  • TechEd 2014 Day 4

    - by John Paul Cook
    Many people visiting the SQL Server booth wanted to know how to improve performance. With so much attention being given to COLUMNSTORE and in-memory tables and stored procedures, it is easy to overlook how important tempdb is to performance. Speeding up tempdb I/O improves performance. The best way to do this is to not do the I/O in the first place. With SQL Server 2014, tempdb page management is smarter. Pages are more likely to be released before being unnecessarily flushed to disk. Read more about...(read more)

  • &quot;The protocol 'net.msmq' is not supported.&quot;

    - by John Breakwell
    The “Lessons Learned” blog has an update covering the error message "The protocol 'net.msmq' is not supported." "The protocol 'net.msmq' is not supported." OMG, a new lesson! Will wonders never cease? So I ran into an interesting issue setting up a WCF service to consume an MSMQ queue. I won't bother you with the details of how to actually build a WCF/MSMQ service; there are plenty of tutorials on the subject. I want to share with you an interesting error that I ran into and the surprisingly simple fix. The error occurs when attempting to generate a Service Reference or even simply browsing to the WSDL of your WCF/MSMQ service in the form of a YSOD with the following error: "The protocol 'net.msmq' is not supported." After a lot of Googling on the subject turning up plenty of questions with the same error but no answers. So I went digging into some application level config files on a server that already had a WCF/MSMQ service successfully set up by the network admin, and the answer was amazingly simple: If you are hosting an MSMQ/WCF service in IIS, you have to tell IIS to allow net.msmq protocol. It's in the advanced settings for the application or site in which you are hosting the service. .... aaaand, that's it.

  • Setting up a transparent proxy with only one box.

    - by Scott Chamberlain
    I am playing around with transparent proxies, unfortunately I do not have two machines to test it out with. The current way I am doing things is the program makes a request to a computer on port 80, I use iptables -t nat -A OUTPUT -p tcp --destination-port 80 -j REDIRECT --to-port 1234 to redirect to my proxy that I am playing with. the proxy will send out a request to port 81 (as all outbound port 80 are being fed back in to the proxy so I want to do something like iptables -t nat -A OUTPUT -p tcp --destination-port 81 -j DNAT --to-destination xxxx:80 The problem lies with the xxxx part. How do I change the destination port without changing changing the destination ip? Or am I doing this setup completely wrong, I am learning after all and constructive criticism is definitely appreciated. The machine I am using is pretty low end so I would like not not have to create a VM with a second box unless absolutely necessary.

  • Upgrading to 9.2 - Info You Can Use (part 2 - Get Hands On Experience)

    - by John Webb
    Our guest blogger, Rebekah Jackson, continues with a series of helpful hints on planning your upgrade to PeopleSoft 9.2. Get Hands-On Experience With a an Easy to Install Demo Image Once you have identified the features you believe can add value (see part 1 of this series here), we recommend that you use our Demo Images to quickly create a PeopleSoft environment where you can try out the new features. The Demo Images are virtual machines that run in VirtualBox.   They contain a fully functioning PeopleSoft environment, including the database, PeopleTools, and the application.  These images can be loaded onto nearly any sized machine that meets the specs outlined in the documentation, including a powerful desktop machine.     The image allows you to very quickly deploy a fully functioning PeopleSoft instance that you can use to explore new features and functions or run a conference room pilot. To take advantage these Demo Images: Go to the Demo Images Home Page (Doc id 1552548.1) on My Oracle Support. Use the " Demo Image Quick Start Guide" and additional documentation links on that page to download and install your desired Demo Image. New Demo Images are posted for each product area approximately every 10 weeks, available shortly after the corresponding patching image. When installed, use the Demo Image to explore the desired features and capabilities. Important Notes: - It is not required to use the Demo Images to evaluate features and functions – any 9.2 instance will support this. We recommend use of the Demo Images because the setup and configuration is dramatically faster than doing a traditional PeopleSoft install. - For those looking to explore new features and capabilities on PeopleSoft 9.1 releases, we have provided virtual machine images using the Oracle Virtual Machine technology. Details and links are available in Oracle’s PeopleSoft Virtualization Products page (Doc id 1538142.1). /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman";}

  • Upgrading to 9.2 - Info You Can Use (part 1)

