DRCPPurity

Session purity specifies whether an application can reuse a pooled session (Pooled) or must use a new session (New).

Declaration

// C#
public string DRCPPurity {get; set;}

Property Value

OracleDRCPPurity Enumeration values.

Exceptions

  • InvalidOperationException() -  if CPVersion=1.0 and the DRCPPurity is set to a non-null / non-empty string. Applies to unmanaged ODP.NET only.

  • InvalidOperationException() -  if the DRCPPurity is set to a non-null / non-empty string after opening a connection.

  • InvalidOperationException() -  if DRCP is not enabled and the DRCPPurity is set to a non-null / non-empty string.

Remarks

The default value is Pooled.

If set to New, then ODP.NET will dispense a new DRCP connection, rather than try to find an existing connection from the pool. In general, this property is used by applications that want a connection without any preexisting session state set.

If set to Pooled, then ODP.NET will first attempt to use a preexisting connection, that already exists in the DRCP pool.

Only supported for .NET Framework 4 and higher.
