Performance Issues due to Loading of ADF/JClient View Objects

Hi,
I developed a two-tier ADF/JClient application.
When the ADF/JClient application opens for the first time, there's a big delay
However opening it subsequently, takes less than half of the time to open the screen.
I think it might the xml files of different view objects which the framework loads for the first time, and thus takes a lot of time. And after that, the time to open the application reduces.
We have around 200 view objects in our application. Can this be the reason?
If yes, then can we load the view objects before ahead, or can we just load them at the very time they are requested ?
Thanks,
Makrand Pare

Hi Makrand,

"Limiting Fetching of Business Components Attributes in ADF Swing
http://www.oracle.com/webapps/online-help/jdeveloper/10.1.3/state/content/navId.4/navSetId._/vtTopicFile.developing_jclient_applications%7Cjui_plimitingfetching%7Ehtml/
Note: In local mode deployment (the client and Business Components reside in the same VM), the fetching of attribute properties is not supported.
You can optimize startup time for a Business Components client application and the remotely deployed Business Components by specifying the list of view object attributes that your client uses. If you create a project without the metadata, by coding to the API, you will want to add fetchAttributeProperties() to the bootstrap code of the client forms with a list of only the attributes used by the form. Without this method call, your client form would fetch all control hint properties (including the attributes format and label for example) for all the attributes of the named view objects in the application module, in a single network roundtrip.
For example, when you do not intend to use all the attributes of the ADF Swing form's bound view object, with the fetchAttributeProperties() method, your ADF Swing form fetches only the information required to layout your forms, while ignoring the attributes you do not require.
Note: In local mode deployment (the client and Business Components reside in the same VM), the fetching of attribute pro
Calling fetchAttributeProperties() will prevent property methods such as getFormat() or getLabel() from being called on the Business Components attribute definition whenever the form is created."

Hi shubhu,
I just analyzed your partial Thread Dump data, the problem is that the ajax4jsf framework ResponseWriterContentHandler triggers internally a new instance of the DocumentBuilderFactory; every time; triggering heavy IO contention because of Class loader / JAR file search operations.
Too many of these IO operations under heavy load will create excessive contention and severe performance degradation; regardless of the OS you are running your JVM on.
Please review the link below and see if this is related to your problem.. This is a known issue in JBOSS JIRA when using RichFaces / ajaxJSF.

Cisco ASR 1002- performance issue due to access list

Hi,
We are planning to implement inbound access-list to block subnets from particular country. Since the subnets are not contiguous, we have about 16000 lines of acl entries.
I want to know, would there be any performance or latency issues after applying 16k lines of acl?
Is there a good document where I can read more about ACL limitations and performance issues on ASR.
This is for ASR1002, running IOS-XE 15.3(1)S1.
Thanks

Avoiding performance issue due to loop within loop on internal tables

Hi Experts,
I have a requirement where in i want to check whether each of the programs stored in one internal table are called from any of the programs stored in another internal table. In this case i am looping on two internal tables (Loop within a loop) which is causing a major performance issue. Program is running very very slow.
Can any one advise how to resolve this performance issue so that program runs faster.
Thanks in advance.
Regards,
Chetan.

Forget the parallel cursur stuff, it is much to complicated for general usage and helps nearly nothing. I will publish a blog in the next days where this is shown in detail.
Loop on loop is no problem if the inner table is a hashed or sorted table.
If it must be a standard table, then you must make a bit more effort and faciliate a binary search (read binary search / loop from index exit)
see here the exact coding Measurements on internal tables: Reads and Loops:
/people/siegfried.boes/blog/2007/09/12/runtimes-of-reads-and-loops-on-internal-tables
And don't forget, the other table must not be sorted, the loop reaches anyway every line. The parallel cursor requires both tables to be sorted. The additional sort
consumes nearly the whole advantage of the parallel cursor compared to the simple but good loop in loop solutions.

[SOLVED] ADF BC : View Object "second level" Entity reference issue

hi
If I insert a row in a View Object that uses "two levels" of Entity references, the attributes of the Entity on the "second level" don't get a value.
Consider these tables:
MY_ROW (MY_ROW_ID, MY_ROW_STUFF, MY_ROW_LU1_ID)
MY_ROW_LU1 (MY_ROW_LU1_ID, MY_ROW_LU1_STUFF, MY_ROW_LU1_LU1_ID)
MY_ROW_LU1_LU1 (MY_ROW_LU1_LU1_ID, MY_ROW_LU1_LU1_STUFF)
Where MY_ROW.MY_ROW_LU1_ID is a "look-up" in MY_ROW_LU1 and MY_ROW_LU1.MY_ROW_LU1_LU1_ID is a "second level look-up" in MY_ROW_LU1_LU1.
I created default Entities and Associations on these tables and a View Object that uses all 3 Entities (MyRow as Updatable, MyRowLu1 and MyRowLu1Lu1 as Reference).
See example code in
http://verveja.footsteps.be/~verveja/files/oracle/ViewObjectEntityReferenceIssue-v0.03.zip
(contains no Java code, all out-of-the-box ADF BC)
problem scenario:
If run the MyRowService Application Module in the Oracle Business Component Browser and "open" the MyRowViewAll View Object instance, I get the rows and their related "look-up values".
If I click the "Insert a new record" button and fill out values for MyRowId, MyRowStuf and MyRowLu1IdEntity, I only get "look-up" values for the "first level". While the "second level" stays empty.
For example, a MyRowLu1IdEntity of "2003" gives a MyRowLu1Stuff value of "2003 stuff", but no value in MyRowLu1Lu1Stuff.
What am I doing wrong? What should I change to also get a value in the "second level" MyRowLu1Lu1Stuff attribute?
many thanks
Jan Vervecken

Jan,
If you create a view object on Emp and Dept, with Dept as a reference entity, you might choose to build the view object to only include the:
Emp.Empno (required, since it's the PK of Emp entity usage)
Emp.Ename (included since you want to show the ename)
Dept.Deptno (required, since it's the PK of the Dept entity usage)
Dept.Dname (included since you want to show the dname)
The wizard enforces the inclusion of the required attributes above.
When you run this view object, a join is performed and you see the reference data.
Now, if you want to allow the user to UPDATE the reference data, you need to add one more attribute to the list of attributes:
Emp.Empno
Emp.Ename
Emp.Deptno (To allow user to change Deptno employee belongs to)Dept.Deptno
Dept.Dname
At this point, not only is the join performed for you, but the ADF BC reference mechanism reacts to any modification of the Emp.Deptno attribute, correctly showing the reference information for that new foreign-key-referenced department (even before commiting and requerying, at which time the SQL join would pickup that correct, related information).
The "second level" problem you describe in this thread is simply the same issue described here as a master/first-level-detail situation, taken to its logical next step. If you want the end-user to be able to change the second-level detail to which the first-level-detail is associated, you need to include the first-level-detail's foreign key attributes in the view object's select list. Otherwise, there is no foreign key attribute whose value-change event the framework can react to in order to coordinate the related reference data in the row.
I've blogged a link to a working example of a four-level reference information view object here:
http://radio.weblogs.com/0118231/2007/05/09.html#a818
based on the HR schema.

Performance issue in linux while using set with URL object

Hi,
I am facing performance issue while using Set(HashSet) with URL object on linux. But it is running perfectly on windows.
I am using
set.contains(urlObject)
Above particular statement is taking 40 sec on Linux, and only a fraction of ms on windows.
I have checked the jre version on both OS. It is the same version (jre6)
on both the OS.
Could anyone please tell me what is the exact reason, why the same statement is taking more time on linux than windows.
Thanks & Regards
Naveen

I believe the URL hashCode/equals implementations have some /tricky behavior which involves network access in order to run (doing hostname lookups and the like). you may want to either use simple Strings, or possibly the URI class (i think it fixed some of this behavior, although i could be wrong).The second new thing I have learned today. I was wrong in reply # 1 because looking at the URL code for 1.6 I see that the hash code is generated from the IP address and this has a lazy evaluation. Each URL placed in a HashMap (or other hash based collection) requires a DNS lookup the first time the hash code is used.
P.S. 40 seconds does seem a long time for a DNS lookup!

ADF - Multple View Objects in one ADF table - Jdeveloper 11g

Hi,
I'm using Jdeveloper 11g, is there a way to use multiple view objects in one ADF table? And if so, do you have an example?
In my case the view objects are not based on a database table they were created based on an ESB wsdl, one is for person and one is for address.
Any information or pointers you could provide would be appreciated.
Thanks!

Hi,
That would be a good solution, however, I'm supposed to see if there is a way to use the VOs that were created for person and address. Even better if the solution requires little coding.
Is it possible to combine these two VOs into a single VO to use with an ADF table or to use both of them in a single table? Or is there some other solution that would enable me to use the person and address VOs in a similar manner?
Thanks!

ADF BC View Objects: Disappearing where clauses

Playing around with the 11g Technical Preview I find out that sometimes the where clauses - added to View Objects by means of the new "Join Type" field in the VO-editor UI - disappear.
I'm not able to reproduce exactly and "on demand", but it seems to happen when the sources of more than one View Object are open simultaneously and/or the XML definition of a View Object is edited directly on the Source-tab.

Today I succeeded in reproducing:
Two tables:
TAB_MASTER:
ID NUMBER NOT NULL
DESCRIPTION VARCHAR2 NOT NULL
TAB_DETAIL:
ID NUMBER NOT NULL
MASTER_ID NUMBER NOT NULL
DESCRIPTION VARCHAR2 NOT NULL
TAB_DETAIL.MASTER_ID is a foreign key referencing TAB_MASTER.ID.
Steps to reproduce:
1. Generate default ADF BC objects from database tables.
2. Open definition of TAB_DETAIL View Object.
3. Go to the Entity Objects tab
4. Add TAB_MASTER Entity Object to the Selected Entities Objects. Association and Join Type are filled in automatically.
5. Go to the Query tab and go to SQL tab in de Property Inspector. Where clause is filled.
6. Go to the Attributes tab and click Add from Entity...
7. Add TAB_MASTER.DESCRIPTION attribute.
8. Again, go to the Query tab and go to SQL tab in de Property Inspector. Where clause is still filled.
9. Go to the Attributes tab and select MASTER_ID attribute.
10. Click icon to add List Of Values
11. In List Of Values dialog add View Object TAB_MASTER and add the correct pairs of List Return Values for the ID and (MASTER) DESCRIPTION attributes.
12. After completing the List Of Values dialog go to the Query tab -> SQL tab again. The where clause added to join the Entity Objects (see step 5.) is cleared, resulting in a wrong SQL statement for the View Object.

Connecting ADF BC view object w/ param to a JSF Table?

I'm brand new to JDev so this is probably an easy one, I'm still trying to grasp some of the concepts: I have created an application module that has one view object containing a simple parameterized query (page is a simple search form - user enters keywords - I pass keywords to database and return results.) This Data Control shows up in the Data Control Palette and I am able to associate this with a table on the JSF page. Where I'm struggling is how / where do I tell JDev to bind the query parameter? In the examples from the help files, they show in the Data Control Palette a method with parameters. My Data Control Panel just shows the application module labeled as a Data Control with no parameters? In the Application Module (where I have defined the parameterized SQL stmt), in the Client Interface menu item, there are no methods available. Do I need to create the method even if I don't want to override the default functionality? Any help appreciated.
Also, many of the tutorial and examples look like they use the EJB/Toplink approach - are there good examples or tutorial for using ADF BC and ADF Faces?
Thanks. BTW - this product looks awesome so far! I was using myEclipse - this product is light years ahead.

This new 10.1.3-production JSF/ADFBC tutorial covers a lot of ground and includes an example of building the search page that you're trying to build, too :-)
http://otn.oracle.com/obe/obe1013jdev/masterdetail_adf_bc/master-detail_pagewith_adf_bc.htm
The trick is noticing that a View Object with named bind parameters includes an additional built-in operation in its "Operations" folder called ExecuteWithParams. Dropping this operation onto your page gives you the choice of creating a "Parameter Form" for your VO's bind variables. If you then drop the VO as a readonly table to the same page and run the page, you are done. :-)
Try to do that in Eclipse in two drag-drop operations! ;-)
It warms my heart to hear you say that about JDeveloper versus Eclipse... Really makes my day!

