Web dynpro console - monitor - JCO Connection pools

If you go to the web dynpro console -> monitor -> JCO connection pools you see a table with information.
JCo Clients MonitorJCO Pools - 12:31:02.992
Name Size Currently used Maximum used Max.connections Max.pool size
Can somebody explain what for example the "Size" and "Maximum used" mean in this table?
And if you have set max.pool size to 20, what things can override this setting in the SAP system?

Hi,
You can follow this link for information on JCO in Web Dynpro Java:

JCO connection pool is exhausted

hi
I am using RFC module in my web dynpro application. When the application is used for sometime, the JCO connection will get exhusted. The JCO connection will not release itself. I can't find any method in web dynpro to release the connection manually. How can I solve this problem?

Hi,
What is scope of the connection. View properties of MODELDATA and METADATA destinations.
You can change the scope of the connection..
or
wdContext.current<BAPI INPUT>Element().modelObject().modelInstance().disconnectIfAlive();
For more ways , give a forum search.. There are a lot of close forum posts.. Gud luc..

How to use a JCO connection pool in an EJB?

Hi *,
I want to build a WebService using SAP Web AS (J2EE Engine) that connects to a R/3 ERP (release 4.7).
I thought of building a stateless session bean that will be deployed as webservice. The session bean shall connect to the R/3 in order to call some BAPIs. I'd like to use a JCO connection pool. But I'm not sure, where I should create and destroy the connection pool. Are the EJB methods ejbCreate() and ejbRemove() the right ones? If so, my businness methods would just have to get a connection from the pool and call the BAPIs, right? If not, what do you suggest?
Another question: I already deployed a bean as webservice. Since not really knowing how to use the connection pool, I created a bean with one business method that creates a connection pool whenever it gets called. But if I have to change something in the bean so that I have to redeploy the bean I can't call my business method anymore, because JCO cannot load a native library once again, as it is already loaded, This leads to an exception. So I have to restart the complete engine everytime I redeploy my bean. Are there any workarounds for this problem? I'm not sure whether this is connected to the wrong use of the JCO connection pool.
Kind regards,
Lars

JCO Connection pooling

hi,
How to create connection pooling in WAS for SAP R/3 System.

Web Dynpro Console Doesnt display any Performance Data

Hello,
I set the JARM parameter to 10 in the Studio. Rebuild, Deployed new archive. Ran the Application and accessed couple of functions.
When I go to the Web Dynpro Console, Trying to display the performance data. But I dont see anything in Applications or Web Dynpro Framework.
I couldnt guess what went wrong. Does anybody know the reason, why didnt display the performance Data.
Thanks,
Sunita.

Hi Sunita,
use this method for getting the performance data.

Best practice for Web Dynpro for Java to connect to SAP HR

What is best way to connect Web Dynpro for Java application deployed in SAP portal to connect to SAP HR ?
Is it good practice to connect to underlying SAP database ( eg oracle) directly to get the data or is there a better way ?
This below article describes to connect to external DB, however Is there any other way for SAP HR ?
http://wiki.sdn.sap.com/wiki/display/WDJava/WebDynproApplciationwithDatabaseMS+Access

Hi,
There are 2 supported ways :
First is to use JCO connections to call abap RFC enabled function modules. (BAPIs for example)
Second is to call SOAP web services (HR enterprise services for example)
You should never access directly database tables...

Problem with JCo Connection Pool

Hi,
I have a problem with using an RFC Model in my WebApplication. So sometimes the access to the function block works, and sometimes it doesn't work. Now I know, that there is a problem with the connection pool. Look at this message:
com.sap.mw.jco.JCO$Exception: (106) JCO_ERROR_RESOURCE: Connection pool WD_X24_MODELDATA_DEST_CPIC_REKTO_DE_useDefinedUser is exhausted. The current pool size limit (max connections) is 10 connections.
So it looks like a problem with closing the JCo Connections after using. Do know where the problem is? Because I'm using many other function blocks with no problems.

Hello,
You need to increase the pool size via Visual Administrator.
Server 0 -> Services -> JCO RFC Connections.
Change the pool size from there. I believe a restart is in order.

