I think I have reached the end of Google, but still not able to find the part number I need to download the license file for IBM Data Server Client 11.5. Not listed here https://www.ibm.com/support/pages/db2-version-111-activation-key-part-numbers and I start to get tired of the message

LIC1407N You are trying to register an invalid license certificate file

Update

The client will be serving a set of .Net applications hosted on IIS. They are dependent on the db2 catalog konfig 'test' (and 'prod'). The db2 catalog commands is successfully, but when I want to verify the connection to db2 using command

db2 connect to TEST user TESTUSER

I get (when applying the valid password)

SQL1598N  An attempt to connect to the database server failed because of a
licensing problem.  SQLSTATE=42968

If I type a password I know is wrong I get

D:\IBM\SQLLIB\BIN>db2 connect to TEST user TESTUSER
Enter current password for CFFSAFI:
SQL30082N  Security processing failed with reason "24" ("USERNAME AND/OR
PASSWORD INVALID").  SQLSTATE=08001

So the first error with correct password and the last one with the wrong, to my knowledge it confirmes that I'm able to connect to db2

Which is explained here https://www.ibm.com/support/pages/sql1598n-error-connecting-mainframe-db2-ibm-data-server-driver-even-though-db2-connect-license-file-exists-license-directory-install-path (I do not have a license file in the path)

D:\IBM\SQLLIB\BIN>db2licm.exe -l
Product name:                     "IBM Data Server Client"
Product identifier:               "db2client"
Version information:              "11.5"

Got it, as explained here SQL1598N error connecting to mainframe DB2 from IBM Data Server Driver even though DB2 Connect license file exists in the license directory of the install path

It is possible to license the IBM Data Server Driver to connect to mainframe DB2 such as DB2 for z/OS, IBM DB2 for IBM i, and DB2 Server for VM and VSE servers by copying one of these files into the installation_path/license directory.

  • DB2 Connect Personal Edition: db2conpe.lic
  • DB2 Connect Application Server Edition: db2consv_as.lic
  • DB2 Connect Enterprise Edition: db2consv_ee.lic
  • DB2 Connect Unlimited Edition for System i: db2consv_is.lic
  • DB2 Connect Unlimited Edition for System z: db2consv_zs.lic

I did as explained, found the activation key for IBM DB2 Connect Unlimited Edition for System z - Activation 11.5 for Linux, UNIX and Windows Multilingual whic is CC1V0ML and downloaded it and added it - restartet and voila

D:\IBM\SQLLIB\BIN>db2 connect to TEST user TESTUSER
Enter current password for TESTUSER:

Database Connection Information

Database server        = DB2 z/OS 11.1.5
SQL authorization ID   = TESTUSER
Local database alias   = TESTUSER

You don’t need to apply any license to a Db2 client. Db2 Clients are not licensed.
