Method for Synchronizing LAN Server Aliases with
a method for synchronizing the IBM* OS/2* LAN
Server aliases with the Distributed Computing Environment (DCE**)
The IBM OS/2 LAN
Server 4.0 enterprise server takes advantage
of the Distributed Computing Environment (DCE) directory architecture
by storing LAN Server aliases in the DCE directory namespace. Since
LAN Server legacy clients (LS 4.0 baase and below) should be able to
directly access the resources on an enterprise server, the alias
information is also stored in the LAN Server Domain Control Database
(DCDB) in the legacy format.
administration from a LAN Server 4.0 enterprise
workstation will only update the alias definitions stored in the DCE
directory namespace, the LAN Server alias information stored in the
directory namespace will not be consistent with the LAN Server DCDB.
A method for keeping the alias information in both these databases
synchronized is needed.
Synchronization Process, DIRSYNCH, was developed
as a LAN Server service to solve this problem. A set of directory
mapper Application Programming Interfaces (APIs) were developed for
mapping the LAN Server alias attributes to the Cell Directory Service
(CDS) alias objects. The mapper APIS maintain a list of updated
alias definition changes on a per domain basis. The dirsynch process
uses the mapper interfaces to retrieve this update list and to check
for completion of updates.
