This document describes how to set up the RPC server front-end for an RPC
batch server environment under BS2000/OSD with the print file/work file server
NATPWSV2
.
The following topic is covered below:
For the generation of the Natural RPC batch server, the front-end 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 front-end 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.
RPCSTUB2 BS2STUB PARMOD031,PROGMOD=ANY,UNRES=*DBLOPT ADDON NAME=RPCSERV, Name of reentrant part (load pool) - . . . ADDON definition for Natural Buffer Pool . ADDON definition for Natural Editor Pool . ADDON definition for Natural Swap Pool . ADDON NAME = PWK#POOL, Name of print file/work file control pool - TYPE=PWK, Pool type - SIZE=1MB, Pool size in MB - STAT=LOCAL, Pool status is local - SCOP=GLOBAL, Scope is global - POSI=ABOVE, Pool position is above - PFIX=YES, Pool address is fixed - ACCS=WRITE No pool protection 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 front-end part of the Natural RPC batch server:
/EXEC $TSOSLNK PROG SERVER,FILENAM=BATCH.SERVER,LOADPT=X'1000000',XREF=YES TRAITS RMODE=ANY,AMODE=31 INCLUDE NATSFED2,NATvrs.MOD Must be bound as first module INCLUDE RPCSFE,NATvrs.MOD RPC front-end stub INCLUDE SERVFRNT,USERLIB Front-end part of Natural batch driver INCLUDE SERVRENT,USERLIB Reentrant part of Natural batch driver INCLUDE RPCSTUB2,USERLIB BS2STUB (see above) INCLUDE SWPRMSRV,USERLIB Swap pool parameter module INCLUDE NATPRMSV,USERLIB Natural parameter module INCLUDE ADAUSER,ADAvrs.MOD INCLUDE SSFB2C,ADAvrs.MOD BIND
where:
vrs |
stands for the current version of Natural for Mainframes or Adabas for Mainframes and |
USERLIB |
stands for the user-specific library. |
For information on how to generate the swap pool parameter module, refer to the section Defining the Natural Swap Pool, Keyword Parameters of Macro NTSWPRM.
Example of linking the reentrant part of the Natural RPC batch server:
/EXEC $TSOSLNK MOD RPCSERV,XREF=Y,MAP=Y,XDSEC=Y,SORT=YES TRAITS RMODE=ANY,AMODE=ANY LINK-SYMBOLS *NOESD INCLUDE NATINV,NATvrs.MOD Must be bound as first module INCLUDE NATURAL,NATvrs.MOD Natural nucleus COMMENT NATWKFB2,NATvrs.MOD Is replaced by INCLUDE NATFSTB2,NATvrs.MOD print file/work file server stub . All other . moduls INCLUDE NATLAST,,NATvrs.MOD BIND
where vrs stands for the current version of Natural for Mainframes.
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, AUTORPC=ON,TRYALT=OFF ), 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 stands for the current version of Natural for Mainframes, Adabas for Mainframes or EntireX Communicator.
