The EJB Installation Verification Program (IVP) is a simple application
that CICS® installers
can use to verify the CICS EJB environment. It uses a simple client program
that does not require the use of a Web server. The IVP consists of:
- A line-mode client program that runs in UNIX System Services on z/OS®
- A stateless session enterprise bean running on the CICS EJB server
The IVP tests:
- The CICS JVM (including its reusability).
- Optionally, your “real”, enterprise-level, name server. (By default, the
IVP uses the lightweight tnameserv COS Naming Server supplied
with Java.)
- The EJB server's ability to run a simple enterprise bean.
- HFS settings (including file access permissions).
Once configured, the client:
- Performs a JNDI lookup to find the published reference to a specific enterprise
bean in the JNDI namespace
- Creates a new instance of the enterprise bean in CICS
- Calls a remote method on the bean-instance
