    Unanswered: create database collate system V10.5


    I created a database V10.5 under LINUX 11.3 setting collate to "SYSTEM" with the following script:

    create database <DBNAME>
    automatic storage yes
    on /db2/<DB2INSTANCE>/data/<DBNAME>/data dbpath on /db2/<DB2INSTANCE>/data/<DBNAME>/metalog
    using codeset ISO885915
    territory de_DE
    collate using system
    pagesize 16384
    dft_extent_sz 4;

    It worked fine but as I check the configuration of the database (db2 get db cfg) it shows

    Database collating sequence = UNIQUE
    Alternate collating sequence (ALT_COLLATE) =

    I would like to understand why, and which is the difference between both SYSTEM abd UNIQUE

    Thanks a lot in advance
    Best regards

    according the doc : SYSTEM
    This is the default parameter when creating a database. For non-Unicode databases, the collating sequence is based on the database territory.
