If I bought an iMac from America would there be any differences/problems?
I live in Australia. If I bought an iMac from America would there be any differences/problems with me using it in Australia & connecting it to other Apple products (that were purchased in Australia)?
For that matter, you will receive cables which are incompatible with Australian electrical mains outlets.
Therefore, you will need a plug adapter.
You should also check with Customs for duties and import regulations and restrictions.
In my country, for example, all electrical devices imported from outside the EU are subject to duties and VAT and, if they are radios, TVs or any comparable device (and an internet-enabled PC is considered comparable), they must also be approved by the Department of Communications for compliance to radio frequency standards. In some rare cases, approval may be denied, most of the time it costs a very high fee. -

Try the following user tip:
"There is a problem with this Windows Installer package ..." error messages when installing iTunes for Windows -
When trying to install itunes the following appears. There is a problem with this windows installer package. A program for this install to complete could not be run. Contact your support personnel or package vendor. Any help?
a colleague of mine suffers from the same problem. did a quick look on the apple support pages. found many topics covering the same problem.
also saw 1 marked as correct answer... (just browse the discussion pages before you ask, this answer appearantly was sitting there from oct. 14...)

Hi Rick,
by "repair" I mean I went to the control panel, option - programs and features, and in the list of all my installed programs I selected "Apple Software Update". On top of the screen you find the options Uinstall, Change and Repair. I clicked the repair button and that did the trick. After the repair I could uninstall the program. I also uninstalled iTunes, Apple Application Support, Apple Mobile Device Support en Bonjour, thus all Apple programs. Then I installed iTunes 10.5 again and everything went fine.
Success,

Message says "there is a problem with this windows installer package. A program run as part of the setup did not finish as expected."
Any suggestions on what else to do??All - Thanks for the information.
I am receiving the same error, "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." Thought I found the answer in your replies above. However, I cannot find the "Apple Software Update" program either from Start -> All Programs or the Control Panel. I am running Windows XP, Service Pack 3. I would appreciate any additional guidance you have. -
HT4718 are there any reported problems with safari with the new OS X Mavericks?
My early 2008 iMac running OS X 10.9.2 all of the sudden has problems loading pages in safari. The problem timing is the same as the upgrade to Maverick. The computer is connecting to wifi and other devices such as iPhones and three PCs have no problems. The ISP is Xfinity. Are there any reported problems with Maverick and Safari?

Hi there, I have a problem with my iPod Classic (from 2009). Everytime I connect it to my computer (Windows), iTunes does not work anymore. Music is automatically deleted on my iPod. Any suggestions please?
Thanks, for info, iPod Classic is a slower machine compared the Nano, unfortunately, if you read these discussions, majority of the freezes involved iTunes 10. Although if might be just slow and some impatient user just disconnect the iPod ands cause more problems. ( Yes I also did that but safely by doing a iPod Hard Reset, before disconnecting).
Here is the Apple support article that may help you.
http://support.apple.com/kb/TS1717
or my usual solution for Windows Users.
Antivirus has a tendency to freeze iTunes sync Operation with iPod Classic, causing a timeout, which corrupt your iPod filesystem, so when iTunes can't read the iPod, it is pointing to this problem. Other causes is when your iPod hardisk is dying, or your battery is dying causing hardisk crashes.
My suggestion.
Connect your iPod to the PC and run chkdsk, to fix any iPod diskerror, then disconnect it, after chkdsk complete.
Disconnect your PC from Internet. (just to make sure no nasties creep into your system while you syncing.
Stop the Antivirus program
Connect your iPod to the PC, using a high speed USB 2.0 port at the back of your PC, do not use any USB Hub.
When iTunes Open up, Restore your iPod please, this is for iTunes to map correctly, to fix the corrupted filesystem.
When Restore complete, eject the iPod and reconnect again.
Sync your ipod, preferably manually Manage in small batches and disconnect after every batch, to check that all is well.
When all sync is complete, and iPod disconnected, start back your Antivirus and connect back the Internet.
Good Luck! -
Performance problems with jdk 1.5 on Linux plattform
Performance problems with jdk 1.5 on Linux plattform
(not tested on Windows, might be the same)
After refactoring using the new features from java 1.5 I lost
performance significantly:
public Vector<unit> units;

