• Oracle 11g Data Guard over a WAN

  - by Dave LeJeune

  Hi - We are in process of looking at using Oracle's Data Guard to replicate our 11g instance from a colo facility in Washington DC to Chicago. To give some basics we have approximately 25TB of storage and a healthy transaction rate in the 1-2K/sec range. Also, because we are processing data in real-time we have a 24x7x365 requirement for processing data. We don't have any respites as far as volume except for system upgrades (once every few months) where we take the system offline but then course experience a spike in transactions when we bring the system back on-line. Ideally we would want the second instance in the DG configuration semi-online in a read-only fashion for reports/etc. We evaluated DG in 10g and were not overly impressed and research seemed to show that earlier versions had issues with replication over a WAN but I have heard good things about modifications the product has gone through w/ 11g. Can anyone confirm an instance of this size and transaction rate being replicated over a WAN and if so what is the general latency? An information or experiences with a DG implementation that is of this size and scope would really be helpful (or larger - I also realize we are still relatively small compared to many others out there). Many thanks in advance.

• Print each bookmark of a PDF separately

  - by Dave

  I have a very large (1000 page) PDF which contains about 100, ten page each documents one after the other. I would like to have them sent to my office printer as individual files so my office printer will print them double sided and staple each one individually. I'm using Adobe Acrobat X and think the first step is to bookmark the start of each of those 100 documents. I don't know the next step though. I also have a batch printing program so if i can extract each of those 100 bookmarks to individual files that would work too. Thanks for all the help.

• Seagate 1TB 'EXPANSION' external hard drive, showing as BAD

  - by Dave Plews

  Hello! I have bough an external Seagate 1TB drive, which my XP system can see and will write files to, however when I use Partition Magic it describes the whole partition as BAD, and it is shown in yellow. All the options are greyed out. When I use Drive Image XML to try and copy drive to drive (I want a comlplete copy of my C drive including OS), I get an error message saying it can't lock the drive. The external drive is brand new and uses NTFS. Any ideas? Seagate 'support' haven't bothered getting back to me. Incidentally, I have another external drive (320GB), which uses FAT32 and Partition Magic sees that fine. I am doing a full format of the Seagate at the moment, to see if this helps. Thanks in advance!

• Network not detected, but internet working

  - by Dave

  I am using a brand new HP computer with Windows 7 64 bit. When I first hooked it up it detected my network (hooked up through ethernet) easily. However, after I uninstalled Norton Internet Security, it stopped being able to detect my home network. I can still use the internet as if connected, but I can't go into the network options to communicate with other computers. I had this same problem on Windows Vista on my previous computer. Is there any way to fix this so it detects the network?

• How can I make an image appear partially in front and partially behind another layer in Adobe Illust

  - by Dave Forgac

  I'm using Adobe Illustrator CS4. I have a drawn vector image that is behind a layer with a stroked ellipse like this: However I need just one part of the image to appaer in front of the stroke. In this image I need the paw on the right to be in front of the stroke but I need the other leg to be covered by the stroke as it is above: I'm guessing I need to somehow make a copy of just the paw and place it on a layer above the layer with the stroke in order to achieve this effect however I don't know how to do that in Illustrator. Any help would be appreciated.

• Backing up to smaller drive

  - by Dave

  In a few hours I'll have a new 500GB Sony laptop, filled with the usual Sony rubbish which I'll promptly be replacing with Ubuntu or Crunchbang or something. However, first I want to make a full clone of the drive (including recovery partitions), should I wish to return it to Sony or sell it on in its factory state. The problem is that the only backup drives I have are less than 500GB - the biggest I have is 250GB or so! So I need to backup and compress on-the-fly. What's the best way to do this? Presumably dd piped into gzip would do the trick, or does anyone have any other suggestions to accomplish this?

• New mainboard for Shuttle

  - by Dave Arkell

  I have an old Shuttle barebones SN21G5 (AMD 64), and I really need a more modern chip in there. Is there a way of swapping out the old mainboard and putting in one of those new fangled phenom mainboards in there?

• Virtual Subdomains

  - by Dave P

  I would like to manage subdomains exclusively through .htaccess. I am able to catch subdomains that I set up - for example, support.testsite.com - currently, I redirect that to testsite.com/support. What I would like to do is retain the subdomain, even after the redirect - so support.testsite.com seems to stay in the address bar for the user, even though it is actually located at testsite.com/support. Should I maintain another .htaccess file in /support that rewrites the address? Thanks!

• Cross-platform centralized desktop password manager

  - by Dave

  I have been using KeePass as a desktop password manager on Windows for many years. Love it! However, I am now needing to work on different platforms much of my day (Windows 7, Windows XP, Mac OS X, Ubuntu, and OpenSUSE.) I'm looking for a password manager I can share across all these platforms. My ideal solution would: Run natively (not in a virtual machine) on all platforms. Store the "official" copy of the password data on a local network so I can get to it from any and all machines. It is OK if it locks (or becomes read-only) when one client is accessing it. Keep a local cached copy (read-only is fine) so I can still get to my passwords when disconnected from the network. Does any such beast exist?

