Information On The Performance
On the mac mini does a 2gb ram and 160gb hdd have enough power to handle everyday tasking like much and editing certain thing's and good for everyday use....
Plus Can I Hook This Monitor To The Mac Mini
http://www.newegg.com/Product/Product.aspx?Item=N82E16824112018
let me no please on the q's I askd
The base configuration works fine for every day things. You do not say what kind of editing. If you are working with Pro apps then you would be better off maxing the RAM to 4 GB.
That display should work fine with the Mac mini. The mini ships with an Apple mini-DVI to DVI adapter, so you could get a DVI to DVI cable and use the display's DVI port. Or you could get a DVI to HDMI cable and use the HDMI port.
Neither of the mini's video ports; mini-DVI or mini-DisplayPort carry an audio signal.

I find information about the performance of the ATG scenario engine.
Hi all,
It is a big point that I can release a business user directly by using a scenario of the ATG.
It is the strongest that I can use the information that tracked a site for the element of the scenario.
I almost collect the tracking information of the site for the site business in Japan.
However, it is the present conditions to use only the analysis of the count level.
I want to reclaim the world of totally new digital marketing in Japan.
It is necessary to release many scenarios to realize 'one to one marketing '.
However, such as the performance there is a question.
At first do you know the example that you use a scenario positively, and realizes an offer and recommend?
In addition, do you know which part of the sizing is important when you come true?
Regards,
hirofumiATG scenario engine is one of the feature that ATG provides for a personalised user experience, but the major limitation of scenario is it is event driven, you need to design your ecommerce application in such a way that you have to identify the possible events anddecide on appropriate actions. This will help in very few scenarios but a larger ecommerce application concerns it is very limited.
--At first do you know the example that you use a scenario positively, and realizes an offer and recommend?
This will be very difficult to achieve using a scenario, you can display some basic promotions to the customer but not a real recommendation. First to remember that scenario is not a recommendation engine.
Also this will not useful in case of anonymous customer since tracking anonymous customer behaviour is extremely difficult without a proper recommendation engine. either you have to custom build or go with a third party recommendation engine.

How to improve the performance of General information in MSS
HI,
We are facing with critical performance issue in General information screen of MSS.
For one employee number of subordinates are more than 3500 and because of this no of database hits for fetching all the records are more than 20,000 and each database hit is taking some time and overall time for fetching all the records is around 2 minutes which is not acceptable.
so we want to cut down the number of hierarchy levels shown to the manager or by keeping the same number of levels how to increase the performance .
Any inputs will be highly appreciated and rewarded with points for sure
Bala DuvvuriHi,
We have problem in performance because when we call General information screen for managers in MSS it reads the data from HRP1001 and if manager is having more data then it will take time.
we rectified this problem by creating an index that caches all the users who have more number of objects .
we created a job that creates index and execute that every day -
Where to find the performance counter information?
Code:

var totalOperationsCounter = new PerformanceCounter(
"MyCategory",
"# operations executed",

var operationPerSecondCounter = new PerformanceCounter(
"MyCategory",
"# operations / sec",
false);
totalOperationsCounter.Increment();
operationPerSecondCounter.Increment();
private static bool CreatePerformanceCounters()

return true;
return false;
After running it, it displays two line information on the screen. But where is the location to store these information? I want to look at it.Hello ardmore,
>>After running it, it displays two line information on the screen. But where is the location to store these information? I want to look at it.
You could performance counter monitor:
http://technet.microsoft.com/en-us/library/cc749249.aspx
Or see it in the Visual Studio directly:
In the Server Explore of Visual Studio, expand the Servers, find Performance Counters, you could see the MyCategory counter and other system counters:

