Step 2: Customize the BS2000/OSD Batch RPC Server Configuration File RPC-CONFIG
Step 4: Customize the BS2000/OSD Batch RPC Server Startup JCL
Verifying the Installation of the BS2000/OSD Batch RPC Server
The SVM file is used at runtime to marshal and unmarshal the RPC data stream. This enables the RPC server to support special COBOL syntax. This server-related information is held in an ISAM file, which needs to be defined and initialized. Each RPC server requires its own SVM file.
Customize S-procedure CREATE-SVM-FILE in
EXP951.JOBS.
| Procedure Parameter | Description | Default |
|---|---|---|
| EXP-LIB | BS2000/OSD Batch RPC Server load library | EXP951.LIB |
| SVM-FILE | SVM file name | SVMFILE |
| SYSOUT-FILE | SYSOUT file name | RPC.SYSOUT.CREASVM |
The SVM file name must correspond to the SVM file specified in the BS2000/OSD Batch RPC Server startup job control. See Step 4: Customize the BS2000/OSD Batch RPC Server Startup JCL.
See also Handling SVM Files in the BS2000/OSD administration documentation.
RPC-CONFIG in EXP951.JOBS contains the RPC server parameters. If the
default settings are used, only the BROKERID
parameter needs to be set up according to your environment. The
BS2000/OSD Batch RPC Server will then run in a default configuration.
Depending on the communication method, the Broker ID has two formats:
ip:port:TCP
| where | ip |
is the address or DNS host name, |
port |
is the port number that EntireX Broker is listening on, and | |
TCP |
is the protocol name |
ETBnnn:SVCmmm:NET
| where | nnn |
is the ID under which EntireX Broker is connected to the Adabas ID table, |
mmm |
is the SVC number under which the Adabas ID table can be accessed, and | |
NET |
is the protocol name |
If the provided parameter file is used, the RPC server will run as a
COBOL server. Besides the RPC service
(RPC/SRV1/CALLNAT), it will register the DEPLOYMENT and
the EXTRACTOR service. This corresponds to the delivered settings in the broker
attribute file on BS2000/OSD and other platforms. The server is configured to
run with a fixed number of 3 worker task replicates. System Management Hub support and
security are turned off.
See also Configuring the RPC Server.

The BS2000/OSD Batch RPC Server requires ADALNK
parameters when a local communication with an EntireX Broker on same machine is
desired (XCOM communication). Set up the IDTNAME
in RPC-ADAPARM in EXP951.JOBS under which the broker
has registered at the Adabas ID table.
| Parameter | Description |
|---|---|
| ADALNK IDTNAME=ADA<xxxxx> | Specifies the ID table name under which EntireX Broker is accessible. |
The job control delivered with BS2000/OSD Batch RPC Server makes use of BS2000/OSD
S-procedures. We strongly recommend you do not modify
START-RPC-SERVER. This procedure is recursively
called to establish the RPC server environment. Modifications should only be
done to the PARAMETER-DECLARATION section as described below. If
all RPC server components are installed under the same BS2000/OSD user ID and
all previous installation steps have been done using the default settings, no
modifications to START-RPC-SERVER are necessary to
run a COBOL server and execute the delivered examples.

| EXX-LIB | EntireX Broker load library. | EXX951.LIB | ||||||
| WAL-MOD | WAL library. | WAL825.MOD | ||||||
| PROGRAM-LIB | Server module library. Additional server module libraries can be
included in the BLSLIB chain. (See the SET UP FILE LINKS section
in the START-RPC-SERVER job control.) There are two sample server
libraries delivered:
|

The BS2000/OSD Batch RPC Server is delivered with libraries that contain COBOL client sample programs, and COBOL and C server sample programs. The sample client and server programs can be used for installation verification. They also correspond to the basic and reliable RPC examples delivered with the EntireX Developer's Kit on other platforms, for example UNIX and Windows.
See Client and Server Examples for BS2000/OSD in the COBOL Wrapper documentation and Server Examples for BS2000/OSD in the C Wrapper documentation.