    - by John Webb
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Rebekah Jackson joins our blog with a series of helpful hints on planning your upgrade to PeopleSoft 9.2.   Find Features & Capabilities There are many ways that you might learn about new features and capabilities within our releases, but if you aren’t sure where to start or how best to go about it, we recommend: Go to www.peoplesoftinfo.com Select the product line you are interested in, and go to the ‘Release Content’ tab Use the Video Feature Overviews (VFOs) on YouTube and the Cumulative Feature Overview (CFO) tool to find features and functions. The VFOs are brief recordings that summarize some of our most popular capabilities. These recordings are great tools for learning about new features, or helping others to visualize the value they can bring to your organization. The VFOs focus on some of our highest value and most compelling new capabilities. We also provide summarized ‘Why Upgrade to 9.2’ VFOs for HCM, Financials, and Supply Chain. The CFO is a spreadsheet based tool that allows you to select the release you are currently on, and compare it to the new release. It will return the list of all new features and capabilities, by product. You can browse the full list and / or highlight areas that look particularly interesting. Once you have a list of features by product, use the Release Value Proposition, Pre-Release Notes, and the Release Notes documents to get more details on and supporting value statements about why those features will be helpful. Gather additional data and supporting information, including: Go to the Product Data Sheets tab, and review the respective data sheets. These summarize the capabilities in the product, and provide succinct value statements for the product and capabilities. The PeopleSoft 9.2 Upgrade page, which has many helpful resources. Important Notes:   -  We recommend that you go through the above steps for the application areas of interest, as well as for PeopleTools. There are many areas in PeopleTools 8.53 and the 9.2 application releases that combine technical and functional capabilities to deliver transformative value.    - We also recommend that you review the Portal Solutions content. With your license to PeopleSoft applications, you have access to many of the most powerful capabilities within the Interaction Hub.    -  If you have recently upgraded to PeopleSoft 9.1, and an immediate upgrade to 9.2 is simply not realistic, you can apply the same approaches described here to find untapped capabilities in your current products. Many of the features in 9.2 were delivered first in our 9.1 Feature Packs. To find the Release Value Proposition, Pre-Release Notes, and Release Notes for these releases, search on ‘PeopleSoft 9.1 Documentation Home Page’ on My Oracle Support, and select your desired product area. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman";}

  • Is it OK to mix C and C++ in an interview?

    - by John Pell
    If I am asked in an interview to write down some code, should I completely stick with C++ or is it acceptable to "mix" the two to write easy code as it comes to my mind? I'll explain it: if I'm asked to create a "stack" data type, a C++ class is perfectly suited, while if I need to parse some strings a strtok/sscanf is far easier than STL. On the other hand, if I need a generic container STL and templates are the way to go. Everything can be done in C or in C++, but in an interview I can't code everything or remember every standard/STL function. What is an acceptable tradeoff?

  • How do you completely reset monitor configuration (e.g. what used to be dpkg-reconfigure xserver-xorg)?

    - by John
    Using unity 11.04. I have a secondary monitor (actually two, one at home, one at work). The home twin monitor set up works perfect (Viewsonic monitor). At work, I get very buggy behaviour, such as full screen applications 'ghosting' when maximized, and other strange effects. I would like to try and completely reset the monitor configurations (not unity or compiz), before doing anything else. In 10.10 this would be accomplished: dpkg-reconfigure xserver-xorg

  • PLEASE HELP! Cannot login to server after file permissions change!

    - by John
    So, I did something really stupid. Please bear with me as I am new to ubuntu server. I ran chmod -R 700 / when I was logged in as root. Now when I try to login as my normal user I immediately get kicked out. Is there anyway to log back in to the server whether it is root or whoever so that I can change the permissions? or am I totally screwed? I dont think I have root access enabled in the /etc/ssh/sshd_config file. I do have physical access to the server. I really need some help here. Thanks in advance!

  • What Do I Need To Know About Servers In a Web Development Role?

    - by john
    I know that may sound a little vague, so I'll try and explain a little further... After being self employed developer for many years I'm now in search of a commercial web developer role. My only experience with servers and hosting is uploading through FTP and playing around with CPanel/WHM a little. The role's I'm going for are web development PHP, MySQL, HTML, CSS type roles, but in recent interviews I've been asked questions about setting up things on the server, that I had no idea what was being said... which wasn't ideal! Without knowing more than I do, it's hard to explain what exactly I'm looking to learn, but it's basically just the server elements I should know as a web developer? If you're a web developer, do you have any dealing with the server apart from uploading files, and if so, what? Are things like Subversion(SVN) and version control systems often set up by the web development team, could that be what they were talking about?

  • SSL on app - nginx web server

    - by Adam
    I am running an nginx web server where I redirect all http requests to https (with a self signed cert). Here is how I REDIRECT all http requests to https in the nginx config file: server { listen 80 default_server; listen [::]:80 default_server ipv6only=on; server_name my.server.ip; return 301 https://$server_name$request_uri; Problem is - I cannot seem to do so for an app running on a port. Example: http://my.server.ip:1234 does not redirect to https://my.server.ip:1234 ir works fine on all other urls like http://my.server.ip/temp etc. How can I modify the nginx config file to force that app url through ssl?

