DB2 FOR LUW / DB2FORLUW / B10 - DB2

Here is an example problem reproducible scenario. 
 
1.  Install V105FP4 
    * This will by default create ESE instance named "DB2" 
 
2.  db2icrt -s wse newdb2 -u:db2admin,insT4Win 
 
3.  db2icrt -s wse newdb2y -u:db2admin,insT4Win 
 
4.  db2ilist will display three instances as below: 
    DB2 
    DB2NEW 
    DB2NEWY 
 
5.  db2set -all will show below 
    C:\Program Files\IBM\SQLLIB\BIN>db2set -all 
    [e] DB2PATH=C:\Program Files\IBM\SQLLIB 
    [i] DB2INSTOWNER=VMINSTWIN14 
    [i] DB2PORTRANGE=60000:60005 
    [i] DB2INSTPROF=C:\PROGRAMDATA\IBM\DB2\DB2COPY1 
    [i] DB2COMM=TCPIP 
    [g] DB2_EXTSECURITY=YES 
    [g] DB2_COMMON_APP_DATA_PATH=C:\ProgramData 
    [g] DB2SYSTEM=VMINSTWIN14 
    [g] DB2PATH=C:\Program Files\IBM\SQLLIB 
    [g] DB2INSTDEF=DB2 
    [g] DB2ADMINSERVER=DB2DAS00 
 
6.  db2stop 
 
7.  db2idrop DB2 (drop "DB2" instance) 
    * We will get a message that no default instance has been 
set. 
 
8.  After deleting DB2 instance. the output of db2set -all is as 
below. 
    * this does not show DB2INSTDEF 
    C:\Program Files\IBM\SQLLIB\BIN>db2set -all 
    [e] DB2PATH=C:\Program Files\IBM\SQLLIB 
    [g] DB2_EXTSECURITY=YES 
    [g] DB2_COMMON_APP_DATA_PATH=C:\ProgramData 
    [g] DB2SYSTEM=VMINSTWIN14 
    [g] DB2PATH=C:\Program Files\IBM\SQLLIB 
    [g] DB2ADMINSERVER=DB2DAS00 
 
9.  Try to do Fixpack update to V105FP6, gets errors for not 
exist "DB2" instance unexpectedly. 
    * Unable to upgrade configuration file. 
 
Root cause: 
   Installer checks/uses default "DB2" instance even if it's 
dropped already. 
 
Symptom: 
   Can not upgrade and setup.trc records not exist default "DB2" 
instance name. 
 
Condition of problem: 
   When the default instance "DB2" has been dropped. 
 
Workaround: 
   Do not drop the default "DB2" instance.
