How to test the memory..?

Hi friends.. Iam created java application Multithreaded socket server... I need to check the size of the memory of before and after execution of the program..... Is there any tool for memory debugging......?thanks in advance.....

You can check continuously during operation using JVMStat from Sun. It's a beautiful tool that will show you the entire memory model: eden and perm spaces, etc. Very nice UI.

How to define the memory leak in stability test

Hi
Usually, we run our system with 70% CPU load for 72 hours for stability test (on solaris 10), because some plugin of our system is using mtmalloc, and we use prstat to monitor the memory of each plugin. But because of the complex memory usage of our application, we don't know when the application will use the Max memory, and because of the "mtmalloc", the memory showed by "prstat" will not released but continually increased.
So fro the test point of view, there is the risk of memory leak, but actually, there may be no memory leak, so my question is how to define the memory leak in such condition.

Thank you for the input and all the info.
isn't java heap the same as memory allocated to the java process in my weblogic
starup script ?The heap is sized by the -Xmx and -Xms parameters you pass on the java
command-line. The permanent generation is separate.

let me also download jprobe and try to run it and see what it gives me.
I'd start by running with -verbose:gc. I'd want to know whether you're
running out of heap or permgen space.

Unfortunately memory leaks are not fun to track down even with tools.
I'd first suggest determining whether you're running out of space in
the
permanent area (where classes are loaded), or you've exhausted the java
help space.
I'd start by adding -verbose:gc. Look at the gc messages right before
you hit the OutOfMemoryError. If there's plenty of space left, I'd
suspect you're running out of perm space. Search these newsgroups and
the web for MaxPermSize, and you should see plenty of info.
If you're running out of java heap, tools like jprobe and OptimizeIt
are
helpful. If you can tell me a little more about your application and
how you're testing it, I can offer some more tips.

How to overcome the Memory leakage issue in crystal report 2008 SP2 setup.

I have developed the small windows based application tool with help of Visual studio 2008 for identify the memory consumption of crystal report object. It helps to load the crystal report objects in the memory and then released the object from the memory. The tool simply does the u201CLoading and Unloadingu201D the objects in the memory.
The tool will be started once u201CTest_MemoryConsumption.Exeu201D executed. The u201CTest_MemoryConsumption.Exeu201D consumes u201C9768 KBu201D memory before load the crystal report object in memory. It means, 9768 KB is normal memory consumption for run the tool.
Crystal report object initiated by the tool and object help to load the report in memory once the tool initiated the crystal report object. Now u201CTest_MemoryConsumption.Exeu201D consumes u201C34980 KBu201D memory during the crystal report object creation and report load process. The actual memory consumption of crystal report object is 34980u20139768=u201C25212u201DKBu201D.
The memory consumption u201C34980 KBu201D will be continued till the end of the process. The memory consumption will be reduced to u201C34652 KBu201D from u201C34980 KBu201D once report load process completed. It means, u201C328 KBu201D memory only released from the memory consumption. Tool enables the Release command for the crystal report object. But crystal report object does not respond to the command and will not release his memory consumption.
The memory consumption u201C34652 KBu201D will be stayed in the memory once job ends. If i again initiate the crystal report object then it crystal report object start to consume the memory from 34652 KB.
Database objects and crystal report objects are properly used in the tool. The object release commands properly communicated to crystal report setup. But the u201CCrystal report service pack 2u201D setup unable to respond the commands which has enabled from .Net Tool. Crystal report objects are properly initiated and disposed in the tool. But the crystal report unable to release from the server.
The memory consumption will be reduced once the server restarted or kill the application.
Crystal report 2008 and crystal report 2008 SP2 setup available in the server.
Microsoft .Net Framework 2.0 SP2, Microsoft .Net Framework 3.0 SP2 and Microsoft .Net Framework 3.5 SP1 are available in the server,
Could you please suggesst how to avoid the memory consumption keep increasing and how to release the memory consumption once the crystal object disposed???

