  - by charlie.berger

  Oracle Introduces Oracle Communications Data Model to Provide Actionable Insight for Communications Service Providers   We've integrated pre-installed analytical methodologies with the new Oracle Communications Data Model to deliver automated, simple, yet powerful predictive analytics solutions for customers.  Churn, sentiment analysis, identifying customer segments - all things that can be anticipated and hence, preconcieved and implemented inside an applications.  Read on for more information! TM Forum Management World, Nice, France - 18 May 2010 News Facts To help communications service providers (CSPs) manage and analyze rapidly growing data volumes cost effectively, Oracle today introduced the Oracle Communications Data Model. With the Oracle Communications Data Model, CSPs can achieve rapid time to value by quickly implementing a standards-based enterprise data warehouse that features communications industry-specific reporting, analytics and data mining. The combination of the Oracle Communications Data Model, Oracle Exadata and the Oracle Business Intelligence (BI) Foundation represents the most comprehensive data warehouse and BI solution for the communications industry. Also announced today, Hong Kong Broadband Network enhanced their data warehouse system, going live on Oracle Communications Data Model in three months. The leading provider increased its subscriber base by 37 percent in six months and reduced customer churn to less than one percent. Product Details Oracle Communications Data Model provides industry-specific schema and embedded analytics that address key areas such as customer management, marketing segmentation, product development and network health. CSPs can efficiently capture and monitor critical data and transform it into actionable information to support development and delivery of next-generation services using: More than 1,300 industry-specific measurements and key performance indicators (KPIs) such as network reliability statistics, provisioning metrics and customer churn propensity. Embedded OLAP cubes for extremely fast dimensional analysis of business information. Embedded data mining models for sophisticated trending and predictive analysis. Support for multiple lines of business, such as cable, mobile, wireline and Internet, which can be easily extended to support future requirements. With Oracle Communications Data Model, CSPs can jump start the implementation of a communications data warehouse in line with communications-industry standards including the TM Forum Information Framework (SID), formerly known as the Shared Information Model. Oracle Communications Data Model is optimized for any Oracle Database 11g platform, including Oracle Exadata, which can improve call data record query performance by 10x or more. Supporting Quotes "Oracle Communications Data Model covers a wide range of business areas that are relevant to modern communications service providers and is a comprehensive solution - with its data model and pre-packaged templates including BI dashboards, KPIs, OLAP cubes and mining models. It helps us save a great deal of time in building and implementing a customized data warehouse and enables us to leverage the advanced analytics quickly and more effectively," said Yasuki Hayashi, executive manager, NTT Comware Corporation. "Data volumes will only continue to grow as communications service providers expand next-generation networks, deploy new services and adopt new business models. They will increasingly need efficient, reliable data warehouses to capture key insights on data such as customer value, network value and churn probability. With the Oracle Communications Data Model, Oracle has demonstrated its commitment to meeting these needs by delivering data warehouse tools designed to fill communications industry-specific needs," said Elisabeth Rainge, program director, Network Software, IDC. "The TM Forum Conformance Mark provides reassurance to customers seeking standards-based, and therefore, cost-effective and flexible solutions. TM Forum is extremely pleased to work with Oracle to certify its Oracle Communications Data Model solution. Upon successful completion, this certification will represent the broadest and most complete implementation of the TM Forum Information Framework to date, with more than 130 aggregate business entities," said Keith Willetts, chairman and chief executive officer, TM Forum.

I can see 2.6.27 2.6.28 2.6.29 2.6.30 2.6.31 2.6.32 2.6.33 2.6.34 2.6.35 2.6.36 2.6.37 2.6.38 2.6.39 below2.6.2 in the directory. Which version shall I pick up for installation? Readme file says, we have to do this to insert ztemt.ko in kernel.

