PERFORMANCE PROBLEM - SYS OBJECTS
Hi all,
I'm having something strange here! The performance of queries that run against SYS objects like view DBA_OBJECTS , DBA_SEGMENTS, DBA_EXTENTS are VERY SLOWLY!! It's hang everytime and i need to kill the session and the PID process.
One example is the following:
SELECT owner, object_name, object_type FROM sys.all_objects
WHERE object_type IN ('PACKAGE', 'PROCEDURE', 'SEQUENCE', 'TABLE', 'TYPE',
'VIEW', 'FUNCTION') ORDER BY owner, object_name;
The objects of schema SYS was analyzed recently.
I have run the query with trace and nothing was found on that trace. The trace says the the query runs in few seconds but it didn't.
Any help?
Tks,
Paulo Portugal
Please take a look at the DBMS_XPLAN for the query to determine if there is a problem, and see if you are able to use DBA_OBJECTS rather than ALL_OBJECTS.
For example, on one of my databases, querying ALL_OBJECTS:

Performance problem using OBJECT tag
I have a performance problem using the java plugin and was wondering if anyone else was has seen the same thing. I have a rather complex applet that interacts with java script in a web page using the LiveConnect API. The applet both calls javascript in the page and is called by java script.
Im using IE6 with the java plugin that ships with the 1.4.2_06 JVM. I have noticed that if I deploy the applet using the OBJECT tags, the application seems the trash everytime I call a java method on the applet from javascript. When I deplot the same applet using the APPLET tag the perfomance is much better. I would like to use the OBJECT tag because it applet bahaves better and I have more control over the caching.
This problem seems to be on the boundaries of IE6, JScript, the JVM and my Applet (and I suppose any could be the real culprit). My application is IE5+ specific so I can not test the applet in isolation from the surround HTML/JavaScript (for example in another browser).
Does anyone have any idea?
thanks in advance.

Performance problem with recordset object
Hi,
I have a performance problem with record set object. Is it true using RecordSet object as argument to the method will cause any perfomance degradation?
here is my code.
finStmtList = selectFinancialStatements(rs, shortFormat, latestOnly, true);
I changed the code by populating the recordset in the method that called the above statement. previously the population of valueobject is within the select FinancialStatements.
Now the method looks like
finStmtList = selectFinancialStatements(ValueObject, shortFormat, latestOnly, true);
Is this fix will result in any performance gain?Can any one suggest me that the above RecordSet Object contains large number of records that counts up to 1000 rows and having 30 columns? I tested the application. But the performance varies from time to time.
Is there any other way to fine tune it? -
SQL report performance problem
I have a SQL classic report in Apex 4.0.2 and database 11.2.0.2.0 with a performance problem.
The report is based on a PL/SQL function returning a query. The query is based on a view and pl/sql functions. The Apex parsing schema has select grant on the view only, not the underlying objects.
The generated query runs in 1-2 sec in sqlplus (logged in as the Apex parsing schema user), but takes many minutes in Apex. I have found, by monitoring the database sessions via TOAD, that the explain plan in the Apex and sqlplus sessions are very different.
The summary:
In sqlplus SELECT STATEMENT ALL_ROWS Cost: 3,695
In Apex SELECT STATEMENT ALL_ROWS Cost: 3,108,551
What could be the cause of this?
I found a blog and Metalink note about different explain plans for different users. They suggested to set optimizer_secure_view_merging='FALSE', but that didn't help.Hmmm, it runs fast again in SQL Workshop. I didn't expect that, because both the application and SQL Workshop use SYS.DBMS_SYS_SQL to parse the query.
Only the explain plan doesn't show anything.
To add: I changed the report source to the query the pl/sql function would generate, so the selects are the same in SQL Workshop and in the application. Still in the application it's horribly slow.
So, Apex does do something different in the application compared to SQL Workshop.

