Best location for FSFO observer

Hello experts.
I have a question which our team is pondering over.
We have two data centers. One is primary, the other is the DR site.
I'll call them Primary Data Center and DR site for this posting.
We are running Oracle 11gR2 on IBM P7 servers (AIX 7.1) - not that it matter for the purpose of this question, but just for reference.
Our question is where would be the most ideal location to have the observer, and why?
The options we are considring include:
* separate LPARs on a separate server at the Primary data center
* separate LPARs on a separate server at the DR site
* put on same box (in same LPAR) as the standby database at the DR site
(We do not have a third location, otherwise that might be the most logical site.)

Hello;
Given your options I would go with :
separate LPARs on a separate server at the DR site.
If the DR server area is not available observer is not very important.
Maybe in a different room at the DR site if possible.
Just my opinion. But if the standby site is not available, what do you have?
The other thought is a virtual solution at a third site since there's almost no load to worry about.
Best Regards

What I was trying to state was use the "separate LPARs on a separate server at the DR site". Since if your DR is not available, you don't have Data Guard.

  • Best location for Project.fcp

    Just getting started and testing. I am using a FW external drive for my media (the Scratch drive assigned via System Prefs). All is going well (so far).
    Is there a best location for the Project.fcp file? I think that I read that it best reside on my startup drive.
    But, I also read (I think) that the media files and project files should be kept in the same folder (I don't understand why). I would suspect that the Project.fcp file can be anywhere, just like any other document file. Correct?
    Thanks,
    Sonny

    I asked the same question over three years ago!
    Here was Tom's reply to me that has an added bit of info that might be useful:-
    "+Putting the project file on the system drive is generally considered good practice. I'm not sure how much actual performance improvement you'll see, but the media might be less likely to have dropped frames. It also means, if your autosave vault is on the media drive, that you have project file backups on a second hardware device in case one fails."+

  • Best location for iTunes Library

    Just trying to figure out where the best location is to put the iTunes Library to improve streaming to the AppleTV.
    I have an AirPort-n that acts as a remote hub for my Tivo, PS3, and now AppleTV (all three are hard-wired to the AirPort-n). Since there’s the ability to connect a USB drive to the AirPort-n, would it make sense to co-locate the iTunes library on a drive connected to the AirPort-n with the wired AppleTV (that is, if it gets the data directly from the Library), or, does the streaming video actually have to flow through (processed by) the host computer (Mac) that ‘owns’ the iTunes Library?
    Making sense???
    THX!

    does the streaming video actually have to flow through (processed by) the host computer (Mac) that ‘owns’ the iTunes Library?
    Correct. There must be a copy of iTunes with the library you wish to sync/stream on the host computer, and iTunes must be running for the Apple TV to connect to it (the Apple TV does not pull directly from the library). So from that standpoint, it really doesn't matter where you keep the library, as long as iTunes on the host computer can find it.
    I'm sure others will express opinions, but I'm uncomfortable with the reliablity and performance of drives connected to a wireless base station (remember that if your Apple TV is connecting wirelessly, you'd essentially be doubling the wireless bandwidth you use any time the Apple TV syncs or streams), so unless you have a good reason (use with other computers, for instance) to have the drive connected to the Airport base station, you might just want to connect it to your host computer.
    Hope this helps.

  • What is the "best" location for images?

