When you starting DB2 or trying to connect to DB2 10.1 from an application on Windows 7/XP you can get the following error message in db2diag.log file:
2012-10-29-21.59.44.050000+180 I369700H505 LEVEL: Error PID : 16452 TID : 15132 PROC : sqldata.exe INSTANCE: DB2 NODE : 000 HOSTNAME: srv-dm1 EDUID : 15132 FUNCTION: DB2 Common, Cryptography, cryptDynamicLoadGSKitCrypto, probe:998 MESSAGE : ECF=0x90000076=-1879048074=ECF_LIB_CANNOT_LOAD Cannot load the specified library DATA #1 : unsigned integer, 4 bytes 70 DATA #2 : String, 34 bytes C:\IBM\SQLLIB\bin\icc\gsk8iccs.dll
When you run DB2 Installer it offers to install DB2 to C:\Program Files\IBM\SQLLIB directory by default. Often you change this path to something like C:\IBM\SQLLIB, but the installer still can write some other components to C:\Program Files\IBM\.
For example, the installer creates gsk8 and IBM SSH Server directories in C:\Program Files\IBM\ if you do not change their location.
When you get Cannot load the specified library - C:\IBM\SQLLIB\bin\icc\gsk8iccs.dll in the db2diag.log, do the following:
Note. Copy files only from gsk8\lib, do not copy directory lib with files to bin\icc
