Hi, Matteo, Matteo Sgalaberni wrote: > A my collegue JDBC application that stay in "idle intransaction" 24h/24h Just a little note: For most applications, this can be fixed updating the JDBC driver. Old versions had the behaviour of auto-opening a new backend transaction on commit/rollback, whereas new versions delay that until the first statement in the new transaction is sent. This won't fix applications that do a select and then sit idle for days before committing/rolling back, however. Those should be fixed or use autocommit mode. > Good to know this...but why this behaviour? it'is lovely...:) > > Tom , can you explain why?... It is because the transaction IDs are global per cluster. Markus -- Markus Schaber | Logical Tracking&Tracing International AG Dipl.
