Performance Problem ADF-UIX Appl. with Bea 8.1

Hello JDev & J2EE Folks,
I'm running into a performance problem with an ADF-UIX Application (JDev Version 10.1.2.0.0) under Bea 8.1. Application Server. It seems that the the same application is running at least factor 5 slower than on OC4J. I didn't experience such a difference with the older JDev9i Applications, seems to be an issue with 10g. Not done much investigation so far. Are there any ideas or suggestions out there? Anyone who had a similar problem?

Hi ,
Did you get this resolved? Can you share? Thanks!

Performance problem at bulk insert with spatial index

Hi,
I have a table with SDO_GEOMETRY.
Insert without spatial index is very fast, but with active spatial index it's very slow.
So for the first big import of data, I can drop the index, import the data and again create the index. Thats 10 times faster!
But for an already very big table that is no option.
The 10g1-Users Guide (1) says at 4.1.3 that the spatial index should be set to 'deferred', the data should be inserted and than the index should be synchronized again. That sounds very good, but I can't find this at the 11g1-Users Guide.
I tried it (11g1), but the performance is even worse than with active index!
What could be my mistake? Any hints?
Thank you,

Performance problems using WLS6.1 with the thin driver for Ora9i from OTN

Hello everyone,
Has anyone been experimenting with the thin driver for Oracle 9i under WLS6.1. I got it running, but
I get extremely bad performance when having multiple concurrent accesses. It works more or less in
single user mode. Also it seems not to support XA transactions?
When could we expect the driver from BEA to be out?
Thanks in advance!

I had done this from the very beginning, but I was still getting very bad performance under
concurrent accesses. I even followed Sree's instructions and removed the old thin driver from
weblogic.jar, but this didn't help. I am now trying to get the OCI driver for 9i running and hope
this will solve the problem.

Performance problem on a table with zero rows

I queried the v$sqlarea table to find which SQL statement was doing the most disk reads and it turned out to be a query that read 278 Gigabytes from a table which usually has zero rows. This query runs every minute and reads any rows that are in the table. It does not do any joins. The process then processes the rows and deletes them from the table. Over the course of a day, a few thousand rows may be processed this way with a row length of about 80 bytes. This amounts to a few kilobytes, not 278 Gig over a couple of days. Buffer gets were even higher at 295 Gig. Note that only the query that reads the table is doing these disk reads, not the rest of the process.
There are no indexes on the table, so a full table scan is done. The query reads all the rows, but usually there are zero. I checked the size of the table in dba_segments, and it was 80 Meg. At one point months ago, during a load, the table had 80 Meg of data in it, but this was deleted after being processed. The size of the table was never reduced.
I can only assume that Oracle is doing a full table scan on all 80 Meg of this table every minute. Even when there are zero rows. Dividing the buffer gets in bytes by the number of executions yields 72 Meg which is close to the table size. Oracle is reading the entire table size from disk even when the table has zero rows.
The solution was to truncate the table. This helped immediately and reduced the disk reads to zero most of the time. The buffer gets were also reduced to 3 per execution when the table was empty. The automatic segment manager reduced the size of the table to 64k overnight.
Our buffer cache hit ratio was a dismal 72%. It should go up now that this problem has been resolved.
Table statistics are gathered every week. We are running Oracle 9.2 on Solaris.
Note that this problem is already resolved. I post it because it is an interesting case.

Kevin,
The solution was to truncate the tableThis is not a scoop... isn't it ?
Table statistics are gathered every weekIs there any reason for that ?
If stats ran when no rows, perf can be very bad after loading data, and if stats ran when thousand rows, perf can be very bad after deleting. Perhaps can you find a more restrictive stat running ?

Performance Problems with intrinsic array multiplikation in Fortran with Su

Hello,
I found a serious performance problem in my application with intrinsic array multiplikation. Therefore I wrote a small test program to check if this a general problem or only exists in my code.
The test program (as seen below) was compiled with Sunstudio12 und Solaris 5.10 on an 64 bit Amd Opteron Machine. First with high optimization (f95 -fast -g), and the second time with out optimization (f95 -O0 -g). In both cases the intrinsic array mupltiplication had a lot of tlb and L2 cache misses (I made some test with the performance analyzer) which caused a huge increase in computation time compared to the explicit loop. In the ideal case the compiler should create the nested loops from the intrinsic statement and both functions should use exactly the same computing time.
I also tried compiling with Studio11, the problem also occurs there. Maybe its a compiler bug but I'm not sure.
Greetings
Michael Kroeger

do i=0,ni

enddo
enddo
enddo
end subroutine withloop
end program

I will try the large pages, but what me puzzles is, that the intrinsic function has cache misses, but the loop function has not. All documentation says, that the compiler would expand the intrinsic function into 3 nested loops, so that both functions should be essential the same (and the compiler says it has created 3 loops from the intrinsic). Since they are not the same, this is a severe problem.
I have a fairly large code for high performance simulations, and this intrinsic functions are a significant bottle neck. If it is not a compiler bug, I would have to rewrite all intrinsic functions into loops.

