Key less Technique
To more previously staged partitioning to next corresponding stage with same key column values.
ENTIRE
The right answer is that with SQL Server we don't really need a Sequence Generator or State File or a database sequence, we just need to add to the table the IDENTITY column which will auto increment for every record inserted. And to use that with the SCD stage just let the Surrogate Key option blank. DataStage Surrogate key generator state file. Technote (FAQ) Question. The state file is a key source for the surrogate key generator stage, the state file persists data that contains the next value and properties for creation of keys between job runs utilising this key source. It is a flat file in the file system.
Can only be used in lookup stage with reference link when it is “normal lookup”
In Entire what ever the records that are processing on N1, the same set of records are processed on the rest of the node.
RANDOM - Default / Auto
Round Robin
Generates the next number with sequence
Note :-
All the Generating stages gives the best performance when they are associated with Round Robin.
Generating Stages
column generator , Row generator, Surrogate Key stage
RANGE
It is an Expensive partitioning Technique than Mod and Hash . This technique needs data pre processing.
Open source software license key generator no survey. Note :-
Stage :- Write Range Map (Development/ Debug stage) To create the range if we want to use Range partitioning

Brief on Surrogate key in DataStage
Surrogate key
Output
If we don’t take surrogate key
Serial key generator for any software. it maintains a new column active flag(indicate current address)
o/p:
Ex:
Surrogate Key Generator In Datastage 1
After data;(source)
Before Data(Target)
Output
Before data(Target)
![]()
After Data: (Source)
Output
Active Tag :- (A.F)
New records will maintain flag ‘Y’
Old records ‘N’
Tables will data maintain effective start data and effective end data
If data is not displayed, then we get a new column record version , unique id
Record version, unique id
SCD - Type
Table 1
Create table SRC (SNO number (3), S name Varchar 2 (25)); Create the table and reject values
Table 2
Create table CIM (SNO number (2), S name Varchar 3 Sname varchar2 (25)); Just create the table only
5 steps for SCD – Type 1
S1:- Select output link as Fact link
S2: Map the lookup key SNO
S3: Source type = flat file

= Source Name = (Empty file Name)
S4 : identifying the purpose of each field
S5: Map required fields to fact table
Load properties
S1: Set Data set properties
S2: Set oracle properties
Table name = dim 1
Write method = upset (update and insert)
