Summary of Conversion Steps

To convert to Dynamic Server 10.0, complete the following conversion steps. The subsections that appear below these summary steps provide more information about each step.

To convert to Dynamic Server 10.0
  1. If necessary, perform Enterprise Replication preconversion tasks. For more information, see Migrating to Dynamic Server 10.0 with Enterprise Replication.
  2. Check and configure available space.
  3. Save copies of the current configuration files.
  4. Close all transactions and shut down the source database server.
  5. Check for any open transactions.
  6. Verify the integrity of the data.
  7. Verify the database server mode.
  8. If necessary, disable High-Availability Data Replication.
  9. Make a final backup of the source database server.
  10. Run ontape -a after the backup is complete.
  11. Verify that the source database server is offline.
  12. On UNIX or Linux, modify kernel parameters.
  13. Install Dynamic Server 10.0, according to instructions in your IBM Informix: Installation Guide. Be sure not to install the new database server over the old database server.
  14. Monitor the message log, online.log, during the conversion for any error messages.
  15. Set environment variables.

    Note:
    Before you start the 10.0 database server, you must set the environment variable DBONPLOAD to the name of the pload database if the name is not onpload, the default name.
  16. Customize configuration files.
  17. Add any Communications Support Modules.
  18. Install and configure any DataBlade modules.
  19. Switch to user informix and initialize Dynamic Server 10.0 to trigger the conversion.
  20. Monitor the conversion complete status.
  21. Upgrade the High-Performance Loader onpload database for the current version of Dynamic Server if necessary, for example if onpload failed during server conversion.
  22. For ON–Bar, rename or edit the sm_versions.std file.
  23. Update statistics.
  24. Verify the integrity of the data.
  25. Make an initial backup of Dynamic Server 10.0.
  26. Tune Dynamic Server 10.0 for performance.
  27. If necessary, perform Enterprise Replication conversion tasks. For more information, see Converting to Dynamic Server 10.0 with Enterprise Replication.
  28. If necessary, enable HDR.

Repeat this procedure for each instance of Dynamic Server 10.0 that you plan to run on the computer.

Warning:
If a serious error occurs during the conversion, it might be necessary to return to the previous version, restore from a backup, and then correct the problem prior to restarting the conversion tasks.