Performance problems with new Java Tiger style recommendations
Performance problems with jdk 1.5 on Linux plattform
(not tested on Windows, might be the same)
using the new style recommendations.
I need fast Vector loops for high speed mathematical calculations, some
hints about the fastest way to program that loop would be also great!
After refactoring using the new features from java 1.5 (as recommended from
SUN) I lost performance significantly:
using a vector:
public Vector<unit> units;
The new code (recommended from SUN for Java Tiger for redesign):
for (unit u: units) u.accumulate();
runs more than 30% slower than the old code:
for (int i = 0; i < units.size(); i++) units.elementAt(i).accumulate();
I expected the opposite.
Is there any information available that helps?
The following additional information I got from Mr. Shankar Unni:
I got some fairly anomalous results comparing ArrayList and Vector: for the
1.5-style loops, ArrayList was faster then Vector, but for a loop with get()
calls, Vector was faster. Vector was even faster than that using
elementAt(), which was a surprise:
For a million summing iterations over a 100-element array:
vector elementAt loop took 3446 ms.
vector get loop took 3796 ms.
vector iterator loop took 5469 ms.
arraylist get loop took 4136 ms.
arraylist iterator loop took 4668 ms.If your topic doesn't change, please stay in your original post.

Performance problem with recordset object
Hi,
I have a performance problem with record set object. Is it true using RecordSet object as argument to the method will cause any perfomance degradation?
here is my code.
finStmtList = selectFinancialStatements(rs, shortFormat, latestOnly, true);
I changed the code by populating the recordset in the method that called the above statement. previously the population of valueobject is within the select FinancialStatements.
Now the method looks like
finStmtList = selectFinancialStatements(ValueObject, shortFormat, latestOnly, true);
Is this fix will result in any performance gain?Can any one suggest me that the above RecordSet Object contains large number of records that counts up to 1000 rows and having 30 columns? I tested the application. But the performance varies from time to time.
Is there any other way to fine tune it? -
Performance problem with sdn_nn - new 10g install
I am having a performance problem with sdn_nn after migrating to a new machine. The old Oracle version was 9.0.1.4. The new is 10g. The new machine is faster in general. Most (non-spatial) batch processes run in half the time. However, the below statement is radically slower. The below statement ran in 45 minutes before. On the new machine it hasn't finished after 10 hours. I am able to get a 5% sample of the customers to finish in 45 minutes.
Does anyone have any ideas on how to approach this problem? Any chance something isn't installed correctly on the new machine (the nth version of the query finishe, albeit 20 times slower)?
Appreciate any help. Thanks.

) = 'TRUE'
;Dan,
customers 110,000 (involved in this query)
stores 28,000
Here is the execution plan on the current machine:
CREATE TABLE STATEMENT cost = 81947
LOAD AS SELECT
PX COORDINATOR
PX SEND QC (RANDOM) :TQ10000
ROW NESTED LOOPS
1 1 PX BLOCK ITERATOR
1 1ROW TABLE ACCESS FULL CUSTOMERS
1 3 PARTITION RANGE ALL
1 3 TABLE ACCESS BY LOCAL INDEX ROWID STORES
DOMAIN INDEX STORES_SIDX
I can't capture the execution plan on the old database. It is gone. I don't remember it being any different from the above (full scan customers, probe stores index once for each row in customers).
I am trying the query without the create table (just doing a count). I'll let you know on that one.
I am at 10.0.1.3.
Here is how I created the index:
create index stores_sidx
on stores(geometry)
indextype is mdsys.spatial_index LOCAL
Note that the stores table is partitioned by range on store type. There are three store types (each in its own partition). The query returns the nearest store of each type (three rows per customer). This is by design (based on the documented behavior of sdo_nn).
In addition to running the query without the CTAS, I am also going try running it on a different machine tonight. I let you know how that turns out.
The reason I ask about the install, is that the Database Quick Installation Guide for Solaris says this:
"If you intend to use Oracle JVM or Oracle interMedia, you must install the Oracle Database 10g Products installation type from the Companion CD. This installation optimizes the performance of those products on your system."
And, the Database Installlation Guide says:
"If you plan to use Oracle JVM or Oracle interMedia, Oracle strongly recommends that you install the natively compiled Java libraries (NCOMPs) used by those products from the Oracle Database 10g Companion CD. These libraries are required to improve the performance of the products on your platform."
Based on that, I am suspicious that maybe I have the product installed on the new machine, but not correctly (forgot to set fast=true).
Let me know if you think of anything else you'd like to see. Thanks.

