The values that are specified with the Export driver TD_MAX_SESSIONS and TD_MIN_SESSIONS
attributes are not the only factors limiting the number of sessions that the Export
driver establishes with the Teradata Database.
The other limiting factors are:
The Teradata Database limit of one session per AMP.
The platform limit on the maximum number of sessions per application. This value is
defined in the COP Interface software file, clispb.dat, under the max_num_sess variable. You can use the TDP SET MAXSESSIONS command to specify a platform limit.
The default TDP MAXSESS value is 1024 sessions.
The limit of the network protocol software on network-attached systems. When the Export
driver executes, the actual session limit is determined by whichever limiting factor
is encountered first.
Note: The Export driver will terminate with an error message if one or more instance cannot