Hi,
The reason why you are seeing this exception is because there is a mismatch between the version of the WLPM API used by the portlets, with the version of the service that you have installed on you Domino server.
To explain a little, there are two sides to the API that is used to communicate with Lotus Domino:
1) the Java API side (used by the portlets that you have installed in the portal)
2) the Domino Service side (installed as a DSAPI filter in the HTTP task of a Domino Server)
Each Java API jar and Domino Service Executable are branded with a version number, which in your case does not match because the portlets came with one version of the Java API, and you have installed a non-matching version of the service on the Domino Service side (you probably extracted the executable for the service installation from the "BEA Personal Messaging API 4.3" bundle or installer).
The solution for this is to:
1) uninstall the Domino Service that you have plugged into the domino service
2) extract the Domino Service installer which was included with the portlet bundle. This is located in the "Program Files\compoze\groupware_portlets_bea-2.5\8.1\service\domino" directory if you ran the portlet installer, or in the "groupware_portlets_bea81-noinstall-25\groupware_portlets_bea-2.5\8.1\service\domino" directory if you used the "no-install" zip file.
As a tip, to quickly check whether the versions of the service and Java APIâ€™s that you are using are matching, perform the following steps:
1) hit the domino server with the following URL and notice the "service version": http://domino_service_url:http_port/compoze.czdo. This should be something like "Service Version: 3.6.102"
2)in your portal application (or in the portlet install bundle), open the harmony_portlets.jar file with winzip, then find the "compoze_products_information.properties" file. In this file, notice the "product.domino" version (e.g. product.domino = 3.6.102)
3) the two versions you have inspected must match in order for the connection between the portlet and service to succeed.
If you have verified that the "service" version and "java API" version (located in %portal_app_dir%/APP-INF/lib/harmony_portlets.jar, and you are still getting the exception, it is likely that there is a "harmony_portlets.jar" that included an old version of the Java API located somewhere in the portal server classpath. In this case, make sure that the only harmony_portlets.jar in the classpath is the one that was included with the portlet bundle that you have installed.

IOS 4.2.1 have performance problem?

I use iOS 4.2.1 on iPhone 4. While many background applications run, my iPhone4 is very slowly. I think iOS4.2.1 have performance problem. So, Apple should release maintenance release for iOS 4.2.
Do you think?

Yes, I do not try it but I guess so. If I stop background applications, I can get confirmable iPhone life.
According to apple, "task manager" must be unnecessary for iPhone. Memory control for iOS4.2 have is not good.

WAS JAVA 640 engine is giving performance problems.

Hi,
We are facing the performance issues in WAS java 640 SP19 engine. Pages are taking much time to load.
Kindly suggest if there anything do with jco connection parameter changes and recommended values. Is there any parametes to check at the backend system level.
WAS version: 640, SP19
OS : SUN 5.9
Oralce: 9.2.0.8
Thanks,
Hareesh

Hello Hareesh
You should find the root cause of your performance problem first.
Start with checking the server (cpu, memory, paging) and by checking if your portal runs on the recommended parameters (check oss notes).
A killer for portal performance is when you have a lot of paging going on, make sure the portal has enough extended memory available to avoid any paging.
If those don't give a result, you can still analyze garbage collection logs with third party tools.
Check if heapdumps are being generated and analyze them.
Once those checks are done, I would recommend installation of Sol Man Diagnostics + Wily Introscope so you get a better view on what is going on and troubleshoot further from there.
Kind regards
Tom

Performance problems with Leopard 10.5.1

Hello,
I use an iMac 24 Alu 2,8Ghz and upgraded to Leopard. There are some major performance problems and bugs in the recent version of Leopard:
1. While accessing USB devices, the display speed, windows moving, animations etc. slow down
2. Adobe CS3 Photoshop 10.01 and Flash CS3 are sometimes extremly slow. I tried the recent demo packages from Adobe:
2.1. The Photoshop dialogue "save for web" slows down the system completly, and this problem stays when quitting Photoshop. A restart is neccessary then.
2.2. Flash CS3 movie preview is very slow and stuttering. It's so slow you cannot imagine how the real movie flow will be.
2.3. Recent Flash Player 9,0,115,0 with hardware acceleration enabled doesn't really work with QuartzGL enabled Leopard: The movies slow down a lot. Try www.neave.tv for example.
3. Safari, Mail and other bundled software hang sometimes. You have to force quit them then. It doesn't matter whether QuartzGL is enabled or not. This especially happens to my system if it is online for some hours.
4. A lot of Apple applications doesn't seem to work with 2dextreme enabled. Why this? Apple supporters told me in Leopard there will be a much better 2dextreme support. Also Quartz2dExtreme in OSX 10.4 worked with all applications and i guess it's the same feature like "QuartzGL" in Leopard. So Leopard isn't finished here. It would be nice if Apple could make it's own software QuartzGL compatible.
5. Very often the desktop slows down or lags. This is the main reason I often still witch to Windows XP PC to do work in a faster, less annoying way.
6. Safari crashes randomly sometimes. It is unstable still. Also it crashes more often if you resize/move the window a lot, so I guess it is a graphics extension-related problem.
I hope you people from Apple will fix these annoying points and optimize your new system in the next update release.
Best regards

Thanks for you answer. I repaired in the way as described above. There were some errors, some file index was wrong (don't remember exactly the phrase), now the DU reports the partition was successfully repaired / the volume appears to be ok.
The crashes in Safari are gone, but all other described problems still exist. Adobe CS3 is not really usable for me.
By the way, in iMacSoftwareUpdate 1.3, which was replaced by OSX 10.5.1 update, there is one extension called AppleVADriver.kext that does not exist in the OSX 10.5.1 update. Is it an important extension?

Performance problem with Mavericks.

Performance problem with Mavericks. My Mac is extremly slow after upgrading to Mavericks. What can i do to solve that?

If you are still experiencing slow down issues, it maybe because of a few other reasons.
Our experience with OS X upgrades, and Mavericks is no exception, is that users have installed a combination of third party software and/or hardware that is incompatible and/or is outdated that causes many negative performance issues when upgrading to a new OS X version.
Your Mac's hard drive maybe getting full.
Do you run any antivirus software on your Mac? Commercial Antivirus software can slow down and negatively impact the normal operation of OS X.
Do you have apps like MacKeeper or any other maintenance apps like CleanMyMac 1 or 2, TuneUpMyMac or anything like these apps, installed on your Mac? These types of apps, while they appear to be helpful, can do too good a job of data "cleanup" causing the potential to do serious data corruption or data deletion and render a perfectly running OS completely dead and useless leaving you with a frozen, non-functional Mac.
Your Mac may have way too many applications launching at startup/login.
Your Mac may have old, non-updated or incompatible software installed.
Your Mac could have incompatible or outdated web browser extensions, plugins or add-ons.
Your Mac could have connected third party hardware that needs updated device drivers.
It would help us to help you if we could have some more technical info about your iMac.

ADF UIX doSelect override with PL/SQL fails to allow insert

I've been trying to create an ADF-UIX web app for simple insert/update/delete of records to a table.
The schema simply has 2 tables - master and detail where the detail pk is made up of the master id and a start date:
CREATE TABLE master (
id NUMBER NOT NULL,
name VARCHAR2 (10) NOT NULL,
CONSTRAINT pk_master
PRIMARY KEY ( id ));
CREATE TABLE detail (
id NUMBER NOT NULL,
start_date DATE NOT NULL,
name VARCHAR2 (10) NOT NULL,
description VARCHAR2 (100),
CONSTRAINT pk_detail
PRIMARY KEY ( id, start_date ));
ALTER TABLE detail ADD CONSTRAINT d_m_fk FOREIGN KEY (id) REFERENCES master(id)
This works fine when I create it in a similar manner to that described in the "Complete ADF UIX Application ..." tutorial doc.

I then tried to override the ADF doSelect and doDML methods as outlined in ADF_BC_StoredProcedures.zip example app allowing me to use PL/SQL stored pkg for dml.
http://www.oracle.com/technology/sample_code/products/jdev/10g/ADF_BC_StoredProcedures.zip
On trying to insert a new row my web app now fails with a null pointer exception when I press the Submit button. The app calls doSelect->handleStoredProcSelect which fails to get the value of a column.
void handleStoredProcSelect() {
CallableStatement st = null;
try {
String stmt = "BEGIN test_api.do_select(?,?,?,?,?); END;";
DBTransaction tr = getDBTransaction();
st = tr.createCallableStatement(stmt,1);
## This line works, I'm guessing because the value is populated from the master record I've selected in the form ...
st.setLong(1,getTestId().longValue());
##FAILS HERE st.setDate(2,getStartDate().dateValue());
Update,delete still work ok. And if I run the test app (right click on AppModule and select Test) all works ok.
I'm not sure why doSelect is called on an insert so I commented out:
doSelect
handleStoredProcSelect
handleStoredProcLock
compareOldAttrTo
Web App now lets me insert as expected.
So finally ....my question is:
Whilst the app now works does commenting out the doSelect leave me open to problems I haven't thought off
and if not if you did want to use it how can you allow inserts?
Any thoughts or similar experiences appreciated ...

