DB2 Data Links Manager supports AIX® 5L Version 5.2
DB2 Data Links Manager is available on the Windows 2000 operating system, in addition to Windows NT, AIX, and the Solaris Operating Environment.
DB2 Data Links Manager supports both the Version 8 and Version 7 Solaris Operating Environments.
You can update files while they remain under the control of DB2 Data Links Manager. Linked files are files under the control of the Data Links Manager. Before DB2 Version 8, you had to unlink a file, make changes to the file, then relink the file.
Performance improvements have been made for archive, data recovery, and replication operations on linked files. These improvements: ­ Reduce the time for beginning backups involving linked files­ Reduce the time for running the Reconcile utility ­ Improve the throughput on replication of linked files using DB2 DataPropagator
Improved security features for restricting the linking of files to authorized users.

Withdrawal of DCE-DFS support in Data Links Manager Version 8
Data Links Manager functionality will not be provided for the DCE-DFS environment in Version 8. Data Links Manager continues to provide support for DFSTM in Version 7. Although you might find references to the DFS environment for Data Links Manager in the V8 product, install package, messages, and documentation, these should be ignored, as they are no longer applicable. If you are a Data Links Version 7 user who is dependent upon the DCE-DFS support, you must either use a different storage environment with Data Links Manager Version 8, or you should not move to Data Links Manager Version 8 until you resolved your dependency on DFS.
