Flash chart performance issue with multiple series
Hi,
We have a problem with the performace of a line graph which has multiple series.
I have set up an example application here:
http://apex.oracle.com/pls/apex/f?p=37504:1
The application contains two charts. The 'Mulltiple Series' chart has twelve series behind it and allows the user to include mutiple series data. The other chart has just one series.
The single series chart takes only a couple of seconds to render, however the mutiple series chart takes around 10 seconds even when no additional series have been selected. Using Firebug I have observed that the apex_util.flash procedure is taking around 8 seconds to generate the XML, and it includes null data values for the series that aren't selected.
My question is how can I make each series conditional, such that no data is included in the XML if the series returns no rows?
Thanks,
Andrew
Hi Andrew
Have you considered modifying your chart to use a series with the "Query source type" of "Function returning SQL Query"
Have a look at
Re: Flash chart - multiple series - no display when some series empty
My response on that thread may help. I'd be interested to know if this approach improves the performance.
Kind regards

Performance Issue with Multiple Joins :-)
Hi there! I have a dilemma over using multiple joins...and I am not sure whether there is any alternative to this. Please help me out if you can..
I have a table DATA having 100 columns and 2 million records and I have another metadata table Code_Mappings. The issue is with migration of this data from upstreams to downstreams.
Columns of DATA table is
a,b,c,d,e,f,g,h.......ca.cb.cc.cd.....dz.
Code_Mappings table is
Source_code |Target code | category
The problem arises when I join the metadata table for multiple joins..
Around 75 columns out of 100 are category questions i.e I need to replace all Source codes in the data of those category columns with target codes WRT categories..
Suppose A, C,D,I,J,K,L,W,X,Z,AA,BH are country category.
My query to fetch data from DATA for column A would be
Select decode(d.A, cm.source_code,cm.target_code,d.A) from DATA D,Code_Mappings CM where cm.category like 'country' and d.A=cm.source_code;
In the similar way, I may have to join the same table for category 'country' for n no of columns if those columns have category as 'country'.
Is there a alternative to use this table once and use the decode, mapping logic multiple times on columns..? Please let me know if there is anyways I can do it so that performance is enhanced in a significant manner.
Another Issue is:
Whenever the Column value is some junk, that record doesnt get fetched. In the above query, you can see that where clause has a condition of "d.A=cm.source_code" which not only filters out these required records but also avoids cartesian product.
The basic requirement is all records should get fetched. I do not want to filter out anything.
Please help me out.
Thanks
Mahesh1) I'm not a JD Edwards person, but I would wager that if you're to the point where you have consolidated all the schemas to a single instance that it would be possible and preferrable to consolidate everything further into a single schema. I have to believe that JD Edwards provides tools to restrict what bits a particular branch can see without requiring separate instances.
2) What data are you accessing exactly? Are you always accessing data for a particular branch? Or do you need information from every branch?
3) Is your application logging in as a single user? Or will there be 1 application user for every JD Edwards schema?
4) Are you deploying your PL/SQL into 10-20 different schemas? Or into just 1?
Whether or not you are explicitly using the schema name, Oracle will have to do a hard parse of every logically distinct SQL statement. Two SQL statements that access different tables that happen to share the same name are logically distinct, so your shared pool will end up with 10-20 copies of the "SELECT * FROM <<some table name>>" SQL statement if it is executed against every instance of <<some table name>>.
The question may be whether it is better to explicitly provide the schema name or to rely on synonyms. You generate the same number of hard parses either way, but explicit schema names may improve latch contention during parses if Oracle has to do a lot of synonym resolution. Not many people/ applications are really hurt by this latch contention, though, so it is very hard to say whether this is a legitimate concern.

Performance issue with multiple installations of 1 application in 1 databas
In our company we use JD Edwards. Every branch has its own JD Edwards installation in a separate schema but in the same database (Oracle9i Enterprise Edition Release 9.2.0.7.0) => In 1 database there are 10-20 copies of each table.
On top of JD Edwards we are developing a Java/JSP application which accesses the JD Edwards data by means of pl/sql stored functions returning ref_cursors. Our DBA states we have to prefix all our tables/views within our stored functions for performance reasons. According to him omitting the schema name would result in increase of hard parses, because the shared_pool can only store 1 occurrence of an sql statement. So only the statement of 1 branch is cached. The execution of the same statement in anothers schema would lead to a hard parse and not to a soft parse.
For us developers the use of schema names complicates the development process, because we have to use a substitution parameter (&schema_name) in our coding which prevents us from maintaining our code in tools like Toad.
Questions
* Does it make sense to use the schema name in this case?
* Is there another way (not using schema names) to get a good performance in this situation?
Thanks,

