Confused about RAM expansion...

Okay, so I'm not sure what to believe when it comes to memory in an Intel iMac...
I have a 24" 2.33 Ghz Intel Core 2 Duo iMac with 1 gb of RAM (2 - 512 mb chips).
Is one of those built in (soldered to the motherboard) or not?
I keep seeing some people saying (including who I just ordered new memory from) that you can install a maximum of 3 gb in this machine. Apple's manual claims 2.5 gb.
I've ordered one 1 gb and one 2 gb chip for this machine, and now I'm worried we just wasted our money on the 1 gb.
Please help!

No wurries! Nothing is soldered in. I have a 20" iMac of
the same vintage and updated the RAM a few weeks ago.

Re: Question about RAM expansion on Satellite M60

*RAM extention*:
What kind of memory should I buy if I want to extend it from 512MB to *2GB* or more for
*Satellite M60*-182 under Windows XP Home Editon with Service Pack 2
I mean: frequency, symbol, producer etc. to work properly?

Hi,
your machine can be upgraded to a maximum main memory capacity of 2GB, which means:
to expand the memory to the maximum limit what the machine is able to, you must put 2x 1GB DDR2 S0DIMM modules with a frequency of 533Mhz in both slots of your machine.
I would suggest you the following brands: Toshiba, Kingston, OCZ

IMac 21.5" confused by RAM

Good afternoon
It is a 21.5" iMac (A1311 EMC 2389 OS 10.5.8) with factory installed RAM is running really, really slowly and seems to be confused about what sort of RAM is installed. Recognizes that there are 2 X 2GB sticks installed, but doesn't know what type or speed of RAM or that it has any memory slots in which to install RAM. See screen shot below.
Swapped RAM with another set of sticks and moved the RAM to different slots to no avail.
System Profile - Memory recognizes slots (all 4 of them) and the sticks in the populated slots and the capacity of the sticks.
Activity Monitor doesn't show any process consuming ridiculous amounts of CPU time or memory.
Running Disk Utility to see how the drive is working and though it hasn't completed yet, nothing much is requiring repairs.
Any suggestions as to what to test/try next?
TIA
Greg

Vintage doesn't mean it is "old." Vintage means the age range of the model. Each model stays exactly the same components inside and out for a period of time. That period of time is known as its vintage. Think of wine.
Let's say you went to Best Buy and bought
PNY - 2GB PC6400 DDR2 SoDIMM Laptop Memory
simply because you had a Mac laptop that had that description of RAM in its documentation, you'd think you got the right RAM because of what the user manual said for the laptop. Would that be safe?
NO!
The EMC# is one way of knowing the age of the machine. http://www.everymac.com/ shows you several other ways. Regardless it is the age that says the season and year of the Mac's release. Now there were only three iMacs that were an EMC# of 2389:
http://everymac.com/ultimate-mac-lookup/?search_keywords=2389
So you need RAM that is compatible with a mid-2010 iMac, according to the RAM seller. No other RAM will work 100% reliably. And http://www.macsales.com/ and http://www.crucial.com/ are the two vendors I'm aware of that do list RAM by the specific Apple stated vintage.

Confused about XPostFacto and the 8GB Limit - Please help

Hi all,
I've been running XPostFacto 4.0 on my Apple G3 Desktop (Rev C, 640MB Ram, 533 Mhz G4 OWC CPU upgrade) for sometime and is running great.
But I have a question about the 8GB rule.
This computer only runs off of a Seritek SATA card. There is a 35 GB Raptor drive on it, the first 7.81 GB is the 10.3.9 drive, and rest is for applications and files.
I added a 160 GB Hitachi drive to the SATA card that I moved from my G4 MDD computer. It already has 3 partitions: 30 GB for 10.3.9, 10GB for OS9, and 115 GB for audio production files.
If I wanted to boot off the Hitachi drive, would I have to re-format and create a 8 GB partition?
As is, if I try to boot off the drive I just added, XPostFacto tries to synchronize the files, then it invariably crashes.
I tried reading the manual again, but I get confused about the Mac OS X Installer and the 8GB rule, and so on.
Thanks!

i wound up erasing the partition on the transferred drive and carboncopycloning the beige's OS X drive to it...and now the transferred drive is booting ok!
now, i'm thinking of copying the whole raptor drive over and re-partitioning the raptor drive (strangely, the raptor appears with about 9 partitions on Disk Utility, though the only two that i created are clickable...wonder if the OS sees this drive as something like scsi).
this is a little asides the point, but on my MDD, the 7200 hitachi seemed to test as "faster" than the 10000rpm raptor in most categories. would the 7200 drive infact be better for OS style-tasks?

