General Parameters 

Side information files can contain the following platform-independent parameters:

To reduce configuration work, you can define default entries under DEST=COMMON_PART. All entries that you define under this “destination” are default values for the remaining side info entries.

If an entry is missing for a destination, the default entry is assumed, provided a default entry has been defined under DEST=COMMON_PART.

General parameters of the sideinfo table:

Parameter	Meaning
DEST	Symbolic name of the target system
LU	R/3 application host SNA: Logical unit (LU) of the partner
TP	Transaction program of the partner
PROTOCOL	Protocol type C, I or E (see specific Side Info Parameters)
GWHOST	Host, on which the SAP Gateway is running
GWSERV	Gateway service
MODE_NAME	SNA mode name
CPIC_TRACE	Trace switch: 0, 1, 2 or 3

If you are using SAP’s SNC interface:

SNC*	Name of the SNC partner
SNC_MODE	SNC switch: ON   (Default setting when using SNC) OFF (deactivates SNC, overrides SNC and SNC_LIB)
SNC_LIB *	Name of the SNC library

(* Optional parameters, see also Environment Variables)

Please note the following points:

·        No side info: SAP_CMINIT3 provides all the connection parameters

·        Depending on application, not all the entries have to be available:
You do not have to define the parameters GWHOST and GWSERV, if the call SAP_CMINT provides them.

·        You can access the side info file in the CPI-C program and possibly in the SAP Gateway. It can be a matter of various files, depending on the call directory and the environment variable SIDE_INFO.
