Set max_strings_size to extended

edited Nov 22, 2017 4:39AM in Database Administration (MOSC) 5 commentsAnswered

Here is using 12.2 database and would like to set the max_string_size to extended.

during the setting . there is a warning

Index "OWNERNAME"."INDEX_NAME" must be dropped because it now exceeds maximum key length.

The index is a single column index on a table. which the column is varchar2(4000 char)

what's the problem on this ?. MAX string size successfully changed to EXTENDED.

Database charset is UTF8

tablespace blocksize is 8K

Howdy, Stranger!
