ALTER GLOBAL
the process terminates (but not if the process is stopped).
the server is waiting for a request and the time since the last request
exceeds the specified value.
the transaction reaches the limits set by the MAXTIME and MAXUPDATES
parameters.
Each transaction spans many server requests and updated records are kept
locked between server requests. If the batch process sends work to many
server processes, the servers processes must access different database
records or a deadlock may occur. The commit timer will not cause the current
transaction to be committed if the process is deadlocked.
ATMFTXTIMEOUT { value | NEVER | OFF }
sets the maximum duration of an automatic transaction, regardless of the TMF
AutoAbort setting. This feature requires TMF version 3.6 or later.
value: is n [ SEC[ONDS] | MIN[UTES] ], between 5 and 510 minutes.
value overrides the TMF AutoAbort timer setting. A value entered as
n SEConds is rounded up to minutes.
NEVER: the transactions is never aborted by TMF due to a timeout.
OFF: the default, specifies that the TMF AutoAbort is in effect.
If TXTIMEOUT is configured on a system that is not running TMF 3.6 or later, a
warning message is displayed, the configuration is updated and the transaction
timeout takes effect when TMF 3.6 is installed.
ATMFWARNLONGTX
sets the frequency of long transaction warning messages displayed in the EMS
log. By default, the warnings are generated every 5 minutes.
The AutoTMF runtime generates periodic EMS messages to alert the operator
of long running transactions, which are usually caused by a program holding
locks and preventing AutoTMF from committing an automatic transaction. The
EMS message displays the transaction identifier of the long running
transaction, the name of the process holding the locks and the time remaining
before the transaction reaches the AutoCommit limit.
value: a number between 1 and 30 minutes, specified as
n [ SEC[ONDS] | MIN[UTES].
A value entered as n SEC[ONDS] is converted to a minute value.
NEVER: suppresses the display of long transaction warning messages.
Note. The AutoTMF AutoCommit timer always applies, regardless of the configured
transaction timeout. If the desired transaction time out value exceeds the configured
AutoCommit timer value, the user should adjust the AutoCommit timer accordingly.
See AutoCommit attribute description above on page
for details.
