[teiid-issues] [JBoss JIRA] (TEIID-4775) When using external materialization, after transaction timeout, LoadState continues to be LOADING

When using external materialization, after transaction timeout, LoadState continues to be LOADING ------------------------------------------------------------------------------------------------- Key: TEIID-4775 URL: https://issues.jboss.org/browse/TEIID-4775 Project: Teiid Issue Type: Bug Components: Server Affects Versions: 8.7 Environment: * CentOs 7 * Teiid 9.1.2 * Wildfly 10 Reporter: Pedro Inácio Assignee: Ramesh Reddy Fix For: 9.3 For some unknown reason, sometimes a materialized view takes more time to finish the load/update than the one defined in transaction timeout (300 seconds is the default value, and we have configured 600 seconds to try to solve the problem). The transaction reaper will kill the update transaction. The _LoadState_ in _status_ table will be *LOADING*. Any subsequent try to update the view will fail, since the system reads the state as being *LOADING* even if the system is not currently updating it. Example log next. The update took too long (more than 10 minutes [defined transaction timeout]): {code:batch} 2017-02-17 16:10:44,487 INFO [org.teiid.COMMAND_LOG] (NIO6) gZueFR0aNjgi START USER COMMAND: startTime=2017-02-17 16:10:44.487 requestID=gZueFR0aNjgi.11 txID=null sessionID=gZueFR0aNjgi applicationName=JDBC principal=manel vdbName=CountryServiceListVDB vdbVersion=1 sql={call SYSADMIN.loadMatView(?, ?)} 2017-02-17 16:20:44,528 WARN [com.arjuna.ats.arjuna] (Transaction Reaper) ARJUNA012117: TransactionReaper::check timeout for TX 0:ffff0a080174:21ddbdf0:58a71a32:cb in state RUN 2017-02-17 16:20:44,564 WARN [com.arjuna.ats.arjuna] (Transaction Reaper Worker 0) ARJUNA012121: TransactionReaper::doCancellations worker Thread[Transaction Reaper Worker 0,5,main] successfully canceled TX 0:ffff0a080174:21ddbdf0:58a71a32:cb {code} Next I tried to update the view: {code:batch} 2017-02-17 16:29:21,272 INFO [org.teiid.COMMAND_LOG] (NIO2) E1xyKpChGKvC START USER COMMAND: startTime=2017-02-17 16:29:21.272 requestID=E1xyKpChGKvC.7 txID=null sessionID=E1xyKpChGKvC applicationName=JDBC principal=manel vdbName=CountryServiceListVDB vdbVersion=1 sql=EXECUTE SYSADMIN.loadMatView('CountryServiceListCalculatedRaw','country_service_list_calculated_raw') 2017-02-17 16:29:21,391 INFO [org.teiid.COMMAND_LOG] (Worker25_QueryProcessorQueue18136) E1xyKpChGKvC END USER COMMAND: endTime=2017-02-17 16:29:21.391 requestID=E1xyKpChGKvC.7 txID=null sessionID=E1xyKpChGKvC principal=manel vdbName=CountryServiceListVDB vdbVersion=1 finalRowCount=1 {code} And nothing happened.
