Environment variables supported by the IBM Data Server Driver for ODBC and CLI

The IBM Data Server Driver for ODBC and CLI does not support the command line processor (CLP), which means that you cannot set Db2® registry variables by using the db2set CLP command. Relevant Db2 registry variables are supported with the IBM Data Server Driver for ODBC and CLI as environment variables instead.

IBM Data Server Driver for ODBC and CLI is not part of the IBM® Data Server Client or the IBM Data Server Runtime Client. It must be installed and configured separately.

The Db2 registry variables that will be supported by the IBM Data Server Driver for ODBC and CLI as environment variables are:
