Parameters

DSSHDR
The 6-byte header that contains information about the data stream structure (DSS).
LL
The length specified as a 2-byte binary integer. This length includes LL and CP.
CP
X'14AC', the 2-byte codepoint of the ACCSECRD reply object.
SECMEC
Specifies the security mechanism or mechanisms supported by the target server. If the target server supports the DDM security mechanism specified by the source DDM server on the ACCSEC command, the value of SECMEC in the ACCSECRD reply object is the same as the value of SECMEC in the ACCSEC command. If the target server does not support the security mechanism specified by the source server, SECMEC contains one or more values that identify the security mechanisms supported by the target server.

Usage

In a successful exchange, the IMS target server confirms the type of security checking requested by the source application program by returning the ACCSECRD reply object with the same value in SECMEC parameter as was submitted in the ACCSEC command.

If an error is detected in processing the ACCSEC command, a SECCHKCD is returned with the ACCSECRD. The SECCHKCD parameter has an implied severity code of ERROR. Before the SECCHK command can be sent to authenticate the connection, the ACCSEC command must be sent again to generate a new set of instance variables on the ACCSECRD.
