This method clears all connections from all the connection pools.

Declaration

// C#
public static void ClearAllPools();

Remarks

This call is analogous to calling ClearPool for all the connection pools that are created for the application.

Exceptions

InvalidOperationException – No connection pool could be found for the application.

Example

// C#
// Sample demonstrating the use of ClearAllPools API in OracleConnection class
 
using System;
using Oracle.DataAccess.Client;
 
class ClearAllPoolsSample
{
  static void Main()
  {
    Console.WriteLine("Running ClearAllPools sample..." );
    // Set the connection string
    string strConn = "User Id=scott;Password=tiger;Data Source=oracle;" +
           "Min pool size=5;";
    OracleConnection conn = new OracleConnection(strConn);
    
    // Create another connection object with a different connection string
    string strConnNew = "User Id=scott;Password=tiger;Data Source=oracle;";
    OracleConnection connNew = new OracleConnection(strConnNew);
 
    // Open the connections. Separate pools are created for conn and connNew
    conn.Open();
    connNew.Open();
    
    // Clears the pools associated with conn and connNew
    OracleConnection.ClearAllPools ();
 
    // cleanup
    conn.Close();
    connNew.Close();
    Console.WriteLine("Done!");
  }