Web Dynpro: several navigation links connect to one outbound plug of a view

Hi,
I have two questions in general Web Dynpro. (I have not found precise answer for the question yet)
1) What should happen in the following case?
We have three views in a component. The outbound plug of the first view is connected to the inbound plug of the second and third view via navigation links. Which view should appear, if i fire the outbound plug of the first view?
Some documentation says, this case is not allowed, some documentation says it is allowed...
2) If the previous case is allowed, what should happen in the following case?
In a child component, a window outbound plug is connected to a view inbound plug. Beside this, I implement an inbound plug of the window, where i fire this outbound plug of the window.
Now, the interface view is embedded into a parent component window. In the parrent component I connect the outbound plug of the interface component to an inbound plug of a parent view (which is also embedded into the window). I also connect an outbound plug of the parent view to the interface view inbound plug.
What will happen if I fire the parent view outbound plug? Will the parent view or child view appear?

Hi Huszar,
I'm a newbie and found your question interesting. So I played a little with this issue and hope I found something to help you.
But I wonder in why you want to use such a constellation the first place. What is your purpose? For me the idea itself doesn't make much sense... Did you by chance actually think of one of the following purposes:
You want two different action elements (e.g. 2 buttons) to fire different conenctions. Then you should use different outbound plugs. Connect the two buttons and the two links to different methods so that the corrsponding plug and button have the same method.
You want to decide by value or state which view to show. Then you should use two different outbound plugs as well and decide in the button's event handler mehtod which plug to fire , e.g.: if <condition> then <firePlugA> else <firePlugB>.
Generally, if you connect two views in a window via link you must chose a method to use or create a button. If you chose a method (event handler) the effect in the Java file is that the method (onActionButtonX()) will call the corresponding firePlugOut-method.
Unfortunately in the firePlug-method itself there was no hint about the plug's destination. As I connected the same method for button and two plug targets, Web Dypro for no obvious reason always chose the same target. I did not find a possibility to directly chose the target from one outbound plug, so I guess this information is stored somewhere in the background logic.
Did I get the point or did you think of something completely different? Or maybe you just asked theoretically? In that case I don't seem to get the idea.
Kind regards,
Jana

Problem in connecting JCO destination in web dynpro

HI all,
I was installed sneak preview of Net weaver 6.4,
I want to do some web dynpro (java) programs which connect to back end systems.(R/3 system).
The R/3 system which I want to connect is at remote place, i have connectivity to that R/3 system using VPN connectivity. With this I am not having any problem. Since I am able to connect using User name and password, and able to do some transactions like RZ70, etc.
I developed an application which calls COMPANY_CODE_GET_LIST (BAPI function).
for the above requirement what I did was
(1)I created SLD setting.
(a)Web as Java (I am not having any problem to
Create this.
(b) Web as ABAP.
When i am trying to create
This, there are some steps like i need to go to SAP log in and I need to run the transaction RZ70. For this i need to create an enter in visual administrator>JCO RFC Provider>runtime-->Bundles i need to create an entry for RFC destination as well as Repository.
under RFC destination there are some fields which i need to enter those are (a)Program ID as mySLD (b) Gateway Host as 10.10.10.125 (c)Gateway service as sapgw00 (d)Number of processes as 1
Under Repository (a) Application server host 10.10.10.125 (b)system number as 00 (c)Client number as 100 (d)Language as en (e)user as ABCD (f)password as 1234
I haven't choused the check boxes Local bundle and Unicode and pressed the set button. So like this i created the RFC destinations. under the properties tab there is a property called RFC_DEFAULT_DESTINATION by default it was false so i made it as true. .
I also went to SLD Data Supplier,under Runtime tab , HTTP Settings , I mentioned
(a)Host: pava-vis75
(b) Port: 50000
(c) user: administrator
(d) password: abcd1234
RFC Settings, I mentioned as
(a)Gateway Host: 10.10.10.125 (which is SAP R/3 system)
(b)Gateway Service/Host: sapgw00
CIM Client Generation settings, as
(a)Host: pava-vis75
(b)Port (http/https):50000
(c) user: administrator
(d) Password : abcd1234
I tested the CIMClient Test by click the the button. I got the successful message.
Then I came back to HTTP settings and clicked the button with tilted arrow mark [This triggers data transfer to system landscape directory], for this also I got a successfully message.[data transferred successfully]
Next I been to SAPLOGON and went to RFC Destinations by using sm59 transaction. There under TCP/IP connections i been to SLD_NUC , opened this by double clicking that and under Technical settings for Program ID I had given the ID which I created at visual administrator [JCO RFC Provider] which is mySLD , under gateway options for Gateway Host as 10.10.10.125and Gateway service as sapgw00 then i tested the connection, it was also successfully.
Then I opened the SLDAPICUST and i created a new entry for maintaining the SLD Access Data by giving some couple of entries as
(a)Alias: vissldtest
(b)Host Name: pava-vis75
(c)Port: 50000
(d) user: administrator
(e) password: abcd1234
Then saved it.
Next I created sapmsUV0 3600/tcp entry at
WINDOWS\system32\drivers\etc\services file, and also there are some required entries which are already existing those are sapgw00 3300/tcp to sapgw99 3399/tcp , another entry starts from sapdp00s 4700/tcp to sapdp99s 4799/tcp , next entry starts from sapgw00s 4800/tcp to sapgw99s 4899/tcp and sapmsJ2E 3601/tcp .
I restarted the system, as well as server.
Now my problem is when I was trying to create JCO destination at web dynpro content administrator. For that I navigated as create JCO Destination Deployed Contentlocal-local/CompanyCodeGetList-Applications CompanyCodeGetList
I Choosed the JCO Connections tab- there are 2 entries those are
(1) COMPANY_CODE_MODEL
(2) COMPANY_CODE_RFC_METADATA
So I started creating connection for COMPANY_CODE_RFC_METADATA.
First one is
General data Name : COMPANY_CODE_RFC_METADATA
Client : 100
I didnt changed any default JCo pool configuration.
J2EE Cluster
There is a check box called Use Local J2EE engine J2E on pava-vis75 so I choosed that.
Connection Type
Dictionary Meta Data and application Data
I choosed the first one.
Then
Msg. Server Connection
Security
After these, I tried to test the connection by clicking the Test Connection.
It is saying the error as
First time
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=v011 GROUP=DEFAULT R3NAME=UV0 MSSERV=sapmsUV0 PCS=1 ERROR service 'sapmsUVO' unknown TIME Fri Jul 01 07:20:41 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1

