• MySQL query works in Workbench but gives error code 63 from PHP

  - by smund3

  I am making a poll system with PHP/MySQL and have made created a MySQL user for the system to use. However, whenever I try to run a query from PHP as that user, I get error code 63, which after some Googleing I found out means: OS error code 63: Out of streams resources If I make the PHP script use an almighty user instead, everything works fine, so it looks like it has something to do with permissions. I am using a non-persistent connection. I have Googled a lot but I haven't found anything even slightly relevant to this issue. What could cause this error? EDIT: Now it actually started giving me a different error: OS error code 65: Package not installed ...all I did was revert the script to using the poll user instead of the almighty one.

• E-Business Suite : Role of CHUNK_SIZE in Oracle Payroll

  - by Giri Mandalika

  Different batch processes in Oracle Payroll flow have the ability to spawn multiple child processes (or threads) to complete the work in hand. The number of child processes to fork is controlled by the THREADS parameter in APPS.PAY_ACTION_PARAMETERS view. THREADS parameter The default value for THREADS parameter is 1, which is fine for a single-processor system but not optimal for the modern multi-core multi-processor systems. Setting the THREADS parameter to a value equal to or less than the total number of [virtual] processors available on the system may improve the performance of payroll processing. However on the down side, since multiple child processes operate against the same set of payroll tables in HR schema, database may experience undesired consequences such as buffer busy waits and index contention, which results in giving up some of the gains achieved by using multiple child processes/threads to process the work. Couple of other action parameters, CHUNK_SIZE and CHUNK_SHUFFLE, help alleviate the database contention. eg., Set a value for THREADS parameter as shown below. CONNECT APPS/APPS_PASSWORD UPDATE PAY_ACTION_PARAMETERS SET PARAMETER_VALUE = DESIRED_VALUE WHERE PARAMETER_NAME = 'THREADS'; COMMIT; (I am not aware of any maximum value for THREADS parameter) CHUNK_SIZE parameter The size of each commit unit for the batch process is controlled by the CHUNK_SIZE action parameter. In other words, chunking is the act of splitting the assignment actions into commit groups of desired size represented by the CHUNK_SIZE parameter. The default value is 20, and each thread processes one chunk at a time -- which means each child process inserts or processes 20 assignment actions at any time. When multiple threads are configured, each thread picks up a chunk to process, completes the assignment actions and then picks up another chunk. This is repeated until all the chunks are exhausted. It is possible to use different chunk sizes in different batch processes. During the initial phase of processing, CHUNK_SIZE number of assignment actions are inserted into relevant table(s). When multiple child processes are inserting data at the same time into the same set of tables, as explained earlier, database may experience contention. The default value of 20 is mostly optimal in such a case. Experiment with different values for the initial phase by +/-10 for CHUNK_SIZE parameter and observe the performance impact. A larger value may make sense during the main processing phase. Again experimentation is the key in finding the suitable value for your environment. Start with a large value such as 2000 for the chunk size, then increment or decrement the size by 500 at a time until an optimal value is found. eg., Set a value for CHUNK_SIZE parameter as shown below. CONNECT APPS/APPS_PASSWORD UPDATE PAY_ACTION_PARAMETERS SET PARAMETER_VALUE = DESIRED_VALUE WHERE PARAMETER_NAME = 'CHUNK_SIZE'; COMMIT; CHUNK_SIZE action parameter accepts a value that is as low as 1 or as high as 16000. CHUNK SHUFFLE parameter By default, chunks of assignment actions are processed sequentially by all threads - which may not be a good thing especially given that all child processes/threads performing similar actions against the same set of tables almost at the same time. By saying not a good thing, I mean to say that the default behavior leads to contention in the database (in data blocks, for example). It is possible to relieve some of that database contention by randomizing the processing order of chunks of assignment actions. This behavior is controlled by the CHUNK SHUFFLE action parameter. Chunk processing is not randomized unless explicitly configured. eg., Set chunk shuffling as shown below. CONNECT APPS/APPS_PASSWORD UPDATE PAY_ACTION_PARAMETERS SET PARAMETER_VALUE = 'Y' WHERE PARAMETER_NAME = 'CHUNK SHUFFLE'; COMMIT; Finally I recommend checking the following document out for additional details and additional pay action tunable parameters that may speed up the processing of Oracle Payroll.     My Oracle Support Doc ID: 226987.1 Oracle 11i & R12 Human Resources (HRMS) & Benefits (BEN) Tuning & System Health Checks Also experiment with different combinations of parameters and values until the right set of action parameters and values are found for your deployment.

