Heap size and 3 table update

I am new to this area so sorry if my questions will sound stupid to somebody. Recently I started developing an application using Toplink, ADF Databinding, struts and JSP. Curretnly the application is using 1 view built on 3 tables.
QUESTION 1: First time when I tried to test the browse page I got the error messages from JDeveloper saying "JBO-29000: Unexpected exception caught: java.lang.OutOfMemoryError, msg=null". So I limited number of records selected by the view just to 500 and the query worked. I guess it is somehow related to java heap size. How can I change the heap size. The application is run locally on my PC.
QUESTION 2: In this application I am trying to update 3 tables at the same time using a view. But when I try do it I am getting error saying "data manipulation operation non legal on this view error code 1732". Is there any way I can do this simultaneous update of 3 tables through the view?
Thanks in advance for any help, advice or hint

Help regarding 'table controls' and 'internal table' updation

Hi all.
Basically this is what i have done..... I have created a table control in module pool program. I declared an Internal table and also have populated it from a database table. I have also used insert statement to insert an blank record in the table control view and delete statements to delete any record, also in the table control view... .
But I am not able to update any new record into an Internal table or the original table ..
Any Ideas how to do it ,Gurus
Thanks

RBKP and BKPF table update from MIRO

Hi All,
I am using the BADI BADI_FDCB_SUBBAS01 to add a custom field in MIRO transaction. The added custom field is getting updated in RBKP transaction.
I also want to update the custom field data in BKPF table, but i dont know when the BKPF table gets updated in MIRO transaction.
Can you help me where the BKPF table will get updated. Is there any BADI for updating the custom fields in table BKPF via MIRO?
Thanks and Regards,
Vijay

Hi Baskar,
I have done this thing from MIRO transaction to update BKPF table. Please check the below code.
METHOD if_ex_badi_fdcb_subbas01~put_data_to_screen_object.
CONSTANTS:
c_bkpf_xref1(25) TYPE c VALUE '(SAPLFDCB)BKPF-XREF1_HD'.
FIELD-SYMBOLS: <fs_bkpf_xref1> TYPE ANY.
fill interface attributes from importing paramters
me->if_ex_badi_fdcb_subbas01~invfo = im_invfo.
ASSIGN (c_bkpf_xref1) TO <fs_bkpf_xref1>.
IF sy-subrc = 0.
    <fs_bkpf_xref1> = me->if_ex_badi_fdcb_subbas01~invfo-zlet_number.
ENDIF.
ENDMETHOD.

JVM heap size and performance

We are kind of struggling with the good old "out of memory"
issue of JVM while running our app on oracle 9i j2ee container
(Solaris 2.6). I do not see much discussion about this
particular problem in this forum. We are playing with heap
allocation, garbage collector, max num of instances etc to
overcome this out of memory issue. If you are running or about
to run OC4J in a production environment please let me now what
measures and settings are you using to tune the JVM.

We start with 128m, and use 512m for the maximum, and have no
troubles. That is:
java -jar -Xms128m -Xmx512m orion.jar
This is on linux. There are memory leaks with varous jdbc
drivers, postgresql for example.
Also, if you do not put a maximum on your instances of entity
beans, they will just pile up. You can adjust this in the orion-
ejb-jar.xml file. The bean problem occurs if you have not
normalized your bean mapping for performance.

Java options heap size and out of memory warnings

I have a 904 10g oc4j mid-tier build.
I have three applications deployed to the Home container.
Occassionally, one of the applications will get an error message stating java.lang outofmemory. The java Option was set to Xmx1024. I increased this to Xmx2048, but this had an adverse affect on the Home container and I couldn't get it running. Eventually I put the value for java option back to it's original value. The Home container started again.
Is there another way I can increase the amount of memory available to the container/applications without having the adverse effect described above?
Thanks
Andy

how much is your available physical memory size ?
if you have more than 1 Gb, follow this :
try set jvm options :
-Xms1024m -Xmx1024m -XX:MaxPermSize=256m
try to increase MaxPermSize if error still occured.