Just to give an example, Microsoft IIS webserver provides the
performance counters, which one can read from registry using
APIs provided by Microsoft from a C/C++ program and get all the
performance related data ... r some similar interfaces
provided by iPlanet webserver ???The spell checked version...
I really appreciate the replies. I have looked into RMI and think it might fit the bill, ,BUT, let me clarify a bit and see if there are any other ideas floating around out there.
A user, using a web interface on machine A will click the , "I want my file" button. This flags the DB to create a file for that user. I will have multiple daemons running on other machines B,C,D whose sole job is to check the db, compile the file (This is the part that takes huge overhead so I wanted it distributed), then write the file. The trick is the file needs to be written to machine A. So I figure, using RMI, I can write a simple "write this file" object that will accept a byte stream or byte array, and a correct path to write to. Does this sound like a good methodology?
I've never done anything like this so I am really shooting in the dark.
Thanks again for the posts.

Re: How to Improve the performance on Rollup of Aggregates for PCA Infocube
Hi BW Guru's,
I have unresolved issue and our team is still working on it.
I have already posted several questions on this but not clear on how to reduce the time on Rollup of Aggregates process.
I have requested for OSS note and searching myself but still could not found.
Finally i have executed one of the cube in RSRV with the database selection
"Database indexes of an InfoCube and its aggregates" and got warning messages i was tried to correct the error and executed once again but still i found warning message. and the error message are as follows: (this is only for one info cube we got 6 info cubes i am executing one by one).
ORACLE: Index /BI0/IACCOUNT~0 has possibly degenerated
ORACLE: Index /BI0/IPROFIT_CTR~0 has possibly degenerated
ORACLE: Index /BI0/SREQUID~0 has possibly degenerated
ORACLE: Index /BIC/D1001072~010 has possibly degenerated
ORACLE: Index /BIC/D1001132~010 has possibly degenerated
ORACLE: Index /BIC/D1001212~010 has possibly degenerated

ORACLE: Index /BIC/QGMAPGP1~0 has possibly degenerated
ORACLE: Index /BIC/QGMAPPC2~0 has possibly degenerated
ORACLE: Index /BIC/SGMAPGP1~0 has possibly degenerated
i don't know how to move further on this can any one tell me how to tackle this problem to increase the performance on Rollup of Aggregates (PCA Info cubes).
every time i use to create index and statistics regularly to improve the performance it will work for couple of days and again the performance of the rollup of aggregates come down gradually.
Thanks and Regards,
Venkathi,
check in a sql client the sql created by Bi and the query that you use directy from your physical layer...
The time between these 2 must be 2-3 seconds,otherwise you have problems.(these seconds are for scripts that needed by Bi)
If you use "like" in your sql then forget indexes....
For more informations about indexes check google or your Dba .
Last, i mentioned that materialize view is not perfect,it help a lot..so why not try to split it to smaller ones....
ex...
logiacal dimensions
year-half-day
company-department
fact
quantity
instead of making one...make 3,
year - department - quantity
half - department - quantity
day - department - quantity
and add them as datasource and assign them the appropriate logical level at bussiness layer in administrator...
Do you use partioning functionality???
i hope i helped....

