This document describes how to set up the RPC server front-end for an
RPC batch server environment under BS2000 with the print file/work file server
NATPWSV2.
For the generation of the Natural RPC batch server, the
non-reentrant part of the Natural batch driver (macro NAMBS2) has
to be assembled with the new keyword parameter SERVER=YES.
Example:
SERVFRNT NAMBS2 CODE=FRONT, -
APPLNAM=NATSERV, -
NUCNAME=RPCSERV, -
DYNPAR=SYSDTA, For server parameters -
SERVER=YES, Generate RPC server -
ROLLTSZ=384, Roll thread size in KB -
. All other parameter definitions as for
. the generation of the non-reentrant part
. of the Natural batch driver
END
For the generation of the reentrant part of the Natural RPC batch server, you can use the same keyword parameter definitions as for the generation of the Natural batch driver.
For the generation of the module BS2STUB (front-end part of the RPC
batch server), you have to define the necessary common memory pools. If you
intend to use the print file/work file server
NATPWSV2, define a
print file/work file control pool and replace the module NATWKFB2
with the module NATFSTB2 in the Natural reentrant part.

ADDEND
The Natural RPC batch server stores the different client context in user threads. These user threads are managed either in the swap pool or in the Natural roll file. Hence, a Natural roll file and a Natural swap pool is required.
For the processing of print files and work files, a print file/work file server has to be generated (see Print File/Work File Server NATPWSV2), using the new type "PWK".
Data interchange between RPC batch server and print file/work file server takes place in a common memory pool (print file/work file control pool), using the new type "PWK".
Communication between RPC batch server (module
NATFSTB2) and print file/work file server (module
NATPWSV2) is accomplished by way of P1 forward
eventing. If you intend to work with the print file/work file server, then the
module NATWKFB2 has to be replaced by the module
NATFSTB2 in the link job for the reentrant part.
Example of linking the environment-dependent nucleus for the RPC batch server:
/START-PROGRAM $BINDER START-LLM-CREATION INTERNAL-NAME=SERVER, - SLICE-DEFINITION=*BY-ATTRIBUTES(RESIDENCY-MODE=*YES) INCLUDE-MODULES NATSFED2,LIB=(NATvrs.MOD) Must be bound as first module INCLUDE-MODULES RPCSFE,LIB=(NATvrs.MOD) RPC front-end stub INCLUDE-MODULES SERVFRNT,LIB=(user-lib) Non-reentrant part of Natural batch INCLUDE-MODULES SERVRENT,LIB=(user-lib) Reentrant part of Natural batch INCLUDE-MODULES RPCSTUB2,LIB=(user-lib) BS2STUB (see previous example) INCLUDE-MODULES SWPRMSRV,LIB=(user-lib) Swap pool parameter module INCLUDE-MODULES NATPRMSV,LIB=(user-lib) Natural parameter module INCLUDE-MODULES ADAUSER,LIB=(ADAvrs.MOD) INCLUDE-MODULES SSFB2C,LIB=(ADAvrs.MOD) MODIFY-SYMBOL-ATTRIBUTES ADD-MODE=*31,RES-MODE=*ANY,READ-ONLY=*NO MODIFY-SYMBOL-VISIBILITY - SYMBOL-NAME = *ALL, - SYMBOL-TYPE = *DEFINITIONS, - VISIBLE = *NO(KEEP-RESOLUTION=*YES) SAVE-LLM LIB=NATURAL.USER.MOD,LOAD-ADDR=X'10000000',ELEMENT=BATCH.SERVER END
where:
vrs |
is the relevant product version of Natural for Mainframes or Adabas for Mainframes and |
user-lib |
is the user library. |

Example of parameters for the Natural batch server:
AUTO=ON, STACK=(LOGON DFSERVER), RPC=( SERVER=ON, SRVNODE='10.20.91.202:3860:TCP',SRVNAME=DFSRV1, RPCSIZE=128,MAXBUFF=30, TRACE=2 ), RCA=BROKER,RCALIAS=(BROKER,BKIMBTIA), MADIO=0,MAXCL=0,MT=0,MENU=OFF, PRINT=((10),AM=STD),WORK=((1-10),AM=STD)
Example of parameters for the Natural RPC server client:
STACK=(LOGON DFCLIENT), RPC=( DFS=(DFSRV1,BKR043,,,NOSERVDIR), RPCSIZE=128,MAXBUFF=30 ), RCA=BROKER,RCALIAS=(BROKER,BKIMBTIA), MADIO=0,MAXCL=0,MT=0,ETID=' '
The Natural RPC batch server requires the file named P10 for the
output of server messages. If the print file/work file server is used, this
file has to be defined using the FILE instruction in the job
control for the print file/work file server, unless it is defined in the job
control of the Natural RPC batch server.
Example of a start job:
/.SERVER LOGON /SYSFILE SYSOUT=SERVER.OUT /SYSFILE SYSLST=SERVER.LIST /FILE NATvrs.EDIT.WORKFILE,LINK=CMEDIT /FILE NATvrs.SERVER.ROLLFILE,LINK=PAMNAT,SHARUPD=YES /FILE SERVER.MSG,LINK=P10 Is required for the server messages /FILE ADAvrs.MOD,LINK=DDLIB /FILE ADAPARM,LINK=DDLNKPAR /FILE EXXvrs.LIB,LINK=BLSLIB01 Broker /FILE EXXvrs.LIB,LINK=ETBLIB Load library /SYSFILE SYSDTA=SERVERPARMS /EXEC BATCH.SERVER /LOGOFF N
where vrs represents the relevant product version of Natural for Mainframes, Adabas for Mainframes or EntireX Communicator.
