Doubt in performance

hi,
i am retrieving records from db. i am using java and jsp.
The table that i am using has nearly 1 lakh records. it's taking time to retrieve records from db. by the time, it retrieves, jrun gets time out.
and it's giving
JRun Connector Proxy request timed out
Please contact the system administrator for this web site.
how to solve this problem? can anyone help me?
Thanks,
Sri

Sounds like you need to clear down your database tables, can you not archive older records in a separate table?

Doubts about performance:
Hi:
In my work we have performance problems with the database (Oracle 9i v. 2), we have said that the TOAD consumes a lot of resources.
I know how to affect the performance of the database using a tool such as the toad.. ?
It is true that the use of inner join and left join instead of = and (+) is better?
Thanks

This is too broad a question.
Toad can fire random sql.
sql*plus can fire random sql.
Why would Toad be the problem?
You would need to gather statspack data to demonstrate this.
Sybrand,
Agreed on it and its a relevant point.But I guess he is not worried about the db performance.Anyways lets see what OP says.
Inner join and left join will always use CBO (Cost Based Optimizer) instead of RBO.
I am not sure that I have read that anywhere. They came into Oracle in 9i where optimizer mode was choose as the default one. Just by the syntax, oracle would push them to use CBO as the default one,I am not sure about this. Even if we are having + symbol and have the stats,Oracle wold go for CBO right?Can you please point me to some where in the docs where it is mentioned that using this keywords,Oracle would use only CBO?

Performance of a ABAP program

Hi Friends,
I have one doubt , in Performance of a ABAP program.
Which one gives good performance in Select Statement
Open Cusor.. Select ... Close cusor OR
Select ..Package Size <n>
If anybody having the Idea please let me know .
With Thanx.
Elango

Hi elangoraj,
1. There is no standard calculation / method
to determine the package size.
2. Its totally subjective and depends upon
- the total number of records in database table,
- the time taken to fetch one package
- how many fetches we want.
3. Usually It can be kept from 100 - 500.

Performance issue in a custom table

Hi All,
I have a ztable used in a program wherin I have a doubt of performance issue in selection.Its like :
    SELECT ship_no invoice_no
      INTO TABLE it_ship_no_hist
      FROM zco_cust_hist
      FOR ALL ENTRIES IN it_freight
      WHERE ship_no = it_freight-tknum.
there are 7 key fields in this table out of which one ( tknum ) is used in a where condition.The table is without any index.
   For performance purpose should I create an index with the very field 'tknum' in the index..can I do that or index should be created only along with non key fields.

Hi,
a table has - besides a few exceptions - always one index that is the primary key. The fields are the key fields in the same order as in the table.
The primary key is always there and therefore not displayed under the botton 'index'.
Is tknum a key field? What are the key fields in correct order? If it is in the key and maybe the first one, then it does not make sense that you create an index.

Diff Using and changing in Perform

Hi All,
       What is the difference betwen USING and CHANGING in Perform.
Thanks in advance
                                              Ranjith

hi,
Using helps to use the parameter value passed.
Changing helps to change the parameter value and then use the same in main program with changed value.
Sample:
data : val1 type i value 1,
       val2 type i value 0.
perform calc using val1 changing val2.
Write / : 'Changing :' , val2.
write / : 'Using :' , val1.
*&      Form calc
      text
     -->P_VAL1 text
     <--P_VAL2 text
form calc using    p_val1
           changing p_val2.
p_val2 = p_val1 + 100.
*p_val1 = p_val1 + 100.
*Since p_val1 is passed as using,the above is not *permitted
endform.                    " calc

Performance wise Code In smartform

Hello,
I have one doubt for performance issue in smartform.
While creating 'Z' smartform data fetching can be done by two ways,
Which one is better out of two mentioned -
1. Code in smartform itself.
2. Code in driver program and pass that data to smartform via form interface.
In SAP standard smartforms it is always done in Smartform itself.
Also please suggest which one is easy to debug?
Regards
Vishal
Edited by: Vishal Chavan on Jun 11, 2009 7:55 AM

Hi Vishal,
As far as i am concerned it is always better to separate the data selection from the data used in the smartform.
Having your code in a driver program has better advantage over the code in smartform.
1.It is easy to change and maintain the code.
2.You can use the driver program for different smartforms with minimal changes.
Performance and debugging doesn't differ much either you code it smartform or in the driver program.
For more information please go through the below link.

