Administering data grids

You can create three different types of data grids: simple data grids, session data grids, and dynamic cache data grids.

  • Creating simple data grids
    With a simple data grid, you can perform create, retrieve, update and delete operations. In particular, you can use the simple data grid to allow faster access to data that is stored in a database.
  • Creating session persistence to a data grid
    To configure your WebSphere Application Server application to use the appliance for session management, you can either select the appliance when you are installing a new application, or you can update your existing application or server settings to use the appliance.
  • Creating dynamic cache data grids
    You can use IBM® WebSphere DataPower XC10 Appliance to store data from your WebSphere Application Server dynamic cache. By setting up this capability, you can enable applications that are written with the Dynamic Cache API or applications using container-level caching (such as servlets) to use the features and performance capabilities of the appliance.
  • Configuring the maximum capacity of a data grid
    You can define a maximum capacity for each data grid in a collective. Configuring a maximum capacity limits the amount of data storage that a particular data grid can use. The capacity limit ensures that the available storage capacity for the collective is used in a predictable manner.
  • Securing data grids
    After you create your data grids, the security of the data grid is disabled by default. You can change the security settings for a data grid to restrict access to a certain user or group of users.
  • Clearing data grids
    You can permanently delete all of the entries in a data grid. You can clear the data grid to remove stale information or test entries.
  • Querying and invalidating data
    You can use the query interfaces in the monitoring console and in the xscmd utility to retrieve small sets of keys from a map and invalidate sets of data.
  • Removing data grids
    If you want to clear the data grid data, you can remove the data grid and then recreate the data grid.
  • Administering with the xscmd utility
    With xscmd you can complete administrative tasks in the environment.