Performance problems with XMLTABLE and XMLQUERY involving relational data
Hello-
Is anyone out there using XMLTABLE or XMLQUERY with more than a toy set of data? I am running into serious performance problems tyring to do basic things such as:
* Combine records in 10 relational tables into a single table of XMLTYPE records using XMLTABLE. This hangs indefinitely for any more than 800 records. Oracle has confirmed that this is a problem and is working on a fix.
* Combine a single XMLTYPE record with several relational code tables into a single XMLTYPE record using XMLQUERY and ora:view() to insert code descriptions after each code. Performance is 10 seconds for 10 records (terrible) passing a batch of records , or 160 seconds for one record (unacceptable!). How can it take 10 times longer to process 1/10th the number of records? Ironically, the query plan says it will do a full table scan of records for the batch, but an index access for the one record passed to the XMLQUERY.
I am rapidly losing faith in XML DB, and desparately need some hints on how to work around these performance problems, or at least some assurance that others have been able to get this thing to perform.<Note>Long post, sorry.</Note>
First, thanks for the responses above. I'm impressed with the quality of thought put into them. (Do the forum rules allow me to offer rewards? :) One suggestion in particular made a big performance improvement, and I’m encouraged to hear of good performance in pure XML situations. Unfortunately, I think there is a real performance challenge in two use cases that are pertinent to the XML+relational subject of this post and probably increasingly common as XML DB usage increases:
• Converting legacy tabular data into XML records; and
• Performing code table lookups for coded values in XML records.
There are three things I want to accomplish with this post:
• Clarify what we are trying to accomplish, which might expose completely different approaches than I have tried
• Let you know what I tried so far and the rationale for my approach to help expose flaws in my thinking and share what I have learned
• Highlight remaining performance issues in hopes that we can solve them
What we are trying to accomplish:
• Receive a monthly feed of 10,000 XML records (batched together in text files), each containing information about an employee, including elements that repeat for every year of service. We may need to process an annual feed of 1,000,000 XML records in the future.
• Receive a one-time feed of 500,000 employee records stored in about 10 relational tables, with a maximum join depth of 2 or 3. This is inherently a relational-to-XML process. One record/second is minimally acceptable, but 10 records/sec would be better.
• Consolidate a few records (from different providers) for each employee into a single record. Given the data volume, we need to achieve a minimum rate of 10 records per second. This may be an XML-only process, or XML+relational if code lookups are done during consolidation.
• Allow the records to be viewed and edited, with codes resolved into user-friendly descriptions. Since a user is sitting there, code lookups done when a record is viewed (vs. during consolidation) should not take more than 3 seconds total. We have about 20 code tables averaging a few hundred rows each, though one has 450,000 rows.
As requested earlier, I have included code at the end of this post for example tables and queries that accurately (but simply) replicate our real system.
Why we did and why:
• Stored the source XML records as CLOBS: We did this to preserve the records exactly as they were certified and sent from providers. In addition, we always access the entire XML record as a whole (e.g., when viewing a record or consolidating employee records), so this storage model seemed like a good fit. We can copy them into another format if necessary.
• Stored the consolidated XML employee records as “binary XML”. We did this because we almost always access a single, entire record as a whole (for view/edit), but might want to create some summary statistics at some point. Binary XML seemed the best fit.
• Used ora:view() for both tabular source records and lookup tables. We are not aware of any alternatives at this time. If it made sense, most code tables could be pre-converted into XML documents, but this seemed risky from a performance standpoint because the lookups use both code and date range constraints (the meaning of codes changes over time).
• Stored records as XMLTYPE columns in a table with other key columns on the table, plus an XMLTYPE metadata column. We thought this would facilitate pulling a single record (or a few records for a given employee) quickly. We knew this might be unnecessary given XML indexes and virtual columns, but were not experienced with those and wanted the comfort of traditional keys. We did not used XMLTYPE tables or the XML Repository for documents.
• Used XMLTABLE to consolidate XML records by looping over each distinct employee ID in the source batch. We also tried XMLQUERY and it seems to perform about the same. We can achieve 10 to 20 records/second if we do not do any code lookups during consolidation, just meeting our performance requirement, but still much slower than expected.
• Used PL/SQL with XMLFOREST to convert tabular source records to XML by looping over distinct employee IDs. We tried this outside PL/SQL both with XMLFOREST and XMLTABLE+ora:view(), but it hangs in both cases for more than 800 records (a known/open issue). We were able to get it to work by using an explicit cursor to loop over distinct employee IDs (rather than processing all records at once within the query). The performance is one record/second, which is minimally acceptable and interferes with other database activity.
• Used XMLQUERY plus ora:view() plus XPATH constraints to perform code lookups. When passing a single employee record, the response time ranges from 1 sec to 160 sec depending on the length of the record (i.e., number of years of service). We achieved a 5-fold speedup using an XMLINDEX (thank you Marco!!). The result may be minimally acceptable, but I’m baffled why the index would be needed when processing a single XML record. Other things we tried: joining code tables in the FOR...WHERE clauses, joining code tables using LET with XPATH constraints and LET with WHERE clause constraints, and looking up codes individually via JDBC from the application code at presentation time. All those approaches were slower. Note: the difference I mentioned above in equality/inequality constraint performance was due to data record variations not query plan variations.
What issues remain?
We have a minimally acceptable solution from a performance standpoint with one very awkward PL/SQL workaround. The performance of a mixed XML+relational data query is still marginal IMHO, until we properly utilize available optimizations, fix known problems, and perhaps get some new query optimizations. On the last point, I think the query plan for tabular lookups of codes in XML records is falling short right now. I’m reminded of data warehousing in the days before hash joins and star join optimization. I would be happy to be wrong, and just as happy for viable workarounds if I am right!
Here are the details on our code lookup challenge. Additional suggestions would be greatly appreciated. I’ll try to post more detail on the legacy table conversion challenge later.

