IPhone Performance Tuning Using Shark

Hi, I'm trying to do some performance tuning and am having some trouble using Shark.
*Problem #1*: No matter what configuration I choose ( debug, release, simulator, device ) the "Shark" menu item under "Run" in XCode is greyed out. How do I enable this feature so I can run my application using Shark through XCode?
*Problem #2*: I've been able to run Shark on it's own while my iPhone simulator is running and have tried to capture my application. However, for some reason my application name "TestApp" shows up multiple times in the drop down in Shark when selecting which process to monitor. They all have the "TestApp" and most of them have a number after it such as 94452. Any ideas on why this happens and which one is the process I should choose?
*Problem #3*: I've tried simply selecting one of the four or five "TestApp" processes from the Shark drop down and running it. It does capture information and gives me the results, however most of the symbols are missing even though my project has "Gererate Debug Symbols" check box checked in the project settings. Is there something else I need to do in order to get all symbols to show up?
My hope is that by fixing problem #1, it will automatically fix problems #2 and #3.
Any help would be great! Thanks!

where is the original version of the executable on the filesystem? i can't seem to find it.
Look in your project's folder. It's in the "build" folder, in another folder probably named "Debug-iphoneos". When you choose the right file, (the executable, not the ".dSYM" file), the bottom of the file panel will fill out in black with information. If you choose the wrong one (like the simulator executable), the information in the file open panel will be red and you'll get an error message.

Issue in switching on performance tuning using /ron & /roff

Hi Experts,
    When I am in a break point of a program, if I switch on performance trace using the ok code "/ron", it throws the error "Particular units is not switched on". I know that option is available in SE30 variant. But how to swich on that, if we start trace from programs debug screen. Kindly help me out. I would like to trace for a particular subroutine. How to do that.
Thanks and regards,
Venkat.

Hi,
   ST12 transaction is no more in recent SAP systems.
   In SE30, we create the variant and we can enable the particular units.
   But the question is, when I am in debugging mode of a report, I have to activate performance trace. It is done by executing the OK code "/ron" in debugging mode. But , if I execute that ok code, it says, I have not selected particular units. I have not even started execution from SE30(since it will trace from the starting). How can I enable it?
Thanks and regards,
Venkat.

How can I print to my HP OfficeJet 6500 Wireless Printer from my iPhone 4S which used to work before AirPrint printers were even available? (running Mac Lion OS, all software and HP sw updates are all performed)

How can I print to my HP OfficeJet 6500 Wireless Printer from my iPhone 4S which used to work (on prior iPhones) before AirPrint printers were even available? (running Mac Lion OS, all software and HP sw updates are all performed)
I don't get it, I read one post about why would we have to buy an AirPrint Printer when we have used the "print to a wifi printer" just fine in the past? Yes I feel that's exactly what's happening to me now too. I want to print from my iPhone and iPad to my WiFi Printer which is also now connected to my Airport Express WiFi network just fine. No problems.

Very glad you added that bit of information because I see different problems similar to this. I want to share with them what you did and hopefully you not only fixed your specific problem but you can lend some more advice to others with problems like this. Thanks!
Don't forgot to say thanks by giving "Kudos" if I helped solve your problem.

Can i use "Oracle Database 12c: Performance Management and Tuning " training for getting certification on "Oracle Database 11g: Performance Tuning 1Z0-054"

i have taken "Oracle Database 12c: Performance Management and Tuning new" training from oracle university. Now i would like to get certified on "Oracle Database 11g: Performance Tuning 1Z0-054" exam. Is it possible ?

I essentially endorse and refer you to Matthews' and John's post above.
I would differ with slightly with Matthew because my guess is you would often be able to use like for like 12c training for an 11g certification ( I believe there are precedents). BEFORE ANYONE ASKS THE OTHER WAY DOESN'T HAPPEN.
.... but totally concur with Matthew you would ill advised to procede on that basis without one of:
- This being advertised as possible on the website : e.g. https://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=654&get_params=p_id:169 ... option 2 show courses.
- Confirmation from Brandye
- Confirmation from an Oracle Certification Support Web Ticket ( http://education.oracle.com/pls/eval-eddap-dcd/OU_SUPPORT_OCP.home?p_source=OCP )
... The more common (and in my opinion usually better) way would be get your 11g DBA OCP ( or higher first) and then take the 1z0-054. I am almost certain they will accept your 12c course for the 11g DBA OCP.
If you are choosing the route of not being a 11g (or 12c ) DBA OCP first but are on option 2 and relying on the course for certification then the issue is more in the balance and you are even more strongly advised to get confirmation before proceding (remember if the rules need to be changed for you only then any profit out of the exam is lost).
In general my understanding is Oracle would prefer to encourage people to train on the latest version of product that is available for training and will prefer to avoid restrictions which would cause you to train at a lower version. ( This is simply my guess at Oracle University Policy ... personal opinion only).
Having said all I have said I'd encourage you to go with the advice of the earlier two posts.