Performance issue session or bean?

hi,
i have a doubt regarding performance issue.
actually in my application, five jsp' s need to communicate each other. They share around 15 String Objects.
1. So right now i am using Session object to store
these 15 String objects.
2. Also my application can declare a class to
store all these 15 String objects as attributes and
then use <jsp:usebean> tag for communication
with session scope.
So now we have two methods for sharing information
in jsp application as stated above.
Can anyone help me which is the best method to follow as given above and why. Which does increase or decrease the web server load.
Thanks in advance.
Have a nice day.
Bye
Suresh

I'd go for wrapping up the data in a single object...not for any performance issues, just because it's far tidier.
As for performance, I doubt there is much difference although by wrapping up the data in one object you only have to call the session object once to get a handle on all 15 strings.

Best performance dual 30 inch cinema displays dual x1900 card(s) ?

I am trying to get the maximum performance out of my system. I have a Mac Pro with two 30 inch cinema displays. I have them both connected to one X1900 card.
I use LightRoom as my photo work flow manager. I spread the library across both monitors as I sort thru photos.
Performance is good but sorting thru several thousand RAW files I need every bit of speed I can get.
Would I get better performance if I used two x1900 cards, one for each monitor? how about the 7300 or the FX4500? would those improve speed or better just for gaming?
thanks in advance for any help.

Two Quad-core with 8-16GB RAM, and your media fles on RAID.
I'd configure with 4 x 750GB WD RE2s. Can't easily swap or upgrade cpu so that is a given until you know and Apple has something that would make sense to buy/swap to newer faster systems (maybe in a year or next summer).
There is no support for two 16x lane slots. Maybe in the future but not now.
I doubt your performance is limited or factor of the twin 30s on the Radeon. It might. Try running with just one monitor for a few hours.

Performance Scorecard in Hyperion

Can Any one tell me the steps how to make a Performance Score card,using Hyperion Performance score card on an URGENT BASIS.
Also I have the following doubts regarding performance score card.
1.From where do I get the data?
2.Do I need to connect it to a planning application?
3.What are the prerequisits for making the same.
It will be highly Appreciated if any techinical document regarding the implimentation of performance score card be shared.

Hi Aditi,
Performance scorecard is more of a framework that an sheer technical implementation of a product.
1. Scorecard results in definitions of KPI's and one has to measure these performance indicators. Hence, the data is according to the defined KPI's
2. As a part of Balance scorecard, a company strategizes. As per the strategy, goals are set and planning done. Based on the the set annual goals/long term goals, budgeting is done to define actions( this is done through Planning application technically).
3. Pre requisits would be to clearly define strategic objective, define KPI's i.e performance measures, decide the targets and finally deploy the scorecard project to measure these.
This is again more of a functional/ framework related query than Hyperion Planning product query.

How can you share a iPhoto library with another account user

I have recently seen the light and swapped from Windows to my lovely new iMac. However I am rather confused how I can configure my iPhoto library so my wife can view the same library in her account on the same machine (this was a simple thing within Windows, using shared folders). Am I missing something or do I have to duplicate the same library and place into my wife's account and then update each time we upload some photo's? Please help!

This may not be the "neatest" solution possible, but it's one that works. Just as iPhoto makes it easy to share photos between computers on the same network, you can also share photos between accounts on the same computer; but you'll have to be logged in with iPhoto running.
1) Configure iPhoto in your account for photo sharing (from iPhoto, select Preferences > Sharing> Share my photos).
2) Enable fast user switching from System Preferences > Accounts > Login Options. This is the key to the process, which will allow you to remain logged in while your wife is also logged in. It's also a very handy feature if you and your wife use the computer a lot from your own accounts.
3) Enable "Personal File Sharing" and "Remote Apple Events" from System Preferences > Sharing > Services. [I had already done this step, so I'm not sure if it's strictly necessary]
4) With iPhoto up and running in your account, use Fast User Switching to log into your wife's account (ie, you remain logged-in). [The Fast User Switching menu will be in the upper right of the main menu bar.]
5) From her iPhoto preferences, select Sharing > "Look for shared photos" if it's not already switched on.
Your photos will magically appear in the left hand column of your wife's iPhoto application using the name you designated in your copy of iPhoto.
Caveats: performance is not very good, you must be logged in and have iPhoto running, HP printers (if you have one) don't work well with fast user switching
Other solutions might be possible by "drilling a hole" into your account by altering the Unix permissions. I've used this technique to make my iTunes library available to other users on my machine. Such a solution would no doubt improve performance.
Finally, there are third-party products that allow you to manage multiple iPhoto libraries. I've never used these, but they might allow you to load the iPhoto library from another account assuming permissions are properly set.
Hope this is of some use; I'm sorry if it's a little more complicated than you might have expected.

Problems with iPhone 3.0 software on iPhone 3G

I love the iPhone 3.0 software update. I just wish that Apple can fix the following problems now:
1. The phone starts to slow down, real slow, a day after the update.
2. Battery uses up like crazy, takes a much longer time to charge, and the phone gets really warm when in use or when charging ever since the update.
3. Sometimes other parties could call in - they were directed to my voice inbox even though I was not using the phone. A friend of mine told me that he was experiencing the same problem, and that somehow it was resolved by turning on 3G.
4. Data connection, for Emails and apps, became much slower than before.
5. Happened once: Somebody sent me a text message, and my iPhone kept on receiving that same message every three minutes for an entire morning.
A 3.1 update that solves the above problem, any fellow user tips that solve the above problem, or a Palm Pre discount gift card would be greatly appreciated. Thanks!

I seriously doubt the performance would be any slower. There would be no point. I am sure in 3 or 4 iphones time the OS will be so advanced that the 3G iphone and it's 128mb RAM would not be able to run it. Just specualating, but by then the 3G will be long gone. I have the white 3G 16GB which has been discontinued now. That's why i am not getting the 3GS coz mine is quite rare now.

SYNC/ASYNC - Proxy to File

I have a sync proxy. It will sent a mesg. from R3 and I have to write it to a file and then from a diff file I have to read and sent a mesg. back to R3.
So Sync Proxy -> XI -> File1 : File2 -> XI -> Sync Proxy
Now I am sure a SYNC/ASYNC bridge will be used in BPM.
How many Mesg. Interface will come in the picture ?
1. sync outbound for the Proxy
2. async outbound for the incoming file
3. async inbound for out going file
4. Now for the abstract interfaces;
a. sync abs for proxy
b. 2 more abstract async interfaces (but what sud it correspond to ? the proxy req/resp or file req/resp)
My understanding is;
1. SyncReceive To Receive the payload synchronously from Proxy (open S/A Bridge)
2. Send To Send the request payload Asynchronously from BPM to the File system
3. Receive To receive the response Asynchronously from Legacy File system to BPM
4. SyncSend To Send the response Synchronously from BPM to Proxy (close S/A Bridge)
My design;
In SyncReceive To Receive the payload synchronously from Proxy (open S/A Bridge)
Sync Interface abst. Sync proxy
Message - Abs aysnc req. of proxy
In Send To Send the request payload Asynchronously from BPM to the File system
Message Abs aysnc req. of proxy
In Receive To receive the response Asynchronously from Legacy File system to BPM
Message Abs async resp. proxy
In SyncSend To Send the response Synchronously from BPM to Proxy (close S/A Bridge)
Message - Abs async resp. proxy
Can you confirm on this ? Kinda confused cos I havnt mentioned any mesg. interface pertaining to the file here

well, now that the design is confirmed (can somebody tell me y we dont mention any of the file interface in BPM), where do i actually handle my mapping ?
Cos i will have 2 mapping;
ProxyReq -> File1
File2 -> ProxyResp
and how do i go onto create my Interface mapping ?
Cos Proxy is a sync interface but file gets to be a Async.
And yeah Udo, i do seriously doubt the performance ... but well at this point i will leave that concern away and get onto build up the scenario.
Does is sound stupid ??? Well consider these questions to be be that of someone who encountered a SYNC/ASYNC for the very first time

