This parameter defines the default client adapter number for the NETBIOS protocol whose server nname is extracted from DCE Cell Directory Services (CDS). This parameter is applicable to the OS/2 environment only.
This parameter can only be used with DCE.
You can temporarily override the value of this parameter by setting the DB2CLIENTADPT environment variable. If this environment variable contains a non-numeric or out-of-range number, adapter number 0 (zero) is used.
