Sizing Parameters per application on WAS possible ??

Hi,

On some (J2EE) application servers when deploying an application you can specify sizing-parameters for these applications (eg. application should be allocated a minimum of X Memory and a maximum of Y memory ,...). Is this/will this be possible with SAP WAS ?

Regards,

Igor Vernelen.

    Hi Igor,

    you can set this parameters for all servers generally or only for one server instance of webas with the ConfigTool:

    cluster-data -> instance_IDxxx, tab Servers General.

    Hi Igor,

    Yes, as Andre mentioned you can specify JVM parameters (Xmx, Xms, NewSize, etc.) at J2EEengine instance level using config tool: cluster-data -> instance_ID->Server_ID.

    In case you you want to change J2EEngine parameters like number of threads local to a particular J2EEngine, you still can do it in config tool (for an example changing thread setting, different for a local instance different to the global setting

    cluster-data -> instance_ID->Server_ID->manager->ThreadManager

    Thanks,

    Hi,

    If I understand well, this is per instance on the server. Is it possible to set this kind of parameters per Application ?

    Regards,

    • Hi Igor,

      In a WAS Java environment we deploy J2EE applications to server in a cluster which contains one or more server(s) and one or more dispatcher(s) either on a single box or across multiple boxes. When you deploy an application, it is generally available in all servers. We also can look a cluster as a set of instances (dispatcher+server).

      We can configure different settings for servers based on available hardware, mainly for memory. However, we generally keep the same settings (Xmx, NewSize, etc.) for all servers to make it easy to maintain. However, for academic interests, we can choose different values for individual server and we can use config tool to choose the settings.

      Thanks,

      Swapan

    No I dont't think so. This settings are for the hole server instance. Why do you want to make different settings for different applications?
