Connection Doubt

Hi Guys
Here Client , what is he asking that ,
can we connect from one R/3 system to two BW servers?
with 1. same versions in BW servers
2. always connection for two BW servers
3. no data pullung at the same time
Please tell me, is it possible or not , if yes just geve me brief discussion.
if any small materail just send to id : [email protected]

Nexus 5548UP / FEX Connectivity doubt

Hello Everybody,
Some weeks ago, we decided to do a connectivity test with our nexus equipment. The topology was fairly simple, only one Nexus 5548UP, no vPC domain configured. 2 Nexus 2248TP Fabric Extenders connected to the 5548UP. Finally, a server, doing NIC teaming, ACTIVE-ACTIVE in a PortChannel config, one link to each Nexus 2248TP Fabric Extender. Topology attached below.
My understanding was that the FEXs were remote line cards, so what we are doing here is like adding 2 linecards to a moludar switch like a 6500 and creating a PortChannel using 1 link to 1 linecard, and 1 link to another linecard.
To my surprise, this was not allowed.
I tried to find and explanation why this could not be configured, but nothing found.
Anyone has an idea why this could be happening?
thanks in advance,
Fernando

PI' RFC Connection pool doubt.

Hi PI exports:
i have a doubt about pi' RFC Connection pool ,pi RFC receive channel can set the conn pool size ,but when start the rfc receiver channel ,is there always only one Connection pool ,or there is only one Connection pool instance?
thinks
Edited by: kevin liang on Oct 19, 2009 6:45 AM

Hi,
Connection poolins size means how many number of connection you want to make open to send data to ECC, We can define maximum number of connection in Receiver RFC Adapter,Go to additional parameters section and define Max Number of connection give the number there,thats it.Internally it works as Connection poolin mechanism.

Doubts regarding db connection with encrypted password usage in sandbox

Hi All,
We have setup the db connection using configuration file. The configuration file contains db connection information including the encrypted password.
Below are my doubts:
1. If we are going to import the ETL project in zip file directly into the sandbox can we run the graphs directly or we need to check how the password which is encrypted in configuration file will be decoded.
2. Can we directly modify the configuration file for db connection like db connection,user name and password. Suppose I want the graphs to run in some other database which is not specified in configuartion fiel .Can I directly update that?
3.Is it possible to change the encrypted password in the configuration file in the sandbox. Is it that we need to create the project in Integrator Designer, change the password using the Integrator Designer, and then copy the encrypted password into the configuration file in sandbox, or the Endeca provides a functionality to allow user to directly change the password in the sandbox on the Integrator server.
Can someone please let me know their comments on above.
Thanks in Advance.

Amrit

Hi, i have a doubt, i want my pdf files to be sync with the cloud but im afraid they wont open when not connected to the internet so my question basiclly is¿ can i store the documents on my device sd and edit them and when i get a internet connection they

Hi, i have a doubt, can i have my pdf files on my sd, edit them while in class with no internet connection and when back online they will sync, all i want is to able to open my files without wifi and edit them but when back online sync their changes so i can see them in other device

You can cache the cloud documents that you most often read by opening them once when the network is available. Edits made to these documents would be automatically synced back to the cloud if the network is available. If for any reason the network is not available, these would be synced the next time network becomes available.

Doubt in connection pooling

Hi,
I have a doubt in connection pooling.
I we create 100 connections in a connection pool, when do the connections created or assigned? Is it during the login time or during there is a request for the connection?
Please explain the doubt in detail.
Thanks

It depends on connection pool implementation.
Anyway you should not worry about it.
In general some connections created right away and some created after if required. You should be able to configure your pool.

Doubt in pass of connection by parameter

I have a technical doubt about pass of parameters. I have a method to which I pass as parameter a connection with database like 'public void ejecutarSelect (Connection with, String selec)'. The connection comes opened to the method, and it only executes the select. The connection is closed out of the method.
Here my doubt comes. In java all parameter passed to a method is for value, I mean, to the beginning of the method is created a copy of the variables passed by parameter and at the end of the method it destroys them. But in case of the connection, does the method copy the pointer to the connection or really it clon the connection with database? I am interested becuase I want to know if I would be leaving connections open.
Thanks.

