ADF UIX WebStart - large memory footprint

Hi everyone,
I am running a three-tier model jclient app with java webstart. java sdk 5.0 with jvm 5.0 - it creates a large footprint and then it says no more memory left to allocate to the app.
i looked at if the jvm was the cause but i am using java hotspot virtual machine. now what i am wondering is where the problem is? is it the model .... etc ?
Any help would be appreciated. Thanks!

Hi there,
This observation may be coming little late to be of use to you. But, we thought we'd post it here for others benefit.
We've encountered similar situation with our ADF application. In the end, the following tweaking helped reduce the heap size and brought back our app's GUI performance.
1. Added the following options to Sun JDK.
-XX:SoftRefLRUPolicyMSPerMB=100 -XX:+ParallelRefProcEnabled
This did the magic. Over and above this, we have also tried the following option setting to tune ADF Security, but it didn't seem to give any further improvement.
-DUSE_JAAS=false -Djps.policystore.hybrid.mode=false -Djps.combiner.optimize.lazyeval=true -Djps.combiner.optimize=true -Djps.authz=ACC -Djbo.debugoutput=silent
2. Alternatively, we also tried JRockIt JVM and interestingly enough, JRockIt handled the soft references clearing very well out of box. No tweaking was required on this.
We suspect this could an issue with configuration of security in our app. As of now, we are not sure yet. But, we have a temporary workaround.

Lightroom's large memory footprint

After massaging many pictures in "develop" mode, the system began to become very slow (like locking up for 30 seconds). I opened process explorer and found LightRoom was consuming 1.8Gig of virtual memory and had a working set of about 1.2Gig. This seems quite excessive for general photo editing. I'm really only performing simple adjustments like color and contrast.
I closed down Lightroom and restarted it, and it then worked fine again for another 50 or 60 pictures, at which time slowness occurred again, and the memory footprint was up again. Now that I know what to expect, I'm shutting LR down every 30 pictures or so to avoid the excessive memory consumption.
I suspect there is a memory leak or creep in LR.
I have a machine with 4Gig of RAM, running Vista Ultimate.

EricP,
LR does "accumulated background work" when nothing else is going on, esp if you have the Library set to All Photos. Also it appears that LR is very sensitive to where the pagefile(s) are located and their size. I only can speak to XP Pro though. Vista is a different animal. You might try putting a controlled size [1.5 RAM size for both Min and Max values] on both [or more] HDs you have. Also set the system to keep as much of the Kernel in RAM as possible and set the system to optimize for Applications. Those changes helped me. If they can be accomplished in Vista, they may help also.
Good luck and keep us informed if you get any fixes working.

Extremely Large Memory Footprint under Linux

I have not experienced this problem as I don't use linux regularly but a friend of mine has dismissed java as too slow because of this. He says that after he launches Forte or JBuilder (both java apps) they take about 500 MB of RAM. I know Forte is a memory hog but something is very wrong here. He says that he's using IBM's JRE 1.3.1 and some debian distro of linux.
Also, he said that he found info on java object "headers" each taking up a huge amount of memory. Plain java objects take only 8 bytes of memory and I've never heard of this header business before. This is the main reason I posted in the advanced forum.
Has anyone seen this type of problem before? I have no problem running java apps on windows (the performance is very good) and I'm assuming many people are running it successfully on Linux as well. Any info on this is much appreciated.
Thanks.

Your friend is incorrect. The typical JVM footprint in Linux is not what he thinks it is...
Part of the "problem" is the way Linux reports threads in CLI programs like ps and top. If you look at the output from those programs, you'd think the JVM is eating you alive - but it's not. I have 512Mb of memory and I constantly run one JVM for a small home control client, not to mention firing off an IDE to work/test in - with no memory problems whatsoever.
For example, I just started NetBeans 3.3.1 up while I was typing this and "top" reports this (sorted by memory usage):
PID USER     PRI NI SIZE RSS SHARE STAT %CPU %MEM   TIME COMMAND

Memory footprint is HUGE

I just wanted to see if anyone else has a concern with the memory footprint and when/if this will be addressed. We have an ADF web app and now when we try to run under jdeveloper 11G the combination of jdeveloper and the weblogic java process is over 900M and grows when you do any clicking around. Under the previous TP4 release this was less than half.
I have windows XP with Firefox, OracleXE, jdeveloper/weblogic and the memory footprint is at 2G. We already had to upgrade our systems, do we need to upgrade yet again???

It seems that the commandline for starting the embedded weblogic has two instances of the -Xmx and Xms parameters. I think the last one is the one that is used, and it is set to 1024M, which is large for a large portion of development projects.
The parameters are present in setDomainEnv.sh/cmd. It is situated in <JDEV_HOME?>system11.1.1.0.31.51.56/DefaultDomain/bin
I've seen this directory show up in funny places so search for it if you can't find it.
I've set the second set of parameters to the same as the first ones -Xms256m -Xmx512m.

I'm on iTunes 11.0.0.63 for Windows. iTunes used to display the total number of songs in my library, along with total playtime and memory footprint, at the bottom of the window. How can I make it display this information like it used to?

Hello! Thanks in advance for reading my question.
so, I updated iTunes to 11.0.0.63 on Windows, and the new layout looks nice, but iTunes no longer gives my total song count, memory footprint, and total play-time at the bottom of the window, the way it used to. I just want to know how to get that info back. Thanks so much!