Candlestick chart problem with multiple series
Hello,
I added one mx:CandlestickSeries object and couple additional
mx:LineSeries objects to the chart. All series are represented but
still I have one problem. More series I add - less candles are
becoming of CandlestickSeries data. It seems that there should be
any scaling option for all series in the chart or something like
this, but I cannot find it. I'm still new in Flex Can anyone halp
me with this?
Thanx in advance
marukasI've added screenshots to get better view of the problem.
Here is chart with addtional series:
Chart
with multiple series
And here nothing is changed except that additional line
series were removed:
Chart
with only one CandlestickSeries
Is it possible to get the same candles as in 2nd view with
addiotnal series added? -
Line Chart with Multiple Series
Post Author: JayZee
CA Forum: Charts and Graphs
HI
I am trying to create a line chart with multiple series for trend analysis on CR XI but not having much luck, I thought it would be so simple to do!
My data is provided summarized on the server and is returned as 12 rows:
Month Year1 Year2 Year3 Year4 Year5January 100 80 75 90 120February 85 25 40 25 80etc for the rest of the months
My problem is that I can only get the chart to accept the values to display as a summary and not just as the data pulled back from the server. I have read an article on the support site for Crystal 6.0 but it doesn't seem to translate well into XI.
If necessary I could redesign the table to bring back un-summarized data but that is quite a big job.
Any help greatly appreciated.

In the chart expert, put Month in the 'On change of' box and put each year in the 'Show values' box. This puts the month on the x-axis and plots each year as a line.
Is that what you want?
I did this in CR 2008 using your data in an Excel sheet. -
Performance issues with Imac intel 2011 27 inch..
I have an 2011 imac 3,4 GHz Intel Core i7 with 16 GB 1333 MHz DDR3 RAM.
Since a few months i noticed performance issues with FCPX, where before it would run through video it shows sometimes the color ball. Now the computer is slow in starting up and shutting down also. Ran disk utility but to no avail. I am now considering reinstalling mavericks.
But I ran etrecheck.
here are the results, please who can help me? I use this computer to edit and about everything else.

Hi all,
I'm facing some performance issues with Spry. I'm using it
for handling a menubar acting as a rollover menu : its color
changes under mouse cursor, and a submenu does appear at the same
time.
I have no problem when working with Firefox, but in IE6, it
renders too slowly
Is there something I've missed in the configuration or code
(or is there some tips for this kind of problem) ?
For information, I used UL and LI html tags, and I've
configured Spry to render these as a menubar (with multiple levels)
Thanks for your responseSorry, there are no public access to this application

Perf issues with Time series function in OBIEE
Attached is the SQL:

AND T610485.HIERARCHY_SOURCE = 'AltViews'
AND SAWITH6.c3 = '2009 / 11'
AND SAWITH6.c2 >= SAWITH3.c2
The SAWITH3 and SAWITH6 dimensions using time series fuctions are causing a full table scan on W_GL_BALANCE_F and W_GL_ACCOUNT_D . Though we are interested in just getting 2009/11 data; the queries generated by time series function TODATE is taking us against entire W_DAY_D data and is causing several performance issues.
W_GL_BALANCE_F table has index on GL_ACCOUNT_WID and BALANCE_DT_WID.
How can we force to use index on these columns for better performance.
Please advise us on the right approach to improve performance.

Srini PendemHi Srini,
I've had quite a bit of performance issues with ToDate and Ago. I tended to create materialized views on my fact tables that would materialize those values as columns and that way I would avoid having to use the ToDate or Ago functions. Is there any chance you can implement a similar solution and bypass the time series functions entirely?
Just to check, those tables belong to BI Apps, right? If so, you can log an SR about the performance issue since it's an issue with the model that Oracle sold you.
Good luck!

Performance issue with BW Reports for concurrent users
All:
I notice that one BW report that runs in few seconds will take upto 3.5 minutes when multiple users run it at the same time.
We are in BW 3.5 and we run reports for portal.
Does anyone have any suggestion about how to handle performance issue with concurrent users?
Thanks,
PranabHi,
use the OLAP-cache and/or aggregates and consider using load balancing to distribute the users to several servers.
Kind regards

