Poor Bex performance..Please suggest

Hi,
We have some queries which are giving data in 10 seconds on Bex Analyzer but the same queries are running for more than 100 seconds to return the data on Bex Web.
We did caching for the queries and configured the RFC connections but no performance improvement. Any kind of suggestions will be appreciated.
We are running on NW04s SP10 on both BI and Portal.
Thanks,
Damodhar.

hi Damodhar,
note sure the old notes applicable for you
Note 568844: Very long HTML load times (compared with Analyzer) (up to BW 3.0B Support Package 7)
Symptom
Compared with the BEx Analyzer, it takes a very long time to create a page in the Web application using navigation (for example, filter and drill down to...).
Reason and Prerequisites
If you start Web applications using the current Web browsers (for example, Internet Explorer 5 or higher), these are optimized for a flicker-free screen change.
This occurs with JavaScript operations which take a very long time for large lists in the Web browser.
Solution
As of a certain page size, it is more efficient to create the Web page completely from scratch again. As of Support Package 7, this is checked automatically by BW and a new page is initiated, if necessary. For customers with an older Support Package version, we recommend you deactivate the snippet operation for this page.
You can do this, for example, by enhancing the URL with:
&SNIPPET_OPERATIONS=
For example, http://.../sap/bw/BEx?...&SNIPPET_OPERATIONS=.

I need to check comparative three conditions and for each output I need to perform some action. can anybody please suggest

I need to check three comparative conditions and for each status I need to perform some action. can anybody please suggest
Requirment:
Need to check if a numeric value is within a number range by using comparative function. Depending on status i need to ggive a constant input to numeric function.

Easiest is suing an array of range boundaries, e.g. as follows:
(Found here)
Now it is fully scalable and independent of the number of ranges. The solution in the earlier post would get complicated quickly whenever the number of ranges or boundary locations changes.

Socket based application - Performance Issues - Suggestions Needed

Hi All,
We have an application which basically has been developed using core java. Here is a high level information about the application:
a) It opens a serversocket which allows clients to connect to it.
b) For every new client connection, a separate thread is created and this thread deals with requests from clients, processing the data and replying back to clients.
c) Each socket is polled continuously and sockettimeout is 2 seconds. If there is a timeout, we handle the situation and socket is again read. So basically sockets is read every 2 seconds. If number of timeouts reaches a configurable value, we close the connection and thread is dropped as well.
d) In production, three instances of this application are running with the help of a cisco load balancer. It is there for last 5 years.
However there has always been some minor performance isssues and we have sorted them out using different types of garbage collectors, by introducing hardware load balancers, upgrading the code for new Java versions. It is currently running on 1.4.2.
However there has always been some performance issues and today while googling over internet I came across following on the bea website which says that core java sockets are not as efficients as native API. BEA has implemented its own APIs for weblogic. My queries are:
a) Are there any better Java Socket/network API (for solairs, I know Java is plateform independenet but there could be lib which also using native libs) which are much more efficient than Core Java.
b) We are getting the InputStream/OutputStream and creating objects of DataInputStream/DataOutputStream to read the data 'Byte-By-Byte'. Each byte can have different information thats why it is required. Are there any better way of getting info than what we are currently doing.
c) As I mentioned, we are continously polling the socket for read operation with a timeout value of 2 seconds. What is the better among the following from performance point of view: (1) Frequent read operation with a lesser timeout value or (2) Less Frequent read operations with larger timeout value. (3) Any better idea??
Please suggest few things or pointers which I could do to improve the performance of the applcations. Many thanks.
Thanks,Akhil
From BEA website:-
"Although the pure-Java implementation of socket reader threads is a reliable and portable method of peer-to-peer communication, it does not provide the best performance for heavy-duty socket usage in a WebLogic Server cluster. With pure-Java socket readers, threads must actively poll all opened sockets to determine if they contain data to read. In other words, socket reader threads are always "busy" polling sockets, even if the sockets have no data to read. This unnecessary overhead can reduce performance."