• Ubuntu 12.04 LXC nat prerouting not working

• How to port forward https traffic via ssh and/or remote desktop to through several networks and PCs?

  - by donttellya

  I have the following environment: In company X I develop a application on a pc A in network A with ip address 192.168.100.50 which has to do an https request to an http server located in the intranet of company Y In company X is another pc B in network B with ip address 192.168.200.100 pc B (of company X) can access the intranet from company Y via ssh tunnel (putty) pc A (of company X) can ping pc B (of company X) note: pc A can also do a remote desktop connection to pc B) pc B can ping the http sever pc A can not ping the http server How can the https request from pc A of company X get to the http server of company Y? On which pc must be putty configured? And which settings for host, port forwarding etc. has to be done in putty? So finally the https request should go from PC A - PC B - Http Server in company Y.

• Is it possible to add tcp autotuning to windows xp?

  - by Caspin

  I have a network application that needs to send messages at 60 times a second. The messages are usually 300-400 bytes, but can be as large as 1500. The default setting for SO_SNDBUF is too small and limits the number of message that can be sent if the network latency is anything greater then 100ms. The naive solution is to just bump the SO_SNDBUF size to to something large. However, depending on the latency and the packet size that could be anywhere from 64K to 8MB. One of Vista's new features is TCP autotuning. Autotuning monitors the tcp connection and dynamically adjust the buffer sizes to allow for optimal communication. I would like to use auto tuning on our windows xp machine so I don't need to guess what my buffers sizes should be. Is there a way to install either a microsoft or 3rd party tcp autotuner on windows xp?

• How do I establish the network sharing to my WinXP server network drive from my Mac notebook?

  - by mobibob

  I have been able to connect to my WinXP server's shared drives by using Finder's Command-K to browse the network. Unfortunately, when the server gets rebooted, the connection drops and sometimes I cannot get reconnected. I have specified different protocols (afp / cifs / smb) and different login names (connect as...) with limited success. Once I find the right combination, I am good for a few weeks. Once, it seems as though I had to unshared and shared the drive to get it to work. Unfortunately, it is very frustrating, so I try multiple things at one time, so when I finally get to the success point -- I honestly don't know what worked. I followed Mac help, surfed for instructions, issues, etc., but nothing appears to be consistent. I would love for this thread to be the ultimate answer for all time! Can anyone help me? If my description or question need more detail, please ask away!

• Apache does not serve non-locally

  - by yodaj007

  I have a freshly installed instance of Fedora Core 16 inside VirtualBox using bridged networking. On it, as root I typed in: yum -y install httpd service httpd start ifconfig Inside the VM, I can open a web browser to 'localhost' and I get the Apache test page. It works. But in Windows (the machine hosting the VM), I point my browser to the IP address returned by ifconfig (192.168.2.122). The connection times out. I can go to a command prompt and ping the VM. Is there a firewall or something that comes with Fedora by default? Or is there something I need to change in a config file?

• Best way to split LAN computers on two WANs (not load balancing)

  - by lpfavreau

  What is the best way to split the computers of a LAN (about 50 computers) to go on two WANs, depending on the computers' IP address or computers' configuration (gateway). I'm not looking for load-balancing, I need to be able to route which computer uses which Internet connection. A solution would be to rewire the old office to split the two distinct groups that need to use two different Internet connections but I'm not sure it's worth it at the moment. I have a pfSense router configured with the LAN (DHCP), WAN1 and WAN2. I also have the IP addresses (and ability to configure) the next router on WAN1 and the one on WAN2. What would you suggest? Routing based on IP addresses ranges? Different gateways? VLANs would be difficult for the same reason as to why rewire is a bit complicated. Thanks!