Java passes all parameters by value. Parameters hold primitive types and Object references (not Objects). In your case the Object reference is being passed by value but that in effect causes the Object (Connection in your case) to be passed by reference.

Try temporarily disabling your firewall and see if you are then able to access the iTunes store.

Doubts concerning External Connection Pool

A few questions:
1. How can I set up an external connection pool with toplink? or in another words, assuming that I have successfully configured a connection pool (and a datasource) on my weblogic app-server, how do I configure Toplink to use the same?
2. I am trying to achieve the above (refer point 1), by defining my custom connector (by extending TOPLink.Public.Sessions.DefaultConnector). The custom connector provides connections using the dataSource.getConnection(). Now, the question is
- Where will the pooling happen in this case? i.e. Will Toplink use its own connection pool (populate its own connection pool with container managed data source), and issue connections (container managed) from there or will it make use of the container managed pooling (and ask for connections from the container managed pool, as and when required)? The subtle difference being, weblogic will not be able to validate a connection before issue in the former case.
3. This question is similar to point 2, but talks in terms of a practical example. Assuming that if I am using the custom connector successfully in my code, then if I pull out the network cord and reconnect again, I expect the container to provide me with a valid connection (as weblogic can be configured to perform a validity check on a connection before issuing). I am getting a 'connection reset by peer' error in my application (indicating that either the container fails to provide a valid connection, or toplink does not use the container managed pool effectively). I guess, Toplink still uses its own pool but this time it is pooling container managed dataSources. Since the connections are issued from Toplink and not container, here is no validation/reconnection happening for the connection, before issue. Please comment if I am thinking in the right direction or not. If not, how you can explain the above failure?
4. My aim is to utilise the container's connection pool, and Toplink's ability to perform the rest of the things (including transactions). Is that possible?

Vikas,
TopLink can easily be configured to use the external connection pool of an server. This can be accomplished with API but more commonly using the sessions.xml configuration file for the SessionManager. In the product we ship examples for WLS that make use of data sources configured in the server. The portion of the sessions.XML file in question is:
          <login>
               <user-name>weblogic</user-name>
               <password>weblogic</password>
               <datasource>java:comp/env/jdbc/ejbJTSDataSource</datasource>
               <non-jts-datasource>java:comp/env/jdbc/ejbNonJTSDataSource</non-jts-datasource>
               <uses-external-transaction-controller>true</uses-external-transaction-controller>
               <uses-external-connection-pool>true</uses-external-connection-pool>
          </login>
          <external-transaction-controller-class>oracle.toplink.jts.wls.WebLogicJTSExternalTransactionController</external-transaction-controller-class>
This sets TopLink up with both data source access to the JTA and non-JTA connection pools. The full example also includes a domain where the data source is configured.
When TopLink is using the connection pool of the server (external connection pooling) it will not pool its own connections. TopLink will request a connection from the pool each time one is required and release it back when done. This leaves the server responsible for the number of connections available and also for supporting database re-connection.

