The custom table spaces must exist prior to the execution of database transfer.

The page size of table spaces used by WebSphere Portal must be 8192 bytes.

If custom table spaces are assigned, each must be assigned explicitly. The default table spaces can be used to contain database objects; however the name of the default table space must be specified in the corresponding mapping files. This applies to all database domains that are transferred in a single database transfer.

To configure custom table space assignments:

  1. Install DB2

  2. Create users

  3. Create remote databases

      community.COMP_INST.tablespace=IN COMM8KSPACE

    Repeat this step for each domain that you are transferring.

  7. Save and close

  8. From a command prompt, when starting the database transfer, specify the option...