Hi Don..
My case is different one. I hope, the problem with Run time Installation setup file (Crystal report 2008 Serivce Pack2 installer) which we installed in the server.
Let me explain with Live scenario which our client faced in crystal report 2008 Service pack2 Installer.
Our client is using a application to help to print their reports. The application is developed with Windows service.
Windows service keep on running in the server. Windows service executes the client 's crystal reports( Labels Report, Stock report) which designed for clients need and the reports will be printed from printer.
10 Same type report (Label Report) will be printed in 1 minute. Reports are not printing during non business hours. But the windows service keep on running. Memory cosumption of application will be 160 MB in business hours.
For Example, On Monday the application memory consumption starts with 160 MB. The Memory consumption will be reached 165 MB in peak business hours. Then the memory will be ended in163 MB in the End of Monday. It means, The memory consumption will be in 163 MB during the non business hours. Reports will not be printed in non business hours.
On Tuesday, the application memory consumption starts with 163 MB and it will be reached 168 MB during the peak hours. The Memory consumption will be ended in 165 MB in the end of Tuesday. The same process contiues till friday. End of friday, the memory consumption of the application will be ended with 170 MB.
Application Memory Consumption slowly increasing in the server. In 5 days, Memory consumption reached Threshold value (170 MB) of the server. Application gets hanged up once the memory consumption reached 170 MB. We got the error messages as "Attempted to read write protected memory " / "Not Enough memory for process". If we restart server / If we restart the service then memory consumption of application get reduced to 160 MB.
From the above scenario, We came know that the either the problem with Application object or the problem crystal report object. In the application, We have checked dispose methods of application objects completly. I am sure that application objects are properly disposed in the application. I hope the problem not with application objects. The problem with Crystal report objects.
Application properly communicates the dispose methods to crystal report objects. Crystal report objects are not released from
the memory.
Crystal report 2008 Serive Pack 2 setup installed in the server.
As you said, If Crystal report runtime is not released from memory then memory consumption keep increase??? In service oriented architecture application, how to unload the crystal report runtime??
Do you any fix for this kind of issue??
Willl Crystal report 2008 service pack 3 help on this issue??

How to test the payload in XI

Hi all,
could please explain how to test the payload in xi and with steps.
Thanks in advance,
Radhika

Hi Radhika,
You can test in three ways.
1.) In message mapping directly give the relevant data and then execute. Here you can test whether the mapping is correct or not.
2.) In Integrstion Directory after completing and activating the Configuration, in tool you can find the Test Configuration tab. There you can give the sender and receiver details along with payload. Here you can test whether the Configuration is correct or not.
3.) In RWB in COmponent monitoring. Select the Integration Engine Monitoring. Here give the sender and receiver details, Interface name, name space, Quality of service.
Now give user name and pass word.
Paste the payload from massage mapping and then press test tab. Here yoyu can directly send the message from XI server to the receiver system.
Ok,

How to test the rule if multiline container is passing to the task?

Hi Experts,
                  I am working on leave workflow. I have to get the approvers based on no of days of leave and leave type. I am getting these details in ITEMS_TAB internal table. I am passing this table to a rule. Now my problem is when I tried to simulate the rule I am not getting any input screen to enter the data.
ITEMS_TAB is an internal table type of   "PTREQ_ITEMS_WF_TAB_FLAT".
In the rule I have created a container by selecting the radiobutton "ABAP Dict. Data Type" and entered the above reference parameter is it right way?
Is it possible to test the rule independently if I use multiline container as import parameter in my rule? If so can anybody please tell me how to test the rule?
Thank You.
Srija.

Hi Pavan,
                 Thank you.
                 To copy the values I am not getting any input screen to input the values. I observed one thing that the type that I am referring in the Rule is a deep structure. Is this is the reason that I am not getting the input screen to enter the values?
I tested by creating aother rule by taking a field for that rule I am getting the input screen to simulate the Rule.
Can you please suggest if the rule will not work then what I have to do? without the rule how can I get the agents?
Thank you.

How to test the PMS/apprisal template

Hi experts,
We have completed the configuration of Apprisal templete.
With OOHAP_BASIC,PHAP_CATALOG_PA we have completed the process along with status and substatus,staus flow.
I struckup at this juncture.
How to test the entire process after the configuration.
Please advice.
Regards,
Sairam.

