Pre-conversion tasks for Db2 pureScale environments

Before you convert your environment to Db2 pureScale environment, review the following restrictions to identify anything that can affect the conversion. You must address any issues before converting to have a successful conversion.

Procedure

Prepare for converting your environment to a Db2 pureScale environment by performing the following tasks:

  1. Verify that your databases are ready for converting to a Db2 pureScale environment.
    Verifying that your databases are ready for conversion identifies any problems before the actual conversion. You must resolve any problems found before you proceed with the conversion. Refer to Verifying that your databases are ready for a Db2 pureScale environment.
  2. Set up a IBM Spectrum Scale file system.
    You must ensure that all data and logs are on a Db2 cluster file system before you convert. See Setting up an IBM Spectrum Scale file system for a Db2 pureScale environment.
  3. Convert table spaces.
    You must ensure that you have automatic table spaces before you convert. Refer to Converting table spaces for a Db2 pureScale environment.
  4. Back up your databases.
    You can restore them in the original pre-converted system if needed. For details, see Backing up databases when converting to a Db2 pureScale environment.
  5. Back up your server configuration and diagnostic information.
    Backing up the configuration and diagnostic information gives you a record of your current configuration that you can compare with the configuration after the conversion. You can also use this information to create new instances or databases using the same configuration that you had before conversion. For more information, refer to Back up DB2® server configuration and diagnostic information.
  6. If the error capture level of the diagnostic log files is set to 2 or less, set the error capture level to level 3 or higher.
    In this release, all significant conversion events are logged in the diagnostic log when the diaglevel database manager configuration parameter is set to 3 (default value) or higher.

    For details, see Setting the error capture level of the diagnostic log files.

  7. Take the Db2 server offline before conversion.
    Refer to Taking a DB2 server offline for upgrade or for enabling a Db2 pureScale environment.
