Hi Robin
First Thing : Thank you for looking into it and providing valid suggestions.
Made few changes :
1.I have removed distinct in the select query.
2.I already have indexes for both tables for required columns as below.
Code:
--staging
CREATE UNIQUE INDEX schemaname.PK_Customer_Staging
ON schemaname.Customer_Staging(Name ,CUST_ID,ORG_ID)
ALLOW REVERSE SCANS PAGE SPLIT SYMMETRIC
--target
CREATE UNIQUE INDEX schemaname.PK_Customer_Table
ON schemaname.Customer_Table(Name ,CUST_ID,ORG_ID)
ALLOW REVERSE SCANS PAGE SPLIT SYMMETRIC
3.I observed my db2 uses MAX_LOG => 32 and LOGPRIMARY is 12(No way to extend this as its max provided by tool client ) and do get transaction log space error while loading first time since no data exists in target table.
Is there any way to split the logic based on row count and insert data in two parts . Like First 5 Million , then 5=M to Max count .
Or any other approach to load huge 8 Million data . Any help appreciated.

capture-schema
capture-schema(1m) Application Server Utility capture-schema(1m)NAME
capture-schema - stores the database metadata (schema) in a file for use in mapping and execution
SYNOPSIS
capture-schema-dburl url-username name- password password-driver a_jdbc_driver [-schemaname name] [-table tablename]* [-out filename]
Stores the database metadata (schema) in a file. You can also use the Sun Java System Studio IDE to capture the database schema. Run cap-
ture-schema as the same database user that owns the tables, so that the -username and -schemaname options are given the same username.
Additionally, you can grant the database user running the capture-schema command the ANALYZE ANY TABLE privilege.
OPTIONS -dburl JDBC URL expected by the driver for accessing a database.
-username user name for authenticating access to a database.
-password password for accessing the selected database.
-driver JDBC driver classname in your CLASSPATH.
-schemaname name of the user schema being captured. If not specified, the default will capture metadata for all tables from all
the schemas accessible to this user. Specifying this parameter is highly recommended. If more than one schema is
accessible to this user, more than one table with the same name may be captured which will cause problems.
-table name of the table; multiple table names can be specified.
-out output target; defaults to stdout. This parameter corresponds to the schema sub-element of the sun-cmp-mapping ele-
ment in the sun-cmp-mapping_1_1.dtd file.
EXAMPLES
Example 1: Using capture-schema
capture-schema -dburl jdbc:oracle:thin:@sadbuttrue:1521:ora817
-schemaname cantiflas -username CANTIFLAS -password enigma -driver