• How do I find all text with particular background color?

  - by Dave M G

  I have a LibreOffice Writer document that has undergone a process of editing, and sections of the text that needed to be rewritten were highlighted in yellow. As I fixed those sections, I removed the yellow highlight. Now, I want to make sure there are no remaining areas of highlighted text that have not been fixed or possibly the highlight was not removed. It's many hundreds of pages, so a manual scan is unfeasible. Also, it might be that one space or one character got accidentally left highlighted, and I want to ensure I've accounted for them all. How can I search the document to find all instances where text has been highlighted?

• Create shortcut key to insert new row using Excel 2010

  - by Dave Jarvis

  Tried to create a macro in Excel to insert a row: Sub InsertRow() ' ' InsertRow Macro ' ' Keyboard Shortcut: Ctrl+Shift+I ' Selection.EntireRow.Insert End Sub However, this does not insert a new row without first manually selecting a row. Every solution I've found requires that a row be highlighted before inserting a new row. See also: http://www.shortcutworld.com/en/win/Excel_2010.html How would you create a shortcut key (e.g., Ctrl+Shift+J) to highlight the current row and insert a new row? Thank you! Update Looks like Shift+Space highlights the current row.

• How can I speed up a MySQL retore from a dump file?

  - by Dave Forgac

  I am restoring a 30GB database from a mysqldump file to an empty database on a new server. When running the SQL from the dump file, the restore starts very quickly and then starts to get slower and slower. Individual inserts are now taking 15+ seconds. The tables are MyISAM. The server has no other active connections. SHOW PROCESSLIST; only shows the insert from the restore (and the show processlist itself). Does anyone have any ideas what could be causing the dramatic slowdown? Are there any MySQL variables that I can change to speed the restore while it is progressing?

• Google Sites (via Apps) setup questions

  - by Dave

  I thought that it would be a piece of cake to set up a Google site via Google Apps, but perhaps my previous (limited) experience with web development has given me unrealistic expectations. I have actually had a really tough time finding help with the exact question that I have, which is: How do I change the home page contents??? You see, I'm used to having hosting with someone like GoDaddy, where I can just ftp in and drop my HTML files in the www folder. From research I have found that this is simply not possible with any flavor of Google Sites. That's fine, I can live with it. So let's say I have www.mydomain.com. When I hit that URL, it redirects me to a very long URL (unfortunately) like https://sites.google.com/a/mydomain.com/sites/system/app/pages/meta/domainWelcome, which just says: Google Apps Welcome to mydomain.com If you are the domain administrator get started creating your home page with Google Sites Great! I want to do that. So I click on the "If you are the..." link and end up at a screen where I can choose a template, a name, and some visibility options. If I click on My Sites, there isn't a "default" site, i.e. the one that www.mydomain.com displays. I figured that maybe I just have to create a site first, so I went ahead and did that. My first test was to create a site that was publicly accessible. I thought that maybe if I did that, the Google would decide that this must be my home page since it's the only one. But it doesn't, and I still get the "Welcome to" page. Under "More Actions", I didn't see anything interesting except for "Manage site". I went in there and had a peek around, and didn't see anything about using this as the default home page. Am I looking for something that just doesn't exist? I can't believe there isn't a way to modify the "domain welcome to" page...

• When computer turns on: keyboard/mouse/monitor don't work?

  - by dave

  the computer is barely good,at least i think..features Intel core 2 4 GB ram Nvidia Radeon 9600 512 mb Gigabite motherboad (the others i can't remember).. Used this computer for 3 years with no problem...The problem started one day after while it froze everything, then I shut down with removing the electricity power. A few hours later, I tried to log in to the computer but nothing moved. Nor keyboard nor mouse nor monitor worked, I was thinking that should be a delay so I left it some time. After a minute it turned off without my help around 30 seconds then it turned on automatically, but was the same problem like before and it goes again and again...any suggestions? If more info/specs required, let me know.

• Things to consider when building a continuous integration server?

  - by Dave

  I'm new to continuous integration, but immediately realize its value, and I want to get one set up right away. I have played with TeamCity and have it working in a VM great. Now, I don't want to spend money on another system, so I was planning on just doing the VM again on a faster machine (i.e. my dev system). There are a few questions that come to mind with this: Hard disk allocation - how big should it be? Sure, 60GB seems like more than enough, but people also used to think that we'd never need more than 64KB of RAM Backups - is it even important to back up the integration server? Sure, I guess it's nice so that one doesn't have to go through the entire configuration process again, but I would think that's about it. I could snapshot my VM every time I do a configuration change, and then do a backup of applications only (ignore the buildAgent stuff). Migration - if I want to go away from a VM on my dev system, to a new server, which maybe even runs Windows Server 2003, is it easy enough? Perhaps this is a particular point best suited for StackOverflow.

