db2move and db2look utilities as alternative backup methods


Sometimes backups may not be transportable to another operating system, or you may have to copy only a subset of a database, or perhaps just a schema. Since the backup command does not support these operations, we can still use db2move and db2look for alternate backups.

db2look is useful with extracting DDL, or data definition language, so we can recreate database objects, if need be. db2move will take care of data movement.

Getting ready

Allow for sufficient space and time for data extraction. We suggest you have a separate drive or filesystem for these, especially if you intend to have huge tables copied this way.

How to do it...

  1. Choose a proper directory:

    [db2inst1@nodedb21 ~]$ cd /xchng/exports/pos/
    
  2. Check if enough space is available:

    [db2inst1@nodedb21 pos]$ df .
    Filesystem            Size  Used Avail Use% Mounted on
    /dev/sdb1             459G   64G  372G  15% /xchng
    
  3. Do the export:

    In this case, we chose to export all the POS schema...