Hi Sairam,
To test the PMS process, please follow the below steps :
1. Go to PHAP_CREATE_PA and select your template. Enter the details for appraisee, appraiser, reviewer ( if applicable ) and also the start date and end date. Save the document.
2. Go to PHAP_ADMIN_PA and select the template/appraisee id in the appraisee column in the selection screen and execute. Select your appraisal document and then select from Menu- Appraisal Document->Change Status and select your initial status and sub status.
Now you can login to Portal/R3 with the user and start testing. The substatus will move automatically based on your workflow. Once you complete a particular status say 'In Planning' you need to manually change the status again from PHAP_ADMIN_PA to 'In Review'.
Get back to me in case of any queries.

How to test the connection between DSD backend and DSD connector

Dear all,
I am configuring the MDSD scenario .. and i want to insure that my customization is correct
How to test the connection between DSD Backend and DSD connector ??

Hi Viren,
The problem is:
We have a new BW system. The basis people asked me to check the connection between this BW system and the R/3. There is only one client for now(100). I have logged into 100 and tried executing RSA1 to check the connection, but it gave a message box saying "You can only work in Client 000". Then I have treid logging into 000(just to make sure) and tried executing RSA1. Even here I got a message saying "The SAP BW system must not be operated in client 000". Now, I am not sure of what is wrong in clien 100. I am not sure if I have to do some settings before I access RSA1 or any other BW transaction. Could you please help me in this.
Also, I just checked the RFC destinations in BW. There is a destination created for our R/3 and I have noticed that they have given a remote UserID and password for remote login. I tried to check the Remote UserID in SU01 but there is no userID with that name. Could this be a problem?
Thanks,
RPK.

Please go thorugh this ...
eCATT stands for extended Computer Aided Test Tool (eCATT) which is built is testing tool to test SAP system. By using testing tool we can test the entire business process, and we can also use this tool with a third party testing tool (I am not covering this topic). Execution of every test script ends with a log, which explains the results of the test script.
By using eCATT we can do following operations,
·        Test transactions, reports, and scenarios
·        Call BAPIs and function modules
·        Test remote systems
·        Check authorizations (user profiles)
·        Test updates (database, applications, GUI)
·        Test the effect of changes to customizing settings
·        Check system messages
For more information go to: eCATT::Extended Computer Aided Test Tool (sdn.com)
Here I am discussing fundamentals about eCATT in detail. You can find very good documentation in sdn.com.
To develop a test script in eCATT we need to follow the following steps,
1. Creating Test Scripts.
2. Creating Test Data Containers[16] .
3. Understanding System Data Containers[17] .
4. Executing Test Configurations.
There is a very good web blog on eCATT in sdn.com which explains eCATT with necessary screen shots. To read document click here Blog on eCATT in sdn.com

I done mapping from source to destination as per tech spec in my scenario based on some conditions
i used node functions also..
But my question is how to test the every mapping filed , condition is correct or not, what i used node function working properly or not...
Regards,
Raj

Hi
If you want to check mapping for individual mapping then in design go to test tab and put your data there and then come again on Design tab and click on any target field fro which you want to check mapping then right click on target field in mpping area and click on Display queue and check whether it is expected output for that particular field mapping.

How to test the UDA or Attribute of an ancestor member

Hi everybody !I would like to know how to test the UDA or attribute (I can use both) of the ancestor (or the parent of the parent) of the current member please ?(the current member is on level 0 et the ancestor is on level 2).I tryed some syntax but any result :(Thanks very much for your help... JaspePS : Sorry for my "bad" english, i'm french...

You can try using this IF conditional statement:if (@count (skipnone, (@uda (dimName, myUDA) and @ancest (@currmbr (dimName), -2))) == 1)where:dimName is the dimension of the level 0 member you are testingmyUDA is the UDA you are testingWhat this does is it counts the number of members that meet two criteria. First, it must have the UDA you specify and, second, it must be an ancestor of the current member at a specified level.If the current member has a level 2 ancestor with the UDA, it should return one member.

How to test the process chains

hi sap gurus,
Can anybody tell me how to test the Process chains before i load real time data,i run process chains every morning 6.15 am,before that i want to test every process is linked to another.
thanks in advance.

Hi,
Scheduling the process is the only way to check whether it is running fine or not. The process chains should be checked first in the Dev server and then in the QA server before transported to Prod.
You can also check the process chain using the "check" button to see if the processes are in the proper sequence or not.
There is a "log" button to keep track of the progress of the chain
