An independent auxiliary storage pool (IASP) is a collection of disk units that you can bring online or take offline independent of the rest of the storage on a system. IASPs contain any of the following:
Each IASP contains all of the necessary system information associated with the data it contains. So, while the system is active, you can take the IASP offline, bring it online, or switch between systems.
For more information, see Independent ASPs and User ASPs.
You can use the "database name" JDBC property or the setDatabaseName() method from the AS400JDBCDataSource class to specify the ASP to which you want to connect.
All other Toolbox for Java classes (IFSFile, Print, DataQueues, and so on)
use the IASP specified by the the job description of the user profile that connects
to the server.