Can any body please help me to solve this problem.
From past 1 week on wards I have been trying to resolve this. But in vain.

It does not necessarily mean that you have to change that parameter. I read that blog as I had a similar problem, and after reading it and understanding the reasons and possible causes for the error, I found that my particular problem was that I was using "PUBLIC" as the logon group in my JCO destinations, but such a group does NOT exist at my backend. I went to transaction SMLG, had a look at Logon Groups, noted that there were none other than SPACE, figured out that I had to include that information in SLD (Web AS ABAP tech. system --> Message Server --> Logon Groups), put it there. Voilá. It works.
Edit: That SPACE logon group is the one I had to use at JCO destinations. Sorry I forgot to mention that one...

Eduardo.

How to setup and use connection pool in Web AS 7.0?

Hello SDN!
I'm developing a Web Dynpro Java application on SAP Web AS 7.0 My app using a couple of DAO classes as model instead of EJBs. These classes perform direct requests to database using JDBC drivers.
I've read that many of web-servers use their own connection pools. So I want to know:
1) how I can setup connection pool in SAP Web AS ?
2) how I can call this pool in my application?
Could you please give me some examples?
Regards, Lev.

Monitor Connection pool

Hi,
I am using ODP.Net from Oracle 9i client talking against Oracle 9i. Using in VS2005/.Net2.0.
I am successfully using connection pooling in my applictaion behind web services running in IIS. My front end calls the web service, and the webservice uses the connection from the pool and retrieves data from the database. This works great. I checkd this by looking at the number of open connections in the v$session table.
I am wondering is there any other way of monitoring the connections/pool on the IIS web server machine. Is there any other app or does ODP.Net have any counters for the connections and the connection pool which we can monitor.
Thanks

Hi,
I think I have the answer. I just have to open up active connection pool in the
administration console and click on Monitoring.
Please correct me if I am wrong.
Thanks and best regards,
Jaya

Hi all,
Is there a way to monitor active connections from Weblogic administration
console
(or from anywhere else)?
I have configured a connection pool with minumum capacity=50, maximum
capacity=100
and capacity increment = 1.
Is there a way to find out how many connections have been used up from
the pool
at a given time?
Thanks in advance.
Best regards,
Jaya