"n435991ABAP provides few tools to analyse the perfomance of the objects, which was developed by us.
Run time analysis transaction SE30
This transaction gives all the analysis of an ABAP program with respect to the database and the non-database processing.
SQL Trace transaction ST05
by using this tool we can analyse the perfomance issues related to DATABASE calls.
Perfomance Techniques for improve the perfomance of the object.
1) ABAP/4 programs can take a very long time to execute, and can make other processes have to wait before executing. Here are some tips to speed up your programs and reduce the load your programs put on the system:
2) Use the GET RUN TIME command to help evaluate performance. It's hard to know whether that optimization technique REALLY helps unless you test it out.
3) Using this tool can help you know what is effective, under what kinds of conditions. The GET RUN TIME has problems under multiple CPUs, so you should use it to test small pieces of your program, rather than the whole program.
4) Generally, try to reduce I/O first, then memory, then CPU activity. I/O operations that read/write to hard disk are always the most expensive operations. Memory, if not controlled, may have to be written to swap space on the hard disk, which therefore increases your I/O read/writes to disk. CPU activity can be reduced by careful program design, and by using commands such as SUM (SQL) and COLLECT (ABAP/4).
5) Avoid 'SELECT *', especially in tables that have a lot of fields. Use SELECT A B C INTO instead, so that fields are only read if they are used. This can make a very big difference.
6) Field-groups can be useful for multi-level sorting and displaying. However, they write their data to the system's paging space, rather than to memory (internal tables use memory). For this reason, field-groups are only appropriate for processing large lists (e.g. over 50,000 records). If you have large lists, you should work with the systems administrator to decide the maximum amount of RAM your program should use, and from that, calculate how much space your lists will use. Then you can decide whether to write the data to memory or swap space.
Use as many table keys as possible in the WHERE part of your select statements.
7)Whenever possible, design the program to access a relatively constant number of records (for instance, if you only access the transactions for one month, then there probably will be a reasonable range, like 1200-1800, for the number of transactions inputted within that month). Then use a SELECT A B C INTO TABLE ITAB statement.
8) Get a good idea of how many records you will be accessing. Log into your productive system, and use SE80 -> Dictionary Objects (press Edit), enter the table name you want to see, and press Display. Go To Utilities -> Table Contents to query the table contents and see the number of records. This is extremely useful in optimizing a program's memory allocation.
9) Try to make the user interface such that the program gradually unfolds more information to the user, rather than giving a huge list of information all at once to the user.
10) Declare your internal tables using OCCURS NUM_RECS, where NUM_RECS is the number of records you expect to be accessing. If the number of records exceeds NUM_RECS, the data will be kept in swap space (not memory).
11) Use SELECT A B C INTO TABLE ITAB whenever possible. This will read all of the records into the itab in one operation, rather than repeated operations that result from a SELECT A B C INTO ITAB... ENDSELECT statement. Make sure that ITAB is declared with OCCURS NUM_RECS, where NUM_RECS is the number of records you expect to access.
12) If the number of records you are reading is constantly growing, you may be able to break it into chunks of relatively constant size. For instance, if you have to read all records from 1991 to present, you can break it into quarters, and read all records one quarter at a time. This will reduce I/O operations. Test extensively with GET RUN TIME when using this method.
13) Know how to use the 'collect' command. It can be very efficient.
14) Use the SELECT SINGLE command whenever possible.
15) Many tables contain totals fields (such as monthly expense totals). Use these avoid wasting resources by calculating a total that has already been calculated and stored.
Some tips:
1) Use joins where possible as redundant data is not fetched.
2) Use select single where ever possible.
3) Calling methods of a global class is faster than calling function modules.
4) Use constants instead of literals
5) Use WHILE instead of a DO-EXIT-ENDDO.
6) Unnecessary MOVEs should be avoided by using the explicit work area operations

How to measure the performance of sql query?
Hi Experts,
How to measure the performance, efficiency and cpu cost of a sql query?
What are all the measures available for an sql query?
How to identify i am writing optimal query?
I am using Oracle 9i...
It ll be useful for me to write efficient query....
Thanks & Regardspsram wrote:

