Hi,
If you search the forum you'll find numerous threads where the comparison between BDB SQL and SQLite has been discussed, and also where suggestions for tuning BDB SQL have been made.
From the Oracle Berkeley DB SQL API overview page under the Technical Resources subheading you can access several resources related to performance comparison between BDB SQL and SQLite.
Please review and follow the suggestions in those guides and from previous discussions on the forum and let me know if you see BDB SQL's performance improving.
Regards,
Andrei

    For Notes, if they are only on your phone I suggest you open them one by one and email them to your self so you have a backup of the text.  You can then go to Settings>iCloud and turn Notes to Off, then back On.  Then try creating a new note and see if it syncs properly to icloud.com and to your Mac.  If so, and if turning it notes off deleted the notes from your phone, you'll have to open each email and copy and paste the text into a new Note.
    My own experience with photo stream syncing photos to iPhoto is that it works great.  iPhoto automatically receives new photos from photo stream, and if configured to in iPhoto settings, it also saves a copy of the images to your iPhoto library so they are backed up.

  • I just bought an android phone and the previous owner of the number had an iphone and imessage wont work, how do I fix that?

    I just bought an android phone and the previous owner of the number had an iphone and imessage wont work, how do I fix that?
    I recently bought a Samsung Galaxy S4, and my wife has an iphone. We found out that imessage wont come through from her. After we went to the AT&T helpdesk they said that she could turn off imessage on her phone and that I would get texts on my S4. But then so would everyone else who has an iphone. That  won't work for everyone in my company that has an iphone. So what I am wondering is- since I recently got this phone, should I get a new number? Or should I contact ATT or contact Apple to try and get this number de-activated? I'm thinking I'll never get into the icloud account that this number is attached to, but maybe someone has some advice on that?
    I just sincerely want imessage to work on this phone and I'm willing to take the steps to do that.
    Please help

    Either one of the two should work - getting new number from carrier or contacting Apple to revoke phone number from imessage system.
    That is if your problem is described correctly.

  • HT6355 Can you send an audio message to a Android phone and will they be able to lisen to it?

    Just wondering if I will be able to send audio messages to friends with Android phones.

    Not with the Messages app. The option will only appear if you are messaging another iOS user. There may be other apps that will let you do that cross platform. Check the App Store.

  • Those of you with android phones and network extenders

    according to verizion tech support, there is a known issue with ALL android phones (it's an android os issue they say) that causes the phone to not display the signal strength properly when you're on a network extender.
    I have had mine for several months, called in several times about issues and was never informed of this until recently.

    I have the same problem, in fact I even have a 1mm gap between the rim and the top case, above the DVD slot. The rim is flexible and my right hand pushes it inevitably down when writing. The top case makes a slight noise when resting my hand on it, as it warps down and hits the DVD player. I've shown it to a genius but he said that's "normal" and if at all it is an cosmetic issue only and isn't covered. I told the technician to at least tighten things up when replacing my keyboard to fix my missing letter problem (didn't help the letters btw), which he confirmed, but there was no difference afterwards which indicates that the parts just don't fit properly, even with tightened screws. It annoys me a little but there are still other issues which are more irritating. I love the OS but I'm deeply disappointed by the hardware. Looks sexy but there are serious quality issues which puts my MBP behind many PC brands. Looks and coolness aren't everything.

  • Android Phone and Verizon-Yahoo Email account

    I've had my Verizon-Yahoo email account as my default email on my Android phone for nearly
    2 years. Suddenly, it does not sync with my actual email anymore and I cannot retrieve newly
    sent email to me.
    What happened?
    I deleted my Verizon-Yahoo email account thinking I could readd it without issue and now it
    won't add it. So, I am without my regular, most used email address on my mobile phone.
    How do I fix this problem step by step and what happened in the first place.
    If I canot retrieve my email there is no need for data. I need it for college classes and work,
    as well as other business uses.
    Can someone help me?
    In addition, I have been receiving ALOT of SPAM on my regular Verizon-Yahoo email over the
    past 6-12 months and I don't understand why. How do I fix that. I keep sending these adult ads
    and other SPAM to the SPAM folders but it keeps coming back!! Is someone signing me up
    for this stuff and how do i stop t from happening?
    Thank you for your assistance in advance.
    Blue.

    Hi:
    I experience the same problem when I downloaded systems updates on my Android Bionic phone, I was not able to sync my Verizon Yahoo email account.  I went through the same steps and nothing worked, until one savvy Verizon Wireless IT support agent told me to download the Yahoo Mail App on to my phone and that solved my problem instantly.  I logged in using my Verizon.net username and password and have been able to access my email with no problems ever since and have also updated my Yahoo Mail App and all works beautifully.

