ZAPS-DDL-ORIGINAL-ERROR tells you the first error that was detected in the
current error situation. It comes from the lowest service layer in the OSI/AS
subsystem at which an error occurred. This structure may help you diagnose errors at
higher layers.
DEFINITION ZAPS-DDL-ORIGINAL-ERROR.
02 ZDEVICE-NAME TYPE ZAPS-DDL-FILENAME.
02 ZERROR TYPE ZAPS-DDL-CURRENT-ERROR.
END
ZDEVICE-NAME is a fully qualified device name (including the subdevice, if
applicable) of the entity that originally detected the error. If not applicable, the device
name is blank.
ZERROR contains details of the error originally detected, and identifies the service
that detected it.
ZAPS-DDL-PRES-CNTXT-LIST is the presentation context definition list chosen by
the application. The list consists of up to 16 presentation context definitions, each of
which is identified by a presentation context identifier (PCID). Each presentation
context definition contains a PCID, an abstract syntax name, and one to three transfer
syntax names. The PCID must be an odd integer in the range 1 through 9999. The
called application decides which of the transfer syntax names is to be used for each
presentation context, and returns this information in the presentation context
definition result list.
If you are using the OSI/AS implementation of ACSE, you must not propose a
presentation context for ACSE itself in the connect request; OSI/AS will supply it in
the presentation context definition list. For ACSE, you can propose 15 other
presentation contexts.
The presentation context definition list is set in a presentation or ACSE connect request
through a call to APS_ASSOC_CONNECTREQ_. It can be retrieved in a presentation
or ACSE connect indication with a call to APS_ASSOC_GETPARAM_.
