DB2 - Problem description

Problem IC64318 Status: Closed

DB2IUPDT MAY RETURN DBI1177W IF A SPECIAL BUILD WAS INSTALLED IN A SEPERATE
INSTALLATION PATH

product:
DB2 FOR LUW / DB2FORLUW / 910 - DB2
Problem description:
If you install a DB2 Special Build (db2setup/db2_install) in a 
different directory than the previous installation then 
db2iupdt may fail with a misleading DBI1177W message: 
 
DBI1177W Updating an instance to a code level that is lower than 
         the current level used by the instance. 
 
This problem is caused by a invalid comparison of the build 
level strings in the instance update scripts (i.e.: sYYMMDD vs. 
special_NNNNN). 
 
Note: If you are going to install a Special Build provided by 
DB2 Technical Support then the warning can be ignored and 
db2iupdt should be run with the "-D" option to overcome the 
problem.
Problem Summary:
Users Affected: ALL USERS ON UNIX PLATFORMS (DOES NOT APPLY TO 
WINDOWS PLATFORM)

Local Fix:
Run "db2iupdt -D" as suggested by the db2iupdt script to skip 
the build level check. 
 
or 
 
Alternativly use the "installFixPack" script to install the 
Special Build in the same path than the previous installation. 
In this case the problem does not occur.
