FORMAT 2 Databases

You can downgrade Version 12 CXX databases set with FORMAT 2 to r11.

During the CONVERT1211, the following actions are taken for each database set to FORMAT 2.

Note: Other than special case test systems, users are not expected to have these conditions.

  1. If the index is set to dynamic extend in cylinders, converts to tracks.
  2. If there are multiple index data sets, removes them with warning message (DB13278W) but RC 0. The index is set to NOT LOADED.
  3. If any data area is set to dynamic extend in cylinders, converts to tracks.
  4. Sets the tables index loaded or not based on every key definition being loaded.
  5. Keeps every key definition in CXX as a normal key losing any other status, such as being created or dropped (not visible to users).
