Exception In Thread "main" Java.sql.sqlrecoverableexception: Io Error: Connection Reset
Latest reply 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. java.sql.sqlrecoverableexception io error the network adapter could not establish Database Machine: Oracle 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.

Cause In Java 6u29, there was a bug introduced which prevents SSL connections to SQL Server 2008 R2. This bug was logged with Oracle as Bug ID: 7103725. Resolution Oracle delivered a fix in 6u30, although for at least one affected client not even Java 1.7 worked. Users can get around this bug by downgrading their version of Java (version 1.6.0_24 is confirmed to work) or by passing Java the following property and value: -Djsse.enableCBCProtection=false The flag "jsse.enableCBCProtection=false" will disable CBC protection in your SSL connection. You can read more about SSL and CBC here: http://en.wikipedia.org/wiki/Transport_Layer_Securityhttp://en.wikipedia.org/wiki/Block_cipher_modes_of_operation#Cipher-block_chaining_.28CBC.29 The CBC protection covers the Browser Exploit Against SSL/TLS (BEAST) threat and a security vulnerability in an SSL socketFactory method. To learn more about BEAST you can search Google : https://www.google.com/search?q=Browser%20Exploit%20Against%20SSL/TLS Was this helpful? Yes No T

Please note that the effect of the two given commands is gone on reboot. This is really a database issue, not a JobScheduler one. But here is explained what happens to bring you to a situation where you can solve the problem.The fact is, that jdbc reads from dev/random to get random numbers. The difference with /dev/urandom is, that /dev/urandom does not block if no random numbers are available. That is the reason, the two lines above solves your problem (but only until next reboot).JDBC needs the random numbers to encrypt the connect string.Normally /dev/random is used for a high quality of randomness. But when the entropy pool is empty reading from /dev/random will block.You can check your pool with /dev/random will deliver the next random number when the pool has reached more than 64 entropy units.and the poolsize (normally 4096) with If the "entropy_avail" is to small (JDBC needs 40 bytes of secure random numbers) you have to increase the pool by producing some environmental noise. This could be a problem, when you have a headless network server (no console) as the noise is produced by keyboard mouse etc.What you can do ismake sure that your entropy pool is big enoughadd in sos.ini (to have random numbers generated with less security) Also add this to all jobs in the java option section that make use of
