Is heap memory is particular for a workprocess?and extended memory too?

Is heap memory is particular for a workprocess?and extended memory too?
All the while I need to know is :is more than one workprocess can be in Priv mode?

Yes - heap is workprocess exclusive memory.
Extended memory is shared on the instance.
Yes - more than one WP can go to PRIV mode.

Changing heap memory paramter and Additonal Java node configuration

Hi All,
Kindly provide me the procedure to change the heap memory parameter and location (in Visual admin). How to install/configure 2nd Java server node in PI system.
Thanks in advance.

Hi Ramesh,
You would have posted this question in Netweaver Administrator forum...
Well here are the answers.
Login to Configtool.
Expand Cluster-Data->instance<xx>->dispatcher. On the right hand side you can change the heap size for the dispatcher
Follow the same procedure to increase the server heap memory.
To add the server node click on instance<xx>. Then click Server->Add server.
Cheers....

Confusion on Java heap memory and WLS_FORMS

Hello all,
Background first:
Oracle Forms/Reports 11.1.2 64-bit
WebLogic Server 10.3.6
JDK 1.6 update 37 64-bit
Microsoft Windows 2008 R2
Using nodemanager to start/stop managed servers
After having read all of the documentation and searched both this forum and the Internet for advice, I'm still utterly confused about the best way to make use of memory on the server (the server I'm working on now has 8GB). The two trains of thought that I have discovered in my search:
1). Don't change the Javaheap size at all (stick with the defaults) and just create additional managed servers on the same machine.
2). Increase the Java heap size for WLS_FORMS
Having said that, here are my questions:
A). What is the best-practices approach (#1 or #2)?
B). If it's #2, what's the approved way to increase the heap size? I have tried adding -Xms and -Xmx arguments to the WLS server start arguments in the WLS console. These are applied when the managed server is started (confirmed in the log file), but because of the way WLS_FORMS is started, there are more -Xms and -Xmx arguments applied after mine, and Java picks the last one mentioned if there are duplicates.
First update: Question #2 seems to be answered by support note 1260074.1 (the one place I hadn't yet looked)
Thanks for any insight you can provide. If there's a document I've missed somewhere, I'm happy to be told where it is and will read and summarize findings here.
Regards,
John

