Enum OracleConnection.ConnectionValidation

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<OracleConnection.ConnectionValidation>
    Enclosing interface:
    OracleConnection
    public static enum OracleConnection.ConnectionValidation
extends java.lang.Enum<OracleConnection.ConnectionValidation>
    Specifiers for how much effort to put into validating a Connection. The amount of effort put into checking should be non-decreasing from NONE (least effort) to COMPLETE (most effort). Exactly what is checked is implementation dependent.

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      COMPLETE
      everything that can be checked is working.
      INBAND_DOWN
      The JDBC driver validates the connection by reading the inband down event in non-blocking mode.
      LOCAL
      NONE plus check local resources.
      NETWORK
      SOCKET plus the network is intact (network PING).
      NONE
      isValid fails only if the Connection is closed.
      SERVER
      NETWORK plus significant server processes are running.
      SOCKET
      LOCAL plus the server isn't obviously unreachable (dead socket).

      • values

        public static OracleConnection.ConnectionValidation[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (OracleConnection.ConnectionValidation c : OracleConnection.ConnectionValidation.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static OracleConnection.ConnectionValidation valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
