Symptom
- You receive HANA Alert 'Uncommitted Write Transaction' (Alert ID 48).
- The corresponding Alert text (as displayed in HANA Studio) is:
'Uncommitted write transaction running for n minutes found. Transaction ID: <id>. Client PID: <pid>.' - These alerts are also recorded in the alert trace of the indexserver (indexserver_alert_<host>.trc), for eg:
long running uncommitted write transaction detected: CONNECTION ID = 200647, HOST = <dbhost>:30003, CLIENT HOST = <clienthost>, CLIENT PID = 11567, TRANSACTION_ID = "902", TRANSACTION TOTAL EXECUTED TIME = 6321 sec
The long running uncommitted write transaction possibly incurs performance degradation of HANA database. Please commit/rollback a transaction in application or kill the connection by "ALTER SYSTEM DISCONNECT SESSION '200647' "