The plan shows the nested loop access that slows things down.
By contrast, a functionally-similar SQL query on relational data will use a hash join and perform 10x to 100x faster, even for a single record. There seems to be no way for the optimizer to see the regularity in the XML structure and perform a corresponding optimization in joining the code tables. Not sure if registering a schema would help. Using structured storage probably would. But should that be necessary given we’re working with a single record?

With an xmlindex, the same query above runs in about 1 second, so is about 5x faster (0.2 sec/lookup), which is almost good enough. Is this the answer? Or is there a better way? I’m not sure why the optimizer wants to scan the code tables and index into the (one) XML record, rather than the other way around, but maybe that makes sense if the optimizer wants to use the same general plan as when the WHERE clause constraint is relaxed to multiple records.

Am I on the right path, or am I totally using the wrong approach? I thought about using XSLT but was unsure how to reference the code tables.
I’ve done the best I can constraining the main record to a single row passed to the XMLQUERY. Given Mark’s post (thanks!) should I be joining and constraining the code tables in the SQL WHERE clause too? That’s going to make the query much more complicated, but right now we’re more concerned about performance than complexity. -
Performance Problem in parsing large XML file (15MB)
Hi,
I'm trying to parse a large XML file(15 MB) and facing a clear performance problem. A Simple XML Validation using the following code snippet:
DBMS_LOB.fileopen(targetFile, DBMS_LOB.file_readonly);
DBMS_LOB.loadClobfromFile
tempCLOB,
targetFile,
DBMS_LOB.getLength(targetFile),
dest_offset,
src_offset,
nls_charset_id(CONSTANT_CHARSET),
lang_context,
conv_warning
DBMS_LOB.fileclose(targetFile);
p_xml_document := XMLType(tempCLOB, p_schema_url, 0, 0);
p_xml_document.schemaValidate();
is taking 30 mins on a HP-UX (4GB ram, 2 CPU) machine (Oracle version : 9.2.0.4).
Please explain what could be going wrong.
Thanks In Advance,
VineetThanks Mark,
I'll open a TAR and also upload the schema and instance XML.
If i'm not changing the track too much :-) one more thing in continuation:
If i skip the Schema Validation step and directly insert the instance document into a Schema linked XMLType table, what does OracleXDB do in such a case?
i'm getting a severe performance hit here too... the same file as above takes almost 40 mins to Insert.
code snippet:
DBMS_LOB.fileopen(targetFile, DBMS_LOB.file_readonly);
DBMS_LOB.loadClobfromFile
tempCLOB,
targetFile,
DBMS_LOB.getLength(targetFile),
dest_offset,
src_offset,
nls_charset_id(CONSTANT_CHARSET),
lang_context,
conv_warning
DBMS_LOB.fileclose(targetFile);
p_xml_document := XMLType(tempCLOB, p_schema_url, 0, 0);
-- p_xml_document.schemaValidate();
insert into INCOMING_XML values(p_xml_document);
Here table INCOMING_XML is :
TABLE of SYS.XMLTYPE(XMLSchema "http://INCOMING_XML.xsd" Element "MatchingResponse") STORAGE Object-
relational TYPE "XDBTYPE_MATCHING_RESPONSE"
This table and type XDBTYPE_MATCHING_RESPONSE were created using the mapping provided in the registered XML Schema.
Thanks,