• Oracle Introduces Oracle Communications Data Model to Provide Actionable Insight for Communications

  - by kimberly.billings

  To help communications service providers (CSPs) manage and analyze rapidly growing data volumes cost effectively, Oracle recently introduced the Oracle Communications Data Model (OCDM). With the OCDM, CSPs can achieve rapid time to value by quickly implementing a standards-based enterprise data warehouse that features communications industry-specific reporting, analytics and data mining. The combination of the OCDM, Oracle Exadata and the Oracle Business Intelligence (BI) Foundation represents the most comprehensive data warehouse and BI solution for the communications industry. Hong Kong Broadband Network, the fastest growing and second largest broadband service provider in Hong Kong, enhanced its data warehouse using Oracle Communications Data Model. It went live with OCDM within three months, and has increased its subscriber base by 37 percent in six months and reduced customer churn to less than one percent. Read more about HKBN's use of OCDM.

• Serial connection over a single USB cable (Windows to linux, or linux to linux)

  - by andyortlieb

  I'm helping out with a project for an embedded device that only has USB and no serial. This device is running Linux. These days, when we need to connect to a serial port on a device we typically use a USB to serial adapter (on something like a phone system or a load balancing device, etc). I would like to know if it is possible to have the host device behave as though it were a serial adapter, thus removing the need for one. Given the nature of USB, is this approach even necessary? To recap, I would like to be able to connect a single A-to-A USB cable from my workstation (be it windows or linux) to this device, for the purpose of administration (especially initial setup), using minicom, putty or hyperterminal. Thanks

• Windows with putty via USB serial cable to Linux serial port - output ok, input isn't

  - by Aharon Robbins

  I am trying to get two way serial communications going between a Windows XP system and a Linux system (RHEL 5). I have /sbin/agetty -L 9600 ttyS0 in /etc/inittab. I am using a generic USB to serial adaptor on Windows (Unitek) and a null modem cable. I have putty configured for 9600 baud, 8 bits, no parity, one stop bit, no flow control. I get the login prompt from agetty in the putty window but input does not work; I see weird characters in the putty screen. I can echo output into the device from windows and see it, but cat < /dev/ttyS0 just prints out weird characters from what I type. Any and all suggestions will be welcome. Thanks!

• Laptop with internal serial port in 2009 (and 2010)

  - by Vincent Demeester

  Are there any computer vendors (like Dell, Lenovo, or..) that still sell laptops with an internal serial port? We are using several modem and other kind of box at work that have to be used (and/or programmed) with serial port (RS232, DB9, ..). We tried many usb/pcmcia serial adapter which run fine when used to load programs on the boxes but not with modems. The protocol behind the RTC connection (with modem) need timer we are not able to reach when using an adapter (maybe until we find a very good adapter), and that leads to my question..

• Reading a Serial Port - Ignore portion of data written to serial port for certain time

  - by farmerjoe

  I would like to read data coming and Arduino on a serial port on intervals. So essentially something like Take a reading Wait Take a reading Wait Take ... etc. The problem I am facing is that the port will buffer its information so as soon as I call a wait function the data on the serial port will start buffering. Once the wait function finishes I try and read the data again but I am reading from the beginning of the buffer and the data is not current anymore, but instead is the reading taken at roughly the time the wait function began. My question is whether there is a way that I am unaware of to ignore the portion of data read in during that wait period and only read what is currently being delivered on the serial port? I have this something analogous to this so far: import serial s = serial.Serial(path_to_my_serial_port,9600) while True: print s.readline() time.sleep(.5) For explanation purposes I have the Arduino outputting the time since it began its loop. By the python code, the time of each call should be a half second apart. By the serial output the time is incrementing in less than a millisecond. These values do not change regardless of the sleep timing. Sample output: 504 504 504 504 505 505 505 ... As an idea of my end goal, I would like to measure the value of the port, wait a time delay, see what the value is then, wait again, see what the value is then, wait again. I am currently using Python for this but am open to other languages.

• Serial port game controller (racing pedals)

  - by Cheesegraterr

  I have an old madCatz racing wheel for the playstation 2. The gas and brake pedals are connected to the wheel by a serial port. I just bought a usb racing wheel for the PC but it lacks pedals so I wanted to see if I could get these old madCatz working. I just installed the serial port in my motherboard, but now I have a problem with software. Nothing will recognize the pedal. I was wondering if there are any programs or drivers out there that will allow me to set the pedals up to work. Any advice would be appreciated!

