Preparing for Database 15.x Upgrades

SAP Sybase IQ 16.0 SP03 includes changes to the system tables and database schema. If you are migrating a SAP Sybase IQ 15.x database, objects no longer supported by SAP Sybase IQ 16.0 must be removed or modified.

Note: All steps are specific to customers who are upgrading from SAP Sybase IQ 15.x. Customers upgrading from SAP Sybase IQ 16.0 or later can skip these steps.
  1. Disconnect all users from the 15.x server.
  2. Drop all JOIN and all LD indexes from the 15.x database.
  3. Update DATE columns that contain a time portion.
    There is a known issue that affects any partition defined on a DATE column that contains a time portion:
    • Use ALTER TABLE MERGE to combine the partition with the next partition.
    • Use ALTER TABLE SPLIT to divide the resulting partition into a definition with the same criteria, but no time portion.
  4. Drop and re-create all SAP Sybase IQ 15.2 TEXT indexes that have not already been dropped and re-created as part of a version 15.2 ESD upgrade.

    TEXT indexes created in SAP Sybase IQ 15.2 are incompatible with later versions of SAP Sybase IQ.

  5. Shut down the SAP Sybase IQ 15.x server or multiplex.
    If the server stops responding during shutdown, do not proceed to the next step. Restart the database and shut it down again. Proceed to the next task only on a clean shutdown.