I am using Oracle 9i... You might want to start with a feature of SQL*Plus: The AUTOTRACE (TRACEONLY) option which executes your statement, fetches all records (if there is something to fetch) and shows you some basic statistics information, which include the number of logical I/Os performed, number of sorts etc.
This gives you an indication of the effectiveness of your statement, so that can check how many logical I/Os (and physical reads) had to be performed.
Note however that there are more things to consider, as you've already mentioned: The CPU bit is not included in these statistics, and the work performed by SQL workareas (e.g. by hash joins) is also credited only very limited (number of sorts), but e.g. it doesn't cover any writes to temporary segments due to sort or hash operations spilling to disk etc.
You can use the following approach to get a deeper understanding of the operations performed by each row source:
alter session set statistics_level=all;
alter session set timed_statistics = true;
select /* findme */ ... <your query here>
SELECT
SUBSTR(LPAD(' ',DEPTH - 1)||OPERATION||' '||OBJECT_NAME,1,40) OPERATION,
OBJECT_NAME,
CARDINALITY,
LAST_OUTPUT_ROWS,
LAST_CR_BUFFER_GETS,
LAST_DISK_READS,
LAST_DISK_WRITES,
FROM V$SQL_PLAN_STATISTICS_ALL P,
(SELECT *
FROM (SELECT *
FROM V$SQL
WHERE SQL_TEXT LIKE '%findme%'
AND SQL_TEXT NOT LIKE '%V$SQL%'
AND PARSING_USER_ID = SYS_CONTEXT('USERENV','CURRENT_USERID')
ORDER BY LAST_LOAD_TIME DESC)
WHERE ROWNUM < 2) S
WHERE S.HASH_VALUE = P.HASH_VALUE
AND S.CHILD_NUMBER = P.CHILD_NUMBER
ORDER BY ID
/Check the V$SQL_PLAN_STATISTICS_ALL view for more statistics available. In 10g there is a convenient function DBMS_XPLAN.DISPLAY_CURSOR which can show this information with a single call, but in 9i you need to do it yourself.
Note that "statistics_level=all" adds a significant overhead to the processing, so use with care and only when required:

Need Help to see why the performance is not good
Hi,
We have an application that all process are developed in PL/SQL on Oracle 9i Database :
Oracle9i Enterprise Edition Release 9.2.0.6.0 - 64bit Production
PL/SQL Release 9.2.0.6.0 - Production
Why I have created this package. the application is a production management on chemical industries. I need to sometimes trace the Manufacturing order execution to eventually answer some incoherent data. If I analyze directly the data in the Table is not always responding because the origin of problem can be provide of some execution that perform some calculation.
In the procedure or function a use my package PAC_LOG_ERROR.PUT_LINE(xxxxxx) to save the information. This command save the information in the memory before. At the end of the procedure or function a perform the insert with the COMMIT calling PAC_LOG_ERROR.LOGS or PAC_LOG_ERROR.ERRORS on the catch exception.
This package is always call. On each routines performed I execute it. In the trace log of the database we have see a problem we the procedure GET_PROC_NAME in the package. We have identify that is called more that 800x and increase the performance. Who increase is this select command :
SELECT * INTO SOURCE_TEXT
FROM (SELECT TEXT FROM all_source
WHERE OWNER = SOURCE_OWNER AND
NAME=SOURCE_NAME AND
TYPE IN ('PROCEDURE','FUNCTION','PACKAGE BODY') AND
LINE <= SOURCE_LINE AND SUBSTR(TRIM(TEXT),1,9) IN ('PROCEDURE','FUNCTION ')
ORDER BY LINE DESC)
WHERE ROWNUM = 1;I use it to get the procedure or function name where my log proc is called. I now that I can pass in parameters, but I have think to use an automatic method, that can help to not have some problem with others developer team to make a copy/past and not update the parameters. Because the Log info is read by the Help Desk and if we have an error on the information, it not a good help.
COULD YOU PLEASE HELP ME TO OPTIMIZE OR SAID THE BETTER METHOD TO DO IT ?

