Setup of a standby and a streams - architectural question

Hi,
I am thinking about a standby (prodstdby) for my Production (prod) database.
For another part of the company we need to setup streams (HIS), this will copy only a part of the database ( some sort of archiving) to a database called HIS. During the years, HIS will become larger and larger, PROD remains only current data.
I am thinking to do this with Physical standby for PRODSTDB
and streams for HIS.
Or.. and this is my question: could this be easily done with Real Application Cluster?
We are in 10GR2.
HIS <----- STREAMS---- PROD

Hi,
- easier to install --> no as it'll be something to install more then just a normal database without RAC so if you don't know enough of it it'll be a charge more to install it and use (maintain) it. (But it can be usefull :-) )
- easier for maintenance --> not especially
- last but not least: more automated --> not more automated but autamoted as well as with no RAC.
- and less risk in case of failure --> less risk in case of failure is definitely true for the primary under RAC of course, it's the point of it !
RAC will just make you gain protection in case of failure in the primary side prod or hist or both. If a node fails then the other(s) take the hand. With or without delay for the apply is nearly the same as logs are shipped.
Greetings,
Loïc

  • Configuration setup for active-standby and active-active

    Hi
    Having two sites separated by WAN and want to distribute the load between those two sites as Active-Active setup. want to whether it can be possible to have a active-standby pair at each site if not what is the work around to setup.

    I would suggest the following setup as 'best practice' for this requirement.
    At site A have a TimesTen A/S pair hosting data in range 'A' - 'M'. This provides local HA for this dataset. Remote readonly subscriber of this A/S pair located at site B. This provides read access to data 'A' - 'M' at site 'B'. in the event of a total failure of site A this remote subscriber can be converted into the active of a new A/S pair (located at site B).
    Same setup in reverse for site B.
    If the hardware is adequate you only need two machines at each site since you can host the readonly subscriber on the same machine as one of the local A/S pair datastores and if you need to do a site level failover you could host both A?S pair on a single pair of machines. Of course availability will be higher with 4 machines at each site. It is a cost/benefit trade off.
    This is really the only viable/supported setup to have both sites active if using IMDB cache.

  • How do I transfer photos and videos from my iPhone to my PC using iCloud and Photo Stream?

    I am quite confused with how iCloud and Photo Stream work to transfer photos and videos from my iPhone to my PC. I recently ran out of my space on iPhone so I need to delete all of my pictures and videos but I first want to confirm that they have all been transferred over to my PC. I have iCloud setup but here lately I have been getting the warning message that iCloud could not perform it's backup because I was out of space on iCloud. I had not worried about it since I figured that all of my pictures and videos were on my iPhone anyway and the only reason I would need them on iCloud would be for a backup. Anyway, how can I confirm that everything has been transferred over to my PC? Then, what is the quickest way to delete all of my exisiting photos and videos off of my iPhone? I found the Photo Stream folder on my PC... Is everything automatically added to this when I connect my iPhone to my PC? If I delete something off of my iPhone is it deleted from the Photo Stream folder on my PC? Please help and thank you! I just don't want to lose any of my stuff!

    You don't move them to iTunes or an iTunes account.
    You should be importing them to your computer regularly as you would with any digital camera.

  • Duplication Issues with Photo Sync via iTunes/iPhoto and Photo Stream/iCloud (Detailed Scenario Given)

    Hi Everyone,
    I'd like to share an issue I am having with photo syncing between my iDevices.
    Here is how I USED to sync my Photos between my iDevices (no issues with photo duplication)
    Note: In this scenario, I use iTunes and iPhoto on my Mac. iCloud and Photo stream have NOT been activated in this case.
    1. Take photos via iPhone that saves in Camera Roll
    2. After a month or so, I will connect my iPhone to my Mac.
    3. Import my Photos in iPhoto and arrange  Events and Photos in monthly sections and add some of them in a separate Albums (ex. Written Notes Photos) for easy access.
    4. Once the import is done, iPhoto prompts an option to delete photos in my Camera Roll which I do as I like to start a fresh month with empty Camera Roll in my iPhone.
    5. In order to access the Photos I have imported in iPhoto in my iPhone, I go to iTunes and sync all my photos to my iPhone. This syncs my events, photos, faces, albums as they have been arranged in iPhoto in my Mac. (I cant delete them in my iPhone once they are synced. I have to delete in my iPhoto and sync again to have similar setup in my iPhone which isn't a problem).
    NOW I decided I don't want to manually go through all this process and went on to enable the Photo Stream ON in my iPhone and iPhoto with iCloud.
    THIS IS WHERE THE PROBLEM ENSUES.
    1. I  Take photos with my iPhone that saves in Camera Roll
    2. This automatically syncs with my Mac due to Photo Stream which a really convenient.
    3. It syncs automatically to Photo Stream, Events, Photos, Faces section in the iPhoto and I put put some of them (notes) in a separate album.
    THE PROBLEM:
    The Photos does not show up in the Album, Events and Photos Folder in my iPhone. They are only shown in Camera Roll. So I thought to sync using iTunes so the new Photos will be arranged in their appropriate folder like it used to with my prior process of syncing. This worked, HOWEVER the photos in my iPhone started showing DUPLICATES! Apparently, one comes from Photo Stream (which, if I delete on my phone also deletes in all my iDevices) and the other duplicate is from the iTunes sync (this sets up my photos as arranged in iPhoto which is what i WANT to happen as Photo Stream does not sync them accordingly).
    SOLUTION I AM IN SEARCH FOR:
    I want to be able to take photos with my iPhone that automatically syncs in iCloud AND iPHOTO AS ARRANGED IN MY MAC (Albums, Events etc) WITHOUT PROBLEM OF PHOTO DUPLICATES.