• Wired and Wireless Network Duplication

  - by Dave

  Howdy! Running into an issue when some of our client's have their laptop's connected via the wired ethernet network aswell as on the WLAN of the same network. There is know issues caused to the end clients.. BUT! Being a Managed Services Engineer i get pretty over the alerts that come through on our reports for machine's with the same hostname on the same network! We are not going to remove this monitoring because it does help a lot with detecting and stopping inferior users and things like that. So basically.. Question is, is there a way in Windows (third party programs welcome) to disable the wireless network when a wired network is connected and operational.. I know that Windows automticaly 'prefers' the wired network, however they are still both connected and therfore there is duplicate hostnames on the same network. Could also have stupid issues with DNS and things like that! Thanks!

• Windows 7 Laptop, cursor jumping after typing the letters "y" or "t" [closed]

  - by Dave K

  My wife has an HP laptop running windows 7. She has a very frustrating problem when typing: in some, but not all cases, typing the letter's "y" or "t" will cause the cursor to jump back a few lines or some number of words. The result is that she ends up typing over whatever it was that she was working on. (as a matter of fact, I just experienced this while typing this question on her computer with the phrase: "typing the letter..." above.) I've installed the latest drivers for her touchpad from Synaptic and disabled tap touching and gesture features to rule out simple unintended mouse clicks. Still the "y" and "t" keys continue to cause problems.

• Installing WiFi in a church for internet access

  - by Dave Griffiths

  Hi, a colleague at work asked this question: My local church want to get WiFi enabled in the whole of their offices and main church building. The offices and main building are in the same overall structure and so the signal does not need to travel outside to any other buildings outside this main structure. Where would I start on such a project and what kind of repeaters are needed (and how are they set up) given that some of the walls are pretty thick. Do you still have one ADSL line coming in to router or are there some options of having two lines coming in so that they isn't a single point of failure. Am looking at fibre for the broadband for increased speed. Any starting pointers appreciated.

• Using Excel Lookup Function and Handling Case Where No Matches Exist

  - by Dave

  I'm using Excel to enter data for an event where people register. A high percentage of the registrants will have registered for previous events, so we can their name and ID number. I'm trying to use the LOOKUP function in Excel to lookup the name and then populate the ID field with their ID number. This works well unless the value that is looked up is a new user that we don't already have details for. However, if the LOOKUP function can not find an exact match, it chooses the largest value in the lookup_range that is less than or equal to the value. This causes a problem since you can't tell if the match was exact (and the data is correct) or not exact and the match is incorrect. How do I catch non-matches and handle separately?

• FreeNAS plugins not able to access storage

  - by dave

  I've just setup a FreeNAS box and have a couple plugins (sick beard and SABnzbd) installed. Both of these have you select a directory where downloads should go. My storage is on /mnt/MediaVolume/ however when I navigate to mnt it's an empty directory. When I SSH to the box though, I can see it just fine. I'm thinking it may have something to do with permissions, but I'm not sure. Any suggestions how to allow these plugins to view/have access? Thank you!

• Custom metadata fields in Windows file manager (or other software)

  - by Dave Gaebler

  I'm trying to organize a collection of maybe 500 or so journal articles, stored in a combination of .pdf and .djvu formats. I'd like to be able to sort the collection by author(s), title, journal name, year, and subject keywords. Is there a way to create metadata fields for this information in the Windows file system (similar to how .mp3 files come with tags for album, title, track length, etc)? Or, if not, is there some software (preferably free) that can do something similar?

• What software will tell me if I've already downloaded a video? [closed]

  - by dave

  (I use Linux KNOPPIX (distro 7.0.2, ver 3.3.7) on hard drive.) I download videos of TV programs from the 60s and 70s (mainly from youtube). I copy the youtube URL then paste it into www.keepvid.com to download it (usually .mp4 format). Having now got dozens of such video files (and growing) on my hard drive, I'd like to organise them. WHAT I'D LIKE TO DO IS: Say I find a new vid (of a TV prog) on youtube (or another site), and I'm about to download it. It's possible that I've WATCHED IT BEFORE but have forgotten. So is there software out there that I can run which will do the following: Check for me if I've ALREADY WATCHED the vid that I'm about to download. At the moment, once I've watched a vid on my hard drive, I move the file to another directory called "Watched". But this of course doesn't alert me in the immediate way that I want. . It would crudely suffice, if the software told me AFTER I've downloaded the vid, if I've ALREADY WATCHED it (ie if it's already in my "Watched" directory, or perhaps in a "watched" list). I sometimes alter the filename of the original video file on hard drive, so this might spoil a comparison. If the software alerts me to the fact that I've already watched the vid (preferably BEFORE I download it), then this will allow me to confidently download only new vids that I haven't watched before, and save me duplicating my effort. I'd be most grateful if anyone can suggest such a piece of software, or an alternative solution. I'll be honest, I avoid software that infringes your privacy and control - you know, software that automatically does things behind your back, like upgrades itself over the internet, puts things on your hard drive that you didn't ask for, or sends information from your hard drive to websites.
