Thomas Erl defines SOA as follows in his site: Service-oriented computing represents a new generation distributed computing platform. As such, it encompasses many things, including its own design paradigm and design principles, design pattern catalogs, pattern languages, a distinct architectural model, and related concepts, technologies, and frameworks. This definitely sounds like a whole new category which is parallel to object orientation. Almost one in which you would expect an entirely new language to exist for. Like procedural C and object oriented C#. Here is my understanding: In real life, we don't have entirely new language for SOA. And most application which have SOA architecture have an object oriented design underneath it. SOA is a "strategy" to make the entire application/service distributed and reliable. SOA needs OOPS working underneath it. Is this correct? Where does SOA (if at all it does) fit in with object oriented programming practices? Edit: I have learnt through answers that OOA and SOA work with each other and cannot be compared (in a "which is better" way). I have changed the title to "Relationship between SOA and OOA" rather than "comparison".

• Ubuntu 13.04 ERROR: /etc/apt/sources.list not found

  - by Richard Riley

  So, I tried uninstalling the LAMP stack I had following the Ubuntu documentation for it. I also manually removed dbconfig-common. Now, I'm unable to run apt-get update. When I do, I get the error message: E: The method driver /usr/lib/apt/methods/htp could not be found. After some digging, I've discovered that I no longer even have an /etc/apt/sources.list file. Also, I've received an error, when trying to run: sudo tasksel install lamp-server That aptitude can not be found. Does anyone have an idea of what I can do? I'm not able to find any documentation online that works - all the documentation out there is dated and no longer (or will not) work with 13.04. I followed this link previously prior to posting my question and it did not work for me: How do I fix a "E: The method driver /usr/lib/apt/methods/http could not be found." error?

  first of all, I want to create shell script to start/stop downloads in torrent client. I don't need CLI but if you know how I can do that with CLI using shell script then it is okay. I use jDownloader which is GUI based application but has some command line arguments as below which I use to start/stop download. -h/--help Show this help message -a/--add-link(s) Add links -co/--add-container(s) Add containers -d/--start-download Start download -D/--stop-download Stop download -H/--hide Don't open Linkgrabber when adding Links -m/--minimize Minimize download window -f/--focus Get jD to foreground/focus -s/--show Show JAC prepared captchas -t/--train Train a JAC method -r/--reconnect Perform a Reconnect -C/--captcha <filepath or url> <method> Get code from image using JAntiCaptcha -p/--add-password(s) Add passwords -n --new-instance Force new instance if another jD is running So I can easily start/stop download as follows, jdownloader --start-download jdownloader --stop-download now I want torrent client to do that through shell script.

• Dedicated server: managed hosting or manage it myself?

  - by ddawber

  We're currently hosting a number of sites on a self-managed dedicated server. Some companies, however, offer a managed dedicated server hosting service. They offer: Roughly the same server spec Ticketing system support Managed daily backups Virtual firewall (but with a limit of 10 IP addresses allowed through at any one time) Now, this managed hosting is at extra expense - somewhere in the region of $500 per month, and the limit on the number of IP addresses they'll manage on the firewall is also a real pain. My thinking is it would be better and cheaper to Stay with the same host since the dedicated box is fine Get an Amazon AWS account and use their server to manage backups; there are a number of good tools that can be used to automate the process Configure iptables so that I have complete control of the firewall I want to know Is a managed virtual firewall likely to be more secure than me configuring iptables? Whether, in your opinion, it's best to let someone else take care of backups? If, from your experience, there's anything else i'm missing that warrants using managed hosting over a DIY service? I think there is some reluctance to not having managed hosting since a managed host in effect takes responsibility for your server, whereas any hardware or security issues with a server that we manage would mean we are forced to hold our hands up when a client site goes down. That said, I personally don't think a managed host does that much in the day to day running of your server (backups are automatic, OS updates are carried out with ease, etc.).

• Creating a DrawableGameComponent

  - by Christian Frantz

  If I'm going to draw cubes effectively, I need to get rid of the numerous amounts of draw calls I have and what has been suggested is that I create a "mesh" of my cubes. I already have them being stored in a single vertex buffer, but the issue lies in my draw method where I am still looping through every cube in order to draw them. I thought this was necessary as each cube will have a set position, but it lowers the frame rate incredibly. What's the easiest way to go about this? I have a class CubeChunk that inherits Microsoft.Stuff.DrawableGameComponent, but I don't know what comes next. I suppose I could just use the chunk of cubes created in my cube class, but that would just keep me going in circles and drawing each cube individually. The goal here is to create a draw method that draws my chunk as a whole, and to not draw individual cubes as I've been doing.