How to increase Memory and Java Heap Size for Content Server

Hi,
My content server is processing requests very slowly. Over performance is not good. I have 2 GB of RAM any idea what files I can modify to increase the Java Heap Size for the Content Server. If I increase the RAM to 4 or 6 GB where do I need to make changes for the Java Heap Size and what are the recommended values. I just have Content Server Running on the linux box. Or how do I assign more memory to the user that owns the content server install.
Thanks

NT Service and Heap size

Can someone tell me if there is a way to :
(1) verify and modify heap size in nt service?
(2) in multi server mode, there are two nt services for weblogic
domains, is it needed to change heap size for weblogicAdmin service for
heap size increase? What will happen if PIA is 1024MB heap size and
weblogicAdmin is 256MB?
Thanks in advance/T

Nicolas, test show that once the nt service is installed, modifying heap
size in setenv.cmd and run setenv.cmd file reinstall nt service does not
change the heap size already in registry. So, test shows that I can
modify the heap size directly in registry and restart service?. Am i doing something wrong here.. can i correct and only to modify and existing heap size in
registry?
Please let me know what else should I do once the old heap
size in already in registry and not the new heap size when reinstalled NT service.
other question, long the weblogic tuning, I found the following from bea site. During the peak time, we may have 40000 unique users per day. Should I also consider increase maxUserPort? The weblogic domains are hosted on windows 2003 servers.
Windows Tuning Parameters
For Windows platforms, the default settings are usually sufficient. However, under sufficiently heavy loads it may be necessary to adjust the MaxUserPort and TcpTimedWaitDelay. These parameters determine the availability of user ports requested by an application.
By default, ephemeral (that is, short-lived) ports are allocated between the values of 1024 and 5000 inclusive using the MaxUserPort parameter. The TcpTimedWaitDelay parameter, which controls the amount of time the OS waits to reclaim a port after an application closes a TCP connection, has a default value of 4 minutes. During a heavy loads, these limits may be exceeded resulting in an address in use: connect exception. If you experience address in use: connect exceptions try setting the MaxUserPort and TcpTimedWaitDelay registry values under the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters key:
MaxUserPort = dword:00004e20 (20,000 decimal)
TcpTimedWaitDelay = dword:0000001e (30 decimal)
Increase the value of the MaxUserPort parameter if the exception persists.
For more information about Windows 2000 tuning options, see:
§ The Microsoft Windows 2000 TCP/IP Implementation Details.
§ The Windows 2000 Performance Tuning white paper.

How to increase the heap size of the container in whioch BPEL is running ?

Hi All,
I recently raised an SR they have asked me to do the following,
Can you please try and start the container running the BPEL process with max
heap space (-Xmx) of 2 GB and the eden space (-Xmn) at about 60% of 1228m and
the option -XX:+AggressiveHeap set. (even though this option is recommended for
multi processor machines say 4)
can anyone kindly explain me how to increase the Heap size and Eden size of BPEL container ?
Thank You

Hi Deepak I cant see any attribute or element in the oc4j_opmn.xml file regarding heap memory. In the server properties I changed the size of heap memeory how can I rollback.

How do define the limit of the max heap size?

Hi All,
I would like to know what should be the limit of the JVM max heap size.
What will happen if we will not define it?
What is the purpose of defining it from the technical point of view?
Thanks
Edited by: Anna78 on Jul 31, 2008 12:36 PM

Defining a max heap space too large can have the following effect:
If you create new objects, the VM may decide it is not worth getting rid of garbage-collectable ones, as there
is still plenty of space between the current heap size and the max allowed. The result will be that the
application will run faster and will consume more memory than it really needs.
If the heap size is too small, but still sufficient, the application will do a lot of garbage-collection and therefore
run slower. On the other hand, it will stay inside the tight space it has been allowed to use.
The speed difference may or may not be noticeable, while the difference between 256M and 512M may
or may not matter on today's computers.