My recommendations:
- Always use a BufferedInputStream and BufferedOutputStream around the socket streams
- Increase the socket send and receive buffers to at least 32k if you are on a Windows platform where the default is a ridiculous 8k, which hasn't been enough for about 15 years.
- Your 2-second timeout is far too short. Increase it to at least 10 seconds.
- Your strategy of counting up to N short timeouts of S seconds each is completely pointless. Change it to one single timeout of N*S seconds. There is nothing to be gained by the complication you have introduced to this.

IIR 2.8.0.7 performance tuning suggestions / documents for Oracle 11?

Would we have any hints or white papers that would support a customer in IIR matching server tuning for initial load performance,
beyond the Siebel specific
Performance Tuning Guidelines for Siebel CRM Application on Oracle Database (Doc ID 781927.1)
which does NOT generate any statistics on the Informatica Schema?
Customer is starting production data load into Siebel UCM of over 5 million customer records . Their current bottle neck seems to be IIR queries and high IIR host resources usage.
This would be for Siebel 8.1.1.4 [21225] on Oracle 11.1.0.6; I currently do not know if ACR 475 with its EBC access is used or not; I'd be looking for any performance tuning suggestions on the Informatica & database side - I have not found anything helpful in the informatica knowledgebase and in the 2.8.0.7 docs the only performance tuning suggestions seem to be on IDT loads.
Obviously performance can be influenced by the matching fields used, but this customer will be looking for performance tuning suggestions keeping the matching fields and thresholds they got approved from the business side.
Any documents we could share?

Hi Varad,
Well, Oracle Metalink actually got it fixed for me! Got to give them credit.
I ran the 1st bit of SQL they sent me and it fixed it so I think it was only cosmetic. I've enclosed all of their response in case others may find themselves in similar situation.
Thanks again for YOUR help too.

1. Do you see any invalid objects in the database?
2. Please update the SR with the output of running the commands below
1.Connect as SYS.
set serveroutput on (This will let you see if any check fails)
exec validate_apex; (If your version is 2.0 or above)
If all are fine, the registry should be changed to VALID for APEX and you should see the following

Note : The procedure validate_apex should always complete successfully.
With serveroutput on, it should show why Application Express is listed as invalid.It should show output like:

Poor Bluetooth performance with all aluminum Mac Pro

The all aluminum case for pre-mavericks Mac Pro is the primary reason for poor antenna performance of Bluetooth. Aluminum, being a good conductor, acts as a reflector of EMF forming what is known as a Faraday Cage, essentially trapping emissions within the box. Normally, holes drilled in the case would allow enough EMF to pass through the case but the hole size for transmission is directly proportional to the lowest frequency that will pass through easily. An example is the typical microwave oven where the window is actually a conducting sheet with small enough hole such that higher freq light waves pass easily through the sheet but lower frequency microwaves do not. Perhaps if the drive bay covers were made of plastic, transmission of the Bluetooth and wifi would be sufficient. One might carefully nibble a slot or two in the side door but this would surely invalidate any warranty and care would have to be taken not to get aluminum particles inside the computer. This would probably nullify any FCC approval of the machine due to clocking noise interference with other devices. The best approach would probably be a tuned waveguide that passes frequencies only around 2.4 GHz ~ 5 GHz through the case (very similar to the way tuned ports on audio speakers pass a band of frequencies needed to extend bass response). I'm sure Apple will have corrected this design flaw in the new Mac Pro introduced this year. If you have lots of time on your hands you can get a college level text on electromagnetics (Maxwell's Equations, etc.) and derive all the details but with a bit of experimenting and reading about tin can antenna mods to wireless routers you should be able to improve Bluetooth performance significantly.

Thanks for the suggestion. I will have to move my wireless home base station. It is on the same desk as my mini so much less than 5 feet away.

Poor 3G performance from Hutchinson 3 Service Provide at HK

any Hong Kong 3G iphone users experiencing poor 3G performance on Hutchinson 3 network? test my 3G iphone against original EDGE iphone at same spot on office floor, browsing to www.yahoo.com and the performance was marginally quicker than EDGE. after calling our service provide, being told that we were capped on network bandwidth of 7.2mbps but the real speed testing was around 0.3mbps.... this is unacceptable performance.