• Detecting/Reactivating serial port that becomes inactive on Ubuntu Linux 10.10

  - by Tom

  I am using a usb2serial port to communicate with some old equipment (using my code built upon the boost asio library - I think my code is fine because it works almost all of the time). Every so often (maybe once every few days) the communication stops with my device with no error at all - the device just does not respond. I then restart my computer and everything is fine again. Does anyone know where I can start to analyse this problem? My serial port loads up fine (in /dev/ttyUSB0) and the boost library does not throw an error. The device just does not respond. If I restart the device no change - only when I restart my pc does it make a difference. I have also tried unplugging and replugging the usb connector. Does anyone know what gets cleared in the reboot (w.r.t the serial device) or what I can probe when the problem happens again (rather than just restarting with hope)

• Multi serial devices on one port

  - by adopilot

  I am developing one software for managing parking lot. System is designed to use four HID RFID devices for authorization clients on gates. Each device should be connected to server by Serial port RS232. Now I wondering is there some device or method to join all that devices on one device and after that to I have only one RS232 cable connected to server. My problem is in that RFID card readers are simple (stupid) devices and there I am not able to change anything, but Ill like to know from which specific device is coming input. What Ill want to do with that new device which need to join four readers is to add suffix or prefix to string that sent from RFID card reader. So I can identify device that is sending card number to my server. I am developing my system on Win platforms.

• Ubuntu Server 12 not spawning a serial ttyS0 when running on Xen

  - by segfaultreloaded

  I have this problem on more than one host, so the specific hardware is not an issue. Bare metal Ubuntu 12 is not creating a login process on the only serial port, in the default configuration. The serial port works correctly with the firmware. It works correctly with Grub2. I have even connected the serial line to 2 different external client boxes, so the problem is neither the hardware nor the remote client.

• java serial I/O: handling USB serial connection/disconnection in a robust manner

  - by Jason S

  I'm using rxtx for serial I/O handling in Java with an FTDI2232H that provides a USB comm port. It works great, with one exception: if I unplug the USB cable, so that the COM port disappears at runtime, it spews exceptions left and right: java.io.IOException: No error in nativeavailable at gnu.io.RXTXPort.nativeavailable(Native Method) at gnu.io.RXTXPort$SerialInputStream.read(RXTXPort.java:1427) at gnu.io.RXTXPort$SerialInputStream.read(RXTXPort.java:1339) and when I re-plug the cable in again, it does not recover. Is there any way to get rxtx to work properly with USB comm port connection/disconnection? (I've tried to post to the rxtx mailing list but for some strange reason I cannot send messages even though I am subscribed to the list. I've emailed the list admin and have gotten no response.) If not, is there another serial I/O framework that does?

• How do I get OBDII software working?

  - by NoBugs

  I have an ODBII USB cable for vehicle diagnostics, unfortunately I haven't been able to get it working on Ubuntu 12.04. The closest I've come is using the VAG-COM software with wine, using the ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1 trick and running stty -F /dev/ttyUSB0 speed 9600 repeatedly. It will connect and show the vehicle is OBDII, but none of the useful features seem to be working. I tried: Scantool - says it's connecting to the /dev/device in terminal, but doesn't. obdgpslogger - times out all the time. pyobd - This seems to be the most up-to-date source I could find, I had to adjust the code a bit to work (see here for changes). Still, in obd_io.py interpret_result function, it says it's looking for 4 space separated numbers, where the usb-serial is receiving bogus code "0100" instead? The device shows up in lsusb as: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Is the problem that these native tools don't expect a USB serial, or a serial of this type? Or are these apps too old to recognize OBD2 of this vehicle?

• Changing permissions on serial port

  - by Terrik

  I'm using the Arduino IDE in Ubuntu, and am having issues with the serial port. It has worked in the past, but for reasons that may be unnecesary, I felt the need to change the ownership of some of the files from root ownership to my users ownership. This made the IDE work correctly, but I lost the ability to use the correct serial port. In the dev folder, the port I need is listed as permission 166. Someone (who is no longer in the area to help me) swapped the permissions to 666, which made it all work gloriously. However, it reverted back as soon as I restarted my computer, and if I now try to use the command: sudo chmod 666 ttyACM0 nothing happens. No error messages, but no permission change either. How can I change it, and how can I get it to change permanently. I apologize if this question is overly simplistic or unclear, I'm an ubuntu noob, and I wouldn't begrudge feedback!