Performance problem with WPF Viewer CRVS2010
Hi,
We are using Crystal Reports 2010 and the new WPF Viewer. Last week when we set up a test machine to run our integration tests (several hundred) all report tests failed (about 30 tests) with a timeout exception.
The testmachine setup:
HP DL 580 G5
WMWare ESXi 4.0
Guest OS: Windows 7 Enterprise 64-bit
Memory (guest OS): 3GB
CPU: 1
Visual Studio 2010
Crystal Reports for Visual Studio 2010 with 64 bit runtime installed
Visual Studio 2008 installed
Microsoft Office 2010 installed
Macafee antivirus
There are about 10 other virtual machines on the same HW.
I think the performance problem is related to text obejcts on a report document viewed in a WPF Viewer. I made a simple WPF GUI with 2 buttons and the first button executes a very simple report that only has a text object with a few words in it and the other button is also a simple report with only 1 text object with approx. 100 words (about 800 charchters).
The first report executes and displays almost instantly and the second report executes instantantly but displays after approx. 1 min 30 sec.
And execute in this context means that all VB.Net code runs in the compiler without any exception or performance problem. The performance problem seems to come after viewer.Show() (in the code below) has executed.
I did another test on the second report and replaced the text obejct with a formula field with the same text as the text object and this test executed and displayed the report instantly.
So the performance problem seems to have something to do with rendering of textobjects in the WPF Viewer on a virtual machine with the above setup.
I've made several tests on local machines with Windows XP (32 bit) or Winows 7 (64 bit) installed and none of them have this performance problem. Its not a critical issue for us because our users will run this application on their local PCs with Windows 7 64-bit but its a bit problematic for our project not being able to run all of our integration tests but I will probably solve this by using a local PC instead.
Here is the VB.Net code Im using to View the reports:
Private Sub LightWeight_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs)
Dim lightWeightReport As New CrystalDecisions.CrystalReports.Engine.ReportDocument
lightWeightReport.Load(Environment.CurrentDirectory & "\LightWeight.rpt")
' Initialize Viewer
Dim viewer As LF.LIV.PEAAT.Crystal.Views.ReportViewer = New LF.LIV.PEAAT.Crystal.Views.ReportViewer()
viewer.Owner = Me
viewer.reportViewer.ViewerCore.ReportSource = lightWeightReport
viewer.Show()
End Sub
Private Sub LightWeightSlow_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs)
Dim lightWeightReport As New CrystalDecisions.CrystalReports.Engine.ReportDocument
lightWeightReport.Load(Environment.CurrentDirectory & "\LightWeightSlow.rpt")
' Initialize Viewer
Dim viewer As LF.LIV.PEAAT.Crystal.Views.ReportViewer = New LF.LIV.PEAAT.Crystal.Views.ReportViewer()
viewer.Owner = Me
viewer.reportViewer.ViewerCore.ReportSource = lightWeightReport
viewer.Show()
End Sub
The reports are 2 empty default reports with only 1 textobject on the details section.

I have analysed your program and i would like to share following points for better performance of this report :
(a) Use the field Names instead of Select * or Select Single * as if you use the field names it will consume less amount of resources inside the loop as well as you have lot many Select Single * and u r using very big tables like VBAP and many more.
(b) Trace on ST05 which particular query is mostly effecting your system or use ST12 in current mode to trace for less inputs which run the report for 20-30 min so that we get an idea which queries are effecting the system and taking a lot of time.
(c) In Case of internal tables sort the data properly and use binary search for getting the data.
I think this will help.
Thanks and Regards,

IPad 1 email and performance problems ios5
Since I upgraded my iPad 1(wifi only) to iOS 5' I have been having numerous performance problems, and my email continuously sys "checking Email". I have tried restarting my iPod ith no luck. Deleting d reading the accounts woks briefly, but after 15-20 minutes the email problem ones back. The update has relly crippled my iPad.
Has anyone else had this problem? Any ideas to resolve it?
Regards,
JasonWhile Downgrading is not actually supported by Apple I found a video on You Type that walked me through it. Just do a search on You tube and you will find it. The one I used was by lizards821. His videos cover any errors you might have.
Once I reverted, I then did a restore from the backup I made when upgrading to IOS 5 and all of my apps were restored while keeping my downgraded IOS.
Good Luck, it was well worth it for me. I have the stable IPAD I love so much back again. -
Oracle Internal error while executing sys objects
Hi,
I recently restored an oracle 9i database from datafiles I received from client.
I am consistently getting the following error whenever I try to open a new sqlplus session.

After search I found some references to recreate the sys objects by running standard sqls like CATALOG.SQL, CATPPROC.SQL etc. While running these SQLs as well I am getting oracle "Internal Errors".