I think you have the hints in the wrong place - as far as I was aware, the hint had to come straight after the SELECT/UPDATE/INSERT/DELETE key word - but I could be wrong as I've never really tried it elsewhere. Also, unless the optimiser mode for your database is set to FIRST_ROWS or RULE (god help you!:), ALL_ROWS is the default behaviour.
Basically what you are trying to say is bring me back all ra_customer_trx_all rows that have purely numeric trx_numbers right?
Why, if you need to be able to represent trx_number as a number, do you have non-numeric data in there???? That's a bit dodgy isn't it?
Anyway, what about:
CREATE TABLE dt_test_num (id varchar2(10))
insert
into
     dt_test_num
select
     chr(47 + rownum)
from
     all_tables
where
     rownum <= 20
select
     to_number(id),
     id
from
     dt_test_num
where
     translate(id,'0123456789',' ') IS NULL
update
     dt_test_num
set
     id=id||chr(67-rownum)
select
FROM
     dt_test_num
select
     to_number(id),
     id
from
     dt_test_num
where
     translate(id,'0123456789',' ') IS NULL
/Also, you are selecting rownum and aliasing it. Why? rownum will be assigned before the sort.

Modular or New Custom Component Approach : Please suggest

Hi ,
I am developing a Flex Application which will used within the organization of Employees
Please suggest me , as what to approach to follow to develop this :
After an user (Employee) of an Organization logins , he can be allowed to do various operations
depending upon various modules .
Should i develop each of these things using Flex Modules approach or normal New Component ??
please suggest an approach

@kiran7881,
If your each module is individually large in size and involves lot of code and stuff and if number of such modules are more then you can go with modules concept.
Otherwise if your stuff involves simple and small operations to perform then you can go with creating normal Components approach.
Thanks,

There are several things that could make the computer run slower than expected
or slower than previously experienced from time to time; if a new system was
installed into a computer with slowness and other issues, that may compound the
problem since an upgrade to an OS X is not necessarily a remedy for old trouble.
If the issue may be a performance concern, there are cause and effect reasons
behind computer functionality. And if the computer was super quick, then after
an upgrade to a newer OS X, super slow, there could be several things going on.
The software previously working in the computer may not be correct for a newest
operating system; or the computer hard disk drive may be getting too full of content
that has no relation to the function of the device. Not enough unused storage space
or capacity can contribute to an overall slowness. And this also would relate to the
computer's use of resources. More installed chip RAM can help a computer run
better, and if you have extensive saved content in the computer you made, get an
externally enclosed hard drive and see about how to go & move that accumulation
off the computer's limited space so it could run better.
•Mac Performance Guide - thesafemac:
http://www.thesafemac.com/mpg/
•Tech Guides - in addition to the above - from thesafemac:

There may also be adware or other kinds of malware inadvertently installed in your
computer; so that is something else to consider, find & remove. Note info in guides.
You could use the Activity Monitor in the Utilities folder (see Go in Finder menu) to
see if there are applications or processes running extensively that could point to
some waste of system resources. If there is something actually using anything at all
out of the ordinary. These kinds of things are hard to judge - if you aren't familiar.
So, anyway, hopefully you can get some ideas from the above site pages to help.

Hi,
Type is one part of Org creation....
Optionally, select an organization type in the Type field.
Organization types do not classify your organization, you use them for reporting purposes only. The type may identify the function an organization performs, such as Administration or Service, or the level of each organization in your enterprise, such as Division, Department or Cost Center. You create the organization types you require by entering values for the Lookup Type ORG_TYPE.

Out place upgrade from 11.1.1.4 to 11.1.2.2. Please suggest.

We are planning to do an out place upgrade. We are on 11.1.1.4 right now. And the plan we have come up with is, is to install 11.1.1.4 on new server, perform lcm migartion, and then upgrade 11.1.1.4 to 11.1.2.2. Is there anything wrong or is there a better approach to the one we are taking? Please suggest.
Thanks,
Tej.