ADF Join View Object

we have a Join View Object joining Customer and Order tables. The Output in ADF table is like this
CustomerName------------OrderID
John------------------------------------1
John------------------------------------2
John------------------------------------3
Tom------------------------------------80
Tom------------------------------------81
Tom------------------------------------82
We need to show the out but as
CustomerName------------OrdersPlaced
John------------------------------------1,2,3
Tom------------------------------------81,82,83
Please suggest how we can acheive this
Thanks
Edited by: user11922045 on Oct 19, 2010 2:53 PM

Our requirement is similar to a Order - OrderDetail example, (where the number of details many times wont exceed 3)
The Order table has just the Order number and some name... and Order detail has order item, price and date detail item requested ..
So we just need to show the list of Order and for each order( the details..item no, item, price, date time req)..
As you can see we can fetch it in one single query..
I can't ask the user to click on the Order number/name to see the Order details in adifferent table every time.
Typically when i was using java.. i used to populate the details into the Order VO as an ArrayList of Order Items. w could delete just one detail/ as well as a complete Order all together.
Please suggest.

Programmatically populate ADF BC view object based on user's JAZN roles

I currently have a ADF BC read-only view object that is based on an sql query.
I would like to assign values to the bind variables based upon the user's JAZN
roles. My problem is that I am uncertain how to obtain the roles the user has.
Any help would be appreciated.
Thanks,
Kenrick

I do believe this topic is discussed in detail in the 4GL Developer's Guide. Section 30.8 describes everything how to obtain user info programatically. Aside from pointing you in a direction that will get you where you need to be, I can't be of much help. I'll be crossing that hurdle in the coming months.
Download the guide from this page:

Good Luck,

Performance issue due to column formula and filters

Hi,
I am facing strange issue with performance for my OBIEE reports. I have two sets of reports Static and Dynamic. Both runs against same tables. The only difference between these reports is that the Static reports would run against all the data for given aggregation level e.g. Year, Month, Date and so on. Where as for Dynamic one I have range prompts to filter data. Other difference is that I have a column formula for one of the column in the Dynamic report, which is nothing but Go URL to show another page with certain parameters.
The static report takes around 14-15 Seconds where as the Dynamic one takes around 3.5 min. The amount of data and range is same here. From the logs I could see that for the Static reports, i.e. reports without filters it applys group by at SQL level where as it is not doing so for the dynamic one. Is this expected ?
Second issue is, even if I say remove the filters and just have report with column formula in one and no formula in other there is significant time difference in the processing at Presentation service layer. Again this is taken from the log. it takes 8 second to get data from DB but shows almost 218 Seconds as response time at Presentation layer.
Below are conceptual details about table and reports -
Table 1 (It is date dimension) : Date_Dim
DateCode Date
Day Number
MonthCode Varchar2
YearCode Varchar2
Table 2 (It is aggregate table at year level) : Year_Aggr
DateCode Date (FK to Table1 above)
Measure1
Measure2
Measure3
Measure4
Measure5
Report 1
Date_Dim.YearCode | Year_Aggr.Measure1 | Year_Aggr.Measure2 | Year_Aggr.Measure3 | Year_Aggr.Measure4
Report 2
Dashboard Filter : Dimension1 | Dimension2 | Year Start | Year End |
Date_Dim.YearCode | Year_Aggr.Measure1 | Year_Aggr.Measure2 | Year_Aggr.Measure3 | Year_Aggr.Measure4
Column formula for Date_Dim.YearCode is something like :
'<a href="saw.dll?Dashboard&PortalPath=somepath and parameters target=_self>' || Date Dim"."YearCode" || '</a">'
Filters :
Dimension1 is prompted...
Dimension2 is prompted...
cast("Date Dim"."YearCode" as Int) is greater than or equal to @{Start_Year}
cast("Date Dim"."YearCode" as Int) is greater than or equal to @{End_Year}
Note : I need to apply cast to int as column is varchar2, legacy problem.+
How can I fix this? Am I missing something? In the result of report2 the DB SQL doesn't show the year in where thought it is displayed in the logical sql.
Let me know if anybody had faced this and have fixed. Or suggetion to make changes to fix this.
Thannks,
Ritesh</a>

