9.1.6 Preparing the Source and Target Trees
Before performing a merge operation, ensure that the state of synchronization for all servers affected
by the operation is stable. The following table provides prerequisites for preparing source and target
trees for merging.
Because the merge operation is one single transaction, it is not subject to catastrophic failure caused
by power outages or hardware failure. However, you should perform a regular backup of the
eDirectory database before using DSMerge. For more information, see
Chapter 16, “Backing Up
and Restoring Novell eDirectory,” on page 421 .
9.1.7 Synchronizing Time before the Merge
IMPORTANT: Proper configuration of time synchronization is a very involved process. Make sure
you allow enough time to synchronize both trees before you merge the trees.
Novell eDirectory will not work properly if different time sources are used that have different times
or if all servers in a tree are not time synchronized.
Prerequisite Required Action
WANMAN should be turned off on all
servers that hold a replica of the source
tree's Tree partition or the target tree's
Tree partition. Review your WANMAN policy so that WAN communication
restrictions do not interfere with the merge operation. If
required, turn WANMAN off before initiating the merge
operation.
No aliases or leaf objects can exist at
the source tree's Tree object. Delete any aliases or leaf objects at the source tree's Tree
object.
No identical names can exist between
the source and target trees. Rename objects on the source and target trees if identical
names exist. Move objects from one of the containers to a
different container in its tree if you don't want to rename the
container objects, then delete the empty container before
running DSMerge. For more information, see
Chapter 3,
“Managing Objects,” on page 93 .
You can have identical container objects in both trees if they
are not immediately subordinate to the Tree object.
No login connections should exist on
the source tree. Close all connections on the source tree.
The eDirectory version must be the
same on both the source and target
trees. Upgrade all non-eDirectory 8.8 servers that have a replica of
the root partition.
The target tree must have only one
copy of the root replica. Remove all replicas on the target tree except the master
replica.
The schema on both the source and
target trees must be the same. Run DSMerge. If reports indicate schema problems, use
DSRepair to match the schemas. (See
“Importing Remote
Schema” on page 276 for more information.) Run DSMerge
again.
Only one tree can have a security
container subordinate to the tree root. If both the source and target trees have a security container,
remove one container as explained in
Appendix A, “NMAS
Considerations,” on page 601 .