I am confused about something. How do I read a book on my MacBook Pro? I can't find the iBook app anywhere, which is what I use on my iPad. The book I want to read is in my iTunes but I can't click on it. My iBook library does not show up in iTunes.

I am confused about something. How do I read a book on my MacBook Pro? I can't find the iBook app anywhere, which is what I use on my iPad. The book I want to read is in my iTunes but I can't click on it. Some of my iBooks show up in my iTunes but they are "grayed" out. The only books that respond in iTunes are audiobooks and that's not what I'm looking for. Is this a stupid question?

Nevermind - I answered my own question, which is I CAN"T READ ANY BOOKS I purchased in iBooks on my MacBook Pro. If I want to read on my mac I have to use Kindle or Nook. Which means any book I've already purchased through iBooks has to be read on my iPad. Kind of a drag because there are times when it's more convenient for me to read while I'm sitting with my Mac.

Confuse about the injecting entity in EJB 3.0?

Hi all,
I have an customersBean which is inherit from customersRemote and my problem is i' am little confuse about injecting the entity(customer).
Where can you apply the EntityManagerFactory is it outside on EJB or Inside the EJB? means outside EJB is use the web application or java application. i have and example.
this is inside on EJB...............
public class CustomersBean implements com.savingsaccount.session.CustomersRemote {
@PersistenceContext(unitName="SavingAccounts")
EntityManagerFactory emf;
EntityManager em;
/** Creates a new instance of CustomersBean */
public CustomersBean() {
public void create(int id, String name, String address, String telno, String mobileno)
try{
//This is the entity.
Customer _customer = new Customer();
_customer.setId(id);
_customer.setName(name.toString());
_customer.setAddress(address.toString());
_customer.setTelno(telno.toString());
_customer.setMobileno(mobileno.toString());
em = emf.createEntityManager();
em.persist(_customer);
emf.close();
}catch(Exception ex){
throw new EJBException(ex.toString());
in web application, i'm using the @EJB in customer servlets.
public class CustomerProcessServlet extends HttpServlet {

Confused about logical table source

Hi,
I'm confused about logical table source(LTS), there are 'General', 'Column Mapping', 'Content' tabs in
LTS, in General tab ,there are some information,like 'Map to there tables' and 'joins',
just here, we have created relationships in physical layer and BMM layer, so I would like to ask what's the use of the 'joins' here?

Hi Alpha,
Valid query, when you establish a complex join it is always between a logical fact and dimension table.Consider a scenario,
Example:w_person_dx is an extension table not directly joined to a fact but joins to a dimension w_person_d.
When you model the person_d tables in BMM, you ll have a single logical table with w_person_d as source.If you have to pull columns from both w_person_d and w_person_dx tables in a report, you add dx table as inner join to persond table in the general tab.Now when you check your physical query, you can see the inner join fired between the two dimensions.

Confused about transaction, checkpoint, normal recovery.

After reading the documentation pdf, I start getting confused about it's description.
Rephrased from the paragraph on the transaction pdf:
"When database records are created, modified, or deleted, the modifications are represented in the BTree's leaf nodes. Beyond leaf node changes, database record modifications can also cause changes to other BTree nodes and structures"
"if your writes are transaction-protected, then every time a transaction is committed the leaf nodes(and only leaf nodes) modified by that transaction are written to JE logfiles on disk."
"Normal recovery, then is the process of recreating the entire BTree from the information available in the leaf nodes."
According to the above description, I have following concerns:
1. if I open a new environment and db, insert/modify/delete several million records, and without reopen the environment, then normal recovery is not run. That means, so far, the BTree is not complete? Will that affact the query efficiency? Or even worse, will that output incorrect results?
2. if my above thinking is correct, then every time I finish commiting transactions, I need to let the checkpoint to run in order to recreate the whole BTree. If my above thinking is not correct, then, that means that, I don't need to care about anything, just call transaction.commit(), or db.sync(), and let je to care about all the details.(I hope this is true :>)
michael.

http://www.oracle.com/technology/documentation/berkeley-db/je/TransactionGettingStarted/chkpoint.html
Checkpoints are normally performed by the checkpointer background thread, which is always running. Like all background threads, it is managed using the je.properties file. Currently, the only checkpointer property that you may want to manage is je.checkpointer.bytesInterval. This property identifies how much JE's log files can grow before a checkpoint is run. Its value is specified in bytes. Decreasing this value causes the checkpointer thread to run checkpoints more frequently. This will improve the time that it takes to run recovery, but it also increases the system resources (notably, I/O) required by JE.