You can upgrade directly from 11.1.1.4 to 11.1.2.2 and they don't have to be installed on the same server.
Everything is in the documentation - http://docs.oracle.com/cd/E17236_01/epm.1112/epm_install_1112200/launch.html
If still is not clear then it may be worth getting someone in to discuss your upgrade options.
Cheers

Please suggest Partition for following example urgent

Hi all
my table have one column Year
I need to create 2 partition year_1,year_2 for year column but synario is
If 2004 ,2005 2004 must go into year_2 and 2005 must go into year_1
also for 2006 must go into year_1 and 2005 into year_2
Please suggest type of partition if possible with example
Regards

> I need to create 2 partition year_1,year_2 for year column
<snipped>
An exceedingly bad idea to partition a date range like this - stuff some data into one partition and some other data into another partition, without any logical condition that governs what data must go into which partition.
So do not create just two partitions. Decide on the partitioning strategy you want based on criteria such as:
a) volume of data
b) access to data (i.e. predicates used)
c) data management requirements (e.g. removing or aging old data from the table)
Satyaki's example shows you the basics of how this should be done. A partition by year. Or, monthly or even daily partitions. And possibly even sub-partitions.
You will be achieving nothing in terms of performance or data management by trying to stuff date ranged data into two partitions as you are indicating.
As for future yearly partitions? Create yearly partitions for the next 10 years. Or 20 years. Or 100 years. They will be empty. Small space footprint. Ready to be used.
In this case there are relatively few (yearly) partitions - far less than having to deal with 1000's of daily partitions where it is often a better idea to automate adding of new partitions using a DBMS_JOB.

BI Statistics Highly Aggregated cube 0TCT_CA1 poor load performance

BI Statistics Highly Aggregated cube 0TCT_CA1 load ffrom DataSource 0TCT_DSA1 has very poor load performance.
In our DEV BW, it ran 8 min for 12,000 records. We have even worse performance in test box.
Initial loads then run very long since DataSource 0TCT_DSA1 does not allow us to load by calendar month.
If you have seen this issue, please let me know.
Jay Roble
General Mills

Compressing the cube would not help, since the cube is empty & we are trying to load 90 days of history.
The source table has an index on the timestamp field that the extractor uses in it's delta loads.
The loads run very slow, even with index dropped & no PSA.
We know that in production there will be appx rows 400,000 loaded 14,400 added with daily delta loads due to aggregation.
So we are seeing slow delta loads in our QA testing.
Not sure why the extractor can't just deliver the 14K aggregated rows vs. 400K.
Note: DS 0TCT_DSA1 has no selction criteria when doing initial full loads.

Poor System performance after EHP4 upgrade

Hello Experts,
We have just finished our Upgrade to EHP4 for ECC6 system. After the upgrade we are noticing awfully slow system response time.
My SGEN is currently executing and it's showing another 45 hours before it is finished. Are there specific post Upgrade activities that I am missing? Once I try to perform some action it takes ages to compile the program. I undesratand that since SGEN is not run yet so it will need some time to compile and generate load for the application but still the response is takinng agaes before I see the actual Application/Program active in GUI.
Please suggest what I can do to boost up my system performance.
Thanks,

Poor query performance only with migrated 7.0 queries

Dear Team,
We are facing a serious query performance issue after migration of queries from 3.5 to 7.0.
I executed a query in 3.5 with some variable values which takes fraction of seconds to display the output. But the same migrated query with same variable entries is taking very long time and giving time out error.
We are not using any aggregates in the InfoProvider level.
Both the queries are based on same cube but 3.5 query is taking less time and 7.0 is taking very long time if more selection is done.
I checked for notes where I didn't find specific note for this particular scenario. I found notes only for general query performance improvement.
I want to know the reason why only in 7.0 the same 3.5 query is taking a long time and giving time out error. And please suggest some notes or suggestions related to this scenario.
Regards,
Chan

Hi,
Queries in BI 7.0 are almost the same as queries in 3.x format.
inorder to check if the problem is in the query runtime (database time) or JAVA runtime (probably rendering) you should try running it from RSRT once in JAVA web and once in ABAP web.
if the problem is only with JAVA web, than u should take the URL and add &profiling=X at the end.
after the query execution u can use statistics which will be shown at the top of the page.
With my experience, the problem is in the rendering phase of the query. Things that could be done is to limit the number of rows shown at each page, that could be done by changing the 0ANALYSIS web template - it's one of the web template parameters.
Tomer.