Performance tuning of database using DBACOCKPIT

Hiii Experts,
I have installed new server with OS:- Windows server 2012 and DB:- Sybase ASE 15.07.
Now I want to perform performance tuning of SAP and Database, so for that I have configured
DBACOCKPIT but I could not change the parameter values so could you tell me how to change
parameter values and how to use DBACOCKPIT for performance tuning.
Thank you,
Regards,

If star transformation was not the cause of the slowness, of course it won't make it faster.
I bet you any number of other different hints will result in no change in performance.
This is like replacing gas tank on your car with a LARGER tank & filling it with more gasoline to make the car go faster.
The amount of gasoline is not a factor that limits the speed of your car.

Which tool is used for Oracle 11g performance tuning?

Hi all
I used statspack for 9i's performance tuning.
But with 11g R2 now I want to know which way are you using to do performance tuning?
Statspack? OSW? RDA? ADDM? Or other ways?
Thank you.

Standard troubleshooting...
Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
Remove all apps from Recently Used list...
- From any Home Screen, double tap the home button to bring up the Recents List
- Tap and hold any icon in this list until they wiggle
- Press the red to delete apps from this list.
- Press the home button twice when done.
If still a problem restore with your backup.
If still a problem restore as new, i.e. without your backup. See how it runs with nothing synced to it.
If still a problem, it's likely a hardware issue.

Abap Logic for performance tuning not working when using Internal tables

Hi,
I wrote this piece of code that is working correctly that is select SUM of cost from DSO where Plant is the same for Sales Items.
LOOP AT RESULT_PACKAGE INTO rp.
SELECT SUM( /N/S_STRDCOST ) FROM /N/ADSP_DPIT00 INTO
rp-/N/S_STRDCOST
WHERE /N42/S_SALESITEM = rp-/N42/S_ITEMID AND /N42/S_PLPLANT EQ
rp-/N42/S_SOURCE.
MODIFY RESULT_PACKAGE FROM rp.
Clear rp.
ENDLOOP.
Now I try to rewrite it for performance tunning using internal table but I am getting 0 values. can't figure out whats the problem and been struggling fixing it.
TYPES : begin of ty_DSO_TABLE,
         /N42/S_STRDCOST TYPE /N/ADSP_DSPC00-/N/S_STRDCOST,
         /N42/S_ITEMID TYPE /N/ADSP_DSPC00-/N/S_ITEMID,
       end of ty_DSO_TABLE.
DATA: it_DSO_TABLE type hashed table of ty_DSO_TABLE with unique key
/N/S_ITEMID,
     wa_DSO_TABLE type ty_DSO_TABLE.
Field-symbols: <rp> TYPE tys_TG_1.
LOOP AT RESULT_PACKAGE assigning <rp>.
clear wa_DSO_TABLE.
Read table IT_DSO_TABLE into wa_DSO_TABLE with table key /N/S_ITEMID
= <rp>-/N/S_ITEMID.
if sy-subrc ne 0.
      select SUM( /N/S_STRDCOST ) into CORRESPONDING
      FIELDS OF wa_DSO_TABLE from
      /N/ADSP_DPIT00 WHERE /N/S_SALESITEM = <rp>-/N/S_ITEMID AND
      /N/S_PLPLANT EQ <rp>-/N/S_SOURCE.
     if sy-subrc eq 0.
          <rp>-/N/S_STRDCOST = wa_DSO_TABLE-/N/S_STRDCOST.
     endif.
endif.
ENDLOOP.
Any idea whats wrong with the code
thanks

Hi Vaidya,
According to the code which you have written, there is no value in table IT_DSO_TABLE when you are trying to read the values.And after the read statement you have given a condition for sy-subrc. Hence the select statement is actually not even getting executed. *Also you have not assigned the final value back to the ResultPackage.*_
So Kindly correct your code as follows:
Data: wa_dso type ty_DSO_TABLE.
LOOP AT RESULT_PACKAGE assigning <rp>.
clear wa_DSO_TABLE.
select SUM( /N/S_STRDCOST ) into CORRESPONDING
FIELDS OF wa_DSO_TABLE from
/N/ADSP_DPIT00 WHERE /N/S_SALESITEM = <rp>-/N/S_ITEMID AND
/N/S_PLPLANT EQ <rp>-/N/S_SOURCE.
if sy-subrc eq 0.
<rp>-/N/S_STRDCOST = wa_DSO_TABLE-/N/S_STRDCOST.
MODIFY RESULT_PACKAGE FROM <rp>.
endif.
ENDLOOP.
Hope this helps you.

