How to configure datasync proxy for a cluster

Hi,
I am in the process of configuring Portal on a cluster and can not get the sync server
to syncronize the data with the managed server's repositories.
I configured "SyncServer" as a managed server and deployed a separate webapp "datasyncproxy",
which is a copy of the datasync webapp. I configured the DataSyncServlet parameters
to communicate with the managed servers' datasync applications.
For some reason the master repository running on "SyncServer" does not recognize
that it needs to syncronize with managed servers. My master repository on the "SyncServer"
indicates that it is using read-only JDBC persistence store. The deployment guide
document states that I should set java.lang.System property: data.sync.jdbc.master.dr=true,
but I do not know where to do it.
Could anyone help?
Thanks
Mike

Thanks for the news Daniel,
I've heard these news from your colleagues at CO office. They are keeping me
in the loop.
It would be nice however if somebody at BEA could update the portal
deployment guide. There are too many inconsistencies related to deployment
on a cluster.
Thanks again

Mike,
You may be pleased to know that we've spent some time on this for the 7.0
release.
In WLP 7.0 the DataSyncServlet running on an admin machine in a clustercan
auto-discover DataSyncServlets running on managed nodes. This allows youto
just deploy the out-of-the-box datasync.war to all your cluster nodes - no
need to set any system properties or WebApp properties. We still supportthe
explicit registration (as in 4.0) for backwards compatability and to allow
customers to set up sync networks that cross clusters or for more advanced
configurations.
Sincerely,
Daniel Selman

Good news, issue is RESOLVED.
Several things need to be done:
1. Copy p13n_util.jar to the WEB-INF/lib directory under the datasyncwebapp, which
is used as a proxy. This needed to be done because of the problems withthe class
loader.
2. The BEA Deployment guide has several discrepancies, so the parametersfo synchronization
with managed servers should be defined for the webapp itself, not for
the
servlet.
This could be done using the deployment descriptor edit from the
console.
Also, the
document states the name for URL parameter as "notifiedURL" (incorrect),should be
"notifiedUrl".
3. In the startup parameters for the WLPortal server, running the proxydatasync
application the following parameter should be added:"-Ddata.sync.jdbc.master.dr=true".
4. Finaly, the datasync connection pool and TX datasource should bedeployed on all
servers (sync server and managed servers).
It took us 2 days to figure this out, but it works well now.

  • How to configure release procedure for rate contracts release

    Dear all,
    How to configure release procedure for rate  contract following are the requirements
    they are two release codes c1 & c2 <=100000,>=100000
                    if  c1 is not there c2 has to be approved
         Change in the value of the rate contract contract
         Change in the validity of the rate contract
         Addition of deletion of line items
    While using a non u2013 released rate contract in the PO an error message should shoot out.
    Also the logic should be changed while using the rate contract in the PO.
    The usage of the rate contract should be till the validity of the rate contract. i.e. the measurement should be end date of the rate contract and the PO creation date and not the delivery date of the PO. &
    It should be possible to refer existing valid rate contracts in purchase orders.
    Regards,
    bhaskar

    Hi,
    In SAP rate contract is known as value contract denoted with wk. The release procedure for rate contract is same as that of other contracts and scheduling agreements. The tables  for contracts will vary with SA (Scheduling agreement) .You may try and maintain condition records based on the customer combination and maintian the validity date of condition records as per your requirement.For contract and PO will have the same header/item table as EKKO/EKPO, and the release
    class in standard is the same FRG_EKKO, you can use the same for contract.
    To distinguish if it's a contract or PO, EKKO-BSART can be used.
    For contract EKKO-BSART will be MK or WK, while PO will have NB/UB etc..
    You can restrict the document type to set up the release strategy for only contract.
    Of cause, you can also create your own release class Z* for contract copying standard
    one FRG_EKKO via CL01/Class type 032, and then assign the class Z* to customizing:
    OLME:
    -> contract
    ->Release Procedure for Contracts
    ->Define Release Procedure for Contracts
    ->Release Groups
    If you have already created the PO release class.
    Assign a new chracteristic of Document Category -BSTYP
    Please check below link for detailed release procedure. I hope this wil help you out .Thanking you.

  • How to configure a proxy server for Windows Azure Tools in Visual Studio 2013

    Hi Visual Studio/Azure Tools team
    I would like to use the Windows Azure tools in Visual Studio 2013 to manage my Azure Web sites (Server Explorer -> Windows Azure -> Web Sites) from within my corporate network which is secured using a proxy server. Unfortunately, I am not able to use
    the Windows Azure tools since the required HTTPS connection to windows azure is not going through the default configured proxy. Instead, Visual Studio tries directly to connect to port 443 which is blocked by our corporate firewall (and yes: there is no way
    around using our proxy server). Other visual studio features like NuGet, updates, etc. work fine and use the configured proxy server. 
    So my question: How can I configure visual studio respective its Azure tools to use a proxy server instead of a direct connection? I already tried configuring the proxy server within the file devenv.exe.config but this doesn't show any effect for Windows Azure
    tools.
    Regards
    tschaena

    As we have very similar problems I consider the found solution a work arround an existing problem which will not work if corporate FW policy does not allow such changes.
    In my mind, any tools in charge of dealing with some sort of FW protocols should deliver the following information, should make it absolute clear how to setup that the request packages are setup rigth at the first time.
    a) proxy server
    b) proxy port
    c) proxy user
    d) proxy users-password
    e) proxy.auth.Preference="BASIC"
    And for moste tools (including Visual Studio and AZUR Tools) it is absolut unclear
    a) how to setup that on a per tools basis
    b) OR who inherits this information from whom    i.e. use the same as IE does, what if we use FireFox or any other browsers?
    I understand that developers requested to cure such problem areas will often have difficulty to gain all required elemenst used to realy test the solution.
    But I can tell you: I loos more time figthing down the FW setups for my clients. WHat I do at home in a sniff, takes ages to be realised by all the various clients on the market where each has to deliver the same sort of information but actually does not,
    or has it just somewhere, but not in the vicinity of the demanding user.
    Good examples i.e. NetBeans IDE where the Option Menu shows very clearly what information is required to pass through a FW/Proxy; but even there, the hint to start with a BASIC authentication schema is not part of this OPTION menu and must be added a JAVA
    environment value. But at least, it works.

