The values that you specify with the Stream driver TD_MIN_SESSIONS and TD_MAX_SESSIONS attributes are not the only factors that limit the number of sessions that the Stream driver establishes with the database.
The other limiting factors are:
- 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 workstation-attached systems. When the Stream driver executes, the actual session limit is determined by whichever limiting factor is encountered first.