John,
Let me try to comment on each of yours:
1). We had been getting some "Apache unable to contact the forms server" type errors (the users were seeing the "Failure of server APACHE bridge" error). The log files showed nothing of interest. I increased the memory allocated using setDomainEnv.cmd, and the error seems to have gone away. Yes, I know that it was a shotgun approach, trying something without really having a reason to do so, but it seems to have helped Edit: Now that I review the OHS logs instead of the WLS_FORMS logs, I have found log messages, which leads me to Doc 1380762.1, which tells me I need a patch. DOH. And, oh crikey, Forms 11.1.2.1 is out, it came out shortly after we downloaded 11.1.2.0 to create these environments. Good news/bad news kind of thing... <blockquote>The Apache Bridge error is fairly straight forward if you understand what it is telling you. It is an error generated by mod_wl_ohs who is owned by OHS (Apache). This module is responsible for the connection between OHS and WLS. The Apache Bridge error means that OHS (mod_wls) was unable to get a response from the WLS managed server it was calling. Basically it was unable to cross the bridge ;) The cause could be anything from the managed server is not running, to the managed server is over tasked, or there is a network configuration issue and the managed server simply didn't hear OHS calling.
This is all discussed in MOS note 1304095.1
As for 11.1.2.1, this can be installed fresh or as a patch over 11.1.2.0. So for machines that don't currently have anything installed, you can go directly to 11.1.2.1 without having to install 11.1.2.0 first.</blockquote>
2). As tony.g suggested, we are looking for what we should do to solve the "I have n servers with x GB of RAM, what should I do to the out-of-the-box configuration of Forms for stability" question. <blockquote>As I mentioned, there really are no "Forms" specific tweaks related to how much RAM your machine has. The only exception to this is (although somewhat indirect) to use JVM Pooling. JVM Pooling can reduce the size of each runtime process's memory footprint by moving its java calls to the jvm pool then sharing common requests with other running runtimes. Memory usage by OHS or the WLS managed server really has little to do directly with Forms. Specifically to the managed server, from a Forms point of view, I would not expect the memory cost of WLS_FORMS to increase much because of load. I expect it to increase as concurrent load increases, but I would not expect it to be significant. If I had to guess, seeing an increase of 1m or less per user would not surprise me (this is just a guess - I don't know what the expected values would be). If we were to use our (Oracle) older scalability guidelines, typically we would have suggested that you should consider about 100 sessions per 1 jvm for best performance. Given that v11 uses a newer java version and scalability is better today, I suspect you can easily scale to a few hundred (e.g. 300) or so before performance drops off. Beyond that, the need to add more managed servers would likely be necessary.
This is discussed in MOS note 989118.1</blockquote>
3). HA is important to us, so we are implementing a cluster of Forms/Reports servers with an LBR in front of it. I have read in the docs on clustering, cloning a managed server, and via Support, how to increase the heap memory for the WLS_FORMS server. My thought process was "if Oracle gives me instructions on how to increase heap memory and how to clone managed servers, there must be a scenario in which doing so provides benefit." I'm trying to understand the scenarios in which we would do either of those activities. <blockquote>Refer to the note I mentioned above. Generally, if you limit the number of concurrent sessions to less than around 300-400, I would think the default settings should be fine. If you think you would like to go beyond 300 or 400 per managed server then likely you will need to increase the max heap for the managed server. Again, refer to the note I mentioned previously.
Also see MOS note 1260074.1</blockquote>
I am aware of the JVM pooling (yes we do call out to Reports) - I've yet to implement this, but it's on my to-do list.
<blockquote>This is discussed in the [url http://docs.oracle.com/cd/E38115_01/doc.111210/e24477/jvm.htm]Forms Deployment Guide</blockquote>
Hope that helps ;)

Local roll area and Roll area

Please refer to following contents from TADM12_2:
1. Virtual Memory includes local memory and shared memory.
2. Local memory is associated with individual work processes.
3. Local work processes memory is for: ABAP load; Data, stack; Buffer for database transfer; Local roll area; Local paging area.
4. The roll file and its associated buffer(also called Roll area).
5. The page file and its associated buffer(also called (SAP) Paging area).
In t-code ST02,
1. the first part is Buffer, all of them belong to shared memory.
2. the second part is SAP Memory, there are four sub-items:
    a)Roll area
    b)Page area
    c)Extended memory --> in shared memory
    d)Heap memory --> in local memory
I am confused whether Roll Area and Page Area here means local Roll/Paging Area in local memory, or Roll/Paging Buffer in shared memory?
Please advise. Thanks
James

Hi James,
Roll Area and page area allocated on local memory, and their buffer areas are allocated on local memory, also. This is because roll and page area are first two block on memory diagram. Those memory areas are dedicated to a work process and start to use when extented memory is filled up. Take a look at "http://help.sap.com/saphelp_nw70/helpdata/EN/28/d1d3f6bcb411d188b30000e83539c3/frameset.htm" for the memory diagram on SAP

Threaded inner classes & heap memory exhaustion

(_) how can i maximize my threading without running out of
heap memory?
push it to the limit, but throttle back before an
java.lang.OutOfMemoryError.
(_) within 1 threaded class ThreadClass, i have two threaded inner classes. for each instance of ThreadClass i only
start one instance of each inner class.
and, i start hundreds of ThreadClass, but not until the previously running ThreadClass object exits, so only one should be running at any given time.
so, what about threaded inner classes?
are they good? bad? cause "OutOfMemoryErrors"?
are those inner threads not dying?
what are common causes of:
java.lang.OutOfMemoryError: java heap space?
my program runs for about 5-minutes, then
bails with the memory error.
how can i drill down and see what
is eating-up all my memory?
thanks.