Hello everybody,
First to introduce myself. My name is Ivan and I recently started learning SQL and PL/SQL. So don't go hard on me. :)
Now let's jump to the problem. What we have there is a table (big one, but we'll need only a few fields) with some information about calls. It is called table1. There is also another one, absolutely the same structure, which is empty and we have to transfer the records from the first one.
The shorter calls (less than 30 minutes) have segmentID = 'C1'.
The longer calls (more than 30 minutes) are recorded as more than one record (1 for every 30 minutes). The first record (first 30 minutes of the call) has segmentID = 'C21'. It is the first so we have only one of these for every different call. Then we have the next (middle) parts of the call, which have segmentID = 'C22'. We can have more than 1 middle part and again the maximum minutes in each is 30 minutes. Then we have the last part (again max 30 minutes) with segmentID = 'C23'. As with the first one we can have only one last part.
So far, so good. Now we need to insert these call records into the second table. The C1 are easy - one record = one call. But the partial ones we need to combine so they become one whole call. This means that we have to take one of the first parts (C21), find if there is a middle part (C22) with the same calling/called numbers and with 30 minutes difference in date/time, then search again if there is another C22 and so on. And last we have to search for the last part of the call (C23). In the course of these searches we sum the duration of each part so we can have the duration of the whole call at the end. Then we are ready to insert it in the new table as a single record, just with new duration.
But here comes the problem with my code... The table has A LOT of records and this solution, despite the fact that it works (at least in the tests I've made so far), it's REALLY slow.
As I said I'm new to PL/SQL and I know that this solution is really newbish, but I can't find another way of doing this.
So I decided to come here and ask you for some tips on how to improve the performance of this.
I think you are getting confused already, so I'm just going to put some comments in the code.
I know it's not a procedure as it stands now, but it will be once I create a better code. I don't think it matters for now.

It's my first post here so hope this is the right sub-forum.
I tried to explain everything as deep as possible (sorry if it's too long) and I kinda think that the code got somehow hard to read with all these comments. If you want I can remove them.
I know I'm still missing a lot of knowledge so every help is really appreciated.
Thank you very much in advance!Atiel wrote:
Thanks for the suggestion but the thing is that segmentID must stay the same for all. The data in this field is just to tell us if this is a record of complete call (C1) or a partial record of a call(C21, C22, C23). So in table2 as every record will be a complete call the segmentID must be C1 for all.Well that's not a problem. You just hard code 'C1' instead of applying the row number as I was doing:

Another thing is that, as I said above, the actual table has 120 fields. Do I have to list them all manually if I use something similar?If that's what you need, then yes you would have to list them. You only get data if you tell it you want it. ;)
Of course if you are taking the start_date_of_call, callingnumber and callednumber as the 'key' to the record, then you could join the results of the above back to the original table1 and pull out the rest of the columns that way...

SQL>Of course this is pulling back the additional columns for the record that matches the start_date_of_call for that calling/called number pair, so if the values differed from row to row within the calling/called number pair you may need to aggregate those (take the minimum/maximum etc. as required) as part of the first query. If the values are known to be the same across all records in the group then you can just pick them up from the join to the original table as I coded in the above example (only in my example the data was different across all rows). -
How to optimize the performance of crystal report?
Hi,
-I have to design a crystal report with best possible optimization. Optimization is main concern since report will run against 1-2 million data set. Though I am using parameter to fetch only the required data, required data can go till 1 million records.
-Based on the input passed by the user I have to group the data in report. And for each selected parameter the Detail section I am printing is different. For example:-If user selects store then detail section is different and if user select Host then detail section will be different.
-Report can be grouped by Time Field also. So to full fill this requirement I would have to create a sub report since other parameters are of string type and can be used in one formula to get parameter based grouping in report. However If I try to return Time filed from the same formula I get the errors the "Return type should be of String typeu201D. This forces me to create sub report for Time based grouping. If user selects Time Field to be grouped on, all the information in the main report gets suppressed and only the sub report gets printed.
If user select store, Host and User in parameter to be grouped on, sub report gets suppressed.
Now with the above mentioned points I tried to optimize the report in following way.
-Printing 1 million records in the report does not make sense; hence we wanted to show the summary of all the records in chart section but wanted to print just 5000 records in detailed section. Suppressing detailed section after 5000 records does not help much since suppressing just saves the time in printing and does not limit the number of records to be fetched from the DB.I have a subreport also so it fetches the data 2 times from the DB hence makes the performance of the report worse.
To solve this problem I used command object and put the charts in the subreport and detail in main report.
In main report's Command Object I limited the number to records to be fetched from the DB to 5000 using rownum<5000 but in subreport's Command Object I did not set any limit in the query but I am doing all my aggregation in SQL which means do summary operation in DB and get only summarized data from DB.
-To solve section problem I am using Template object (new feature added in CR 2008).In which I am returning the field based on the "Group By" parameter selected by user.
-For time Field I have created two sub reports, one for chart and other one for details in the same way described in point one(Printing 1 million recordsu2026u2026).
After implementing these points my crystal reports performance improved drastically. The report that was taking 24 minute to come back now taking only 2 minutes.
However I want my report to come back with one minute. It returns if I remove the sub reports for Time Based Grouping but I can not do so.
My questions here are,
-Can I stop Subreport from fetching the data from DB if itu2019s suppressed?
-I believe using Conditional Template Object is a better option rather than having multiple detailed sections to print the data for a selected Group. However any suggestion here to improve the performance will be appreciable.
-since crystal report does not provide any option to limit the number of records to be fetched from DB, I am forced to use command object with rownum in where condition.
Please let me know about other option(s) to get this done...If there is any.
I am using Crystal report 2008.And we have developed our application the use JRC to export crystal report in PDF.