Performance problem with CR SDK
Hi,
I'am currently on a customer site and I have the following problem :
The client have a performance problem with a J2EE application wich call a Crystal report with th CR SDK. To reproduce the problem on the local machine (the CR server), I have developped a little jsp page wich used the Crystal SDK to open a Crystal report on the server (this report is based on a XML data source), setting the new data source (with a new xml data flow) and refresh the report in PDF format.
The problem is that the 2 first sequences take about 5 seconde each (5 sec for the opening report and 5 seconds for the setting data source). Then the total process take about 15 seconds to open and refresh the document that is very long for a little document.
The document is a 600Ko file, the xml source is a 80Ko file.
My jsp page is directly deployed on the tomcat of the Crystal Report Server (CRXIR2 without Service Pack).
The Filestore and the MySQL database are on the CR server.
The server is a 4 quadripro (16 proc) with 16Go of RAM and is totally dedicated to Crystal Report. For the moment, there is no activity on the server (it is also used for the test).
The mains jsp orders are the followings :
IEnterpriseSession es = CrystalEnterprise.getSessionMgr().logon("administrator", "", "EDITBI:6400", "secEnterprise");
IInfoStore infoStore = (IInfoStore) es.getService("", "InfoStore");
IInfoObjects infoObjects = infoStore.query("SELECT * FROM CI_INFOOBJECTS WHERE SI_NAME='CPA_EV' AND SI_INSTANCE=0 ");
IInfoObject report = (IInfoObject) infoObjects.get(0);
IReportAppFactory reportAppFactory = (IReportAppFactory)es.getService("RASReportFactory");
ReportClientDocument reportClientDoc = reportAppFactory.openDocument(report.getID(), 0, null);
IXMLDataSet xmlDataSet = new XMLDataSet();
xmlDataSet.setXMLData(new ByteArray(ligne_data_xml));
xmlDataSet.setXMLSchema(new ByteArray(ligne_schema_xml));
DatabaseController db = reportClientDoc.getDatabaseController();
db.setDataSource(xmlDataSet, "", "");
ByteArrayInputStream bt = (ByteArrayInputStream)reportClientDoc.getPrintOutputController().export(ReportExportFormat.PDF);
My question is : does this method is the good one to do this ?
Thank's in advance for your help

Performance problem with query on bkpf table
hi good morning all ,
i ahave a performance problem with a below query on bkpf table .
SELECT bukrs
belnr
gjahr
FROM bkpf
INTO TABLE ist_bkpf_temp
WHERE budat IN s_budat.
is ther any possibility to improve the performanece by using index .
plz help me ,
thanks in advance ,
regards ,
srinivashi,
if u can add bukrs as input field or if u have bukrs as part of any other internal table to filter out the data u can use:
for ex:
SELECT bukrs
belnr
gjahr
FROM bkpf
INTO TABLE ist_bkpf_temp
WHERE budat IN s_budat
and bukrs in s_bukrs.
or
SELECT bukrs
belnr
gjahr
FROM bkpf
INTO TABLE ist_bkpf_temp
for all entries in itab
WHERE budat IN s_budat
and bukrs = itab-bukrs.
Just see , if it is possible to do any one of the above?? It has to be verified with ur requirement.