• DSL-504T as dumb ADSL modem

  - by petebob796

  I am trying to setup an existing DSL-504T ADSL router to work as a dumb modem for a DIR-825 wifi router. I am assuming I should try and move as much of the control to the DIR-825 as possible. It's a PPPoA connection so I don't think I can use bridge mode. Does anyone have any guidance on this? Should I have 2 subnets? Should I set the DIR-825 as the DMZ on the DSL-504T? Do I need to keep NAT and firewall enabled on DSL-504T? Basically I have it working but want to know if I have set it up correctly as I really want the QoS to work on the DIR-825.

• Disconnected from WiFi, Windows claims otherwise [closed]

  - by Manu

  I'm connected via wifi to my ISP's router/modem. While Windows says that I'm always connected, I keep getting messages from Netgear Genie that I've lost contact to the Internet, and I cannot access webpages until it comes back. There are two other computers in the house, one connected to the router via ethernet, the other via wifi, both seem to have no such problems. I've wondered if Netgear genie itself was the problem, but I am regularly disconnected even if I uninstall it. And I'd rather have it since it accurently tells me if I'm connected or not. Why does windows says I'm online if I can't access any online game, or website ? I've removed the connection, recreated it, I've even copied the settings to a usb key from the computer that has wifi access. Is there a tool that can tell me which program, if any, is disconecting me ?

• Bluetooth not working on Acer 3820tg (Ubuntu 12.04)

  - by Iohannes

  After upgrading to 12.04 (it was done by a complete reinstallation), bluetooth doesn't work anymore. Before (I think it was Ubuntu 11.04), I just followed instructions on this page and copied /lib/firmware/ath3k-2.fw to /lib/firmware/ath3k-1.fw and everything was fine. But in 12.04, there isn't any ath3k-2.fw in the /lib directory, so this method is not possible. Also, pressing Fn+F3 doesn't work. I would appreciate any help.

• Can a switch consume bandwidth?

  - by aashiq

  I have a network with a router and a switch. At first my ISP's optical fiber is connected with media converter input port. Than Ethernet cable (output port of Media converter) is connected with the switch. Then an output Ethernet cable is connected with our inner Microtik router. Then this router is connected with another LAN switch. From this switch we have got every connection other switch. It is our total network structure. Our bandwidth is 2 Mbps. From the 11th of March our MRTG graph shows high all the time even when my all switch is switched off except LAN switch. That's why our line is breaking up (Voice call). How could be it possible? My all PC's bandwidth is limited but when connected PC with media converter directly then the graph shows normal. That's why I can't blame my ISP.

• Reporting available RDP sessions

  - by Sergei

  Hi All Default Windows 2003 Server has two RDP sessions available.If all of them are taken by someone else you will only be notified about it after providing your credentials. This seems like a waste of time especially in our environment where we share a lot of development server. Could a message be given as soon as you open the connection window if the connections are taken up? We can use qwinsta based script to check sessions before logon but it's still takes time. Is there a feature to do what I am asking for?

• Question on business connections and page rank?

  - by Viveta

  I just want to ask this question to get a yes no answer on something that I've been wondering on lately. So regarding how there are countless numbers of sites now that use the no-follow; making it harder to get ranking for your page if your website information might be something useful and will get traffic but maybe isn't something that your business connections share content of; but I am trying to find out if the benefit to having a bunch of say "likes" to your facebook page, but all the connection to your website's content isn't passing any benefit to your main page. So are you then competing with your own website in regards to SERPs to your facebook page and that of your home page. Am I correct on this; that if you start having your facebook page doing real good as far as connections and likes (helping bump up your facebook PageRank) but if you have links on your page with certain optimized keywords, that there is no benefit to your website (other than people getting to your facebook page, and then more likely to click to your page). Hope I explained it well what I am asking. Just wanted to get a better picture of this to know what I want to focus on as far as how I'll be linking to my desired landing pages in the future.

