Advanced communication interface. ACI-based programming is the base technology of EntireX. It uses a traditional Application Programming Interface (API) approach for conducting client/server and peer-to-peer dialog between distributed processes.
This document describes the EntireX Broker ACI from the perspective of the programming language RPG and covers the following topics:
Calls to EntireX Broker use the following arguments:
The ACI control block is the first argument.
The send buffer is the second argument.
The receive buffer is the third argument.
The error text buffer is the last argument. It can provide a short
text of the error code, if desired. Sufficient buffer length must be supplied
to allow the standard 40-byte-long message to be returned by EntireX Broker.
For ACI version 9 and above, the error text buffer can be greater than 40 bytes as
specified in the ACI field ERRTEXT-LENGTH.
The send buffer and the receive buffer must always be provided. If they are not required by the selected EntireX Broker function, you can define them as PIC X(1) fields.
The API is called with a statement as follows:
C...CALLB(D) 'broker' C...PARM ETBCB C...PARM G_SEND_BUFF C...PARM G_RECV_BUFF C...PARM ERROR_TEXT
The following table shows the Broker fields in the order of the physical layout of the Broker ACI control block and provides a brief description of each field. See the actual copybook for RPG below in Broker ACI Control Block Copybook.

When you begin to write your first Broker ACI program in RPG, you can use these examples as a model for your own implementation:
client: BCOCRPG
server: BCOSRPG
Depending on your platform for RPG, you will find the files with the examples, copybooks, etc. at the following locations:

Notes:
On the IBM i system, the broker stub is implemented as an object of
type *SRVPGM (Service Program). This object type has the advantage that its
program code can be shared by several programs. It exists as an object on its
own and can therefore be easily replaced without rebinding the user's
application, when a newer version becomes available.
The service program EXA supplied by Software AG contains all the functions necessary for controlling and communicating with the remote broker. To create an executable Broker application on IBM i, you need to develop, in any ILE-enabled programming language, at least one main module to which the EXA service program is bound.
For compilation use the IBM i command
CRTRPGMOD
For binding use IBM i command CRTPGM with
the option:
...BNDSRVPGM(*LIBL/EXA)...
Example:
The following steps show how to create a server application using the program BCOSRPG. See ACI Examples and Copybooks.
The library EXX must be located in the *LIBL list.
To set the library list, you can use the IBM i command:
CHGCURLIB CURLIB(EXX)
To compile BCOSRPG, use the command
CRTRPGMOD with the following options:
MODULE(BCOSRPG) SRCFILE(*CURLIB/EXASRC) OUTPUT(*PRINT)
Or, use the sample procedure CRT_RPGMOD.
If the program has been successfully compiled, the module BCOSRPG will be created.
To produce an executable program, bind the user program BCOSRPG to the service program EXA supplied by Software AG.
CRTPGM PGM(EXX/BCOSRPG) MODULE(*PGM) ENTMOD(*PGM) BNDSRVPGM(EXX/EXA) BNDDIR(*NONE) OPTION(*GEN *WARN *DUPVAR) DETAIL(*EXTENDED)
Or, use the sample program EXABNDPGM.
