Can I config timesten not to hold all data in memory?
In our production environment we use a server with 32GB memory to run Timesten, but developer machine only have 2GB memory. Now we are going to fix some issue that require duplicate the production data to Developer machine, can we have config timesten not to hold all data in memory so that it is possible to duplicate the production data to Developer machine? Is timesten support something like cache table as hsql?
http://hsqldb.sourceforge.net/web/hsqlFAQ.html#BIGRESULTS
TimesTen is an in-memory database. All the data that is managed directly by TimesTen must be 'in memory' and the machine hosting the datastore must have enough physical memory or system performance will be severely degraded.
The only way to have a combined in-memory and on-disk solution is to introduce a backend Oracle database (10g or 11g) and use TimesTen cache connect. Of course, this then becomes a very different configuration and depending on what 'issue' it is that you need to investigate and fix the change to a Cache Connect configuration may hinder that investigation.

JPA - How to load all data in memory
Is it possible to load all data in memory using JPA, do many transactions like create, delete, update and finally make a commit when I want?.
I am trying to do something like Weblogic does, the user locks the console, does many transactions (create services, delete accounts, update costumers etc) and at the end when he presses a button, all changes are committed.Yes. Of course. There are tradeoffs. First, if you loaded all data into memory, you likely have a small database or a huge amount of RAM. :^)
Big I digress. What you are talking about is either conversational or transactional state. The former would be implemented at your view-controller level (e.g., hold onto the results of the user's selections until the work is done, and then submit as a batch). Sometimes this is simply session state, but generally, you are handling this at the web or controller tier. It is solely a decision to enhance user experience.
Another possibility is to hold onto the transaction for the whole time that the user is modifying data. This is in some ways "easier" than the first method. However, it likely will not scale beyond a non-trivial amount of users. Generally, you want to hold onto a transaction for the shortest possible time.
So, my recommendation would be to load your objects into memory using JPA. Keep those in session state (or write them to a 'working copy' database table or the filesystem to save memory). Then submit all the requests in one go back to JPA (in one transaction).

Now with a little more space, I believe this to be a simple fix just not for me! I have recently moved from the UK to the Cayman Islands and there lies the problem, 'voltage' ....
My UK PC was 240v and has now been destroyed so when I secured a new laptop 110v and downloaded itunes I was told by 'itunes' as my ipod was linked to another PC it would not/could not sync to my ipod. As the ipod holds ALL my music files this is a major drag. Can anybody tell me how to unassociate my ipod with my old PC so I can sync with my new laptop.
Regards RobAll computers sold in the past 10 years are univeral insofar as voltage is concerned, so it may have been destroyed but not because of voltage. The right thing to do is to restore the backup that you must have made of your old PC to your new laptop. Then you will not lose anything when you sync the phone.

sorry sir,
i am confused in last line you wrote,
" This will erase the phone but you will be given an option at the end to restore to an existing backup, if you have one."
i did not understand last sentence - if i have one? you mean to say if i have data or not in my iphone?
i have many pictures, messages, contacts which are very much important.
so will it be all restore and will be backup again in my iphone if i restore?
i am extremely sorry to interrupt you again.
waiting for your quick reply

Time Machine not backing up all data
Hello All,
I just bought a Time Capsule 2TB and have Macbook pro early 2011 (running Lion OSX). I wanted to do to a time machine backup. Everything went well. I got it connected good and the backup started very weel. My HDD is about 400 GB and when the time machine started back up it started with data and the progress bar showed the total data to be back up (400GB), but then it backed up only 30 GB out of 400 GB.
I have most of my files in iphoto and ivideo. Is this normal? Why didnt TIme machine did not back up all 400GB?
Any idea?Then there are two possibilities:
The backup failed, but you didn't see the message. See #C2 in Time Machine - Troubleshooting. It will show you how to locate the message(s) that describe the problem, then help you fix it. If that doesn't help, post back with details, including all the messages.
Or, some things didn't get backed-up. A partial explanation could be iPhoto -- if the iPhoto app is open when a backup runs, Time Machine may not be able to back up your iPhoto library. It will attempt to "catch up" the next time, but in the meantime you may not have any backups of it.
That's unlikely to be the whole difference, though. Does the figure of 400 GB seem reasonable to you -- can you account for most of it? -

If your email accounts are IMAP (which includes most major email providers like Gmail & Hotmail) then you don't have to sync them as they will automatically sync with all your devices. All you have to do is enter the username and password on your iOS device. You can speak to your ISP to confirm if your particular email accounts are IMAP.