Confused about extending the Sprite class

Howdy --
I'm learning object oriented programming with ActionScript and am confused about the Sprite class and OO in general.
My understanding is that the Sprite class allows you to group a set of objects together so that you can manipulate all of the objects simultaneously.
I've been exploring the Open Flash Chart code and notice that the main class extends the Sprite class:
public class Base extends Sprite {
What does this enable you to do?
Also, on a related note, how do I draw, say, a line once I've extended it?
Without extending Sprite I could write:
var graphContainer:Sprite = new Sprite();
var newLine:Graphics = graphContainer.graphics;
And it would work fine. Once I extend the Sprite class, I'm lost. How do I modify that code so that it still draws a line? I tried:
var newLine:Graphics = this.graphics;
My understanding is that since I'm extending the Sprite class, I should still be able to call its graphics method (or property? I have no idea). But, it yells at me, saying "1046: Type was not found or was not a compile-time constant: Graphics.

Thanks -- that helped get rid of the error, I really appreciate it.
Alas, I am still confused about the extended Sprite class.
Here's my code so far. I want to draw an x-axis:
package charts {
    import flash.display.Sprite;
    import flash.display.Graphics;
    public class Chart extends Sprite {
        // Attributes
        public var chartName:String;
        // Constructor
        public function Chart(width:Number, height:Number) {
            this.width = width;
            this.height = height;
        // Methods
        public function render() {
            drawAxis();
        public function drawAxis() {
            var newLine:Graphics = this.graphics;
            newLine.lineStyle(1, 0x000000);
            newLine.moveTo(0, 100);
            newLine.lineTo(100, 100);
I instantiate Chart by saying var myChart:Chart = new Chart(); then I say myChart.render(); hoping that it will draw the axis, but nothing happens.
I know I need the addChild method somewhere in here but I can't figure out where or what the parameter is, which goes back to my confusion regarding the extended Sprite class.
I'll get this eventually =)

Confused about standby redo log groups

hi masters,
i am little bit confuse about creating redo log group for standby database,as per document number of standby redo group depends on following equation.
(maximum number of logfiles for each thread + 1) * maximum number of threads
but i dont know where to fing threads? actually i would like to know about thread in deep.
how to find current thread?
thanks and regards
VD

is it really possible that we can install standby and primary on same host??
yes its possible and i have done it many times within the same machine.
For yours confusion about spfile ,i agree document recommend you to use spfile which is for DG broker handling if you go with DG borker in future only.
There is no concern spfile using is an integral step for primary and standby database implementation you can go with pfile but good is use spfile.Anyhow you always keep pfile on that basis you created spfile,i said you make an entry within pfile then mount yours standby database with this pfile or you can create spfile from this pfile after adding these parameter within pfile,i said cause you might be adding this parmeter from SQL prompt.
1. logs are not getting transfered(even i configure listener using net manager)
2.logs are not getting archived at standby diectory.
3.'ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION' NEVER COMPLETE ITS RECOVERY
4. when tried to open database it always note it 'always' said system datafile is not from sufficiently old backup.
5.i tried 'alter database recover managed standby database camncel' also.Read yours alert log file and paste the latest log here..

Confused about SOAP

Hi all,
As far as I know, SOAP is initially designed to be an XML based
RPC protocol.
But Java API for XML Messaging (JAXM), which is actually a
messaging API (and not RPC), is also based on SOAP.
How do they fit to each other?
In a few words, what does actually SOAP define?
I am confused about that, can you help me?
Any idea will be appreciated.
Thank you

In a few words -- no. Try here:

Confused about passing by reference and passing by valule

Hi,
I am confuse about passing by reference and passing by value. I though objects are always passed by reference. But I find out that its true for java.sql.PreparedStatement but not for java.lang.String. How come when both are objects?
Thanks

Hi,
I am confuse about passing by reference and passing
by value. I though objects are always passed by
reference. But I find out that its true for
java.sql.PreparedStatement but not for
java.lang.String. How come when both are objects?
ThanksPass by value implies that the actual parameter is copied and that copy is used as the formal parameter (that is, the method is operating on a copy of what was passed in)
Pass by reference means that the actual parameter is the formal parameter (that is, the method is operating on the thing which is passed in).
In Java, you never, ever deal with objects - only references to objects. And Java always, always makes a copy of the actual parameter and uses that as the formal parameter, so Java is always, always pass by value using the standard definition of the term. However, since manipulating an object's state via any reference that refers to that object produces the same effect, changes to the object's state via the copied reference are visible to the calling code, which is what leads some folk to think of java as passing objects by reference, even though a) java doesn't pass objects at all and b) java doesn't do pass by reference. It passes object references by value.
I've no idea what you're talking about wrt PreparedStatement, but String is immutable, so you can't change its state at all, so maybe that's what's tripping you up?
Good Luck
Lee
PS: I will venture a guess that this is the 3rd reply. Let's see...
Ok, second. Close enough.
Yeah, good on yer mlk, At least I beat Jos.

