    • InformixConnection

      public InformixConnection(io.debezium.jdbc.JdbcConfiguration config)
      Creates a new connection using the supplied configuration.
      Parameters:
      config - Configuration instance, may not be null.

  • Method Details

    • getMaxLsn

      public Lsn getMaxLsn() throws SQLException
      Calculates the highest available Log Sequence Number. Tecnically, the _exact_ highest available LSN is not available in the JDBC session, but the current page of the active logical log file is. Each logical log file is a 32-bit address space of 4k pages, thus the log position within the file is the current page number bit-shifted 12 positions to the left. This is also the logical log position the change stream client actually starts from if set to start from the 'CURRENT' position (LSN = 0). (The full logical sequence number is a 64-bit integer where the unique id of the logical log file is placed in the 32 most significant bits.)
      Returns:
      the current highest log sequence number
      Throws:
      SQLException

    • getRealDatabaseName

      public String getRealDatabaseName()

    • retrieveRealDatabaseName

      private String retrieveRealDatabaseName()

    • connectionString

      public String connectionString()
      Returns a JDBC connection string for the current configuration.
      Returns:
      a String where the variables in urlPattern are replaced with values from the configuration
