OTMA descriptors

OTMA provides two types of descriptors: an OTMA client descriptor and an OTMA destination descriptor.

The OTMA client descriptor specifies certain characteristics of an OTMA client, such as its DFSYDRU0 exit routine, its send-then-commit message time out values, or its message flood threshold value.

The OTMA destination descriptor defines destination attributes for:

• OTMA ALTPCB messages that are sent to IMS™ Connect for delivery to a remote IMS system by way of a TCP/IP connection with another IMS Connect instance.
• OTMA ALTPCB output sent to either IMS Connect or non-OTMA destinations such as an SNA terminal or printer.
• Callout requests from IMS applications programs that are sent to IMS Connect and that are ultimately destined for any of the following:
  • An enterprise Java™ bean (EJB) or message-driven bean (MDB) running under a web application server, such as WebSphere® Application Server.
  • A Web service.
  • A user-written IMS Connect client.

Both OTMA client descriptors and OTMA destination descriptors are specified as entries in the DFSYDTx PROCLIB member.

OTMA destination descriptors can also be created and updated online by using the following type-2 IMS commands:

• CREATE OTMADESC
• DELETE OTMADESC
• QUERY OTMADESC
• UPDATE OTMADESC