    Other folks have resolved similar issues by trashing  the iPod Photo Cache.

  • Standby and PCIE 2.0 x16 problem

    Good day Forum,
    I have encountered 2 issues with my setup (I will list the setup specifications below).
    Standby issue: My computer is unable to go S1 nor S3 standby despite having a new operating system installed. Power settings set at Maximum Performance for Windows 7. When I clicked 'Sleep', the system will power down but it will power up again (without having the display shown). I have ruled out USB issues because I have taken out all USB peripherals connected to it right before it shuts down from standby and connected back again after it powered up.
    PCIE issue: My PCIE 2.0 x16 graphic card is slots into the blue coloured PCIE 2.0 x16 slot. There are 2 PCIE-based cards which are connected to the motherboard via the PCIE slot but they are not connected to the 2nd PCI 2.0 x16 slot (hence, no reason for the speed to drop to x8). The issue here is not concerning the bandwidth of my graphics card but merely a question of curiousity as to why the interface speed drops from PCI-E 2.0 x16 to PCI-E x16 (v1.1). Any ideas? Here are some of the screenshots I took before and after:

    That's suppose to be. It's self adjust pci-e [1.xx <==> 2.xx] depend of VGA power needs.
    When the VGA works in higher performance mode then will be auto switched to pci-e 2.0 automatically.

    A new BIOS can help with this. If you already use latest BIOS for your mainboard, then you can ask msi about it here for further beta bios: http://support.msi.com/
    P.S: Try turn off/Disable the "EuP 2013" BIOS option 1st, then retest

  • Using Airport Express for wireless printing and possibly streaming music

    I have had the toughest time figuring out this Airport Express. It seems there are so many different ways to set it up. I've tried to read forums but just can't seem to wrap my head around what I need to do. I tried awhile back to join my network wirelessly but was having problems.
    I don't really care about extending my current network. My internet service is through Verizon Fios and the router they provided works just fine and don't have any issues with connecting anywhere in the house. I bought the AE to be able to print wirelessly and stream music from my iMac in another room.
    So to print wirelessly obviously the printer has to be plugged in to the AE, but does the AE have to be plugged into my router? Or can I have the AE anywhere in the house wherever the printer is? When I print, am I using my existing network or do I have to disconnect a computer from the wireless network and access a 2nd network to be able to print?
    My first priority is to print wirelessly. If I can get it to work It'd be cool to stream music from my iMac. Obviously the AE needs to be where the speakers are, but again, does the AE have to plugged in to the router? And again, is this done through my existing network? Or do I have to stream music through a 2nd network? I apologize if i'm asking the same questions that have been asked in previous forums, I just haven't been successful thus far so wanted to see what response or tips I could get. Thanks.
    My existing network has "WPA Personal" security set up on it if you need to know that.

    but does the AE have to be plugged into my router? Or can I have the AE anywhere in the house wherever the printer is?
    If you configure the Express correctly to "join" your FIOS wireless network, you can position it anywhere that it will receive a good, strong wireless signal.
    The trick to setting the Express up to "join" is that you must choose exactly the same type of security for the Express as your main router is using. This is tricky when you are using devices from two different manufacturers because they often use different names for the same thing.
    For example, when you say that the FIOS is setup to WPA Personal, we really need more information. There's usually a TKIP or AES associated with WPA. You have two choices on the Express for WPA settings, WPA2 Personal or WPA/WPA2 Personal. We can only guess which one might be the correct match for your FIOS network and if you don't choose the right setting, the Express cannot join the network and you have to start the configuration all over again from scratch and try the other setting.
    Does your Fios have a setting for WPA2 Personal? Some manufacturers label this WPA2-PSK (AES). Or, maybe you find that your FIOS is using WPA-PSK (TKIP), which is the same thing as Apple WPA/WPA2 Personal. It's confusing. That's why we tell users to choose wireless gear from the same manufacturer. It's much easier when two devices talk the same language.
    When I print, am I using my existing network or do I have to disconnect a computer from the wireless network and access a 2nd network to be able to print?
    If you have a compatible printer plugged into the USB port on the AirPort Express and have "installed" the printer by setting it up, you will be able to print over your existing wireless network.
    First things first. You need to get the Express setup to "join" correctly and get a green light. Then, tackle the printer setup.