Performance Issue with SXMB_MONI
Hi All,
I have a typical performance issue with SXMB_MONI, when I trigger this T.code it is taking around 20-24 hrs to execute.
Here I have found some tables which actually stores these processed xml messages,
SXMSPFADDRESS
SXMSPFRAWH
RSXMB_REMOTE_SERVICE
SXMSPFAGG
SXMSCONFVL
SXMSPMAST
SXMSPEMAS, SXMSPERROR, SXMSPMAST & SXMSPVERS.
SXMSPMAST, SXMSPMAST2, SXMSCLUR, SXMSCLUR2,
SXMSCLUP, SMXSLUP2, SXMSPFRAWH,
Here I want to increase the performance of sxmb_moni, firstly I want to know from which tables does the sxmb_moni fetches data and more over is it a single table or multiple table.
And please suggest any technique which can decrease the latency time in executing sxmb_moni.
Regards,
Vijay NHi,
Periodically you need to archive the XI messages, that allows you to maintain sufficient performance level.
Create archive jobs in SXMB_ADM to archive data which is 15 days old from XI related growing tables like SXMSCLUR, SXMSPEMAS, SXMSPHIST, SXMSPMAST, SXMSPVERS, SXMSPFRAW ,SWWWIHEAD. This archive job created archive files at the OS Level
For XI tables refer
/people/gourav.khare2/blog/2007/12/12/interesting-abap-tables-in-xi-150-part-i
SXMSPMAST, SXMSCLUP, SXMSPCLUR
the last two are cluster tables
and you won't get XML messages directly from them
have a look inside them
The classes that reads this information in SXMB_MONI are abap classes,
(can be seen at SE24) it is quite difficult to use them,
you might debug SXMB_MONI or use SE30 and see all the classes
that have been used.
You can use value mapping if you are not looking at picking up values from application system.It is just like SM30 transcation.You can get the info under SAP XI->Design and Configuration->Configuration->Value Mapping.
Also see the
these tables,
/SAPDMC/LSOMAP Field Mapping
/SAPTRX/SCAOTMAP
/SAPTRX/SCCNDMAP /SAPTRX/SCEVTMAP
/SAPTRX/SCFUNMAP /SAPTRX/SCSOMAP
/people/udo.martens/blog/2006/02/16/own-logging-of-xi-messages
message-mappings: stored in which database-table?

Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?
Thanks Kelly,
The answers would be the following:
1200 cells per custom section (NEW COUNT), and up to 30 custom sections per spec.
Assuming all will be populated, and this would apply to all final material specs in the system which could be ~25% of all material specs.
The cells will be numeric, free text, drop downs, and some calculated numeric.
Are we reaching the limits for UI performance?

Performance issues with pipelined table functions
I am testing pipelined table functions to be able to re-use the <font face="courier">base_query</font> function. Contrary to my understanding, the <font face="courier">with_pipeline</font> procedure runs 6 time slower than the legacy <font face="courier">no_pipeline</font> procedure. Am I missing something? The <font face="courier">processor</font> function is from [url http://www.oracle-developer.net/display.php?id=429]improving performance with pipelined table functions .
Edit: The underlying query returns 500,000 rows in about 3 minutes. So there are are no performance issues with the query itself.
Many thanks in advance.

Like:
- a database version
- how did you test
- what data do you have, how is it distributed, indexed
and so on.
If you want to find out what's going on then use a TRACE with wait events.

Performance issues with Homesharing?
I have a Time Capsule as the base station for my wireless network, then 2 Airport Express setup to extend the network around the house, an iMac i7 as the main iTunes Library and couple of iPads, and a couple of Apple TVs. Everything has the latest software, but I have several performance issues with Home sharing. I've done several tests making sure nothing is taking additional bandwidth, so here are the list of issues:
1) With nothing else running, trying playing a movie via home sharing in an iPad 2 which is located on my iMac, it stops and I have to keep pressing the play button over and over again. I typically see that the iPad tries to download part of the movie first and then starts playing so that it deals with the bandwidth, but in many cases it doesn't.
2) When trying to play any iTunes content (movies, music, photos, etc) from my Apple TV I can see my computer library, but when I go in on any of the menus, it says there's no content. I have to reboot the Apple TV and then problem fixed. I's just annoying that I have to reboot.
3) When watching a Netflix movie on my iPad and with Airplay I send the sound to some speakers via Airplay through an Airport Express. At time I lose the connection to the speakers.
I've complained about Wifi's instability, but here I tried to keep everything with Apples products to avoid any compatibility issues and stay within N wireless technology, which I understood it was much more stable.
Has anyone some suggestions?Hi,
you should analyze the db after you have loaded the tables.
Do you use sequences to generate PKs? Do you have a lot of indexex and/or triggers on the tables?
If yes:
make sure your sequence caches (alter sequence s cache 10000)
Drop all unneeded indexes while loading and disable trigger if possible.
How big is your Redo Log Buffer? When loading a large amount of data it may be an option to enlarge this buffer.
Do you have more then one DBWR Process? Writing parallel can speed up things when a checkpoint is needed.
Is it possible using a direct load? Or do you already direct load?

Performance issues with the Vouchers index build in SES
Hi All,
We are currently performing an upgrade for: PS FSCM 9.1 to PS FSCM 9.2.
As a part of the upgrade, Client wants Oracle SES to be deployed for some modules including, Purchasing, Payables (Vouchers)
We are facing severe performance issues with the Vouchers index build. (Volume of data = approx. 8.5 million rows of data)
The index creation process runs for over 5 days.
Can you please share any information or issues that you may have faced on your project and how they were addressed?Check the following logs for errors:
1. The message log from the process scheduler
2. search_server1-diagnostic.log in /search_server1/logs directory
If the build is getting stuck while crawling then we typically have to increase the Java Heap size for the Weblogic instance for SES>
