105 *
106 * NAME
107 * clone_context
108 *
109 * DESCRIPTION
110 * Clone an existing LogMiner persistent context. The specified persistent
111 * context is duplicated and its session# is returned. The new context
112 * shares the dictionary with the parent context. If the specified SCN is
113 * zero (default) or there are no valid checkpoints at or below it then the
114 * new context is created with start_scn of the parent context.
115 *
116 * With the exception of session# and session_name the new context inherits
117 * all attributes of the parent context and may itself be subsequently
118 * cloned. The shared dictionary is kept intact as long as there are
119 * sharers.
120 *
121 * PARAMETERS
122 * session_id IN: The session# of context to be duplicated.
123 * new_session_name IN: The unique name to be given to the cloned session.
124 * scn IN: SCN at or above a checkpoint where the new context is
125 * to be started. By default, the new context starts at
126 * the start_scn of the parent context.
127 * clone_flags IN : Flag : 0 refers to clone_all
128 * 1 refers to clone_dictionary_only
129 * TRANSACTION
130 * Autonomous
131 *
132 * ERRORS
133 * Error conditions are raised.
