The location of instance information and global registry information has been changed. Starting with DB2 Version 9.7, the profiles.reg and default.env files are removed from the DB2 installation path.
In DB2 Version 9.5, the DB2 Instance Profile Registry was located in the profiles.reg file, and the DB2 Global-Level Profile Registry was located in the default.env file. These files were in the DB2 installation path.
DB2 instance information and global registry information is stored in the global registry (global.reg).