I've been trying to create an ADF-UIX web app for simple insert/update/delete of records to a table.
The schema simply has 2 tables - master and detail where the detail pk is made up of the master id and a start date:
CREATE TABLE master (
id NUMBER NOT NULL,
name VARCHAR2 (10) NOT NULL,
CONSTRAINT pk_master
PRIMARY KEY ( id ));
CREATE TABLE detail (
id NUMBER NOT NULL,
start_date DATE NOT NULL,
name VARCHAR2 (10) NOT NULL,
description VARCHAR2 (100),
CONSTRAINT pk_detail
PRIMARY KEY ( id, start_date ));
ALTER TABLE detail ADD CONSTRAINT d_m_fk FOREIGN KEY (id) REFERENCES master(id)
This works fine when I create it in a similar manner to that described in the "Complete ADF UIX Application ..." tutorial doc.

Populate Primary Key with DBSequence in ADF UIX page

I have a table with a trigger, so that the primary key is populated by DBSequence. My problem is, I open a ADF UIX Input Page to create a row for my table. The field of the primary key is populated by any number but not with the logical sequence number. This number appears later, when I look at a row list. So the correct number is in the database but how can this already appear on my input page???

You have to drop the trigger.
Then make sure you have the Id field of your entity of type Sequence.
Then go to your entity class and override the Create method.
protected void create(AttributeList attributeList)
    super.create(attributeList);
    SequenceImpl s = new SequenceImpl("YOUR_DB_SEQUENCE_NAME", getDBTransaction());
    Number sVal = s.getSequenceNumber();
    setId(new DBSequence(sVal));

Making a delete commit automatically with ADF BC, Struts and ADF UIX

I'm trying to create a delete action that commits to the database automatically using ADF Business Components, Struts and ADF UIX.
I have a browse page from which the user can view all records in the table, and perform edit, create and delete actions on the data.
When the user selects a record and clicks edit they are taken to a screen where they can amend the details of that record. Create works in a similar way, but the create action on the view object is invoked before taking the user to the edit page (this is done by linking the browse page to an ADF DataAction (bound to Create) on the Struts page flow diagram, and then linking the ADF DataAction to the edit page).
When the user clicks submit on the edit page, the container follows a forward from the edit page to an ADF DataAction bound to the Commit method, and then from there a forward back to the browse page.
This seems to work fine for edit and create, but when I try to do something similar for delete, it behaves unpredictably - sometimes the delete is committed to the database, sometimes not.
To be more specific, the way I have tried to implement the auto commit delete is as follows:
There is a UIX submitButton on the browse page called Delete. When clicked, this button triggers an event, which is caught by an event handler inside the page. The event handler causes the UIX servlet to take a forward to an ADF DataAction bound to the Delete method on the relevant view object. It thens follows a forward from the previously mentioned DataAction to another ADF DataAction bound to the Commit method for the application module. There is then a forward leading back to the browse page.
Has anyone else encountered similar problems?

did you figure this out?

ADF UIX 2.2.20 + ADF BC: russian locales problem

Hi all,
We are using Oracle 9.2, ADF UIX 2.2.20, ADF BC on JDeveloper 10.1.2.1.0
Tables of business entities have secondary field "Author". This field contains the name of a user, who has changed data in the table. After authorisation the name of user is stored in httpSession, and put into table using uix code:
<set target="${bindings.Author}" property="attributeValue"
value="${sessionScope.loginName}"/>
Some of users have russian letters in their names. Sometimes (about 1200 of 70000 rows) during commit russian letters are "lost" and replaced by "?" sign in Oracle table.
This problem happens on Oracle iAS 10g and TomCat 5.5.12 application servers, and on HP-UX and Linux RH.
I found topic
Re: Form Auth and Russian Language
and message from Jonas there, but link doesn't work//
Could anyone give an idea of how to solve this problem?
thanks,
Renat

Dear Sir...
i faced a similar problem with the arabic charactors. What you should check is two things:
1- The database charactor set should support russian.
2- The encoding of the pages in JDeveloper should support russian.
if you open any uix page and look at the source you probably will find the encoding equal to windows-1252. you should change it to russian encoding (which i do not know what it is).
you should install the russian language in windows, reinstall jdeveloper, then change the encoding of jdeveloper to support russian.
i hope this helps.
best regards