Edited by: Amrita Singh on May 12, 2009 11:36 AM1) I have to design a crystal report with best possible optimization. Optimization is main concern since report will run against 1-2 million data set. Though I am using parameter to fetch only the required data, required data can go till 1 million records.
2) Based on the input passed by the user I have to group the data in report. And for each selected parameter the Detail section I am printing is different. For example:-If user selects store then detail section is different and if user select Host then detail section will be different.
3) Report can be grouped by Time Field also. So to full fill this requirement I would have to create a sub report since other parameters are of string type and can be used in one formula to get parameter based grouping in report. However If I try to return Time filed from the same formula I get the errors the "Return type should be of String typeu201D. This forces me to create sub report for Time based grouping. If user selects Time Field to be grouped on, all the information in the main report gets suppressed and only the sub report gets printed.
If user select store, Host and User in parameter to be grouped on, sub report gets suppressed.
Now with the above mentioned points I tried to optimize the report in following way.
1) Printing 1 million records in the report does not make sense; hence we wanted to show the summary of all the records in chart section but wanted to print just 5000 records in detailed section. Suppressing detailed section after 5000 records does not help much since suppressing just saves the time in printing and does not limit the number of records to be fetched from the DB.I have a subreport also so it fetches the data 2 times from the DB hence makes the performance of the report worse.
To solve this problem I used command object and put the charts in the subreport and detail in main report.
In main report's Command Object I limited the number to records to be fetched from the DB to 5000 using rownum<5000 but in subreport's Command Object I did not set any limit in the query but I am doing all my aggregation in SQL which means do summary operation in DB and get only summarized data from DB.
2)To solve section problem I am using Template object (new feature added in CR 2008).In which I am returning the field based on the "Group By" parameter selected by user.