A Thread class is not the same as a thread of
execution. Those inner class based threads of
execution are not dying.maybe. but this is the way i test a thread's life:
public void run() {
System.out.println("thread start");
System.out.println("thread dies and release memory");
}for each inner thread, and the outer thread, this approach for
testing thread life reveals that they die.
Why don't you use a thread pool?ok. i will think about how to do this.
>
If not, you need to ensure those inner threads have
exited and completed.what is a 100% sure check to guarantee a thread exits other than
the one i use above?
note:
the outer thread is running on a remote host, and the inner threads
are running locally. here are the details:
public class BB implements Runnable, FinInterface {
public void run() {
    // do some work on the remote machine
private void startResultsHandler(OisXoos oisX) {
     ResultHandler rh = new ResultHandler(oisX);
     rh.start();
public void startDataProxy(OisXoos oisX, String query) {
     DataProxy dp = new DataProxy(oisX, query);
     dp.start();
        public class ResultsHandler extends Thread {
           // runs locally; waits for results from servers
           public void run() {
               ObjectInputStream ois = new ObjectInputStream(oisX.input);
                Set result = (Set) ois.readObject();
        } // ____ class :: _ ResultsHandler _ :: class ____
       public class DataProxy extends Thread {
           // runs locally; performs db queries on behalf of servers
           public void run() {
               ObjectOutputStream oos = new ObjectOutputStream(oisX.output);
                while(moreData) {
                    .... // sql queries
                    oos.writeObject(data);
             StartResultsHandler(oisX);
        } // _____ class :: _ DataProxy _ :: class _____
}now, the BB class is not started locally.
the inner threads are started locally to both service data requests
by the BB thread as well as wait for its results.
(_) so, maybe the inner threads cannot exit (but they sure look
like they exit) until their parent BB thread exits.
(_) yet, those inner threads have no knowledge that the BB

externalizing those inner thread classes will put 2-weeks of work

here this piece of code that controls everything:

Find heap memory Size for Web Intelligence processing server in BO 4.0

Hi All ,
We need to gather data for sizing inputs.For Adaptive processing server , we can find same by going in CMC> Server > APS > Properties & check value for the parameter -Xmx . Could you please tell how to find the max heap memory allocated for a Web Intelligence processing server in BO 4.0 as for Webi server this parameter is not maintained. ?
Regards ,
Abhinav

Hi Abhinav,
The maximum threshold is a value which may reach on peak usage and Webi processing server cannot occupy memory beyond this value at any time.
In your situation 9 Webi Processing servers with 16 GB of RAM on server is not recommended. This is because consider situation with total 16 GB of host RAM.
4 GB should left for OS
Tomcat will need minimum 2 GB for 200 users
So you are left with 10 GB RAM for all BO services
Now 9 Webi Processing servers with 6 GB of Threshhost will not work here
For this configuration you can have 2 Webi Processing servers with default threshold should be running on single host.

Hrishikesh

Can I increase heap memory without specify any class or jar file??

Hi,
I tried to increase my heap memory in this way :
java -Xms256m -Xmx256m
but I got an error ... it's seem that I must specify a class java or a .jar file ...
This is the error :
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]

where options include:
-client to select the "client" VM
-server to select the "server" VM
-hotspot is a synonym for the "client" VM [deprecated]
The default VM is client.

What is it supposed to do with your request to use 256m of memory for heap
when you are not giving it a class or a jar to run?