    2 Problems:
    - IPhoto has developed many picture icons that are no longer pointing to the photo they once were, there is just a icon and no image, the file name is visible in the info pane of iPhoto. They are still represented by icons in iPhoto in the photos list and in the appropriate events however the pictures are apparently not where iPhoto thinks they should be.
    - Understanding where photo files are located when brought into iPhoto. I have moved to importing all my photos via photostream, which I believe is supposed to download all photos into the iPhoto library, but appears to be downloading some into the downloads folder.
    In the preferences/advanced tab I have selected "Importing: Copy items to the Iphoto Library"
    It appears that my actual image files, some form my old version of iPhoto on and old computer, some from my iPhone that were downloaded directly and some via the iCloud photo stream are going to and are in different locations.
    I believe it would be good to place all my image files in one location, that is visible to all applications and finder.
    So for instance, if I need to find all the pictures of a car I want to sell on craigs list or attach them to an email, I can find them via a finder window without having to open and go through the iPhoto app. I had created many "Albums" to do this in iPhoto that had worked to achieve this.
    A location like ...username/pictures/iPhoto Library/master/2013/car pictures/front.jpg
    Opening and looking at pictures in my current version of iPhoto on my current Macbook;
    I see some files in the iPhoto library are in appropriately named folders and with picture names, if I had given them a name and a folder (album) in iPhoto on old or new macbook.
    Like: ...usernames/Pictures/iPhoto library/Masters/2006/Home/Kitchen.jpg
    Others are in places like .../usernames/Documents/old macbook 867/Pictures/iPhoto library/Masters/2006/Home/Kitchen.jpg
    Still others are in my current downloads folder
    I have purchased iPhoto library manager and used the rebuild library feature. It did not resolve the problem.
    I believe I will have to basically create a new iPhoto library by merging librarys and importing some pictures.
    I would just like to keep as much of the organization, albums and organizing into events I have done as possible and not have to re do it all.
    The location of photos iPhoto is NO longer referencing correctly and photos iPhoto IS still referencing correctly appears to be in several different places.
    These locations have many photos that show up in iPhoto and are referenced correctly and some that have icons that are not referenced correctly.
    1.) The ...username/downloads folder/...  Contains many image files, mainy .jpg's some are from old computer and some are from new computer via iphone
    2.) The ...username/documents/old macbook 867/pictures/iPhoto Library/... with appropriate folder and file names
    3.) The ...username/documents/old macbook 867/pictures/...jpg  Just folders with image files in them, not in a iPhoto library
    4.) The ...username/Pictures/iPhoto Library/...
    Any help on how to rebuild the library and keep pictures in the correct location would be appreciated.
    Have iPhoto version 9.5.1
    OS 10.9.1
    Sorry for the long question, trying my best to be clear.
    Thank you

    Sorry but I have no idea what your problem is
    However it is cealr tha tyou do not understand how to use iPhoto
    what exactly do the following mean?
    - IPhoto has developed many picture icons that are no longer pointing to the photo they once were,
    If you click on a thumbnail and a different photo opens tehn Back up your iPhoto library, Depress and hold the option (alt) and command keys and launch iPhoto - rebuild your thumbnails - this may take seversl tries
    If you click on a thumbnail and you get a ! then Back up your iPhoto library, Depress and hold the option (alt) and command keys and launch iPhoto - rebuild your iPhoto library daabase - this will not work if you have moved or deleted those photos using the finder or cleanup or tidy up software
    In the preferences/advanced tab I have selected "Importing: Copy items to the Iphoto Library"
    Was it ever unchecked? that is stongly not recommended
    Understanding where photo files are located when brought into iPhoto. I have moved to importing all my photos via photostream, which I believe is supposed to download all photos into the iPhoto library, but appears to be downloading some into the downloads folder.
    Assuming that you have a default managed library then all photos are in your iPHoto library - any that are not were not done by iPhoto but you the user or other sofware
    So
    I believe it would be good to place all my image files in one location, that is visible to all applications and finder.
    By default and very strongly recommended all Photos in iPhoto are in the iPhoto library and are accessaboe to all other programs using the supported methods as described in the user tip on accessing your iPhoto files - https://discussions.apple.com/community/ilife/iphoto?view=documents
    However they are not accessable via the finer - Why? Because i{Photo replaces the finder for you photos and you NEVER access them using the finder - - this statement was one clue that you do not understand how iPhoto works and how to use it
    And this also indicates that you do not understand - this is NOT how you access photos - see above
    So for instance, if I need to find all the pictures of a car I want to sell on craigs list or attach them to an email, I can find them via a finder window without having to open and go through the iPhoto app. I had created many "Albums" to do this in iPhoto that had worked to achieve this.
    A location like ...username/pictures/iPhoto Library/master/2013/car pictures/front.jpg
    So you either need to learn how to use iPhoto or switch to a different product - iPhoto does not work like you want - with iPhoto you do not directly access your photos and you can not control or change where they are stored

  • Best Location for Wireless Router in 2 Story House

    Hello. There was a similar post to this before, but it didn't quite address my concern. I live in a two story house. The router is currently placed in one half of the first floor. I am connected to with my dekstop wirelessly via an extended-range usb adapter. Everything else held equal, is it better to place the router in the highest location possible? In other words, am I more likely to get better reception anywhere in the house if I place the router upstairs (and as close to the center of the house as possible)? Most of the people in my house use their laptops downstairs while I am stuck upstairs with my desktop and wireless adapter getting a decent but not entirely desirable connection (it was very low and would turn off randomly, but I changed the router channel to 11 and now it seems to be consistent but at around 3 to 4 out of what seems to be 10 bars. Ideally, since I like to game and desire the highest speed, I would set up the router via ethernet to my pc upstairs while putting it in a location that will not severely limit the connection downstairs... that is why I ask if it is better to have the router upstairs; if it is, then I will have all the justification I need to try to reposition it.
    Also, as something of a more techinical question. How does the radio broadcast from the wireless routers work? Does the signal shoot up and out from the antenna tips? Can it shoot down? Even if it shoots up, is it still better to have it in a higher location?
    Sorry for the rambling, but I would appreciate any input. Thanks.