Mysterious popping noises and dropouts

I have a very new iMac with 8 GB of memory so I doubt system performance is a part of my troubles, but Logic 9.1.1 keeps giving me trouble on a project I'm working on. In a few places on the song, the audio on a couple tracks drops out for a few milliseconds and then back in. This isn't due to compression or limiting or anything and I have attempted raising the buffer size, turning on/off low latency mode, and nothing seems to matter. There is now also a quiet pop that occurs in just two places in a long trumpet accompanying part.
Needless to say this is incredibly frustrating. Oh, also, this happens on headphones and on studio monitors.
Any ideas?

And since you are from cupertino, maybe knock on the door of your neighbour...

Report writers

Thanks for you reply.
We are currently testing Actuate.
Geoff, we have just had a look at your Forte integration sample on the Web.
It seems quite interesting.
At this point we still have two main doubts:
1) Performance
The starting point must be our Forte application, not the reporting tool :
this means we first have to call Actuate (or whatever) from Forte
environment (by using Actuate API), second we have to call Forte SO (through
OLE) from Actuate for making queries.
Have you any feeling of the performance of this round trip?
2) Multiplatform support
We agree that OLE is the best way for including Forte SO as a data source
for the reporting tool, but what
about Unix platforms?.
Thank you again

Actuate has a report writer which allows you to specify
data sources other than SQL and database querying.
In fact, you can use a Forte service object to fetch
the data for your Actuate reports. The "catch" is
that you need Forte R3 to make it work, with the
R3 feature of creating an OLE Automation Server from
your Forte service object. I have put a sample of
such integration on the Forte home page, in the
"Shareware" section.
Good luck!
Geoff ([email protected])
Chiaberto,
I do not think that you are wrong, but very correct. At Fox, we have a
complex query that is done by Forte that we do not want to duplicate in
our reporting tool and our intent is to pass it a result set. Creating the
same logic twice is definitely not the way to go.
You should be able to find a solution. At a minimum you should be able to
write a query result to a temporary table and they call the report writer to
format and print the query. Idealy this should be able to happen in
memory without using the database for passing the data. We are hoping
to use a C call interface to our report writer to handle this. Our vendor
assures us that it is possible. We'll see.
Another thing to consider is allowing your report writer to call a Forte
service to request data for reporting. Then you could re-use a forte
query from within the report writer.
Gregg ( [email protected])

We have just begun creating our first Forte application and are investigating
tools for creating reports from an Oracle database.
Has anyone had great success (or major disasters) with a particular reporting
tool?We've had really lousy experience with Chrystal Reports. It's unstable,
unpredictable and hard to manage. However, it can be used as an OLE
server, so it is possible to call Chrystal Reporst from a Forte
application, specify which report to print and open a Print Preview
window. Of course only on a Windows platform.

Idoc to Flat File doing Append

Hi All,
We have a scenario where we have to receive an Idoc from SAP and then map it into a flat file to a third party using FTP protocol in File adapter.
The main idea is to collect all the idocs generated each day and append it into the same target file during all the day so when a new day is coming XI should have to create a new file and start appending the data into it.
Is this possible to do with XI sp14?
Thanks in advance.

hi
yes u can do this. check for the blog on idoc collection:
<u><b>Collecting idoc's without BPM refer this blog,</b></u>/people/stefan.grube/blog/2006/09/18/collecting-idocs-without-using-bpm
Also, Just check the following two weblogs.

Here i doubt of performance issues. Maybe u can collect the idocs in one file as and when it reaches xi and u can have another interface scheduled at the end of day that will transfer the file content to another file (appended)