  • Android phone and apple computer?

    I just ordered a MBP 13". It should be coming in the mail within the next few days. I am also in the market for a new phone. All along I had been planning to go with the Samsung Galaxy 3. Now that I got an apple computer, though, I'm wondering if I should wait for the next iphone to come out and get it instead. I guess my question is, would i have a lot of issues with my android phone cooperating with my mbp? Is it a bad idea? Thanks in advance for the advice!!

    I had an android (Droid X) and had no issues while connecting it with my mac to upload pics/videos.  I now have an iPhone, and it is more convenient as they are meant to work with each other much better on terms of syncing calendars, itunes, photos etc.  That stated, I see no issues going with an android, just less convenience and lack of intergration with the mac.

  • My ipad 3 keeps dropping the wifi connection when my android tablet, android phone, and laptop have never had any issues.

    I just got a verizon ipad and am having wifi connection problems.  It will connect to my wifi but every 5 or 10 minutes it will drop the connection.  The only way to get it back is to go and manually connect to it again in the wifi settings.
    Is anyone else having this problem?  My android tablet and phone and laptop do not have this problem.

    It appears hundreds are having this problem.  You must not have done a search for this subject before posting.  Try a search for "wifi connection problem on iPad 3" and you'll get lots of information regarding this problem and a few suggestions you can try.

  • I have and android phone and I want to use my mac email account.  I cannot get the account to load

    I am using an Droid Razr M phone and want to put my mac email account back on it.  When doing the set up I constantly get a message that the there is not a connection to the Server.  I have followed all the instructions on how to do it but it consistanly will not let me set the account back up.  I am using the correct email address and password.

    Thank you so much for the help.  I had to enter my complete email address using me.com added to my sign in name and then after I got to the next page to enter the settings, I changed the address to not include the me.com information.  From there everything went through just fine.  This ended about a week of frustration trying with many folks at the Verizon Store to help me.  I'm so grateful for your help.

  • On Facebook, how can I share another person's photo album to my iPad? It shows up on my Android phone and on my computer, but not on my iPad.

    My son posted an album on Facebook; he took the pictures with a regular camera. I shared the album and it immediately showed up on my All-in-One computer and on my Droid phone on my Facebook timeline. It has never appeared on the iPad, so all my friends with iPads are not seeing this photo album. Do yoiu have any idea why?
    Thanks, Naomi

    I have discovered the same problem.  The timeline or group that the album is loaded directly to one can see the album and photos. However my habit has been to us my group as archive and then share the album with other groups saving me uploading several times.  If I look at on my desktop I and others like you see the shared album and friends with droid FB apo also see but ones with iOS FB app do not see the shared album be it on a friend/family member timeline another group.  I do not think this used to be, if almost seems that recent updates of the applicaion for iOS led to this problem but I am not certain. This is a big issue as I do not have time to upload and describe the same photos on the two to three other groups I share with.  I share your frustration, and there seem to be other things I do not see maybe it is all the shared photos/albums vs ones put on a timeline or group.  Not acceptable...

  • HT1386 i am new to iphone and would like to use songs from my media player as ringtones is theire a simple way to do this?i was using an android phone and all you had to do was play a song you likedand push a save as ringtone button.

    i want to download ringtones from music on my computer,media player or external hard drive using windows computer;

    Import the songs to your iTunes library, use iTunes to create your ringtones (see http://cnettv.cnet.com/create-free-ringtones-itunes-10/9742-1_53-50093086.html), then sync the ringtones to your phone.

    No, this has nothing to do with Apple or iTunes.
    You are attempting to use a device unsupported by Apple or iTunes with an app written by some other developer to emulate an Apple device.  Talk to the app developer.
    If you have an ATV, AirPort Express, or some other supported AirPlay receiver and the AirPlay icon is not appearring, then it is an issue that would be appropriate to be discussed here.

  • Android phone and iCloud

    The instructions in the Apple link http://support.apple.com/kb/HT4864 do not work when I try to set up iCloud on my Android device. I know iCloud works on my Android device because it did for 3 years until I accidentally cleared the cache today. Now I cannot set it up again. Does anyone know how to set it up? Apple Help desk has been utterly useless.

    My question was answered by NHLEVIN in an earlier reply to a similar post.  I had to tweak the outgoing settings to get it to work with my HTC Sensation, but work it did.
    [Protocol is IMAP]
    Do not use @mac.com or @me.com after username
    Incoming server is indeed: imap.mail.me.com
    Port is indeed 993
    Definitely select SSL/TLS and accept all certificates
    Now here's the zinger: Authentication should be LOGIN
    outgoing server settings are:
    smtp.me.com

    NONE for security type  Security: TLS

    Username again without @me.com or @mac.com
