DB21085I This instance or install
uses "64" bits and DB2 code release "SQL10051" with level identifier
Informational tokens are "DB2 v10.5.0.1", "special_31160", "IP23526_31160", and
Fix Pack "1".
Product is installed at "/opt/ibm/db2/V10.5".
db2 update db cfg using STRING_UNITS CODEUNITS32
SQL5130N The value specified for the configuration parameter
"string_units" is not in the valid range of "0" to "0".
Right now I'm playing with 10.5 express-c for the fun of it (we are still on 9.7), so I'm unable to open an PMR about it. I'll make a comment in the documentation about it though.
This is the answer I got from the doc team:
The CODEUNITS32 keyword is currently not available, but will be
implemented in a future release of the DB2 product. This limitation will
be reflected in the documentation after the next documentation refresh.
Thanks for pointing that out!
