RPC data is described by Software AG IDL. See Software AG IDL File. The RPC Server for IBM MQ offers two possibilities to map IDL to MQ messages:
IDL is mapped to XML format using the XML Mapping Editor.
The outcome of this process is an XML mapping file (Designer file with extension xmm).
This resulting XMM file has to be specified by the configuration property entirex.bridge.xmm
.
The RPC Server for IBM MQ uses the predefined mapping of IDL data types to the MQ message buffer. See below.
If your programs use arrays of groups, set the property entirex.bridge.marshalling
to "Natural" or "COBOL".
If your programs do not use arrays of groups, do not set entirex.bridge.marshalling
.