Report running for long time & performance tuning

Hi All,
(1). WebI report is running for long time.so what are the steps i need to check for it ?
(2). Can you tell me about performance tuning in BO ?
please help me.....
Thanks
Kumar

(1). WebI report is running for long time.so what are the steps i need to check for it ?
The first step is to see if the problem lies in the query on the data source or in webi itself. Depending on the data source there are different ways to extract the query and try to run it against the database. Which source does your report uses?
(2). Can you tell me about performance tuning in BO ?
I would recommend to start by reading the administrator's guide. There is a section about how to improve performance.

Oracle 11g Performance tuning approach ?

Hello Experts,
Is it the right forum to follow oracle performance tuning discussions ? If not, let me know what will be the forum to pick up some thread on this subject.
I am looking for performance tuning approach for oracle 11g. I learned there are some new items in 11g in this regard. For persons, who did tuning in earlier versions of Oracle,
what will be the best way adopt to 11 g?
I reviewed the 11g performance tuning guide, but I am looking for some white papers/blogs with case studies and practical approaches. I hope that you have used them.
What are the other sources to pick up some discussions?
Do you mind, share your thoughts?
Thanks in advance.

Performance tuning of BPEL processes in SOA Suite 11g

Hi,
We are working with a customer for performance tuning of SOA Suite 11g, one of the areas is to tune the BPEL processes. I am new to this and started out with stress testing Hello World process using SOAPUI tool. I would like help with the below topics -
1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
2. Do we need to run stress tests for every BPEL process deployed?
2. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
Thanks in advance!
Sritama

1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
You need
pay attention to:
java heap usage vs java heap capacity
java eden usage vs java eden capacity
JDBC pool initial connections vs JDBC pool capacity connections
if you are using linux: top
if you are using aix: topas
2. Do we need to run stress tests for every BPEL process deployed?
yes, you need test each BPEL. You can use "Jmeter" tool.
Download Jmeter from here: Apache JMeter - Apache JMeter&trade;
Other tools:
jstat
jstack
jps -v
Enterprise Manager
WebLogic Console
VisualVM
JRockit Mission Control
3. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
I recommend "Oracle SOA Suite 11g Performance Tuning Cookbook" http://www.amazon.com/Oracle-Suite-Performance-Tuning-Cookbook/dp/1849688842/ref=sr_1_1?ie=UTF8&qid=1378482031&sr=8-1&keywords=oracle+soa+suite+11g+performance+tuning+cookbook

(new?) performance problem using jDriver after a Sql Server 6.5 to 2000 conversion

Hi,
This is similar - yet different - to a few of the old postings about performance
problems with using jdbc drivers against Sql Server 7 & 2000.
Here's the situation:
I am running a standalone java application on a Solaris box using BEA's jdbc driver
to connect to a Sql Server database on another network. The application retrieves
data from the database through joins on several tables for approximately 40,000
unique ids. It then processes all of this data and produces a file. We tuned
the app so that the execution time for a single run through the application was
24 minutes running against Sql Server 6.5 with BEA's jdbc driver. After performing
a DBMS conversion to upgrade it to Sql Server 2000 I switched the jDriver to the
Sql Server 2000 version. I ran the app and got an alarming execution time of
5hrs 32 min. After some research, I found the problem with unicode and nvarchar/varchar
and set the "useVarChars" property to "true" on the driver. The execution time
for a single run through the application is now 56 minutes.
56 minutes compared to 5 1/2 hrs is an amazing improvement. However, it is still
over twice the execution time that I was seeing against the 6.5 database. Theoretically,
I should be able to switch out my jdbc driver and the DBMS conversion should be
invisible to my application. That would also mean that I should be seeing the
same execution times with both versions of the DBMS. Has anybody else seen a
simlar situation? Are there any other settings or fixes that I can put into place
to get my performance back down to what I was seeing with 6.5? I would rather
not have to go through and perform another round of performance tuning after having
already done this when the app was originally built.
thanks,
mike

