The default location of clispb.dat is /usr/lpp/teradata/client/20.00/etc.
The default clispb.dat affects all MF-GTW TTU products (BTEQ, TPT, and SA products) for all users. Each user can copy the default clispb.dat to their home directory and modify it for individual purposes. If clispb.dat is found in the user’s home directory, it overrides the default clispb.dat.
If you want to use clispb.dat from another folder, set the environment variable COPLIB.
JCL example to set COPLIB:
//ENVFILE DD * COPLIB=/home/randomfolder /* //CEEOPTS DD * ENVAR("_CEE_ENVFILE_S=DD:ENVFILE") /*
