Performance problems with CS2 under Vista

I used to run CS2 under XP and everything was fine! A technical fault with the PC caused the hard drive to wipe itself, and for some silly reason I installed Vista when I reinstalled everything.
The PC is very powerful and has plenty of RAM, but CS2 runs very badly on it. It can run normally, usually for the first few seconds of use, but will inevitably slow down. Anything to do with an onscreen image, such as marking an area, painting, anything. I mean it really slows to a crawl. Positioning the cursor on a location and rapidly moving it to one side, there can be a delay of several seconds before it moves! This really makes the software unusable. Thing is, I cant tie down what it causing it. The CPU use hits 100% which is the obvious reason, but why it is, I dont know. There doesnt seem to be any disc access. Also, it doesnt depend on how large or small the image is. It happens even editing an image as small as 400x400. If there is one thing, then it may well be that it is when the image is enlarged so that it is bigger than the window it is displayed in. In other words, the scroll bars are present. It never seems to happen when they are not present. Does anyone have any ideas? All the drivers are fully up to date, nothing is causing problems. the machine scores 5.9 on the vista performance test and it has 4GB of ram.

Am I looking in the wrong place?
Were can it be modified?
I was adjusting it in the window color and appearance. Advanced. The only problem was that I couldn't adjust the color of the window frames under aero. Specifically things like the status bar. I currently use an old style windows setup because I can set everything to mid gray, including scroll barss, status bars and so on. It may be boring, but is best for the type of work I do.
By the way, I have cured the problem. Under Performance Visual Effects, I disabled all the silly stuff that is hardly ever used like "Slide theTask barar Buttons" and the problem went away. Some of these are not actually used unless you use Aero anyway. I don't know which one was causing the problem, but anyway, it's gone!
I would still like to be able to set all the colors under aero, so if anyone can tell me how, would be greatly appreciated.

I'm having problems with CS2 (mainly illustrator and photoshop

I'm having problems with CS2 (mainly illustrator and photoshop ) randomly shutting down while trying to save a file. Reformatted my laptop for fear of a virus and reloaded... I have gotten nowhere.
Please Help!

CS3 still had issues with the preferences becoming corrupt, so a possible workaround would be to reset the preferences.
The file is called AIPrefs and is located under 'Documents and Settings/User/Application Data/Adobe/Adobe Illustrator CS3 Settings'. It is a hidden file. Delete it with Illustrator closed and when you launch the program again the file will be rebuilt.
May be it is also sounds like you need more memory for your computer. If you can navigate to your computer's memory controls, and allow your operating system to use a portion of your hard disk drive (HDD) as RAM (maybe 2Gb or so) it may solve your issue.
How is about: http://www.filerepairforum.com/forum/adobe/adobe-aa/illustrator/383-%E2%80%8Bcorrupted-fon ts-in-illustrator-file-urgent-help-need – resource has non-commercial specialty
Third party software Illustrator Repair Kit also must be good solution
It has free demo version at:- http://www.illustrator.repair/
Hope this will be helpful.

Problems with over/under absorption on production cost centers - GBB AUI

Hi,
I have a problem with over/under absorption on production cost centers after month end closing.
We are using material ledger CKMLCP and actual activity rates from direct cost centers are settled directly to products using GBB AUI account determination.
Unfortunately from time to time there appears a significant balance on production cost centers after running CKMLCP. What might be the reason? I have analysed line items on cost centers but cannot find any answers.
We are using assignment of cost elements to particular activity types (function splitting), and I have checked that all cost elements are assigned to proper activity types.
Best regards,
Karol

Hi,
DP90 is used for Resource related billing, is broad term basically when you performing service that time you have to raise billing on the basis of resources which you had spend for perticular service
DP90 is run on the basis of DYNAMIC ITEM PROCESSOR,
http://help.sap.com/saphelp_di471/helpdata/en/59/54fc37004d0a1ee10000009b38f8cf/frameset.htm
I will tell you one process from the prspective of CS module
Create notification >> Create service order >> Confirm service order >> Resource releted billing (genrates sales document) >> Invoice to customer with refrance to sales document.
Now here DP90 is used to determine material,IN SALES DOCUMENT because CS module don't have billing feature as like SD Billing.
In CS module activities/Operation,but in SD module we speciefy material codes
So DIP determines XYZ activity/operation is ABC material in SD

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;
The new code:
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?

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.

Performance Problems with "For all Entries" and a big internal table

We have big Performance Problems with following Statement:
SELECT * FROM zeedmt_zmon INTO TABLE gt_zmon_help
FOR ALL ENTRIES IN gt_zmon_help
    WHERE
    status = 'IAI200' AND
    logdat IN gs_dat AND
    ztrack = gt_zmon_help-ztrack.
In the internal table gt_zmon_help are over 1000000 entries.
Anyone an Idea how to improve the Performance?
Thank you!

You can't expect miracles. With over a million entries in your itab any select is going to take a bit of time. Do you really need all these records in the itab? How many records is the select bringing back? I'm assuming that you have got and are using indexes on your ZEEDMT_ZMON table.
In this situation, I'd first of all try to think of another way of running the query and restricting the amount of data, but if this were not possible I'd just run it in the background and accept that it is going to take a long time.

Performance problems with EP 6 and MS IE

Hi everybody,
since a couple of days, we are facing a sever performance problem with our SAP EP 6.0. When I access the system with MS Internet Explorer 6.0, it takes 5-10 minutes after the Login. With Firefox Browser, the performance is ok. Therefore I assume that it must be a problem with the IE settings. Does anybody know a solution?
Best regards,
Michael

There are a few things that this could be. I've seen the setting "Empty Temporary Internet Files folder when browser is closed" cause a lot of performance problems (This is in the advanced settings in your IE).
This will cause your cache to be cleared out each time the browser is closed and cause a lot more data to be downloaded each time you login to the system.
For more analysis I'd recommend putting a tool like HTTPWatch into your IE browser and seeing which requests are using the most time.

Problems with ViaVoice under Leopard, especially key mapping problems

ViaVoice's behavior has changed considerably under Leopard. First I will discuss the key mapping problem, since I'm eagerly looking for an answer to this problem. At the end of this post, I will voice some of the other problems I've experienced for those who may be interested. The key mapping problem may be specific to the fact that I use a foreign keyboard with a US version of ViaVoice.
INTRO:
I have used ViaVoice on my Mac for years, more or less without problems (ViaVoice's bugginess is notorious).
Those who know ViaVoice will know that one has two general options for dictation. One can dictate into ViaVoice's so-called SpeakPad, which allows special formatting, editing and dictation error correction within the dictated text, or one can dictate into "external" software such as Microsoft Word, in which case ViaVoice just sends a string of characters to that software. SpeakPad appears to make strong use of the operating system's built-in functionality for character formatting, document formatting, etc.
*MY PROBLEM*
I have a German keyboard on my PowerBook, yet dictate in US English. When I dictated into SpeakPad under Tiger, all characters appeared correctly. However, when I dictated into Microsoft Word using Tiger, I had to switch the keyboard mapping from German to US to get all characters (that means including the characters that are located at different positions on a German keyboard than they are on a US keyboard such as y, z, apostrophes and parentheses) to appear correctly.
Under Leopard, things have changed. Now it doesn't matter whether I dictate into SpeakPad or Word; the results are the same and many characters do not appear correctly.
If set to a German keyboard, y and z appear as expected. To name a few irregularities:
"(" appears as ")"
")" appears as "="
apostrophes appear as "#" and
";" appears as ","
If set to a US keyboard, y and z are interchanged. "(" and ")" appear as expected. Apostrophes appear as "\" and ";" appears as ","
By comparison, if typed (as opposed to dictated, as in the examples above) "correctly" (i.e. based on the letters printed on the keyboard) on a German keyboard set to imitate a US keyboard:
y and z are interchanged
apostrophes appear as "|"
"(" appears as "*"
")" appears as "(" and
";" appears as the symbol for "less than"
Since I don't have a US keyboard, I can't say how it would behave if set to imitate a German keyboard, i.e. if there's a correlation to the results I get when I dictate.
Since I was previously able to dictate correctly into SpeakPad by setting the keyboard to "German" and into Word by setting the keyboard to "US," I presume that this is a problem in Leopard, not ViaVoice.
*OTHER PROBLEMS WITH VIAVOICE UNDER LEOPARD*
In addition to the aforementioned key mapping problems (that may be specific to those of us with foreign keyboards), ViaVoice appears to have lost considerable functionality in Leopard. I cannot access SpeakPad's Preferences and the correction window. Moreover, the traffic-light like window buttons have disappeared from the VoiceCenter (although they work if you click where they should be). SetupAssistent appears to function.
I've written to Nuance about these problems, but have little hope that they will invest the time in producing a patch since they haven't released any updates since 2003.

Thrums1,
I've never had to "register" ViaVoice after updating the system. I thus suspect you haven't fully followed my above, three-step advice (particularly step 3).
1) Reinstall ViaVoice from CD.
2) Update to the latest version (using the patch downloadable from Nuance's website).
3) Replace the “temp” and “users” folders (in the "ViaVoice" folder at the upper level of your home directory) by a previous copy thereof. When I say previous copy, I mean a copy from when ViaVoice was still working properly, e.g. a copy from when it was running under Tiger.
As I said, I've gotten ViaVoice to survive several system updates by following the above steps. To my knowledge, the last step is critical since it saves you from having to reconfigure ViaVoice under the new operating system (in this case Leopard). I suspect that ViaVoice is crashing on your system because it's trying to start some module of the SetUpAssistant that is incompatible with Leopard (as many are). If you instead use old copies of the "temp" and "users" folders (from the previous system), then ViaVoice doesn't have to go through the initial "registration" process; ViaVoice doesn't need the SetUpAssistant; and all is (more or less) fine.
Good luck!
BTW, to my knowledge, Dictate only runs on Intel Macs. It thus won't run on a G4 iBook, just as it won't run on my PowerBook G4.

Performance problem with Mavericks.

Performance problem with Mavericks. My Mac is extremly slow after upgrading to Mavericks. What can i do to solve that?

If you are still experiencing slow down issues, it maybe because of a few other reasons.
Our experience with OS X upgrades, and Mavericks is no exception, is that users have installed a combination of third party software and/or hardware that is incompatible and/or is outdated that causes many negative performance issues when upgrading to a new OS X version.
Your Mac's hard drive maybe getting full.
Do you run any antivirus software on your Mac? Commercial Antivirus software can slow down and negatively impact the normal operation of OS X.
Do you have apps like MacKeeper or any other maintenance apps like CleanMyMac 1 or 2, TuneUpMyMac or anything like these apps, installed on your Mac? These types of apps, while they appear to be helpful, can do too good a job of data "cleanup" causing the potential to do serious data corruption or data deletion and render a perfectly running OS completely dead and useless leaving you with a frozen, non-functional Mac.
Your Mac may have way too many applications launching at startup/login.
Your Mac may have old, non-updated or incompatible software installed.
Your Mac could have incompatible or outdated web browser extensions, plugins or add-ons.
Your Mac could have connected third party hardware that needs updated device drivers.
It would help us to help you if we could have some more technical info about your iMac.

Problem with clob_write under client 9.2.0.6: UnsatisfiedLinkError

Hi all,
I'm running Oracle client 9.2.0.4 on Windows XP and Java 1.4.1_3.
Writing or reading clob's works pretty well.
As i tried to update to Oracle client 9.2.0.6, i got the error
Communication failed: java.lang.UnsatisfiedLinkError: clob_write when i tried to write a clob. The same error appears when i tried to read a clob.
Is there a specific problem with clobs under this client?
All other JDBC operations work as good as before.
Thanks.

