ALTER BEGINTRANS

The ALTER BEGINTRANS command changes options related to the automatic

disabling and reenabling of transaction processing, control of the TMF autoabort

feature, and limits on resource managers and transaction branches used in

heterogeneous transaction processing.

TRANSCOUNTTHRESH (integer1, integer2)

RESET TRANSCOUNTTHRESH

specifies the upper and lower limits at which the number of active transactions in

the system automatically disables and reenables new transactions. When the

transaction count reaches integer2, new transactions are disabled. When the

transaction count falls below integer1, they are reenabled, if the other conditions

needed for reenabling (listed under “Usage Guidelines”) exist. You must specify

both values in the command; integer1 must be 1 or greater, but less than

integer2. Neither integer1 nor integer2 can be greater than 1073741824.

To prevent transaction processing from constantly switching back and forth

between the enabled and disabled states, a recommended approach is to set the

values of integer1 and integer2 to result in a large range (such as 100)

between the limits.
