Answer Posted / karthikeyan@ibm
In General, system will have standard PROC(DSNUPROC) to
load the Table.Three symbolic parameter needs to be passed.
But only one parameter is mandatory SYSTEM=DB2T(subsystem).
Let me explain the Proc. The Proc contains a step with
DSNUTILB as program to load the table. In Parms, pass the
DB2 susbsystem. In SYSREC ddname points to the dataset that
contains the records to be load.SYSIN ddname points to the
control card that is used to load the table.Control card
contains information like tablename to be loaded, Position
of the column and other options like LOAD with REPLACE or
Load with RESUME, ENFORCE YES OR NO and LOG Yes OR NO.
When you want to specify REPLACE option, all the records or
rows in the table are deleted before loading and RESUME
option will retain the old records or rows in the table.
The tablespace will put in COPY PENDING status when you
load the table with Option LOG NO.
//DSNUPROC EXEC PGM=DSNUTILB,REGION=6144K,PARM='DB2'
//SYSREC DD DSN=&LOADdataset,DISP=OLD
//SYSIN DD DSN=&Controldataset,DISP=OLD
