| Problem description: | |
Creating an index using UDT columns limits the size of the index
to 16,775,134 data pages per fragment because a data page is
created no matter it is a detach index.
It means index can not grow until "Maximum number of pages per
index fragment" that is 2,147,483,647.
For example the following index was created on a LVARCHAR column
using "create unique index my_index on mytab (col_lvarchar)
using btree in idxdbs1;"
The 'oncheck -pt' of the index shows :
Index my_index fragment partition idxdbs1 in
DBspace idxdbs1
Physical Address 11:40
Creation date 10/24/2023 12:59:26
TBLspace Flags 802 Row Locking
