-W
option specifies the password for the gpmon user. The gpcc
command normally gets the password from the $PGPASSWD
environment variable or the .pgpass
file in the gpadmin user’s home directory. If the password is not available with either of these methods, the -W
option must be included to specify the password whenever you run gpcc