Here is another hint.
In your classpath, use the jdbc driver that's under your oracle installation to which you are trying to connect to (ie, <ORACLE_HOME>\ora92\jdbc\lib\ojdbc14.jar).
I had the same problem in 9.2.0.6 and its gone when I replaced the ojdbc14.jar. I copied the ..\ora92\jdbc\lib\ojdbc14.jar to my java client program's classpath, and ran the java client without getting the UnsatisfiedLinkError.
It looks like the ocijdbc9.dll under ora92\bin has to match correctly with the jdbc drivers you would be using. I got this idea from this link:

Performance problem with Orcacle / Crystal reports 8.5 / ASP

Hi,
I have a performance problem with reports running crystal reports 8.5 with oracle databases.
Fetching data appears to be slow. Oracle trace reports (tkprof) shows that fetchsize=1.
Fetchsize in Oracle ODBC is 15 (default).
How can I update te fetchsize in crystal reports?
I would appreciate any help.

Performance problem with ojdbc14.jar

Hi,
We are having performance problem with ojdbc14.jar in selecting and updating (batch updates) entries in a table. The queries are taking minutes to execute. The same java code works fine with classes12.zip ans queries taking sub seconds to execute.
We have Oracle 9.2.0.5 Database Server and I have downloaded the ojdbc14.jar from Oracle site for the same. Tried executing the java code from windows 2000, Sun Solaris and Opteron machines and having the same problem.
Does any one know a solution to this problem? I also tried ojdbc14.jar meant for Oracle 10g, that did not help.
Please help.
Thanks
Yuva

My code is doing some thing which might be working well with classes12.zip and which does not work well with ojdbc14.jar? Any general suggestions to make the code better, especially for batch updates.
But for selecting a row from the table, I am using index columns in the where cluase. In the code using PreparedStatement, setting all the reuired fields. Here is the code. We have a huge index with 14 fields!!. All the parameters are for where clause.
if(longCallPStmt == null) {
longCallPStmt = conn.prepareStatement(longCallQuery);
log(Level.FINE, "CdrAggLoader: Loading tcdragg entry for "
+GeneralUtility.formatDate(cdrAgg.time_hour, "MM/dd/yy HH"));
longCallPStmt.clearParameters();
longCallPStmt.setInt(1, cdrAgg.iintrunkgroupid);
longCallPStmt.setInt(2, cdrAgg.iouttrunkgroupid);
longCallPStmt.setInt(3, cdrAgg.iintrunkgroupnumber);
longCallPStmt.setInt(4, cdrAgg.iouttrunkgroupnumber);
longCallPStmt.setInt(5, cdrAgg.istateregionid);
longCallPStmt.setTimestamp(6, cdrAgg.time_hour);
longCallPStmt.setInt(7, cdrAgg.icalltreatmentcode);
longCallPStmt.setInt(8, cdrAgg.icompletioncode);
longCallPStmt.setInt(9, cdrAgg.bcallcompleted);
longCallPStmt.setInt(10, cdrAgg.itodid);
longCallPStmt.setInt(11, cdrAgg.iasktodid);
longCallPStmt.setInt(12, cdrAgg.ibidtodid);
longCallPStmt.setInt(13, cdrAgg.iaskzoneid);
longCallPStmt.setInt(14, cdrAgg.ibidzoneid);
rs = longCallPStmt.executeQuery();
if(rs.next()) {
cdr_agg = new CdrAgg(
rs.getInt(1),
rs.getInt(2),
rs.getInt(3),
rs.getInt(4),
rs.getInt(5),
rs.getTimestamp(6),
rs.getInt(7),
rs.getInt(8),
rs.getInt(9),
rs.getInt(10),
rs.getInt(11),
rs.getInt(12),
rs.getInt(13),
rs.getInt(14),
rs.getInt(15),
rs.getInt(16)
}//if
end_time = System.currentTimeMillis();
log(Level.INFO, "CdrAggLoader: Loaded "+((cdr_agg==null)?0:1) + " "
+ GeneralUtility.formatDate(cdrAgg.time_hour, "MM/dd/yy HH")
+" tcdragg entry in "+(end_time - start_time)+" msecs");
} finally {
GeneralUtility.closeResultSet(rs);
GeneralUtility.closeStatement(pstmt);
Why that code works well for classes12.zip (comes back in around 10 msec) and not for ojdbc14.jar (comes back in 6-7 minutes)?
Please advise.

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?