    Your router will broadcast the signals in all directions(not just upstair or downstairs)...You should place your router in the center of your house...
    Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
    In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4.
    Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna (if external) should be vertical...

  • Best Location for iTunes Library Files

    Greetings:
    Ive moved all of my iTunes media to NAS.  Is it best to have the iTunes library files on the NAS or should I leave on PC.  What are the considerations?   thanks in advance.  John

    It depends a bit on the size of the library. Each action with iTunes causes the database to be updated and there can be some detectable overhead if the library files are stored remotely. On the other hand it is then much easier to backup and restore or migrate the library to a new system if everything is located in a portable layout on that NAS. See Make a split library portable for some background. In practice it may be best to move the library files to local storage for performance but be prepared to move them to the correct path to make the library portable when the need arises.

  • Best location for application files

    In our current WebLogic environment (WLS 4.51), we have seperate document roots
    for each of te 12 seperate applications being served up in seperate WebLogic instances.
    We are migrating to WLS6.1, and I am not sure if I should continue this practice.
    All applications will be under the same domain, and some common utility .jar and
    .war files may be targeted to several servers in the domain (email servelts, search
    servlets, etc.). However, I am no tsure I want all these directories or .jar/.war
    files to beunder the same "applications" folder. If I put them under /apps/Java/$app_name/
    I can deploy them fine from the console. If I do this, will I lose the auto_deploy
    feature? Is there any inherent dangers to doing this? Mostly, I want to keep app1's
    files in a different location than app2's.

    Please see my inline replies:

    feature?Yes. if you are keeping your applications outside of the applications directory they would not
    be auto-deployed. It is necessary to keep the applications in the
    /config/domain_name/applications directory, if you want to have the auto-deploy feature to
    work. Also, we recommend to use auto-deployment only during development and turn off the
    feature in the prod environment.
    Is there any inherent dangers to doing this? Mostly, I want to keep app1's
    files in a different location than app2's.Maybe this strategy helps you:
    You can have all the applications in the applications directory in the exploded dir format. In
    this case, they will be auto-deployed on the Admin server. Using the console, you can target
    them to different servers in the domain (analogous to different WLS 451 server instances).
    Now, if you change a particular file (jsp) in the webApp, then you will need to just touch the
    REDEPLOY file. The Admin server will check that the timestamp for this file has changed and
    redeploy the application to the concerned target servers.
    So, by maintaining an exploded directory structure for each webApp in the applications
    directory, you will be able to keep the files separate and still achieve redeployment.
    More details can be found at:
    http://e-docs.bea.com/wls/docs61////adminguide/appman.html#1029683
    Also, as everything is a webApp now, each webApp has its own documentRoot. So if you have 12
    webApps, each has a different docRoot automatically.
    hope this helps.

  • Best Location for Deploying Common File in WSP

    I have a small wsp containing a masterpage and a stylesheet that will act as the standard branding for many SP site collections in my company.  One of the requirements is to have a footer with a link to a Terms & Conditions PDF in the masterpage.
     So I'd like this PDF to be deployed in this WSP with the masterpage and styles so that we don't have to manually add it when a new site collection is created.
    My question is where is the best place to deploy this file so that I can easily link to it from anywhere in the site collection (i.e. top level site vs subsite)?  I was thinking a mapped folder would be best, but I'm not sure, and frankly I'm not sure
    how to link to a file in a mapped folder.  Am I making this too difficult, should I just put the file in one centralized public place and hard-code the link in the master page?  Please let me know your thoughts.  Thanks.

    Use mapped folder (Layouts) to deploy your files. In custom web part solution, map folder with your solution and copy the files in it. All other site collections can access files form mapped folder.

  • HT1178 Best Location for Time capsule (Does it help if placed Higher in the room?)