Kappy's Personal Suggestions About OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utility is: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption. Drive Genius provides additional tools not found in Disk Warrior for defragmentation of older drives, disk repair, disk scans, formatting, partitioning, disk copy, and benchmarking.
Four outstanding sources of information on Mac maintenance are:
1. OS X Maintenance - MacAttorney.
2. Mac maintenance Quick Assist
3. Maintaining Mac OS X
4. Mac Maintenance Guide
Periodic Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) See Mac OS X- About background maintenance tasks. If you are running Leopard or later these tasks are run automatically, so there is no need to use any third-party software to force running these tasks.
If you are using a pre-Leopard version of OS X, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced after Tiger. (These utilities have limited or no functionality with Snow Leopard, Lion, or Mountain Lion and should not be installed.)
Defragmentation
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive except when trying to install Boot Camp on a fragmented drive. But you don't need to buy third-party software. All you need is a spare external hard drive and Carbon Copy Cloner.
Cheap and Easy Defragmentation
You will have to backup your OS X partition to an external drive, boot from the external drive, use Disk Utility to repartition and reformat your hard drive back to a single volume, then restore your backup to the internal hard drive. You will use Carbon Copy Cloner to create the backup and to restore it.
1. Get an empty external hard drive and clone your internal drive to the
external one.
2. Boot from the external hard drive.
3. Erase the internal hard drive.
4. Restore the external clone to the internal hard drive.
Clone the internal drive to the external drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not depressed or is ghosted.
5. Click on the Clone button.
Destination means the external backup drive. Source means the internal startup drive.
Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive and click on the upward pointing arrow button.
After startup do the following:
Erase internal hard drive
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your internal hard drive (this is the entry with the
mfgr.'s ID and size) from the left side list. Note the SMART status of the
drive in DU's status area. If it does not say "Verified" then the drive is
failing or has failed and will need replacing. SMART info will not be
reported on external drives. Otherwise, click on the Partition tab in the
DU main window.
3. Under the Volume Scheme heading set the number of partitions from the
drop down menu to one. Set the format type to Mac OS Extended
(Journaled.) Click on the Options button, set the partition scheme to
GUID then click on the OK button. Click on the Partition button and wait
until the process has completed.
Restore the clone to the internal hard drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not selected or is ghosted.
5. Click on the Clone button.
Destination means the internal hard drive. Source means the external startup drive.
Note that the Source and Destination drives are swapped for this last procedure.
Malware Protection
As for malware protection there are few if any such animals affecting OS X. Starting with Lion Apple has included built-in malware protection that is automatically updated as necessary.
Helpful Links Regarding Malware Protection:
1. Mac Malware Guide.
2. Detecting and avoiding malware and spyware
3. Macintosh Virus Guide
For general anti-virus protection I recommend only using ClamXav, but it is not necessary if you are keeping your computer's operating system software up to date. You should avoid any other third-party software advertised as providing anti-malware/virus protection. They are not required and could cause the performance of your computer to drop.
Cache Clearing
I recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, Mountain Lion Cache Cleaner 7.0.9, Maintenance 1.6.8, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc. Corrupted cache files can cause slowness, kernel panics, and other issues. Although this is not a frequent nor a recurring problem, when it does happen there are tools such as those above to fix the problem.
If you are using Snow Leopard or earlier, then for emergency cleaning install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. (AppleJack works with Snow Leopard or earlier.)
Installing System Updates or Upgrades
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Backup and Restore
Having a backup and restore strategy is one of the most important things you can do to maintain your computer. Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner.
2. Deja Vu
3. SuperDuper!
4. Synk Pro
5. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance and backup and restore.
Always have a current backup before performing any system updates or upgrades.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity or 20 GBs, whichever is greater, as free space. Avoid installing utilities that rely on Haxies, SIMBL, or that alter the OS appearance, add features you will rarely if ever need, etc. The more extras you install the greater the probability of having problems. If you install software be sure you know how to uninstall it. Avoid installing multiple new software at the same time. Install one at a time and use it for a while to be sure it's compatible.

Windows 7 64-bit with MS Outlook 2010. I've seen this now probably 10 times. When I first installed iTunes, I selected:
Preferences -> Devices -> "Prevent iPhonse, iPhones and iPads from syncing automatically".
and on my iPhone, I selected:
Info -> Sync Contacts with: Outlook.
Info -> Sync Calendars with: Outlook
Info -> Other -> Sync notes with: Outlook
This works great, and the settings stick. As soon as apple releases any new version (even minor) of iTunes and I install, I immediately receive: "...the information on the iphone is synced with another user account", and have to merge my calendar and contacts, but then once I get into iTunes, I find that ALL of the above settings (prevent syncing, sync calendar, contacts, notes) get reset and are turned off! I am running as a user account with Admin privaleges, but I don't right-click -> "Run as administrator" when I perform the iTunes update.
To reiterate, once I change the settings back, things work normally until the next iTunes update at which it gives me that sync error, and resets my sync options.
Any idea? Thanks!
-BrianIs someone else using the PC and iTunes?
Create another user for the PC with your name, and try syncing that way.
This way it wont conflic with the other user.