Hi Ritesh,
I think you right about the root cause of your problem. The first request does the group by in the database which returns fewer records to the BI Server for processing. The second request does not do the group by and sends significantly more records back to the BI server forcing it to do the group by. Compound that with the fact that pivot table views are relatively expensive computationally and that explains the difference between the execution times.
Assuming that the execution time of the first report is satisfactory, I would recommend you try to experiment with a few settings to see if you can get the second report to do the group by in the database.
Are the two filters identical except for the following conditions?
cast("Date Dim"."YearCode" as Int) is greater than or equal to @{Start_Year}
cast("Date Dim"."YearCode" as Int) is greater than or equal to @{End_Year}
Best regards,
-Joe

Performance issue due to RFC calls. (R/3 to R/3 system)

Hi,
My application face serious performance problem because of RFC calls (R/3 system to R/3 system).
1)is there any transaction code for doing performance analysis on RFC calls in R/3 system?
2)How far large volume of Data Transfer (mainly due to internal tables) in a RFC call affects the performance? is there any limit for data transfer size at a time in a RFC call? if so how to calculate for best performance?
Thanks and regards,
Prakash.

Hi Andreas,
Suppose an RFC enabled Fm having an internal table as importing parameter.During execution of this Fm with 4000 enteries for the internal table results in performance degrading.is there any way to improve the performance?.
Thanks and regards,

SAP MaxDB 7.7.07.16 - performance issue due to IOWait(R) task

We are running MaxDB 7.7.07.16 unicode in a non SAP environment (is basis for a web application).
Database Server has 4 Cpu's, 8 Gb RAM, operating system Debian-Linux 6.0.
We have some performance problems in not regular periods of time.
The performance problem occurs for a time frame between 3 and 15 minutes and blocks more or less the complete system.
After a long phase of checking and evaluating possible issues, we think that we are very near to the issue.
We identified the database tasks
- TblPrfC - Prefetch Table Coordinator:
- PrefPag - Prefetch Pages
having the current state "IO Wait (R)".
As long these tasks are in state "IO Wait (R)" the users (at the web application) gets awful slow respond times on their queries.
On 9th of April 2011 we changed the DB parameters:
- ReadAheadTableThreshold old 0 => new 128
But today we got the same performance problem again.
If you have any hints or tips, you're welcome!
Best regards
Hannes

Hello Hannes,
ok brief but hopefully usefull answer to your post:
- if the database I/O generated by SQL statements alone brings the system to a grinding halt, then your storage system is undersized. How should it be able to handle additional I/O, e.g. for backups if it isn't capable to handle the standard I/O?
- the prefetching tasks are used to speed up large scan operations. So, the next thing to do here is to find statements that perform table scans and check whether or not these can be tuned to KEY or Index accesses
- As a workaround, I would propose to increase the value of ReadAheadTableThreshold to, say, 500, so that the prefetching is done only for really large scans.
regards,
Lars

Performance issue due to localization code in SSRS 2008

The reports I am working on consist lot of data and all the customers use it frequently.
Report title and columns are localized by expressions .
This takes long time for report rendering and exporting to csv. When I test without the localization code it doesn't take that long .
Can someone help me to optimize the report. SSRS 2008 R2
Archana

Hi Archana,
In Reporting Services, the total time to generate a reporting server report (RDL) can be divided into 3 elements:
Total time = (TimeDataRetrieval) + (TimeProcessing) + (TimeRendering)
TimeRendering means the number of milliseconds spent after the Rendering Object Model is exposed to the rendering extension. It includes the Time spent in on-demand expression evaluations (e.g. TextBox.Value, Style.*). So it is make sense that the report
with localization code takes longer time.
Besides, we can improve the report performance form other aspects. For example, we can add filter, sorting and aggregation in dataset query, because filter, sort, and aggregation is more efficient on the data source than during report processing. For more
details about report performance, please refer to the following article:
http://technet.microsoft.com/en-us/library/bb522806(v=sql.105).aspx
If there are any other questions, please feel free to ask.
Thanks,
