I've used already a similar procedure (involving db2move) to transfer a DB2 database from Windows to AIX and vice-versa.
DB2’s native backup utility creates a backup image that is not portable from W2K to AIX or back. This document presents the procedures required for moving any DB2 database from one platform to the other.
For purposes of example, this document assumes that the database to be ported from W2K (source platform) to AIX (target platform) is MYDB.
Run the db2look command for MYDB database to generate the DDL for the MYDB database.
db2look -d mydb -e –l –x -o mydb_create.sql
Create a directory in which to store the logical backup of the source database MYDB.
Change to the new directory, and create the logical backup using the db2move utility
db2move mydb export
Transfer the backup of the database and DDL script from Source to Destination. Transfer mydb_create.sql in ASCII mode, and all backup*.ixf files in binary mode.
The following steps are to be performed on the target platform.
Split the mydb_create.sql script into two scripts. The first is named mydb_tables.sql, and should contain all alias, table, and view creation commands. The second script is to be named mydb_ri.sql, and picks up where the first stopped, including check and foreign key constraints and grants. Make sure that both scripts have a CONNECT command at the top, and COMMIT, CONNECT RESET, and TERMINATE commands at the end.
Edit the mydb_tables.sql and ensure that any user tablespaces use only relative path names. If absolute path names are used, the database cannot be restored multiple times on the same system without a REDIRECTED RESTORE.
Create an empty MYDB database.
create db mydb
Run the mydb_tables.sql script to create aliases, tables, and views.
db2 –tvf mydb_tables.sql > mydb_tables.out
Review mydb_tables.out for errors. An easy method of doing this is to run the following command.
grep SQL0 mydb_tables.out|grep –v SQL0403W|grep –v SQL0598W|more
Import the data to the tables (the INSERT option can be used instead of REPLACE, but REPLACE is rerunnable).
db2move mydb load -lo replace
Run the mydb_ri.sql script to create referential integrity constraints, etc.
db2 –tvf mydb_ri.sql > mydb_ri.out
Review mydb_ri.out for errors. An easy method of doing this is to run the following command.
grep SQL0 mydb_ri.out|grep –v SQL0403W|grep –v SQL0598W|more
Verify that the source and target databases are identical.
