create mechanism for replicating all system metadata without documents

Description
There will be data objects that do not exist on the CN Metacat but for which we have system metdata. This system metadata must be replicated among CNs.

- Subject changed from find mechanism to replicate sysmeta info for data objects that do not exist on the CNMetacat but for which we have sysmeta to create mechanism for replicating all system metadata without documents
#2 Updated by Ben Leinfelder about 13 years ago
There is now timed replication of systemmetadata-only records. Records that have been updated since the last replication check will be replicated between hosts.
I've also created methods for forcing replication (immediately upon insert/update) but have not decided where calls to this should be made - other than the CNCore implementation for registerSystemMetadata().
Also to consider: a separate replication flag that indicates whether or not system metadata-only records should be persisted across the configured replication servers (there are options for XML and data objects, this would be a third option).
#3 Updated by Ben Leinfelder about 13 years ago
- Status changed from New to Closed
development on this is complete and soon the libclient CNCore implementation will invoke the registerSystemMetadata() method that will exercise/fully test it.
