Moving a Metadata Repository to a New Location on the Same Metadata Server

In most cases, it is neither necessary nor advisable to move metadata repositories to a new location, for the following reasons:
  • Metadata server performance is unlikely to be improved by moving repositories to a faster file system. The metadata server uses an in-memory database, and file system updates are performed in a background thread in SAS 9.2 and later releases.
  • Repositories are unlikely to require a larger amount of disk space than is available on the current file system. In SAS 9.2 and later releases, repositories are stored in compressed data sets. Except in the very largest deployments, storage requirements are unlikely to exceed a total of 1 gigabyte.
    Note: Metadata server logs can cause disk space to fill up if additional logging has been enabled for troubleshooting or other purposes. To avoid this situation, be sure to reset logging to the default level when troubleshooting has been completed.
Because of the complexities involved, metadata repositories should not be moved unless there is a strong reason to do so. Implementation of high-availability failover for the metadata server is one of the few situations in which it might be appropriate to consider moving metadata repositories to a network-available file system.
CAUTION:
Moving a metadata repository is a complex task and is not necessary in most cases. If you determine that you need to move a metadata repository (for example, to support failover), it is strongly recommended that you first contact SAS Technical Support for advice and assistance.
