Modifying the Zone Database

<a name="wp1080641"> </a><p class="pBody">
Modifications to the zone database is done within a session. A session is created at the time of the first 
successful configuration command. On creation of a session, a copy of the zone database is created. Any 
changes done within the session are performed on this copy of the zoning database. These changes in the 
copy zoning database are not applied to the effective zoning database until you commit the changes. 
Once you apply the changes, the session is closed. 

</p>
<a name="wp1080642"> </a><p class="pBody">
If the fabric is locked by another user and for some reason the lock is not cleared, you can force the 
operation and close the session. You must have permission (role) to clear the lock in this switch and 
perform the operation on the switch from where the session was originally created.
