The hierarchical structure for each of these systems is comparable, and it is possible for any domain tree to be replicated in the DIT. The <CODE>DUMP_LDAP</CODE> command also enables rearrangement of the tree structure during migration, from any domain structure to any possible other DIT structure.</P><A NAME="560180"></A><P CLASS="BP">Oracle Names LDAP Proxy servers, which are used after the data is migrated into a directory server, rely on topology checkpoint files. Checkpoint files are generated from the old Oracle Names administrative region as source topology data for the proxy server. This topology data defines the region structure for all Oracle Names servers or Oracle Names LDAP Proxy servers. Every region has a single topology definition; each server's topology checkpoint file should be an identical replica of this definition. By default, the topology checkpoint file has a file name of <CODE>cktop.ora</CODE> and resides in the <CODE>$ORACLE_HOME/network/names</CODE> on UNIX, and the <EM><CODE>ORACLE_HOME</CODE></EM><CODE>\network\names</CODE> on Windows NT. </P><A NAME="560181"></A><P CLASS="BP">Most cases of migration from multiple administrative regions in Oracle Names to a DIT structure that is not the same requires modification of the region structure in the topology file. Region restructuring occurs if changes are made to domains which are definitive elements of the topology, or if the region boundaries are altered. Every possible case of domain restructuring may or may not require region restructuring. For instance, in a single-region network you can change the domain structure without requiring a topology change. The following constitute a topology change:</P><UL CLASS="LB1"><LI CLASS="LB1" TYPE="DISC"><A NAME="560182"></A>Addition or removal of any Oracle Names servers, as well as modification of an Oracle Names server's name or protocol address <P><LI CLASS="LB1" TYPE="DISC"><A NAME="560183"></A>Modification of domain definitions for an administrative region or its delegated administrative regions <P> ⌨️ 快捷键说明