• ARTS Reference Model for Retail

  - by Sanjeev Sharma

  Consider a hypothetical scenario where you have been tasked to set up retail operations for a electronic goods or daily consumables or a luxury brand etc. It is very likely you will be faced with the following questions: What are the essential business capabilities that you must have in place?  What are the essential business activities under-pinning each of the business capabilities, identified in Step 1? What are the set of steps that you need to perform to execute each of the business activities, identified in Step 2? Answers to the above will drive your investments in software and hardware to enable the core retail operations. More importantly, the choices you make in responding to the above questions will several implications in the short-run and in the long-run. In the short-term, you will incur the time and cost of defining your technology requirements, procuring the software/hardware components and getting them up and running. In the long-term, as you grow in operations organically or through M&A, partnerships and franchiser business models  you will invariably need to make more technology investments to manage the greater complexity (scale and scope) of business operations.  "As new software applications, such as time & attendance, labor scheduling, and POS transactions, just to mention a few, are introduced into the store environment, it takes a disproportionate amount of time and effort to integrate them with existing store applications. These integration projects can add up to 50 percent to the time needed to implement a new software application and contribute significantly to the cost of the overall project, particularly if a systems integrator is called in. This has been the reality that all retailers have had to live with over the last two decades. The effect of the environment has not only been to increase costs, but also to limit retailers' ability to implement change and the speed with which they can do so." (excerpt taken from here) Now, one would think a lot of retailers would have already gone through the pain of finding answers to these questions, so why re-invent the wheel? Precisely so, a major effort began almost 17 years ago in the retail industry to make it less expensive and less difficult to deploy new technology in stores and at the retail enterprise level. This effort is called the Association for Retail Technology Standards (ARTS). Without standards such as those defined by ARTS, you would very likely end up experiencing the following: Increased Time and Cost due to resource wastage arising from re-inventing the wheel i.e. re-creating vanilla processes from scratch, and incurring, otherwise avoidable, mistakes and errors by ignoring experience of others Sub-optimal Process Efficiency due to narrow, isolated view of processes thereby ignoring process inter-dependencies i.e. optimizing parts but not the whole, and resulting in lack of transparency and inter-departmental finger-pointing Embracing ARTS standards as a blue-print for establishing or managing or streamlining your retail operations can benefit you in the following ways: Improved Time-to-Market from parity with industry best-practice processes e.g. ARTS, thus avoiding “reinventing the wheel” for common retail processes and focusing more on customizing processes for differentiations, and lowering integration complexity and risk with a standardized vocabulary for exchange between internal and external i.e. partner systems Lower Operating Costs by embracing the ARTS enterprise-wide process reference model for developing and streamlining retail operations holistically instead of a narrow, silo-ed view, and  procuring IT systems in compliance with ARTS thus avoiding IT budget marginalization While parity with industry standards such as ARTS business process model by itself does not create a differentiation, it does however provide a higher starting point for bridging the strategy-execution gap in setting up and improving retail operations.

• How do I require use of the 5 GHz band when connecting to a Wireless N access point?

  - by cqcallaw

  What is says in the topic: there's a Wireless N access point to which I'd like to connect using the 5 GHz band exclusively. How does one accomplish this? Using the directive band=a in the connection configuration file in /etc/NetworkManager/system-connections doesn't seem to affect anything (/var/log/syslog still shows attempts by wpa_supplicant to connect using the 2.4 GHz band), and running iwconfig wlan0 freq 5G per this question results in the following error: Error for wireless request "Set Frequency" (8B04) : SET failed on device wlan0 ; Invalid argument. [Edit] I'm hoping the answer won't depend on the hardware in use, but here's some information about the hardware, just in case: System is an Asus ZenBook Prime UX31A-DB51, running Ubuntu 12.04. lspci output: 00:00.0 Host bridge: Intel Corporation Ivy Bridge DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 00:04.0 Signal processing controller: Intel Corporation Device 0153 (rev 09) 00:14.0 USB controller: Intel Corporation Panther Point USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation Panther Point MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Panther Point High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 1 (rev c4) 00:1c.1 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 2 (rev c4) 00:1d.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Panther Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Panther Point 6 port SATA Controller [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation Panther Point SMBus Controller (rev 04) 00:1f.6 Signal processing controller: Intel Corporation Panther Point Thermal Management Controller (rev 04) 02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6235 (rev 24) The driver for the wireless interface is iwlwifi.