JSP causes serious performance problem in my EP
I have a native JSP application and running it on the EP. This application accessing a Oracle db (using oracle.jdbc.driver.OracleDriver driver).
When this db not running, my EP doesn't open any page. The EP try to connect with this db, but not get success.
I modify this application with TRY and CATCH to treat the application problem, but the EP problem continues.
In the EP Thread Overview (System Adm -> Monitoring -> Portal -> Thread Overview), I see threads (locked) about this application. To unlock this threads, I delete the par file from the Portal and re-deploy it.
When this threads is deleted, the application treat the problem (display a error message in the iView container) and EP work normally.
My questions:
1) Exists some way that the problem with this application does not cause performance problems with the EP (via code or property)?
2) Exists some property in the Config Tool where I configure the connection timeout for access the external DB?
3) Exists some way to liberate these (locked) threads of the EP (I see the page Clearing the Portal Runtime Cache - http://help.sap.com/saphelp_nw04/helpdata/en/d2/a216e1bd7b431c82fa5ff105187112/frameset.htm - but I don't know if I can use it for this)
I use EP 6.0 SP 15.

Performance tuning in objects involving Integration process (BPM)
Hi,
We are facing a performance problem in one of our objects having integration process. The messages are getting processed sequentially instead of parallel processing within the integration process. As a result, the messages are getting queued up in the queue waiting for processing. Thus by the time all messages get processed, the time taken would have been alarmingly high. There is no correlation involved in the int process. My questions are
1. Is there any performance related best practices/checklist/config steps available for BPM related implementation. If so, please furnish/provide the links if any.
2. If it is not related to BPM , but related to tuning up of the queues, please provide the guidelines for queue tune up.
3. How to ensure that the messages are processed in-parallel within BPM ?
Regards
GaneshHi,
Am not sure whether this would help you. By any chance did u use For Each instead of Par For Each.
Cos, when u use For each in an container step, all messages would be processed sequentially.
Do let me know if it helps you!

Performance and Sprite objects
I've written an application in Flex 2 that consists of
several accordions containing custom canvas objects, and it is
having performance problems.
I'm running the application within IE 6.0 under Windows 2000.
The application loads an XML file and uses the data to create
custom Sprite objects in the canvases. Each Sprite consists of two
swf images that are loaded using the Loader class, a small
rectangle created by using the Sprite graphics property, and a text
label. In addition, each Sprite is connected to one or more other
Sprites by a line drawn using the Sprite's graphics property. The
Sprites have the capability for being dragged, and for being
highlighted when clicked.
My problem is performance; these Sprites perform slower than
a similiar program that I wrote in ActionScript 2.0. From what I
understand, Flex 2.0, ActionScript 3.0, Flash 9, and the new Sprite
class are supposed to deliver greatly improved performance, but my
new application seems worse than the old one under Flash 7 using
MovieClips. The more Sprites on the screen, the worse the
performance, and the lines seem to contribute to the degradation.
There is way too much code involved to include in this
message, so I'm looking for general info. Is there some basic point
I am missing?
The performance is also degraded when triggering instances of
the Menu and Popup classes. When running the Task Manager during
the application, I've noticed that both Memory Usage and GDI
objects increase whenever I display a Menu or Popup. Both Memory
Usage and GDI objects go up and down, but there is a steady
increase in both metrics as I continue to use Menus and Popups. As
far as I can tell, I am disposing of both types of objects
properly, but it appears that their allocation is remaining in
memory.I've written an application in Flex 2 that consists of

Performance problem in loading the Mater data attributes 0Equipment_attr
Hi Experts,
We have a Performance problem in loading the Mater data attributes 0Equipment_attr.It is running with psuedo delta(full update) the same infopakage runs with diffrent selections.The problme we are facing is the load is running 2 to 4 hrs in the US morning times and when coming to US night times it is loading for 12-22 hrs and gettin sucessfulluy finished. Even it pulls (less records which are ok )
when i checked the R/3 side job log(SM37) the job is running late too. it shows the first and second i- docs coming in less time and the next 3and 4 i- docs comes after 5-7 hrs gap to BW and saving in to PSA and then going to info object.
we have userexits for the data source and abap routines but thay are running fine in less time and the code is not much complex too.
can you please explain and suggest the steps in r/3 side and bw side. how can i can fix this peformance issue
Thanks,
dpHi,
check this link for data load performance. Under "Extraction Performance" you will find many useful hints.