PSE 7 confusion about folder location, help needed

Here's some background: I'm using PhotoShop Elements 7 on Win XP. I have an external firewire hard drive I use for overflow/backups. Originally, this showed up as a K: drive on my system.
I added a RAID controller and two more drives to stripe as a single drive for temp space rendering movies. This ended up as a K: drive and the external moved to L: However, when I did this there were some pictures from my catalog that I had on the external drive. I have used File > reconnect missing files to handle the moves, but PSE is still confused (very).
PSE has started to mix up the RAID (K:) and external (L:) content. If I move a set of pictures (e.g. a folder of them) onto the external drive (L:) via drag and drop in the folder location view, the folder will show up empty on the L: heirarchy, but will show up as a gray folder icon in the K: RAID drive hierarchy. If I open up windows explorer, the RAID drive will appear empty. In other cases (I'm not sure when/how yet), pictures physically end up on the RAID drive itself instead of the external. I have uninstalled both the external drive and the RAID drive and reinstalled them both, but they are still getting confused in the folder view by PSE. I've also tried moving content outside of PSE and just reconnecting missing files, but it still wants to put things under the K: RAID drive instead of the external L:.
I've searched everywhere I can think of for a description of what gray folder icons in the folder location view means and can find none. I'm not sure how to convince PSE that there's nothing on the RAID K: drive and it shouldn't try to connect the two. Any suggestions?
Thanks,
Jim

Thank you! I ran psedbtool and the output shows the catalog has the wrong drive letter for the L: drive.
Is there a way to make PSE forget about the K: and L: drives that it is so confused about so that it can relearn of their existence? If I use the drive letter reassignment to fix PSE, it will break other apps that are now dependent on the current drive letter assignments. I've tried removing all files from the L: drive, but it's still remembered as part of the catalog.
Thanks,
Jim

Confused about schema..

I'm currently working on a project using VB 2010 Express and Oracle 11g XE. On my Oracle My SQL Developer, I am currently logged on as 'user X' and I created three tables. All of which are just listed on the 'tables' tree. Does it mean that 'user X' is like a schema when compared to MySQL?
I have already integrated my database to my vb project and is working fine ATM. I'm just really confused about schemas in Oracle 11g XE.

I am confused about Icloud. I have a 5 year old Macbook, a 2 year old macbook and a 5 year old mac mini. What exactly do I need to do to get all this connected via Icloud. I also have an Iphone 3G. Help please!

I am confused about Icloud. I have a 5 year old Macbook, a 2 year old macbook and a 5 year old mac mini. What exactly do I need to do to get all this connected via Icloud. I also have an Iphone 3G. Help please! Also, I still don't understand exactly what the benefits are. At the moment it seems a lot of hassle to change a system that's been working perfectly well and that I'm very happy with. I'm not at all sure whether the mac mini (1.66 GHz INtel Core Duo) can be brought up to the relevant spec to run ICloud. Any thoughts?

There are two aspects to iCloud. One is simply getting an account, or migrating a mobileme account to iCloud. The second part is using the various features of iCloud to sync contacts, calendars, use music match or photo sharing, and store iWorks documents.
First to get an iCloud account:
If you have a mobileme account, you can migrate by simply logging onto www.icloud.com (ignore any references to Lion and just click through to complete the migration). If you have OS X Lion or an iOS 5 mobile device, you can create an iCloud account on that device using any valid AppleID.
Once you have an account, you can use JUST the mail account if you wishi - it is a standard IMAP account so you would set it up like any other IMAP email account you have, in whatever client program you use to read email.
To use the OTHER feautes of iCloud, your computers will have to be running OS X Lion (10.7). Your iPhone 3G will never be able to use iCloud as it cannot run iOS 5 (you need a min. of an iPhone 3GS to run iOS 5).
The requirements for OS X Lion are here - http://www.apple.com/macosx/specs.html You need a min. of a Core 2 duo processor so you mini is not capable of running Lion.
So, in your case, the single reasons for iCloud would be if you have a mobileme account, then use the online www.icloud.com to migrate your account so you do not lose your @me.com email address. You can use iCloud email (without using any other iCloud features) by setting it up as IMAP mail with these settings - http://support.apple.com/kb/HT4864
If you want an iCloud account and do NOT already have a mobileme account, you will need to upgrade one machine at least to Lion in order to be able to create an iCloud account.
