RMI Jobs

Remote Method Invocation (RMI) is the Java version of a Remote Procedure Call (RPC), which is a technology that lets a program request a service from another program located in another address space. That address space could be on the same computer or on a different one.

RMI jobs let you set up interaction between Java objects on different computers in a distributed network. Using an RMI job, you can access a remote server and invoke a method on a Java object. A method is a programmed procedure that is defined as a part of a Java class.

Note: To run these jobs, your system requires CA WA Agent for UNIX, Linux, or Windows and CA WA Agent for Application Services.

RMI jobs support method calls to remote objects that can involve passing parameters. The parameters can be actual values or a serialized Java object passed by another job. When the RMI job invokes a method on an object that passes parameters, the parameters are passed to the remote object and the returned serialized Java object is stored on the agent computer in the spool directory or in a destination file you specify.

RMI uses a naming or directory service to locate the remote object on the remote server. To define an RMI job, you require the naming class of the Java object you want to invoke a method on. That naming class takes a name that is a java.lang.String in URL format.