  • How to configure a Proxy in OSB with Digest Authentication?

    Hello, Guys.
    I need a help with this subject.
    I have a demand to configure a Proxy in OSB 11.1.1.6 with Digest Authentication. I'm using a Embedded Ldap with Identity Asserter.
    I'have configured a DefaultAuthenticator and the DefaultIdentityAsserter to support Digest Password and create a new LdapIdentityAsserter pointing to my embedded Ldap.
    When I'll create a new Proxy, in the security options, i can see the digest options to authenticate my username and password. I selected the one of all the options, but in the time of the Proxy test the authentication didn't work.
    Could anyone help me?
    Thanks you.

    Unfortunately, a reference trigger can't be used for continuous acquisition after the trigger. The maximum post-trigger count is either 2^24 or 2^32 depending on your hardware. Depending on your sampling rate and how many samples you expect to acquire before issuing a software stop, using the max post-trigger count may be sufficient for you. There are a couple of other options I can think of that you might want to try:
    1.) If possible, play with the trigger condition such that it occurs at the start of your pre-trigger data and use it as a start trigger instead. I suspect this may not be possible.
    2.) Set up a continuous acquisition and implement detection of the trigger condition through software. This is more software work and is more CPU intensive than the hardware solution, but it can definitely be made to work.
    3.) With some creative use of the counters, you may be able to latch the sample clock number that trigger occurred on. This would allow you to setup a continuous acquisition and use the hardware to tell you where the trigger occurred instead of figuring it out in software. What I'm thinking is you would set up a buffered event counting task with the ai/SampleClock as the timebase source of the counter and the trigger signal as the sample clock of the counter. By reading the first count value, you should know which AI sample the trigger occurred. From there, you can seek to the right position in the buffer and begin reading data indefinitely.
    Good luck!

  • How to configure simultanous access for 11i application

    Hi All
    We have one existing 11i application instance on node grid1.In which we start the servicess from apps user.
    In our same we want another node for the same application in which we will start the servicess from another user(merge)
    For that we perfrom the following steps
    1.Copy the APPL_TOP,COMMON_TOP,ORA_TOP(8.0.6,iAS) from node "GRID1" to diffrent node "GRID2"
    2 configure the GRID2 node using adcfgclone.pl utility(we have configure new node for WEB and FORM Server)
    3 We perfrom the modification in the following files ON GRID2 .
    i Identify 'FNDNAM=apps' statement in $FND_TOP/secure/<context>.dbc
    and replace with 'FNDNAME=merge' to connect to MERGE schema instaed of APPS.
    ii. Go to the last line of $APACHE_TOP/jserv/etc/zone.properties file
    and identify 'schema=APPS' statement and change it to 'schema=MERGE'
    iii. Identify below lines in $APACHE_TOP/modplsql/cfg/wdbsvr.app file
    password = apps
         username = apps
         document_table = APPS.fnd_lobs_document
    and replace with modified below lines
    password = merge
         username = merge
         document_table = MERGE.fnd_lobs_document
    6. For redirecting user's request to new Application Server server, we
    changed the following 4 system profile options with proper URL and port
    at responsibility level only for the responsibilities,
    which we use for Merge views.
    Profile Options
         Application Framework Agent
         Applications JSP Agent
         Applications Web Agent
         Apps Servlet Agent
    When we are able to start the services on GRID2 node,but at the time of login we are getting invalid user name/ passwd error
    Please let us know is there any way to access application other than apps user

    well thank you very much .I know how to define a DataSource inside Weblogic Server.
    But i am confused over one issue
    When We are going to use Container Managed EntityManager inside the SessionBean the persistence.xml file looks like this
    *<persistence>*
    *     <persistence-unit name="RamsEJBPU" transaction-type="JTA">*
    *          <jta-data-source>myJtaDataSource</jta-data-source>*
    *     </persistence-unit>*
    *</persistence>*
    But in some cases it looks like as shown below :     <persistence-unit name="RamsEJBPU" transaction-type="resource-local">
         <provider>org.hibernate.ejb.HibernatePersistence</provider>
                        <properties>
                   <property name = "hibernate.connection.driver_class" value = "oracle.jdbc.driver.OracleDriver"/>
                   <property name = "hibernate.connection.url" value = "jdbc:oracle:thin:@localhost:1521:orcl"/>
                   <property name = "hibernate.connection.username" value = "CHENNAISPAT"/>
                   <property name = "hibernate.connection.password" value = "CHENNAISPAT"/>

    Hi,
    I want to test subscription. My problem is how to configure the mail server.
    As to my understanding, we need first configure mail server, then the user can choose "Subscribe" in the Details screen of a folder.
    My steps are:
    1. In KM - CM - Utilities - Channels, specify SMTP server, userId and password.
    2. In KM - CM - Utilities - Channel originators, set the Original address for notificator.EMAIL.
    3. In KM - Collaboration - Groupware Transport - Mail Transport, specify SMTP server and sent message folder.
    After that, when I choose a user and click "Send email", it failed saying "Failed to communicate with SMTP server when sending the email.".