• Are there any significant advantages to using a native language for mobile app development?

  - by Karl Daniel

  Forgive me if this question has already been answered but I couldn't quite find the answer I was looking for. What I wanted to know was, is there any significant advantage to using a native language when developing and deploying apps to a mobile environment? The reason I ask is for a long while now I've been using Objective-C, Apple's native language for iOS, to build my apps. However I've been wondering whether or not there is any real benefit to doing this, over using a non-native language like JavaScript and then deploying it through a service like 'Phone Gap'? I do stress 'significant' advantages as native languages are always more likely to have the upper hand when it comes to speed and access to the latest APIs. However in general I don't see using a non-native language or a service like 'Phone Gap' causing and major slow down to my apps or restricting my development. Additionally having the ability to deploy to multiple services is also very handy indeed. This is why I put the question, are there any significant advantages to using a native language for mobile app development?

• Passing variables from PHP to C++

  - by Alex

  I’m new to this so I’m sorry if my question is trivial. I have the following situation: I need to call a program from PHP and pass some vars and/or sets of key-value pairs to it. Now, my question is: how do I pass these vars, through arguments to the called function (e.g. exec("/path/to/program flag1 flag2 [key1=A,key2=B]");)? Or is there a better method to achieve this? Somebody suggested me to write them into a txt file and pass the path to it to as an argument instead (e.g. exec("/path/to/program path_to_txt_file);), but I’m not to excited about this method.

• ManagementObjectSearcher error [migrated]

  - by Piotrek

  Some of our customers inform us that in some cases following error appears: System.Management.ManagementException: Blad dostawcy. at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode) at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext() The error is generated while trying to loop through a colection returned by Get() method of the System.Mamangment.ManagementObjectSearcher object. This is the code of my method: private bool PrinterExists(string printerName) { bool retVal = false; SelectQuery q = new SelectQuery("select caption from win32_printer"); using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(q)) { foreach (ManagementObject printer in searcher.Get()) { if(printer["Caption"].ToString() == printerName) { retVal = true; break; } } } return retVal; } It seems that the problem appears only on Windows XP. The only workaround I know is reconstruction of WMI database. It sometimes helps, but unfortunatelly not always. Can anyone tell me what is the reason of this error and how can I fix it?

• Unable to log into samba server

  - by Paddington

  I am unable to log into a samba server (running on fedora core 6) as it prompts for a username and password when I try to connect to the mapped drives from my windows 7 machine. I decided to reset the password using the command smbpassword paddy and when I list users using check the pdbedit -L -v I see that the password was updated at the time I made this change. However, I am still unable to log in. The log file in /var/log/samba/log.paddy shows: [2012/10/11 09:55:54.605923, 1] smbd/service.c:678(make_connection_snum) create_connection_server_info failed: NT_STATUS_ACCESS_DENIED [2012/10/11 09:55:54.606635, 1] smbd/service.c:678(make_connection_snum) create_connection_server_info failed: NT_STATUS_ACCESS_DENIED How can I resolve this so that I can log in?

• Texture not drawing on cubes

  - by Christian Frantz

  I can draw the cubes fine but they are just solid black besides the occasional lighting that goes on. The basic effect is being set for each cube also. public void Draw(BasicEffect effect) { foreach (EffectPass pass in effect.CurrentTechnique.Passes) { pass.Apply(); device.SetVertexBuffer(vertexBuffer); device.Indices = indexBuffer; device.DrawIndexedPrimitives(PrimitiveType.TriangleList, 0, 0, 8, 0, 12); } } The cubes draw method. TextureEnabled is set to true in my main draw method. My texture is also loading fine. public Cube(GraphicsDevice graphicsDevice, Vector3 Position, Texture2D Texture) { device = graphicsDevice; texture = Texture; cubePosition = Position; effect = new BasicEffect(device); } The constructor seems fine too. Could this be caused by the Vector2's of my VertexPositionNormalTexture? Even if they were out of order something should still be drawn other than a black cube

• Is there a way to avoid type-checking in this scenario?

