Hi Dharani,
Follow the below example.
*1. Create a Distribute file.*
jsh R10 ~ -->CREATE-FILE DUGGI TYPE=DISTRIB
[ 417 ] File DUGGI]D created , type = J4
[ 417 ] File DUGGI created , type = DISTRIB
*2. Assign the partion algoritham for Distribution file. Distribution
alogoritham is by defalut SYSTEM algoritham or USER defined algoritham. In
this example I used the USER defined algoritham to specify allocation 4
partition files*
+++++++++++++++++++++++++++++++++++++++++++++++++++++
SUBROUTINE DISTALGO(First, Key, PartNo)
EQU Otherwise TO 1
Result = MOD(DATE():TIME(),3)
BEGIN CASE
CASE Result = 1
PartNo = 1
CASE Result = 2
PartNo = 2
CASE Result = 3
PartNo = 3
CASE Otherwise
PartNo = 4
END CASE
RETURN
+++++++++++++++++++++++++++++++++++++++++++++++++++++++
Compile and catalog the above partition algorithm subroutine and attach it
to Main file.
jsh R10 ~ -->CREATE-DISTRIB -pUSER,DISTALGO DUGGI
*3. Create part files to Main file.*
jsh R10 ~ -->CREATE.FILE DATA DUGGI.1 TYPE=J4 2,100
[ 417 ] File DUGGI.1 created , type = J4
jsh R10 ~ -->CREATE.FILE DATA DUGGI.2 TYPE=J4 2,100
[ 417 ] File DUGGI.2 created , type = J4
jsh R10 ~ -->CREATE.FILE DATA DUGGI.3 TYPE=J4 2,100
[ 417 ] File DUGGI.3 created , type = J4
jsh R10 ~ -->CREATE.FILE DATA DUGGI.4 TYPE=J4 2,100
[ 417 ] File DUGGI.4 created , type = J4
*4. Add 4 part files to DUGGI (Main distribution file)*
jsh R10 ~ -->CREATE-DISTRIB -a DUGGI 1 DUGGI.1
Part file 'DUGGI.1', Part number 1 added
jsh R10 ~ -->CREATE-DISTRIB -a DUGGI 2 DUGGI.2
Part file 'DUGGI.2', Part number 2 added
jsh R10 ~ -->CREATE-DISTRIB -a DUGGI 3 DUGGI.3
Part file 'DUGGI.3', Part number 3 added
jsh R10 ~ -->CREATE-DISTRIB -a DUGGI 4 DUGGI.4
Part file 'DUGGI.4', Part number 4 added
*5. List all the part files using *
jsh R10 ~ -->LIST-DISTRIB DUGGI
Partitioning Algorithm is USER Subroutine 'DISTALGO'
Part file 'DUGGI.1', part number 1
Part file 'DUGGI.2', part number 2
Part file 'DUGGI.3', part number 3
Part file 'DUGGI.4', part number 4
jsh R10 ~ -->
After this you can insert any number of records in DUGGI file, those
records hopefully distributed among all the part files.
Thanks and Regards,
Duggineni Haribabu.