    1500 Sq Ft Ranch - Hallway between computer room and open sapce of living room, kitchen, & dinning room + entrance to Master bedroom
    and would it be better to locate in the very center of the home.
    Our Older time Capsule reaches to the open area in the center but at times will only pick up in the center of the open space. Other times it very stron in the entire center living area.
    I'm expecting the capsule to reach all of the area up to the master Bed room. Not used in the bed room. On our back deck, (52 feet by 18' long) with roof over deck it will be strong on entire deck when the window in the computer room is very small opening at the top. ( old time capsule)
    Can place the Newtime capsule in any area.
    Computer backs up to Hallway

    Thanks for any suggestions.
    Ron

    Well, as you know it is impossible to ever predict wireless performance in advance....but the general rule would be that it is better to locate the Time Capsule higher, rather than lower.
    Ideally, the Time Capsule will be located where wireless devices have a clear line-of-sight signal path to the Time Capsule. Another way of saying the same thing is to imagine that the Time Capsule is a water sprinkler and you want to get as much of the house as wet as possible.
    Or, think of the Time Capsule as a strong light. You want to light up as much of the house as possible where wireless devices will be used.
    You will likely have to make compromises keeping in mind that a typical wall constructed of sheetrock and 2 by 4s will absorb...on average....about 15-20% of the wireless signal. Brick, cement, or plaster over lathe will absorb a much higher percentage of the signal. Users often forget that large mirrors are in fact a large metal barrier, not allowing much of the signal to pass through.
    If you find that the signal will not cover all of the areas where you need a wireless signal, you will need to consider adding an AirPort Express to "extend" the wireless signal further in one direction.

  • Best Location For HDTV??

    Ok When U Buy a HDTV do U supposed To keep it In a Dark Low Place Like the Basement Or can u use a HDTV on a Higher Level Let say In The Attic would that be a good idea To Have one there or is that Too High to recieve a signal?

    I'm quite surprised you have worse reception in an upstairs room than in the basement.
    Typically, for the purposes of over the air reception of radio signals (including broadcast TV), the higher the better for the antenna.
    Of course, if you have a roof mount antenna (or cable) feeding house wiring, then all bets are off as the wiring could be counterintuitive.
    In the case of cable, the cable feed might enter in the basement (and hence be strongest there) and may go through splitters before being routed to the rest of the house.
    In many cases roofmount antennas leverage existing wiring, and guess what - that existing wiring often starts from the basement and the antenna's feedline is dropped to the basement and then signals are routed back up through the house.
    Edit:  To the original poster,
    Cable TV or Over-the-Air Broadcast?
    If OTA Broadcast, are you using one antenna to feed in-wall wiring of the house, or do you have an antenna attached directly to the TV?

  • Best location for home folders

    setting up a new server - with about 150 home folders - and say a maximum of 30 concurrent users:
    Does it help to distribute the home folders across 3 or 4 drives?
    Will it be faster with external Thunderbolt drives?

    Generally yes and yes.  The faster the drive(s) the better.  Try to predict load to distribute across storage or even servers.  Watch for hitting the IOPS wall on your storage if you are dealing with a lot of small files.  This has been trouble in a few locations.
    But more important than the drive is your connection to the network.  Do the simple math.  Let's assume you have 1000Base connection and you are supporting wireless clients.  The wireless is N and you are able to get about 50Base a connection.  This is aggregated into your base stations and the base stations connect at 1000Base to the network.  You will likely have multiple points of access.  30 concurrent users are getting the full through put (beginning of session, saves, and end of session) would be 1500Base exceeding the capacity of your access point if all 30 are on the same station. 
    Now consider the impact if these are wired devices.  The more bandwidth you give the server the more requests it can handle as log as the disk array can keep up.
    Give your server the fastest network connection you can.  Consider bonding to get to 2000Base as that is inexpensive (assuming you have good switches already) and easy to implement.  10GigE is also available but if you don't have the switches already this can be pricey fast.
    Be aware of folder redirection (there are some great resources in this forum on how to implement) and also understand the apps that will be used.  Not all apps are network home friendly.

  • Best locations for FCP Projects and Events?

    Back in the olden days when FCE 4 and FCP 7 ruled the roost, it was generally considered that the best setup was to have the Project files on the System HD and the Capture Scratch (Events) on another.
    Is this still the ideal setup or should the Projects be kept with the Events on an external HD?
    Are there any advantages associated with the various configurations?

  • Best directory for isnatlling Unix Applications in Snow Leopard?

    Can someone advise me on the best location for installing Unix Applications in Snow Leopard? Should I install them in /usr/local or create a new /opt directory for them? My understanding is that OS X 10.6 does not come with /opt. I prefer to install manually and not use third party software (e.g. Fink).
    Many thanks.

    If you are downloading and compiling your own sources, then /usr/local/... would be the expected location.
    If you are using the MacPorts.org already ported packages, then get placed in /opt/local/...
    If you are using Fink.sf.net already ported packages, then the get placed in /sw/...
    And for a few Unix tools at work, and I can not modify my host system, I put it in $HOME/local/..., which works for me because my company uses NFS to allow the use of my same home directory on multiple systems. This works as long as I do not exceed my corporate home directory storage quota