  • Question regarding standby and cables...

    I just got FIOS yesterday and so far (one day lol ) I love it.  I love the speed of my internet.  I was paying for BOOST and in the beginning I was getting 3.5mb daily but over the last 4 months that has become 500kb and I had had enough. 
    On to my problem.  I have the new Motorola MRDVR HD in the livingroom and the 7100 p2 STB in the bedroom.  Last night watching a movie in the livingroom (HD) it failed, I restarted and it played, failed again and restarted then all seemed fine but in the bedroom I have a bigger problem.
    I understand the 7100p2 does standby and thats fine but I haven't bought a new TV yet so I am using an Epson projector with COMPOSITE cables.  I suspect the standby and composite cables are not playing nice but while watching anything 20-30 min in the STB just goes off...and the only way to get it back on is to pull the plug on the STB.
    I have tried every other iteration of menu/on/off/anything but once it goes into standby ( I guess it is anyway although I was watching something) It will not come back on.  Sometimes it tries...black screen for a few then back to the EPson start screen and from there the only way is to pull the STB plug.
    If it's a composite cable/projector problem Ill get another TV (the tech is SOOOO old I figured it would work np) but if there is some sort of interaction between the STB and TV that this cannot handle... I have other ways to hook it up but none will get me sound right now, s-video/vga to DVi to HDMI, but none of those will do sound (today anyway).
    I have searched all over the webs and cannot find even mention of someone trying to use these old old old cables with a newer STB... help...:-)
    EDIT: The motorola starter guide does show composite and s-video but no mention of standby.

    Actually the standby is just when you power the cable box off, its not really off, it is in standby waiting incase there is an update. All the Verizon STB's do this.
    Component cables have no communication between STB and TV. Only the HDMI cable has any 2 way communication, so there should be no compatibility issue.
    If the STB is powering off after 20-30 minutes and you cannot power it back on without a reboot, then I would guess that you have one of two issues (that I can think of anyway).
    It could be that the STB is overheating. Its designed to power down when it gets too hot and stay off until it cools down. Is the STB out in the open? Does it have anything on it, like a towel or another electronic device? Is it inside an entertainment center that has an enclosed back or front?  If so, it may just be getting hot and you may need to move it out into the open or move whatever is on it.
    If its not overheating then it may be just a lemon of a stb, I'd contact Verizon and ask them to swap it out for you.

  • Rented movie not playing. I have 81Mbps Internet and can stream anything else HD. it's not WiFi either because signal strength is full and I can view anything other than rented movies on apple TV unit. it charges me for renting but doesn't play

    Rented "Gone Girl" on apple tv. It charges me, but will not play for more than 4 seconds at a time. I have exercised every step of apple's troubleshooting and nothing fixes the problem. I have a very strong, steady 81 Mbps Internet connection speed and can stream any other HD through the apple tv except for this rented movie. This is not the first time this has happened either. I just gave apple $6 for free and am currently watching the movie streaming through my cable provider's on demand channel with ease. Oh yeah, and when I seek apple support for the issue, apple wants $2 just to contact someone! Give me my money back please and I will never attempt to use your poor tv service again.

    The limitation of approximately 200 titles has been discussed before, we can't be sure whether it will be something that gets fixed or not. I'm not really sure what your other issues are, if I use search instead of lists, I find whatever I want and am able to rent or purchase subject to those options being available for that particular title.

  • I'm trying to setup my new iphone and the Apple ID it asks for is my friends old Apple ID that she no longer has access to. How can I fix this?

    I'm trying to setup my new iphone and the Apple ID it asks for is my friends old Apple ID that she no longer has access to. How can I fix this so I can use my new phone? The first step asks for my iCloud info but then asks for my friends after I agree to the terms.

    The iPhone is new, has never been used. When asked if I want to set it up as a new phone, restore from an iTunes backup, or my iCloud backup I selected iCloud. It then askes for me to sign in with my Apple ID, I then agree to the terms, then it asks for me to sign into my friends Apple ID. She and I have used each other's computers in the past so I assume this is where her information is coming from. The problem is she no longer had that email or Apple ID and has no way of gaining access to it and therefor I am unable to proceed.
    I suppose my question is, how can I remove her information from mine so I can setup my new phone using iCloud. Also, I have already checked my Apple ID online and nowhere on my account is her information listed.