  • Need suggestions on what you regard as &ldquo;security&rdquo;

    - by John Breakwell
    I’m currently writing a large piece on MSMQ security and wanted to check I was covering the right areas. I have some doubts as I’ve seen the occasional MSMQ forum question where a poster has used the word “security” in different contexts to what I was expecting. So here are the areas I plan to cover: Message security encryption on the wire (SSL and IPSEC) encryption of the message (MSMQ encryption) encryption of the payload (data encryption) signing and authentication Queue security SIDs and ACLs Discoverability Cross-forest issues Storage security NTFS permissions unencrypted data Service security Ports and Firewalls DOS attacks Hardened mode (HTTP only) RPC secure channel requirement authenticated RPC requirement Active Directory object permissions Setup Administrator requirements What else would you want to see?

  • VLC stream with trickplay

    - by marjasin
    The idea is to start a video stream from one computer and watch it on another with the ability to start/stop the stream. I think I could do this with VLC but i haven't been able to figure out how. I've tried the following: (From the official forum) Stream with RTSP and RTP: on the server, run: % vlc -vvv input_stream --sout '#rtp{dst=192.168.0.12,port=1234,sdp=rtsp://server.example.org:8080/test.sdp}' on the client(s), run: % vlc rtsp://server.example.org:8080/test.sdp But this doesn't give me the ability to start/stop the stream from the client. According to the VLC release note something called "Trick play" was added in version 1.0. This seems to be what I'm looking for but i can't find any documentation that descibes how to use it.

  • Should I keep separate client codebases and databases for a software-as-a-service application?

    - by John
    My question is about the architecture of my application. I have a Rails application where companies can administrate all things related to their clients. Companies would buy a subscription and their users can access the application online. Hopefully I will get multiple companies subscribing to my application/service. What should I do with my code and database? Seperate app code base and database per company One app code base but seperate database per company One app code base and one database The decision involves security (e.g. a user from company X should not see any data from company Y) performance (let's suppose it becomes successful, it should have a good performance) and scalability (again, if successful, it should have a good performance but also easy for me to handle all the companies, code changes, etc). For the sake of maintainability, I tend to opt for the one code base, but for the database I really don't know. What do you think is the best option?

  • How to view files backed up to Ubuntu One by Déjà Dup?

    - by irrational John
    I decided to try out the Ubuntu Backup system application on my 11.10 partition. Currently I am just using the default settings to back up folders in my Home (~) folder to the deja-dup in my Ubuntu One cloud. I have not been able to figure out how to view which files have been saved to the backup location other than by restoring them to a temp folder and then seeing what was restored. I'm hoping there is a less kludgy way to just find out what has or has not been backed up.

    The AdventureWorks2014 sample database is downloadable from here . If you choose to run the script and are unfamiliar with sqlcmd, this post shows you what to do. Be sure to extract the zip file’s contents to a new folder because the instawdb.sql comes with 72 csv files that contain the actual data. If you specify a folder other than the default, you’ll have to change a path in the instawdb.sql script to point to your directory. Figure 1. instawdb.sql script file in SSMS.

  • What amount of PHP memory usage is reasonable for multiple WordPress sites? [closed]

    - by John
    It seems like I've been plagued with memory usage issues most of the time I've been blogging (7 years). I upgraded my hosting to a HostGator VPS and still seem to have issues. I have about a dozen WP 3.4.2 sites running within a single account. Each has a separate installation. I finally installed TPC! Memory Usage within one of my WP installs to see what was going on. The memory usage just standing still is on the order of 40 MB. This seems high, but I don't know. What would be a reasonable memory usage for these WP installs? Do I need to take other things into account, or am I even looking at it the right way?

Any help would be appreciated.

  • What could a kernel mode driver be possibly useful to?

    - by John Pell
    This might sound weird but there's an explanation for my question: I want to write something to impress a potential recruiter, and I want (to strenghten my skills) to create a program which should communicate with kernel mode driver(s). I'm not starting from a goal and trying to design the system to achieve it, I'm doing the opposite: designing the system and trying to justify it with a meaningful goal. So here comes the question: what could a kernel mode driver be possibly useful to? The answers that come to my mind right now are: I might want to communicate with hardware (not really my case, it's a software project mainly) I might want to mess around with the OS (security/hooking?) ?? I need some other examples like those

  • How do I force the system to look for new sound devices?

    - by John Zeringue
    I have a small flat screen TV (Toshiba) that I often connect via HDMI to my laptop (an HP Pavilion dv4) and use as a computer monitor. When I do this, I prefer to use the TV's speakers, particularly when I'm watching video, because the sound quality is much better. However, when I connect the HDMI cable after turning on my computer (rather than having it plugged in before booting up), Sound Settings does not list the TV as an output device, and I am forced to reboot. I was curious if there is an easier solution to this, perhaps a CLI command to check for new sound outputs. Does anyone know of something like this or have another solution? To clarify, I believe this is a software problem. The HDMI always works, and I can switch my desktop over to the TV at any time. The issue is that, if the HDMI wasn't connected during start up, the TV will not appear as an output option in the Sound Settings GUI. So, unless I'm mistaken, my question is not HDMI specific, but rather a general usage question about manipulating sound settings from the command line.