Difference between nio-file-manager and nio-memory-manager

Hi,
what's the difference between nio-file-manager and nio-memory-manager? The documentation doesn't really discuss the differences as far as I know. They both use nio to store memory-mapped files don't they? What are the advantages/disadvantages of both?
When to choose the first one and when the second when storing a large amount of data? Can both be used to query data with the Filter API? Are there size limits on both?
Best regards
Jan

Hi Jan,
The difference is that one uses a memory mapped file and one uses direct nio memory (as part of the memory allocated by the JVM process) to store the data. Both allow storing cache data off heap making it possible to store more data with a single cache node (JVM) without long GC pauses.
If you are using a 32 bit JVM, the JVM process will be limited to a total of ~3GB on Windows and 4GB on Linux/Solaris. This includes heap and off heap memory allocation.
Regarding the size limitations for the nio-file manager Please see the following doc for more information.
With the release of 3.5 there is now the idea of a Partitioned backing map which helps create larger (up to 8GB of capacity) for nio storage. Please refer to the following doc.
Both can be used to query data but it should be noted that the indexes will be stored in heap.
hth,
-Dave

Roll in and roll out

hai
      what is rollin and rollout ?
      what is saint update?

Hi,
When users request for connection to the sap server, all the requests are put in a queue by the dispatcher. When the dispatcher finds a free workprocess, the user request is assigned to that work process on FIFO basis. Data input provided by the user are transfered to the memory area of the workprocess. The work process communicates with the database as per the requirement of the user querry and picks data from the database into its memory area and inturn returns it to the user.
    When the user terminates the connection the work process attached to it flushes its memory area and becomes free again to be assigned to another user request. This flow of data into the memory of the workprocess and flushing of data from the memory of the work process is known as roll-in and roll-out.We can say the rollin takes place at the begining of a user request and rollout takes place on termination of the same.
SAINT update:
saint update means applying a patch to enhance the functions of saint. This becomes necessary to accomodate the newer attributes of the new add-on support packages. Saint is mainly used for add-on tools.
Hope this clarifies your querry.
Pls dont forget to award points if solved.

So I think that if can off JVM heap Memory used in the Near-Cache front-tier?
Or can help how to config the off JVM heap Memory used in the Near-Cache front-tier.
Thanks.

Only local-scheme and class-scheme can be used in the front-scheme of a near cache.

UCCX 7 Heap Memory Usage Exceeded Error

UCCX 7.0.(1) SR5
Getting the following error when updating or adding new script applications:
"It is not recommended to update the application as Engine heap memory usage exceeded configured threshold. Click OK to continue and Cancel to exit."
Apparently this is an alert that was built into SR4 and is configurable under the System Parameters.
Does anyone have information on what processes use the heap memory in UCCX or how to monitor the usage?

As Tom can attest to by now, this is something of an iceberg with big sharp edges below the surface.
The Java heap is fixed at 256MB on CCX. The Java heap is used by Tomcat as execution memory. In addition to this, applications, scripts, and other repository data is loaded into the heap at runtime. Depending on your environment, you may be approaching the limits of the heap, which cannot be changed. If the heap size is reached, it will be dumped and impact calls.
What have you been doing as of late on your CCX server? How many applications and scripts do you have? Are any of these using XML files extensively?
Note there is also a possible bug where the MIVR engine does not properly release all objects loaded into the heap at the end of a script execution leading to a memory leak of sorts. The discussion [debate] over this behavior is continuing. As of this week, it may be represented under

OAS Heap memory issue: An error "java.lang.OutOfMemoryError: GC overhead

OAS - 10.1.3.4.0
We are running out of Heap memory and seeing lots of full GC and out of memory events
Verbose GC is on.
Users don't know what they are doing to cause this
We have 30-40 users per server and 1.5 GB heap memory allocated
There are no other applications on the machine. Only the PRD instance with 1.5 GB allocated to the JVM. We do not have any issue with memory on the server and we could increase the heap but we dont want to go over the 1.5 GB since that is what I understood to be the high end of what is recommended. we only have 30-40 users on each machine. There are 8 servers and a typical heavy usage day we may have 1 or two machines that have the out of memory or continuous full GC in the logs. When this occurs the phones light up with the people on that machine experiencing slowness.
below is an example of what we see in a file created in the OPMN log folder on the JAS server then this occurs. I think this is the log created when Verbose GC is turned on. I can send you the full log or anything else you need. Thanks