Overriding the default heap size of 64mb

I run the java program on my pc on windows xp
I need to increase the heap size, currently I launch the jar file using a batch file, the contents of the batch file are:
java -Xms64m -Xmx512m -jar Lines.jar
I have set the min and max heap size and when I click on the .bat file it launches the jar file with tose heap settings
But I do not want to launch the jar file in this way(I don't want to use a batch file), is there anyway to override the default heap size for the java program to 512mb so that every time I launch the jar file the heap size is 512mb??

Why JVM shows another Heap size when Xms=Xsx?

Hi everybody. I have two instances of oc4j on a cluster of two nodes. The configuration of parameters on opmn.xml is exactly the same for both instances.
Particulary I see an strange behavior on memory heap. I expect that if Xmx and Xms parameters are equals to 4096, then the heap size must be fixed on 4 Gb exactly, and there will be not resizing.
But monitoring the heaps with JVisualVM I can see that the heap size of the first instance is moving between 3.7 and 4 Gb, and the Heap size of the second node is moving around 3.2 Gb. The hosts have both 16 Gb of RAM, it's running on Windows 2003 Server R2 and there is no overload on the OS.
Possibly the behavior is normal and I just have a wrong understanding of what is expectable.

Hi Sebastien, Thanks for responding.
In fact I'm looking exactly where you say to determine your heap size.
The thing is that I can't understand why one instance takes some minor heap size and fluctuates the size while the other instance take around 4 Gb and kept static in this value. I can see there is no diferences on configuration for both. I know that the used heap must present diferent behavior, but not the total size. I think that the size should be fixed and static with Xmx=Xms=4096, but this is not happening.
I would like to show an image to ilustrate what I'm describing.
About the PermGen, I think there's no problem with that, around 80% is in effective use, and this value is stable.
Best regards

How to change heap size in control panel

i've already searches previous post about this problem but still i couldnt get it to work or maybe i'm doing it wrong. i did it a lot of times but still i couldnt get it. can anybody show me how exactly to change the java heap sizes.
and is it possible to display the current java heap size of my jvm?
tnx in advance
nashstanley

You can change the heap by using an option to to the java command, when Java starts up. If you're starting an applet or a Web Start app(applies only to applets or Web Start) then use the Java Control Panel's Java tab to set a value.
The syntax (in all cases) is defined in the documetation for the java command.
There are a number of ways to see the heap size, none of which is "standard" Java, and they vary depending on the specifics of which Java you're running and what you're doing. See:
http://www.google.com/search?q=display+java+heap+size

Retrieve Heap size from program

Hi, i searched the foruns with "get heap size" and "retrieve size"
and i also checked the System.getProperty(String key) string keys at
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/System.html#getProperty(java.lang.String)
and havent found a method to retrieve the currently set heap size.
Is there a way to do this?
My program needs to initialize something based on how large the
user set the heap size (using the command line -Xms32m -Xmx128m...)
Any info would be appreciated! Thanks alot!

Change table size and headers in type def cluster

Is is possible to change a table size and headers that is inside a type def cluster?
I have a vi that loads test parameters from a csv file. The original program used an AC load so there was a column for power factor. I now have to convert this same program to be used with a DC load, so there is no power factor column.
I have modified to vi to adjust the "test table" dynamically based on the input file. But the "test table" in the cluster does not update it's size or column headers.
The "test table" in the cluster is used through out the main program to set the values for each test step and display the current step by highlighting the row.

Nevermind, I figured it out...
I was doing it wrong from the start, in an effort to save time writing the original program I simply copied the "test table" to by type def cluster. This worked but was not really as universal as I thought it would be, as the table was now engraved in stone since the cluster is a type def.
I should not have done that, but rather used an array in the cluster and only used the table in the top level VI where it's displayed on the screen.
