+
+The ALTER_QUARANTINE procedure allows us to alter the thresholds, to make them look more like automatically generated quarantines.  
+We can use the procedure to alter the following parameters:
+
+- CPU_TIME
+- ELAPSED_TIME
+- IO_MEGABYTES
+- IO_REQUESTS
+- IO_LOGICAL
+- ENABLED
+- AUTOPURGE
+
+Example of setting the CPU_TIME threshold for the manually created quarantines:
+
+	BEGIN
+	  DBMS_SQLQ.alter_quarantine(
+	    quarantine_name  =>  'SQL_QUARANTINE_8zpc9pwdmb8vr',
+	    parameter_name   =>  'CPU_TIME',
+	    parameter_value  =>  '1');
+	 END;
