The following steps require system modifications to your IMS TM environment.
Create the APPLCTN
table definitions for MPP, BMP and
NTRD according to the following examples:
Example for MPP:
APPLCTN PSB=NIIvrsFR,PGMTYPE=TP TRANSACT CODE=NATvrs,MODE=SNGL,SPA=512, * MSGTYPE=(SNLGSEG,RESPONSE,4)
Example for BMP (message-driven or specific for Natural Advanced Facilities):
APPLCTN PSB=NIIvrsBM,PGMTYPE=BATCH TRANSACT CODE=NATvrsBM,MODE=SNGL, * MSGTYPE=(SNLGSEG,RESPONSE,4)
This APPLCTN
definition is required if you use
the CMGETMSG
feature.
Example for BMP (without message queue processing):
APPLCTN PSB=NIIvrsBM,PGMTYPE=BATCH
Example for NTRD:
APPLCTN PSP=NIIvrsOB,PGMTYPE=TP TRANSACT CODE=NATvrsOB,MODE=SNGL, * MSGTYPE=(MULTSEG,NONRESPONSE,4)
Example for SFE:
APPLCTN PSB=NIIvrsAD,PGMTYPE=TP,SCHDTYP=PARALLEL TRANSACT CODE=NATvrsAD,MODE=SNGL, * MSGTYPE=(SNGLSEG,NONRESPONSE,4)
Create the PSB for MPP according to the following example for conversational Natural:
PCB TYPE=TP,MODIFY=YES PCB TYPE=TP,MODIFY=YES PCB TYPE=TP,MODIFY=YES SENSEG NAME=COURSE SENSEG NAME=PREREQ,PARENT=COURSE SENSEG NAME=OFFERING,PARENT=COURSE SENSEG NAME=TEACHER,PARENT=OFFERING SENSEG NAME=STUDENT,PARENT=OFFERING PSBGEN PSBNAME=NIIvrsFR,LANG=ASSEM,MAXQ=3,IOASIZE=132
At least one modifiable TP-PCB must be defined for default use
of hardcopy, sending messages and transaction switching. The value of the
WRKPCBS
keyword subparameter (NTIMSPT
macro in the Natural parameter
module) in the current environment table must be less than or equal to the
number of PCBs minus 1 to avoid a Natural initialization error.
Create the PSB for BMP according to the following example:
PCB TYPE=TP,MODIFY=YES PCB TYPE=TP,MODIFY=YES SENSEG NAME=COURSE SENSEG NAME=PREREQ,PARENT=COURSE SENSEG NAME=OFFERING,PARENT=COURSE SENSEG NAME=TEACHER,PARENT=OFFERING SENSEG NAME=STUDENT,PARENT=OFFERING PSBGEN PSBNAME=NIIvrsBM,LANG=ASSEM,MAXQ=3,IOASIZE=132
At least one modifiable TP-PCB must be defined for default use
of hardcopy and sending messages. The value of the
WRKPCBS
keyword subparameter in the current environment
table must be less than or equal to the number of PCBs minus 1 to avoid a
Natural initialization error.
After creating the required APPLCTN
s for the BMP
and MPP environments, generate the PSB, DBD and ACB.
After generating the ACB, activate the new definitions by issuing the following commands :
/MODIFY PREP ACBLIB /MODIFY COMMIT
(Job I200, Steps 2500, 2504)
Create the BMP region (Step 2500) according to the
BMPJOB
sample member.
Create the MPP region (Step 2504) according to the
MPPJOB
sample member.
Update the PRELOAD
list by using a
PRELOAD
member DFSMPL xx
with the names of the following modules:
the nucleus,
the interface module,
the front-end, and
the Adabas link module.
NATvrsSH,NIIvrsIF,NIIvrsFR,ADALNI
NATvrsSH,NIIvrsIF,NIIvrsBM,ADALNK
If alias names are used for any members in the
PRELOAD
list, these names should be added to the
PRELOAD
list as well. Failure to do so leads to performance
degradation.
The region size must be large enough to hold the nucleus, the interface module, the front-end, the Natural thread and about 20 KB of working storage below the line.
Include the load libraries used by the Natural IMS TM Interface.
Include the DD statement for the roll file created in Step 1: Allocate and Format the Roll Files:
//ROLLFn DD DSN=....DISP=SHR
where n
is a value
from 1 - 5.
Include the DD statement for NATRJE
:
//NIIRJEDD DD SYSOUT=(X,INTRDR)
In the JCL of the MPP region, add the SYSTPCD
DD
statement if the Natural Development Server or Natural Web I/O Interface server
is used. See IBM's z/OS V1Rx.0 Communications Server IP Configuration
Guide, Chapter 1.5.2, Configuring TCPIP.DATA.
You can verify the successful installation of the Natural IMS TM Interface by following the instructions in this section.
