[ovirt-users] DWH ETL disconnects from DB (was: [ANN] oVirt 4.3.5 Fifth Release Candidate is now available for testing)

Hi Sandro, It seems this issue is not related to current RC (earliest entry found for 02 Feb 2019). I have followed RH Solution #3338001 ( https://access.redhat.com/solutions/3338001) and last night I didn't have that event in the UI. It seems that I still have exceptions in the logs like : Exception in component tJDBCInput_3 org.postgresql.util.PSQLException: This connection has been closed. at org.postgresql.jdbc2.AbstractJdbc2Connection.checkClosed(AbstractJdbc2Connection.java:822) at org.postgresql.jdbc3.AbstractJdbc3Connection.createStatement(AbstractJdbc3Connection.java:229) at org.postgresql.jdbc2.AbstractJdbc2Connection.createStatement(AbstractJdbc2Connection.java:294) at ovirt_engine_dwh.dailytimekeepingjob_4_3.DailyTimeKeepingJob.tJDBCInput_3Process(DailyTimeKeepingJob.java:1331) at ovirt_engine_dwh.dailytimekeepingjob_4_3.DailyTimeKeepingJob.tPostjob_1Process(DailyTimeKeepingJob.java:1070) at ovirt_engine_dwh.dailytimekeepingjob_4_3.DailyTimeKeepingJob.runJobInTOS(DailyTimeKeepingJob.java:8784) at ovirt_engine_dwh.dailytimekeepingjob_4_3.DailyTimeKeepingJob.runJob(DailyTimeKeepingJob.java:8375) at ovirt_engine_dwh.parallelrun_4_3.ParallelRun.tInfiniteLoop_3Process(ParallelRun.java:3539) at ovirt_engine_dwh.parallelrun_4_3.ParallelRun.tJava_4Process(ParallelRun.java:3300) at ovirt_engine_dwh.parallelrun_4_3.ParallelRun$4.run(ParallelRun.java:5712) 2019-07-17 00:00:00|sykykw|ayRRMN|6ekzCe|OVIRT_ENGINE_DWH|DailyTimeKeepingJob|Default|6|Java Exception|tJDBCInput_3|org.postgresql.util.PSQLException:This connection has been closed.|1 Exception in component tJDBCInput_10 org.postgresql.util.PSQLException: This connection has been closed. at org.postgresql.jdbc2.AbstractJdbc2Connection.checkClosed(AbstractJdbc2Connection.java:822) at org.postgresql.jdbc3.AbstractJdbc3Connection.createStatement(AbstractJdbc3Connection.java:229) at org.postgresql.jdbc2.AbstractJdbc2Connection.createStatement(AbstractJdbc2Connection.java:294) at ovirt_engine_dwh.deletetimekeepingjob_4_3.DeleteTimeKeepingJob.tJDBCInput_10Process(DeleteTimeKeepingJob.java:1493) at ovirt_engine_dwh.deletetimekeepingjob_4_3.DeleteTimeKeepingJob.tPostjob_2Process(DeleteTimeKeepingJob.java:1232) at ovirt_engine_dwh.deletetimekeepingjob_4_3.DeleteTimeKeepingJob.runJobInTOS(DeleteTimeKeepingJob.java:11707) at ovirt_engine_dwh.deletetimekeepingjob_4_3.DeleteTimeKeepingJob.runJob(DeleteTimeKeepingJob.java:11308) at ovirt_engine_dwh.parallelrun_4_3.ParallelRun.tInfiniteLoop_6Process(ParallelRun.java:4174) at ovirt_engine_dwh.parallelrun_4_3.ParallelRun.tJava_5Process(ParallelRun.java:3716) at ovirt_engine_dwh.parallelrun_4_3.ParallelRun$5.run(ParallelRun.java:5758) 2019-07-17 03:00:01|QGmtgL|ayRRMN|6ekzCe|OVIRT_ENGINE_DWH|DeleteTimeKeepingJob|Default|6|Java Exception|tJDBCInput_10|org.postgresql.util.PSQLException:This connection has been closed.|1 I'm not sure how fatal are those, as this type of exceptions are logged for a lot of time - the earliest occurrence I found in the logs is for : 'etlVersion|4.2.4.3' from 2019-01-31 . So , latest RC seems to be OK.
