How can I initialize a web application in a cluster

Our test environment is a single node, but we must move to a clustered environment. We have a database initialization, what we do with a "Startup servlet' with the marker to load at startup.

Now how does it behave in a clustered environment? The servlet will be called once or once a node?

Should review us the startup initialization? Are there methods recommended for clusters of Weblogic regarding the start-up of initialization?

BTW: Weblogic 10.3

see you soon,
Rob

Servlet init() will be called by every JAVA virtual machine, the application is in, no matter if it is in a cluster or not.

If you want to once by the behavior of the cluster, you should consider something like a Service Singleton, who is outside your application OR use something like Oracle coherence in your application that allows you to easily check if initialization has already occurred in another Member of the cluster.

  • How can I use a web application to provide me with the results of a matrix?

    I have a need to set up a search based on a matrix type area. It is a matrix that shows a list of the postal codes to the bottom of the left column and a list of products across the top, and the corresponding field in a product and a postal code is the freight rate.

    for example

    Product 1 product 2 product 3 4

    1234     $10               $12               $14               $16

    4567     $11               $11               $13               $17

    5678     $55               $54               $27               $35

    If 4567 for product 3 freight rate is $ 13.

    So what I want is a drop-down menu for a customer to choose the product, then a field to enter their zip code, and the search result will be the freight cross reference rate.

    Is this possible? If so, can someone guide me as to how this would be?

    Throw this open to the community for the chip, but off the top of my head... think of something along the lines of:

    Create web applications 3,

    1. Product (the fields product name & ProductID)
    2. Postcode (box Desc fields & zip code)
    3. Freight rates (fields FreightRateID (composed of ProductID_ZipCode), freight rates)

    Create a search form web app for Web App freight rates with:

    1. Select product, with options of web app 1 using value ProductID.
    2. Select ZIP Code, with options of web app 2 using postal code for the value.
    3. Hidden FreightRateID field.

    Once a visitor has chosen their product and their zip code using javascript concatenent the ProductID selected with selected postcode.

    This will produce a FreightRateID (for example PROD1_4567), which can be loaded in the hidden field on the FreightRateID.

    Once submitted, it will search the Web app for a freight rate that corresponds to the selected product and zip code, IE. FreightRateID.

    To facilitate the entry of freight rates, maybe add 2 data source fields to the web application of freight for the goods and postal code rate.

    Then, create a front-end web app add/edit (via a secure area) to grant access is done by:

    Select product, select ZIP Code then enter freight rates.  (FreightRateID can be created and filled in same way as the above search)
