Error description

  • If there are active JDBC connections to a Sybase database
    server when that server is shut down, possibly for maintenance,
    the next time the connection is used by a message flow it does
    not mark the connection as broken after receiving the following
    SQL exception information:
    
    
    SQLSTATE: 08W01
    SQLCODE: -100
    Native error code: 7950
    
    
    A BIP4361W warning message may be written to the system log ,
    and if using JDBC connection pooling, subsequent calls to
    getJDBCType4Connection() might repeatedly fail with the
    following recoverable exception:
    
    
    BIP6267E: There has been a problem establishing a connection to
    the JDBC provider ''myJDBCProvider'' in node
    ''myJavaComputeNode''. Exception details:
    'java.sql.Connection=null'
    
    To recover, the integration server has to be restarted.

    PROBLEM DESCRIPTION:
    If there are active JDBC connections to a Sybase database server
    when that server is shut down, possibly for maintenance, the
    next time the connection is used by a message flow it does not
    mark the connection as broken after receiving the following SQL
    exception information:
    
    SQLSTATE: 08W01
    SQLCODE: -100
    Native error code: 7950
    
    A BIP4361W warning message may be written to the system log, and

    'java.sql.Connection=null'
    
    To recover, the integration server has to be restarted.
    

Problem conclusion

  • The product now recognises some additional Sybase database
    return codes to mean that the JDBC connection is broken.
