ICU sort table changes
A change in IBM® i 7.2 requires newly created indexes to use ICU sort tables that are version 3.4 or greater. This requirement affects indexes that are created on 7.2 only. Indexes that were created before 7.2 do not need to be re-created.
An attempt to try to create an index with an unsupported ICU sort table on 7.2 results in a CPD3264 diagnostic message with a reason code of 2 being signaled. SQL created indexes also see an SQ20268 diagnostic message with a reason code of 5.