Some doubts in using resource-ref,connection pool n Data-source

Hi all ,
I need little bit clarification in the following points.
1) Does the connection pool which is created can be displayed in JNDI Tree???
I am seeing only DataSOurce in the JNDI Tree Only.
2)In case of Bean Managed Persistance, in ejb-jar.xml,
I had given the following info.
<resource-ref>
         <res-ref-name>ramukkDataSource</res-ref-name>
         <res-type>javax.sql.DataSource</res-type>
         <res-auth>Container</res-auth>
     </resource-ref>Does the <res-ref-name> refers to Datasource Name??
In weblogic-ejb-jar.xml
<reference-descriptor>
       <resource-description>
          <res-ref-name>ramukkDataSource</res-ref-name>
          <jndi-name>ramukkpool</jndi-name>
       </resource-description>
     </reference-descriptor>Here <jndi-name> refers to connection pool as per weblogic bible book.
If so when i deployed my ejb into the server iam getting Datasource cant be found.
If i had given like the following,
In ejb-jar.xml
<resource-ref>
          <res-ref-name>jdbc/ramuJndi</res-ref-name>
          <res-type>javax.sql.DataSource</res-type>
          <res-auth>Container</res-auth>
     </resource-ref> In weblogic-ejb-jar.xml
     <reference-descriptor>
          <resource-description>
           <res-ref-name>jdbc/ramuJndi</res-ref-name>
           <jndi-name>jdbc/ramuJndi</jndi-name>
       </resource-description>
    </reference-descriptor>Then only my ejb code is successfully deploying doing some work which is as per xpectation.
Can any body tell why I have to give the same name for <res-ref-name> n <jndi-name>??
I am working on this problem from last one week. Still not found the solution.
Connection Pool Creation
GENERAL::
Name : ramukkpool
url : jdbc:mysql://localhost:3306/test
Driver Classname: com.mysql.jdbc.Driver
Properties :
user = root
Password = XXX
create
TARGETS::
i had shifted myServer from left side to right side n clicked >>Apply
(Techncially can we say this as deploying the connection pool into server ???????????
If not how to deploy the connection pool into server??)
I did not get any errors in the console.
Now i am creating a datasource
CONFIGURATION:
Name : ramukkDataSource
JNDIName: jdbc/ramuJndi(Does we have to follow this convention only?? i.e JNDIName should start with jdbc/ only)
PoolName: ramukkpool
create
TARGETS::
I had shifed myServer from left to right n >>Apply.
Now also i did not get any errors in the console.Thanx(in advance),

I have read the documentation.
I changed my class to oracle.jdbc.pool.OracleConnectionCacheImpl from
oracle.jdbc.pool.OracleConnectionPoolDataSource
I observed in the EM that the Open JDBC Connections and Total JDBC Connections are the same. When I used oracle.jdbc.pool.OracleConnectionPoolDataSource my Total JDBC Connections was increasing and Open JDBC Connections remains 0.
My question still remains unanswered, could some kindly help.
Q? I have defined a data source in JDeveloper using
oracle.jdbc.pool.OracleConnectionCacheImpl
In my java bean I am using the code pasted below to make a connection to database.
Can some one tell whether I am using the correct method of connection pooling mechanism or do I need to make some changes? This application uses JSP and used by lots of people which hits database very frequently.
Any help is highly appreciable.
Thanks in advance.

Doubt about sys fans and connection of water cooler pump

Hello, I have a motherboard MSI Z97 gaming 7 and need to know which connector you guys recommend connecting the water cooler pump H60 Corsair: sys fan or cpu fan?
I want to connect the pump in the sys fan 1, 2 or 3, but need to know if I can put the SYS Fan running at full speed 100% for some bios option, it is possible? So I can leave the option CPU Fan 1 and 2 free for fans.

Quote from: madmecca on 14-May-15, 06:56:08
I have my h100i fans on cpu 1 and 2 and pump on system fan 3 no problems
You can put the sys fan running the pump at maximum speed?

Need Help: Connecting to Repositroy(Reply to this thread is my doubt only)

Hi,
I am using WLP 10.0
When I open my WLP admin page under content management tab I can see two repositories namely Community_repository and Shared Content Repository.
I created my application (portal application) and created a jsp which uses content API's to fetch the content from these two repositories.
However from debugging I found out that my application does not know anything about these two repositories.
Can anyone provide pointers as to how to connect to and fetch content from WLP repositories.
Also the two repositories that we see on WLP admin page. Does these repositories exist for all the application or they are configured for some selected applications(groupspace) only?
I am really confused.
Please guide.
Shakti
Edited by pshaktig at 09/17/2007 5:10 AM

This is in continuation to my previous post.
I created a portal application and portal web project in workshop.
When I try to connect to the content management system of Weblogic portal, I fail and this is the thing going on from last few days.
Today I was able to successfully create a node and add content to it through my portal application. But again I could do it only for the BEA Repository.
I was not able to access any of the defined repositories (Shared Content Repository, Community_Repository)which comes packaged with your WLP 10.0
Please help