• Huwawei E220 broadband dongle not working

  - by Roshnal

  The problem is, I have used Ubuntu from 6.10 upto 11.10. And upto 11.04 I used my same USB 3G dongle to connect to broadband and it worked fine. But 2 days ago I upgraded to Ubuntu 11.10 and broadband is not working. It detects my dongle and creates a connection without a problem, but when connecting it just keeps on and on for a long time and then say I'm offline. So I did a clean install and the same thing occurred. But I also have a netbook and its got Ubuntu 11.10. I tried using the same dongle for internet on that netbook and it worked fine without any issues. But this isn't a problem with my USB port on my main machine or something like that because I'm also using Windows on my main machine (dual-boot) and its working fine. My hardware: Main computer (one that I'm trying to connect): 2.8GHz dual core Intel 2GB RAM 500GB Sata II HDD 384MB Video Memory (Intel G31/G33 chipset) Ubuntu 11.10 (32bit) My NetBook (broadband working fine): 1.6GHz Intel Atom (dual core) 1GB DDR3 RAM 250GB HDD 128MB Video Memory (Intel something-I-can't-remember) Ubuntu 11.10 (32bit) My dongle is a Huawei E220 and ISP is Dialog GSM (I'm in Sri Lanka) So any idea why this is? I really love Ubuntu and this is bugging me off.. Any help greatly appreciated. Regards, Roshnal

• linux shell, keep task alive for specified time

  Hello, I am looking for a tool to keep a task alive (restarting if necessary) for a specified amount of time (in seconds), and then kill it and stop. For example: keep_for 3600 rsync foo bar:faz should for try to synchronize a directory (restarting rsync in case of f.e. dropped connection), but explicitly kill rsync and stop respawning it after an hour. I tried to write a shell script for that, but it was surprisingly difficult to write, with lots of edge cases (like child process not getting killed, or shell escaping issues). So... maybe there already is a tool for that?

• How to show disconnect network drives

  - by Jake

  Windows 7 and Vista laptops in my company domain has network drives set up by Win2k8 Server GPO. Normally, when the laptops has ethernet cable plugged in before boot, the network drives connect and appear as expected at the end of startup sequence. However, when the laptop has ethernet cable unplugged, the network drives are not connected, which is fine, but the disconnected icons disappear as well. i.e. the drives are not set up. At the end of the startup sequence, upon reaching desktop, the wireless adapters will connect to the network and the laptop will be able to find the network drive. Hence I want the drives to be setup nonetheless, so that the next attempt to connect, say, via a desktop shortcut, will reestablish the network drive connection. How can this be done?

• Localized database for customers

  - by Jim

  The company I work for, has just moved to AWS - and currently they have one very large central database with the instance currently located in America. However, one of their clients has requested that all of their data is held in the EU. So creating an AWS instance in Ireland isn't a problem, the problem is the database and how to manage it. We were considering having another database that runs in the EU for European customers, and use a different primary key step, so that the primary keys will never conflict in case the two locations need to be merged in the future. The problem is, if we have a customer that uses our system in both America, and the EU we would have to create 2 accounts for that user, and reporting across both regions would not be possible as the connection time would be too high. Is there an alternative to set this up?

• How to get started setting up IP security cameras

  - by dave

  I have just finished renovating my house. As part of the job, I have cat6 cable run through the house, including two external plugs. All cables terminate in the same location. My rough plan is to plug two IP cameras to monitor the front and rear, run POE from a central router to the two external cameras, plug my PC into the same router and run magic software X. Any machine plugged into the router or wirelessly connection should then be able to get a live feed and alerts based on motion detection. That's the plan, but I'm not sure how possible it is. What hardware to get and what monitoring software to get. Has anyone does something similar? What were your experiences?

• mRemote and RoyalTS both are not able to RDP connect me to a Windows Server 2008 system?

  - by djangofan

  I am completely stuck on this one. If I start a RDP session independently of these 2 programs everything works fine. My RDP session connects, I click "OK" to accept the "Notice To Users" security message and then it shows me the login screen where I enter my password manually. Now, if I try to use either mRemote or RoyalTS to create this connection, I get the same behavior except that I get a "The user name or password is incorrect." message. Now, I know this cannot be true since I can manually connect with RDP. So, what is the problem with these 2 pieces of software that prevents me from logging in? I have no problems with connecting to Windows XP systems with these programs. Additionally, I wish I knew how to get one of these programs to automatically click the "OK" button on the "Notice To Users" message while automatically attempting to log me in as part of the login process. Can they do that?