  - by Prog

  I have a class SuperClass with two subclasses SubClassA and SubClassB. I have a method in a different class which takes a SuperClass parameter. The method should do different things depending on the type of the object it receives. To illustrate: public void doStuff(SuperClass object){ // if the object is of type SubClassA, do something. // if it's of type SubClassB, do something else. } I want to avoid type-checking (i.e. instanceof) because it doesn't feel like proper OO design. But I can't figure out how to employ Polymorphism to elegantly solve this problem. How can I solve this problem elegantly?

• My internship mentor doesn't allow me to do anything my way [closed]

  When I started my internship, I was assigned a project. My internship mentor told he would just guide me if there was any problem. I started reading research papers and other works related to my project and completely understood it. But, when I started to implement my design, since then my mentor always order me to do things his way even though his method is crap. There are some things which can't be done but he wants results using his method (not possible). Because of him, I have lost all my interest from project. What to do?

• Caching by in-memory dictionaries. Are we doing it all wrong?

  - by user73983

  This approach is pretty much the accepted way to do anything in our company. A simple example : when a piece of data for a customer is requested from a service, we fetch all the data for that customer(relevant part to the service) and save it in a in-memory dictionary then serve it from there on following requests(we run singleton services). Any update goes to DB, then updates the in memory dictionary. It seems all simple and harmless but as we implement more complicated business rules the cache gets out of sync and we have to deal with hard to find bugs. Sometimes we defer writing to database, keeping new data in cache till then. There are cases when we store millions of rows in memory because the table has many relations to other tables and we need to show aggregate data quickly. All this cache handling is a big part of our codebase and I sense this is not the right way to do it. All of this juggling adds too much noise to the code and it makes it hard to understand the actual business logic. However I don't think we can serve data in a reasonable amount of time if we have to hit the database every time. I am unhappy about the current situation but I don't have a better alternative. My only solution would be to use NHibernate 2nd level cache but I have nearly no experience with it. I know many campanies use Redis or MemCached heavily to gain performance but I have no idea how I would integrate them into our system. I also don't know if they can perform better than in-memory data structures and queries. Are there any alternative approaches that I should look into?

• Worker processes not starting in IIS 7.5. What should I check?

  - by locster

  I have a Windows 7 machine (Windows version 6.1.7601 SP1 Build 7601) with IIS installed. At some point the installation appears to have become 'corrupted' in some way, as any requests are now met with the message: Service Unavailable HTTP Error 503. The service is unavailable. In IIS manager IIS is started and the app pool I am using reports itself as 'Started', yet there is no w3wp.exe process listed in the process list in task manager (I am a local admin and have clicked the 'Show processes from all users' button. I have enabled logging for the web site (at default location of %SystemDrive%\inetpub\logs\LogFiles), but this folder is empty. I am assuming that this log output is written by w3wp.exe as it handles requests (no w3wp.exe, no log file?). Presumably there is another layer of request handling that is responsible for starting the worker processes, does thsi layer have log files I can check, and/or can I uninstall/re-install that layer? Thanks.

• Why is apt-cache so slow?

  - by Damn Terminal

  After upgrade to Trusty (14.04) from Saucy (13.10), all apt operations are very slow. Even those that do not include downloading anything, or connecting to any servers. For example, displaying the apt policy # time apt-cache policy [...] real 0m8.951s user 0m5.069s sys 0m3.861s takes almost ten seconds! Mostly a weird lag right after issuing the command. And it's the same even if I issue the same command again. On another system it doesn't take a tenth of a second real 0m0.096s user 0m0.070s sys 0m0.023s The other system is a little beefier but there was no noticeable difference before the upgrade. It's the same with apt-get, anything apt-related. How do I find out the source of this lag and fix it? Additional info: # cat /etc/nsswitch.conf # /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality. # If you have the `glibc-doc-reference' and `info' packages installed, try: # `info libc "Name Service Switch"' for information about this file. passwd: compat group: compat shadow: compat hosts: files dns networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis BTW is my understanding of how apt-cache works correct? It doesn't make any network connections when I run apt-cache policy, right? In case I'm wrong and it matters, here are my sources https://gist.github.com/anonymous/02920270ff68e23fc3ec
