Time-controlled monitoring of connections and transactions

UDS-D monitors operations with distributed transactions by means of a timer. The time interval to be selected for the timer is based on the DBH load parameter PP CHCKTIME (see “Monitoring connections and transactions (CHCKTIME)” in chapter "DBH load parameters").

UDS-D monitors

• the logical connections to remote application programs

• secondary subtransactions and checks whether the associated primary subtransactions still exist

• secondary subtransactions in the PTC state

• primary subtransactions that were terminated by the database administrator.