Joe,
This was actually my next step. I replaced the BEA driver with
the MS driver and let it run through with out making any
configuration changes, just to see what happened. I got an
execution time of about 7 1/2 hrs (which was shocking). So,
(comparing apples to apples) while leaving the default unicode
property on, BEA ran faster than MS, 5 1/2 hrs to 7 1/2 hrs.
I then set the 'SendStringParametersAsUnicode' to 'false' on the
MS driver and ran another test. This time the application
executed in just over 24 minutes. The actual runtime was 24 min
16 sec, which is still ever so slightly above the actual runtime
against SS 6.5 which was 23 min 35 sec, but is twice as fast as the
56 minutes that BEA's driver was giving me.
I think that this is very interesting. I checked to make sure that
there were no outside factors that may have been influencing the
runtimes in either case, and there were none. Just to make sure,
I ran each driver again and got the same results. It sounds like
there are no known issues regarding this?
We have people looking into things on the DBMS side and I'm still
looking into things on my end, but so far none of us have found
anything. We'd like to continue using BEA's driver for the
support and the fact that we use Weblogic Server for all of our
online applications, but this new data might mean that I have to
switch drivers for this particular application.Thanks. No, there is no known issue, and if you put a packet sniffer
between the client and DBMS, you will probably not see any appreciable
difference in the content of the SQL sent be either driver. My suspicion is
that it involves the historical backward compatibility built in to the DBMS.
It must still handle several iterations of older applications, speaking obsolete
versions of the DBMS protocol, and expecting different DBMS behavior!
Our driver presents itself as a SQL7-level application, and may well be treated
differently than a newer one. This may include different query processing.
Because our driver is deprecated, it is unlikely that it will be changed in
future. We will certainly support you using the MS driver, and if you look
in the MS JDBC newsgroup, you'll see more answers from BEA folks than
from MS people!
Joe
>

Mike
The next test you should do, to isolate the issue, is to try another
JDBC driver.
MS provides a type-4 driver now, for free. If it is significantly faster,
it would be
interesting. However, it would still not isolate the problem, because
we still would
need to know what query plan is created by the DBMS, and why.
Joe Weinstein at BEA
PS: I can only tell you that our driver has not changed in it's semantic
function.
It essentially send SQL to the DBMS. It doesn't alter it.

Don't buy an iPhone if you use a Windows PC

iPhones are made to work with Mac computers. Your experience will be limited if you have a Windows PC. I want a phone that can stream longer home videos from the phone to the PC to send to family living in other states. The Apple program iPhoto will not work with Windows. I may be the only person on the planet who has read the 163-page iPhone 4 manual. Under the instructions for streaming video, it tells me that it cannot be done if I have a Windows computer. Yes, iTunes and Quick Time media players have Windows conversions, but so far iPhotos does not, and it is the only program used for sending longer home video from the phone to the computer.
The phone's memory allows me to email or text a 50 second video, but if I want a longer video, I have to stream it and I can’t because iPhoto is for Macs only. Word to the wise: If you buy an iPhone it is best to have an Apple computer or you will not be able to enjoy all the iPhone features. BTW, the Droid and Blackberry are Windows compatible. I hope my lesson learned the hard way will help others when making a decision about which phone to buy.

There are other options to make longer videos available for others to view. Telling people that you shouldn't buy an iPhone if you use a Windows PC is ridiculous....you do realize that despite Apple's popularity most of the computers owned are PC's and not MAC machines. Which would make it easy to assume that there are quite a few Windows PC users that are iPhone owners...and are more than happy with their device and it's abilities. If streaming is that important to you then for you, perhaps you either need a different device or you need to get a MAC. Otherwise, consider uplaoding the video to a platform that you can easily share all of your videos with anyone you wish. It's not rocket science and it doesn't make your videos any less shareable. FYI...perhaps this is possible on a droid device but prior to getting the iPhone I was a long time BB user. You COULD NOT stream or send long length videos to a computer or via text or any other format. You could sync it to the computer and upload it to a site that others could go view. You could upload the video from the BB to sites like FaceBook and YouTube, but the time it took was long depending on the video and more apt to fail....versus just syncing the video to your computer via the desktop manager and then uploading it to the site of your choice. I'm not an Apple worshipper...but your declaration based off of your inability to have access to a MAC program not because you have an iPhone, but because you chose to purchase a Windows PC is beyond ridiculous. And your assumption that you're the only person to have read the manual is laughable at best. Perhaps if you had done your research for the function you wanted to be able to do prior to purchasing your iPhone (the manual has been available for the iPhone online since the iPhone 4 was first made available to AT&T...several months before VZW got it, giving you plenty of time to research this info in that manner not to mention you had free access to forums such as the Apple Support forum that could have given you first hand info on whether the action you wanted to perform was possible for an iPhone owner that uses Windows PC. Plus, if you haven't had your phone for too long you have time to return it. If it has been too long you can easily sell it assuming that it is still is excellent condition and get very good money on it...money that can go towards getting the device you feel will better suit your needs. At any rate, good luck with whatever you choose. Hopefully you can find an alternative method to fit your needs...or you can get the device (or a MAC) to help you get what you are looking for.
