The DB2 Connect Server is not needed for IBM Spectrum Control. The permanent license for Db2 Advanced Workgroup Server Edition is what Spectrum Control uses. Remember, if you remove the license, you do not want to uninstall the application (IBM Spectrum Control).If you need to remove the Db2 license, use either of the following methods:
Login as the SYSADM user on UNIX/Linux or a user which belongs to the Local Administrators group on Windows. Run "db2licm -r product identifier". To get the product identifier for a specific product, invoke the db2licm command with the -l option.
Login as user ROOT on UNIX/Linux or a user which belongs to the Local Administrators group on Windows. Rename the nodelock file to nodelock.bak and re-add any licenses that you want to keep on the machine. To re-add the license run "db2licm -a filename". The filename will end with a .lic extension. For example "db2licm -a db2ese_c.lic".
Please note the location of the nodelock:
