Io Error Connection Reset Oracle 11g
on Sep 29, 2009 10:10 AM by 509850 JDBC Connection Reset when using many processes on 64 bit system 716218 Jan 21, 2015 10:56 AM Hi, we've a annoying JDBC connection problem since we migrated our Java server to a 64 bit operating system. Here our environment. Database Machine: Oracle exception in thread "main" java.sql.sqlrecoverableexception: io error: connection reset 10g Linux 32 Bit (but same problem on 64 Bit) Application Servers Machine: JDBC driver 11.1.0.6 SUN Java 1.6.0_06 64bit Linux 64 bit (SLES 10 SP2) We have 6 different Java server processes (but with the same code) which all create some connections to the same database (running on a different Hardware). All 6 Java server processes starting at the same time (via scripts). Everything was fine, until we migrated the application server machine from 32 bit Linux to 64 bit Linux. From this day on, the half (or one more or less) of our application server processes can't longer connect to the database. The application server processes which have the problem product the following stack trace: java.sql.SQLRecoverableException: I/O Exception: Connection reset at oracle.jdbc.driver.SQLStateMapping.newSQLException(SQLStateMapping.java:281) at oracle.jdbc.driver.DatabaseError.newSQLException(DatabaseError.java:118) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:224) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:296) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:611) at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:455) at oracle.jdbc.driver.PhysicalConnection.

Flyway 4.0 Assignees No one assigned 4 participants KevinSheedy commented Aug 11, 2015 The Oracle JDBC driver has a known issue on some linux systems. When using flyway, it manifests itself as an https://community.oracle.com/thread/943911 intermittent failure with the message: ERROR: Unable to obtain Jdbc connection from DataSource .... IO Error: Connection reset The problem can be fixed by starting Java with the following JVM param: -Djava.security.egd=file:/dev/../dev/urandom To fix it on my system, I replaced this line in the flyway script: "$JAVA_CMD" -cp "$CP" org.flywaydb.commandline.Main "$@" With this one: "$JAVA_CMD" -Djava.security.egd=file:/dev/../dev/urandom -cp "$CP" org.flywaydb.commandline.Main "$@" Do you think it would be worth adding a https://github.com/flyway/flyway/issues/1077 feature to flyway to allow JVM params to be passed in as a setting, without having to modify the original flyway file? ThomasRasmussen commented Sep 17, 2015 I ran into problems with Connection Reset towards Oracle, and this option actually makes a big difference... My builds actually runs in less than 5 seconds where it would often fail after the first call to flyway. Ie. if I did a flyway:info this would run OK once, but then the following flyway runs will fail with connection reset... Connecting to Oracle with ie. SQLDeveloper works fine, so it is not a DB issue. Apparently it is an issue in Java: http://stackoverflow.com/questions/137212/how-to-solve-performance-problem-with-java-securerandom davidkarlsen commented Sep 17, 2015 Yes. The entropy problem exists on Linux. Which os are you running on? 17. sep. 2015 8:00 a.m. skrev "Thomas Rasmussen"