  I've mentioned OCDM in previous posts but found the following (see end of the post) podcast on the topic and figured it is worthwhile to spread the news some more. ORetailDM and OCommunicationsDM are the two data models currently available from Oracle. Both are intended to capture: Business best practices and industry knowledge Pre-built advanced analytics intended to predict future events before they happen (like the Churn model shown below) Oracle technology best practices to ensure optimal performance of the model All of this typically comes with a reduced time to implementation, or as the marketing slogan goes, reduced time to value.

• Linux: How to find all serial devices (ttyS, ttyUSB, ..) without opening them?

  - by Thomas Tempelmann

  What is the proper way to get a list of all available serial ports/devices on a Linux system? In other words, when I iterate over all devices in /dev/, how do I tell which ones are serial ports in the classic way, i.e. those usually supporting baud rates and RTS/CTS flow control? The solution would be coded in C. I ask because I am using a 3rd party library that does this clearly wrong: It appears to only iterate over /dev/ttyS*. The problem is that there are, for instance, serial ports over USB (provided by USB-RS232 adapters), and those are listed under /dev/ttyUSB*. And reading the Serial-HOWTO at Linux.org, I get the idea that there'll be other name spaces as well, as time comes. So I need to find the official way to detect serial devices. Problem is that there appears none documented, or I can't find it. I imagine one way would be to open all files from /dev/tty* and call a specific ioctl() on them that is only available on serial devices. Would that be a good solution, though? Update hrickards suggested to look at the source for "setserial". Its code does exactly what I had in mind: First, it opens a device with: fd = open (path, O_RDWR | O_NONBLOCK) Then it invokes: ioctl (fd, TIOCGSERIAL, &serinfo) If that call returns no error, then it's a serial dev, apparently. I found similar code here, which suggested to also add the O_NOCTTY option. There is one problem with this approach, though: When I tested this code on BSD Unix (i.e. OSX), it worked as well, however serial devices that are provided thru Bluetooth cause the system (driver) to try to connect to the bluetooth device, which takes a while before it'll return with a timeout error. This is caused by just opening the device. And I can imagine that similar things can happen on Linux as well - ideally, I should not need to open the device to figure out its type. I wonder if there's also a way to invoke ioctl functions without an open, or open a device in a way that it does not cause connections to be made? Any ideas?

• Linux: How to find all serial devices (ttyS, ttyUSB and others)?

  - by Thomas Tempelmann

  What is the proper way to get a list of all available serial ports/devices on a Linux system? In other words, when I iterate over all devices in /dev/, how do I tell which ones are serial ports in the classic way, i.e. those usually supporting baud rates and RTS/CTS flow control? The solution would be coded in C. I ask because I am using a 3rd party library that does this clearly wrong: It appears to only iterate over /dev/ttyS*. The problem is that there are, for instance, serial ports over USB (provided by USB-RS232 adapters), and those are listed under /dev/ttyUSB*. And reading the Serial-HOWTO at Linux.org, I get the idea that there'll be other name spaces as well, as time comes. So I need to find the official way to detect serial devices. Problem is that there appears none documented, or I can't find it. I imagine one way would be to open all files from /dev/tty* and call a specific ioctl() on them that is only available on serial devices. Would that be a good solution, though?

• Fedora14 serial console how-to needed

  - by lamba2

  Has anyone ever got a serial console working in fedora 14 ? Is it as simple as adding to grub: serial --unit=0 --speed=38400 terminal --timeout=10 serial console and add to the kernel lines: console=tty0 console=ttyS0,38400 ??? If so, this isn't working for me. I have agetty installed, and im using minicom, although i've heard you can also use "screen /dev/ttyUSB0" on the client side. The /etc/init/serial.conf file suggests it should be working, but nothing. Currently getting no joy from any of this after 2 days. Does anyone know a method that definitely works on fedora 14 ? (no /etc/event.d/ needed or such) edit: Client side im using a null modem cable and usb-serial adaptor.
