Installed CorbaServer and DJAR instances may be managed by CICSPlex® SM through
any of the three interfaces described in
CICSPlex SM support for enterprise beans. All of the
interactive operator services provided through the CICS® CEMT and CEOT transactions are functionally
replicated in CICSPlex SM via the EUI, or through a web browser window. In
either case, the installed CICS objects mapped by CICSPlex SM are:
- EJCOSE—CorbaServer instances
- EJDJAR—CICS-deployed JAR file instances
Additionally, any executable enterprise beans may be listed through these
objects:
- EJCOBEAN—Enterprise JavaBeans directly associated with a CorbaServer
- EJDJBEAN—enterprise beans directly associated with a DJAR
Both of these objects describe an enterprise bean structure: one is keyed
through a CorbaServer name, and the other is keyed through a DJAR id. In
both cases, the only enterprise bean content available for enquiry is the
CorbaServer name, the DJAR name, and the enterprise bean name up to 240 characters
in length. The Enterprise JavaBean specification states that enterprise bean
names may be much longer, but the CICS implementation limits them to 240 bytes.
An additional detail that CICSPlex SM inquiries provide over a standard CICS
inquiry is a count of the available beans in any given DJAR or CorbaServer.
When a new set of enterprise beans are deployed via a DJAR to a particular
CorbaServer, the enterprise bean count can provide an instant confirmation
as to the availability of the enterprise beans in question. The value is incremented
according to the number of enterprise beans accepted through the DJAR installation
process.
Other Enterprise Java™ associated CICS objects that are inquirable
through CPSM are:
- TCPIPS - TCPIPSERVICE instances
- RQMODEL—REQUESTMODEL instances
- LOCTRAN—local transaction instances
- UOWORK—unit of work instances
- UOWLINK—unit-of-work-link (UOWLINK) instances
- PROGRAM—program instances
All of these objects include attributes which have relevance to the management
and execution of enterprise beans.
