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

Thanks Didi, I have checked the log and I don't see anything related to that time. /var/log/ovirt-engine-dwh/ovirt-engine-dwhd.log: 2019-07-18 03:00:01|rzhdBd|ayRRMN|6ekzCe|OVIRT_ENGINE_DWH|DeleteTimeKeepingJob|Default|6|Java Exception|tJDBCInput_10|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) 2019-07-18 03:01:16|CoHZYa|ayRRMN|6ekzCe|OVIRT_ENGINE_DWH|DeleteTimeKeepingJob|Default|6|Java Exception|tJDBCInput_10|org.postgresql.util.PSQLException:This connection has been closed.|1 (END) In the correlated logs there is nothing for that time.

So , latest RC seems to be OK. Thanks, changing subject accordingly. Can you please check PG logs at the same times of these errors? Should be in /var/opt/rh/rh-postgresql10/lib/pgsql/data/log .