Ctrl / or View > Show Status Bar should do it.
Weirdly having turned mine on the menu is not there to hide it again and the shortcut doesn't work.

Low Memory Footprint JVM needed, Please suggest.

Hi guys,
I want a light weight (low memory footprint) Java Virtual Machine compatible with Java 1.5. It should be open source. Can anybody suggest me please. I've googled and tried to use some JVMs like Kaffe and SableVM. But I want some reliable VM.
Thanks,
Dhaval.

Query is allocating too large memory

I’m building an Analysis in OBIEE against an ASO cube and am seeing the following error:
Query is allocating too large memory ( > 4GB) and cannot be executed. Query allocation exceeds allocation limits
The report we’re trying to build is intended to show information from eight dimensions. However, when I try to add just a few of the dimensions we get the “Query is allocating too large memory” error. Even if I filter down the information so that I only have 1 or 2 rows in the Analysis I get the error. It seems like there is something wrong that is causing our queries to become so bloated. We're using OBIEE 11.1.1.6.0.
Any help would be appreciated.

Any help would be appreciated.Hi,
This sounds like a known Bug 13331507 : RFA - DEBUGGING 'QUERY IS ALLOCATING TOO LARGE MEMORY ( > 4GB)' FROM ESSBASE.
Cause:
A filter has been added in several lines in the 'Data Filters' Tab of the 'Users Permissions' Screen in the Administration Tool (click on Manage and then Identity menu items). This caused the MDX Filter statement to be added several times to the MDX issues to the underlying Database, which in turn caused too much memory to be used in processing the request.

One immediate thing: "EA6" is in the tag library namespaces, but you're using EA12.
In general, there've been a lot of changes between EA6 and EA12, but the changed namespace is one simple thing.

ADF-UIX- How to populate multiple input fields from an lov?

Like in Forms Developer where using an LOV we can populate multiple tex input items on selection of a value from the LOV, is it possible for us to do the same in ADF UIX.
Iam usiing JDeveloper 10.1.2

Have a look at this previous post:
Re: Can return messageLovinput more than one value?

Display CLOB value in multiple rows in ADF UIX

Hi,
I have an ADF UIX application that uses data that are stored in a CLOB column in an Oracle Database.
The table data is presented in a simple table in page1.uix, I use BC4J for accessing the Database and Oracle JDeveloper 9.0.5.2.
The problem is that the CLOB data appear properly (meaning the rows appear OK) only in a frame (messageTextInput element) of a predefined size and if I change the element into a styledText or a formattedText the frame will not appear, but all the CLOB characters appear in a single row.
Does anyone know how I can present the CLOB text data in a UIX page, without having a frame around the text, and at the same time keep the CLOB text in multiple rows?

There's no completely trivial way. You'd have to do a bit of extra processing of your CLOB data. The most straightforward work to do is to convert "\n" into "<br>", and then pass that into a <formattedText>.

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.
http://www.oracle.com/technology/products/jdev/collateral/tutorials/9050/adfuix_tut.html
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 ...
Cheers
Ian

ADF UIX: Get value in LOV messageList.

I have a messageList that bind to a vo but when I call getTxtCodeCat method from the Struts form bean in Action Class, it does always return me a list index (0,1,2...).
<struts:messageList model="${data.protecteddoc_GN_GnCodeSetupUIModel.CodeDescription}" name="txtCodeCat" prompt="[Code Category]" styleClass="DropdownMedium" required="yes" size="1">
<contents childData="${data.protecteddoc_GN_GnCodeSetupUIModel.CodeDescription.displayData}">
<option model="${uix.current}"/>
</contents>
</struts:messageList>
Please advice how do I retrieve the value instead of index from the LOV?

This thread is a duplicate. Direct all followups to:
Urgent! ADF UIX:LOV messageList returned index no. during runtime.

File upload, download using ADF UIX and not JSP

I have examples for the file upload, download using JSP
But I want to use ADF UIX. Look and feel in this is impressing and I want to use this. Any one have example for this.
Users will select a file from their desktop
This will be stored into the database (Any document. Word, Excel)
When they query the records then the UIX column need to give a hyperlink. Clicking on the link should prompt to download the file to the local system

Sure, I use the Apache Commons File Upload package, so that is what I will discuss here ( [Commons File Upload|http://commons.apache.org/fileupload/] ).
The Commons File Upload uses instances of ProgressListener to receive upload progress status. So first create a simple class that implements ProgressListener:
public class ProgressListenerImpl implements ProgressListener {
    private int percent = 0;
    public int getPercentComplete() {
        return percent;
    public void update(long pBytesRead, long pContentLength, int pItems) {
        if (pContentLength > -1) { //content length is known;
            percent = (new Long((pBytesRead / pContentLength) * 100)).intValue();
}So in your Servlet that handles file upload you will need to create an instance of this ProgressListenerImpl, register it as a listener and store it in the session:
ServletFileUpload upload = new ServletFileUpload();
ProgressListenerImpl listener = new ProgressListenerImpl();
upload.setProgressListener(listener);
request.getSession().setAttribute("ProgressListener", listener);
...Now create another servlet that will retrieve the ProgressListenerImpl, get the percent complete and write it back (how you actually write it back is up to you, could be text, an XML file, a JSON object, up to you):
ProgressListenerImpl listener = (ProgressListenerImpl) request.getSession().getAttribute("ProgressListener");
response.getWriter().println("" + listener.getPercentComplete());
...Then your XMLHttpRequest object will call this second servlet and read the string returned as the percent complete.