I just got a new iMac. was following the onscreen instructions to do migration assistance and I guess it connected to my old iMac via wi fi. It never instructed me to connect via firewire. Now it seems to have stopped. what can I do that won't completely mess it up? how Long will it take to do over wi fi?
Your new iMac does not have a Firewire port so you ned this adapter:

to connect the two machines together and migrate simply follow the instructions in:

Can you make random notes on a calendar date
How can i record notes on a date in ical without an event
Hi TO,
Here's an example that does what you want.
Since you didn't give starting values, I had to make some assumptions that made the example numbers in your table fit the calculations. As it turned out, a 2400 initial amount and 1666.69 increments each month produced 22402.68 after 12 months.
I used an auxiliary table, Start, to contain the starting date, and placed the 'current date' in A1 of the main table. For the automatic version, use the formula =TODAY() where I've placed the current date.
The copy of Table 1 (Table 1-1) shows the result on the fifteenth of the following month.
Formula:
B4: =2400+(DATEDIF(Start :: A1,$A$1,"M")*C4)
Format the cell as number, with two places after the decimal, or as Currency, if you want the currency sign.
Regards,
Barry -
sir this reply i received from you -
" You're welcome. Once you phone is in recovery mode, as is is now, you no longer have the option to back it up. Your only now is to restore it. Restoring the phone will erase it, then give you the option at the end to set it up as a new iPhone or restore it to an existing iTunes or iCloud backup, if one exists. If you don't have an existing backup, I'm afraid that unfortunately your data will be lost."

Data Merge not picking up all data fields
Hi,
I've been having a problem, posted here: http://forums.adobe.com/thread/1217090
Essentially, I have been using the script 'CSV2Tables' to prepopulate simple 2 column tables with information drawn from a CSV data source.
The tables consist of a title, and a block of information about that specific subject. Many of the blocks of information I am importing also contain data tags (<<DataTag>>)
The plan is to use CSV2Tables to populate the tables, then change data source and run a normal ID Data Merge to replace all of the <<tags>> within the tables with information from a second CSV data source.
The problem is, CSV2Tables is importing the data and prepopulating the tables just fine, but the data tags that are found within each body of text are being picked up as plain text (as Peter Spier has pointed out, they are being drawn from a plain text stream rather than being dragged from the Mail Merge panel) so when I try to run the ID Mail Merge, none of the fields are found within my document.
My question is - is there a method, or script available out there that can essentially do a Find/Change within a document, and replace plain text that appears like this <<PlainText>> with a Data Tag that is recognised by ID, which will allow me to run a Data Merge?
I have been told to check out some of the commercial plugins available out there, but registering and setting up demo's would require me to contact our IT provider for each, and that would be an exhaustive process.
Any help is much appreciated.Hi,

My iPad 3 usually syncs with a Windows PC, but since I got the new Mac I thought I'd now sync with it. But when I connected the iPad and tried syncing, iTunes is warning me that I am about to loose all existing data in the iPad and it will be replaced with data from the Mac. I do not have any data on the laptop yet, though I have a lot of photos, music, videos and stuff, most of all many paid apps and games! Now how do I do the syncing without loosing all this? How can I tell my laptop to keep all data in the iPad intact, make a copy of it in teh laptop and go on from there?
It's a problem that happens when you change libraries. Backward syncing only works if you have the Apps on your iDevice downloaded into iTunes through the Transfer Purchases option, but this still does not cover your media (Movies.. Songs.. etc.)
When you double click on a file to play it in iTunes, it will duplicate that file and place the new copy in iTunes' directory. By default, all the files that appear in iTunes must come from this location, and you do not have this directory 'filled up' with the same files you used to sync to.
I guess Apple could solve this issue by allowing iTunes libraries to automatically tag media to particular devices for ease of syncing, but what if you want to sync the same device with 2 different libraries on different computers?
I normally don't sync apps with iTunes at all, because iCloud handles that. -
How do I zero all data on Time Capsule?
I just got the new 2TB Time Capsule and I want to get rid of my previous 1TB one, but I can't figure out how to zero all data on that disk, and I of course don't want to sell my Time Capsule to a stranger with sensitive data on it. Does anyone know how to wipe out all the data on a Time Capsule?

Launch Airport Utility, double-click on your old Time Capsule in the left column, then click on "Disks" in the toolbar, click on the Time Capsule Disk on the left, then click on the "Erase..." button. -
I try to sync my nano and get: the ipod cant be synced because there is not enough free space to hold all of the items in the items library (need 100MB) - I have a new computer?? can you help me understand this message: what to do?
Hello pryan1012,
What this message means is that you have more music in your itunes library than there is free space in your ipod.
I had this same issue at one time. This is what helped me put my music on the ipod. I used manually manage.

Hope this helps.

Using home share, I can import some songs from my son's computer but not others. All the songs were purchased with the same apple id. Err msg:"There was a problem downloading ... You do not have enouggh access privileges for this operation. Please check that the connection to the network is active and try again." The network appears to be fine . I can import other songs from his library. The same songs cause me a problem each time I try. My husband had no trouble importing the same songs I have trouble with. I get the same error message if I try to import the same songs from my husbands computer as well. "Command I" appears to show the same protections on both the songs I can import & the ones I cannot. My husband and son are both running OS 10.6, while I am running 10.7. I think I had this problem even before I upgraded, but I am not certain.

Welcome to Apple Discussions..
My first suggestion is to Repair Disk. Here's how:
Insert Installer disk and Restart, holding down the "C" key.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
Please post back and let me know how that goes.
