| Parameter | Specify . . . | Minimum | Maximum | Default |
|---|---|---|---|---|
| TNAX | the nonactivity time limit for exclusive control users. | 1 | 16 777 215 | 900 |
The TNAX parameter specifies the maximum elapsed time (in units of 1.048576 seconds) an exclusive control user (EXU) may be considered active without issuing an Adabas command.
If an exclusive control user exceeds the nonactivity time limit, action is taken as described in Adabas Timeout Feature.
If the SMPID parameter specifies a value greater than zero (that is, a multiprocessing nucleus), you may have to specify a larger TNAX value than for a normal nucleus. The chances of data contention are greater, and therefore more time should be allowed.
During this Adabas session, the nonactivity time limit for exclusive control users is about 30 minutes.
ADARUN PROG=ADANUC,TNAX=1800
You can override this parameter setting for an individual user or for all users:
Override the setting for an individual user by specifying a different value in the Adabas control block for an OP command. See the discussion of the OP command in the Adabas Command Reference documentation.
Override the setting for all users with an Adabas TNAX operator command or with the OPERCOM function of the ADADBS utility (described in the Adabas Utilities documentation).
